# JSOT-BH [![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Dependency Status][depstat-image]][depstat-url] [![Coveralls Status][coveralls-image]][coveralls-url]
This is modification of [JSOT](https://github.com/floatdrop/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](https://github.com/enb-make/bh#%D0%9A%D0%BB%D0%B0%D1%81%D1%81-ctx) specification.
## Usage
```js
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: 'You
Rock!
'
```
## 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 with same speed.
