message.
doubleescape When set, two consecutive ESC (escape) characters are required to leave input mode.
In input mode, a single ESC character followed by a different character causes vi to
issue an audibleor visual warning (see the flash editor option) and insert both char-
acters into the work area. Reversed by nodoubleescape. The default is
nodoubleescape.
The character sequences transmitted by the keyboard editing keys of some terminals
are identical to some sequences of vi user commands. If the mapping of these keys is
enabled (see the keyboardedit and keyboardedit! options), vi might not be
able to reliably distinguish between the character sequence transmitted by an editing
key and the same character sequence typed by a user. This problem is most likely to
occur when the user types ESC to terminate input mode immediately followed by
another vi command. If you set the doubleescape option, the ambiguity of this
case is removed.
edcompatible (ed)
Cause the presence of g and c suffixes on substitute commands to be remembered,
and toggled by repeating the suffixes. Reversed by
noedcompatible (noed
).
The default is
noedcompatible
.
errorbells (eb) When set, error messages are preceded with a bell only on terminals that do not sup-
port a standout or highlighting mode such as inverse video. If the terminal supports
highlighting, the bell is never used prior to error messages and this option has no
effect. Note that visual-mode errors are signaled by the bell (regardless of the setting
of this option) without an accompanying error message.
Reversed by noerrorbells (noeb). The default is noerrorbells .
exrc When set, the .exrc file in the current directory is processed during editor initializa-
tion if the current directory is not the HOME directory. This option is not set by
default and must be set in the EXINIT environment variable or the HOME directory
.exrc file to have any effect. See the Editor Options introductory text above.
Reversed by noexrc. The default is noexrc.
flash (fl) When set, the screen flashes instead of beeping, provided an appropriate
flash_screen entry is present in the /usr/share/lib/terminfo
database
for the terminal being used. Reversed by
noflash (nofl). The default is flash.
hardtabs=number (ht)
Define the spacing between hardware tab settings and the number of spaces used by
the system when expanding tab characters. Tab stops are placed in each column
number (starting at the left edge of the screen) that corresponds to an integer multi-
ple of number. The default is hardtabs=8.
ignorecase (ic) All uppercase characters in the text are mapped to lowercase in regular expression
matching. Also, all uppercase characters in regular expressions are mapped to lower-
case, except in character class specifications. Reversed by noignorecase (noic).
The default is noignorecase .
keyboardedit When set, any keyboard editing key mappings that are loaded automatically at initial-
ization for command-mode use are enabled. If not set, these mappings are disabled
(but not deleted). Use the map command to get a list of the currently enabled
command-mode mappings. Reversed by nokeyboardedit
. The default is key-
boardedit
.
keyboardedit! When set, the keyboard editing key mappings automatically loaded at initialization for
input mode use are enabled. If not set, these mappings are disabled (but not deleted).
Use the map! command to list the currently enabled input-mode mappings. Reversed
by nokeyboardedit!. The default is nokeyboardedit!
for terminals whose
keyboard editing keys send HP-style escape sequences (an ESC followed by a single
letter). The default is
keyboardedit! for all other terminals.
lisp Modify autoindent mode and the (, ), [[, ]], {, and } commands in visual mode
for lisp source code. Reversed by nolisp. The default is nolisp.
list Display all printed lines with tabs shown as ˆI, and the end of line marked by a
$.
Reversed by
nolist. The default is nolist.
