The only pitfall I see at the moment might be that your UDL name is not ml but something else.
When you run the script, do you see any errors in the console?
I assume you copied the whole script and not just the part you mentioned here, right?
If you click on the script from the Python script menu while holding down the CTRL key, will the expected script open in Npp?

Obviously I have more interesting things I will want to match, I’m just trying to get it working. I’m still not getting any highlighting in my test document with the hello and 12345. Maybe I don’t have the setup right?

An error has crept in here that

ml_regexes = [(0, (0, 0, 224))] = (r’\d’, 0)
ml_regexes = [(1, (224, 0, 0))] = (r’\w’, 0)

is not valid Python code, it must be like this

ml_regexes[(0, (0, 0, 224))] = (r’\d’, 0)
ml_regexes[(1, (224, 0, 0))] = (r’\w’, 0)

If you open the PythonScript Console, this should also appear as an error when you run the script.

Regarding match groups, we assume the following regular expression \d\d\d.
This expression returns at most one match if it can find 3 consecutive digits. If the expression were \d(\d)\d, the regex engine would produce two matches, the standard match of the 3 digits and a second match of the middle digit. This is reflected by the number in the regular expression. If there is a 0, the standard match, which is always present if something is found, is determined and coloured. If there were a 1, only the 2nd match would be taken into account. Of course, only if there is a corresponding regular expression, as in my second example.

Does that make sense?

In your comments I do not understand what is meant by “d = integer, denotes which match group should be considered” because I’m not clear on what a match group does.

I defined my own user defined language ml and then just tried to highlight letters in one color and digits in another. I followed your examples and now have the following in the file:

ml_regexes = _dict()
ml_regexes = [(0, (0, 0, 224))] = (r’\d’, 0)
ml_regexes = [(1, (224, 0, 0))] = (r’\w’, 0)
ml_excluded_styles = []
_enhance_lexer = EnhanceLexer()
_enhance_lecer.register_lexer(‘ml’, ml_regexes, ml_excluded_styles)

I saved the modified code as ml.py in the folder C:\Users\CS_laptop\AppData\Roaming\Notepad++\plugins\config\PythonScript\scripts

Then I made a new file to test with containing the following:
hello
12345

I set language to the empty user defined language ml.
Then I went to Plugins>Python Scripts>scripts> and selected ml.
This produced no result.

Please let me know where I have gone wrong. Thanks for your help.

You must have installed the PythonScript plugin, which you can do via PluginAdmin in the plugin menu.

Use plugins->pythonscript->new script and save it under a meaningful name. Copy the content from here into the script.

Save it. Now you need to define the regexes to add additional colours to the lexer. The script is commented, let me know if anything is unclear.

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.

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 ?

Hopefully this will be implemented soon.

my experience says this is rather “en attendant godot” or “warten auf godot” ;-)

I’ve opened two issues one here and one there to address this.

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.

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 ;-)

… the holy apocalypse and his fantastic 4 riders … 😂😂👍

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

starting from line 266.

omg … you are german speaking … that’s the last thing i would have expected … your name sounded so apocalyptically greek 😉

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

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.

(AFAIK, the accepted language of this forum in English.)

maybe one accepted language as we see more often :-)

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.

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.)

Normally I wouldn’t complain, except Chrome right-click Translate to English failed on this.
