v0.3.0

This release adds support to the CLI for using Go package patterns like ./...
to match and transform files.
You can now use errtrace -w ./... to instrument all files in a Go module,
or errtrace -l ./... to list all files that would be changed.

Added

• cmd/errtrace: Support Go package patterns in addition to file paths.
  Use errtrace -w ./... to transform all files under the current package
  and its descendants.

Changed

• cmd/errtrace:
  Print a message when reading from stdin because no arguments were given.
  Use '-' as the file name to read from stdin without a warning.

v0.2.0: CLI improvements

This release contains minor improvements to the errtrace code transformer
allowing it to fit more use cases.

Added

• cmd/errtrace: Add -l flag to print files that would be changed without changing them. You can use this to build a check to verify that your code is instrumented.

• cmd/errtrace: Support opt-out on lines with a //errtrace:skip comment. Optionally, a reason may be specified alongside the comment. The command will print a warning for any unused //errtrace:skip comments.

  if err != nil {
    return io.EOF //errtrace:skip(io.Reader expects io.EOF)
  }

v0.1.1

This release contains minor fix-ups to better consume the project.
Install this with:

go get braces.dev/errtrace@v0.1.1

See the prior release announcement for additional information.

Changed

• Lower go directive in go.mod to 1.20 to allow use with older versions.

Fixed

• Add a README.md to render alongside the API reference.

v0.1.0: Introducing errtrace

Introducing errtrace, an experimental library that provides better stack traces for your errors.

Install the library with:

go get braces.dev/errtrace@v0.1.0

We've also included a tool that will automatically instrument your code with errtrace.
In your project, run:

go install braces.dev/errtrace/cmd/errtrace@v0.1.0
git ls-files -- '*.go' | xargs errtrace -w

See README for more information.
