18 | If you're new to Perl, you should start with L<perlintro>, which is a |
19 | general intro for beginners and provides some background to help you | |
20 | navigate the rest of Perl's extensive documentation. | |
21 | ||
22 | For ease of access, the Perl manual has been split up into several sections. | |

19799a22 | 223 | By default, the manpages listed above are installed in the |
fc952dec CS |
224 | F</usr/local/man/> directory. |
225 | ||
226 | Extensive additional documentation for Perl modules is available. The | |
227 | default configuration for perl will place this additional documentation | |
228 | in the F</usr/local/lib/perl5/man> directory (or else in the F<man> | |
229 | subdirectory of the Perl library directory). Some of this additional | |
230 | documentation is distributed standard with Perl, but you'll also find | |
231 | documentation for third-party modules there. | |
232 | ||
233 | You should be able to view Perl's documentation with your man(1) | |
234 | program by including the proper directories in the appropriate start-up | |
235 | files, or in the MANPATH environment variable. To find out where the | |
236 | configuration has installed the manpages, type: | |
16d20bd9 | 237 | |
760ac839 | 238 | perl -V:man.dir |
16d20bd9 | 239 | |
fc952dec CS |
240 | If the directories have a common stem, such as F</usr/local/man/man1> |
241 | and F</usr/local/man/man3>, you need only to add that stem | |
242 | (F</usr/local/man>) to your man(1) configuration files or your MANPATH | |
243 | environment variable. If they do not share a stem, you'll have to add | |
244 | both stems. | |
16d20bd9 AD |
245 | |
246 | If that doesn't work for some reason, you can still use the | |
4633a7c4 LW |
247 | supplied F<perldoc> script to view module information. You might |
248 | also look into getting a replacement man program. | |
16d20bd9 | 249 | |
a0d0e21e LW |
250 | If something strange has gone wrong with your program and you're not |
251 | sure where you should look for help, try the B<-w> switch first. It | |
252 | will often point out exactly where the trouble is. | |
253 | ||
254 | =head1 DESCRIPTION | |
255 | ||
5f05dabc | 256 | Perl is a language optimized for scanning arbitrary |
a0d0e21e LW |
257 | text files, extracting information from those text files, and printing |
258 | reports based on that information. It's also a good language for many | |
259 | system management tasks. The language is intended to be practical | |
260 | (easy to use, efficient, complete) rather than beautiful (tiny, | |
94d58c47 | 261 | elegant, minimal). |
262 | ||
aa689395 | 263 | Perl combines (in the author's opinion, anyway) some of the best |
264 | features of C, B<sed>, B<awk>, and B<sh>, so people familiar with | |
265 | those languages should have little difficulty with it. (Language | |
266 | historians will also note some vestiges of B<csh>, Pascal, and even | |
14218588 | 267 | BASIC-PLUS.) Expression syntax corresponds closely to C |
a0d0e21e LW |
268 | expression syntax. Unlike most Unix utilities, Perl does not |
269 | arbitrarily limit the size of your data--if you've got the memory, | |
aa689395 | 270 | Perl can slurp in your whole file as a single string. Recursion is of |
0f31cffe | 271 | unlimited depth. And the tables used by hashes (sometimes called |
aa689395 | 272 | "associative arrays") grow as necessary to prevent degraded |
0f31cffe | 273 | performance. Perl can use sophisticated pattern matching techniques to |
14218588 | 274 | scan large amounts of data quickly. Although optimized for |
aa689395 | 275 | scanning text, Perl can also deal with binary data, and can make dbm |
276 | files look like hashes. Setuid Perl scripts are safer than C programs | |
14218588 | 277 | through a dataflow tracing mechanism that prevents many stupid |
aa689395 | 278 | security holes. |
279 | ||
280 | If you have a problem that would ordinarily use B<sed> or B<awk> or | |
281 | B<sh>, but it exceeds their capabilities or must run a little faster, | |
282 | and you don't want to write the silly thing in C, then Perl may be for | |
283 | you. There are also translators to turn your B<sed> and B<awk> | |
284 | scripts into Perl scripts. | |
a0d0e21e LW |

286 | But wait, there's more... | |

406 | =head1 DIAGNOSTICS |

408 | The C<use warnings> pragma (and the B<-w> switch) produces some |
409 | lovely diagnostics. | |
a0d0e21e | 410 | |
5a964f20 TC |
411 | See L<perldiag> for explanations of all Perl's diagnostics. The C<use |
412 | diagnostics> pragma automatically turns Perl's normally terse warnings | |
413 | and errors into these longer forms. | |
a0d0e21e LW |
414 | |
415 | Compilation errors will tell you the line number of the error, with an | |
416 | indication of the next token or token type that was to be examined. | |
14218588 | 417 | (In a script passed to Perl via B<-e> switches, each |
a0d0e21e LW |
418 | B<-e> is counted as one line.) |
419 | ||
420 | Setuid scripts have additional constraints that can produce error | |
421 | messages such as "Insecure dependency". See L<perlsec>. | |
422 | ||
423 | Did we mention that you should definitely consider using the B<-w> | |
424 | switch? | |
425 | ||
426 | =head1 BUGS | |
427 | ||
428 | The B<-w> switch is not mandatory. | |
429 | ||
430 | Perl is at the mercy of your machine's definitions of various | |
1b3f7d21 CS |
431 | operations such as type casting, atof(), and floating-point |
432 | output with sprintf(). | |
a0d0e21e | 433 | |
748a9306 | 434 | If your stdio requires a seek or eof between reads and writes on a |
a0d0e21e LW |
435 | particular stream, so does Perl. (This doesn't apply to sysread() |
436 | and syswrite().) | |
437 | ||
438 | While none of the built-in data types have any arbitrary size limits | |
439 | (apart from memory size), there are still a few arbitrary limits: a | |
a30ac152 GS |
440 | given variable name may not be longer than 251 characters. Line numbers |
441 | displayed by diagnostics are internally stored as short integers, | |
442 | so they are limited to a maximum of 65535 (higher numbers usually being | |
443 | affected by wraparound). | |
a0d0e21e | 444 | |
b0607b7a | 445 | You may mail your bug reports (be sure to include full configuration |
19799a22 | 446 | information as output by the myconfig program in the perl source |
7f2de2d2 | 447 | tree, or by C<perl -V>) to perlbug@perl.org . If you've succeeded |
055fd3a9 | 448 | in compiling perl, the B<perlbug> script in the F<utils/> subdirectory |
19799a22 | 449 | can be used to help mail in a bug report. |

451 | Perl actually stands for Pathologically Eclectic Rubbish Lister, but |
452 | don't tell anyone I said that. | |

454 | =head1 NOTES | |
455 | ||
456 | The Perl motto is "There's more than one way to do it." Divining | |
457 | how many more is left as an exercise to the reader. | |
458 | ||
4633a7c4 | 459 | The three principal virtues of a programmer are Laziness, |
a0d0e21e | 460 | Impatience, and Hubris. See the Camel Book for why. |
