# GoSmartKeyboard Environment Variables
## Authentication token file
The authentication token configuration file is set by the environment variable `KEYBOARD_AUTH_TOKEN_FILE`, but defaults to
`XDG_CONFIG_HOME/smartkeyboard/auth-token`.
``` go
--- get authTokenFile from environment
authTokenFile, authTokenFileIsSet := os.LookupEnv("KEYBOARD_AUTH_TOKEN_FILE")
---
```

## Authentication token input (for client)
--- get authTokenInput from environment
authTokenInput, authTokenInputExists := os.LookupEnv("KEYBOARD_AUTH")
---
## HTTP Bind Settings
GoSmartKeyboard supports both standard TCP sockets and unix sockets for the
HTTP server.
First, we check for a unix socket path.
One should prefer a unix socket if their reverse proxy supports it and is on the
same machine.
--- unixSocketPath
unixSocketPath, unixSocketPathExists := os.LookupEnv("KEYBOARD_UNIX_SOCKET_PATH")
---
If the unix socket path is set, we use it. Otherwise, we use the TCP socket.
The TCP socket is configured by the following environment variables:
--- TCPBindAddress
tcpBindAddress, tcpBindAddressExists := os.LookupEnv("KEYBOARD_TCP_BIND_ADDRESS")
---
--- TCPBindPort
tcpBindPort, tcpBindPortExists := os.LookupEnv("KEYBOARD_TCP_BIND_PORT")
