22
After the application is compiled, run it as follows:
23
24
    java -jar build/libs/scrivenvar.jar
25
26
On Windows:
27
28
    java -jar build\libs\scrivenvar.jar

# Installers
31
32
This section describes how to set up the development environment and
33
build native executables for supported operating systems.
34
35
## Setup
36
37
Follow these one-time setup instructions to begin:
38
39
1. Ensure `$HOME/bin` is set in the `PATH` environment variable.
40
1. Move `build-template` into `$HOME/bin`.
41
42
Setup is complete.
43
44
## Binaries
45
46
Run the `installer` script to build platform-specific binaries, such as:
47
48
    ./installer -V -o linux
49
50
The `installer` script:
51
52
* downloads a JDK;
53
* generates a run script;
54
* bundles the JDK, run script, and JAR file; and
55
* creates a standalone binary, so no installation required.
56
57
Run `./installer -h` to see all command-line options.
58
59
# Versioning
60
61
Version numbers are read directly from Git using a plugin. The version
62
number is written to `app.properties`, a properties file in the `resources`
63
directory that can be read from within the application.

# pluralize.R
11
12
This file defines a function that implements most of Damian Conway's [An Algorithmic Approach to English Pluralization](http://blob.perl.org/tpc/1998/User_Applications/Algorithmic%20Approach%20Plurals/Algorithmic_Plurals.html).
13
14
## Usage
15
16
Example usages of the pluralize function include:
17
18
    `r#pluralize( 'mouse' )` - mice
19
    `r#pluralize( 'buzz' )` - buzzes
20
    `r#pluralize( 'bus' )` - busses
21
22
# possessive.R
23
24
This file defines a function that applies possessives to English words.
25
26
## Usage
27
28
Example usages of the possessive function include:
29
30
    `r#pos( 'Ross' )` - Ross'
31
    `r#pos( 'Ruby' )` - Ruby's
32
    `r#pos( 'Lois' )` - Lois'
33
    `r#pos( 'my' )` - mine
34
    `r#pos( 'Your' )` - Yours

# Introduction

This document describes how to use the application.

# Variable definitions
6
7
Variable definitions provide a way to insert key names having associated values into a document. The variable names and values are declared inside an external file using the [YAML](http://www.yaml.org/) file format. Simply put, variables are written in the file as follows:
8
9
```
10
key: value
11
```
12
13
Any number of variables can be defined, in any order:
14
15
```
16
key_1: Value 1
17
key_2: Value 2
18
```
19
20
Variables can reference other variables by enclosing the key name within dollar symbols:
21
22
```
23
key: Value
24
key_1: $key$ 1
25
key_2: $key$ 2
26
```
27
28
Variables can use a nested structure to help group related information:
29
30
```
31
novel:
32
  title: Book Title
33
  author: Author Name
34
  isbn: 978-3-16-148410-0
35
```
36
37
Use a period to reference nested keys, such as:
38
39
```
40
novel:
41
  author: Author Name
42
copyright:
43
  owner: $novel.author$
44
```
45
46
Save the variable definitions in a file having an extension of `.yaml` or `.yml`.
47
48
# Document editing
49
50
The application's purpose is to completely separate the document's content from its presentation. To achieve this, documents are composed using a [plain text](http://spec.commonmark.org/0.28/) format.
51
52
## Create document
53
54
Start a new document as follows:
55
56
1. Start the application.
57
1. Click **File → New** to create an empty document to edit.
58
1. Click **File → Open** to open a variable definition file.
59
1. Change **Source Files** to **Definition Files** to list definition files.
60
1. Browse to and select a file saved with a `.yaml` or `.yml` extension.
61
1. Click **Open**.
62
63
The variable definitions appear in the variable definition pane under the heading of **Definitions**.
64
65
## Edit document
66
67
Edit the document as normal. Notice how the preview pane updates as new content is added. The toolbar shows various icons that perform different formatting operations. Try them to see how they appear in the preview pane. Other operations not shown on the toolbar include:
68
69
* Struck text (enclose the words within `~~` and `~~`)
70
* Horizontal rule (use `---` on an otherwise empty line).
71
72
The preview pane shows one way to interpret and format the document, but many other presentations are possible.
73
74
## Insert variable
75
76
Let's assume that the variable definitions loaded into the application include:
77
78
```
79
novel:
80
  title: Diary of $novel.author$
81
  author: Anne Frank
82
```
83
84
To reference a variable, type in the key name enclosed within dollar symbols, such as:
85
86
```
87
The novel "$novel.title$" is one of the most widely read books in the world.
88
```
89
90
The preview pane shows:
91
92
> The novel "Diary of Anne Frank" is one of the most widely read books in the world.
93
94
As it is laborious to type in variable names, it is possible to inject the variable name using autocomplete. Accomplish this as follows:
95
96
1. Create a new file.
97
1. Type in a partial variable value, such as **Dia**.
98
1. Press `Ctrl+Space` (hold down the `Control` key and tap the spacebar).
99
100
The editor shows:
101
102
```
103
$novel.title$
104
```
105
106
The preview pane shows:
107
108
```
109
Diary of Anne Frank
110
```
111
112
The variable name is inserted into the document and the preview pane shows the variable's value.

# Introduction
2
3
This document describes how to use the [R](https://www.r-project.org/)
4
programming language from within the application. The application uses an
5
interpreter known as [Renjin](https://www.renjin.org/) to integrate with R.
6
7
# Hello world
8
9
Complete the following steps to see R in action:
10
11
1. Start the application.
12
1. Click **File → New** to create a new file.
13
1. Click **File → Save As**.
14
1. Set **Name** to: `addition.Rmd`
15
1. Click **Save**.
16
17
Setting the file name extension tells the application what processor to
18
use when transforming the contents for display in the preview pane. Continue
19
by typing in the following text, including the backticks:
20
21
```r
22
`r#1 + 1`
23
```
24
25
The preview pane shows the result of `1` plus `1`:
26
27
```
28

29
```

