maven - How to traverse up the directory structure and kick off mvn build in vimscript? -

-

i'm new vim user looking little script allow me call mvn build.

currently map follows

map <f3> :! mvn build<cr>

but because tries build in current working directory (currently java development i'm deep in package under src usually)

how might go directory structure mvn build command works correctly?

thank in advance

the vimscript function finddir() can used find src directory. syntax used in second argument (path) has augmentations basic path specification, 1 of ability specify upward search using ;:

let src_dir = finddir('src', ';')

this find src directory if it's above current directory.

to build in directory, can run

exec '!cd' shellescape(src_dir) '&& mvn build'

i don't think work under windows. in case, think you'd want change directory temporarily using vim's cd command, run command, , change using :cd -.

you can combine commands function

function! runmaveninsrcdir()     let src_dir = finddir('src', ';')     exec 'cd' fnameescape(src_dir)     !mvn build     cd - endfunction

running function have side effect of clobbering vim's previous current directory: in other words, doing :cd - afterwards won't change same directory have before.

you can arrange have function invoked mapping with

map <f3> :call runmaveninsrcdir()<cr>

or command with

command! runmaveninsrcdir call runmaveninsrcdir()

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...
