Precommit hook for svn to modify files to be committed in c#

Question

I want to modify in certain way(Actually format the files in a code formatter) before they are committed to repository. I have found out from Precommit example (Use guest as name and no password) how to write in python.But what i want to know is how to get list of files to be committed and other command line arguments this one takes.One more thing i prefer is to write my own pre commit hook in C# rather than Python or any other script.

Few points I will write a exe which will format,but i want the list of files being committed How to configure this with svn.

Answer 1

Precommit hooks that modify the committed files are considered 'a bad thing':

http://svnbook.red-bean.com/en/1.5/svn.reposadmin.create.html#svn.reposadmin.create.hooks

The idea merits a big red box in the official SVN documentation, and warns that this will affect how the SVN client works with the repository in bad ways.

Answer 2

The first parameter passed to the pre-commit hook script is a path to a text file. That text file contains all the paths which are to be committed, separated by newlines.

But for your situation, you might better use the start-commit hook: that script is called right before the commit begins, but after the user selected the files/folders to commit. The start-commit script is called after the user clicks OK in the commit dialog, and before the actual commit begins. This hook has a list of exactly what will be committed.
