nano/doc/nanorc.sample

## Sample initialization file for GNU nano.
##
## Please note that you must have configured nano with --enable-nanorc
## for this file to be read!  Also note that characters specially
## interpreted by the shell should not be escaped here.
##
## To make sure a value is not enabled, use "unset <option>"
##
## For the options that take parameters, the default value is given.
## Other options are unset by default.
##
## Quotes inside string parameters don't have to be escaped with
## backslashes.  The last double quote in the string will be treated as
## its end.  For example, for the brackets option, ""')>]}" will match
## ", ', ), >, ], and }.

## Use auto-indentation.
# set autoindent

## Backup files to filename~.
# set backup

## The directory to put unique backup files in.
# set backupdir ""

## Do backwards searches by default.
# set backwards

## The characters treated as closing brackets.  They cannot contain
## blank characters.  Only closing punctuation, optionally followed by
## closing brackets, can end sentences.
##
# set brackets ""')>]}"

## Do case sensitive searches by default.
# set casesensitive

## Constantly display the cursor position in the statusbar.  Note that
## this cancels out "quickblank".
# set const

## Use cut to end of line by default.
# set cut

## Set the line length for wrapping text and justifying paragraphs.
## If fill is 0 or less, the line length will be the screen width less
## this number.
##
# set fill -8

## Enable ~/.nano_history for saving and reading search/replace strings.
# set historylog

## The opening and closing brackets that can be found by bracket
## searches.  They cannot contain blank characters.  The former set must
## come before the latter set, and both must be in the same order.
##
# set matchbrackets "(<[{)>]}"

## Use the blank line below the titlebar as extra editing space.
# set morespace

## Enable mouse support, so that mouse clicks can be used to set the
## mark and run shortcuts.
# set mouse

## Allow multiple file buffers (inserting a file will put it into a
## separate buffer).  You must have configured with --enable-multibuffer
## for this to work.
##
# set multibuffer

## Don't convert files from DOS/Mac format.
# set noconvert

## Don't follow symlinks when writing files.
# set nofollow

## Don't display the helpful shortcut lists at the bottom of the screen.
# set nohelp

## Don't add newlines to the ends of files.
# set nonewlines

## Don't wrap text at all.
# set nowrap

## Set operating directory.  nano will not read or write files outside
## this directory and its subdirectories.  Also, the current directory
## is changed to here, so files are inserted from this dir.  A blank
## string means the operating directory feature is turned off.
##
# set operatingdir ""

## Preserve the XON and XOFF keys (^Q and ^S).
# set preserve

## The characters treated as closing punctuation.  They cannot contain
## blank characters.  Only closing punctuation, optionally followed by
## closing brackets, can end sentences.
##
# set punct "!.?"

## Do quick statusbar blanking.  Statusbar messages will disappear after
## 1 keystroke instead of 25.  Note that "const" cancels this out.
##
# set quickblank

## The email-quote string, used to justify email-quoted paragraphs.
## This is an extended regular expression if your system supports them,
## otherwise a literal string.  Default:
# set quotestr "^([ 	]*[#:>\|}])+"
## if you have regexps, otherwise:
# set quotestr "> "

## Fix Backspace/Delete confusion problem.
# set rebinddelete

## Fix numeric keypad key confusion problem.
# set rebindkeypad

## Do extended regular expression searches by default.
# set regexp

## Make the Home key smarter.  When Home is pressed anywhere but at the
## very beginning of non-whitespace characters on a line, the cursor
## will jump to that beginning (either forwards or backwards).  If the
## cursor is already at that position, it will jump to the true
## beginning of the line.
# set smarthome

## Use smooth scrolling as the default.
# set smooth

## Use this spelling checker instead of the internal one.  This option
## does not properly have a default value.
##
# set speller "aspell -x -c"

## Allow nano to be suspended.
# set suspend

## Use this tab size instead of the default; it must be greater than 0.
# set tabsize 8

## Convert typed tabs to spaces.
# set tabstospaces

## Save automatically on exit, don't prompt.
# set tempfile

## Disallow file modification; why would you want this in an rcfile? ;)
# set view

## The two single-column characters used to display the first characters
## of tabs and spaces.  187 decimal (0000BB hexadecimal) and 183 decimal
## (0000B7 hexadecimal) seem to be good values for these.
# set whitespace "  "

## Detect word boundaries more accurately by treating punctuation
## characters as part of a word.
# set wordbounds

## Color setup
##
## Format:
##
## syntax "short description" ["filename regex" ...]
##
## (The "none" syntax is reserved; specifying it on the command line is
## the same as not having a syntax at all.  The "default" syntax is
## special: it takes no filename regexes, and applies to files that
## don't match any other syntax's filename regexes.)
##
## color foreground,background "regex" ["regex"...]
## or
## icolor foreground,background "regex" ["regex"...]
##
## ("color" will do case sensitive matches, while "icolor" will do case
## insensitive matches.)
##
## Legal colors: white, black, red, blue, green, yellow, magenta, cyan.
## You may use the prefix "bright" to mean a stronger color highlight
## for the foreground.
##
## To use multi-line regexes, use the start="regex" end="regex"
## [start="regex" end="regex"...] format.
##
## If your system supports transparency, not specifying a background
## color will use a transparent color.  If you don't want this, be sure
## to set the background color to black or white.
