A program for running other programs
ir takes a JSON specification of processes to run, and runs
them. The JSON specification gives detailed control over all aspects of the
process:
- the executable to run
- the command line
- the environment
- stdin [planned], stdout, stderr, and additional file descriptors
- current working directory [planned]
- umask [planned]
- signal disposition [planned]
- process group [planned]
ir runs the processes in concurrent subprocesses, collects detailed results,
and returns them in a JSON document. Results include,
- process ID
- exit status
- resource usage
- file descriptor outputs, if requested
ir is a project to help me learn Rust. I deliberately avoid many dependency
crates (other than the excellend Serde), to get experience with Rust systems
programming.
Integration tests are written in Python and run under pytest, because this is
easy to do.
