2016-01-04pacsort, introduce define for escape_char error codeRikard Falkeborn
The signedness of char is implementation defined. On systems where char is unsigned, comparing a variable of type char with -1 is never true, due to integer promotion rules. To avoid this, introduce a define for invalid field separators where -1 is cast to char. This will ensure that the return value check works for both unsigned and signed char. Fixes one warning [-Wtype-limits] for comparissons with -1 when compiling with -funsigned-char.

2015-10-21pacsort: handle failing list_addRikard Falkeborn
Since it can fail, check the return value. If it fails, we need to free the memory of the object we wanted to add to the list. Signed-off-by: Rikard Falkeborn <rikard.falkeborn@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2014-11-20pacsort: parse inputs up front into control structDave Reisner
This moves most of the parsing work out of the sorting path. The explode and splitfile functions now call input_new and append input_t structs to the list of sort candidates instead of raw strings. This lets us make smarter and easier decisions in the sorting callbacks, which are now also split into the version and file comparison methods for clarity. This fixes two bugs: 1) Incorrect ordering with filenames containing epoch in the pkgver 2) Incorrect ordering with package names which are substrings of each other (e.g. "systemd" and "systemd-sysvcompat"). Performance of the --files mode degrades slightly as a result of this change, but not unreasonably. Sorting with small inputs (5-10) doubles in runtime, but larger inputs (4000+) only increase by 20%. ref: https://bugs.archlinux.org/task/37631 Signed-off-by: Allan McRae <allan@archlinux.org>

2014-01-28Remove ts and sw from vim modeline when noet is setFlorian Pritz
Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand.

2013-09-04Improve --help switch output for pacman utilsJason St. John
Unify the formatting of the --help switch for pacman utils, if it exists. All of the pacman utils will now output help text using the following format: util-name (pacman) v<pacman version> one line description of util's purpose Usage: util-name [options] -b, --bar whatever --bar does -f, --foo whatever --foo does -h, --help display this help message The --help switch does not exist for a couple of the utils, so the help/usage text for those will be displayed when the util is run with no arguments.

2013-01-28pacsort: add -f, --files option for sorting filenamesDave Reisner
Teach pacsort to understand package filenames and optionally strip away some of the context. alpm_pkg_vercmp() intentionally only understands pure versions, so strings such as '18.0-2-x86_64' and '18.0.1-1-x86_64' will be compared wrongly. Partially addresses FS#33455. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2011-12-21include config.h via MakefilesDave Reisner
Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.
