emacs - Hierarchical GTAGS TAG file -

-

one liner: looking "hierarchical" tags file setup whereas if global cannot find tagsdb in gtagsdbpath directory climbs dir chain till finds another.

long liners:

i have project file structure

/vob/project-name/src/ ==> root of project src directory

under directory there subdirs like: ./utils, ./common, ./iplib, ./ipv6lib, ./subsystem1, ./subsystem2 etc

i work on subsystem1

the big tags file huge.

i have..

setenv  gtagsroot /vobs/project-name/src setenv  gtagsdbpath /vobs/project-name/src

these take 40mins build.

i have tags file in ./subsystem1/sre

currently have 2 shell files:

toptags :

setenv  gtagsroot /vobs/project-name/src setenv  gtagsdbpath /vobs/project-name/src

bottomtags:

setenv  gtagsroot /vobs/project-name/src/subsystem1/src setenv  gtagsdbpath /vobs/project-name/src/subsystem1/src

in way, can build top project file , bottomtags every , there churn is.

also, currently, when (setq ggtags-update-on-save nil) each time write file 3 processes spawned off not die. got stern e-mail sysadmin keeping 150 processes standing.

locate-dominating-file need.

(locate-dominating-file default-directory gtags-file-name)

will give name of closest enclosing directory containing file called gtags-file-name, or nil if there no such directory.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

-
i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
