Calltip on mouse-over from UDL xml file (Python)
-
@Alan-Kilborn Thanks for the reply
I wouldn’t know to be honest. I haven’t used Python that much before. Its not only line breaks though, at the moment it shows the text in brackets too. Picture below also shows the dictionary created with ElementTree not respecting the order of the XML.

You shouldn’t be using the default Python language stringification of the data structure element as the popup, if you want the string to be user-friendly. You should be extracting the elements from that sub-object that are useful to you, in the order you want them to appear, using one of Python’s string-formatting techniques. (That’s nothing specific to Notepad++. Any time you want to take data from an object and present it as a string in Python, you need to format the string to make it look like you want – and if you need help with that, it’s not really a question for here, because that’s generic programming help, not Notepad++ specific.)

@PeterJones Thanks for the reply and the advice
I understand that my questions after my initial post are not directly related to Notepad++ anymore. But these nudges in the right direction I got from you is all that I needed,I looked into string formatting, and got a step further. Currently it shows only the description of a keyword as calltip, and it only works if there is only 1 Overload entry. I’m going to check how to make it work with multiple hint definitions and the up and down arrows.
I included a picture and the test.xml as an example in case someone wants to use the script in its current state. All text will be wrapped at max 90 characters, and as stated in the Notepad++ documentation for line breaks use

<NotepadPlus> <AutoComplete language=""> <Environment ignoreCase="yes"/> <KeyWord name="ActivateAnim" func="yes"> <Overload retVal="" descr=' 
------------------------------------------------------------------------------------------ 
Plays the specified anim at the specified priority and weight, with optional parameters. All arguments except the sequence path are optional. This is a low-level animation function that must be used with care. Use BlendToAnim to deactivate or transition the animation to a different one.

I’ve decided to go with only 1 “Overload” entry per keyword for the time being. I couldn’t find any clear documentation or examples on how to implement them, if anyone has any experience with this… I’m all ears. Unless its to add multiple overloads, this will be the “final” version of the script. A bit funny that it turned out to be “on character” and not “mouse-over”… :)
Something weird I noticed while testing with the multiple overloads, when the calltip is showing and I use the “alt up” and “alt down” shortcuts it crashes Notepad++ to desktop. Even with the script below that only has 1 “Overload” entry it CTD, clicking on the calltip doesn’t crash btw. I have no idea why it does this, I disabled the parameter hint shortcuts, and recommend it to anyone who wants to use the script below until the cause is found.
I changed the script to work on a “space” instead of mouse-over, but it can easily be changed to any character you want. I added explanations in the comments on how to edit the script to work with any User Defined Language, and how to change the character that triggers the calltip. Formatted the calltip some more and cleaned the script up, if anyone needs help to get it running… don’t hesistate to ask.

I had some free time and had another go at multiple overloads, but there seems to be a bug with the down arrow in the tooltip / and the alt+down shortcut combo when using PythonScript. Obviously there is nothing wrong with the standard implementation of this feature, only when creating a custom tooltip with PythonScript does this CTD happen.
I did a small test with the SCINTILLANOTIFICATION.CALLTIPCLICK and this was the result, position 0 is clicked anywhere but the arrows, position 1 is clicked on the up arrow and position 2 should be clicked on the down arrow… but this results in Notepad++ crashing to desktop.

@Khundian-Twitch ,
Just a note, and I’m not sure if this is relevant with what you’re doing with pythonscript, but the calltip functions are triggered by a delimiter insertion, meaning when you type the keyword, and then click a parens if it is the opening for a function, then the calltip pops up, and you have to use the mouse to click the buttons up or down.What you’re doing, may not make what I just mentioned relevant, since it sounds like you’re past my knowledge, but I thought I might mention in in case it is relevant.

Exits with
Exception Code: c0000094
which is a division by zero code. Seems the
positionkey cannot return a value2as it fails to get a value.Also a second error
Exception Code: c000041d
A STATUS_FATAL_USER_CALLBACK_EXCEPTION code.
This is what I tested with:
from Npp import console, editor, notepad, SCINTILLANOTIFICATION try: callback_registry except: callback_registry = [] calltip_wrap = ['\x01 one\n\x02 description', '\x01 two\n\x02 description'] if not editor.callTipActive(): editor.callTipShow(editor.getCurrentPos(), calltip_wrap[0]) def calltip_update(args): console.write(args) pos = editor.getCurrentPos() if editor.callTipActive(): if args['position'] == 2: editor.callTipCancel() editor.callTipShow(pos, calltip_wrap[0]) elif args['position'] == 1: editor.callTipCancel() editor.callTipShow(pos, calltip_wrap[1]) return True if 'calltip_update' not in callback_registry: callback_registry.append('calltip_update') editor.callback(calltip_update, [SCINTILLANOTIFICATION.CALLTIPCLICK]) -
@mpheath Thanks for taking the time to test, reply and clarify the issue.
I guess I’m out of luck. I wonder if it’s something with the PythonScript plugin, when I have some time I’m gonna test with the LuaScript plugin and see if the same happens when creating a calltip. -
I tested with the LuaScript plugin and exactly the same happens, I guess it has nothing to do with either Python or LUA plugin. I guess its a bug in Scintilla or Notepad++. I’ll post the LUA code I used to test below.
function showcalltip(ch) calltip = "\001 <Click> \002" pos = editor.CurrentPos editor:CallTipShow(pos, calltip) return false end function printclick(flag) print(flag) return false end print("Test script running.") npp.AddEventHandler("OnChar", showcalltip) npp.AddEventHandler("OnCallTipClick", printclick) -

A crash is a pretty big deal; someone should open an official bug report on github.

I agree, but I’m not sure if this qualifies as a bug in Notepad++?
The standard implementation of using the arrows to cycle through multiple overloads works fine. Its only when a user starts tinkering with script plugins and creating their own calltips that this crash will occur. -
I created a bug report on github, guess we’ll see if it qualifies as a bug. Link to report
-
@mpheath Seems it was something in the Notepad++ code, but solved very quickly by the guys on github. Without a doubt the debug info you provided had something to do with that, Thanks again! :)
-
@Khundian-Twitch Well done! I tested the artifact in PR #14667 that solves the crash issue and so now position
2is possible for the down arrow of the calltip. -
I have finished the script, if anyone is interested I posted it in the Plugin development forum.
Thanks again to everyone who helped me out!
