subst.mk is a Makefile fragment that implements a general text replacement facility for different classes of files in ${WRKSRC}. For each class of files, a target <class>-subst is created to perform the text replacement. The following variables are used: SUBST_STAGE.<class> "stage" at which we do the text replacement, e.g. pre-configure, post-build, etc. SUBST_MESSAGE.<class> message to display, noting what is being substituted SUBST_FILES.<class> files on which to run the substitution; these are relative to ${WRKSRC} SUBST_SED.<class> sed(1) substitution expression to run on the specified files This basically extracts a useful piece of code from bsd.buildlink2.mk and puts it in a place that allows it to be more widely used, and so that the functionality doesn't depend on USE_BUILDLINK2 being defined.

Usually there's no need to keep the original version of a file "foo" as "foo.subst.sav". Implement SUBST_POSTCMD, which by default cleans up these leftovers. If you need to keep them around, e.g. while debugging, set it to ${DO_NADA}. Remove superfluous whitespace in a comment.

Simplified the code by reducing the number of different targets that are evaluated. Now the SUBST_MESSAGE is only printed once when the substitution is actually done. Before this change it had been printed also when the subst-<class> target had been invoked a second time, but the substitution didn't take place again, which had confused me. Also, converted the code to use ${WARNING_MSG} and ${STEP_MSG}.

${INFO_MSG} "[subst.mk:${_class_}] Nothing changed in $$file."; \
Change instances where we stored `shell command` in a make variable into variables that use the :sh modifier. This still causes expansion to only happen when referenced, and has the advantage of being :Q-safe. Bring back the changes from revision 1.19 of mk/subst.mk now that the problem noted above has been fixed. This passes the buildlink-unwrap regression test.

Reverted the change from 1.29 to 1.30, as it had led to build failures in the "unwrap" class.

Added another diagnostic message to distinguish the cases for non-text file and non-existant file.

Simplified the code by reducing the number of different targets that are evaluated. Now the SUBST_MESSAGE is only printed once when the substitution is actually done. Before this change it had been printed also when the subst-<class> target had been invoked a second time, but the substitution didn't take place again, which had confused me. Also, converted the code to use ${WARNING_MSG} and ${STEP_MSG}.

subst.mk is a Makefile fragment that implements a general text replacement facility for different classes of files in ${WRKSRC}. For each class of files, a target <class>-subst is created to perform the text replacement. The following variables are used: SUBST_STAGE.<class> "stage" at which we do the text replacement, e.g. pre-configure, post-build, etc. SUBST_MESSAGE.<class> message to display, noting what is being substituted SUBST_FILES.<class> files on which to run the substitution; these are relative to ${WRKSRC} SUBST_SED.<class> sed(1) substitution expression to run on the specified files This basically extracts a useful piece of code from bsd.buildlink2.mk and puts it in a place that allows it to be more widely used, and so that the functionality doesn't depend on USE_BUILDLINK2 being defined.
