Our company's workflow requires that our P4 check-in messages have a specific format. A helpful feature in the GIT-P4 program would be a hook that occurs after the P4 change list is created but before it is displayed in the editor that would allow an external program to possibly edit the changelist text. v1:My suggestion for the hook name is p4-pre-edit-changelist. It would take a single parameter, the full path of the temporary file. If the hook returns a non-zero exit code, it would cancel the current P4 submit. The hook should be optional. v2:Instead of a single hook, p4-pre-edit-changelist, follow the git convention for hook names and add the trio of hooks that work together, similar to git commit. The hook names are: * p4-prepare-changelist * p4-changelist * p4-post-changelist The hooks should follow the same convention as git commit, so a new command line option for the git-p4 submit function --no-verify should also be added. v3:2-Feb-2020 This version reorganizes the commits to be easier to read. The function for running the git hook has been rewritten to include suggestions. This version no longer restricts the executable supported by windows for the hook. It will first look for a file with the hook name without an extension and if found, it will pass it to sh.exe (Git for Window's MINGW shell) Otherwise it will take the file with the lowest alphabetical extension and ask Windows to execute the program.
