# dmd.conf(5)

configuration file for dmd(1)

## NAME

dmd.conf - configuration file for [**dmd**(1)](/dmd/1.md)

## SYNOPSIS

*/etc/dmd.conf*

## DESCRIPTION

dmd will look for the initialization file *dmd.conf* in the following directories:

- 1\.

  The current working directory.

- 2\.

  **$HOME**

- 3\.

  The directory containing the **dmd** executable.

- 4\.

  */etc*

If found, environment variable settings in the file will override any existing settings.

This is handy to make dmd independent of programs with conflicting use of environment variables.

## SYNTAX

Environment variables follow the \[Environment\] section heading, in name=value or name?=value pairs. Comments are lines that start with ;. Variable names are always converted to uppercase, so if you use name=value, actually the variable with name NAME will be written.  If the name?=value syntax is used, the variable with NAME will only be written if it was defined before (in that case the original value is preserved).

## EXAMPLE

; dmd.conf file for dmd

; Names enclosed by %% are searched for in the existing environment

; and inserted. The special name %@P% is replaced with the path

; to this file.

\[Environment\]

DFLAGS="-I%@P%/../src/phobos"
