Arg_parser 1.1 (Stable branch)
Arg_parser is an argument parser that follows POSIX and GNU conventions for command line arguments. It is implemented as a C++ class, and is simpler, easier to use, and safer than "getopt_long". Arg_parser does not modify its arguments, nor uses any global variables. So you may create more than one parser in your program if you need or want to. Arg_parser can also parse options from configuration files. A C language version is also available. License: GNU General Public License v3 Changes:
A C language version has been added. Options requiring an argument no longer accept an empty argument.Image

CREATE TEXT SEARCH 
PARSER(7)					   SQL Commands 				      CREATE TEXT SEARCH PARSER(7)

NAME

       CREATE TEXT SEARCH PARSER - define a new text search parser

SYNOPSIS

       CREATE TEXT SEARCH PARSER name (
	   START = start_function ,
	   GETTOKEN = gettoken_function ,
	   END = end_function ,
	   LEXTYPES = lextypes_function
	   [, HEADLINE = headline_function ]
       )

DESCRIPTION

       CREATE  TEXT  SEARCH PARSER creates a new text search parser. A text search parser defines a method for splitting a text string into tokens
       and assigning types (categories) to the tokens.	A parser is not particularly useful by itself, but must be bound into a text  search  con-
       figuration along with some text search dictionaries to be used for searching.

       If a schema name is given then the text search parser is created in the specified schema. Otherwise it is created in the current schema.

       You  must  be  a  superuser to use CREATE TEXT SEARCH PARSER.  (This restriction is made because an erroneous text search parser definition
       could confuse or even crash the server.)

       Refer to in the documentation for further information.

PARAMETERS

       name   The name of the text search parser to be created. The name can be schema-qualified.

       start_function
	      The name of the start function for the parser.

       gettoken_function
	      The name of the get-next-token function for the parser.

       end_function
	      The name of the end function for the parser.

       lextypes_function
	      The name of the lextypes function for the parser (a function that returns information about the set of token types it produces).

       headline_function
	      The name of the headline function for the parser (a function that summarizes a set of tokens).

       The function names can be schema-qualified if necessary. Argument types are not given, since the argument list for each type of function is
       predetermined. All except the headline function are required.

       The arguments can appear in any order, not only the one shown above.

COMPATIBILITY

       There is no CREATE TEXT SEARCH PARSER statement in the SQL standard.
