163 | .SH "DESCRIPTION" | |
164 | .IX Header "DESCRIPTION" | |
165 | The Config module contains all the information that was available to | |
166 | the \f(CW\*(C`Configure\*(C'\fR program at Perl build time (over 900 values). | |
167 | .PP | |
168 | Shell variables from the \fIconfig.sh\fR file (written by Configure) are | |
169 | stored in the readonly-variable \f(CW%Config\fR, indexed by their names. | |
170 | .PP | |
171 | Values stored in config.sh as 'undef' are returned as undefined | |
172 | values. The perl \f(CW\*(C`exists\*(C'\fR function can be used to check if a | |
173 | named variable exists. | |
174 | .IP "\fImyconfig()\fR" 4 | |
175 | .IX Item "myconfig()" | |
176 | Returns a textual summary of the major perl configuration values. | |
177 | See also \f(CW\*(C`\-V\*(C'\fR in \*(L"Switches\*(R" in perlrun. | |
178 | .IP "\fIconfig_sh()\fR" 4 | |
179 | .IX Item "config_sh()" | |
180 | Returns the entire perl configuration information in the form of the | |
181 | original config.sh shell variable assignment script. | |
182 | .IP "config_re($regex)" 4 | |
183 | .IX Item "config_re($regex)" | |
184 | Like \fIconfig_sh()\fR but returns, as a list, only the config entries who's | |
185 | names match the \f(CW$regex\fR. | |
186 | .IP "config_vars(@names)" 4 | |
187 | .IX Item "config_vars(@names)" | |
188 | Prints to \s-1STDOUT\s0 the values of the named configuration variable. Each is | |
189 | printed on a separate line in the form: | |
190 | .Sp | |
191 | .Vb 1 | |
192 | \& name='value'; | |
193 | .Ve | |
194 | .Sp | |

226 | .SH "WARNING" | |
227 | .IX Header "WARNING" | |
228 | Because this information is not stored within the perl executable | |
229 | itself it is possible (but unlikely) that the information does not | |
230 | relate to the actual perl binary which is being used to access it. | |
231 | .PP | |
232 | The Config module is installed into the architecture and version | |
233 | specific library directory ($Config{installarchlib}) and it checks the | |
234 | perl version number when loaded. | |
235 | .PP | |
236 | The values stored in config.sh may be either single-quoted or | |
237 | double\-quoted. Double-quoted strings are handy for those cases where you | |
238 | need to include escape sequences in the strings. To avoid runtime variable | |
239 | interpolation, any \f(CW\*(C`$\*(C'\fR and \f(CW\*(C`@\*(C'\fR characters are replaced by \f(CW\*(C`\e$\*(C'\fR and | |
240 | \&\f(CW\*(C`\e@\*(C'\fR, respectively. This isn't foolproof, of course, so don't embed \f(CW\*(C`\e$\*(C'\fR | |
241 | or \f(CW\*(C`\e@\*(C'\fR in double-quoted strings unless you're willing to deal with the | |
242 | consequences. (The slashes will end up escaped and the \f(CW\*(C`$\*(C'\fR or \f(CW\*(C`@\*(C'\fR will | |
243 | trigger variable interpolation) | |
244 | .SH "GLOSSARY" | |
245 | .IX Header "GLOSSARY" | |
246 | Most \f(CW\*(C`Config\*(C'\fR variables are determined by the \f(CW\*(C`Configure\*(C'\fR script | |
247 | on platforms supported by it (which is most \s-1UNIX\s0 platforms). Some | |
248 | platforms have custom-made \f(CW\*(C`Config\*(C'\fR variables, and may thus not have | |
249 | some of the variables described below, or may have extraneous variables | |
250 | specific to that particular port. See the port specific documentation | |
251 | in such cases. | |

