v6.5.1

Now bem-xjst trim and escape cls. Example:

// Template:
block('b1').elem('e1').content()(function() {
    return JSON.stringify(this.mods);
});

// BEMJSON:
[
    { block: 'b1', cls: '">' },
    { block: 'b2', cls: '   hello    ' }
]

Result before fix (v6.5.0):

<div class="b ">"></div>
<div class="   hello    "></div>

Result after fix (v6.5.1):

<div class="b &quot;>"></div>
<div class="hello"></div>

v6.5.0

bemhtml.compile() and bemtree.compile() should work with arrow functions and function with name and params.

var bemhtml = require('bem-xjst').bemhtml;

var myFunction = function() {
    block('page').tag()('body');
};

// myFunction can be in v6.5.0:
//   function name() { … }
//   function (a, b) { … }
//   function name(a, b) { … }
//   () => { … }
//   (a, b) => { … }
//   _ => { … }

var templates = bemhtml.compile(myFunction);

v6.4.3

bem-xjst should not render attrs if it’s not hash. Strings, arrays, and etc.
Example:

// BEMJSON:
{ block: 'b', attrs: [ 1, 2 ] }

Result before fix (v6.4.2):

<div class="b" 0="1" 1="2"></div>

Result after fix (v6.4.3):

<div class="b"></div>

v6.4.2

bem-xjst should not inherit mods from namesake parent block. Example:

// BEMJSON:
{
    block: 'b1',
    mods: { a: 1 },
    content: { block: 'b1' }
}

Result before fix (v6.4.1):

<div class="b1 b1_a_1"><div class="b1_a_1"></div></div>

Result after fix (v6.4.2):

<div class="b1 b1_a_1"><div class="b1"></div></div>

bem-xjst should not match on removed mods. Example:

// Template:
block('b1').mod('a', 'b').replace()(function() {
    return {
        block: 'b1',
        content: 'content'
    };
});

// BEMJSON:
{
    block: 'b1',
    mods: { a: 1 }
}

Result before fix (v6.4.1): endless loop :(

Result after fix (v6.4.2):

<div class="b1">content</div>

• [c2f697f71a] - We don’t need it anymore (Vasiliy Loginevskiy)
• [ed7624ac91] - Simple example (miripiruni)

v6.4.1

Bug fixed: in case of same block mods disappearing. Now bem-xjst keeps it. Example:

// Template:
block('b1').elem('e1').content()(function() {
    return JSON.stringify(this.mods);
});

// BEMJSON:
{
    block: 'b1',
    mods: { a: 1 },
    content: { block: 'b1', elem: 'e1' }
}

Result before fix (v6.4.0):

<div class="b1 b1_a_1"><div class="b1__e1">{}</div></div>

Result after fix (v6.4.1):

<div class="b1 b1_a_1"><div class="b1__e1">{"a":1}</div></div>

Now you can pass to bemxjst.compile named function.

v6.4.0

New option for content escaping: escapeContent.

In v6.4.0 escapeContent is set to false by default but will be inverted in one of the next major versions.

Example:

You can set escapeContent option to true to escape string values of content field with xmlEscape.

var bemxjst = require('bem-xjst');
var templates = bemxjst.bemhtml.compile(function() {
    // In this example we will add no templates.
    // Default behaviour is used for HTML rendering.
    }, {
        // Turn on content escaping
        escapeContent: true
    });

var bemjson = {
    block: 'danger',
    // Danger UGC content
    content: '&nbsp;<script src="alert()"></script>'
};

var html = templates.apply(bemjson);

Result:

<div class="danger">&amp;nbsp;&lt;script src="alert()"&gt;&lt;/script&gt;</div>

If you want avoid escaping in content use special value: { html: '…' }.

If you already use this.xmlEscape() on content values please don’t forget to remove it.

6.3.1

Improved error message about no block subpredicate.

Example:

$cat noblock.js
var bemxjst = require('bem-xjst');
var bemhtml = bemxjst.bemhtml;
var templates = bemhtml.compile(function() {
    tag()('span');
});


$ node noblock.js
/Users/miripiruni/Documents/www/bem-xjst-errors/lib/compiler.js:59
      throw new BEMXJSTError(e.message);
      ^
BEMXJSTError: block(…) subpredicate is not found.
    See template with subpredicates:

    And template body:

    at Object.<anonymous> (.../noblock.js:3:25)
    …

6.3.0

New option elemJsInstances for support JS instances for elems (bem-core v4+).

In v6.3.0 elemJsInstances is set to false by default but will be inverted in one of the next major versions.

var bemxjst = require('bem-xjst');
var templates = bemxjst.bemhtml.compile(function() {
    // In this example we will add no templates.
    // Default behaviour is used for HTML rendering.
    }, {
        // Turn on support for JS instances for elems
        elemJsInstances: true
    });

var bemjson = {
    block: 'b',
    elem: 'e',
    js: true
};

var html = templates.apply(bemjson);

Result with v6.2.x:

<div class="b__e" data-bem='{"b__e":{}}'></div>

Result with v6.3.0:

<div class="b__e i-bem" data-bem='{"b__e":{}}'></div>

Notice that i-bem was added.

v.6.2.0

2016-03-24, v6.2.0, @miripiruni

New xhtml option. Default value is true. But in next major version we invert it.

xhtml option allow you to ommit closing slash in void HTML elements (only have a start tag).

Example for v6.2.0:

 var bemxjst = require('bem-xjst');
 var templates = bemxjst.bemhtml.compile(function() {
     // In this example we didn’t add templates
     // bem-xjst will render by default
     }, {
         // Turn off XHTML
         xhtml: false
     });

 var bemjson = { tag: 'br' };
 var html = templates.apply(bemjson);

v6.2.0 result:

 <br>

v6.1.1 result:
