<H2>DESCRIPTION</H2>
|
|
|
|
This manual page documents briefly the <B>nano</B> command.
|
|
<P>
|
|
|
|
|
|
|
|
|
|
<B>nano</B> 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, <B>nano</B> also implements some
|
|
missing (or disabled by default) features in Pico, such as "search and
|
|
replace" and "go to line number".

<H2>INITIALIZATION FILE</H2>
|
|
|
|
<B>nano</B> will read initialization files in the following
|
|
order: $SYSCONFDIR/nanorc, then ~/.nanorc. Please see the example
|
|
file <B>nanorc.sample</B> which should be provided with <B>nano</B>.
|
|
All lines beginning with a hash symbol (
|
|
#
|
|
) are considered comments
|
|
and will be ignored. The following commands are understood in the
|
|
initialization file:
|
|
<DL COMPACT>
|
|
<DT><B>[un]set </B><I>option</I> [<I>value</I>]
|
|
|
|
<DD>
|
|
Set (or unset) the flag <I>option</I>. Any long option listed above can
|
|
be set or unset by removing the leading dashes (e.g. "set nowrap"). If
|
|
the option takes an argument it will be set to <I>value</I>.
|
|
</DL>
|

|

|

<B>COLOR SYNTAX HIGHLIGHTING</B> (if supported by your curses library)
|
|
<P>
|
|
|
|
<DL COMPACT>
|
|
<DT><B>syntax </B><I>str</I> [<I>fileregex</I> ... ]
|
|
|
|
<DD>
|
|
Defines a syntax named <I>str</I> which can be activated via the
|
|
<B>-Y</B> flag, or will be automatically activated if the current
|
|
filename matches <I>fileregex</I>. All following <B>color</B> statements
|
|
will apply to <I>syntax</I> until a new syntax is defined.
|
|
<DT><B>color </B><I>fgcolor</I>[,<I>bgcolor</I>] <I>regex</I> ...
|
|
|
|
<DD>
|
|
For the currently defined syntax, display all expressions matching
|
|
<I>regex</I> with foreground color <I>fgcolor</I> and optional background
|
|
color <I>bgcolor</I>. 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. If your
|
|
terminal supports transparency, not specifying a <I>bgcolor</I> tells
|
|
<B>nano</B> to attempt to use a transparent background.
|
|
<DT><B>color </B><I>fgcolor</I>[,<I>bgcolor</I>] start=<I>sr</I> end=<I>er</I>
|
|
|
|
<DD>
|
|
Display expressions which start with <I>sr</I> and end with <I>er</I>
|
|
with foreground color <I>fgcolor</I> and optional
|
|
background color <I>bgcolor</I>. This allows syntax highlighting to span
|
|
multiple lines. Note that all subsequent instances of <I>sr</I> after
|
|
an initial <I>sr</I> is found will be highlighted until the first
|
|
instance of <I>er</I>.

<H2>NOTES</H2>
|
|
|
|
<B>nano</B> will try to dump the buffer into an emergency file in some
|
|
cases. Mainly, this will happen if <B>nano</B> receives a SIGHUP or
|
|
SIGTERM or runs out of memory, when it will write the buffer into a file
|
|
named "nano.save" if the buffer didn't have a name already, or will add
|
|
a ".save" suffix to the current filename. If an emergency file with that
|
|
name already exists in the current directory, ".save" and a number (e.g.
|
|
".save.1") will be suffixed to the current filename in order to make it
|
|
unique. In multibuffer mode, <B>nano</B> will write all the open buffers
|
|
to the respective emergency files.
