error-links

error-links adds Google and Python documentation links to the bottom of exceptions.

In most terminals, you will need to hold Cmd or Ctrl to allow clicking the link.

This works really well alongside Rich's traceback handler, which is what enabled the highlighting and coloured output in the screenshot above.

Usage

To use this package, simply install it with python -m pip install error_links. Then, install the error links with

from error_links import install
install()

You can control whether to show the emoji or the text with the install keyword arguments use_emoji and show_text, respectively. For example, install(show_text=False) will use only the emoji for the link.

You can switch from Google to DuckDuckGo by specifying search_engine="duckduckgo". More search engines may be supported in the future if you make a PR or request it.

Install automatically

You can use the command error-links install to install error links automatically. This will modify the file sitecustomize.py in your directory site-packages.

To see where the installation was made, you can use the command error-links where.

If you want error links in the REPL automatically as well, you can read this article on how to run custom Python code on REPL startup.
