Enhance UDL lexer
-
Der Source Code zu UDL ist hier einzusehen.
Aber das Problem liegt bei mir.
Ich habe comment style id und comment line style id verwechselt.
Es muß genau anders herum sein1 = comment style 2 = comment line styleSorry, verdameleite …

English, anyone?
Normally I wouldn’t complain, except Chrome right-click Translate to English failed on this.
-
-
I’d say the burden is on posters to post in English, not others to translate later. (AFAIK, the accepted language of this forum in English.)
-
Manager summary :-)
I failed at the documentation by stating that comment style is using id 2 and
comment line style is using 1 whereas it is exactly the opposite. -
(AFAIK, the accepted language of this forum in English.)
maybe one accepted language as we see more often :-)

But thanks, @Alan-Kilborn,
Chrome used to be my backup browser, but I’ve recently switched to it being my primary, and I didn’t know there was an easy RClick>Translate option in Chrome. When I ran it on the German on this page, it translated okay for me. (Which is good, because my 2 years of highschool German from more than a quarter-century ago just didn’t cut it.)
But I do agree that the forum’s default language is English, and if people want help here, they should at least provide the translation for us. I understand that some of the posters might be more comfortable (or equally comfortable) in German; and it’s fine for someone fluent in German to answer in German; but also provide a translation to English, so the other people who read this thread – both for those who have started to help, and got lost when it switched language; and for those who come here searching for a solution to a similar problem, and find that the actual answer is buried in another language, when it started in English.

In the source code I find the place where the numbers are assigned or do not arise.
I would like to find that to be able to understand it.
Then the template would have to be adjusted. -
Ok, :-D
the outcome of the discussion is that I need to post another version of the script
which hopefully adresses @guy038 findings as well,So dear future reader,
if you have read until here - forget about everything you read and hope that you will find
a new version of the script as another post after this one.
:-D -
omg … you are german speaking … that’s the last thing i would have expected … your name sounded so apocalyptically greek 😉
-
starting from line 266.
-
well my name is eren and a nickname is eko.
And you are absolutely right about apocalypse.
In my first week at work, everyone learned that I could be called eko.
At one time I did something terribly wrong which lead to an failure of the
whole production system. My colleague said something like
“this must be the feeling when the 4 apocalyptic riders arrive” and another one
managed to make eko and apocalyptic to result in ekopalypse.
So here comes the ekopalypse :-D -
thanks for the insight, @Ekopalypse
the combination of all, name, mishap at work, and this community, gives way to a perfect book title:… the holy apocalypse and his fantastic 4 riders … 😂😂👍

LOL :-D

In order to be able to solve the issue about scrolling the second editor
instance and having styling in it, it is needed to have a way to identify which
scintilla instance sent which scintilla notification.
This can be achieved by using the SCI_SETIDENTIFIER as described here.I’ve opened two issues one here and one there to address this.
Hopefully this will be implemented soon.The issue about zooming and word wrap, actually it is a word wrap only issue,
should be solved with this version, also the documentation fix is implemented ;-)# -*- coding: utf-8 -*- from Npp import editor, editor1, editor2, notepad, NOTIFICATION, SCINTILLANOTIFICATION, INDICATORSTYLE import ctypes import ctypes.wintypes as wintypes from collections import OrderedDict regexes = OrderedDict() # ------------------------------------------------- configuration area --------------------------------------------------- # # Define the lexer name exactly as it can be found in the Language menu lexer_name = 'BR!

I don’t mean to be a debbie downer but good luck with the “there” one. The “here” one is much more likely to happen, although it seems that even PS development has slowed way down after being encouragingly active for a while.
-
Hopefully this will be implemented soon.
my experience says this is rather “en attendant godot” or “warten auf godot” ;-)

@Ekopalypse
What is this script for, please ?
I have come here, because I was looking up existing Notepad++ issues, have found this https://github.com/notepad-plus-plus/notepad-plus-plus/issues/7622 and followed a link in a comment pointing to here.My problem is that I am trying to configure a UDL in Notebook++ for Jenkins Pipeline syntax,
but the UDL lexer in Notepad++ does not find and colour string “stage” if there is “stage(”.Can I use your script to replace the Notepad++’ lexer ?
BR
Rainer

If this is still an issue for you, let me know.
The idea of the script is to enhance the existing UDL
with coloring which otherwise isn’t possible to do
with the builtin lexer, means, script, normally,
runs together with the UDL lexer. -
I found this and am quite interested in it but am not sure how to implement this. I’m an engineer not a CS so my programing is only fair. Can someone tell me how to actually use this in notepad++ or where to go to read what I will need to get it going? Thanks
