multihash

multihash is the package for creating, serializing and deserializing multihashes. Exposes two structs: Multihash, and UnsignedVarInt.

Examples:

// Bytes for MultiHash
const input = [_]u8{
    0x12, 0x20, 0x41, 0xdd, 0x7b, 0x64, 0x43, 0x54, 0x2e, 0x75, 0x70,
    0x1a, 0xa9, 0x8a, 0x0c, 0x23, 0x59, 0x51, 0xa2, 0x8a, 0x0d, 0x85,
    0x1b, 0x11, 0x56, 0x4d, 0x20, 0x02, 0x2a, 0xb1, 0x1d, 0x25, 0x89,
    0xa8,
};

const result = try Multihash.deserialize(&input, testing.allocator);
defer result.deinit();

pkghash

pkghash is a tool for generating hashes for zig packages. It is forked from the pkghash utility in zap. The main purpose of forking was to add the ability to specify the exact files that would be included in the hash.

usage

Usage: pkghash [options]

Options: 
  -h --help           Print this help and exit.
  -g --git            Use git ls-files
  -f --file <file list>           List Files to include in hash. Directories are included recursively. Does not work with `-g`

Sub-options: 
  --allow-directory : calc hash even if no build.zig is present
                      applies in no-git mode only

Sub-options for --git: 
  --tag=<tag>          : specify git tag to use in template
                         defaults to tag pointing to HEAD
  --template=<file.md> : specify markdown template to render

Example:

pkghash -f LICENSE src/* README.md build.zig build.zig.zon
