run-by-arch 0.0.1

Run different shell commands depending on your OS or CPU arch.

run-by-arch helps you organize and run programs compiled for varying operating systems and CPU target architectures.

Installation

run-by-arch is a Python program that works with both Python 2 and 3. You can install it with pip install run-by-arch.

run-by-arch does not depend on any other Python packages, so it is safe to install it into your system Python.

Why do I need run-by-arch?

For example, if you are working on a program called my-program with binaries stored on a Network File System instance shared between 64-bit Linux and MacOS users, then users of both operating systems can run run-by-arch my-program followed by the arguments for that program.

For a Linux user, run-by-arch will run the binary found at the directory ./run-by-arch/linux-x86_64/my-program.

For a MacOS user, run-by-arch will run the binary found at ./run-by-arch/darwin-x86_64/my-program.

If you set the environment variable RUN_BY_ARCH_PREFIX, you can tell run-by-arch to look anywhere else on your filesystem.

run-by-arch expects the path at RUN_BY_ARCH_PREFIX to have subdirectories named after the operating system hyphenated with the CPU architecture. If you set RUN_BY_ARCH_PREFIX=/prefix, then your binaries should be located at:

• /prefix/darwin-x86_64/ for 64-bit MacOS computers with Intel CPUs (not the Apple M1)

• /prefix/linux-x86_64/ for 64-bit Linux computers

• /prefix/windows-x86_64/ for 64-bit Windows computers

• /prefix/linux-i386/ for 32-bit Linux computers

• …and so on…
