Nano syntax highlighting for C# and/or ASP.Net

Question

Has anyone got (or can point in the direction of) a nanorc file that contains syntax highlighting for C# and/or ASP.Net?

Answer 1

I don't know of an existing highlight for C# in Nano but you could write your own. The syntax for syntax highlighting is pretty simple. Here's the one for Java (which will be very similar to a C# syntax - mainly just different keywords):

## Here is an example for Java.
##
syntax "java" "\.java$"
color green "\<(boolean|byte|char|double|float|int|long|new|short|this|transient|void)\>"
color red "\<(break|case|catch|continue|default|do|else|finally|for|if|return|switch|throw|try|while)\>"
color cyan "\<(abstract|class|extends|final|implements|import|instanceof|interface|native|package|private|protected|public|static|strictfp|super|synchronized|throws|volatile)\>"
color red ""[^"]*""
color yellow "\<(true|false|null)\>"
color blue "//.*"
color blue start="/\*" end="\*/"
color brightblue start="/\*\*" end="\*/"
color ,green "[[:space:]]+$"

That's sitting in /usr/share/nano/java.nanorc. If you write your own you'll need to link to it from /etc/nanorc. There may be a user-local version of both too but I don't know it.

Edit: for ASP.NET you could just clone the HTML one and alter the syntax slightly to handle ASP.NET tags. It won't be perfect (it won't handle <script runat="server">...</script> contents for example) but it should be better than a poke in the eye with a sharp stick.

Using the Java example from http://wiki.linuxhelp.net/index.php/Nano_Syntax_Highlighting, you can try to add something like the following into your ~/.nanorc:

syntax "C# source" "\.cs$"
color green "\<(bool|byte|sbyte|char|decimal|double|float|int|uint|long|ulong|new|object|short|ushort|string|base|this|void)\>"
color red "\<(as|break|case|catch|checked|continue|default|do|else|finally|fixed|for|foreach|goto|if|is|lock|return|switch|throw|try|unchecked|while)\>"
color cyan "\<(abstract|class|const|delegate|enum|event|explicit|extern|implicit|in|internal|interface|namespace|operator|out|override|params|private|protected|public|readonly|ref|sealed|sizeof|static|struct|typeof|using|virtual|volatile)\>"
color red ""[^\"]*""
color yellow "\<(true|false|null)\>"
color blue "//.*"
color blue start="/\*" end="\*/"
color brightblue start="/\*\*" end="\*/"
color brightgreen,green " +$"
