write_mailmap

Use this program and a .mailmap file to apply fixes to your AUTHORS list.

Use a .mailmap file to merge entries in a commit log, for example:

Kevin Burke <kev@inburke.com> Kevin Burke <burke@shyp.com>

If I have commits under both of those email addresses, they'll get merged into one, for the purposes of this program's output.

Install

Find your target operating system (darwin, windows, linux) and desired bin directory, and modify the command below as appropriate:

curl --silent --location --output=/usr/local/bin/write_mailmap https://github.com/kevinburke/write_mailmap/releases/download/0.2/write_mailmap-linux-amd64 && chmod 755 /usr/local/bin/write_mailmap

On Travis, you may want to create $HOME/bin and write to that, since /usr/local/bin isn't writable with their container-based infrastructure.

The latest version is 0.2.

If you have a Go development environment, you can get the binary by running the following:

go get -u github.com/kevinburke/write_mailmap

Usage

write_mailmap > AUTHORS.txt

You can put it in a Makefile like this. Run make authors and the dependencies will automatically download.

WRITE_MAILMAP := $(GOPATH)/bin/write_mailmap

$(WRITE_MAILMAP):
	curl --silent --location --output=$(WRITE_MAILMAP) https://github.com/kevinburke/write_mailmap/releases/download/0.2/write_mailmap-linux-amd64
	chmod 755 $(WRITE_MAILMAP)

force: ;

AUTHORS.txt: force | $(WRITE_MAILMAP)
	$(WRITE_MAILMAP) > AUTHORS.txt

authors: AUTHORS.txt

Then run make authors and you'll get an AUTHORS.txt and your contributors don't have to worry about how to install it.
