In order to browse Gemini sites, I use Elpher.
In order to get Gemini highlighting, I use Gemini Mode.
Once you have all three packages installed, visit this site, find a page you want to edit, follow the link to the “Raw text” at the bottom and then use
e to edit it. The raw pages are the only pages that can be edited. Use
C-c C-c to save, use
C-c C-k to cancel. Customize
elpher-gemini-tokens to set passwords, tokens, or whatever you need in order to edit sites.
Currently this only works on this site, I guess.
And I currently don’t have a markup rule to render Gemini links, but I’ll add that as soon as somebody posts one. 😀
Test it here: Gemini Test.
