pugneum-filterer

Code for processing filters in pugneum templates

Installation

npm install pugneum-filterer

Usage

var filter = require('pugneum-filterer');

filter(ast, filters)

Renders all Filter nodes in a pugneum abstract syntax tree.

filters is an object mapping names to filter descriptor objects:

{
  custom: {
    filter: function(text, options) {
      return 'filtered' + text;
    },

    binary: false
  }
}

custom is the name of the filter as written in the pugneum template. Every key maps a name to an object describing the filter of that name.

The filter descriptor is an object whose filter property is a function that processes the text. This is the only strictly required property. If binary is specified as true, the filter receives a raw input buffer containing binary data instead of already decoded text. Support for more metadata will probably be added later.

When a filter is used in a pugneum template but is not present in the custom filters map, the filterer will require a package named pugneum-filter-${name} which is expected to return the filter descriptor object. If not found, the result is an error.
