If you like Vim here is the Syntax Highlighter for Firebird SQL dialect (First version)

There is a github project pushed up here:

https://github.com/blumf/firebird_vim_syntax

Should be pretty simple for most *nix users to use.

sudo apt-get install lua5.2

git clone https://github.com/blumf/firebird_vim_syntax.git

cd firebird_vim_syntax

make

make install
