Colorizing Nano

[Syngin]

I came across this and thought it might be really helpful to some people. If you use nano (pico clone) as your text editor, the following link will show you how to colorize the code.

Very handy.

Basically, create a file called .nanorc in the root of your home directory and paste something like the following into it and Presto!, colorized code (NOTE: each line should start with either a #, syntax or color (the forum is doing some annoying text wrapping):

#PHP
syntax "php" "\.php[2345s~]?$"
color brightblue "(.*)\("
color white "\$[a-zA-Z_0-9$]*|[=!<>]"
color green "(var|class|function|echo|case|break|default|exit|s witch|if|else|elseif|@|while)\s"
color green "[.,{}();]"
color red "('.*')|(\".*\")"
color brightyellow "(#.*|//.*)$"
color brightyellow start="/\*" end="\*/"
color brightred "(<\?(php)?|\?>)"
color white start="\?>" end="<\?(php)?"

Will be very useful. Something that I can use.;)

[loopback48]

Can I just copy and past your example? And just what correction will I have to do, if any to it? Or can you correct it?

Also, can you give an example of the end result? Like to see it.

Thanks.

Thanks I've been working with C trying to learn it, so I started using emacs because it colors code but nano is my editor of choice.

No editor wars please ... but ..
why not use vim ?
it has
It's as easy as :sy on
and you have color in Vim.
And you can also use it as a full blown IDE with Vim Project wich you can
find here http://code.google.com/p/perlhobby/ with instructions how to install
it and a screenshot to see if it fits your needs.

[JohnT]

Not as much an editor issue, but more of a "what's included with my distro" issue. Nano/Pico are the two most common that are available with a new setup.

[spx2]

oh yes...thats true...then again I consider vim as a default editor,from my point of view at least...

Nice, in Debian to get vim with this feature I had to install vim-full

apt-get install vim-full

Thanks
