cscope

问题 I work on C++ projects, and I went through Alex Ott's guide to CEDET and other threads about tags in StackOverflow, but I am still confused about how Emacs interfaces with these different tag systems to facilitate autocompletion, the looking up of definitions, navigation of source code base or the previewing of doc-strings. What is the difference (e.g. in terms of features) between etags , ebrowse , exuberant ctags, cscope, GNU Global and GTags? What do I need to do to use them in Emacs ? Do

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 months ago . I primarily use vim / gvim as an editor and am looking at using a combination of lxr (the Linux Cross Reference) and either cscope or ctags for exploring the kernel source. However, I haven't ever used either cscope or ctags and would like to hear why one might choose one over the other taking into

问题 I'm using cscope for a large project with vim, but without the vim mappings (they froze vim for some weird reason). I'm using cscope commands from within vim, and I want to be able to find uses of structure members throughout the code. Suppose I have something like this: 1 typedef struct _s{ 2 3 int x; 4 } S; 5 6 int main(){ 7 8 int x = 1; 9 10 S my_s; 11 12 my_s.x = 5; 13 14 return my_s.x; 15 } If I issue the command 'cs f s x' it will return both S's member variable and the local main

问题 I have generated ctags for my projects: ctags -f /home/grae/tags --recurse --langmap=C++:.C.h.c.cpp.hpp.inl --languages=C++ --extra=+q --fields=+iaS --c++-kinds=+p --verbose framework/ modules/ /usr/include/ I then added the tags to .vimrc: set tags+=/home/grae/tags I also temporarily added the following (but have now removed): set csto=1 Now when I try Ctrl+] or g] I get the error: cstag: tag not found I shouldn't be using cscope so I'm not sure how this has happened. My current thoughts are

问题 I am using cscope to get familiar with all the keywords used in socket programming. I went to the directory with c files. I used cscope. and then I searched for AF_INET. I got this : #define AF_FILE PF_FILE #define AF_INET PF_INET #define AF_AX25 PF_AX25 This was a full page. I only published part of it. Now I want to know from where this PF_INET is coming? what command I should use. I have seen a guy to double click on PF_INEt and using some command to find it. I don't know what the command

问题 I want to generate Full and Partially Call Trees from cscope database of c and c++ projects in Linux. The project is rather large, so it can be not easy to work with the full call tree of project, so I want to limit call tree generation with grep-like filter of function names. And also I want to be able to build "called by" and "called from" sub-trees from any point. So tool must be interactive and easy to patch. PS: I want use cscope database, because it is already used in project and

问题 I am working on a project which requires the understanding of llvm compiler source-code. To browse source code of llvm, I tried to use cscope with following command in the root directory of the source: cscope -R * But it doesn't work. As there are mainly .cpp and .h files but some .c files are also there. So now I don't have a clue how to make cscope work? Can someone please help? 回答1: You can use following commands to do the required task from the root directory of llvm source tree: touch

问题 When I search for a C symbol or global definition using cscope , it displays the file-names and line numbers. I would like to see the full file-paths so that I can jump to my arch specific file. For example, when searching for global definition of __switch_to on cscope build on Linux code-base, I get: Global definition: __switch_to File Line 0 process.c 297 struct task_struct *__switch_to(struct task_struct *prev, 1 switch_to.h 44 #define __switch_to(prev,next,last) do { \ 2 process.c 202

问题 I want to auto load my cscope.out in the subdirectory of my project, so I add this scripts in my .vimrc , which is as follows: set cscopequickfix=s-,c-,d-,i-,t-,e- if has("cscope") set csprg=/usr/bin/cscope set csto=1 set cst set csverb set cspc=3 "add any database in current dir if filereadable("cscope.out") cs add cscope.out "else search cscope.out elsewhere else let cscope_file=findfile("cscope.out", ".;") "echo cscope_file if !empty(cscope_file) && filereadable(cscope_file) exe "cs add"

问题 When we use cscope to go to definition of a symbol in vim, lots of candidates may be shown in result window. I'd like to perform searching within the window to find what I need quickly. But search function (/) doesn't seem to work in result window, only a few keys are available, j,k,gg,G, etc. Is there anyway to search in cscope result window? Or can anyone share some experiences with how to work more efficiently in such a situation. Thanks. 回答1: You can use the following: " Filter the
