2012-03-22maint: refactor relpath() from `realpath` for use by `ln`Pádraig Brady
* src/relpath.c: Refactored from realpath.c and adjusted to support returning the relative path rather than just printing to stdout. * src/relpath.h: Export the relpath function. * src/Makefile.am: Reference the refactored relpath module. * po/POTFILES.in: Likewise. * src/realpath.c: Adjust to the refactored relpath module.
2012-03-15realpath: optimize --relative-base usageEric Blake
There is no need to recompute for every path being visited whether the base is a prefix of the relative location. * src/realpath.c (relpath): Hoist base check... (main): ...here. Based on a suggestion by Pádraig Brady.
2012-03-15realpath: let --relative-to default to --relative-baseEric Blake
Most of the time, if someone wants to filter which paths are relative while leaving all others absolute, they also want to to the filtering based on the same --relative-to directory. Make this easier to specify. * src/realpath.c (main): Convert error to default. * doc/coreutils.texi (realpath invocation): Document this. * tests/misc/realpath: Adjust test to match. * NEWS: Document it.
2012-03-15realpath: fix problems with root handlingEric Blake
When --relative-base is /, all other paths should be treated as relative (except for // where it matters). Also, on platforms like Cygwin where / and // are distinct, realpath was incorrectly collapsing // into /. http://debbugs.gnu.org/10472. * src/realpath.c (path_prefix, path_common_prefix): Treat / and // as having no common match. (relpath): Allow for no match even without --relative-base. * NEWS: Document this.
2012-01-25realpath: avoid the use of printfPádraig Brady
This was seen to give an 11% performance improvement. * src/realpath.c (relpath): Avoid using printf. (process_path): Likewise.
2012-01-25realpath: remove extraneous '/' for --relative-to edge casesPádraig Brady
* src/realpath.c (path_common_prefix): Be consistent and always include a leading '/' in the count returned. (relpath): Account for the change in path_common_prefix() and avoid outputting extra '/' chars in relative paths that span the root dir. * tests/misc/realpath: Add the two reported cases.

2012-01-09maint: src/*.c: change remaining quotes (without embedded spaces)Jim Meyering
Run this (twice): git grep -E -l '`[^ ]+'\' src/*.c \ |xargs perl -pi -e 's/`([^ ]+'\'')/'\''$1/'
2012-01-09maint: convert `...' to '...' in --help outputJim Meyering
All affected lines end with \ or \n\, so run this command until it produces no new changes (4 times): git grep -E -l '`[^ ]+'\''.*\\' src \ |xargs perl -pi -e 's/`([^ ]+'\''.*\\)/'\''$1/'
2012-01-07maint: use new emit_try_help in place of equivalent fprintfJim Meyering
Run this command: perl -0777 -pi -e \ 's/fprintf \(stderr, _\("Try `%s --help.*\n.*;/emit_try_help ();/m'\ src/*.c
2012-01-03realpath: a new program to print the resolved pathPádraig Brady
This program is compatible with other realpath(1) implementations, and also incorporates relpath like support, through the --relative options. The relpath support was suggested by Peng Yu, who also provided an initial implemenation of that functionality. * AUTHORS: Add my name. * NEWS: Mention the new command. * README: Likewise. * doc/coreutils.texi (realpath invocation): Add realpath info. * man/Makefile.am (realpath.1): Add dependency. * man/realpath.x: New template. * man/.gitignore: Ignore generated man page. * po/POTFILES.in: Add src/realpath.c. * src/.gitignore: Exclude realpath. * src/Makefile.am (EXTRA_PROGRAMS): Add realpath. * src/realpath.c: New file. * scripts/git-hooks/commit-msg: Add realpath to the list of prefixes. * tests/Makefile.am (TESTS): Add misc/realpath. * tests/misc/realpath: New file.
