.SH NAME

nanorc \- GNU nano's rcfile
|
|
.SH DESCRIPTION
|
|
This manual page briefly documents GNU \fBnano\fP's rcfile.
|
|
.PP
|
|
\fBnano\fP is a small, free and friendly editor which aims to replace
|
|
Pico, the default editor included in the non-free Pine package. Rather
|
|
than just copying Pico's look and feel, \fBnano\fP also implements some
|
|
missing (or disabled by default) features in Pico, such as "search and
|
|
replace" and "go to line and column number".
|
|
.PP
|
|
The \fInanorc\fP file contains the default settings for \fBnano\fP. It
|
|
should not be in DOS or Mac format. During startup, \fBnano\fP will
|
|
first read its system-wide settings from \fISYSCONFDIR/nanorc\fP, and
|
|
then user-specific settings from \fI~/.nanorc\fP.
|
|
|
|
.SH OPTIONS
|
|
The configuration file accepts a series of \fBset\fP and \fBunset\fP
|
|
commands, which can be used to configure nano on startup without using
|
|
the command line options. Additionally, the \fBsyntax\fP, \fBcolor\fP,
|
|
and \fBicolor\fP keywords are used to define syntax highlighting rules
|
|
for different text patterns. \fBnano\fP will read one command per line.
|
|
|
|
Options in \fInanorc\fP files take precedence over nano's defaults, and
|
|
command line options override \fInanorc\fP settings. Also, options are
|
|
unset by default, except for those that take arguments.
|
|
|
|
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 \fBbrackets\fP option, "\fI"')>]}\fP" will
|
|
match \fI"\fP, \fI'\fP, \fI)\fP, \fI>\fP, \fI]\fP, and \fI}\fP.
|
|
|
|
The supported commands and arguments are:
|
|
|
|

.B set quotestr "\fIstring\fP"
|

|
|
is an extended regular expression if your system supports them,
|
|
otherwise a literal string. The default value is
|
|
"\fI^([\ \\t]*[#:>\\|}])+\fP" if you have extended regular expression
|
|
support, or "\fI>\ \fP" otherwise. Note that '\\t' stands for a literal
|
|
Tab character.
|
|
.TP
|
|
.B set/unset rebinddelete
|
|
Interpret the Delete key differently so that both Backspace and Delete
|
|
work properly. You should only need to use this option if Backspace
|
|
acts like Delete on your system.
|
|
.TP
|
|
.B set/unset rebindkeypad
|
|
Interpret the numeric keypad keys so that they all work properly. You
|
|

|
Do extended regular expression searches by default.
|

|
|
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.
|
|

|
|
calls \fIspell\fP.
|
|
.TP
|
|
.B set/unset suspend
|
|
Allow \fBnano\fP to be suspended.
|
|
.TP
|
|
.B set tabsize \fIn\fP
|
|
Use a tab size of \fIn\fP columns. The value of \fIn\fP must be greater
|
|
than 0. The default value is 8.
|
|
.TP
|
|
.B set/unset tabstospaces
|
|

|
|
.TP
|
|
.B set whitespace "\fIstring\fP"
|
|

|
|
spaces. They must be single-column characters.

Detect word boundaries more accurately by treating punctuation
|
|
characters as parts of words.
|
|
.TP
|
|
.B syntax "\fIstr\fP" ["\fIfileregex\fP" ... ]
|
|
Defines a syntax named \fIstr\fP which can be activated via the
|
|
\-Y/\-\-syntax command line option, or will be automatically activated if
|
|
the current filename matches the extended regular expression
|
|
\fIfileregex\fP. All following \fBcolor\fP and \fBicolor\fP statements
|
|
will apply to \fIsyntax\fP until a new syntax is defined.
|
|
|
|
The \fInone\fP syntax is reserved; specifying it on the command line is
|
|
the same as not having a syntax at all. The \fIdefault\fP syntax is
|
|
special: it takes no \fIfileregex\fP, and applies to files that don't
|
|
match any other syntax's \fIfileregex\fP.
|
|
.TP
|
|
.B color \fIfgcolor\fP,\fIbgcolor\fP "\fIregex\fP" ...
|
|
For the currently defined syntax, display all expressions matching
|
|
the extended regular expression \fIregex\fP with foreground color
|
|
\fIfgcolor\fP and background color \fIbgcolor\fP, at least one of which
|
|
must be specified. Legal colors for foreground and background color
|
|
are: white, black, red, blue, green, yellow, magenta, and cyan. You may
|
|
use the prefix "bright" to force a stronger color highlight for the
|
|
foreground. If your terminal supports transparency, not specifying a
|
|
\fIbgcolor\fP tells \fBnano\fP to attempt to use a transparent
|
|
background.
|
|
.TP
|
|
.B icolor \fIfgcolor\fP,\fIbgcolor\fP "\fIregex\fP" ...
|
|
Same as above, except that the expression matching is case insensitive.
|
|
.TP
|
|
.B color \fIfgcolor\fP,\fIbgcolor\fP start="\fIsr\fP" end="\fIer\fP"
|
|
Display expressions which start with the extended regular expression
|
|
\fIsr\fP and end with the extended regular expression \fIer\fP with
|
|
foreground color \fIfgcolor\fP and background color \fIbgcolor\fP,
|
|
at least one of which must be specified. This allows syntax
|
|
highlighting to span multiple lines. Note that all subsequent instances
|
|
of \fIsr\fP after an initial \fIsr\fP is found will be highlighted until
|
|
the first instance of \fIer\fP.
|
|
.TP
|
|
.B icolor \fIfgcolor\fP,\fIbgcolor\fP start="\fIsr\fP" end="\fIer\fP"
|
|
Same as above, except that the expression matching is case insensitive.
|
|
.TP
|
|
.B include "\fIsyntaxfile\fP"
|
|
Read in self-contained color syntaxes from \fIsyntaxfile\fP. Note that
|
|
\fIsyntaxfile\fP can only contain \fBsyntax\fP, \fBcolor\fP, and
|
|
\fBicolor\fP commands.
|
|
.SH KEY BINDINGS
|
|
Key bindings may be reassigned via the following commands:
|
|
.TP
|
|
.B bind \fIkey\fP \fIfunction\fP \fImenu\fP
|
|
Rebinds the key \fIkey\fP to a new function named \fIfunction\fP in the
|
|
context of menu \fImenu\fP. The format of \fIkey\fP should be one of:
|
|
.TP
|
|
.B ^
|
|
followed by an alpha character or the word "Space".
|
|
Example: ^C
|
|
.TP
|

|
|
followed by a printable character or the word "Space".
|
|

|
|
