I am trying to follow this example on the website:
http://ctags.sourceforge.net/EXTENDING.html

Creating a user-defined language
The quickest and easiest way to do this is by defining a new language
using the program options. In order to have Swine support available
every time I start ctags, I will place the following lines into the file
$HOME/.ctags, which is read in every time ctags starts: 

  --langdef=swine
  --langmap=swine:.swn
  --regex-swine=/^def[ \t]*([a-zA-Z0-9_]+)/\1/d,definition/


When I try the following I get an error:

ctags.exe -f - -e -V --langdef=sql --langmap=sql:.sql
--language-force=sql --regex-sql=/procedure[ \t]+(.*)/\1/n,name/i
dave.sql
  Option: --langdef=sql
  Option: --langmap=sql:.sql
    Setting sql language map: .sql
  Option: --language-force=sql
  Option: --regex-sql=/procedure[
ctags.exe: Warning: procedure[: incomplete regexp
Reading command line arguments
OPENING dave.sql as sql language file


Anytime I attempt to use ['s I get this error:
[: incomplete regexp

Any ideas?

Thanks,
Dave
