homerc (see section 7.3.1 Program Description Attributes). The initialization values
are identified by the long option name followed by white space and any
associated value. The value, if any, will continue through the end of
the last line not continued with a backslash. Leading and trailing
white space is stripped.
Initialization files are selected both by the homerc entries and,
optionally, via an automatically supplied command line option. The
first component of the homerc entry may be an environment
variable such as $HOME, or it may also be $$ (two
dollar sign characters) to specify the directory of the executable.
For example:
homerc = "$$/../share/autogen"; |
will cause the AutoOpts library to look in the normal autogen datadir for an initialization file.
The initialization files are processed in the order they are specified
by the homerc attribute, so that each new file will normally
override the settings of the previous files. A few options may be
marked for immediate action (see section 7.3.4.4 Immediate Action Attributes). Any such
options are acted upon in reverse order. The disabled
load-opts (--no-load-opts) option, for example, is an
immediate action option. Its presence in the last homerc file
will prevent the processing of any prior homerc files.
Further initialization file processing can be suppressed by
specifying --no-load-opts on the command line, or
PROGRAM_LOAD_OPTS=no in the environment, or no-load-opts
in any of the specified homerc files.
