How to debug a Python extension?

[lduperval]

Howdy y’all,

I’m trying to add a feature to the Linguist extension. I added a new command, but when I try to execute it, nothing happens. It’s likely an error somewhere in the code I added, but I can’t figure out what’s wrong.

Is there a logfile somewhere (on Windows) that stores output created by the Python script? That way, I can put print() statements to see what’s happening.

Otherwise, how can I create a popup so if there is an error, I can show it on the screen? Or se the popups to track where I am in the script.

Thanks!

Hello,

As for a log file, I have been using this for a while now → How to catch libreoffice macro errors and forward to a Python log file?

There are also console methods:

Launch Python Console to Use From Macro

Can I run code in a python macro and print output to a console? I’ve tried the following code based on the links it contains. This code does not print to the console: # https://help.libreoffice.org/latest/bo/text/sbasic/python/python_shell.html#N0127 def interpreter_console(): import uno, os, subprocess ctx = XSCRIPTCONTEXT.getComponentContext() smgr = ctx.getServiceManager() ps = smgr.createInstanceWithContext("com.sun.star.util.PathSettings", ctx) install_path = uno.fileU…

Failing to shell 'Python interactive console' from Basic under Linux

The following code operates fine under Windows but fails under Linux: Sub interpreter_console ps = CreateUnoService("com.sun.star.util.PathSettings") install_path = ConvertFromURL(ps.Module) Shell( install_path + GetPathSeparator() + "python" ) End Sub Note that the shelled pgm file exists, and that same pgm argument runs fine from the OS terminal. Same observations with this code: Sub Main flags = com.sun.star.system.SystemShellExecuteFlags ps = CreateUnoService("com.sun.st…

Python script unable to print to console in libreoffice-gtk3

Hi You can get extra information from Input/Output to Screen with Python wiki page. However your Python script will somehow need to identify the runtime context, which means being able to distinguish the shell from libO GUI, if you want your script to run in both contexts.

Thanks, I should be able to figure it out with those links!
