The following list is in approximately my order of implementation intention. Any comments or other suggestion are welcome at gnustavo AT cpan.org.
Gerrit is a "web based code review and project management tool for Git based projects" (https://code.google.com/p/gerrit/). It's based on JGit (http://eclipse.org/jgit/) which, as of 2012-01-14, still doesn't support git's standard hooks.
But Gerrit has its own hook infrastructure and we should support it (http://gerrit-documentation.googlecode.com/svn/Documentation/2.5.1/config-hooks.html).
The two hooks that seem to be relevant to Git::Hooks's plugins are patchset-created and ref-updated.
Currently we abort the build on
Use Locale::TextDomain to internationalize it.
As a first job after i18n I intend to nationalize it to Brazilian Portuguese.
Let the user tell which configuration files Git::Hooks should consider.
Currently it considers the three default ones (system,
without knowing which one sets what.
Perhaps we could have a new option
githooks.extra_config that could be set with an array of filenames to invoke
git config --file with in succession.
if set in the default configuration files,
could tell Git::Hooks to grok an extra set of configuration from specific files.
Along the lines of NFSv4 ACLs (http://tools.ietf.org/html/rfc5661#section-6). I'm thinking about prefixing the what component with a '!'.
In http://search.cpan.org/dist/SVN-Hooks/. Currently we're missing DenyFilenames and UpdateConfFile. Actually, I'm thinking that UpdateConfFile is too much specific. Perhaps something along the lines of this post-update hook would be more interesting: http://stackoverflow.com/questions/279169/deploy-a-project-using-git-push.
CheckLog.spelling should have a way to register stop words.
I'd have to ask for a change in Text::SpellChecker.
The Gerrit default
commit-msg implements some checks that could be used here.
Some other things to check:
Some people (e.g. Linus Torvalds) prefer spaces, others prefer tabs.
Some people prefer tab size at 8 characters, others prefer at 4.
This plugin should be able to check these preferences for selected types of files. Some configuration would be like this:
By default any kind of white-space should be allowed. But one could specify tab for tabs only or space for space only.
Note that this checks only the indentation space in each line.
This multi-valued option defines the files that should be checked. By default, no file is checked.
By default trailing white space is denied. But one should be able to allow it.
This way, the options are fixed for any file. Would it be desirable to have different options for different kind of files?
Implement a hook to make it easy to perform some checks on added/modified files. For instance, Perl files should be syntax checked. This could be configured somewhat like this:
CheckFile.rule "\.p[lm]$ perl -c"
The first 'word' in the value would be a regexp used to match the files we're interested in. All that follows would be a command to which the filename would be passed.
This would allow for all kinds of checks specific for some kinds of files. Some interesting ideas here: http://tech.yipit.com/2011/11/16/183772396/.
