Raylib 6.2 ported to Zig, with every example checked against C (now running in the browser too)

// stdio FILE handling via opaque pointer
const FILE = anyopaque;
extern fn fopen([*c]const u8, [*c]const u8) ?*FILE;
extern fn fclose(?*FILE) c_int;
extern fn fseek(?*FILE, c_long, c_int) c_int;
extern fn ftell(?*FILE) c_long;
extern fn fread(?*anyopaque, usize, usize, ?*FILE) usize;
extern fn fwrite(?*const anyopaque, usize, usize, ?*FILE) usize;
extern fn fprintf(?*FILE, [*c]const u8, ...) c_int;
extern fn fgets([*c]u8, c_int, ?*FILE) [*c]u8;
extern fn feof(?*FILE) c_int;
extern fn sscanf([*c]const u8, [*c]const u8, ...) c_int;
const SEEK_SET: c_int = 0;
const SEEK_END: c_int = 2;

…directly calling into clib doesn’t look very Ziggy to me

Also tbh, what’s the point. The code is pretty much a straight translation from C to Zig without taking any advantage of Zig’s language features (optionals, error results, allocators, etc etc…), I’m sure Claude could do better…

Also… hrmpf look at all those C string.h and memory.h functions…

            if ((strcmp(&dp.name, ".") != 0) and (strcmp(&dp.name, "..") != 0)) {
                const pathLength = snprintf(&path, MAX_FILEPATH_LENGTH, "%s/%s", basePath, &dp.name);
                if ((pathLength < 0) or (pathLength >= MAX_FILEPATH_LENGTH)) {
                    TraceLog(LOG_WARNING, "FILEIO: Path longer than %d characters (%s...)", @as(c_int, MAX_FILEPATH_LENGTH), basePath);
                } else if (IsPathFile(&path)) {
                    if ((filter == null) or (strstr(filter, FILE_FILTER_TAG_ALL) != null) or (strstr(filter, FILE_FILTER_TAG_FILE_ONLY) != null) or IsFileExtension(&path, filter)) {
                        _ = memcpy(@ptrCast(files.paths[files.count]), @ptrCast(&path), @intCast(pathLength));
                        files.count += 1;
                    }
                } else {
                    if ((filter != null) and ((strstr(filter, FILE_FILTER_TAG_DIR_ONLY) != null) or (strstr(filter, FILE_FILTER_TAG_ALL) != null))) {
                        _ = memcpy(@ptrCast(files.paths[files.count]), @ptrCast(&path), @intCast(pathLength));
                        files.count += 1;
                    }
                    if (scanSubdirs) ScanDirectoryFiles(&path, files, filter, expectedFileCount, scanSubdirs);
                }

This is built for me and my team as a learning exercise for zig

I don’t think you’re doing yourself a favour with this approach. This is C code written with Zig keywords, not Zig code. E.g. you’re kinda missing the forest for the trees and you might just learn bad habits from this codebase.
