mdplayscript
An extension of Markdown for play scripts
This crate is a parser of an extension of Markdown for stage play scripts.
It defines an extended grammar of texts in paragraphs.
It is implemented as a filter for struct Parser of pulldown-cmark crate.
The goal of this parser is to emit an HTML document.
Thus it is recommended to pass the parser to pulldown_cmark::html::push_html or write_html.
This crate has an implementation of mdbook preprocessor: mdbook-playscript.
Example
Play Script Format
A line starts with a string and a right angle denotes a character’s speech. The text before the right angle is the character name and the text after the right angle is the speech of the character.
A> Hello!A text between a pair of parentheses in a speech is the content of a direction.
A> Hello! (some direction)A direction can be placed after the character name. No space is allowed between the right parenthesis and the right angle.
A (running)> Hello!Directives
Directives are written as HTML comments. There are four directives:
- playscript-on
- playscript-off
- playscript-monologue-begin
- playscript-monologue-end
<!-- playscript-on --> and <!-- playscript-off --> switch the parser on and off
respectively.
Monologues are surrounded by the directives: <!-- playscript-monologue-begin -->
and <!-- playscript-monologue-end -->.
The texts surrounded by the monologue directives are styled in the normal font style and the
directions between the directives are styled in italic.
Other forms of texts are handled as normal paragraphs.
The examples above are converted into the following HTML:
use pulldown_cmark::Parser;
use pulldown_cmark::html::push_html;
use mdplayscript::MdPlayScript;
fn convert(s: &str) -> String {
let p = MdPlayScript::new(Parser::new(s));
let mut buf = String::new();
push_html(&mut buf, p);
buf
}
assert_eq!(convert("A> Hello!"),
r##"<div class="speech"><h5 id="D0"><a class="header" href="#D0"><span class="character">A</span></a></h5><p><span>Hello!</span></p></div>
"##);
assert_eq!(convert("A> Hello! (some direction)"),
r##"<div class="speech"><h5 id="D0"><a class="header" href="#D0"><span class="character">A</span></a></h5><p><span>Hello!</span><span class="direction">some direction</span></p></div>
"##);
assert_eq!(convert("A (running)> Hello!"),
r##"<div class="speech"><h5 id="D0"><a class="header" href="#D0"><span class="character">A</span><span class="direction">running</span></a></h5><p><span>Hello!</span></p></div>
"##);
assert_eq!(convert(r#"<!-- playscript-monologue-begin -->
Monologue
(direction)
<!-- playscript-monologue-end -->
"#),
r#"<!-- playscript-monologue-begin -->
<div class="speech"><p><span>Monologue</span><span class="direction">direction</span></p></div><!-- playscript-monologue-end -->
"#);CLI Program
This crate has no proper CLI program. It only has a tiny example program: examples/single.rs.
It converts a single Markdown into an HTML document.
The generated document has a link element which specifies a style sheet examples/play.css.
I prepared an example input file: examples/figaro.md.
The output file is
public/figaro.html.
For Japanese play scripts, I prepared a style sheet examples/play_ja.css.
If you pass -l ja option to examples/single.rs, it uses the style sheet
examples/play_ja.css.
The output file is
public/yushima.html.
Test Code
tests/generate_examples.rs converts example markdown files located in examples directory into HTML files created in the same directory.
ToDo
- Refactor test codes
