git-commit-hook

configureable git commit hook

1. Install

Downlod the binary, put it into a folder of your $PATH (for example. /usr/local/bin).

Ensure your user has execution permissions on that file.

2. Configure

There are several places you can put the configuration.

Create a config file named git-commit-hook.yaml.

Create the configuration below your user folder:

/home/user/.config/git-commit-hook

 "project xyz":
   # path to the git repository
   path: "/home/nils/projects/xyz/.git"

   # define types of branch and a pattern to identify the type for the current branch you are working on
   branch:
      master: "^(origin\\/)*master"

   # define a commit message template per branch type, or as here for all (*) branch types
   template:
     "*": "{.BranchName}: {.CommitMessage}"

   # define validation rules per branch type
   validation:
      master:
        "^.*(#\\d*)+.*$" : must have a ticket reference (eg. #267)

3. Activate

Use the subcommand install to activate the commit-message-hook in your repository.

Sub-Commands

There are some useful subcommands which ease the use of the commit-message hook.

git-commit-hook install

Installs the commit-hook in the configured repositories.

You need to specify either -p or -a.

• -p to install in the given repository (eg. -p "project xyz")
• -a to install in all configured repositories

If there's already a commit-message-hook installed, you can overwrite by adding -f.

git-commit-hook uninstall

Uninstalls the commit-hook from the configured repositories.

You need to specify either -p or -a.

• -p to uninstall from the given repository (eg. -p "project xyz")
• -a to uninstall from all configured repositories

git-commit-hook diag

Gives an overview of the configuration and the installed commit hooks

git-commit-hook test

The test command is useful to test configuration and simulate a commit-situation.

You may input the following parameters:

• -p project name
• -b branch name
• m commit message

Sample:

git-commit-hook test -m "short commit message" -b master -p testrepo

in this case, validation will fail, since it's required to give a ticket/issue reference in the commit message.

testing configuration '/home/nils/.config/git-commit-hook/git-commit-hook.yaml':
project        : testrepo
branch         : master
commit message : short commit message

validation error for branch 'master'
at least expected one of the following to match
 - must have a ticket reference (eg. #267)

If you pass a valid commit message

git-commit-hook test -m "fix #121" -b master -p testrepo

shows not validation errors, but shows the finally rendered message.

testing configuration '/home/nils/.config/git-commit-hook/git-commit-hook.yaml':
project        : testrepo
branch         : master
commit message : fix #121

would generate the following commit message:
fix #121
