The SUB_FILES and
SUB_LIST variables are useful for dynamic
values in port files, such as the installation
PREFIX in
pkg-message.
The SUB_FILES variable specifies a list
of files to be automatically modified. Each
file in the
SUB_FILES list must have a corresponding
file.in
present in FILESDIR. A modified version
will be created in WRKDIR. Files defined
as a value of USE_RC_SUBR (or the
deprecated USE_RCORDER) are automatically
added to the SUB_FILES. For the files
pkg-message,
pkg-install,
and
pkg-deinstall,
the corresponding Makefile
variable is automatically set to point to the processed
version.
The SUB_LIST variable is a list of
VAR=VALUE pairs. For each pair
%%VAR%% will get replaced with
VALUE in each file listed in
SUB_FILES. Several common pairs are
automatically defined: PREFIX,
LOCALBASE, DATADIR,
DOCSDIR, EXAMPLESDIR,
WWWDIR, and ETCDIR.
Any line beginning with @comment will be
deleted from resulting files after a variable
substitution.
The following example will replace
%%ARCH%% with the system architecture in a
pkg-message:
SUB_FILES= pkg-message
SUB_LIST= ARCH=${ARCH}Note that for this example, the
pkg-message.in file must exist in
FILESDIR.
Example of a good
pkg-message.in:
Now it is time to configure this package. Copy %%PREFIX%%/share/examples/putsy/%%ARCH%%.conf into your home directory as .putsy.conf and edit it.
