To achieve similar sourceinsight functionality, the Vim+ctags+cscope+taglist+source Explore +nerd tree is implemented.

One, install the plug-in

1) Install Ctags and Cscope

Ubuntu can be installed directly from the command:

sudo Install ctags cscope

Note: Cscope and ctags function similar, but can supplement ctags insufficiency, both can combine Ctags convenience, double can use cscope supplement ctags limitation, is a powerful tool of Linux kernel code analysis.

2) Install TagList:

By adding to the. VIMRC:

' Taglist.vim '
Bundle "Scrooloose/nerdtree"
Bundle "WESLEYCHE/SRCEXPL"
Bundle "Majutsushi/tagbar"

Re-execute: Bundleinstall command can be installed automatically.

3)

Second, configure and use plug-ins

The Linux kernel has a generated script for the tag database with Ctags and Cscope, and the corresponding database file can be generated in the kernel source code directory by command:

 Make Ctags  make Cscope

Note: The former generates a 92M tags file, which generates Cscope.files (the directory of Analysis files) and other file databases.

Configure the Ctags and Cscope databases with VIM linkage:

"""ctags Database Path"""""""Set Tags=/home/magc/workspace/linux-2.6.32.67/Tags"""cscope Database Path"""""""Set CSPRG=/usr/bin/cscope"Whereis cscopeSet csto=0            "cscope DB Search FirstSet CST"cscope db Tag db searchSet Nocsverb"verbose off"CS DB PathCS add/home/magc/workspace/linux-2.6.32.67/cscope.out/home/magc/workspace/linux-2.6.32.67Set Csverb"Verbos off
