cargo-script v0.1.1 Release Notes

  • 🆕 New:

    • 🏁 Not-Windows support, contributed by @Ryman.

    • ➕ Added support for two new embedded manifest formats: short comment manifests and code block manifests. Compared to prefix manifests, these have the advantage of allowing scripts to be valid Rust code, as well as having a measure of self-documentation.

    • You can now pass arguments to scripts. If you want to pass switches, you'll need to add -- after the script name so cargo script knows to stop looking for switches.

    • ➕ Added the --clear-cache flag. This deletes all cached scripts. It can be provided by itself or as part of a regular invocation.

    • ➕ Added the --pkg-path PATH flag. This lets you specify where to create the Cargo package.

    • ➕ Added the --gen-pkg-only flag. This causes cargo script to output a Cargo package, but not attempt to build or run it.

    🔄 Changed:

    • Expressions and loop closures are now wrapped in blocks, rather than an expression. This means you can have multiple statements, link to crates, use things, etc. without having to define a block yourself.

    • Expressions now have their output displayed using the {:?} format specifier. This allows more types to work without extra effort, but does make strings a bit ugly.

    • 🔄 Changed to a not-as-slow argument parser.

    ✂ Removed:

    • ✂ Removed content hashing for scripts. No longer will even minor changes cause Cargo to go back and re-fetch and re-compile all dependencies! Scripts are cached based on a hash of their absolute path, instead. Expressions and loop closures are still cached based on a content hash.
