# Syntaxhighlighter_XH



Syntaxhighligher_XH facilitates improved presentation of code snippets in

the content, for visitors having JavaScript enabled. The actual work is done by

[Alex Gorbatchev’s Syntaxhighlighter](https://github.com/syntaxhighlighter/syntaxhighlighter);

Syntaxhighlighter_XH merely is meant to simplify

the integration in CMSimple_XH. For some content editors, plugins are

available which make editing even more convenient.

## Requirements



Syntaxhighligher_XH is a plugin for CMSimple_XH.

It requires CMSimple_XH ≥ 1.7.0, and PHP ≥ 7.1.0 with the *json* extension.



## Download



The [lastest release](https://github.com/cmb69/syntaxhighlighter_xh/releases/latest)

is available for download on Github.



## Installation



The installation is done as with many other CMSimple_XH plugins. See the

[CMSimple_XH Wiki](https://wiki.cmsimple-xh.org/?for-users/working-with-the-cms/plugins)

for further details.



1.  **Backup the data on your server.**

1.  Unzip the distribution on your computer.

1.  Upload the whole directory `syntaxhighlighter/` to your server into

    into the `plugins/` directory of CMSimple_XH.

1.  Set write permissions to the subdirectories `config/`, `css/` and

    `languages/`.

1.  Navigate to `Plugins` → `Syntaxhighlighter` in the back-end

    to check if all requirements are fulfilled.



For an improved user experience in the editors, you *may* need to do some

additional setup. This is not necessary for recent versions of TinyMCE4

and TinyMCE5.



### TinyMCE4



1. Add the following line to `external_plugins`:



        "syntaxhl": "%CMSIMPLE_ROOT%plugins/syntaxhighlighter/editors/tinymce4/syntaxhl/plugin.min.js"



1. Add the `syntaxhl` button to `toolbarN` wherever you prefer.



### TinyMCE5



1. Add the following line to `external_plugins`:



        "syntaxhl": "%CMSIMPLE_ROOT%plugins/syntaxhighlighter/editors/tinymce5/syntaxhl/plugin.min.js"



1. Add the `syntaxhl` button to `toolbar` wherever you prefer.



### CKEditor



1. Copy `plugins/syntaxhighlighter/editors/ckeditor/syntaxhighlight/` to

   `plugins/ckeditor/plugins_external/`.



## Settings



The configuration of the plugin is done as with many other CMSimple_XH plugins in

the back-end of the Website. Select `Plugins` → `Syntaxhighlighter`.



You can change the default settings of Syntaxhighlighter_XH under

`Config`. Hints for the options will be displayed when hovering over

the help icons with your mouse.



Localization is done under `Language`. You can translate the character

strings to your own language if there is no appropriate language file

available, or customize them according to your needs.



The look of Syntaxhighlighter_XH can be customized under `Stylesheet`.



## Usage



Add code snippets you like to be presented with syntax highlighting to your pages by

enclosing it in a `
` element with a class as described in

[the manual of Syntaxhighlighter](https://github.com/syntaxhighlighter/syntaxhighlighter/wiki/Configuration)



For TinyMCE 4 and 5 inserting and editing the code snippets can be done by pressing the

`Insert/Edit code sample` button, where you can edit the code snippets and

choose the desired language. Other settings have to be done manually in the

HTML source code view.



For CKEditor inserting and editing the code snippets can be done by pressing the

`Add or update a code snippet` button, where you can edit the code snippets and

the settings.



## Limitations



The syntax highlighting, line numbering etc. requires a contemporary browser

(e.g. IE is not supported) with JavaScript enabled. In other environments the code

snippets are presented unenhanced.



## Troubleshooting



Report bugs and ask for support either on

[Github](https://github.com/cmb69/syntaxhighlighter_xh/issues)

or in the [CMSimple_XH Forum](https://cmsimpleforum.com/).
