It lets you maintain a single set of documentation as a [[TiddlyWikiFolder|TiddlyWikiFolders]] containing separate tiddler files under source code control, and then use it to produce `readme.md` files for inclusion in project folders, or HTML files for storage in [[GitHub Pages|http://pages.github.com/]]. Both features are demonstrated by TiddlyWiki5 itself. ! Generating `readme.md` files When displaying the contents of a folder GitHub will look for a `readme.md` file and display it. Note that it will not display full HTML files in this way, just static MarkDown files (this is a security measure). Happily MarkDown permits a safe subset of HTML, and thus to generate a `readme.md` file that is suitable for GitHub it is just necessary for TiddlyWiki5 to generate the content of the `` element of an HTML document, and give it the appropriate filename. This is done in `bin/bld.sh` by this command: ``` --rendertiddler ReadMe ./readme.md text/html ``` It saves the tiddler ReadMe to the file `./readme.md` in the `text/html` format. By default, tiddler links will be rendered as `` links to a relative URI consisting of the title of the tiddler. This behaviour can be overridden by defining the macro `tv-wikilink-template`, as is done at the top of the tiddler ReadMe: ``` \define tv-wikilink-template() http://tiddlywiki.com/static/$uri_doubleencoded$.html ``` See the LinkWidget for more details. In this example, tiddler links are rendered as links to the static rendering of tw5.com. ! Publishing to GitHub Pages Publishing to GitHub Pages is very straightforward. In the case of TiddlyWiki5, several different build products are published. The `bld.sh` script deposits the build products directly into the local clone of the repo associated with the GitHub Pages account. There is then a manual step to review changes and push them up to github.com.
