v0.2.8

Changed:

  • Implemented work-around for issue 50. See the section in the README on known issues.

v0.2.7

New:

  • Several environment variables are now given to scripts by cargo-script.

Changed:

  • Overhauled README.md.

Fixed:

  • Warning in the new expr template.

v0.2.6

Fixed:

  • Incompatibility with the version of Cargo shipped with Rust 1.16.0.

v0.2.5

New:

  • Added support for expression script templates.

  • The built-in templates used for scripts can be overridden.

Fixed:

  • Cargo script hanging on build failure on Windows.

v0.2.4

New:

  • Expressions can now use try!/? for propagating errors.

v0.2.3

Fixed:

  • Suspiciously absent 0.2.2 features.

v0.2.2

Fixed:

  • cargo-script no longer gets confused when trying to run scripts with non-identifier characters in their name.

  • Coloured output from cargo now works on *nix.

  • Relative paths in manifests for dependencies are now supported.

v0.2.1

Changed:

  • cargo-script now interrogates cargo to find out where it puts the compiled executables. This should make cargo-script more robust. This only works with Rust 1.17 or higher.

v0.2.0

New:

  • Added --test and --bench flags. These can be used to run a script's tests and benchmarks.

  • Added cargo-script file-association subcommand for managing file associations on Windows.

  • If compiled with the suppress-cargo-output feature, cargo-script will hide output from Cargo if the build takes less than 2 seconds and succeeds.

Changed:

  • cargo-script now requires Rust 1.11 to build.

  • Removed prefix manifests. All other forms are still supported.

  • The cache location on not-Windows when CARGO_HOME is defined is now $CARGO_HOME, rather than $CARGO_HOME/.cargo. Existing data may be migrated to the new location using the --migrate-data option.

Fixed:

  • The result of an --expr invocation now lives longer, allowing borrowed values to be displayed more easily.

  • Fixed issue with expressions containing commas on the command line.

v0.1.5

New:

  • cargo-script now (typically) defaults to using a shared build location. This means that, provided you're using the same compiler, dependencies won't need to be constantly re-built. This can be explicitly controlled by setting the --use-shared-binary-cache option to yes or no.

  • Added --unstable-feature option. This allows you to specify unstable language features that should be enabled.

Changed:

  • The build cache will be retained when the build fails. This means that dependencies don't have to be re-built when the script itself has an error in it.

Fixed:

  • Fixed issue with evaluating an expression containing macros that capture.

v0.1.4

New:

  • Added --features option. This allows you to specify the features that should be enabled.

Fixed:

  • cargo-script should now build with Rust 1.4 stable or higher. Rust 1.3 is incompatible due to the breaking change to the behaviour of str::lines.

v0.1.3

New:

  • run-cargo-script trampoline program for use with hashbangs.

Changed:

  • On UNIX, cargo-script will now try to place its cache in $CARGO_HOME, falling back to $HOME. Behaviour on Windows is unchanged.

  • Various internal fixes and updates.

v0.1.2

New:

  • Added -e and -l as shorthands for --expr and --loop.

  • Added --dep-extern/-D. This introduces a dependency and causes an appropriate #[macro_use] extern crate $name; item to be added. This only applies to expression and loop scripts.

  • Added --extern/-x. This adds a explicit #[macro_use] extern crate $name item. This only applies to expression and loop scripts.

v0.1.1

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.
