syntaxhighlighter-ng

based on the original FlatPress plugin from 2005, updated in 2023 to prism.js

codeblock with language syntax highlightning

When you just create an [code][/code] block, then there will be no syntax highlightning.

To enable it, you have to specify the language you want to get highlighted, for example:

[code=bash]
if [ "$1" == "bash" ] 
then
  echo "Yeah :)"
else 
  echo "something else"
fi
[/code]

See the https://prismjs.com/#supported-languages for all supported languages by the contained prism.full.js

The included prism.small.js just has the most popular I know:

Markup + HTML + XML + SVG + MathML + SSML + Atom + RSS + CSS + C-Linke + JavaScript + Apache + Bash + Batch + BBCode + C + C# + C++ + CSV + Diff + Go + HTTP + ini + Java + JSON + Makefile + Markdown + nginx + Perl + PHP PowerShell + Python + Ruby + Shell session + SQL + VB.Net + Wiki markup + YML

To change the theme, choose your favorite from https://prismjs.com and place it into fp-plugins/syntaxhighlighter/res/. Then look after the block <!-- start of prism.js header --> in fp-plugins/syntaxhighlighter/plugin.syntaxhighlighter.php and change the following line:

<link rel="stylesheet" type="text/css" href="{$pdir}res/prism.okaidia.css" />

to

<link rel="stylesheet" type="text/css" href="{$pdir}res/prism.YOURTHEMENAME.css" />
