gruntjs - Launch grunt task passing params on git commit -

i starting grunt, have defined task , work charm:

module.exports = function(grunt) {  grunt.initconfig({      jshint: {         force: false,         options: {             evil: true,             regexdash: true,             browser: true,             wsh: true,             trailing: true,             multistr: true,             sub: true,             loopfunc: true,             expr: true,             jquery: true,             newcap: true,             plusplus: false,             curly: true,             eqeqeq: true,             globals: {                 jquery: true             }         },         src: ['workspace/**/*.js']     }  });   grunt.loadnpmtasks('grunt-contrib-jshint'); grunt.registertask('default', ['jshint:src']);   }; 

now, launch task passing src param (with git commited files).

i have tried pre-commit script in .git folder, does´t work:

var exec = require('child_process').exec;  exec('grunt jshint', {        cwd: 'c:\\workspace',        src: 'subfolder\\**\\*.js'      }, function (err, stdout, stderr) {    console.log(stdout);    var exitcode = 0;   if (err) {     console.log(stderr);     exitcode = -1;   }    process.exit(exitcode); }); 

how can pass params in execution time grunt task?

thanks lot, best regards.

if want pass command line parameters grunt, have to:

1. on command line, use syntax --paramname=value
2. in gruntfile, use grunt.option('paramname')

so in case call

exec('grunt jshint --src=subfolder\\**\\*.js', {cwd: 'c:\\workspace'}, function (err, stdout, stderr) {...}); 

and gruntfile be:

jshint: {     (...)     src: [grunt.option('src')] }
