Add Builder

We are using nunjucks builder it is very easy to use.

It has the following Staps:

1. We have to add "gulp-nunjucks-render" : "^2.0.0" in package.json as dependencies.

2. gulpfile.js:

   We have to declare below global variables:

   var nunjucksRender = require('gulp-nunjucks-render'); var units1 = process.argv[2]; var units2 = process.argv[3]; var units3 = process.argv[4];

   var inputTemplates = resourcesAssets + 'pages/*.html' ;

   var siteOutput = './' ;

   We have to declare function:

   gulp.task('nunjucks', function() { var layout; var bc; if (units1&&units2&&units3&&units1=="nunjucks") { layout=units2.substring(2); bc=units3.substring(2); } return gulp.src(inputTemplates) .pipe(nunjucksRender({ path:['src/templates/'], data:{layout:layout, bc:bc} })) .pipe(gulp.dest(siteOutput)) });

   And call the function :

   elixir(function(mix) { //nunjucks mix.task('nunjucks'); });