# Bootstrap script
32
33
Being able to run R code while editing an R Markdown document is convenient.
34
Having the ability to call functions is where the power of R can be
35
leveraged.
36
37
Complete the following steps to call an R function from your own library:
38
39
1. Click **File → New** to create a new file.
40
1. Click **File → Save As**.
41
1. Browse to your home directory.
42
1. Set **Name** to: `library.R`.
43
1. Click **Save**.
44
1. Set the contents to:
45
    ``` r
46
    sum <- function( a, b ) {
47
      a + b
48
    }
49
    ```
50
1. Click the **Save** icon.
51
1. Click **R → Script**.
52
1. Set the **R Startup Script** contents to:
53
    ``` r
54
    source( 'library.R' );
55
    ```
56
1. Click **OK**.
57
1. Create a new file.
58
1. Set the contents to:
59
    ``` r
60
    `r#sum( 5, 5 )`
61
    ```
62
1. Save the file as `sum.R`.
63
64
The preview panel shows the result of calling the `sum` function:
65
66
```
67
10.0
68
```
69
70
This shows how the bootstrap script can load `library.R`, which defines
71
a `sum` function that is called by name in the Markdown document.
72
73
# Working directory
74
75
R files may be sourced from any directory, not just the user's home
76
directory. Accomplish this as follows:
77
78
1. Click **R → Directory**.
79
1. Set **Directory** to a different directory.
80
1. Click **OK**.
81
1. Create the directory if it does not exist.
82
1. Move `library.R` into the directory.
83
1. Append a new function to `library.R` as follows:
84
    ``` r
85
    mul <- function( a, b ) {
86
      a * b
87
    }
88
    ```
89
1. Click **R → Script**.
90
1. Set the **R Startup Script** contents to:
91
    ``` r
92
    setwd( '$application.r.working.directory$' );
93
    source( 'library.R' );
94
    ```
95
1. Change `sum.Rmd` to:
96
    ``` r
97
    `r#mul( 5, 5 )`
98
    ```
99
1. Close the file `sum.Rmd`.
100
1. Confirm saving the file when prompted.
101
1. Re-open `sum.Rmd`.
102
103
The preview panel shows:
104
105
```
106
25.0
107
```
108
109
Calling `setwd` using `'$application.r.working.directory$'` changes the
110
working directory where the R engine searches for source files.
111
112
# YAML definitions
113
114
To see how variable definitions work in R, try the following:
115
116
1. Create a new file.
117
1. Change the contents to (use spaces not tabs):
118
    ``` yaml
119
    project:
120
      title: Project Title
121
      author: Author Name
122
    ```
123
1. Save the file as `definitions.yaml`.
124
1. Click **File → Open**.
125
1. Set **Source Files** to **Definition Files**.
126
1. Select `definitions.yaml`.
127
1. Click **Open**.
128
1. Open `sum.Rmd` if it is not already open.
129
1. Type: `je`
130
1. Press `Ctrl+Space`
131
132
The editor inserts the following text (matches `je` against Pro**je**ct):
133
134
``` r
135
`r#x( v$project$title )`
136
```
137
138
The preview panel shows:
139
140
```
141
r#x( 'Project Title' )
142
```
143
144
This is because the application inserts definition reference names based
145
on the type of file being edited. By default, the R engine does not have
146
a function named `x` defined.
147
148
Continue as follows:
149
150
1. Click **R → Script**.
151
1. Append the following:
152
    ``` r
153
    x <- function( s ) {
154
      tryCatch( {
155
        r = eval( parse( text = s ) )
156
157
        ifelse( is.atomic( r ), r, s );
158
      },
159
      warning = function( w ) { s },
160
      error = function( e ) { s } )
161
    }
162
    ```
163
1. Click **OK**.
164
1. Close and re-open `sum.Rmd`.
165
166
The preview panel shows:
167
168
```
169
25.0
170
171
Project Title
172
```
173
174
The `x` function attempts to evaluate the expression defined by the YAML
175
variable. This means that the YAML definitions can also include expressions
176
that R is capable of evaluating.
177
178
While the `x` function can be defined within the R Startup Script, it is
179
better practice to put it into its own library so that it can be reused
180
outside of the application.

# Introduction
2
3
The Scalable Vector Graphics (SVG) drawing software---[Batik](https://xmlgraphics.apache.org/batik/)---that's used by the application may be unable to read certain SVG files produced by [Inkscape](https://inkscape.org/). The result is that embedding the vector graphics files may trigger the following issues:
4
5
* Unable to create nested element
6
* Black blocks, no text displayed
7
* Black text instead of coloured
8
9
The remainder of this document explains these problems and how to fix them.
10
11
# Nested element
12
13
When referencing a vector graphic using Markdown, the status bar may show the following error:
14
15
> The current document is unable to create an element of the requested type (namespace: http://www.w3.org/2000/svg, name: flowRoot).
16
17
This error is due to a version mismatch of the `flowRoot` element that Inkscape creates.
18
19
## Fix
20
21
Resolve the issue by changing the SVG version number as follows:
22
23
1. Edit the vector graphics file using any text editor.
24
1. Find `version="1.1"` and change it to `version="1.2"`.
25
1. Save the file.
26
27
The SVG will now appear inside the application; however, the text may appear as black blocks.
28
29
# Black blocks
30
31
Depending on how text is added to a vector graphic in Inkscape, the text may be inserted within an element called a `flowRoot`. Although Batik recognizes `flowRoot` for SVG version 1.2, it cannot fully interpret the contents. Black blocks are drawn instead of the text, such as those depicted in the following figure:
32
33
![Missing text](images/blocked-text.png)
34
35
## Fix
36
37
Resolve the issue by "unflowing" all text elements as follows:
38
39
1. Start Inkscape.
40
1. Load the SVG file.
41
1. Select all the text elements.
42
1. Click **Text → Unflow**.
43
44
The text may change size and position; recreate the text without dragging using the text tool. After all the text areas have been recreated, continue as follows:
45
46
1. Click **Edit → XML Editor**.
47
1. Expand the **XML Editor** to see more elements.
48
1. Delete all elements named `svg:flowRoot`.
49
1. Save the file.
50
51
When the illustration is reloaded, the black blocks will have disappeared, but the text elements ignore any assigned colour.
52
53
# Black text
54
55
When an SVG `style` attribute contains a reference to `-inkscape-font-specification`, Batik ignores all values that follow said reference. This results in black text, such as:
56
57
![Black text](images/black-text.png)
58
59
## Fix
60
61
Resolve the issue of colourless text as follows:
62
63
1. Open the SVG file in a plain text editor.
64
1. Remove all references `-inkscape-font-specification:'<FONT>';`, including the trailing (or leading) semicolon.
65
1. Save the file.
66
67
When the illustration is reloaded, the colours will have reappeared, such as:

