UDL: Suffix Mode

[Eko palypse]

Ok, you are using npp 7.5.9 which means you should be able to use
Plugin Manger to install PythonScript plugin.
(Just keep in mind that if you upgrade to a newer (but still betas) version
there are a lot of changes in the plugin area!!)

Could you just copy and paste the example - makes it easier for me to use it for testing :-D

@Michael-Miller31

Eko has offered to create something for you (I think). It would be nice if you could give him some actual text – not just a screenshot – to start working with.

[Michael Miller31]

My apologies. I thought you were looking for something visual. Thanks again!

for index=1 to udim(ButtonNumbers)
	if Fkey==ButtonNumbers(index) then 
		let FnHasBeenPressed=1
		let OrderNumber$=OrderNumbers$(FirstOrderOfPage-61+index)
		if udim(Keys$) then
			let UniqueKey$=Keys$(FirstOrderOfPage-61+index)
		end if 
	end if
next index

Is it always a word which ends with $ or might it be that
non-word characters like minus underscore etc… are part of
the variable as well.
Basically I’m asking if a regex like \w+?\$ would do the job
or if it is needed to have something like \b.+?\$\b

@Eko-palypse said:

or maybe a better approach - what allows the language how a variable
can be defined

[Michael Miller31]

Always with $. The only time $ would ever be used in this language is to end a string variable.

[Eko palypse]

No, there is a misunderstanding, if I use \w+?\$
then a variable like UniqueKey$ will be colored but a variable like
Unique-Key$ won’t be.
If I know what the language allows, which chars can be used for a
variable name, then we can find the right regex to make this work.

[Michael Miller31]

String functions can also end with a $ but those I have listed as a keyword in my UDL with prefix mode enabled. Since every function begins with “fn”.

[Eko palypse]

Good to know - do you have a reference to the language you are using?

[Michael Miller31]

[Michael Miller31]

I can also give you the section from my userDefineLang.xml if it’s helpful

[Eko palypse]

So this is what we are looking for, right?

Do the following

• copy the script

• goto Plugins->Python Script->New Script

• give it a meaningful name and press save button

• paste the script into the newly ceated document

• save it

• open one of your BR! Source files

• click on Plugins->Python Script->Scripts->NAME_OF_THE_NEWLY_CREATED_PYTHONSCRIPT

If you want to know the details, let me know.

[Eko palypse]

btw, when it works like you want and want it to be available automatically
on every npp startup we need to create a USER startup.py but
I guess this can be discussed it the script is useful to you at all

[Michael Miller31]

Thanks for putting the time into this!

First, will this work on 64 bit N++?

I had some trouble finding a version of Python Script that was compatible but I managed to find a beta version.

also, I’m getting this error.

Traceback (most recent call last):
File “C:\Users\mmiller\AppData\Roaming\Notepad++\plugins\Config\PythonScript\scripts\create_strings.py”, line 4, in <module>

from _ctypes import Union, Structure, Array
ImportError: No module named _ctypes

[Eko palypse]

Yes, as I’m using x64 version as well.
Where did you download pythonscript plugin from?
Why didn’t you use Plugin Manager?
The official release channel for python script plugin is here .

[Michael Miller31]

I don’t have plugin manager so I went through http://docs.notepad-plus-plus.org/index.php?title=Plugin_Central .

Thanks for dealing with my idiocy. Going through plugin manager worked perfectly. Is there any way I can donate for your time?

@Michael-Miller31

Is there any way I can donate for your time?

yes, we urgently need 5 macbook pro’s. 👍
thanks in advance. 😂
