Coverage instrumentation program created for lightning talk at GopherCon 2024: github.com/cixel/gc2024
This is just a learning tool and should not be used seriously. If you need code coverage, please use the coverage tool built into Go.
$ go install ehden.net/cover@latest
$ go build -toolexec cover
The COVER_PATHS environment variable can contain a comma-separated list of packages which should be instrumented.
If missing or empty, only the main package is instrumented.
If COVER_PATHS=*, all packages in the build will be instrumented.
This is rather expensive and isn't recommended, but could be fun.
