v0.5.0

Changes

• cargo-play is now able to accept code from standard input (thanks to @octaltree)
• A new --expand flag to expand macros in your code (thanks to @guswynn)
• --mode flag is no longer constrained to test, check and expand. You can use this flag to override the cargo subcommand cargo-play runs (thanks to @guswynn)
• Updated dependencies

0.4.2

New Flags

• --mode <test|check>, --test and --check are added to control which Cargo subcommand you want to run. With these flags you can run code guarded with cfg(test) or simply check errors with cargo check. (Thanks @rochacbruno)

0.4.1

New Flags

• --quiet and --verbose are added to control Cargo verbosity settings. They will be passed into Cargo unconditionally.

Bugfixes

• base64 encoding is now replaced by base58 to prevent accidental invalid Cargo project name. (Thanks @sunshowers)

0.4.0

New Features

• --infer lets cargo-play to infer the third-party dependencies used in the source code. No more dull dependency specifications. However, with two catches:
  • Under the hood cargo-play finds all the use statements in your code. That means if you directly use some external crates, cargo-play will not be able to recognize such dependency.
  • For the same reason, if you use use statements to rename things, cargo-play would incorrectly recognize these as dependencies.
• --save=<PATH> generates a Cargo project at <PATH> based on the files passed to cargo-play.
• You can now pass flags to your program run by cargo-play. Simply put any flags after -- and these flags will be passed to your program. For example, running cargo play cmd.rs -- --help will be running your program with --help.
• --cargo-options=<OPTIONS> allows you to pass flags to the underlying Cargo command cargo-play invokes.
• --release allows you to run your program in release mode.

Bugfix

• cargo-play is now able to skip shebang and empty lines at the beginning of files correctly. Thanks @norcalli.
• cargo-play is now able to generate Cargo.toml correctly when there is mixed git dependency starting with "d". Thanks @reitermarkus.

v0.3.0

New features:

• Added support for toolchain selecting (+nightly / +beta / +stable, rustup is required).
• Added -c/--clean option to delete built binaries from previous runs.
• Make sure the different order of same set of input files still share the same temporary cargo folder.
