makeppclean [ -b ] [ -l ] [ -R ] [ -r ] [ -v ] [ path ... ]
mppc [ -b ] [ -l ] [ -R ] [ -r ] [ -v ] [ path ... ]
Makeppclean efficiently removes files that were knowingly generated
through makepp. For each path, if path is not a directory and was
known to be generated by makepp by virtue of having a build info file
with a matching signature, then remove path and its build info file;
and if path is a directory, do the same for every file in path, and
then remove the build info directory below path. path defaults to ".".
The traditional approach to removing generated files is to create a
"clean" target in your makefiles whose action is to remove all of the
targets. This approach has some fundamental limitations:
* It requires that all the relevant makefiles be loaded before
cleaning. This can take quite a while.
* If the clean target in one makefile depends on the clean target in
another makefile, then it is possible that a file that must be built
in order to load one of the makefiles (e.g. because of a prebuild
statement) has already been built and cleaned by the time it needs to
be built again. Makepp wisely fails in this situation, rather than
potentially building the same file many times during the course of a
single build.
Provided that your intention is to remove all the generated files
without regard for which makefile (if any) currently generates them,
then these limitations are avoided by using makeppclean.
OPTIONS
-A filename
--args-file=filename
--arguments-file=filename
Read the file and parse it as possibly quoted whitespace- and/or
newline-separated options.
-b
--build-cache-links
--only-build-cache-links
Remove only links or files from a build cache.
-d
--empty-directories
Remove directories that became empty after removing their content.
Since directories are not usually created by rules, makepp does not
keep track of which one it created. Therefore this applies to
those, where makepp created something, whether the directory was
created manually or automatically.
-?
-h
--help
Print out a brief summary of the options.
-k
--keep-src-info
--leave-src-info
Leave the build info directory below each named directory.
-l
--log
--only-logs
Remove only the raw logfiles, which can be many in case of
traditional recursion.
-m
--meta
--only-meta
--makepp
Remove only the meta information subdirectories.
-R
--repository-links
--only-repository-links
Remove only links pointing to a repository.
-r
--recurse
--recursive
Descend each named directory recursively. Symbolic links are not
followed.
-v
--verbose
Enable verbose output to STDERR.
-V
--version
Print out the version number.
ENVIRONMENT
Makeppclean looks at the following environment variable:
$MAKEPPCLEANFLAGS
Any flags in this environment variable are interpreted as command
line options before any explicit options. Quotes are interpreted
like in makefiles.
