python - Collaboration of command line and UI widgets -

-

could assume every powerful application provide command line/script input?

even there many many fancy widgets in current software, still think command line input mode in ui still necessary nowadays, since command line/script input more straight forward , neat. if application provide more domain specific script language, more powerful.

is there book provide theory on this? effective ui?

you ask books related theory of this. theory 1 of separating presentation logic business logic, or separation of concerns. goes many names such model/view/controller, model/view/presenter, , many others, , there plenty of books on subject.

if design application way, presentation layer (ie: user interface) separate entity can replaced another. thus, have graphical user interface textual one. arguably, in perfect world apps work way, desktop ui, web ui, command line ui, , on.

this comes @ great cost, however. difficult design applications in way and, because of loose coupling between application , ui there may performance penalties. further add difficulty, inherently difficult provide rich command line interface complex application. how go creating command line input adobe photoshop or microsoft excel, example?

so while it's possible in theoretical sense, practical sense becomes more difficult complexity of ui goes up. there many applications able accomplish this, however. example, many version control systems such bitkeeper, accurev , others have both command line , graphical interfaces.

so, yes, it's possible applications could implement both graphical ui , command line ui, , it's true few of them do, it's not reasonable expect applications or can.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
