//! Tweep is a parser for the Twee 3 interactive fiction format //! //! # What is Twee? //! Twee is "a text format for marking up the source code of Twine stories." It //! is an alternate way to produce interactive fiction stories for the [Twine 2] //! platform, using plain text files instead of a graphical environment. The //! specification for Twee 3, supported by tweep, can be found [here] //! //! # Goals //! The goal of tweep is to provide a fully standards-compliant Twee 3 parser //! that provides helpful warning and error messages for bad practices and //! common mistakes, which can be used as a backend for a compiler as well as //! other novel applications of the Twee 3 format. //! //! # What it's not //! * A compiler - while a corresponding compiler front end is in the works, //! this is not it. tweep only produces rust objects, not html //! * A Twee v1 or v2 parser - currently, there are no plans for supporting any //! version of the Twee specification other than Twee 3 //! //! # Getting started //! To use tweep in your Rust project, simply add the following to your //! Cargo.toml: //! //! ```toml //! [dependencies] //! tweep = "0.2" //! ``` //! //! For basic parsing, the main entry point into tweep is through the [`Story`] //! struct, which provides utility methods for parsing out a complete story from //! a `String` or a `Path` representing a file or directory. When given a //! directory, tweep will parse all files ending in `.tw` or `.twee` and merge //! them into a single output story. For more advanced parsing, such as if the //! tags or metadata attached to a special passage is needed, [`StoryPassages`] //! provides the same interface, but provides [`Passage`] objects in places //! where usually unnecessary information is stripped out. //! //! # Examples //! ``` //! use tweep::Story; //! let input = r#":: StoryTitle //!RustDoc Sample Story //! //!:: StoryData //!{ //! "ifid": "D674C58C-DEFA-4F70-B7A2-27742230C0FC", //! "format": "SugarCube", //! "format-version": "2.28.2", //! "start": "My Starting Passage", //! "tag-colors": { //! "tag1": "green", //! "tag2": "red", //! "tag3": "blue" //! }, //! "zoom": 0.25 //!} //! //!:: My Starting Passage [ tag1 tag2 ] //!This is the starting passage, specified by the start attribute of StoryData. //!Alternately, we could remove that attribute and rename the passage to Start. //! //!It has tags and links to: //! [[Another passage]] //! [[Here too!|Another passage]] //! [[A third passage<-And a different passage]] //! //!:: Another passage {"position":"600,400","size":"100,200"} //!This passage has some metadata attached to it //! //!:: A third passage [tag3] { "position": "400,600" } //!This passage has both tags and metadata. The size attribute of the metadata //!isn't overridden, so it will be set to the default value. //!"#.to_string(); //! //!// Parse the input into an Output<Result<Story, ErrorList>> //!let out = Story::from_string(input); //!assert!(!out.has_warnings()); //! //!// Move the Result out of the Output //!let (res, _) = out.take(); //!assert!(res.is_ok()); //! //!// Get the Story object //!let story = res.ok().unwrap(); //! //!// StoryTitle and StoryData contents are parsed into special fields //!assert_eq!(story.title.unwrap(), "RustDoc Sample Story"); //!assert_eq!(story.data.unwrap().ifid, "D674C58C-DEFA-4F70-B7A2-27742230C0FC"); //! //!// Other passages are parsed into a map, keyed by the passage name //!assert_eq!(story.passages["My Starting Passage"].tags(), &vec!["tag1", "tag2"]); //!let metadata = story.passages["A third passage"].metadata(); //!assert_eq!(metadata["size"], "100,100"); //!assert_eq!(metadata["position"], "400,600"); //! ``` //! //!
