UDL 2.0 in Notepad 7 release



  • Hi, I have been waiting more than 2 years to this new release wishing a new UDL version… but we have again udl 2.0 :(

    2 Years ago inside sourceforge forums I have been trying to fix some problems… to be able to configure it to support ADA syntax during various posts we saw that UDL cannot support languages like ADA… I even tried with special configurations but then we discovered a bug in code folding with CR LR that was breaking code folding…

    Is there any plans to release UDL 3.0 or UDL 2.X ?? is UDL totally dead ?

    Many thanks Notepad++ is great :)



  • @Jose-Manuel-Vela-García

    not sure if this solves your issue but current release is UDL 2.1.0.12
    But may I ask why not using builtin ada langauge support?

    Cheers
    Claudia



  • Built in ADA does not support various things I want:

    1. Precompilation
    2. Function list
    3. Code folding
      etc…

    It only support “colours” nothing else…

    In my custom ada colours, precompilation and function list are working… but code folding is not possible because of UDL is weak against ADA syntax…

    :(



  • @Jose-Manuel-Vela-García

    as I don’t know ADA, could you provide an example code,
    with hints what should be done for each feature?
    Also your custom ADA UDL would be helpful, I guess.

    Cheers
    Claudia



  • You can check the posts about this topic in sourceforge old forum:

    Many thanks.



  • @Jose-Manuel-Vela-García

    do you still use two round brackets in delimiter1?
    If so, can’t you use just one - seems to solve the type TYPES issue.
    In regards to windows/linux eol - what about a solution like

    • when file gets modified first -> change to windows eol automatically
    • when file gets saved (well, before, in reality) -> switch to unix eol.

    This would involve python script plugin. Let me know what you think about.

    Cheers
    Claudia



  • I am using for delimiter 1:

    Open:
    ((type subtype))

    Close:
    ((EOL))


    About the eol bug with that script If I understand well… once u press save it will be saved using original format right ? if so then sounds good for me.

    Many Thanks for the support !!!



  • @Jose-Manuel-Vela-García

    did you try using delimiter 1 with a single bracket configuration?

    Open:
    (type subtype)

    Close:
    (EOL)

    as it looks like it solves the TYPES issue you mentioned.

    In regards to the script - I will post it later this day.

    Cheers
    Claudia



  • @Claudia-Frank,

    What’s the difference betweeen the double-(()) and single-() grouping operators? The UDL 2.1 documentation at http://ivan-radic.github.io/udl-documentation/delimiters/ describes the double-(()) version, but not the single-() version. Is it documented someplace else?



  • @PeterJones

    the truth you want the truth, well - no idea.

    I didn’t check the source code yet - found it by trail and error and
    still don’t understand when and how it is working but from the examples
    (sourceforge thread) provided I see that this might be a solution.

    Cheers
    Claudia

    if you haven’t already installed the python script plugin, then please
    install it from here instead of using
    the plugin manager.

    The script looks like this

    I hope the comments are clear, basically, every time you open a new file or you switch
    a tab it get’s checkd if the file is an ada file by checking it extensions (see code).
    If it is and you start modifying the code it checks if windows eol is used and if not
    script sets it. If you save the file, it gets checked what the original eol was and then it
    resets the eol.

    If you create a new script with name startup.py and put the content into it
    and you change the python script configuration from LAZY to ATSTARTUP, then
    the script gets automatically executed every time you start npp.

    If you create a new script with a different name, you need to execute it manually once
    every time you start npp.

    Let me know if something is unclear.

    Cheers

  • @PeterJones

    Peter, now I know why it worked because type and subtype is also configured
    as keywords. So my workaround seems to be non-working, just another
    coloring rule is active.

  • I have added today the python script and seems that is not solving the problem :(

    I have upload a video example of the real problem… the bug u can see in the video is totally random… in any sentence suddenly tha open/close folding mark just is in a wrong place… and just creating new lines it auto fix it… and when you remove those new lines again the mark keeps in the correct place… so strange…

    Video url --> https://youtu.be/xZZxKMRjU0w

    Many thanks !!!



  • @Jose-Manuel-Vela-García

    the script itself doesn’t do any folding operations it just modifies the eols.
    So the bug seems not to be solved by using windows eol therefore
    the script isn’t helping either.

    Unfortunately there is no way python script can interact with lexers in
    a safely manner.

    Cheers
    Claudia



  • So is there any news about “udl 2.0” or anyway to fix this ??





  • About UDL3 status is there any ETA ?? Will be any UDL3 Beta ?

    Many Thanks for the doc and info !!



  • No status as far as I know and no timeschedule. Maybe in your case it makes sense to checkout https://sourceforge.net/p/scintilla/code/ci/fba1e8c31818fc1b38fc1b1ba3a200f40ef568f9/log/?path=/lexers/LexAda.cxx and checkout for an update there as scintilla is the basis for n++, but the update cycle of scintilla for n++ is quite slow.



  • There are no code folding / function list support at all in scintilla or notepad++ that’s why I am trying to do it by myself using the “user custom lang definition” and udl but udl is useless with ADA :(.

    Would be nice if udl3 fix this kind of problems… But I am not sure after these years if udl3 will be realease any day…

    Thanks for the info.



  • ADA is not the only reason for UDL3. Generally UDL’s generally don’t work well with different themes and UDL3 is said to help with that, too: https://sourceforge.net/p/notepad-plus/discussion/331754/thread/bd2bc405/#757b
