Count me as interested in a terminal that supports “infinite” scrollback, while keeping memory usage deterministic. Apply color styling heuristically based on content is interesting. I’m assuming this only kicks in if color is not applied inside the term? Being able to cat an xml/json/source file and get decent styling sounds quite cool. Also hard.
You might want to setup a non-github landing page. While you certainly can use github for anything (within their tos), user expectations are that open source tools are hosted there.
Spin up a quick landing site (even just use something like squarespace) and capture some animated gifs showing your distinctive features in action.
I agree that you’ll have a hard time selling this as a product - there are too many “pretty damn good” versions of terminals to get folks to pay.
Have you thought of offering an embeddable component? I can imagine a number of great uses for a lightweight, native, customizable text control with the features described. I think we’re reaching peek Electron, and fully baked native text control/editor would be a differentiator.
Perhaps offer the terminal for free and commercialize the component?
Either way, HN is a tough crowd, especially with commercial products, so don’t take it to personally.
Take the constructive part of the criticism and pursue your passion.
