This tool merges require blocks in go.mod files since go mod tidy doesn't do it. It also separates the direct and indirect dependencies and sorts them alphabetically.

Before	After

go install github.com/abhijit-hota/modfmt@latest

The binary outputs the formatted go.mod to standard output.

Alternatively, you can use the --in-place flag to replace the contents of the go.mod file in place.

In your Go project root, run:

modfmt --in-place

I hacked this tool together using the official parser in less than 2 hours and unsurprisingly there are a few drawbacks with this:

• require blocks come last after using this. Can be fixed with little effort I think?
• Comments in require blocks are not preserved.
