An extendable php commit hook

1. Download binary https://github.com/bigtallbill/hooker/releases/tag/0.1.0
2. Copy the binary release to a directory that is loaded by your PATH
3. Make the file executable chmod a+x hooker
4. Check installation which hooker

1. open a terminal and cd to the target repository
2. run hooker install

This will install a hooker.json config file and also update the commit hook files for this repo to execute hooker

Now when you try to commit something for example. hooker will execute.

The hooker.json config file contains settings for each type of hook.

{
    "preCommit": {},
    "commitMsg": {
        "firstWordImperative": true,
        "maxSummaryLength": 50,
        "maxContentLength": 72,
        "summaryIgnoreUrls": true,
        "contentIgnoreUrls": true,
        "lineAfterSummaryMustBeBlank": true,
        "scripts": {
            "after": [
                {
                    "cmd": "runtests.sh",
                    "passGitArgs": false,
                    ""
                }
            ]
        }
    }
}

Every hook type can have the element scripts. This allows you to execute arbitrary code that is not a native hooker check.

"scripts": {
    "after": [
        {
            "cmd": "runtests.sh"
        }
    ]
}

The "after" key defines when to run the script (currently after is the only one). After means run after hooker's own internal code for that hook.

Then we have an array of scripts to run.

Here is a sample script object:

{
    "cmd": "runtests.sh",
    "passGitArgs": false,
    "relativeToRepo": false
}

"cmd" is the command to execute

"passGitArgs" When set to true will append the git arguments onto the scripts existing arguments

"relativeToRepo" Execute this script relative to the repo. Currently this is pretty dumb, it will just prepend the repository path to the cmd.
