Custom title and lines highlighting

You can now specify a custom code block header title. For example, users can provide a filename for code blocks instead of writing it in the text or putting the whole code block inside a spoiler with filename title.

Moreover, you can even highlight certain lines!

Custom title and lines to be highlighted can be set via "Insert code" dialog:


You can also set the title and lines to highlight directly in text editor by adding title="..." and highlight="..." parameters in code bbcode.

Example: [code lang="php" title="My Custom Title"]<? .... ?>[/code] will produce this codeblock:


Hovering custom title will show the code language:


Example of highlighting: [code lang="php" highlight="2, 5-8"]a log of code...[/code]


Expand/Collapse buttons

Expand button smoothly increasing the height of code block until all the code is showing. It is visible only when code block height is LESS than the actual code size.

Collapse button smoothly decreasing the height of code block to it's default height which you can set in style properties. It is visible only when code block height is LARGER than default code block height.


Both expand and collapse buttons are visible when code block height is within min and max limits and invisible on code blocks that are smaller than default code block height.

The default height of code block can be set in style properties ("Code" section below "Messages"):


Copy button

Copy button simply copy the code right into your clipboard:


Line numbers

All code blocks have line numbers (up to 1000 lines). Line numbers can be turned off via style properties:



Every code block which code height is larger than the default height has a resizer bar. It allows users to vertically resize code block:


Common languages

I always thought there is something wrong about "Common languages". Why can't we set which languages are "common" to our specific forum? Weird...

With Code addon you can now set common languages right after "Allowed code languages" option in "Messages" option-group:




Default language

You can also set a default language code for "Insert code" dialog via "Default code language" option after common languages in "Messages" option-group:


Custom code block CSS class

There is an option to add a custom CSS class for code block. Just specify class="..." BB code attribute for that. Now you can style code blocks with this class. Here is an example:



  1. Download the addon
  2. Upload contents of upload folder to your forum root
  3. In admin control panel go to "Addons" section and install Code

WARNING: after unistalling all code blocks with custom titles/highlighting/class will not be rendered as code blocks!
  1. Uninstall the addon from ACP
  2. Go to forum root folder and remove js/CMTV/Code folder.
That's it!

Bad support since weeks... Some people gets some error or dysfunction but no help provided from @CMTV.
Very helpful to have the copy to clipboard feature and to have the expanding feature. It makes using the "code" bbcode preferable than to use the "list" bbcode for example. Thank you.
Excellent addon :)
I really appreciate free addons like this, it helps a lot.
Keep up the good work!!!
Works perfectly! Great for communities that post a lot of coding examples. Support is great, helps you with all your issues.
Fantastic add-on! Now my forum's codes are very simple to manage and copy/paste for my users!

Congratulations to developer ;)
I was able to add in a lua and VB language packs and had it all working almost instantly! (... instantly after I striped out all of the "visual-basic" references in the .min.js and rename them to "vb", and then use vb everywhere.) Great add on, I really appreciate it!

Follow instructions here for additional languages:
This mod is great, it does line numbers and copy button and dark/light theme and expand all in one mod. You had to use 3 mods before to get 75% of this functionality.
Love it, I always have to share code and the default viewer misses exactly what this addon does. Must have if you share code in your community.
