git-config-manager

git-config-manager is a tool for setting git configurations by schemes described in json file. It is useful in situations when you can specify different sets of configurations for different repositories (like work, personal etc) and want to avoid typing configurations by hand for every single repository.

For example, consider following content in $XDG_CONFIG_HOME/git/git-config-manager.json (which is loaded by default if you don’t override it using --config-file option).

{
  "personal": {
    "user": {
      "name": "The Donkey",
      "email": "mybossdontknowme@protonmail.ch",
      "signingkey": "ABCDEFGH"
    }
  },
  "my_project": {
    "pull": {
      "rebase": true
    }
  },
  "work": {
    "user": {
      "name": "Mr. Doe",
      "email": "slave012345@corp.me",
      "signingkey": "ABCDEFGH"
    },
    "pull": {
      "rebase": null
    }
  }
}

You can navigate to any repository and call git-config-manager set personal to set all configurations under personal scheme.

Note that supported value types are strings, numbers and booleans. If you set the value to null, it will be unset (and in case corresponding section is empty it will be also removed).

Install

The easiest way to install git-config-manager is to use stack.

$ git clone https://github.com/d12frosted/git-config-manager.git
$ cd git-config-manager
$ stack install

Magit interface

Git configuration manager comes with magit interface. It just adds new section to status buffer. All available actions are available under C key. In order to set configuration scheme selected desired scheme and press C s. In order to unset it - C u.

Install

While package is not available on MELPA, one can install it using quelpa. After magit-gcm is available on your load-path, just add following snippet to your init.el.

(require 'magit-gcm)
(add-hook 'magit-mode-hook 'turn-on-magit-gcm)

Configure

There are several configuration variables available to users.

• magit-gcm-exectuable - by default it searches for executable in PATH. If for some reason it can’t be found or you just wish to manually specify it - set this variable.
• magit-gcm-config-file - by default it’s nil, which means that magit-gcm will not pass configuration file path to git-config-manager, so the default configuration file will be used. But in some cases it might be useful to manually set this variable.
• magit-gcm-mode-lighter - mode line lighter for magit-gcm-mode.

For convenience, magit-gcm exposes several utility functions.

• magit-gcm-exec - for executing git-config-manager commands.
• magit-gcm-get-active-schemes - returns list of currently activated configuration schemes.
• magit-gcm-get-available-schemes - returns list of all available configuration schemes.
