I have installed and enabled a code highlighter that will highlight code syntax in a Code Block.

Indicate the language in the BBCode for example
code=bash
code=python

Also code=none turns code highlighting OFF

Please report if any problems or conflicts occur.

I have installed and enabled a code highlighter that will highlight code syntax in a Code Block.

How do we use it and can we specify the programming language?

I'm guessing we use the standard bbcode way:

var foo = `some ${string}`;

const bar = (cfg = { ...one, ...two }) => cfg.toString();

And here is the Markdown way (seems unsupported, but hey ho, no biggie)

var foo = `some ${string}`;

....so the above test shows you need to write your code in bbcode code blocks, not markdown-style backticks, if you want it to get syntax highlighting..

If I add in your bbcode style code block code=js it doesn't produce an error. However, this test isn't enough to tell me if the syntax highlighting takes language into account. If language is taken into account then I'd like to know which languages are supported.

@s243a You might need to enable Markdown by unchecking the box down on the bottom of the post editor. I have modified the code to always load the post editor with Markdown disabled by default.

Markdown enabled and using 3 tick marks

var foo = `some ${string}`;

@s243a

The system is using highlight.js which recognizes 189 programming and scripting languages, automatically. Also highlights configuration files like those from the Apache Web Server or .htaccess

Here is the link for a demo.

Thankyou for the info

That said, it would still be nice to be able to specify the programming/scripting language...but perhaps you can with this system?

I am looking into the possiblity although it seems not possible to specify. The orginal BBCode code block used to take code=php but that was it. I only see so far that it automatically detects the language being used.

See the demo for more

Seems to be possible with BBCodes

code=js

var foo = `some ${string}`;

code=awk (likely not valid awk)

var foo = `some ${string}`;

code=C++

cout << "Enter an integer: ";

code=php

<?php echo "The Best PHP Examples"; ?>

This is not "highlighting". Quite the opposite. Can you read this?

@MochiMoppel

I have not yet looked at the ne-blackgreen style version of the code highlighter. I only have so much time in the day for a full time job I don't get paid for. I can always remove it.

I will examine the CSS for the style to see what can be done

positive re-enforcement is a thing.

On my computer it looks like this which shows a different highlighting for each language.

I just gave you a "thanks". I like the code highlighting. Unfortuantly given MochiMoppel it still has some bugs but keep up the good work

@MochiMoppel

I think I might have fixed it...or we will be going off the rails any minute now.....either way, please test the code block out and report.

Your display looks OK to me, but mine is different. Using default Palemoon settings and default forum theme:

Slightly better when I use the dark ne-blackgreen theme because it uses a bigger font size, but still not comfortabe to read. I use the dark theme not because is looks fancy but because my eyesight is bad and text with a glaring white background is hard to read for me. The syntax highlighting deprives me of this choice. It enforces colored text on white background. Comments are displayed in light grey on white. This is the point when I have to throw in the towel.

@rockedge yes, seems to work now. What - not surprisingly - does not work is automatic language detection. Assuming that the vast majority of code snippets are written in bash/ash/sh it becomes mandatory to either add a shebang or indicate the language in BBcode like [code=bash]. I further assume that users will not do this because they never were required to do this. Simple snippets are posted without a shebang and enclose with what the Code button spits out. Take following example. The second without shebang shows highlighting without any meaningful context. Defeats the purpose of syntax highlighting.

#!/bin/sh
if [ -e /bin/cp  ];then
	echo "/bin/cp exists"
	grep . << XYZ 2>/dev/null
	/bin/cp exists
XYZ
else
	printf "%s" '/bin/cp missing'
fi

if [ -e /bin/cp  ];then
	echo "/bin/cp exists"
	grep . << XYZ 2>/dev/null
	/bin/cp exists
XYZ
else
	printf "%s" '/bin/cp missing' 
fi

code highlighting has been disabled for further testing.
