cmd/

What is going on here?

TL;DR

• cmd/maincmd package exposes all of this app's command line functionality in a Main()

• cmd/go-httpbin and cmd/go_httpbin build identical binaries using the maincmd package for backwards compatibility reasons explained below

Why tho

Originally, this project exposed only one command:

cmd/go-httpbin/main.go

But the dash in that path was incompatible with Google App Engine's naming restrictions, so in moving httpbingo.org onto Google App Engine, that path was (carelessly) renamed to

cmd/go_httpbin/main.go

That change had a number of unintended consequences:

• It broke existing workflows built around go get github.com/mccutchen/go-httpbin/cmd/go-httpbin, as suggested in the README

• It broke the Makefile, which was still looking for cmd/go-httpbin

• It broke the absolute aesthetic truth that CLI binaries should use dashes instead of underscores for word separators

So, to restore the former behavior while maintaining support for deploying to App Engine, the actual main functionality was extracted into the cmd/maincmd package here and shared between the other two.

(This is pretty dumb, I know, but it seems to work.)
