goptimizer

goptimizer

Optimizes go code using betteralign.

This is a wrapper around the betteralign and go tooling. This will copy all files under the current go.mod file to a temporary directory, go vendor all the code, run betteralign on them on all packages and then use go to build the binary. The binary is then copied back to the original directory.

You must not have a binary in the current directory or nothing will be done.

You may pass flags to the go tool, however punctuation is slightly different.

Installation

go install github.com/dkorunic/betteralign/cmd/betteralign@latest
go install github.com/johnsiilver/goptimizer@latest

Running notes

This will ignore any package that imports reflect, as we have found it does not reliably work for those packages. It will ignore generated files, though there is a flag that will allow this.

There is also a flag to make sure that tests are working. This will run go test on the code.

This program is quite slow, so it should only be done as an optimization step before a release.

Usage

Simply run goptimizer in the directory of your go main file. This only works with go modules.

goptimizer [flags]

I like to run it like this:

go test ./...
[Make sure that works]
goptimizer --goflags="--ldflags=-s -w" --runTests

This makes sure that all tests work after being aligned before it builds the final binary.
