Safe Unix shell-like parameter expansion/variable substitution via cross-platform CLI or Rust API

Safe Unix shell-like parameter expansion/variable substitution for those who need a more powerful alternative to envsubst but don't want to resort to using Bash's eval, while also not wanting to use a full-on templating engine. Xpanda is available as a native single-binary Windows/Linux CLI tool and a Rust library.

See how it compares to other programs.

$ cargo build

Test

Linting

This project uses rustfmt for formatting and clippy for linting. Run them with:

$ cargo fmt 
$ cargo clippy

Unit/Integration/Doc Testing

All code that goes into master must pass all tests. To run all tests, use:

$ cargo test

Benchmarking

Benchmarks can be ran using:

$ cargo bench

Fuzz Testing

And fuzz testing, located in the xpanda-fuzz directory, can be ran using the cargo-fuzz tool, which has to be installed first:

$ cargo install cargo-fuzz 

It must then be ran using the nightly channel:

$ cargo +nightly fuzz run fuzz_input --fuzz-dir xpanda-fuzz
