NetHack VS angband

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).

Oh jeez, this fixes CVE-2023-24809 - i.e. nethack on shared systems may be risk due to buffer overflow in pre-3.6.7 versions.

I was looking at the list of diffs with some confusion about why it's such a small point release ( https://github.com/NetHack/NetHack/blob/NetHack-3.6/doc/fixe... ) before I re-read the release notes and saw the security issue.

For NetHack, part 1 comes up quite frequently because people like to port the game to new platforms / user interfaces, so there's a "windowport" system which exposes interfaces for gaining information about what the player can see – all the game's UI routines go through a small set of functions, which can be swapped out by recompiling the game (or you can even build NetHack as a library nowadays, so that you can link your own user interface against it). If you wanted to intercept part of the information about what the player could see, the easy way would be to modify an existing windowport to see that information and pass it to your interception tool (although this would require changing the game's source). If you were really set on not changing the source at all, you could probably use some sort of debugger API to intercept calls to the windowport, but changing the source is probably easier.

Tangentially related, this repo contains one of the greatest games ever made in C and once you have your feet wet would be very educational to look over.

Rogue, nethack, and Abuse come to mind, and then pretty much all the old id software stuff, along with the raven engine. These SDL tutorials might be of interest to you too, they are basically in the format of game sources with detailed explanations.

Congratulations! The dev team did something about your request. It's not what you wanted though.

Angband - Roguelike Dungeon Crawler. C

And it worked, it downloaded and installed angband however with a font glitch that can be resolved with a command I found from ( https://github.com/angband/angband/issues/4575 )

Broge, Angband, C:DDA, Dungeon Crawl Stone Soup, are some options.

Angband

There is a way to get many people contributing and collaborating to a single project over extended periods, even as individual people come and go. That way is called free and open-source software. See e.g. Dungeon Crawl: Stone Soup, Brogue: Community Edition, Angband, Cataclysm: DDA.

It's notable that a big reason that Angband has a large number of variants is because a lot of its data is in easily readable, editable flat text files. For instance:

https://github.com/angband/angband/blob/master/lib/gamedata/...

This allowed people to start work on variants without having to write C or even recompile. Also, Angband's source code has a reputation for being pretty clean and easy to understand and modify.

Oook. The original link went straight to Github and was date gated. For the sake of posterity: [0].

Since this project doesn't seem to have been discussed on HN before, I've switched the URL from https://github.com/angband/angband/releases/tag/4.2.2 to the main project page.
