0.5.0 • Public • Published

JSOT-BH NPM version Build Status Dependency Status Coveralls Status

This is modification of JSOT template engine, which provides BH matchers and some other things.

Migration notice

This library is not maintained by BH developers and can't be used as as-is replace for bh package. Use with cautition!

Matchers

Matcher - function passed as second argument to BH.match.

It accepts context object with helper methods (which essential just an instance of JSOT-BH) and current processed object as second argument.

It can call applyBase method of context object, which applies all matchers to current processed object.

It can return new object as replacement of current object (useful for wrapping) - which can contain current object in content property or in an arrary.

JSOT-BH will restart apply procedure for returned object until it will be processed with all matchers, that corresponds to this block.

API

Context methods is similar to BH specification.

Usage

var JSOTBH = require('./index.js');
var jsotbh = new JSOTBH();
 
jsotbh.match('html', function (ctx) {
    ctx.tag('html');
});
 
jsotbh.match('p', function (ctx) {
    ctx.tag('p');
});
 
jsotbh.match('p_bold_yes', function (ctx) {
    ctx.cls('boldy');
});
 
console.log(
    jsotbh.apply({
        block: 'html',
        content: [
            { block: 'p', content: 'You' },
            { block: 'p', mods: { bold: 'yes' }, content: 'Rock!' }
        ]
    })
);
 
// should output: '<html class="html"><p class="p">You</p><p class="p p_bold_yes boldy">Rock!</p></html>'

Benchmark

This numbers can be used as "fastest possible" BH performance, but not necessary achivable (jsot-bh is lacking some functionality - see API status for details).

While single block/element rendering is much faster, than BH, real-life pages is rendered slower, than BH (by 7%).
