2012-04-24scripts/library: introduce parseoptsDave Reisner2-0/+161
This will replace our current options parser used in pacman-key, makepkg, and ideally elsewhere. It follows heuristics closer to that of GNU getopt long (and thus pacman itself), with the exception that it does not allow for options with optional arguments. Due to the way this parser will be used, this sort of functionality will not be needed. Instead of relying on eval+set, options are normalized into an array, OPTRET, which callers should expect to be populated after returning from parseopts. This avoids problems with quotes and spaces in arguments, assuming that the user quotes properly when passing into the application. A new test harness for parseopts is added in test/scripts.

2012-04-07Revert "parseopts: normalize options into an array"Dave Reisner1-11/+21
This was really only half a fix for FS#28445, as it still doesn't correctly handle the case of filenames with spaces. In the short term, there is no obvious fix for this. In the long term, I believe the correct decision is to rewrite the options parser to be more in line with GNU getopt_long. This reverts commits: ca4142714137b16feabac09c4cda86b0a75036f8. 969dcddbdf9d5dbd91aa414cdd193f3fb26b644b.
2012-04-07parse_options: initialize unused_options as arrayDave Reisner1-1/+1
Since we treat this as an array, we need to initialize it as one. This avoids addition of an empty element to the option string when we set the option array from the calling program, e.g. +/usr/bin/makepkg[2033]: set -- -i --pkg vim -- '' Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-02-17parseopts: normalize options into an arrayDave Reisner1-21/+11
Modify parse_options logic to fill an array instead of printing parsed options. Avoid eval like the plague. Because it is the plague. Fixes bugs such as FS#28445. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05parse_options: accept multiple argumentsAllan McRae1-7/+23
Allow command-line options to accept multiple arguments without additional quoting by taking the list of arguments until one starting with a "-" is reached. The only current use of this is the --pkg option in makepkg. This allows (e.g.) makepkg --pkg foo bar and packages "foo" and "bar" will be built.

2011-07-05parse_options: implement optional argumentsAllan McRae1-4/+15
This allows options specified with a trailing "::" to optionally take arguments. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-15parse_options: adjust error messagesAllan McRae1-3/+3
Provide consistent error messages for unknown long and short options. Also get full string translation for the messages. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-15scripts/library: add README fileAllan McRae1-0/+15
Add a README file to briefly document the code snippets in the scripts library folder. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-15scripts: refactor output formatting functionsAllan McRae1-0/+21
Move the common output formatting functions into a separate library file and import that into each script. makepkg is excluded due to its additional color formatting. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-15makepkg: move option parsing code to separate fileAllan McRae1-0/+87
This move the getopt replacement function parse_options out of makepkg.sh.in and into a separate file. The code is inserted into the relevant place in makepkg using m4. This will allow the reuse of the option parsing code in other scripts (i.e. pacman-key) while avoiding code duplication.
