perlwin32 Perl notes for Windows - - -By default, the manpages listed above are installed in the -F</usr/local/man/> directory. - -Extensive additional documentation for Perl modules is available. The -default configuration for perl will place this additional documentation -in the F</usr/local/lib/perl5/man> directory (or else in the F<man> -subdirectory of the Perl library directory). Some of this additional -documentation is distributed standard with Perl, but you'll also find -documentation for third-party modules there. - -You should be able to view Perl's documentation with your man(1) -program by including the proper directories in the appropriate start-up -files, or in the MANPATH environment variable. To find out where the -configuration has installed the manpages, type: - - perl -V:man.dir - -If the directories have a common stem, such as F</usr/local/man/man1> -and F</usr/local/man/man3>, you need only to add that stem -(F</usr/local/man>) to your man(1) configuration files or your MANPATH -environment variable. If they do not share a stem, you'll have to add -both stems. - -If that doesn't work for some reason, you can still use the -supplied F<perldoc> script to view module information. You might -also look into getting a replacement man program. - -If something strange has gone wrong with your program and you're not -sure where you should look for help, try the B<-w> switch first. It -will often point out exactly where the trouble is. - -=head1 DESCRIPTION - -Perl is a language optimized for scanning arbitrary -text files, extracting information from those text files, and printing -reports based on that information. It's also a good language for many -system management tasks. The language is intended to be practical -(easy to use, efficient, complete) rather than beautiful (tiny, -elegant, minimal). - -Perl combines (in the author's opinion, anyway) some of the best -features of C, B<sed>, B<awk>, and B<sh>, so people familiar with -those languages should have little difficulty with it. (Language -historians will also note some vestiges of B<csh>, Pascal, and even -BASIC-PLUS.) Expression syntax corresponds closely to C -expression syntax. Unlike most Unix utilities, Perl does not -arbitrarily limit the size of your data--if you've got the memory, -Perl can slurp in your whole file as a single string. Recursion is of -unlimited depth. And the tables used by hashes (sometimes called -"associative arrays") grow as necessary to prevent degraded -performance. Perl can use sophisticated pattern matching techniques to -scan large amounts of data quickly. Although optimized for -scanning text, Perl can also deal with binary data, and can make dbm -files look like hashes. Setuid Perl scripts are safer than C programs -through a dataflow tracing mechanism that prevents many stupid -security holes. - -If you have a problem that would ordinarily use B<sed> or B<awk> or -B<sh>, but it exceeds their capabilities or must run a little faster, -and you don't want to write the silly thing in C, then Perl may be for -you. There are also translators to turn your B<sed> and B<awk> -scripts into Perl scripts. - -But wait, there's more... - -Begun in 1993 (see L<perlhist>), Perl version 5 is nearly a complete -rewrite that provides the following additional benefits: - -=over 4 - -=item * - -modularity and reusability using innumerable modules - -Described in L<perlmod>, L<perlmodlib>, and L<perlmodinstall>. - -=item * - -embeddable and extensible - -Described in L<perlembed>, L<perlxstut>, L<perlxs>, L<perlcall>, -L<perlguts>, and L<xsubpp>. - -=item * - -roll-your-own magic variables (including multiple simultaneous DBM -implementations) - -Described in L<perltie> and L<AnyDBM_File>. - -=item * - -subroutines can now be overridden, autoloaded, and prototyped - -Described in L<perlsub>. - -=item * - -arbitrarily nested data structures and anonymous functions - -Described in L<perlreftut>, L<perlref>, L<perldsc>, and L<perllol>. - -=item * - -object-oriented programming - -Described in L<perlobj>, L<perlboot>, L<perltoot>, L<perltooc>, -and L<perlbot>. - -=item * - -support for light-weight processes (threads) - -Described in L<perlthrtut> and L<threads>. - -=item * - -support for Unicode, internationalization, and localization - -Described in L<perluniintro>, L<perllocale> and L<Locale::Maketext>. - -=item * - -lexical scoping - -Described in L<perlsub>. - -=item * - -regular expression enhancements - -Described in L<perlre>, with additional examples in L<perlop>. - -=item * - -enhanced debugger and interactive Perl environment, -with integrated editor support - -Described in L<perldebtut>, L<perldebug> and L<perldebguts>. - -=item * - -POSIX 1003.1 compliant library - -Described in L<POSIX>. - -=back - -Okay, that's I<definitely> enough hype. - -=head1 AVAILABILITY - -Perl is available for most operating systems, including virtually -all Unix-like platforms. See L<perlport/"Supported Platforms"> -for a listing. - -=head1 ENVIRONMENT - -See L<perlrun>. - -=head1 AUTHOR - -Larry Wall <larry@wall.org>, with the help of oodles of other folks. - -If your Perl success stories and testimonials may be of help to others -who wish to advocate the use of Perl in their applications, -or if you wish to simply express your gratitude to Larry and the -Perl developers, please write to perl-thanks@perl.org . - -=head1 FILES - - "@INC" locations of perl libraries - -=head1 SEE ALSO - - a2p awk to perl translator - s2p sed to perl translator - - http://www.perl.org/ the Perl homepage - http://www.perl.com/ Perl articles (O'Reilly) - http://www.cpan.org/ the Comprehensive Perl Archive - http://www.pm.org/ the Perl Mongers - -=head1 DIAGNOSTICS - -The C<use warnings> pragma (and the B<-w> switch) produces some -lovely diagnostics. - -See L<perldiag> for explanations of all Perl's diagnostics. The C<use -diagnostics> pragma automatically turns Perl's normally terse warnings -and errors into these longer forms. - -Compilation errors will tell you the line number of the error, with an -indication of the next token or token type that was to be examined. -(In a script passed to Perl via B<-e> switches, each -B<-e> is counted as one line.) - -Setuid scripts have additional constraints that can produce error -messages such as "Insecure dependency". See L<perlsec>. - -Did we mention that you should definitely consider using the B<-w> -switch? - -=head1 BUGS - -The B<-w> switch is not mandatory. - -Perl is at the mercy of your machine's definitions of various -operations such as type casting, atof(), and floating-point -output with sprintf(). - -If your stdio requires a seek or eof between reads and writes on a -particular stream, so does Perl. (This doesn't apply to sysread() -and syswrite().) - -While none of the built-in data types have any arbitrary size limits -(apart from memory size), there are still a few arbitrary limits: a -given variable name may not be longer than 251 characters. Line numbers -displayed by diagnostics are internally stored as short integers, -so they are limited to a maximum of 65535 (higher numbers usually being -affected by wraparound). - -You may mail your bug reports (be sure to include full configuration -information as output by the myconfig program in the perl source -tree, or by C<perl -V>) to perlbug@perl.org . If you've succeeded -in compiling perl, the B<perlbug> script in the F<utils/> subdirectory -can be used to help mail in a bug report. - -Perl actually stands for Pathologically Eclectic Rubbish Lister, but -don't tell anyone I said that. - -=head1 NOTES - -The Perl motto is "There's more than one way to do it." Divining -how many more is left as an exercise to the reader. - -The three principal virtues of a programmer are Laziness, -Impatience, and Hubris. See the Camel Book for why. - |
