Write scripts that call subprocesses with the ease of shell scripting and the power of Dart.

1.0.0 #

  • Stable release.

  • Expose the args() function, which shell-escapes multiple arguments at once.

  • Update internal type annotations for compatibility with dart-lang/sdk#52801.

0.3.2 #

  • Declare support for Dart 3.

0.3.1 #

  • Add Script.outputBytes, which works like Script.output but returns the raw bytes instead of a string representation.

0.3.0 #

  • Add Script.kill() to send a ProcessSignal such as SIGKILL or SIGTERM to terminate a script or stream. Defaults to SIGTERM. Capturing functions like Script.capture or silenceUntilFailure can't terminate their callbacks but the ProcessSignal can be reacted to via their new onSignal handler.

0.2.7 #

  • Ensure that Scripts always cancel streams piped to their stdin sinks after exiting. This prevents rare cases where programs could deadlock waiting for events to be processed.

0.2.6 #

  • Add a stderrOnly parameter to BufferedScript.capture() and silenceUntilFailure(). If this parameter is true, only the stderr from the callbacks will be buffered or silenced, and the stdout will be emitted normally.

0.2.5 #

  • Add LineStreamExtensions.withSpans(), which adds SourceSpanWithContexts to a stream's lines for better error messaging and debugging.

  • Add readWithSpans(), which adds SourceSpanWithContexts to a file's lines for better error messaging and debugging.

  • Add LineAndSpanStreamExtensions, which provides various extension methods that preserve source spans.

0.2.4 #

  • Add a silenceUntilFailure() function that suppresses output for a block of code until it emits an error.

0.2.3+2 #

  • Documentation improvements only.

0.2.3+1 #

  • Properly respect onlyMatching in the top-level grep() method.

0.2.3 #

  • Add an onlyMatching flag to grep() which prints the sections of input lines that match the given regular expression.

  • Add a teeToStderr transformer and extension method on Stream<List<String>>. This passes a stream to stderr without modifying it, which is useful for debugging.

  • Add a Script.mapLines constructor that returns a script that maps stdin lines according to a String Function(String).

  • Add support for passing a String Function(String) to Script.pipeline and Script.operator | to map stdin lines.

  • Fold stack frames for a few more packages used internally.

0.2.2 #

  • Add a BufferedScript class that buffers output from a Script until it's explicitly released, making it easier to run multiple script in parallel without having their outputs collide with one another.

  • If the same capture() block both calls print() and writes to currentStdout, ensure that the order of prints is preserved.

  • If the same capture() block writes to both currentStdout and currentStderr, ensure that the relative order of those writes is preserved when collected with combineOutput().

0.2.1 #

  • Give the stream transformers exposed by this package human-readable toString()s.

0.2.0 #

  • Add a debug option to wrapMain() to print extra diagnostic information.

  • Add a runInShell argument for subprocesses.

  • Accept Iterable<String> instead of List<String> for subprocess arguments.

  • Use 257 rather than 256 as the sentinel value for ScriptExceptions caused by Dart exceptions.

  • Fix a bug where Dart exceptions could cause the script to exit before their debug information was printed to stderr.

0.1.0 #

  • Initial release.
