How do I implement a pre-commit hook script in SVN that calls dos2unix to validate checked-in file
I was wondering if anyone here had some experience writing this type of script and if they could give me some pointers.
I would like to modify this script to validate that the check-in file does not have a Carriage Return in the EOL formatting. The EOL format is CR LF in Windows and LF in Unix. When a User checks-in code with the Windows format. It does not compile in Unix anymore. I know this can be done on the client side but I need to have this validation done on the server side. To achieve this, I need to do the following:
1) Make sure the file I check is not a binary, I dont know how to do this with svnlook, should I check the mime:type of the file? The Red Book does not indicate this clearly or I must have not seen it.
2) I would like to run the dos2unix command to validate that the file has the correct EOL format. I would compare the output of the dos2unix command against the original file. If there is a diff between both, I give an error message to the client and cancel the check-in.
I would like your comments/feedback on this approach.

I think you can avoid a commit hook script in this case by using the
svn:eol-style property as described in the SVNBook:
This way SVN can worry about your line endings for you.

What exactly are you trying to do?
Of course, there are numerous places to learn about svn pre-commit hooks (e.g. here , here, and in the Red Book) but it depends what you're trying to do and what is available on your system.
Can you be more specific?Answered by: Sawyer374 | Posted: 01-03-2022