      excluding communication that is conspicuously marked or otherwise
61
      designated in writing by the copyright owner as "Not a Contribution."
62
63
      "Contributor" shall mean Licensor and any individual or Legal Entity
64
      on behalf of whom a Contribution has been received by Licensor and
65
      subsequently incorporated within the Work.
66
67
   2. Grant of Copyright License. Subject to the terms and conditions of
68
      this License, each Contributor hereby grants to You a perpetual,
69
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
70
      copyright license to reproduce, prepare Derivative Works of,
71
      publicly display, publicly perform, sublicense, and distribute the
72
      Work and such Derivative Works in Source or Object form.
73
74
   3. Grant of Patent License. Subject to the terms and conditions of
75
      this License, each Contributor hereby grants to You a perpetual,
76
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
77
      (except as stated in this section) patent license to make, have made,
78
      use, offer to sell, sell, import, and otherwise transfer the Work,
79
      where such license applies only to those patent claims licensable
80
      by such Contributor that are necessarily infringed by their
81
      Contribution(s) alone or by combination of their Contribution(s)
82
      with the Work to which such Contribution(s) was submitted. If You
83
      institute patent litigation against any entity (including a
84
      cross-claim or counterclaim in a lawsuit) alleging that the Work
85
      or a Contribution incorporated within the Work constitutes direct
86
      or contributory patent infringement, then any patent licenses
87
      granted to You under this License for that Work shall terminate
88
      as of the date such litigation is filed.
89
90
   4. Redistribution. You may reproduce and distribute copies of the
91
      Work or Derivative Works thereof in any medium, with or without
92
      modifications, and in Source or Object form, provided that You
93
      meet the following conditions:
94
95
      (a) You must give any other recipients of the Work or
96
          Derivative Works a copy of this License; and
97
98
      (b) You must cause any modified files to carry prominent notices
99
          stating that You changed the files; and
100
101
      (c) You must retain, in the Source form of any Derivative Works
102
          that You distribute, all copyright, patent, trademark, and
103
          attribution notices from the Source form of the Work,
104
          excluding those notices that do not pertain to any part of
105
          the Derivative Works; and
106
107
      (d) If the Work includes a "NOTICE" text file as part of its
108
          distribution, then any Derivative Works that You distribute must
109
          include a readable copy of the attribution notices contained
110
          within such NOTICE file, excluding those notices that do not
111
          pertain to any part of the Derivative Works, in at least one
112
          of the following places: within a NOTICE text file distributed
113
          as part of the Derivative Works; within the Source form or
114
          documentation, if provided along with the Derivative Works; or,
115
          within a display generated by the Derivative Works, if and
116
          wherever such third-party notices normally appear. The contents
117
          of the NOTICE file are for informational purposes only and
118
          do not modify the License. You may add Your own attribution
119
          notices within Derivative Works that You distribute, alongside
120
          or as an addendum to the NOTICE text from the Work, provided
121
          that such additional attribution notices cannot be construed
122
          as modifying the License.
123
124
      You may add Your own copyright statement to Your modifications and
125
      may provide additional or different license terms and conditions
126
      for use, reproduction, or distribution of Your modifications, or
127
      for any such Derivative Works as a whole, provided Your use,
128
      reproduction, and distribution of the Work otherwise complies with
129
      the conditions stated in this License.
130
131
   5. Submission of Contributions. Unless You explicitly state otherwise,
132
      any Contribution intentionally submitted for inclusion in the Work
133
      by You to the Licensor shall be under the terms and conditions of
134
      this License, without any additional terms or conditions.
135
      Notwithstanding the above, nothing herein shall supersede or modify
136
      the terms of any separate license agreement you may have executed
137
      with Licensor regarding such Contributions.
138
139
   6. Trademarks. This License does not grant permission to use the trade
140
      names, trademarks, service marks, or product names of the Licensor,
141
      except as required for reasonable and customary use in describing the
142
      origin of the Work and reproducing the content of the NOTICE file.
143
144
   7. Disclaimer of Warranty. Unless required by applicable law or
145
      agreed to in writing, Licensor provides the Work (and each
146
      Contributor provides its Contributions) on an "AS IS" BASIS,
147
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148
      implied, including, without limitation, any warranties or conditions
149
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150
      PARTICULAR PURPOSE. You are solely responsible for determining the
151
      appropriateness of using or redistributing the Work and assume any
152
      risks associated with Your exercise of permissions under this License.
153
154
   8. Limitation of Liability. In no event and under no legal theory,
155
      whether in tort (including negligence), contract, or otherwise,
156
      unless required by applicable law (such as deliberate and grossly
157
      negligent acts) or agreed to in writing, shall any Contributor be
158
      liable to You for damages, including any direct, indirect, special,
159
      incidental, or consequential damages of any character arising as a
160
      result of this License or out of the use or inability to use the
161
      Work (including but not limited to damages for loss of goodwill,
162
      work stoppage, computer failure or malfunction, or any and all
163
      other commercial damages or losses), even if such Contributor
164
      has been advised of the possibility of such damages.
165
166
   9. Accepting Warranty or Additional Liability. While redistributing
167
      the Work or Derivative Works thereof, You may choose to offer,
168
      and charge a fee for, acceptance of support, warranty, indemnity,
169
      or other liability obligations and/or rights consistent with this
170
      License. However, in accepting such obligations, You may act only
171
      on Your own behalf and on Your sole responsibility, not on behalf
172
      of any other Contributor, and only if You agree to indemnify,
173
      defend, and hold each Contributor harmless for any liability
174
      incurred by, or claims asserted against, such Contributor by reason
175
      of your accepting any such warranty or additional liability.

41
      form, that is based on (or derived from) the Work and for which the
42
      editorial revisions, annotations, elaborations, or other modifications

      represent, as a whole, an original work of authorship. For the purposes
44
      of this License, Derivative Works shall not include works that remain

46
      the Work and Derivative Works thereof.

82
      institute patent litigation against any entity (including a
83
      cross-claim or counterclaim in a lawsuit) alleging that the Work
84
      or a Contribution incorporated within the Work constitutes direct
85
      or contributory patent infringement, then any patent licenses
86
      granted to You under this License for that Work shall terminate

93
94
      (a) You must give any other recipients of the Work or
95
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
98
          stating that You changed the files; and
99
100
      (c) You must retain, in the Source form of any Derivative Works
101
          that You distribute, all copyright, patent, trademark, and
102
          attribution notices from the Source form of the Work,
103
          excluding those notices that do not pertain to any part of
104
          the Derivative Works; and
105
106
      (d) If the Work includes a "NOTICE" text file as part of its
107
          distribution, then any Derivative Works that You distribute must
108
          include a readable copy of the attribution notices contained
109
          within such NOTICE file, excluding those notices that do not
110

111
          of the following places: within a NOTICE text file distributed

116
          of the NOTICE file are for informational purposes only and
117
          do not modify the License. You may add Your own attribution
118
          notices within Derivative Works that You distribute, alongside
119
          or as an addendum to the NOTICE text from the Work, provided
120
          that such additional attribution notices cannot be construed
121
          as modifying the License.
122
123
      You may add Your own copyright statement to Your modifications and
124
      may provide additional or different license terms and conditions
125
      for use, reproduction, or distribution of Your modifications, or
126
      for any such Derivative Works as a whole, provided Your use,
127
      reproduction, and distribution of the Work otherwise complies with
128
      the conditions stated in this License.
129
130
   5. Submission of Contributions. Unless You explicitly state otherwise,
131
      any Contribution intentionally submitted for inclusion in the Work
132
      by You to the Licensor shall be under the terms and conditions of

