PublishAddOn
History
This Addon started as the TWiki:Plugins/GenHTMLAddon, submitted by TWiki:Main/MartinRaabe at Motorola. This version is a major rewrite from TWiki:Main/EricScouten.
Usage
When TWiki generates a view, it does so dynamically i.e. there's a CGI script that runs, processes some files, and generates HTML that is displayed by the browser. There are circumstances in which this may not be desirable or even possible. For example:
- TWiki is used to create documentation which has to be bundled into a product release,
- Published versions of TWiki pages must be read-only,
- The TWiki server is inaccessible to the audience (e.g. on the other side of a corporate firewall).
PublishAddon? provides support for the generation of stand-alone HTML from a TWiki web. It will generate a directory containing rendered versions of a set of TWiki pages together with any attached files.
WARNING This addon generates HTML output in the 'pub' directories of your twiki installation. For a large web, this can amount to a considerable amount of data!
Features
Tags
- All standard TWiki tags are interpreted, including Plugins
- UnresolvedLinks? to non-existant topics are silently ignored
- Topic links internal to the web are translated to relative links
- External links (outside this web) are left untouched
- Any links to the 'pub' areas of topics in the web are automatically resolved and the referenced files copied into the 'images' subdirectory.
- A specific section of a template or page may be omitted from the rendered HTML by wrapping it in <nopublish> ... </nopublish>. (Hint: Wrap the "control panel" of a template -- the portion that provides edit/attach/etc. in <nopublish>.)
Using the Addon
To generate HTML for a web, view any topic in the web. Edit the URL of the topic and change 'view' to 'publish'. (Hint: Create a WebPublish topic in your web that does this for you.) For example, if you are viewing the WebHome? topic, the URL will be something like
http://node.company.com/twiki/bin/view/Main/WebHome
Modify this URL to read instead
http://node.company.com/twiki/bin/publish/Main/WebHome
(Your TWiki administrator may have already set up a shortcut in the view template; see your local site information for details)
Then hit return to invoke the script.
The first thing you see is a web form that allows you to control the HTML generation for the web. From this form you can change the web to generate documentation for, and list perl regular expressions to match topics that you wish to include (default: all) or exclude from generation. When you have set these parameters appropriately, hit the "Publish" button. Note: You can bypass this screen by adding the option goAhead=yes in the query string.
The HTML is generated in a designated directory for the web; the progress messages printed during documentation generation indicate where the generated HTML has been written.
Specialised templates
Unlike the TWiki:Plugins/GenHTMLAddOn, this addon renders using existing skins. It will, by default, use the skin specified in WebPreferences for the published web. This can be overriden by adding the option skin={skin name} in the query string (same as the view script).
Known problems
- Doesn't handle revision info tags in templates
- Plugin tags that create complex HTML (sug as TWikiDraw? DRAWING tags) are not handled correctly.
- Links to excluded topics get generated as links
