Dist::Zilla::Plugin::FileKeywords - expand $$Keywords$$ in your files.
This plugin is a file_munger. It processes a list of files (by default all files in the distribution) and replaces all occurances of known keywords with their expansions.
It does this is in a manner similar to how Subversion manages keywords. In particular it looks for keywords in the forms:
$$KEYWORD$$ $$KEYWORD: Stuff $$ $$KEYWORD:: Stuff $$ $$:KEYWORD$$ $$:KEYWORD: Stuff $$ $$:KEYWORD:: Stuff $$
Keywords are matched in a case-sensitive manner and only constructs containing defined keywords are modified. If no colon follows the opening '$$' delimeters then the text between the two '$$' delimeters are replaced with the Keyword, one or more colons (:) and the expansion of the keyword, with a space on either side.
In the first two cases a single colon and space follows the keyword and the full expansion appears, however long, followed by a space and the closing '$$' delimeter. If the expansion should contain '$$' by any chance, it will be expanded as '\$\$'.
In the third case a pair of colons and a space follows the keyword and the expansion is truncated, if necessary, so the final construct is no bigger (in characters) than what it replaces. If it is necessary to truncate the expansion, then the final character before the closing delimeter will be a hatch (#) rather than a space.
When a colon follows the opening delimeter, then the entire text of the keyword form, including the delimeters, is replaced by the keyword expansion. In the final version, where there are two colons, the keyword expansion is padded with spaces, or truncated, to occupy the exact same number of characters as the form that is being replaced. Note that in the case of truncation, no '#' will be provided.
Actual keywords are defined in plugins in the Dist::Zilla::Plugin::FileKeywords:: namespace. Currently the only plugin is Dist::Zilla::Plugin::FileKeywords::Standard and the only two keywords it defines are Version (equal to dzil's idea of the current version number) and Distribution (always equal to 'unknown' for now).
plugins need to be loaded with one or more 'plugin' arguments that list a plugin name, optionally followed by a list of keywords in parens.
plugins = Standard(Version Distribution) Weird(Chicken) plugins = Weirder
Currently all keywords in all mentioned plugins are made active. In the future more plugins will appear and some of the stubs for dealing with which sets of plugins/keywords are active will be made to actually do something.
One can also control which files get processed by using the 'include' and 'exclude' file regular expressions. All files are processed that match an include regex and do not match any exclude regexes.