134
      Notwithstanding the above, nothing herein shall supersede or modify

      the terms of any separate license agreement you may have executed
136
      with Licensor regarding such Contributions.
137
138
   6. Trademarks. This License does not grant permission to use the trade

      Contributor provides its Contributions) on an "AS IS" BASIS,
146
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147
      implied, including, without limitation, any warranties or conditions
148
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149
      PARTICULAR PURPOSE. You are solely responsible for determining the
150
      appropriateness of using or redistributing the Work and assume any
151
      risks associated with Your exercise of permissions under this License.
152
153
   8. Limitation of Liability. In no event and under no legal theory,
154
      whether in tort (including negligence), contract, or otherwise,
155
      unless required by applicable law (such as deliberate and grossly
156
      negligent acts) or agreed to in writing, shall any Contributor be
157
      liable to You for damages, including any direct, indirect, special,
158
      incidental, or consequential damages of any character arising as a
159
      result of this License or out of the use or inability to use the
160
      Work (including but not limited to damages for loss of goodwill,
161
      work stoppage, computer failure or malfunction, or any and all
162
      other commercial damages or losses), even if such Contributor
163
      has been advised of the possibility of such damages.
164
165
   9. Accepting Warranty or Additional Liability. While redistributing
166
      the Work or Derivative Works thereof, You may choose to offer,
167
      and charge a fee for, acceptance of support, warranty, indemnity,
168
      or other liability obligations and/or rights consistent with this
169
      License. However, in accepting such obligations, You may act only
170
      on Your own behalf and on Your sole responsibility, not on behalf
171
      of any other Contributor, and only if You agree to indemnify,
172
      defend, and hold each Contributor harmless for any liability
173
      incurred by, or claims asserted against, such Contributor by reason
174
      of your accepting any such warranty or additional liability.

 Everyone is permitted to copy and distribute verbatim copies
7
 of this license document, but changing it is not allowed.

			    Preamble
10
11
  The licenses for most software are designed to take away your
12
freedom to share and change it.  By contrast, the GNU General Public
13
License is intended to guarantee your freedom to share and change free
14
software--to make sure the software is free for all its users.  This
15
General Public License applies to most of the Free Software
16
Foundation's software and to any other program whose authors commit to
17
using it.  (Some other Free Software Foundation software is covered by
18
the GNU Library General Public License instead.)  You can apply it to
19
your programs, too.
20
21
  When we speak of free software, we are referring to freedom, not
22
price.  Our General Public Licenses are designed to make sure that you
23
have the freedom to distribute copies of free software (and charge for
24
this service if you wish), that you receive source code or can get it
25
if you want it, that you can change the software or use pieces of it
26
in new free programs; and that you know you can do these things.
27
28
  To protect your rights, we need to make restrictions that forbid
29
anyone to deny you these rights or to ask you to surrender the rights.
30
These restrictions translate to certain responsibilities for you if you
31
distribute copies of the software, or if you modify it.
32
33
  For example, if you distribute copies of such a program, whether
34
gratis or for a fee, you must give the recipients all the rights that
35
you have.  You must make sure that they, too, receive or can get the
36
source code.  And you must show them these terms so they know their
37
rights.
38
39
  We protect your rights with two steps: (1) copyright the software, and
40
(2) offer you this license which gives you legal permission to copy,
41
distribute and/or modify the software.
42
43
  Also, for each author's protection and ours, we want to make certain
44
that everyone understands that there is no warranty for this free
45
software.  If the software is modified by someone else and passed on, we
46
want its recipients to know that what they have is not the original, so
47
that any problems introduced by others will not reflect on the original
48
authors' reputations.
49
50
  Finally, any free program is threatened constantly by software
51
patents.  We wish to avoid the danger that redistributors of a free
52
program will individually obtain patent licenses, in effect making the
53
program proprietary.  To prevent this, we have made it clear that any
54
patent must be licensed for everyone's free use or not licensed at all.
55
56
  The precise terms and conditions for copying, distribution and
57
modification follow.
58

		    GNU GENERAL PUBLIC LICENSE
60
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61
62
  0. This License applies to any program or other work which contains
63
a notice placed by the copyright holder saying it may be distributed
64
under the terms of this General Public License.  The "Program", below,
65
refers to any such program or work, and a "work based on the Program"
66
means either the Program or any derivative work under copyright law:
67
that is to say, a work containing the Program or a portion of it,
68
either verbatim or with modifications and/or translated into another
69
language.  (Hereinafter, translation is included without limitation in
70
the term "modification".)  Each licensee is addressed as "you".
71
72
Activities other than copying, distribution and modification are not
73
covered by this License; they are outside its scope.  The act of
74
running the Program is not restricted, and the output from the Program
75
is covered only if its contents constitute a work based on the
76
Program (independent of having been made by running the Program).
77
Whether that is true depends on what the Program does.
78
79
  1. You may copy and distribute verbatim copies of the Program's
80
source code as you receive it, in any medium, provided that you
81
conspicuously and appropriately publish on each copy an appropriate
82
copyright notice and disclaimer of warranty; keep intact all the
83
notices that refer to this License and to the absence of any warranty;
84
and give any other recipients of the Program a copy of this License
85
along with the Program.
86
87
You may charge a fee for the physical act of transferring a copy, and
88
you may at your option offer warranty protection in exchange for a fee.
89
90
  2. You may modify your copy or copies of the Program or any portion
91
of it, thus forming a work based on the Program, and copy and
92
distribute such modifications or work under the terms of Section 1
93
above, provided that you also meet all of these conditions:
94
95
    a) You must cause the modified files to carry prominent notices
96
    stating that you changed the files and the date of any change.
97
98
    b) You must cause any work that you distribute or publish, that in
99
    whole or in part contains or is derived from the Program or any
100
    part thereof, to be licensed as a whole at no charge to all third
101
    parties under the terms of this License.
102
103
    c) If the modified program normally reads commands interactively
104
    when run, you must cause it, when started running for such
105
    interactive use in the most ordinary way, to print or display an
106
    announcement including an appropriate copyright notice and a
107
    notice that there is no warranty (or else, saying that you provide
108
    a warranty) and that users may redistribute the program under
109
    these conditions, and telling the user how to view a copy of this
110
    License.  (Exception: if the Program itself is interactive but
111
    does not normally print such an announcement, your work based on
112
    the Program is not required to print an announcement.)
113

