Instructions and the script for https://www.youtube.com/watch?v=05wghiNzIj0

EWW - Emacs’ built-in browser is great for many things. Simple use cases include:

• Opening any file on GitHub/GitLab without having to download it
• Log investigation e.g., for GitHub Actions
• Reading PDF - link to a pdf doc opens it in pdf-tools (if installed)
• Bypassing a paywall

Zathura on Mac

I want to open PDF files with Zathura on Mac. Problem is - Zathura does not have a proper App Bundle. So you cannot go in Finder to a pdf file, navigate to ‘Get Info’ and set pdf files to be opened with Zathura.

Luckily, you can create a custom App Bundle that wraps up a script that does that

But that is not as straightforward as you think it is, you can’t just execute a shell script. What if the file already opened with one of the instances of zathura process? Since Zathura is not a native OSX app, it will create a new process instance every time you open it.

The following script opens a file in Zathura, and if it was already opened, it would only activate the right window.

It is possible to customize the behavior of org-insert-link, so for example when you insert a link in Org-mode (using C-c C-l) that is a URL to a GitHub issue or a GitHub PR, the description of that link automatically turns into the title of that GitHub item.

For the following snippet to work, you’d have to correctly set github-forge authentication. Which boils down to creating a personal access token on GitHub and adding the following line to your ~/.authinfo (or ~/.authinfo.gpg)

machine api.github.com login USERNAME^forge password TOKEN
