i started using sass scss stylesheets. these generate *.css files *.scss files. question is, files check version control? right check in both main.scss , generated main.css . wonder though if there way check in *.scss file , ensure *.css files generated on deployment. in general, don't need check generated files source control. long code generation works consistently, , use consistently update target .css files, don't think need put them in source control. that said, suggestion not put generated files source control intended more binary files (i.e. libs or executables generated build). main reason binary files cannot diffed/merged, if multiple people try checkin changes same binary, may end merging issues cannot resolved. since you're dealing plain text css files, don't think it's big of deal put them in source control too, have backup of actual target file.

is there function accomplish equivalent of array_search $needle array? like, ideal solution: $needle = array('first', 'second'); $haystack = array('fifth','second','third', 'first'); // returns key 1 in haystack $search = array_search( $needle, $haystack ); if no function, other functions accept needles may arrays can use create custom function? this might build function: $intersection = array_intersect($needle, $haystack); if ($intersection) // $haystack has @ least 1 of $needle if (count($intersection) == count($needle)) // $haystack has every needle

(if arg20-ish (setf temp (acons 'arg20-ish arg20-ish temp))) (do-something-with temp)) which not seem elegant, messy many arguments , when these need changed. i looking smarter way this , both sake of writing particular function , learning how think in lisp and/or functional programming. the tricky part me figuring out how names of arguments or symbol use, without hand coding each case. if &rest provided arg names easy filter out nils loop or mapcar, since doesn't, can't see how "automate" this. i'm totally interested in other solutions 1 described, if people think way unnatural. edit : below example of trying do: an object created, non-fixed number of dat...
