Hello,
Ghostwriter is a wonderful piece of software and I found myself reaching for it to write gemtext for my capsules due to its similarities to Markdown. Would love it if official support was added for this.
You can find the specification here on Geminispace
gemini://geminiprotocol.net/docs/gemtext-specification.gmi
Or you can grab it from webspace
Increasing the number of supported input languages is a good idea; the problem is that Ghostwriter has difficulties exporting to a common format such as PDF without going through LaTeX or Context.
We really need to get the basics right in this area before making the editor any more complex.
Adding gemtext as an input format is about the editor/renderer, not export. It’s actually simpler than Markdown (no inline formatting, just line-based), so it should be a lighter lift than the existing Markdown support. The export issues are real but they’re a separate workstream.
