View source for Subversion Input Filters

Subversion allows filtering of files that are commited allowing to verfiy validity of certain things. This can be used to do the commit checks for tabs, new-lines, ...

To enable this feature, create a file:

 /path/to/subversion/tree/hooks/pre-commit

There should already be already directory hooks with several files in them.

I used python to write a pre-commit hook, but in general you can use anything.

In the script, the first argument is repository (REPOS) and the second number is a transaction number (TXN). With these two arguments, you can call command svnlook. For example:

  svnlook command -t "TXN" "REPOS" args

Some commands are:

* log - Get log information (this is comment given when doing commit)
* author - Get author information
* changed - List of files that were changed
* dirs-changed - List of directories that changed
* date - Time of commit
* diff - List of changes in diff format
* info - Get all the information about the commit (but diff)
* cat - Display the file after the change
* history - Display the history
* tree - Display the tree hierarchy
