TW and highlight.js

[Mohammad]

TW 5.1.15 uses highlight.js for syntax highlithing

The highlight.js contains some javascript files for language syntax highlighting. 

See: https://github.com/kookma/highlight.js/tree/master/src/languages

Some of them have bugs. My question here is for Fortran syntax highlighting the numbers are like these

 5
 5.23
 5.23e2
 5.23d2
 5.23_wp

So the number format (integer, float and user defined precision) is like below:

0-9
.
de
DE
number_followed by chars  (like 5.23_wp, 12_ip, 14.33e5_kp, etc)

In [$:/plugins/tiddlywiki/highlight/highlight.js] tiddler the number class is defined as below

{ className: 'number',
begin: '(?=\\b|\\+|\\-|\\.)(?=\\.\\d|\\d)(?:\\d+)?(?:\\.?\\d*)(?:[de][+-]?\\d+)?\\b\\.?',
relevance: 0 }

which is not correct (cannot recognize number like 2.34_wp) What is the correct regexp format for these numbers? Sorry, if the question is not directly related to TW! Best Mohammad