114
These requirements apply to the modified work as a whole.  If
115
identifiable sections of that work are not derived from the Program,
116
and can be reasonably considered independent and separate works in
117
themselves, then this License, and its terms, do not apply to those
118
sections when you distribute them as separate works.  But when you
119
distribute the same sections as part of a whole which is a work based
120
on the Program, the distribution of the whole must be on the terms of
121
this License, whose permissions for other licensees extend to the
122
entire whole, and thus to each and every part regardless of who wrote it.
123
124
Thus, it is not the intent of this section to claim rights or contest
125
your rights to work written entirely by you; rather, the intent is to
126
exercise the right to control the distribution of derivative or
127
collective works based on the Program.
128
129
In addition, mere aggregation of another work not based on the Program
130
with the Program (or with a work based on the Program) on a volume of
131
a storage or distribution medium does not bring the other work under
132
the scope of this License.
133
134
  3. You may copy and distribute the Program (or a work based on it,
135
under Section 2) in object code or executable form under the terms of
136
Sections 1 and 2 above provided that you also do one of the following:
137
138
    a) Accompany it with the complete corresponding machine-readable
139
    source code, which must be distributed under the terms of Sections
140
    1 and 2 above on a medium customarily used for software interchange; or,
141
142
    b) Accompany it with a written offer, valid for at least three
143
    years, to give any third party, for a charge no more than your
144
    cost of physically performing source distribution, a complete
145
    machine-readable copy of the corresponding source code, to be
146
    distributed under the terms of Sections 1 and 2 above on a medium
147
    customarily used for software interchange; or,
148
149
    c) Accompany it with the information you received as to the offer
150
    to distribute corresponding source code.  (This alternative is
151
    allowed only for noncommercial distribution and only if you
152
    received the program in object code or executable form with such
153
    an offer, in accord with Subsection b above.)
154
155
The source code for a work means the preferred form of the work for
156
making modifications to it.  For an executable work, complete source
157
code means all the source code for all modules it contains, plus any
158
associated interface definition files, plus the scripts used to
159
control compilation and installation of the executable.  However, as a
160
special exception, the source code distributed need not include
161
anything that is normally distributed (in either source or binary
162
form) with the major components (compiler, kernel, and so on) of the
163
operating system on which the executable runs, unless that component
164
itself accompanies the executable.
165
166
If distribution of executable or object code is made by offering
167
access to copy from a designated place, then offering equivalent
168
access to copy the source code from the same place counts as
169
distribution of the source code, even though third parties are not
170
compelled to copy the source along with the object code.
171

172
  4. You may not copy, modify, sublicense, or distribute the Program
173
except as expressly provided under this License.  Any attempt
174
otherwise to copy, modify, sublicense or distribute the Program is
175
void, and will automatically terminate your rights under this License.
176
However, parties who have received copies, or rights, from you under
177
this License will not have their licenses terminated so long as such
178
parties remain in full compliance.
179
180
  5. You are not required to accept this License, since you have not
181
signed it.  However, nothing else grants you permission to modify or
182
distribute the Program or its derivative works.  These actions are
183
prohibited by law if you do not accept this License.  Therefore, by
184
modifying or distributing the Program (or any work based on the
185
Program), you indicate your acceptance of this License to do so, and
186
all its terms and conditions for copying, distributing or modifying
187
the Program or works based on it.
188
189
  6. Each time you redistribute the Program (or any work based on the
190
Program), the recipient automatically receives a license from the
191
original licensor to copy, distribute or modify the Program subject to
192
these terms and conditions.  You may not impose any further
193
restrictions on the recipients' exercise of the rights granted herein.
194
You are not responsible for enforcing compliance by third parties to
195
this License.
196
197
  7. If, as a consequence of a court judgment or allegation of patent
198
infringement or for any other reason (not limited to patent issues),
199
conditions are imposed on you (whether by court order, agreement or
200
otherwise) that contradict the conditions of this License, they do not
201
excuse you from the conditions of this License.  If you cannot
202
distribute so as to satisfy simultaneously your obligations under this
203
License and any other pertinent obligations, then as a consequence you
204
may not distribute the Program at all.  For example, if a patent
205
license would not permit royalty-free redistribution of the Program by
206
all those who receive copies directly or indirectly through you, then
207
the only way you could satisfy both it and this License would be to
208
refrain entirely from distribution of the Program.
209
210
If any portion of this section is held invalid or unenforceable under
211
any particular circumstance, the balance of the section is intended to
212
apply and the section as a whole is intended to apply in other
213
circumstances.
214
215
It is not the purpose of this section to induce you to infringe any
216
patents or other property right claims or to contest validity of any
217
such claims; this section has the sole purpose of protecting the
218
integrity of the free software distribution system, which is
219
implemented by public license practices.  Many people have made
220
generous contributions to the wide range of software distributed
221
through that system in reliance on consistent application of that
222
system; it is up to the author/donor to decide if he or she is willing
223
to distribute software through any other system and a licensee cannot
224
impose that choice.
225
226
This section is intended to make thoroughly clear what is believed to
227
be a consequence of the rest of this License.
228

229
  8. If the distribution and/or use of the Program is restricted in
230
certain countries either by patents or by copyrighted interfaces, the
231
original copyright holder who places the Program under this License
232
may add an explicit geographical distribution limitation excluding
233
those countries, so that distribution is permitted only in or among
234
countries not thus excluded.  In such case, this License incorporates
235
the limitation as if written in the body of this License.
236
237
  9. The Free Software Foundation may publish revised and/or new versions
238
of the General Public License from time to time.  Such new versions will
239
be similar in spirit to the present version, but may differ in detail to
240
address new problems or concerns.
241
242
Each version is given a distinguishing version number.  If the Program
243
specifies a version number of this License which applies to it and "any
244
later version", you have the option of following the terms and conditions
245
either of that version or of any later version published by the Free
246
Software Foundation.  If the Program does not specify a version number of
247
this License, you may choose any version ever published by the Free Software
248
Foundation.
249
250
  10. If you wish to incorporate parts of the Program into other free
251
programs whose distribution conditions are different, write to the author
252
to ask for permission.  For software which is copyrighted by the Free
253
Software Foundation, write to the Free Software Foundation; we sometimes
254
make exceptions for this.  Our decision will be guided by the two goals
255
of preserving the free status of all derivatives of our free software and
256
of promoting the sharing and reuse of software generally.
257
258
			    NO WARRANTY
259
260
  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
262
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
266
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
267
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268
REPAIR OR CORRECTION.
269
270
  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278
POSSIBILITY OF SUCH DAMAGES.
279
280
		     END OF TERMS AND CONDITIONS
281

