Configuration Files

All command line options can also be specified in a configuration file. Each option in the configuration file has to start on a new line.

-D i386
-D linux
-I /usr/include

Lines beginning with # are interpreted as comments and will be ignored.

 
-D i386
-D linux
 
-I /usr/include
-I /usr/local/include

Arguments of options containing spaces have to be enclosed in double-quotes. Double-quotes in the argument have to be escaped.

-D __PTRDIFF_TYPE__=int
-D "__SIZE_TYPE__=unsigned int"
-D "__VERSION__=\"4.1.0 (Linux)\""

All occurrences of ${Name} in the configuration file are interpreted as environment variables and replaced by their values, or by nothing if the variable is not defined. To avoid variable replacement, $ has to be escaped.

-I ${LIBDIR}/include
-D OS_STR=\"${OSTYPE}\"
-D OS_VAR=\"\${OSTYPE}\"

The default PUMA configuration file location is /etc/puma.config. It can be overwritten by setting the environment variable PUMA_CONFIG like this:

Use class Puma::Config to load the configuration in the correct order from the command line or a configuration file.
