Sub Commands

A small single-file based library for common things to do in C:

• implement a “modern” git-like command line
• execute commands and get stdout and stderr from them
• process file paths

License terms

The ISC license is an Open Source license used by the OpenBSD project, allows users to do about whatever they want to with this code.

commandline.h

A single-file C library to implement command line parsing with commands and subcommands, because I failed to find an existing one that I could use without too much dependencies.

Inspiration and thanks from https://libcork.io, which does the job quite fine. If you can depend on an external lib at build-time and run-time, consider using libcork.

filepaths.h

Expose an API to process Unix file paths.

runprogram.h

A single-file C library to implement running subprograms and capturing their output, in a safe way, with multiple pipes: both standard output and standard error are captured. It should be trivial, and it still requires more effort than most would like to put in.

foo.c

A small example program that shows the API from the previous three libs.

pqexpbuffer

This PostgreSQL facility provides a nice wrapper around dynamic allocation of string buffers and is vendored-in here. The PostgreSQL License and the ISC License are compatible, making that possible.
