cscope 过滤目录介绍

第一步创建自己的cscope脚本~/.local/bin/cscope.sh，如下：

function my_cscope(){CODE_PATH=`pwd`echo "$CODE_PATH"echo "start cscope...."if [ ! -f "$CODE_PATH/cscope.files" ];thenecho "cscope.files not exist!"elserm -f $CODE_PATH/cscope.*fiif [ ! -d "$CODE_PATH/rt-thread" ];thenfind . \( -path './arch/arc' \-o -path './arch/alpha' \-o -path "./arch/blackfin" \-o -path "./arch/cris" \-o -path "./arch/h8300" \-o -path "./arch/ia64" \-o -path "./arch/m68k" \-o -path "./arch/microblaze" \-o -path "./arch/mn10300" \-o -path "./arch/openrisc" \-o -path "./arch/powerpc" \-o -path "./arch/score" \-o -path "./arch/sparc" \-o -path "./arch/um" \-o -path "./arch/x86" \-o -path "./arch/c6x" \-o -path "./arch/m32r" \-o -path "./arch/microblaze" \-o -path "./arch/nios2" \-o -path "./arch/powerpc" \-o -path "./arch/sh" \-o -path "./arch/um" \-o -path "./arch/xtensa" \-o -path "./arch/cris" \-o -path "./arch/hexagon" \-o -path "./arch/mips" \-o -path "./arch/openrisc" \-o -path "./arch/s390" \-o -path "./arch/sparc" \-o -path "./arch/unicore32" \-o -path "./arch/parisc" \-o -path "./arch/tile" \-o -path "./arch/tile" \-o -path './arch/c6x' \) \-prune -o -name "*.[chxsS]" -print > cscope.fileselsefind . \( -path "./rtos/rt-thread/rt-thread/bsp/mb9*" \-o -path "./rtos/rt-thread/rt-thread/bsp/at91*" \-o -path "./rtos/rt-thread/rt-thread/bsp/ess*" \-o -path "./rtos/rt-thread/rt-thread/bsp/gd3*" \-o -path "./rtos/rt-thread/rt-thread/bsp/lpc*" \-o -path "./rtos/rt-thread/rt-thread/bsp/ls*" \-o -path "./rtos/rt-thread/rt-thread/bsp/mi*" \-o -path "./rtos/rt-thread/rt-thread/bsp/imx*" \-o -path "./rtos/rt-thread/rt-thread/bsp/rasp*" \-o -path "./rtos/rt-thread/packages/packages/iot/*" \-o -path "./rtos/rt-thread/rt-thread/bsp/stm32/stm32f*" \-o -path "./bootrom" \-o -path "./u-boot" \-o -path "./tools" \) \-prune -name "*.cc" -o -name "*.[chxsS]" \-print > cscope.filesfiecho "cscope -Rbkq -i cscope.files"cscope -Rbkq -i $PWD/cscope.files > cscope.log 2>&1echo "cscope finished"}my_cscope;

我的这个脚本首先去区分当前执行cscope命令的目录是rt-thread目录还是linux 目录，因为不同的代码要过滤过目录不一样。 此外，还会通过 重定向 将cscope在解析文件cscope.files过程中输出的log重定向到 cscope.log 方便问题问题。关于 find 命令的使用见 find 命令高效使用文章

第二步在 ~/.bashrc 中添加 mycscope 命令，添加完后，别忘记执行 source ~/.bashrc。

alias mycscope='source ~/.local/bin/cscope.sh'

第三部测试效果：

(*^~^*) ~/workbase/cix_linux/linux> mycscope/home/sam/workbase/linuxstart cscope....cscope -Rbkq -i cscope.filescscope finished(*^~^*) ~/workbase/cix_linux/linux> lsarch COPYING cscope.files cscope.out drivers init Kconfig LICENSES mm samples sound virtblock CREDITS cscope.in.out cscope.po.out fs ipc kernel MAINTAINERS net scripts toolscerts crypto cscope.log Documentation include Kbuild lib Makefile README security usr

从下图中可以看到通过cscope命令查找 函数定义定义时只显示了linux/arch 目录下的几个文件，滤除了上文中设置的那些目录：
