Add, Commit and Push at Once using GULP-GIT

问题

I'm trying to create a task that does add . , commit, and push in a single command line like : gulp gitsend -m "My changes"

var gulp = require('gulp');
var argv = require('yargs').argv;
var git = require('gulp-git');

gulp.task('gitsend', function() {
if (argv.m) {
    console.log('adding, commiting and pushing to git...');
    return gulp.src('.')
    .pipe(git.add())
    .pipe(git.commit(argv.m)
    .pipe(git.push('origin', 'master', function (err) {
        if (err) throw err;
    })));
}
});

But this is not working: it throws an exception:

/Users/me/myproj/front/node_modules/gulp-git/node_modules/through2/node_modules/readable-stream/lib/_stream_readable.js:623
    var written = dest.write(chunk);
                       ^

Any idea what's wrong and how can I archive my need ? Thank you.

You can split the individual tasks out (add, commit, push) and then run them using run-sequence to ensure that add and commit are done first before pushing.

var gulp = require('gulp');
var argv = require('yargs').argv;
var git = require('gulp-git');
var runSequence = require('run-sequence');

gulp.task('init', function() {
  console.log(argv.m);
});

gulp.task('add', function() {
  console.log('adding...');
  return gulp.src('.')
    .pipe(git.add());
});

gulp.task('commit', function() {
  console.log('commiting');
  if (argv.m) {
    return gulp.src('.')
      .pipe(git.commit(argv.m));
  }
});

gulp.task('push', function(){
  console.log('pushing...');
  git.push('origin', 'master', function (err) {
    if (err) throw err;
  });
});

gulp.task('gitsend', function() {
  runSequence('add', 'commit', 'push');
});
