I make an app for macOS that makes it easy to make offline viewers for documents like this (https://repla.app/). Would anyone be interested in having an offline viewer for this? E.g., being able to drag a `mindmap.md` file to the app icon, and have it render the mindmap and automatically update when you make changes in your text editor.

(I'm aware there are other ways to do offline views like this, happy to explain the relative pros and cons of Repla's approach versus others as I see them, if anyone is curious, just ask!)

View on HN

Yup!

Every time I see something like this, my thought process is:

“Cool, that could be useful for X”

“Hmm X is proprietary. I’m not typing into some random website.”

“Can I run this locally?”

“Nope, not natively. Is it worth my time to hack it?”

Down for this also. If you have a way to sign up for testers etc I'd be up. (Down, up, what is language? :) )

Definitely! There’s an email sign up at the bottom of the page here https://repla.app/

The app is already available to download and try, with a couple of interesting use cases you can read about on the site. We're also shipping a Markdown preview that's in testing now shortly. The next plugins we're looking at after that are Mermaid (https://mermaid-js.github.io/mermaid/#/) and now Markmap too.

This is such a cool idea...please let me know when it's in beta. I also highly recommend you submit it as a Show HN.

Thanks for the input! I'm also looking at supporting Mermaid diagramming https://mermaid-js.github.io/ I'd love to hear if people have other good use cases for this model, e.g., of having a plain text file you edit in a text editor accompanied by a rendered web document view of the same file.

Mermaid was the first thing I looked for. Looks very interesting. Will keep an eye out, congrats!

Main problem I've had using mermaid for large flowcharts is that the SVG gets cut off on the edges sometimes.

Mermaid can be plugged into Pandoc, so you can create decent PDF docs in Markdown that include diagrams. We store the Markdown files in git and have a Makefile that converts to PDF.

Yes. In fact, I was wondering if I could "just" run the REPL from the MarkMap website locally. Would make things a lot easier.
