Range Comand of Numbers in UDLdidn't work

hans gerch

Hi Guys,
I’m working long time with Notepad++ and it’s a great tool. Today I’ve started do define an UDL for an internal used skript.
It all works fine until I want to define the Numbers…

The goal is to highlight all Numbers without 0 in RED

So Highlight all in RED (this is easy and was done by define the Style in the section Numbers)
Don’t Highlight 0 (that’s the hard one…)
I’ve used the Range to advice unsing only a special area, but wihtout sucsess. It seem to me that this command didn’t work anyway (see screenshoot of a test)

I’ve tried as well 1::5 or 1->5 like deskripted by Ivan (https://ivan-radic.github.io/udl-documentation/numbers/) but without sucsess
The other stuff like Präfix or Suffix works…

scond level would be If I would be able to have all Numbers in RED and the 0 in GREEN. I tried to use Keywords (like I’ve done it before for some comands), but It looks like this didn’t work with Numbers.

I hope someone can show me an easy solution for this

Thanks in advance

Hello, @hans-gerch and All,

The Range field ( Bereich ) is not intended to define the range of numbers

It’s just a kind of suffix-prefix symbol(s) which will be highlighted, like the numbers placed right before and, possibly, the numbers located right after

For instance, if that Range zone contains - :: __ ( a single dash, a double colon or a double underscore chars ), this means that, for instance, all the strings, below, will be highlighted in red

2-0.5
100::47
0.003__7.785
0000::

Now, I’m not very acquainted with UDL and I don’t see an obvious way to distinguish the digit 0 from the other digits ! I’m afraid that it cannot be do with the native N++ UDL feature.

However, you could use an enhanced UDL lexer, which could manage, differently, the 0 digit from the others. Two conditions :

Firstly, install the PythonScript plugin ( last version 1.5.4, using Python v2.7.18 )
Secondly, use the EnhanceUDLLexer.py Python script, created by @ekopalypse, from that post :
