nvi2 VS pegasus-frontend

nvi2 [0]: I got to like the simplicity of nvi when installing Void Linux on my laptop, but it had some annoying bugs that made me switch to nvi2. In general, it feels like `good' software; powerful enough by virtue of being a 1:1 vi clone with a few crucial improvements (multibyte, multi-undo, etc.), but simple enough to hack on if I miss some feature. Though no autocomplete means it's not suitable for more verbose languages, like Java.

QuickJS [1]: qjscalc is my go-to scientific calculator, and qjs my go-to JavaScript implementation for simple programs. The C interface is very nice to use, too. All in all, it feels very much like a "complete" engine, even if not quite as fast as one with JIT.

w3m [2]: Somewhat lacking as a web browser, but a very good pager. Would take it over less any day. Also has the best table display of any text-mode browser, supports inline images, and is rather extensible.

Wine [3]: It's gotten so good that I no longer have to dual boot Windows. Still not perfect, but definitely on my list of "good software".

Don't confuse OpenVi/OpenBSD-vi, nvi1, and nvi2. These are all different programs that share the same heritage.

OpenVi is derived from OpenBSD vi, which derives from nvi version 1.79, released in 1996. There has been 25+ years of independent development as part of the OpenBSD base system and has diverged greatly in that time, with the development going in a different direction.

Nvi1, currently on version 1.8x, is maintained at https://repo.or.cz/nvi.git - I believe the latest version of this editor does have multibyte support, but this is not the OpenVi/OpenBSD version of the editor.

Nvi2 shares heritage as well but also, quite far removed from the original code, is actively maintained at https://github.com/lichray/nvi2 and also includes multibyte support.

(IIRC) the multibyte support in both Nvi1 and Nvi2 derives from nvi-m17n, developed as part of the KAME project by the late itojun - http://www.itojun.org/itojun.html ... the last update to nvi-m17n was about 3 years ago, and is available at https://cgit.freebsd.org/ports/tree/editors/nvi-m17n/files

Currently, optimizing for size using link-time garbage collection with GCC 11.2 on an x86_64 glibc Linux system gives a good idea of the changes over time and the different direction these editors have taken. OpenVi is also simplified in structure and does not have the three levels of abstraction of Nvi 1.8x - there is no library interface layer.

For OpenVi, the compiled binary is 280K, and for Nvi1 (nvi-1.81.6-45-g864873d3) the compiled binary is 528K (36K for vi, 528K for libvi).

OpenVi has a single configuration standard with no dependencies beyond curses.

Nvi1 has many options beyond trace/debug ("widechar" "gtk" "motif" "threads" "perl" "tcl" "db3/4" "internal-re") - so at least 255 different build variations are possible.

(I've not yet built Nvi2 myself on Linux so I can provide an actually fair comparison yet, but I will, and I'll summarize the data in an FAQ section of the README)

Nvi1 (https://repo.or.cz/nvi.git) looks like:

You could try this front end. https://pegasus-frontend.org/

Have a look at pegasus-fe. Works on most OS (windows, macOS, linux, android etc.). It won't download games, but presents them in a very nice and efficient way. It also has many themes. Lastly, you can also launch programs, not only games !

Pegasus - seems like a proper launcher that can incorporate games from multiple stores? It seems promising.

Pegasus

I'm looking to create an emulation front-end (like Launchbox, Playnite, and Pegasus) using neo4j to store relationships between items (games, platforms, developers ect.). I've built myself a starting point in Java using JavaFX, but after trying to display items I'm starting to experience the limitations of that. I'm wondering if it might be a good idea for me to switch over to Unity at this point in development, before the application gets too big.
