Specifying a commit in go.mod instead of a local replace for development

Sometimes you are making changes to a dependency in another of your go projects and instead of adding a replace command in the go.mod file you want to update that entry in go.mod to point to a specific commit in the repo.

To do so, all that you need to do is:

1. Get the git commit that you want included in your build
2. Change directories to the same directory that your project’s go.mod file resides in which you want to refer to the library with the specific commit
3. Run the following command which will automatically update your go.mod file with the correct “version” for your dependency go get github.com/rchapin/rlog@<commit-hash>
