Gus: The small web server toolkit

Gus is the toolkit for working with the small web in Go.

Think of it as a net/http for small web protocols. You still have to write your server, but you can focus on the logic you want to implement knowing the protocol is already dealt with. It's been said of gemini that you can write your server in a day. Now you can write it in under an hour.

gus/gemini

Gus is determined to be structured as composable building blocks, and the gemini package mainly just defines the structure that holds the blocks together.

The package contains:

• a request type
• a response type
• a "Handler" abstraction
• a "Middleware" abstraction
• some useful Handler wrappers: filtering, falling through a list of handlers
• helpers for building a gemini-suitable TLS config
• a Server that can run your handler(s)

gus/gemtext

The gemtext package today provides a parser for gemtext documents. In the future, there will be conversions for the in-memory parsed representation into markdown, html, and whatever else people come up with.

gus/contrib/*

This is where useful building blocks themselves start to come in. Sub-packages of contrib include Handler and Middleware implementations which accomplish the things your servers actually need to do.

So far there are at least 3 packages:

• log contains a simple request-logging middleware
• fs has handlers that make file servers possible: serve files, build directory listings, etc
• cgi includes handlers which can execute CGI programs
• ...with more to come

Get it

Using gus in your project

To add it to your own go project:

$ go get tildegit.org/tjp/gus

Straight to the code please

=> The code is hosted here on tildegit.

=> The generated documentation is on the go package index.

Contribute

There's lots still to do, and contributions are very welcome!

=> submit an issue or pull request on the tildegit repository,

=> send me an email directly,

or poke me on IRC: I'm @tjp on irc.tilde.chat, and you'll find me in #gemini
