ziex/flake.nix

# This flake does not package ziex.
# It allows nix users to `nix run github:ziex-dev/ziex` which builds
# and runs the `zx` binary. The build is not done inside a sandbox.
#
# This allows you to bootstrap a ziex project and then use whatever
# zig dev environment you are comfortable with.
