There is only one source file from the ctags distribuition which
must be modified: parsers.h

What does ctags report when you run "ctags -V"? This should report
the initialization of each language.

[Ctags] Problems with --regexp - Warning: procedure[: incomplete regexp

[David Fishburn <fishburn@sy...>]

Exuberant Ctags 5.3, Copyright (C) 1996-2002 Darren Hiebert
  Compiled: Jul 17 2002, 19:00:48
  Addresses: <dhiebert@...>,
http://ctags.sourceforge.net
  Optional compiled features: +win32, +regex, +internal-sort

W2K

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

Well, on Unix, it would be essential to quote the regex in order to
prevent shell substitution on special characters (like ' '). It
looks like the space in your regex is causing the regex argument to
be broken up into two separate arguments. You probably need to quote
it on Win 2000 also (I think double-quotes should work). Quoting is
unnecessary when the options are placed into a ctags.cnf file (on
Windows; see the man page). Try this:

    ctags.exe -f - -e -V --langdef=sql --langmap=sql:.sql --language-force=sql --regex-sql="/procedure[ \t]+(.*)/\1/n,name/i" dave.sql

   On 'Doze, I'd actually recommend quoting the whole arg., whih, 
although not the *nix norm, works better under 'Doze with it's more 
simplistic argument processing:

   "--regex-sql=/procedure[ \t]+(.*)/\1/n,name/i"

RE: [Ctags] Problems with --regexp - Warning: procedure[: incomplete regexp

[David Fishburn <fishburn@sy...>]

Thanks for the help, this got me much farther.

    ctags.exe -f - -e -V --langdef=sql --langmap=sql:.sql
--language-force=sql --regex-sql="/procedure[ \t]+(.*)/\1/n,name/i"
dave.sql

The double quotes around the --regex-sql expression worked great.

Now I have an additional problem.

In my expression, I want to add a check for double quotes (in the
expression).

So I tried this:
--regex-sql="/procedure[ \t]+\"?(.*)/\1/n,name/i" 

I added a
\"?

I used the \ to escape the ".

Problem though is ctags is still reading the \" as a double quote, so it
is prematurely cutting off the expression.

Any ideas?
How do you esacape " in expressions?

Thanks,
Dave

[Ctags] Adding a new language - compiling and miscellaneous

[David Fishburn <fishburn@sy...>]

Well, thanks to the suggestions from people on this list I have
successfully added a new language to my ctags.cnf file (W2K).

Now I would like to add it to the source as well and make it
permanenantly part of ctags.

I have found that slang.c is basically the same as my sql.c.  So I
copied it and make the changes.
I am using Microsoft VS to compile, so I used the mk_mvc.mak file.

I have updated source.mak to include the new module.
I have updated parsers.h to include the new parser function.

But when I run the new ctags.exe it says:
ctags.exe -f - --format=2 --excmd=pattern --fields=nK  --sort=no
--language-force=sql --sql-types=p "dave.sql"
ctags.exe: Uknown language specified in "language-force" option


Can anyone tell me which file I have missed to add the new language.

Once I have it working I will have to find out how to get this language
"officially" added.

Thanks,
Dave

RE: [Ctags] Adding a new language - compiling and miscellaneous

[David Fishburn <fishburn@sy...>]

Here is my sql.c file.

/* INCLUDE FILES */
#include "general.h"    /* always include first */
#include "parse.h"      /* always include */

/* FUNCTION DEFINITIONS */

static void installSqlRegex (const langType language)
{
    addTagRegex (language, "^def[ \t]*([a-zA-Z0-9_]+)", "\\1",
"d,definition", NULL);
    //addTagRegex (language, "^[ \t]*create[ \t]+([a-zA-Z0-9_]+)",
"\\1", "t,table", NULL);
    addTagRegex (language, "^[ \t]*create[ \t]+([a-zA-Z0-9
\t]*)?(table)[ \t]+([^.]+\.)?([a-zA-Z0-9_@...]+)", "\\4", "t,table",
NULL);
    addTagRegex (language, "^[ \t]*create[ \t]+([a-zA-Z0-9
\t]*)?(procedure|package)[ \t]+([^.]+\.)?([a-zA-Z0-9_@...]+)", "\\4",
"p,procedure", NULL);
}

/* Create parser definition stucture */
extern parserDefinition* SqlParser (void)
{
    static const char *const extensions [] = { "sql", NULL };
    parserDefinition* def = parserNew ("Sql");
    //parserDefinition* const def = parserNew ("Makefile");
    //def->patterns   = patterns;
    def->extensions = extensions;
    def->initialize = installSqlRegex;
    def->regex      = TRUE;
    return def;
}


I updated parsers.h and added this entry between these others:
    SlangParser, \
    SqlParser, \
    TclParser, \


I updated source.mak so that it would also compile the sql.c file.

When I run the make file in MVC, it does compile the sql.c and creates
the sql.obj.

But when I run ctags -V
