# $NetBSD: subst.mk,v 1.53 2008/01/26 15:23:21 rillig Exp $
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.

For all those who are interested in the inner workings of pkgsrc, there is a new target "show-all" that fits to the existing "debug", "show-tools", "show-vars" targets. It prints a list of the variables that make up the public interface to pkgsrc. Running this target is especially useful if you want to do some things, you know that they must have been implemented but you don't know what it is called. It also shows the "class" of a variable (user-defined, package-defined, system-defined).

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_IS_TEXT_FILE returns 0 if $${file} is a text file.
_SUBST_IS_TEXT_FILE?= \
Don't rely on file(1) to distinguish text files from binary files. This has proven too unreliable in the past. For example, some Makefile.in files were classified as "Quake I or II world or extension", just because they happen to start with the letters "PACK". This method was also subject to subtle differences in the locale. The new method counts the number of NUL bytes in the file. It does not depend on the locale settings. The -c option of wc(1) counts bytes, not characters, and tr(1), which may interpret multibyte sequences, is protected by LC_ALL. It should also work with the historical implementations of tr(1) that could not handle NUL bytes and discarded them, since this is exactly the intention.

Change instances where we stored `shell command` in a make variable into variables that use the :sh modifier.

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.

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.
