Vim + Ctags + csags build the source insight in linux

Recently, when I write code in linux, I always need to check the definition and call relationship. It is inconvenient to switch to source insight in windows every time, so I tried ctags + cs.pdf. I only want to quickly view the definition of variables and structures and the call relationship of functions. Therefore, it is easy to use. I omit the concept introduction and use it directly: Following the GNU standard, [cpp]. /configure make install three steps simplify the use of ctags and csags installation in two steps: 1. generate the ctags and cssag database files. 2. run the command to search for and index the ctags database file: [cpp] ctags-R. In this case, a ctags file is generated in the current directory where the command is executed, and vim is enabled, view the content and you will understand the principle of ctags to generate the cssag database file: [cpp] cssag-Rbq generates three files in the current directory, cssag. in. out cscope. out cscope. po. for ctags, you only need to remember four shortcuts: tags {ID} to jump to the tag ID: tags display tag stack CTRL-] Jump to the tag under the current cursor (equivalent to S In I ctrl + =) The CTRL-T jumps to an earlier tag in the tag stack (equivalent to ALT + <in SI) for cscope I just need to remember two Commands: c: find the function d that calls this function: Find the function called by this function for ease of use. Add the following code to vimrc: [cpp] nmap <C-\> g: cs find g <C-R> = expand ("<cword>") <CR> nmap <C-\> c: cs find c <C-R> = expand ("<cword>") <CR> in use, press CTRL + \ as the prefix to enter the command mode, press c to view the function that calls this function, and press d to view the function called by this function. In addition, I am a very lazy person, and I don't want to repeatedly comment on bashrc, add command alias, and implementation method: [cpp] alias haha = 'ctags _ cscope_func 'After ctags_cscope_func () {ctags-R cs1_- Rbq} source ~ /. Bashrc can generate the index database file by entering the command haha only once.
