UDL: Suffix Mode

  • Variables are currently in dark green. It would be nice if I could have a different color if a variable ends with a “$”.

  • 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.

  • 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

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

  • 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.

  • 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”.

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

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

  • 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.

  • 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

  • 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>
    import ctypes
    File “C:\Program Files\Notepad++\plugins\PythonScript\lib\ctypes_init_.py”, line 7, in <module>
    from _ctypes import Union, Structure, Array
    ImportError: No module named _ctypes

  • 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.

  • 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?
