Pretty Tracebacks with links in PyCharm

[lucmos]

Hello,

I'd like to use the pretty tracebacks in PyCharm.

Currently, my traceback looks like this:

It's uglier than the rich's tracebacks, but it contains "links" that let the editor jump directly to the file and line in question.

Using rich, the path is still there:

But, it is not clickable anymore.

Do you know how can I make the links work?

---

There is a regexp in PyCharm that catches the pattern

print('File <path>, line <int>')

The line number is optional, e.g. this opens the file manager correctly

Unfortunately at the moment, I can't find a way to change the regexp or change the formatting in the rich output. Is there?

---

Adding the File keyword and some quotes is enough to make it work (correctly, even if the underlying is wrong)

Some terminals turn FILE:LINE in to a clickable link, but will generally not know how to handle Python tracebacks. PyCharm is obviously aware of Python tracebacks and knows how to extract path and link.

Unfortunately if I make it work in PyCharm, it would break clickable links in the terminal. I could be persuaded to add a PyCharm mode for tracebacks to get the best of both worlds.

BTW you might want to check the note in the docs about PyCharm, you may be able to get even prettier tracebacks.

Thanks a lot for the tip!

I think I'll open an issue on the PyCharm side, there is a problem with their regexp:

This is correctly recognized:

print('FILE:LINE')

This is not:

print('| FILE:LINE')

Is there any update? Did you create a PyCharm issue? If yes, I think it makes sense to link it here.

Btw other special characters, e.g.

print('\ FILE:LINE')

work fine. Only | seems to break the regex which is a pitty since rich uses | to create the nice frame.

Yes, I opened an issue on the Pycharm side some time ago

Thanks to lucmos' comment I was able to do a monkey-patch that can be placed eg in django's settings.py

import rich.box
import rich.traceback
from rich.panel import Panel


panel_init_original = Panel.__init__


def panel_init_fixed(self, *args, **kwargs):
    is_traceback_panel = "Traceback" in kwargs.get("title", "")
    if is_traceback_panel:
        box_pycharm_compatible = rich.box.MINIMAL_DOUBLE_HEAD
        kwargs["box"] = box_pycharm_compatible

        for arg in args:
            # handle rich code that passes Box as a positional arg
            if isinstance(arg, rich.box.Box):
                args = list(args)
                args.remove(arg)
                args = tuple(args)

    panel_init_original(self, *args, **kwargs)


Panel.__init__ = panel_init_fixed

rich.traceback.install(with=300)
