Syntax highlighting

Syntax highlighting and auto completion is available for Atom editor. Syntax highlighting is triggered on .bow-files.

Usage with gulp

Gulp compatible compiling comes out of the box with Bowtie, example:

var gulp = require('gulp');
var bowtie = require('bowtie-js').gulp;

gulp.task('bowtie', function() {
  return gulp.src('*.bow')
    .pipe(bowtie({
      // Pretty output
      "pretty": true,
      // Object to pass to template engine
      "locals": {
        "title": "Example application"
      }
    }))
    .pipe(gulp.dest('./dist'));
});