282
	    How to Apply These Terms to Your New Programs
283
284
  If you develop a new program, and you want it to be of the greatest
285
possible use to the public, the best way to achieve this is to make it
286
free software which everyone can redistribute and change under these terms.
287
288
  To do so, attach the following notices to the program.  It is safest
289
to attach them to the start of each source file to most effectively
290
convey the exclusion of warranty; and each file should have at least
291
the "copyright" line and a pointer to where the full notice is found.
292
293
    <one line to give the program's name and a brief idea of what it does.>
294
    Copyright (C) <year>  <name of author>
295
296
    This program is free software; you can redistribute it and/or modify
297
    it under the terms of the GNU General Public License as published by
298
    the Free Software Foundation; either version 2 of the License, or
299
    (at your option) any later version.
300
301
    This program is distributed in the hope that it will be useful,
302
    but WITHOUT ANY WARRANTY; without even the implied warranty of
303
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
304
    GNU General Public License for more details.
305
306
    You should have received a copy of the GNU General Public License
307
    along with this program; if not, write to the Free Software
308
    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
309
310
311
Also add information on how to contact you by electronic and paper mail.
312
313
If the program is interactive, make it output a short notice like this
314
when it starts in an interactive mode:
315
316
    Gnomovision version 69, Copyright (C) year name of author
317
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
318
    This is free software, and you are welcome to redistribute it
319
    under certain conditions; type `show c' for details.
320
321
The hypothetical commands `show w' and `show c' should show the appropriate
322
parts of the General Public License.  Of course, the commands you use may
323
be called something other than `show w' and `show c'; they could even be
324
mouse-clicks or menu items--whatever suits your program.
325
326
You should also get your employer (if you work as a programmer) or your
327
school, if any, to sign a "copyright disclaimer" for the program, if
328
necessary.  Here is a sample; alter the names:
329
330
  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
331
  `Gnomovision' (which makes passes at compilers) written by James Hacker.

  Ty Coon, President of Vice
335
336
This General Public License does not permit incorporating your program into
337
proprietary programs.  If your program is a subroutine library, you may
338
consider it more useful to permit linking proprietary applications with the
339
library.  If this is what you want to do, use the GNU Library General
340
Public License instead of this License.

105
  2.3. Limitations on Grant Scope
106
107
   The licenses granted in this Section 2 are the only rights granted

   under this License. No additional rights or licenses will be implied
109
   from the distribution or licensing of Covered Software under this
110

111
   granted by a Contributor:
112
    a. for any code that a Contributor has removed from Covered Software;
113
       or

120
121
   This License does not grant any rights in the trademarks, service
122
   marks, or logos of any Contributor (except as may be necessary to
123
   comply with the notice requirements in Section 3.4).
124
125
  2.4. Subsequent Licenses
126
127
   No Contributor makes additional grants as a result of Your choice to
128
   distribute the Covered Software under a subsequent version of this
129
   License (see Section 10.2) or under the terms of a Secondary License
130
   (if permitted under the terms of Section 3.3).
131
132
  2.5. Representation
133
134
   Each Contributor represents that the Contributor believes its
135
   Contributions are its original creation(s) or it has sufficient rights
136
   to grant the rights to its Contributions conveyed by this License.
137
138
  2.6. Fair Use
139
140
   This License is not intended to limit any rights You have under

