# Gophor
|
|
|
|
|
|
|
|
|
|
A Gopher server written in GoLang as a means of learning about the Gopher
|
|
|
|
|
protocol, and more GoLang.
|
|
|
|
|
|
|
|
|
|
Possibly beta quality soon? More likely alpha right now.

# Features
|
|
|
|
|
|
|
|
|
|
- ZERO external dependencies
|
|
|
|
|
|
|
|
|
|
- Item type characters beyond RFC 1436 standard (see below)
|
|
|
|
|
|
|
|
|
|
- Security focused -- `Until we reach beta/stable, maybe don't trust this...`
|
|
|
|
|
|
|
|
|
|
- File caching -- Until LRU is implemented, this means cache size is infinite,
|
|
|
|
|
which for a gopher server of very limited size, this is fine. Probably.
|
|
|
|
|
|
|
|
|
|
- Separate system and access logging with output to file if requested (or
|
|
|
|
|
disable both!)
