zig-HxA

This is a parser for the HxA file format (by the wonderful Eskil Steenberg in the zig programming language.

This is an alpha project and certain aspects of this implementation could not be testet. Feel free to open an issue or pull request if something catches your eye! Known correct HxA files are also welcome as a test tool!

The Standard

The actual standard can be found in types.hxa. The struct represented there is the actual HxA format.

Usage

const std = @import("std");
const hxa = @import("HxA.zig");

const allocator = std.heap.page_allocator;

const file1 = &try std.fs.cwd().openFile("Test/teapot_v1.hxa", .{ .read = true });
const file2 = &try std.fs.cwd().createFile("Test/teapot_v1_test.hxa", .{ .read = true });
const stdout = &std.io.getStdOut().writer();

// Load HxA file
const teapot_v1 = try hxa.load(allocator, file1);
// Free when done
defer hxa.free(allocator, teapot_v1);

// Print HxA in human readable format to stdout
try hxa.print(teapot_v1, stdout, .data);

// Save HxA to file
try hxa.save(teapot_v1, file2);

Tests

Run all tests with zig build test. Since I am unsure if the parser handles all cases correctly, tests are more of a tool to communicate breaking code change than to validate absolute feature correctness.
