--

Package unsafe is a program that localises a type from another package allowing the access to unexported fields.

Highlights

• Generates local copy of third-party type and a function to convert to it.
• Optionally adds go:generate comment to allow easy regeneration.

Usage

go run vimagination.zapto.org/unsafe@latest -o OUTPUT.go [-p PACKAGE_NAME] [-x] package.type [packge.type...]

At a minimum, the executable needs to be provided with an output file, via the -o flag, and one or more types to localise.

In addition, you can supply the -x flag to exclude the go:generate header comment, and can provide the -p flag to override the package name.

The following is an example command:

go run vimagination.zapto.org/unsafe@latest -o test/a_test.go -p a_test vimagination.zapto.org/cache.LRU

After the first time, assuming that the -x flag wasn't provided, the go generate command can be used to regenerate and update the output file.
