[20150427]tmux與INPUTRC定義衝突.txt

--我前一陣子發現在tmux裡面一些按鍵與INPUTRC衝突.

我的/etc/inputrc定義如下:

"\e[1~": beginning-of-line    # home
"\e[2~": yank-last-arg        # insert
"\e[3~": delete-char          # delete
"\e[4~": end-of-line          # end
"\e[5~": backward-kill-word   # page up
"\e[6~": kill-word            # page down

#set bell-style visible
set bell-style none
set meta-flag On
set convert-meta Off
set input-meta on
set output-meta On
set horizontal-scroll-mode On
set show-all-if-ambiguous On

# (F1 .. F5) are "\e[[A" ... "\e[[E"
#"\e[[B":  "select * from v$system_event ;"  # F2

"\e[[A": backward-word                     # F1
"\e[[B": forward-word                      # F2

"\e[[C": backward-kill-line                # F3
"\e[[D": kill-line                         # F4

"\e[[E": yank                              # F5
"\e[17~": undo                              # F6

"\e[18~": history-search-forward            # F7
"\e[19~": history-search-backward           # F8

"\e[20~": character-search                  # F9
"\e[21~": character-search-backward         # F10

"\e[23~": "\eb'\ef'"                        # F11
"\e[24~": kill-whole-line                   # F12

"\e[5C": forward-word
"\e[5D": backward-word
"\e[1;5C": forward-word
"\e[1;5D": backward-word

--不過我發現在tmux下無法使用F1,F2,F3,F4.

--進入tmux後執行:

--才發現進入TERM不再是linux,而是變成了screen.這樣一些按鍵的定義被重新修改.
--對比發現:
#  infocmp  screen linux | grep kf[123456]:
        kf1: '\EOP', '\E[[A'.
        kf2: '\EOQ', '\E[[B'.
        kf3: '\EOR', '\E[[C'.
        kf4: '\EOS', '\E[[D'.
        kf5: '\E[15~', '\E[[E'.

--可以發現F1,F2,F3,F4,F5的定義與原來不一致,這樣導致無法使用.為此我建立新的inputrc檔案.內容如下:
# cat /etc/tmux.inputrc
"\e[1~": beginning-of-line    # home
"\e[2~": yank-last-arg        # insert
"\e[3~": delete-char          # delete
"\e[4~": end-of-line          # end
"\e[5~": backward-kill-word   # page up
"\e[6~": kill-word            # page down

#set bell-style visible
set bell-style none
set meta-flag On
set convert-meta Off
set input-meta on
set output-meta On
set horizontal-scroll-mode On
set show-all-if-ambiguous On

# (F1 .. F5) are "\e[[A" ... "\e[[E"
#"\e[[B":  "select * from v$system_event ;"  # F2

"\eOP": backward-word                     # F1
"\eOQ": forward-word                      # F2

"\eOR": backward-kill-line                # F3
"\eOS": kill-line                         # F4

"\e[15~": yank                              # F5
"\e[17~": undo                              # F6

"\e[18~": history-search-forward            # F7
"\e[19~": history-search-backward           # F8

"\e[20~": character-search                  # F9
"\e[21~": character-search-backward         # F10

"\e[23~": "\eb'\ef'"                        # F11
"\e[24~": kill-whole-line                   # F12

--如何顯示進入tmux是指定INPUTRC=/etc/tmux.inputrc呢? 很簡單,修改.bashrc檔案加入如下:

if [[ '' = "$TMUX" ]]
then
    export INPUTRC=/etc/inputrc
else
    export INPUTRC=/etc/tmux.inputrc
fi

--這樣就可以正常實現功能鍵在兩種模式下正常使用了.