   equivalents.
143
144
  2.7. Conditions
145
146
   Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
147
   in Section 2.1.
148
149
3. Responsibilities
150
151
  3.1. Distribution of Source Form
152
153
   All distribution of Covered Software in Source Code Form, including any
154
   Modifications that You create or to which You contribute, must be under
155
   the terms of this License. You must inform recipients that the Source
156
   Code Form of the Covered Software is governed by the terms of this
157
   License, and how they can obtain a copy of this License. You may not
158
   attempt to alter or restrict the recipients’ rights in the Source Code
159
   Form.
160
161
  3.2. Distribution of Executable Form
162
163
   If You distribute Covered Software in Executable Form then:
164
    a. such Covered Software must also be made available in Source Code
165
       Form, as described in Section 3.1, and You must inform recipients
166
       of the Executable Form how they can obtain a copy of such Source
167
       Code Form by reasonable means in a timely manner, at a charge no
168
       more than the cost of distribution to the recipient; and
169
    b. You may distribute such Executable Form under the terms of this
170
       License, or sublicense it under different terms, provided that the
171
       license for the Executable Form does not attempt to limit or alter
172
       the recipients’ rights in the Source Code Form under this License.
173
174
  3.3. Distribution of a Larger Work
175
176
   You may create and distribute a Larger Work under terms of Your choice,
177
   provided that You also comply with the requirements of this License for
178
   the Covered Software. If the Larger Work is a combination of Covered
179
   Software with a work governed by one or more Secondary Licenses, and
180
   the Covered Software is not Incompatible With Secondary Licenses, this
181
   License permits You to additionally distribute such Covered Software
182
   under the terms of such Secondary License(s), so that the recipient of
183
   the Larger Work may, at their option, further distribute the Covered
184
   Software under the terms of either this License or such Secondary
185
   License(s).
186
187
  3.4. Notices
188
189
   You may not remove or alter the substance of any license notices
190
   (including copyright notices, patent notices, disclaimers of warranty,
191
   or limitations of liability) contained within the Source Code Form of
192
   the Covered Software, except that You may alter any license notices to
193
   the extent required to remedy known factual inaccuracies.
194
195
  3.5. Application of Additional Terms
196
197
   You may choose to offer, and to charge a fee for, warranty, support,
198
   indemnity or liability obligations to one or more recipients of Covered
199
   Software. However, You may do so only on Your own behalf, and not on
200
   behalf of any Contributor. You must make it absolutely clear that any
201
   such warranty, support, indemnity, or liability obligation is offered
202
   by You alone, and You hereby agree to indemnify every Contributor for
203
   any liability incurred by such Contributor as a result of warranty,
204
   support, indemnity or liability terms You offer. You may include
205
   additional disclaimers of warranty and limitations of liability
206
   specific to any jurisdiction.
207
208
4. Inability to Comply Due to Statute or Regulation
209
210
   If it is impossible for You to comply with any of the terms of this
211
   License with respect to some or all of the Covered Software due to
212
   statute, judicial order, or regulation then You must: (a) comply with
213
   the terms of this License to the maximum extent possible; and (b)
214
   describe the limitations and the code they affect. Such description
215
   must be placed in a text file included with all distributions of the
216
   Covered Software under this License. Except to the extent prohibited by
217
   statute or regulation, such description must be sufficiently detailed
218
   for a recipient of ordinary skill to be able to understand it.
219
220
5. Termination
221
222
   5.1. The rights granted under this License will terminate automatically
223
   if You fail to comply with any of its terms. However, if You become
224
   compliant, then the rights granted under this License from a particular
225
   Contributor are reinstated (a) provisionally, unless and until such
226
   Contributor explicitly and finally terminates Your grants, and (b) on
227
   an ongoing basis, if such Contributor fails to notify You of the
228
   non-compliance by some reasonable means prior to 60 days after You have
229
   come back into compliance. Moreover, Your grants from a particular
230
   Contributor are reinstated on an ongoing basis if such Contributor
231
   notifies You of the non-compliance by some reasonable means, this is
232
   the first time You have received notice of non-compliance with this
233
   License from such Contributor, and You become compliant prior to 30
234
   days after Your receipt of the notice.
235
236
   5.2. If You initiate litigation against any entity by asserting a
237
   patent infringement claim (excluding declaratory judgment actions,
238
   counter-claims, and cross-claims) alleging that a Contributor Version
239
   directly or indirectly infringes any patent, then the rights granted to
240
   You by any and all Contributors for the Covered Software under
241
   Section 2.1 of this License shall terminate.
242
243
   5.3. In the event of termination under Sections 5.1 or 5.2 above, all
244
   end user license agreements (excluding distributors and resellers)
245
   which have been validly granted by You or Your distributors under this
246
   License prior to termination shall survive termination.
247
248
6. Disclaimer of Warranty
249
250
   Covered Software is provided under this License on an “as is” basis,
251
   without warranty of any kind, either expressed, implied, or statutory,
252
   including, without limitation, warranties that the Covered Software is
253
   free of defects, merchantable, fit for a particular purpose or
254
   non-infringing. The entire risk as to the quality and performance of
255
   the Covered Software is with You. Should any Covered Software prove
256
   defective in any respect, You (not any Contributor) assume the cost of
257
   any necessary servicing, repair, or correction. This disclaimer of
258
   warranty constitutes an essential part of this License. No use of any
259
   Covered Software is authorized under this License except under this
260
   disclaimer.
261
262
7. Limitation of Liability
263
264
   Under no circumstances and under no legal theory, whether tort
265
   (including negligence), contract, or otherwise, shall any Contributor,
266
   or anyone who distributes Covered Software as permitted above, be
267
   liable to You for any direct, indirect, special, incidental, or
268
   consequential damages of any character including, without limitation,
269
   damages for lost profits, loss of goodwill, work stoppage, computer
270
   failure or malfunction, or any and all other commercial damages or
271
   losses, even if such party shall have been informed of the possibility
272
   of such damages. This limitation of liability shall not apply to
273
   liability for death or personal injury resulting from such party’s
274
   negligence to the extent applicable law prohibits such limitation. Some
275
   jurisdictions do not allow the exclusion or limitation of incidental or
276
   consequential damages, so this exclusion and limitation may not apply
277
   to You.
278
279
8. Litigation
280
281
   Any litigation relating to this License may be brought only in the
282
   courts of a jurisdiction where the defendant maintains its principal
283
   place of business and such litigation shall be governed by laws of that
284
   jurisdiction, without reference to its conflict-of-law provisions.
285
   Nothing in this Section shall prevent a party’s ability to bring
286
   cross-claims or counter-claims.
287
288
9. Miscellaneous
289
290
   This License represents the complete agreement concerning the subject
291
   matter hereof. If any provision of this License is held to be
292
   unenforceable, such provision shall be reformed only to the extent
293
   necessary to make it enforceable. Any law or regulation which provides
294
   that the language of a contract shall be construed against the drafter
295
   shall not be used to construe this License against a Contributor.
296
297
10. Versions of the License
298
299
  10.1. New Versions
300
301
   Mozilla Foundation is the license steward. Except as provided in
302
   Section 10.3, no one other than the license steward has the right to
303
   modify or publish new versions of this License. Each version will be
304
   given a distinguishing version number.
305
306
  10.2. Effect of New Versions
307
308
   You may distribute the Covered Software under the terms of the version
309
   of the License under which You originally received the Covered
310
   Software, or under the terms of any subsequent version published by the
311
   license steward.
312
313
  10.3. Modified Versions
314
315
   If you create software not governed by this License, and you want to
316
   create a new license for such software, you may create and use a
317
   modified version of this License if you rename the license and remove
318
   any references to the name of the license steward (except to note that
319
   such modified license differs from this License).
320
321
  10.4. Distributing Source Code Form that is Incompatible With Secondary
322
  Licenses
323
324
   If You choose to distribute Source Code Form that is Incompatible With
325
   Secondary Licenses under the terms of this version of the License, the
326
   notice described in Exhibit B of this License must be attached.
327
328
Exhibit A - Source Code Form License Notice
329
330
     This Source Code Form is subject to the terms of the Mozilla Public
331
     License, v. 2.0. If a copy of the MPL was not distributed with this
332
     file, You can obtain one at https://mozilla.org/MPL/2.0/.
333
334
   If it is not possible or desirable to put the notice in a particular
335
   file, then You may include the notice in a location (such as a LICENSE
336
   file in a relevant directory) where a recipient would be likely to look
337
   for such a notice.
338
339
   You may add additional accurate notices of copyright ownership.
340
341
Exhibit B - “Incompatible With Secondary Licenses” Notice

PREAMBLE
13
The goals of the Open Font License (OFL) are to stimulate worldwide
14
development of collaborative font projects, to support the font creation
15
efforts of academic and linguistic communities, and to provide a free and
16
open framework in which fonts may be shared and improved in partnership
17
with others.
18
19
The OFL allows the licensed fonts to be used, studied, modified and
20
redistributed freely as long as they are not sold by themselves. The
21
fonts, including any derivative works, can be bundled, embedded,
22
redistributed and/or sold with any software provided that any reserved
23
names are not used by derivative works. The fonts and derivatives,
24
however, cannot be released under any other type of license. The
25
requirement for fonts to remain under this license does not apply
26
to any document created using the fonts or their derivatives.
27

PREAMBLE
13
The goals of the Open Font License (OFL) are to stimulate worldwide

open framework in which fonts may be shared and improved in partnership
17
with others.
18
19
The OFL allows the licensed fonts to be used, studied, modified and
20
redistributed freely as long as they are not sold by themselves. The
21
fonts, including any derivative works, can be bundled, embedded, 
22
redistributed and/or sold with any software provided that any reserved
23
names are not used by derivative works. The fonts and derivatives,
24
however, cannot be released under any other type of license. The
25
requirement for fonts to remain under this license does not apply
26
to any document created using the fonts or their derivatives.

