使用vimdiff替換預設的'svn diff'

手動配置

第一步，配置 .vimrc

目标：vimdiff可以快速wrap很長的一行資訊自動換行

" ~/.vimrc

"BEGIN for vimdiff
func Wrap()
  set wrap
endfunc
map <F10> :call Wrap()<CR><C-W><C-W> :call Wrap()<CR><C-W><C-W>
imap <F10> <ESC>:call Wrap()<C-W><C-W> :call Wrap()<C-W><C-W>
"END for vimdiff
           

第二步，配置 ~/.subversion/config

目标：替換svn diff預設的對比工具為自定義的一個腳本，如果不爽，再改回來。

### Set diff-cmd to the absolute path of your 'diff' program.
###   Subversion's internal diff implementation.
# diff-cmd = diff_program (diff, gdiff, etc.)
diff-cmd = /home/xiwang/usr/local/bin/diffwrap.sh
           

第三步，建立/編輯 diffwrap.sh

目标：實作diffwrap.sh腳本，使執行指令'svn diff'時能正确執行此vimdiff指令。

#!/bin/bash

# diffwrap.sh

# ---BEGIN--- change
#shift 5
#vimdiff "$@"
DIFF="vimdiff"
LEFT=${6}
RIGHT=${7}

$DIFF $LEFT $RIGHT
# ----END---- change
           

腳本可以更新一下，通過環境變量DIFF來控制使用哪個diff指令，例如想要實用vimdiff的時候，就可以直接運作指令：export DIFF=vimdiff; 即可：

#!/bin/bash
# @input environment DIFF='diff'|'vimdiff'

# ---BEGIN--- change
# DIFF="diff"
# LEFT=${6}
# RIGHT=${7}
#
# $DIFF "$LEFT" "$RIGHT"

if [ x"$DIFF" == x"" ]; then
    DIFF="diff"; export DIFF
fi

LEFT=${6}
RIGHT=${7}

case "$DIFF" in
    "vimdiff")
        ;;
    "diff")
        OPTS="-Nu"
        ;;
esac

$DIFF "$LEFT" "$RIGHT" $OPTS
# ----END---- change
