I recently noticed that better_errors allows you to to
open files from within your favorite editor
Show archive.org snapshot
. However it was not so easy to get rubymine:// links to work on Gnome/Linux. Here is how it finally worked for me:
Step 1: Add a Desktop launcher Show archive.org snapshot
Add this file to ~/.local/share/applications/rubymine.desktop:
[Desktop Entry]
Version=1.0
Type=Application
Encoding=UTF-8
Name=Rubymine
Exec=sh -c '/snap/bin/rubymine ${0#"rubymine://"}' %u
Terminal=false
StartupNotify=false
Categories=Application;
MimeType=x-scheme-handler/rubymine;
Note the Exec madness:
- You might have to adjust the path to match your executable (
which rubymine) depending on how you have installed rubymine - RubyMine does not know how to handle arguments like
rubymine://Gemfile. We have to strip the protocol - The
rubymine://prefix is thus stripped from%uusing some weird shell parameter expansion Show archive.org snapshot syntax
Step 2: Map the rubymine mime type to the new launcher
Add the following to ~/.config/mimeapps.list:
x-scheme-handler/rubymine=rubymine.desktop
Step 3: Test your desktop entry
- Does
gio mime x-scheme-handler/rubyminesuggestRegistered applications: rubymine.desktop? - Does
xdg-open "rubymine:///etc/hosts"open the hosts-file in RubyMine?
Step 4: Tell better_errors to use your opener
The BETTER_ERRORS_EDITOR_URL Show archive.org snapshot environment variable can be used to tweak better_errors:
export BETTER_ERRORS_EDITOR_URL="rubymine://%{file_unencoded}"
Step 5: Try it out!
Restart your server (in a new terminal!) and add a raise statement to your local application.Does better_errors link to your file system?
Make sure that better_errors is at least on Version 2.9 or newer, the BETTER_ERRORS_EDITOR_URL variable was introduced in 2020.
