Cscope
cd /usr/ports/devel/cscope/
make & make install





configure

At first we shoudl check the vim configure as following:
vim --version | grep cscope
If it is existed, we can install vim without others.
But if not so, we should install cscope and reconfigure vim makefile.






making cscope

find | grep "\.c$\|\.h$" > cscope.files

or 

# for current directory.

ls | grep "\.c$|\.h$" > cscope.files


cscope -b 
ctag -L cscope.files
;ctag is exuberant-ctags
ctag -n --fields=+ai -L cscop.files

ctags --c-kinds=+p -R /usr/include  or makeing ctags file in /usr/include


# for php
ctags --php-kinds=+cidfv -R . ../php/PEAR
# --{lag}-kindsは、ctags --list-kindsで詳細がわかる






  1. Ctrl-\ c : find the callers of a routine.
    2. 

  2. Ctrl-\ s : find the uses of a symbol
    3. 

  3. Ctrl-[ Ctrl-[ s : vertical split find the uses of a symbol
    4. 

  4. To update a cscope database without closing vim :!cscope -b, then :cs reset
    5.


Clewn

vim + gdb
What I also needed was the libncurses5 and libncurses5-dev packages.
4.1 Default mappings:
List of default key mappings:
CTRL-Z  send an interrupt to GDB and the program it is running
       B       info breakpoints
       L       info locals
       A       info args
       S       step
       I       stepi
       CTRL-N  next: next source line, skipping all function calls
       X       nexti
       F       finish
       R       run
       Q       quit
       C       continue
       W       where
       CTRL-U  up: go up one frame
       CTRL-D  down: go down one frame
cursor position: 
CTRL-B  set a breakpoint on the line where the cursor is located
       CTRL-E  clear all breakpoints on the line where the cursor is located
mouse pointer position: 
CTRL-P  print the value of the variable defined by the mouse pointer
               position
       CTRL-X  print the value that is referenced by the address whose
               value is that of the variable defined by the mouse pointer
               position
       CTRL-K  set a breakpoint at assembly address shown by mouse position
       CTRL-H  clear a breakpoint at assembly address shown by mouse position
       CTRL-J  add the selected variable at mouse position to the watched
               variables window
Note: You can tune Vim behavior when using netBeans keys with the mouse
pointer position, by setting Vim balloondelay to a smaller value than its
default. The following setting has been reported to give better results:
:set balloondelay=100 ~
Note: After browsing your code, you can always return rapidly to the line of
code where GDB is currently stopped, by using CTRL-U and CTRL-D.

nginx로 다중 포트 설정 및 다중 react app 설정

nginx에 다중 포트 설정하기 react로 여러 webapp를 개발하고, 동일한 서버에 실행시킬 필요가 있다. 이때 간단히 nginx에서 다중포트로 여러 webapp를 동일한 서버에서 실행시킬 수 있다. /etc/nginx/sites-available/에 default 파일이 있다. 보통 port 80로 설정되어 있다. 이 파일을 복사해서 sub로 명명한다.   아래와 같이 포트 8080으로 정하고, react app를 build한 디렉터리를 root <dir>로 지정하고, $> sudo service nginx restart 하면 된다. $>sudo systemctl status nginx.service 로 nginx 상태 확인이 가능하면, $> netstat -ano | grep 8080 으로 8080 포트가 살아있는 또는 외부PC에서  $>telnet ip 8080으로 telnet 접속이 되는지 확인하면 된다. 종종 Nginx 500 Interval Server Error가 발생하는데, 이는 1) root <dir>에서 <dir> 주소가 정확하지 않거나, 2) 파일 권한이 없거나이다. chmod 755 <dir>하면 대부분 해결될 것이다. 그럼 오늘도 유익한 하루 되시길..
