Restrict checking to exported interface methods

This release publishes work by @MichaelUrman which restricts checking to only exported interface methods as per the philosophy of the tool – ignoring unexported methods which must be by definition defined in the same package.

What's Changed

• Suppress reports from unexported interface methods by @MichaelUrman in #52

New Contributors

• @MichaelUrman made their first contribution in #52

Full Changelog: v2.8.3...v2.9.0

Compile with Go v1.21

Shifting back to Go v1.21 for the benefit of golangci-lint.

Update dependencies, support Go v1.22

What's Changed

Support for Go v1.22.

• deps: upgrade golang.org/x/tools by @rledisez & @tomarrell in #48

Full Changelog: v2.8.1...v2.8.2

Bump dependency version

Bumps golang.org/x/text from 0.3.7 to 0.3.8.

Ignore `errors.Join()` sig by default

The new errors.Join() function was added in Go 1.20, it should be ignored by default.

More info in the Go 1.20 release notes: https://tip.golang.org/doc/go1.20#errors

Check interfaces against ignorePackageGlobs

This release introduces checking of the interface's package against the configured ignorePackageGlobs values.

Previously, only functions called directly from other packages had their packages checked against this option, however this behaviour was unintuitive. This change checks the interface package as well, ignoring interfaces which originate from a package matching a glob pattern.

Closes #34

Update Dependencies

Closes #30, updates x/tools to latest.

Update Dependencies

This release fixes an issue when running wrapcheck over a Go v1.18 codebase due to an older version of a dependency.

Config to ignore interfaces

This release adds the config parameter ignoreInterfaceRegexps, which provides the ability to specify regex patterns which will ignore calls through an interface with a matching name.

For example:

ignoreInterfaceRegexps:
- [dD]ecoder

The above configuration will cause errors returned by methods called on an interface named decoder or Decoder to skip wrapcheck analysis.

Many thanks to @guillaumeio for the contribution!

Improved compilation of `ignoreSigRegexp`

This releases front-loads the compilation of regexps provided via the config file, enabling immediate error reporting.

It also removes the os.Exit(1) upon failing to compile the regexps, to play nicer with golangci-lint.
