Create http server listening on unix sockets or systemd socket activated fds
## Quick Usage
Just replace `http.ListenAndServe` with `anyhttp.ListenAndServe`.
```diff
- http.ListenAndServe(addr, h)
+ anyhttp.ListenAndServe(addr, h)
```
## Address Syntax
### Unix socket
Syntax
unix/<path to socket>
Examples
unix/relative/path.sock
unix//var/run/app/absolutepath.sock
### Systemd Socket activated fd:
Syntax
sysd/fdidx/<fd index starting at 0>
sysd/fdname/<fd name set using FileDescriptorName socket setting >
Examples:
# First (or only) socket fd passed to app
sysd/fdidx/0
# Socket with FileDescriptorName
sysd/fdname/myapp
# Using default name
sysd/fdname/myapp.socket
### TCP port
If the address is a number less than 65536, it is assumed as a port and passed as `http.ListenAndServe(":<port>",...)`
Anything else is directly passed to `http.ListenAndServe` as well. Below examples should work
:http
:8888
127.0.0.1:8080
