statcode is like man but for HTTP status codes. If you're a web developer, you probably spend considerable time looking at response codes (usually errors) and then Googling what they mean. But with statcode, you can simply run $ statcode [status_code] and get a quick explanation of your HTTP response without leaving the terminal.
statcode works on MacOS, Linux, and Windows (if you use Cygwin), with compiled binaries available for every release. You can also install it with pip:
$ pip install statcodeRequires Python 3.0 or higher.
You can install the statcode package from the AUR:
$ aurman -S statcodeThis is a pretty small project (something I put together on a plane ride), but with enough help it could turn into a go-to manual for everything HTTP-related. For example, it should be possible to look up different request headers, e.g. running $ statcode cache-control and getting "Specifies directives for caching mechanisms in both requests and responses." If you'd like to help make this happen, feel free to fork the repo and contribute.
If you've discovered a bug or have a feature request, create an issue and I'll take care of it!
