git_hooks

https://img.shields.io/github/license/xuzhongpeng/git_hooks Pub Star

git_hooks can prevent bad git commit,git push and more easy in dart and flutter! It is similar to husky.

Install

dev_dependencies:
  git_hooks: ^0.1.0

then

pub get

or

flutter pub get

create files in .git/hooks

Here has two ways

  1. Using git_hooks command

activate git_hooks in shell

pub global activate git_hooks

Now,we can let the git hooks bring into effect

git_hooks create bin/git_hooks.dart
  1. Using dart code:

create main.dart file in /bin/

void main() async{
  GitHooks.init(targetPath: "bin/git_hooks.dart");
}

then dart bin/main.dart in shell.

It will create some hooks files in .git/hooks. You can check whether the installation is correct by judging whether the file(".git/hooks/commit-msg" and other fils) exists.

It will create a file git_hooks.dart in your project root directory.

Delete files in .git/hooks

  1. using git_hooks shell command
git_hooks uninstall
  1. using dart codes
void main() async{
  GitHooks.unInstall();
}

Notion

Target File: The file that the git hooks points to. It is /git_hooks.dart as default.

Git hook command file: The Git hooks file. Such as /.git/hooks/commit-msg.

Using

You can change git_hooks.dart

import "package:git_hooks/git_hooks.dart";
import "dart:io";

void main(List arguments) {
  Map<Git, UserBackFun> params = {
    Git.commitMsg: commitMsg,
    Git.preCommit: preCommit
  };
  GitHooks.call(arguments, params);
}

Future<bool> commitMsg() async {
  String rootDir = Directory.current.path;
  String commitMsg = Utils.getCommitEditMsg();
  if (commitMsg.startsWith('fix:')) {
    return true; // you can return true let commit go
  } else
    return false;
}

Future<bool> preCommit() async {
  try {
    ProcessResult result = await Process.run('dartanalyzer', ['bin']);
    print(result.stdout);
    if (result.exitCode != 0) return false;
  } catch (e) {
    return false;
  }
  return true;
}

If you want interrupt your commit or push,you can return false.Then you can return true if only nothing to do.

add file to git

git add .
git commit -m 'some messages'

If it output following.Congratulations on your successful use of it.

start pre-commit hook...               /
-this is pre-commit

1.1s
start commit-msg hook...               /
\commit message is 'some messages'
this is commitMsg

Define our own hook functions

You can use enum Git to Define more hooks functions.

There is all hooks provide

enum Git {
  applypatchMsg,
  preApplypatch,
  postApplypatch,
  preCommit,
  prepareCommitMsg,
  commitMsg,
  postCommit,
  preRebase,
  postCheckout,
  postMerge,
  prePush,
  preReceive,
  update,
  postReceive,
  postUpdate,
  pushToCheckout,
  preAutoGc,
  postRewrite,
  sendemailValidate
}

Debugging hooks code with VSCode

If you debugging pre-commit hooks.

You can execute dart {{targetFile}} pre-commit.

or add Configuration in VSCode

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "debugger git hooks",
      "program": "git_hooks.dart",//your targetFile
      "request": "launch",
      "type": "dart",
      "args": ["pre-commit"] // hooks argument
    }
  ]
}
