An example gulpfile.js to use Tale Jade with WordPress (or similar template engines)

gulpfile.js

var gulp = require('gulp'),
    exec = require('gulp-exec');

var templateFiles = [
  'wp-content/themes/my-theme/index.jade',
  'wp-content/themes/my-theme/page.jade',
  'wp-content/themes/my-theme/page-single.jade',
  'wp-content/themes/my-theme/archive.jade',
  //All other template files
  //Make sure they reside at the exact same positions where the wordpress files would be
],
    compilerCommand = 'tale-jade';

gulp.task('build', function(done) {

    var doneCount = 0;
    templateFiles.forEach(function (path) {
      
        //Put together the command to run (e.g `tale-jade compile whatever.jade whatever.php`)
        var command = compilerCommand + ' compile ' + path + ' ' + path.slice(0, -4) + '.php';
        
        //Run the command asynchronously
        exec(command, function (err, stdout, stderr) {
            
            //Log stuff
            console.log(stdout);
            console.log(stderr);
            
            //Count to tell gulp when we finished (via done())
            doneCount++;
            if (doneCount === templateFiles.length)
                done();
        });
    });
});

gulp.task('watch', function() {

    gulp.watch(['wp-content/themes/**/*.jade'], ['build']);
});

gulp.task('default', ['watch']);
