268=head1 NAME
269
270SQL::Translator::Utils - SQL::Translator Utility functions
271
272=head1 SYNOPSIS
273
274 use SQL::Translator::Utils qw(debug);
275 debug("PKG: Bad things happened");
276
277=head1 DESCSIPTION
278
279C<SQL::Translator::Utils> contains utility functions designed to be
280used from the other modules within the C<SQL::Translator> modules.
281
282Nothing is exported by default.
283
284=head1 EXPORTED FUNCTIONS AND CONSTANTS
285
286=head2 debug
287
288C<debug> takes 0 or more messages, which will be sent to STDERR using
289C<warn>. Occurances of the strings I<PKG>, I<SUB>, and I<LINE>
290will be replaced by the calling package, subroutine, and line number,
291respectively, as reported by C<caller(1)>.
292
293For example, from within C<foo> in F<SQL/Translator.pm>, at line 666:
294
295 debug("PKG: Error reading file at SUB/LINE");
296
297Will warn
298
299 [SQL::Translator: Error reading file at foo/666]
300
301The entire message is enclosed within C<[> and C<]> for visual clarity
302when STDERR is intermixed with STDOUT.
303
304=head2 normalize_name
305
306C<normalize_name> takes a string and ensures that it is suitable for
307use as an identifier. This means: ensure that it starts with a letter
308or underscore, and that the rest of the string consists of only
309letters, numbers, and underscores. A string that begins with
310something other than [a-zA-Z] will be prefixer with an underscore, and
311all other characters in the string will be replaced with underscores.
312Finally, a trailing underscore will be removed, because that's ugly.
313
314 normalize_name("Hello, world");
315
316Produces:
317
318 Hello_world
319
320A more useful example, from the C<SQL::Translator::Parser::Excel> test
321suite:
322
323 normalize_name("silly field (with random characters)");
324
325returns:
326
327 silly_field_with_random_characters
328
329=head2 header_comment
330
331Create the header comment. Takes 1 mandatory argument (the producer
332classname), an optional comment character (defaults to $DEFAULT_COMMENT),
333and 0 or more additional comments, which will be appended to the header,
334prefixed with the comment character. If additional comments are provided,
335then a comment string must be provided ($DEFAULT_COMMENT is exported for
336this use). For example, this:
337
338 package My::Producer;
339
340 use SQL::Translator::Utils qw(header_comment $DEFAULT_COMMENT);
341
342 print header_comment(__PACKAGE__,
343 $DEFAULT_COMMENT,
344 "Hi mom!");
345
346produces:
347
348 --
349 -- Created by My::Prodcuer
350 -- Created on Fri Apr 25 06:56:02 2003
351 --
352 -- Hi mom!
353 --
354
355Note the gratuitous spacing.
356
357=head2 parse_list_arg
358
359Takes a string, list or arrayref (all of which could contain
360comma-separated values) and returns an array reference of the values.
361All of the following will return equivalent values:
362
363 parse_list_arg('id');
364 parse_list_arg('id', 'name');
365 parse_list_arg( 'id, name' );
366 parse_list_arg( [ 'id', 'name' ] );
367 parse_list_arg( qw[ id name ] );
368
369=head2 truncate_id_uniquely
370
371Takes a string ($desired_name) and int ($max_symbol_length). Truncates
372$desired_name to $max_symbol_length by including part of the hash of
373the full name at the end of the truncated name, giving a high
374probability that the symbol will be unique. For example,
375
376 truncate_id_uniquely( 'a' x 100, 64 )
377 truncate_id_uniquely( 'a' x 99 . 'b', 64 );
378 truncate_id_uniquely( 'a' x 99, 64 )
379
380Will give three different results; specifically:
381
382 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa_7f900025
383 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa_6191e39a
384 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa_8cd96af2
385
386=head2 $DEFAULT_COMMENT
387
388This is the default comment string, '-- ' by default. Useful for
389C<header_comment>.
390
391=head2 parse_mysql_version
392
393Used by both L<Parser::MySQL|SQL::Translator::Parser::MySQL> and
394L<Producer::MySQL|SQL::Translator::Producer::MySQL> in order to provide a
395consistent format for both C<< parser_args->{mysql_parser_version} >> and
396C<< producer_args->{mysql_version} >> respectively. Takes any of the following
397version specifications:
398
399 5.0.3
400 4.1
401 3.23.2
402 5
403 5.001005 (perl style)
