Changelog
=========

# 2.x

## 2.8.x

### 2.8.0

-  Added support for automatically discovering taglibs from installed packages that are scoped. ([PR #183](https://github.com/marko-js/marko/pull/183) by [@tropperstyle](https://github.com/tropperstyle)) 

## 2.7.x

### 2.7.31

- Fixes #167 - Nested tags only work one level deep

### 2.7.30

- docs: don't exclude docs in .npmignore

### 2.7.29

- Fixes #161 - Nested tags with no body content are not handled correctly

### 2.7.28

- Fixes #140 - Also de-dupe cached taglibs in finder

### 2.7.27

- Make loading template from String template source easier:

```javascript
var template = marko.load(
    templatePath,
    'Hello $!{data.name}!');
```

_NOTE: Loading directly from source only works on the server_

See [Pull Request #153](https://github.com/marko-js/marko/pull/153)

### 2.7.26

- Use shorter relative paths in error messages

### 2.7.25

- Fixes #150 - Provide option to prevent writing compiled templates to disk. Example usage:

```javascript
require('marko/compiler').defaultOptions.writeToDisk = false;
```

NOTE: If you disable writing compiled templates to disk then it will be a little harder to debug errors in templates on the server since the stack trace will refer to a file that has not been written to disk.

For a more complete list of compiler options please see: http://markojs.com/docs/marko/javascript-api/#defaultoptions

```xml
<compiler-options comments="preserve"/>
Hello
<!--This comment should be preserved-->
World
```

Output:

```xml
Hello
<!--This comment should be preserved-->
World
```

## 2.6.x

### 2.6.0

- Performance improvements
    - `'use strict';`
    - Optimized render code paths
- Code cleanup
- Compatibility fixes for Node.js 0.12
    - Bad: `fs.readFile(path, 'utf8')`
    - Good: `fs.readFile(path, {encoding: 'utf8'})`

## 2.5.x

### 2.5.0

- Fixes #78 - Custom Node.js require extension for Marko template files. Example usage:

```javascript
// Install the Node.js require extension in your application's main script (server-side only)
require('marko/node-require').install();

// Now you can require `*.marko` files just like any other JavaScript module
var template = require('./hello.marko');
var html = template.renderSync({ name: 'Frank' });
```

- Compiled templates now export a loaded Template instance. In the previous version of marko, compiled templates exported a function that could be used to create a loaded Template instance.

## 2.4.x

### 2.4.3

- Fixes edge case: More precise regular expression for decoding HTML entities

### 2.4.2

- Internal: Fixes #75 Always assign the tag property to custom tag nodes

### 2.4.1

- Improvement to allow taglibs to be imported from other taglibs ([commit](https://github.com/raptorjs/marko/commit/73e9a3420a1bac3e2c201d4dcadf21c0701b5222))

### 2.4.0

- Added support for short-hand tags and attributes

Old `marko-taglib.json`:

```json
{
    "tags": {
        "my-hello": {
            "renderer": "./hello-renderer",
            "attributes": {
                "name": "string"
            }
        }
    }
}
```

Short-hand `marko-taglib.json`:

```json
{
    "<my-hello>": {
        "renderer": "./hello-renderer",
        "@name": "string"
    }
}
```

- Fixes #61 Simplify parent/child relationships

Marko now supports custom tags in the following format: `<parent_tag.nested_tag>`

Example usage:

```html
<ui-tabs orientation="horizontal">
    <ui-tabs.tab title="Home">
        Content for Home
    </ui-tabs.tab>
    <ui-tabs.tab title="Profile">
        Content for Profile
    </ui-tabs.tab>
    <ui-tabs.tab title="Messages">
        Content for Messages
    </ui-tabs.tab>
</ui-tabs>
```

___ui-tabs/marko-tag.json___

```json
{
    "@orientation": "string",
    "@tabs <tab>[]": {
        "@title": "string"
    }
}
```

___ui-tabs/renderer.js___

```javascript
var template = require('marko').load(require.resolve('./template.marko'));

exports.renderer = function(input, out) {
    var tabs = input.tabs;

    // Tabs will be in the following form:
    // [
    //     {
    //         title: 'Home',
    //         renderBody: function(out) { ... }
    //     },
    //     {
    //         title: 'Profile',
    //         renderBody: function(out) { ... }
    //     },
    //     {
    //         title: 'Messages',
    //         renderBody: function(out) { ... }
    //     }
    // ]
    console.log(tabs.length); // Output: 3

    template.render({
        tabs: tabs
    }, out);

};
```

___ui-tabs/template.marko___

```html
<div class="tabs">
    <ul class="nav nav-tabs">
        <li class="tab" for="tab in data.tabs">
            <a href="#${tab.title}">
                ${tab.title}
            </a>
        </li>
    </ul>
    <div class="tab-content">
        <div class="tab-pane" for="tab in data.tabs">
            <invoke function="tab.renderBody(out)"/>
        </div>
    </div>
</div>
```

## 2.2.x

### 2.2.2

### 2.0.6

- `renderBody` function is only added if tag has children

### 2.0.5

- Fixed #36 - Don't use `invokeBody()` in the cache taglib

### 2.0.4

- :exclamation: Fixed #36 - Deprecated - When using `<include>` with body content, nested body content is now passed in as `String` property named `body`. Old behavior: nested content would be passed in as a `Function` property named `invokeBody` that would return the `String` value of the nested content. `invokeBody()` has been deprecated.

### 2.0.3

- Fixed #36 - Don't use `invokeBody()` in test code and the HTML comments tag

### 2.0.2

```html
<compiler-options whitespace="preserve" />
A
B
C
```

### 2.0.0


- Dynamic attributes for scanned tags without a tag will have dashes removed by default.
    - :exclamation: When using `tags-dir` to discover tags that do not have a `marko-tag.json`, the previous behavior was to allow all attributes and to use the actual attribute name as the input property name. For example, when using `<hello first-name="John">`, first name would need to be read in as `input['first-name']`. This was changed such that the first name property should now be read in as `input.firstName` (dashes removed and converted to camel case)
- Changes to allow UI component to be put into a single JS file:
    - Updated taglib directory scanner to use `index.js` if found. New search order:
        1. `renderer.js` (use `renderer.js` if it exists)
        2. `index.js` (use `index.js` if it exists and assume it exports a `renderer` or `render` property)
        3. `template.marko` (use the template as the renderer if no `renderer.js` or `index.js`)
    - :exclamation: Changes to the taglib directory scanner could break existing code. Specifically, if a UI component directory had an `index.js` file and a `template.marko` file then in in `marko@<2` the `template.marko` file would have been selected as the renderer. In `marko@2.x`, the `index.js` will be selected as the tag renderer.
- :exclamation: Removed support for mapping a tag renderer to a module with a `process` method
- Removed sub-module `marko/renderer` that exports [raptor-renderer](https://github.com/raptorjs/raptor-renderer)
