Why use git rm instead of rm'ing files, directories, etc. and then using git add -u? -


i'm having trouble getting git rm delete superfluous directory , it's files project. made me wonder why git rm accepted practice when deleting tracked files instead of rm -rf directory , files outside of git , git add -u stage , prepare deletion of tracked files? latter seems make more sense me dont understand advantages of git rm.

of course, there multiple ways something. advantages using git rm has, are:

  • you control index, not real file system. fact git removes file in file system utility.
  • this means can remove files git without deleting them: git rm --cached.
  • you can precisely remove files want removed, unlike git add -u adds changes index.

especially last 1 important me personally, want full control change add commit. using add -u make me happy (just add .). of course, if happy using add -u, feel free use it.

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