# R Scripts
2
3
These R scripts illustrate how R can be used within an application to perform calculations using variables. Authors are free to write their own scripts, of course. These scripts serve as an example of how to automate certain tasks while writing.
4
5
## Configuration
6
7
Configure the editor to use the R scripts as follows:
8
9
1. Copy the R scripts into same directory as your Markdown files.
10
1. Start the editor.
11
1. Click **Tools → R Script**.
12
1. Copy and paste the following:
13
14
        assign( 'anchor', as.Date( '$date.anchor$', format='%Y-%m-%d' ), envir = .GlobalEnv );
15
        setwd( '$application.r.working.directory$' );
16
        source( 'pluralize.R' );
17
        source( 'csv.R' );
18
        source( 'conversion.R' );
19
20
1. Click **File → New** to create a new file.
21
1. Click **File → Save As** to set a filename.
22
1. Set **Name** to: `variables.yaml`

25
26
        date:
27
          anchor: 2017-01-01
28
        editor:
29
          examples:
30
            season: 2017-09-02
31
            math:
32
              x: 1
33
              y: $editor.examples.math.x$ + 1
34
              z: $editor.examples.math.y$ + 1
35
            name:
36
              given: Josephene
37
38
1. Save and close the file.
39
1. Click **File → Open**
40
1. Change **Markdown Files** to **Definition Files**.
41

45
46
## Definitions
47
48
The variables definitions within `variables.yaml` are available to R using the R syntax. An additional variable, `application.r.working.directory` is added to the list of variables. The value is set to the working directory of the file being edited. Hover the mouse cursor over the file tab in the editor to see the full path to the file.
49
50
## Examples
51
52
This section demonstrates how to use the R functions when editing. Complete the following steps to begin:
53
54
1. Click **File → New** to create a new file.
55
1. Click **File → Save As** to set a filename.
56
1. Set **Name** to: `example.Rmd`
57
1. Click **OK**.
58
59

60
61
### Arithmetic
62
63
Type the following to perform a simple calculation:
64
65
    `r# 1+1`
66
67
The preview pane shows `2.0`.
68
69
### Functions
70
71
Call the [format](https://stat.ethz.ch/R-manual/R-devel/library/base/html/format.html) function to truncate unwanted decimal places as follows:
72
73
    `r# format(1+1,digits=1)`
74
75
The preview pane shows `2`.
76
77
### Pluralize
78
79
Many English words can be pluralized as follows:
80
81
    `r# pl('wolf',2)`
82
83
The preview pane shows `wolves`. The `pluralize.R` file contains a partial implementation of Damian Conway's algorithmic approach to English pluralization.
84
85
### Chicago Manual of Style
86
87
Apply the Chicago Manual of Style for words less than one-hundred as follows:
88
89
       `r# cms(1)` `r# cms(99)` `r# cms(101)`
90
91
The preview pane shows numbers written out as `one` and `ninety-nine`, followed by the digits 101.
92
93
### Data Import
94
95
Import and display information from a CSV file as follows:
96
97
1. Click **File → New** to create a new file.
98
1. Click **File → Save As** to rename the file.
99
1. Set the filename to: `data.csv`
100
1. Paste the following into `data.csv`:
101
102
        Animal,Quantity,Country
103
        Aardwolf,1,Africa
104
        Keel-billed toucan,1,Belize
105
        Beaver,2,Canada
106
        Mute swan,3,Denmark
107
        Lion,5,Ethiopia
108
        Brown bear,8,Finland
109
        Dolphin,13,Greece
110
        Turul,21,Hungary
111
        Gyrfalcon,34,Iceland
112
        Red-billed streamertail,55,Jamaica
113
114
1. Click the `example.Rmd` tab.
115
1. Type the following:
116
117
       `r# csv2md('data.csv',total=F)`
118
119
1. Type the following to calculate a total for all numeric columns:
120
121
       `r# csv2md('data.csv')`
122
123
This imports the data from an external file and formats the information into a table, automatically. Update the data as follows:
124
125
1. Click the `data.csv` tab to edit the data.
126
1. Change the data by adding a new row.
127
1. Save the file.
128
1. Click the `example.Rmd` tab.
129
130
The preview pane shows the revised contents.
131
132
### Elapsed Time
133
134
The duration of a timeline, given in numbers of days, can be computed into English as follows:
135
136
    `r# elapsed(1,1)`
137
138
The preview pane shows `same day`. Change the expression to:
139
140
    `r# elapsed(1,2)`
141
142
The preview pane shows `one day`. Change the expression to:
143
144
    `r# elapsed(1,112358)`
145
146
The preview pane shows `307 years, seven months, and sixteen days`, combined using the Chicago Manual of Style, the pluralization function, and a [serial comma](https://www.behance.net/gallery/19417363/The-Oxford-Comma).
147
148
### Variable Syntax
149
150
The syntax for a variable changes when using an R Markdown file (denoted by the `.Rmd` filename extension), as opposed to a regular Markdown file (`.md`). Return to the example file and type the following:
151
152
    `r# v$date$anchor`
153
154
The preview pane shows the date.
155
156
### Autocomplete
157
158
Automatically insert a variable reference into the text as follows:
159
160
1. Type: `Jos`
161
    * Note the capital letter, matches are case sensitive.
162
1. Hold down the `Control` key.
163
1. Tap the `Spacebar`
164
165
The editor shows:
166
167
    `r#x( v$editor$examples$name$given )`
168
169
The preview pane shows:
170
171
    Josephine
172
173
Here, the `x` function evaluates its parameter as an expression. This allows variables to include expressions in their definition.
174
175
### Variable Definition Expressions
176
177
Definition file variables are have the ability to reference other definitions. Try the following:
178
179
    x = `r#x( v$editor$examples$math$x )`;
180
    y = `r#x( v$editor$examples$math$y )`;
181
    z = `r#x( v$editor$examples$math$z )`
182
183
The preview pane shows:
184
185
    x = 1.0; y = 2.0; z = 3.0
186
187
### Case
188
189
Ensure words begin with a lowercase letter as follows:
190
191
    `r#lc( v$editor$examples$name$given )`
192
193
The preview pane shows:
194
195
    josephine
196
197
Similarly, ensure an uppercase letter as follows:
198
199
    `r#uc( 'hello, world!' )`
200
201
The preview pane shows:
202
203
    Hello, world!
204
205
### Month
206
207
Display the month name given a month number as follows:
208
209
    `r# month( 1 )`
210
211
The preview pane shows:
212
213
    January
214
215
## Summary
216
217
Authors can inline R statements into documents, directly, so long as those statements generate text. Plots, graphs, and images must be referenced as external image files or URLs.

The lexicon files are retrieved from SymSpell in the parent directory:

svn export \

  https://github.com/wolfgarbe/SymSpell/trunk/SymSpell.FrequencyDictionary/ lexicons

The lexicons and bigrams are both space-separated, but parsing a
9
tab-delimited file is easier, so change them to tab-separated files.
