Programs may be “pre-configured” before normal command line options are processed (See see section Immediate Action Attributes). How configuration files and environment variables are handled get specified with these attributes.
Indicates that the command line usage of --load-opts
and/or
--save-opts
are disallowed.
Indicates looking in the environment for values of variables named,
PROGRAM_OPTNAME
or PROGRAM
, where PROGRAM
is the
upper cased C-name
of the program and OPTNAME
is the
upper cased C-name
of a specific option. The contents of
the PROGRAM
variable, if found, are tokenized and processed.
The contents of PROGRAM_OPTNAME
environment variables are taken
as the option argument to the option nameed optname
.
Specifies either a directory or a file using a specific path, a path based
on an environment variable or a path relative to installation directories.
The method used depends on the first two characters of the name. If the
first character is not the dollar character ($
), then it is
presumed to be a path name based on the current directory.
Otherwise, the method depends on the second character:
The path is relative to the directory where the executable was found.
The path is relative to the package data directory, e.g.
/usr/local/share/autogen
.
The path is derived from the named environment variable.
Use as many as you like. The presence of this attribute
activates the --save-opts
and --load-opts
options.
See the optionMakePath(3AGEN)
man page for excruciating details.
See section configuration file presets.
Specifies the configuration file name. This is only useful if you
have provided at least one homerc
attribute.
default: .<prog-name>rc
