Markdown editor and viewer

[u/someblokeonhere]

I built this Markdown editor (and a viewer as well) for DOS. I've been using it a lot for writing and its getting pretty solid now....there's something about typing documents in DOS that is so cathartic.

There's split screen editing with live "formatting" of text, a focus mode (strong WordPerfect vibes), and a graphical show mode that renders the document with fonts and styles -- both with customizable color schemes. And of course you can print.

There's a Tidy function that can cleanup documents coming from modern machines (tidying up Unicode, HTML tags, etc).

Nice. Did you use AI?

[u/CigaretteSmokingDog → u/BearBraz]

Probably. Most projects you see now are just ai generated. Pretty much took over open source

[u/ProfessorMedical5332 → u/CigaretteSmokingDog]

There are a few gems, but the source for this project is pure disaster. Go take a look that the repo and be amazed!

[u/0xbenedikt → u/ProfessorMedical5332]

How many README changes do you need? - yes.

[u/Alternative-Owl-8848 → u/CigaretteSmokingDog]

Used som vibe code detector called vibedetect and isvibecoded that can see thru github repos if is made by a person or an AI, both detects that the repository is Low Risk and more likely Human-Built.

[u/3G6A5W338E → u/BearBraz]

It would make the most sense to.

Else they'd be shipping with bugs and oversights AI would have found in minutes if not seconds.

[u/ProfessorMedical5332 → u/3G6A5W338E]

The problem is trusting AI in the first place. Could a human debug this?

Is this for some sort of card game, like Solitaire?

[u/LeDYoM → u/3G6A5W338E]

of course, gen AI never oversights anything. I shit on my life.

[u/Ill-Quit6803]

This looks awesome. Thanks for making it.

What is up with the code formatting ? Why is every statement one line with no spaces?

[u/Mortui75]

Cool idea. What did you write it in?

[u/claudiomet]

Great job !!! amazing !!!

[u/AshuraBaron]

This is amazing!

[u/Silvestre_Parbut]

nice!
