# dcd-server(1)

autocompletion server for the D programming language

## NAME

dcd-server - autocompletion server for the D programming language

## SYNOPSIS

**dcd-server** \[**-I** *directory*\] \[**-p\|--port** *portNumber*\] \[**--tcp**\] \[**--socketFile** *filePath*\] \[**--logLevel** *level*\] \[**-h\|--help**\] \[**--version**\]

## DESCRIPTION

**dcd-server** caches information about D source files that were found

## OPTIONS

- **-p, --port** *portNumber*

  Choose the port number on which **dcd-server** listens. This switch implies --tcp.

- **--tcp**

  Listen on a TCP socket instead of a UNIX domain socket. This is the default on Windows.

- **--socketFile** *filePath*

  Set the path to use for the UNIX domain socket. Has no effect if the --tcp or --port switches are used.

- **--logLevel** *level*

  Configure the logging level for dcd-server. Valid values are *all* *trace* *info* *warning* *error* *critical* *fatal* *off*

- **-I** *directory*

  Includes *directory* in the list of directories to scan for source files. This option can be specified multiple times.

- **-h, --help**

  Prints a help message.

- **--version**

  Prints the current version number and exits.

## FILES

**dcd-server** can be configured through the use of a file called *dcd.conf* This file should be placed in one of the following locations:

- •

  */etc/dcd.conf*

- •

  *${XDG\_CONFIG\_HOME}/dcd/dcd.conf*

- •

  *${HOME}/.config/dcd/dcd.conf*

  Each line in the file should be a path to search for D source files. A line in *dcd.conf* is equivalent to passing that same line to **dcd-server** with the *-I* option. Lines that start with the '#' character are ignored.

  Unless the --tcp switch is used, **dcd-server** will default to communicating with the client over a UNIX domain socket. **dcd-server** will attempt to create the socket in the following locations:

- •

  *${XDG\_RUNTIME\_DIR}/dcd.socket*

- •

  */tmp/dcd-${UID}.socket*
