  • language (string, mandatory): any supported rosaeNLG language (all templates must have the same language)

  • dest (string, mandatory): the destination js filename

  • holderName (string, mandatory): the name of the package that will hold all the functions

  • tinyify (boolean, optional): put true if you want to tinyify the output

renderTemplateInFile renders a RosaeNLG template into a file:

  • template (string, mandatory): the filename of the template to render

  • dest (string, mandatory): the filename that will contain the output

  • options (mandatory): the parameters that will be given to renderFile; typically put language and most often some data.

    • expected: string[]; strings that should be in the rendered template

var gulpRosaeNLG = require('gulp-rosaenlg');
const fs = require('fs');

const tmpFile = 'tmp.js';

let os = gulpRosaeNLG.compileTemplates([{source: 'test/test.pug', name:'test'}], 'en_US', tmpFile, 'templates_holder');

os.on('finish', function() {
  console.log('DONE');
  const compiledString = fs.readFileSync(tmpFile, 'utf-8');
  console.log(`done: ${compiledString.length}`);
  // fs.unlinkSync(tmpFile);
});
