A package composition tool for zig

A package configuration and discovery tool.

Usage

# initializes a zpm instance in the current directory by creating a hidden .zpm folder.
# packages will then be auto-collected and .zpm/pkgs.zig will be created.
zpm init 

# re-runs package autodetection and will regenerate .zpm/pkgs.zig
zpm update

After initialization, ZPM will create the folder .zpm which contains a file .zpm/pkgs.zig. This file contain all collected packages that are available and can be imported into build.zig.

It will look roughly like this:

const std = @import("std");

pub const pkgs = struct {
    pub const android = std.build.Pkg{
        .name = "android",
        .path = .{ .path = "../vendor/AndroidSdk/source/android.zig" },
        .dependencies = &[_]std.build.Pkg{},
    };
};

pub const imports = struct {
    pub const AndroidSdk = @import("../vendor/AndroidSdk/Sdk.zig");
};

Configuration

ZPM will create a zpm.conf file in the .zpm directory that can be used to configure the project instance. This config file is a ini file and has the following entries:

# configures the path where the build.zig import file is generated.
# the path is relative to this file.
pkgs-file = pkgs.zig

Add packages

To add a new package, put a .zpm file anywhere in your project tree next or below the .zpm folder. These files must be ini files where each section declares a package named after the section.

The section allows the following keys:

[zpm]
file = rel/path/to/source.zig # a path relative to this files folder
                              # where the package root is located
deps = args, ini, uri         # comma-separated list of dependencies names
kind = default                # default = a normal runtime package, available under .pkgs
                              # build   = the package will be available under .imports 
                              # combo   = mixed build- and runtime package

These package files don't have to reside next to the package, but can also be declared outside the package source tree. This allows to configure external packages in the .zpm folder for example.

If you change anything in your package declaration files, run zpm update.

This reboot of ZPM is made to be super-simple, but the implementation might be too simple right now. If you feel like something is missing, feel free to fork and PR!
