space-shooter.c VS NetHack

You can do something like this, but way less polished and stick to one platform: https://github.com/tsherif/space-shooter.c/tree/master

Otherwise study real, mature, well-written C programs. There's a wealth of techniques and tricks that aren't really documented anywhere, but rather picked up from others. Recommendations off the top of my head: BSD utilities, musl, and SQLite. Or simply study the source for your favorite C software. Also, something good posted here recently: The Architecture of space-shooter.c.

I wrote space-shooter.c as a personal challenge to create a game from start to finish in C without using any 3rd-party libraries and wanted to share the source as a reference for anyone who's also interested in this type of game programming. The source code is heavily-commented, and I'm also writing a (still WIP) architecture guide that goes over the design decisions and details I learned about working with OS APIs in C: https://github.com/tsherif/space-shooter.c/blob/master/ARCHITECTURE.md

My configuration of Eglot is simple: (use-package eglot :hook (c-mode . eglot-ensure)). And it works for a single c file. But when I use this setup to read the code of NetHack, it doesn't work for linting and definition finding (M-.), even though eglot connection has no problem. I observed the same problems when reading the code of SQLite. Some specific problems I observed:

Since nethack 3.1.0, the source for nethack's "bestiary" has been dat/data.base, in plain text, processed into a file named "data" when building the program. The unprocessed file intended for the nethack's next version can be seen at https://github.com/NetHack/NetHack/blob/NetHack-3.7/dat/data.base (it's quite long).

I am not really 100% sure what you are looking for. Are you looking for the actual picture? It is built during compilation from this uuencoded file https://github.com/NetHack/NetHack/blob/NetHack-3.7/win/win32/splash.uu

xNetHack is based on NetHack 3.7.0, and there was a bug (now fixed) in NetHack 3.7.0 that caused stair destinations to be messed up after a game is recovered. I wonder that has happened here: perhaps you are playing a version of xNetHack that inherited the bug from NetHack 3.7.0, this is a recovered game.

They won't be afraid of music in 3.7.

This is a bug that was fixed in the upcoming 3.7, in this commit. Basically, if the random filler created a space that was made inaccessible by the fixed level design getting overlaid on top of the random filler, a door could be created to make that space accessible.

There is not a comprehensive list of changes in existence. This one comes close but doesn't contain everything https://github.com/NetHack/NetHack/blob/NetHack-3.7/doc/fixes3-7-0.txt

I have an open github issue requesting that intrinsic invisibility be made only temporary, not permanent. That would make the invisibility mechanic more interesting since you could decide multiple times per game whether you want it, and extrinsic invisibility items would become more useful.
