Currently it makes a +simple HTML export of the Commentary and all the docstrings in a +file. It is meant to be used as a batch operation, like so: + +: emacs -batch -l edocs.el -f edocs-generate-batch file.el + +Each paragraph of text is exported using `org-mode', currently +requiring at least org version 8. + +There is `edocs-generate' which can be used to generate a buffer of +the HTML output of the module it's run in interactively, but it is +not meant as the main entry-point for edocs. The function +`edocs-generate-batch' is the main entry-point of edocs, it is +supposed to be run as a batch procedure as shown above. + +== API + +-- Variable: edocs-stylesheet-location + +The location of the CSS used by the exported HTML. + +By default it uses `style.css'. This can be changed to any value +which can be used as the `href' attribute of a `style' tag as it +is placed verbatim in one. + +-- Variable: edocs-generate-only-body + +Whether to generate only the body and no header/footer info. + +In case the output of edocs is to be embedded into some other +HTML or similar file this option can be changed so that no HTML +header of footer tags are output. Any non-nil value will +suppress these tags. The default is nil. + +-- Variable: edocs-private-regexp + +Regular expression to identify private parts of a module's API. + +Some modules (such as this one) differentiate between public and +private parts of the API. This regular expression is used to +identify symbols that are supposed to be private to the module, +and are not meant to be used outside the module. The default is +`--', which matches any symbol with two hyphens such as +`edocs--symbol-type-map'. + +-- Variable: edocs-exporter + +The exporter to use when exporting docs. + +-- Class: edocs-ascii-exporter + +An exporter that produces ascii text. + +-- Class: edocs-html-exporter + +An exporter that produces html text. + +-- Function: edocs-generate (&optional exporter) + +Generate nice-looking documentation for a module or file. + +Markup is handled by `org-mode' exporting functions. This +command is used both as an interactive command to test the output +of this module and called by the `edocs-generate-batch' function +to generate the actual output. This command outputs its result +into a buffer called `*edocs*' and switches to that buffer. + +-- Function: edocs-generate-batch () + +Generate module docs as a batch operation. + +This function maps over `command-line-args-left' and tries to +export the documentation for each file to a file with the same +name, except for the extension replaced with `.html'. This +function uses the `edocs-generate' command to actually generate +the HTML. + +Options which affect the export of module documentation (such as +`edocs-stylesheet-location') can be changed using the `-eval' +command line argument to Emacs. For example: + +: emacs -batch -l edocs.el -eval "(setq edocs-generate-only-body t)" \ +: -f edocs-generate-batch file.el + -- cgit v1.2.3-54-g00ecf
