What's Rustpkg?

What's Rustpkg?

Rustpkg is a revamp of Cargo that brings awesome new features such as a build system described in build scripts. It's a purely functional package manager that has no central sources of any kind, but rather installs via URLs. It's similar to how Go's go get tool works, except Rustpkg requires a central metadata file ( in the repository, archive or folder in order to figure out how to build the package. This is a side effect of Rustpkg allowing multiple crates to be defined in a single package (i.e. a package is defined as a set of crates rather than a package being exactly the same as one crate). There's a plan to make it so the is not needed for single-crate packages,

Example of rustpkg for @bjz
#[pkg(id = "",
vers = "0.1.0")];
#[pkg_crate(file = "src/gl.rc")];
use run;
#[pkg_do(build)] // ran before declarative crates (i.e. this will run and then the crate defined above will)
fn build() {
run::run_program(~"lua", ~[~"LoadGen.lua". ~"-style=pointer_rust",
~"-spec=gl", ~"-version=3.3", ~"-profile=core",

Really hacky example of how to compile a CC file using rustpkg. Rustpkg needs heaps of changes before I would even suggest doing anything like this.
// this is a horrible way to do it, but it would work
#[pkg(id = "com.frozencow.some_binding",
vers = "0.1.1")];
#[pkg_crate(file = "src/some_binding.rc")]; // the binding has FFI stuff that links to -lsome_lib
// this would be wrapped by default..
fn cc(path: &Path) {
run::run_program(~"cc", ~[~"-shared", ~"-o", rustpkg::build_dir().push(~"lib").push(~"").to_str(), path.to_str()]);

Haul, a purely functional package manager for Rust



  • Purely functional
    • Different versions of packages can coexist
    • Each package must have a UUID, so packages with conflicting names can coexist
  • Build logic
    • Each package's metadata and build logic is written in a central Rust source file,
    • Dependencies are declared in the package file and will be fetched and installed before
