Rsoc: Improving Ion's UX, week 1

By AdminXVII

Adding Nix support for Redox (not yet merged)

The libc crate was updated to use all the latest functionalities from Redox OS & Relibc (PR). In the process, a patch was proposed to nix to support Redox OS (PR). This means a whole host of applications that used nix will work out of the box on Redox OS! (A dependency upgrade will still be needed)

Summary of the work done

• Add a return keyword for exiting functions with a code
• When disowning a process, redirect stdout & stderr to /dev/null
• Reduce lock contention on ctrl-c
• Fix a bug where the command expansion wouldn’t reset the default pipes when an expansion error occured. Thanks to aleksator for filing the bug and helping me find the culprit.
• Bring back compilation on Redox by adding Nix (the crate, not the distro) support for redox

The next steps

• Add plugins
• Add user-defined autocompletion
• Improve expansion by reducing allocations
• Adapt more tests from the cracauer test set, and automate them
• Create non-forking function execution
• Explore the possibility for non-forking builtins
