PutOnAHelmet (Put on a helmet)

By: @staxmanade

Set of build script/tasks that you can use to easily run to install git pre-commit hooks for such things as running tests before your code is committed.

• Shell - Make
• Ruby - Rake
• Gulpjs
• PowerShell - Invoke-Build
• PowerShell - PSake

<a name="shell"/> ### Shell Make ```shell # Installs pre commit hook installCommitHook: @[ ! -f .git/hooks/pre-commit ] || { echo "pre-commit hook file already exists."; exit 1; } @echo "#!/bin/sh\nmake test" > .git/hooks/pre-commit; @chmod a+x .git/hooks/pre-commit @echo "pre-commit hook installed!" ``` <a name="rubyrake"/> ### Ruby [Rake](https://github.com/ruby/rake) ```ruby

desc 'Places a git pre-commit hook that runs the "rake test" command before each commit. You can skip the pre-commit by typing "git commit -n ...' task :putOnAHelmet do fileContents = <<-eos !bin/sh rake test eos File.open('.git/hooks/pre-commit', 'w') {|file| file.write(fileContents) } sh "chmod +x .git/hooks/pre-commit"

puts 'pre-commit hook installed'

end

<a name="gulpjs"/>
### Gulp [Gulpjs](http://gulpjs.com/)
```JavaScript
  gulp.task('putOnAHelmet', function () {
    var testFileString = '!bin/sh\ngulp test';
    var fs = require('fs');
    var preCommitHookFile = '.git/hooks/pre-commit';
    if(fs.existsSync(preCommitHookFile)) {
      throw 'pre-commit hook file already exists. Don\'t want to override it (case you have a custom special one in there..).';
    } else {
      fs.writeFileSync(preCommitHookFile, testFileString);
      require('child_process').exec('chmod +x ' + preCommitHookFile);
    }
  });

<a name="powershellInvokeBuild"/> ### PowerShell [Invoke-Build](https://github.com/nightroman/Invoke-Build)

# Synopsis: Places a git pre-commit hook that runs the 'test' psake command before each commit. You can skip the pre-commit by typing "git commit -n ..."
task putOnAHelmet {
    $cmd = '#!/bin/sh
#***********
exec powershell -NoProfile -command "Invoke-Build.ps1 Test"
#***********
'
    $hookPath = ".git/hooks/pre-commit"
    if( test-path $hookPath ){
        throw "The git pre-commit hook file already exists. Verify that this command is in there. $cmd"
    } else {
        $hookFile = cat "$hookPath.sample" | Out-String
        $hookFile = $hookFile.Replace('exec git diff-index --check --cached $against --', '#exec git diff-index --check --cached $against --')
        $hookFile = $hookFile + $cmd
        sc $hookPath $hookFile
    }
    "Pre-commit hook installed!"
}
