npm install handlebars-exActually this is just a PEGjs grammar that auto-generates a parser to recognize Handlebars.js-like
javascript
npm install handlebars-ex
`$3
javascriptvar handlebarsX = require('handlebars-ex');
var ast = handlebarsX.parse('
{{#if cond}}
{{/if}}');`Tests
All test are written in Jasmine. To run them:
javascript
npm test
`Limitation
It is important to notice that NOT ALL handlebars templates are valid handlebars-ex templates.The grammar used here is not the same used by Handlebars. With Handlebars you are able to generate ANY template; C#, JavaScript, HTML or simple Plain Text.
This is not the case of handlebars-ex. Here we only accept/recognize a subset of HTML-Handlebars templates.
This means based on the current grammar, there are templates that WONT be recognized.
Grammar limitations:
- Variable tag name are not supported. Sample:
HTML
<{{tagName}}> some content here
` - XML Structure is mandatory for non void tags. This means that you CANNOT conditionally (inside a IF condition) close a tag. Besides, as a consequence of the previous all open tag must have a closing tag. None child tag is allowed to close or add context outside the closing parent tag. Samples:
HTML
{{#if condition}} {{else}} ...
