Support on file link format

[FlorentTorregrosa]

Hello,

I am testing drupal-debug on my personal stack and wanting to use all the features of the pretty exceptions, in my drupal-debug.yml I have set:

file_link_format: phpstorm://open?url=file://%%f&line=%%l&/project/>/home/florent/sites/docker-drupal-project-d8/

After finding the syntax and seing that as I am not directly on the host (actually in a Docker container), I added the substitution from VM path / host path.

I have three questions:

1. Could the VM path (/project/) be handled in an environment variable?
2. Could the host path (/home/florent/sites/docker-drupal-project-d8/) be handled in an environment variable or even more dynamically?
3. Now I have links in my exception trace like phpstorm://open?url=file://%/home/florent/sites/docker-drupal-project-d8/www/sites/default/settings.php&line=%39 seeing #69, I know understand the discussion about '%' escaped at the Drupal Developer Days, but even if I remove the '%' part in the link, the link won't open the file in PhpStorm. I have went through stackoverflow, JetBrains issue tracker and old blog posts (can't find recent ones), it seems that there was an option in "Tools > Create Command-line Launcher" (http://davidbu.ch/mann/blog/2014-05-06/open-php-stack-trace-links-phpstorm.html) and now it seems that this option is only available if you have installed the Jetbrains Toolbox, unfortunately I have installed PhpStorm using Snap. So my question is: is it still possible to open the file in PhpStorm? If yes could you give me a clue about that please?

And a last remark, maybe documenting a file_link_format as example to guide newcomers would be good. Yes after a quick search you can find it, but also as this project is to improve DX, having that set out of the box (if possible) should be good.
