| Project Status | ||
| ============== | ||
|
|
||
| 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](https://github.com/tihirvon/dex) as a | ||
| simple but much more capable editor. | ||
|
|
||
|
|
||
| ------ | ||
|
|
||
|
|
||
| Description | ||
| ----------- | ||
|
|
||
| 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. | ||
|

||
|  | ||
|
|
||
| Installation | ||
| ------------ | ||
|
|
||
| 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. | ||
|
|
||
| Theme System | ||
| ------------ | ||
|
|
||
| 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. | ||
|
|
||
| FAQ | ||
| ---- | ||
|
|
||
| ### Why does syntax highlighting only work for a subset of supported files? | ||
|
|
||
| There appears to be a [bug][issue #5] 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`. | ||
|
|
||
| ### Why do I get wierd errors when running nano < 2.1.5 on *BSD systems? | ||
|
|
||
| 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`. | ||
|
|
||
| ### Why not use `\s` instead of the verbose `[[:space:]]` pattern? | ||
|
|
||
| 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]). | ||
