shellexpand, a library for shell-like expansion in strings

Documentation

shellexpand is a small dependency-less library which allows one to perform shell-like expansions in strings, that is, to expand variables like $A or ${B} into their values inside some context and to expand ~ in the beginning of a string into the home directory (again, inside some context).

This crate provides generic functions which accept arbitrary contexts as well as default, system-based functions which perform expansions using the system-wide context (represented by functions from std::env module).

Usage

Just add a dependency in your Cargo.toml:

[dependencies]
shellexpand = "1.0"

See the crate documentation (a link is present in the beginning of this readme) for more information and examples.
