Debug: just doesn'to work

[BartolomeyKant]

I configured Debuger with target binary in my ~/.config/lite-xl/init.lua

config.target_binary = "absolute path to executable binary"

Pressing Debugger: Start Or Continue just doing nothing.

Hrm. Odd. That should work, but there's interplay with build and debugger if you have both installed (it uses your build targets to set target_binary).

If build's not working right now for you (based on the other issue), try uninstalling it and only using debugger; that may help.

Ok. I found the problem. I made a typo in config.target_binary and system.get_file_info had always return nil.

Now debugger started but if I add a breakpoint whole lite xl crushes.

Hrm. I don't use codeplus, could be something to do with that. Not sure. I'll look into it.

[BartolomeyKant]

I just remove codeplus and got the same error

No idea then. Could be a distinction between what lxl I'm running and your version (it should be functional on 2.1.5, but my main driver is the RC for 3.0).

I'll take a look.
