This includes the following changes: - Move the data type wrangling into the lib to make it easier to use - Put the functions into their own `zlib` namespace - Use ErrorOr instead of exceptions - Error codes for compression/decompression

 Don't use excessive comments, use descriptive names instead.
 There is no such thing as too long names (within reason, of course).
 Don't have comments that go beyond 80 characters per line, preferably
 slightly less.
 Put comments on their own lines.
 Format comments to improve readability, don't have long single-line comments.

BodgeMaster	53173dd7c7	lib/zlibutil, tools/zlibutil: moving things around This includes the following changes: - Move the data type wrangling into the lib to make it easier to use - Put the functions into their own `zlib` namespace - Use ErrorOr instead of exceptions - Error codes for compression/decompression	2024-06-10 06:29:30 +02:00
BodgeMaster	8482194b01	build system: update build commands for libs I forgot this after changing the build system when resolving merge conflicts.	2024-06-08 23:59:55 +02:00
BodgeMaster	229392a7fe	test/zlibutil: update to match changes in zlibutil, increase reliability The following changes have been made: - The test has been adjusted to zlibutil's changed behavior. - The output of zlibutil isn’t checked against static data, instead it hands the compressed file to another decompressor. This was done because the exact output can change with updates to zlib itself (this appears to have happened in my case). - The new test works with random data, reducing the likelihood of false passes. - The new decompression test works with its own file for the same reason.	2024-06-08 15:59:03 +02:00
BodgeMaster	a48c4dcd33	tools/zlibutil: Change CLI to act more like other compression utilities Compression is now the implied default action, decompress with the -d flag.	2024-06-08 15:10:38 +02:00
BodgeMaster	a787a89493	resources/region_files: add a zlib compressed chunk	2024-06-08 15:09:14 +02:00

BodgeMaster	8f8d51f459	lib/net/*: Move stuff around I did this months ago with the intention to finally start implementing networking.... Yeah, that definitely panned out. Also, Git is drunk with how it says files have been renamed, they’re just empty apart from the license notice.	2024-06-08 15:07:26 +02:00
BodgeMaster	8b13f72acc	tools: Add zlibutil Third time's the charm... Editing this commit again to resolve merge conflicts. - Bodge Splitting one of Joca’s commits by topic - Bodge Add zlibutil.cpp and zlib to the project's dependencies. - Joca	2024-06-08 15:06:50 +02:00
Joca	6ef1d401bb	lib: Add zlibutil library and test script	2024-05-12 17:24:58 -03:00

BodgeMaster	97b844c6d1	build system: add support for building shaders to SPIRV binaries This adds the following to the project: - glslc from Google’s shaderc - src/shaders directory - shaders are now built as part of the `build` command - forcefully remove some files during the setup process and when cleaning	2024-01-07 20:07:33 +01:00

BodgeMaster	01e5f5eaac	lib/region: Start working on region file parser Something is fishy with dumpnbt or lib/nbt. Attempting to dump the extracted chunk fails, but external tools do manage to parse it.	2023-05-29 14:47:19 +02:00
BodgeMaster	6112da2e6f	lib/game: Start working on game internals Btw: I lost the game.	2023-01-27 03:32:43 +01:00
BodgeMaster	b07d6e2ff6	fossvg (client): Clean up GLFW-related code - add some Vulkan-specific things to deal with GLFW - get rid of useless warnings - allow to set window size from the command line The Window size is fixed for now because that will hopefully make things easier in the strt. I intend to have a resizable window in the future but getting things going is more important.	2023-01-27 01:20:29 +01:00
BodgeMaster	4247bd295a	fossvg (client): Commit to using Vulkan I have decided that we are going to use Vulkan for this. Hopefully, it works out. This commit removes some OpenGL-specific things and adds Vulkan to the build command line.	2023-01-27 01:20:29 +01:00
