FWIW, the old [highlight] tags apparently are still active:

bash code:
  1. for((i=1; i<=n; i++)); do
  2.   printf "%s\n" "Hello World"
  3. done

c code:
  1. #include <stdio.h>
  2.  
  3. main()
  4. {
  5.     printf("Hello World!\n");
  6. }

java code:
  1. class HelloWorld {
  2.   static public void main( String args&#91;&#93; ) {
  3.     System.out.println( "Hello World!" );
  4.   }
  5. }

javascript code:
  1. <script>
  2.   alert( 'Hello, world!' );
  3. </script>

There is no "awk" however
awk code:
  1. BEGIN {
  2.   print "Hello World!"
  3. }

Issues with Highlight bbcode tags

I think the issue with the scrollbars and code tags boils down to the fact that this site uses very old HTML <table> attributes in the templates.

If I manually convert the HTML <table> attributes to <div> tags, I am pretty sure all these kind of annoying problems like scrollbars not working in code tags will go away.

Horizontal scrolling works fine on the mobile site, because I got rid of all the HTML <table> attributes when I updated it and replaced all with <div> tags.

<table> attributes are long dead. vBulletin 3.x is all <table> based, so there lies the problem, I am pretty sure.

It's a lot of work, but it might just be the best way forward.

Since the JS is a filter which creates new text, it's a one-way function.

This means to switch back-and-forth requires us to keep both code tags (original and JS filtered) and write some extra Javascript to switch back and forth.

It's doable, but not sure it is worth the coding extra effort since I am guessing most like the flexibility of the original code tags more than the syntax highlighting javascript.

As mentioned, editing is much easier when WYSIWYG.

That highlighter code uses GESHI and GESHI has an AWK filter for example.

There may even be a much more recent version which has AWK built in, since our version of GESHI is very old.

The latest stable version of GeSHi is 1.0.8.11, released on the 19th of Aug, 2012, but that version also does not directly support AWK.

We are running GeSHi 1.0.8.4 from 2009.

These GeSHi-based tags are good.

That reminds me that if we move off generic plain-ole-vanilla code tags to syntax highlighting tags like this, there will be a burden on all mods to tag correctly based on what kind of code it is.

This seems like a lot of extra work with little value; and since we are not a blogging site specializing in C# or CSS, for example, it would be too much work to try to heard cats and get each user to use the exact right codes tags for their code.

I'm not sure how to proceed; the main reason I moved down this path was to try to fix the scroll bar issue in the <pre> tags used in our code tags. This problem exists with all of this bbcode, so I am hesitant to jump down the rabbit hole on syntax highlighting at this time.

A higher priority is for me to purchase a new dedicated computer running modern Ubuntu and PHP7 and port the site over to that new site and get off this old hardware and depreciated PHP code.

I agree. I seem to me it would be best to just keep it as is, that is we ask the users to minimally use plain-ole-vanilla code tags for code and data and we just provide the highlight tags as an extra option for whoever wants to use it.

I think the plain code tags are preferable in most cases since its supports custom formatting which we regularly use as indicated earlier in the thread..
