I am no longer using nano as my editor and hence have little motivation to continue working on this project. I will answer GitHub issues and fix existing bugs, but beyond that, please consider this repository only an archive.
Everything in the repository is in the Public Domain. Feel free to fork it and/or use the files for any purpose.
P.S. I highly recommend dex as a simple but much more capable editor.
The syntax highlighting definitions that come bundled with nano are of pretty poor quality. This is an attempt at providing a good set of accurate syntax definitions to replace and expand the defaults.
Using make install will concatenate and install the syntax definitions
to ~/.nano/syntax.nanorc and append an include command to
~/.nanorc, if necessary.
If your terminal text color isn't black, you'll need to specify it when
installing, using make install TEXT=color, where color must be one of:
red, green, yellow, blue, magenta, cyan or white.
After installation, use nano examples/* to test if everything is
working properly. If some or all of the files aren't highlighted properly,
see the FAQ below.
All *.nanorc files are passed through mixins.sed and theme.sed before
installation. These scripts allow rules to be specified in terms of token
names or mixins, instead of hard-coded colors.
For example, the following named rule:
TYPE: "int|bool|string"
becomes:
color green "int|bool|string"
and the following "mixin":
+BOOLEAN
becomes:
color brightcyan "\<(true|false)\>"
This system helps to keep colors uniform across different languages and also to keep the definitions clear and maintainable, which is something that becomes quite awkward using only plain nanorc files.
Note: if ~/.nanotheme exists it will be used as a custom theme, in
place of theme.sed. A custom theme may also be specified by installing
with make THEME=your-custom-theme.sed. Themes must be valid sed scripts,
defining all color codes found in theme.sed in order to work correctly.
There appears to be a bug in older versions of nano that causes
highlighting to fail when /etc/nanorc and ~/.nanorc both contain
syntax rules. The usual workaround is to remove all syntax and include
lines from /etc/nanorc.
In order to reliably highlight keywords, this projects makes heavy use of
the GNU regex word boundary extensions (\< and \>). BSD implementations
also have these extensions but use a different, incompatible syntax
([[:<:]] and [[:>:]]). Since version 2.1.5, nano can automatically
translate the GNU syntax to BSD syntax at run-time, but for the benefit of
people running a pre-2.1.5 version of nano on OS X or *BSD, the .nanorc
file itself can be translated by installing with make BSDREGEX=1.
Because nano compiles against the platform's native regex library and some
platforms don't support \s (as it's not required by POSIX ERE).