325 | From \fIpatchlevel.U\fR: | |
326 | .Sp | |
327 | The three variables, api_revision, api_version, and | |
328 | api_subversion, specify the version of the oldest perl binary | |
329 | compatible with the present perl. In a full version string | |
330 | such as \fI5.6.1\fR, api_revision is the \f(CW5\fR. | |
331 | Prior to 5.5.640, the format was a floating point number, | |
332 | like 5.00563. | |
333 | .Sp | |
334 | \&\fIperl.c\fR:\fIincpush()\fR and \fIlib/lib.pm\fR will automatically search in | |
335 | \&\fI$sitelib/.\fR. for older directories back to the limit specified | |
336 | by these api_ variables. This is only useful if you have a | |
337 | perl library directory tree structured like the default one. | |
338 | See \f(CW\*(C`INSTALL\*(C'\fR for how this works. The versioned site_perl | |
339 | directory was introduced in 5.005, so that is the lowest | |
340 | possible value. The version list appropriate for the current | |
341 | system is determined in \fIinc_version_list.U\fR. | |
342 | .Sp | |
343 | \&\f(CW\*(C`XXX\*(C'\fR To do: Since compatibility can depend on compile time | |
344 | options (such as bincompat, longlong, etc.) it should | |
345 | (perhaps) be set by Configure, but currently it isn't. | |
346 | Currently, we read a hard-wired value from \fIpatchlevel.h\fR. | |
347 | Perhaps what we ought to do is take the hard-wired value from | |
348 | \&\fIpatchlevel.h\fR but then modify it if the current Configure | |
349 | options warrant. \fIpatchlevel.h\fR then would use an #ifdef guard. | |

5538 | From \fIinstallstyle.U\fR: | |
5539 | .Sp | |
5540 | This variable describes the \f(CW\*(C`style\*(C'\fR of the perl installation. | |
5541 | This is intended to be useful for tools that need to | |
5542 | manipulate entire perl distributions. Perl itself doesn't use | |
5543 | this to find its libraries \*(-- the library directories are | |
5544 | stored directly in \fIConfig.pm\fR. Currently, there are only two | |
5545 | styles: \f(CW\*(C`lib\*(C'\fR and \fIlib/perl5\fR. The default library locations | |
5546 | (e.g. privlib, sitelib) are either \fI$prefix/lib\fR or | |
5547 | \&\fI$prefix/lib/perl5\fR. The former is useful if \f(CW$prefix\fR is a | |
5548 | directory dedicated to perl (e.g. \fI/opt/perl\fR), while the latter | |
5549 | is useful if \f(CW$prefix\fR is shared by many packages, e.g. if | |
5550 | \&\f(CW$prefix\fR=\fI/usr/local\fR. | |
5551 | .Sp | |
5552 | Unfortunately, while this \f(CW\*(C`style\*(C'\fR variable is used to set | |
5553 | defaults for all three directory hierarchies (core, vendor, and | |
5554 | site), there is no guarantee that the same style is actually | |
5555 | appropriate for all those directories. For example, \f(CW$prefix\fR | |
5556 | might be \fI/opt/perl\fR, but \f(CW$siteprefix\fR might be \fI/usr/local\fR. | |
5557 | (Perhaps, in retrospect, the \f(CW\*(C`lib\*(C'\fR style should never have been | |
5558 | supported, but it did seem like a nice idea at the time.) | |
5559 | .Sp | |
5560 | The situation is even less clear for tools such as MakeMaker | |
5561 | that can be used to install additional modules into | |
5562 | non-standard places. For example, if a user intends to install | |
5563 | a module into a private directory (perhaps by setting \f(CW\*(C`PREFIX\*(C'\fR on | |
5564 | the \fIMakefile.PL\fR command line), then there is no reason to | |
5565 | assume that the Configure-time \f(CW$installstyle\fR setting will be | |
5566 | relevant for that \f(CW\*(C`PREFIX\*(C'\fR. | |
5567 | .Sp | |
5568 | This may later be extended to include other information, so | |
5569 | be careful with pattern-matching on the results. | |
5570 | .Sp | |
5571 | For compatibility with \fIperl5.005\fR and earlier, the default | |
5572 | setting is based on whether or not \f(CW$prefix\fR contains the string | |

8207 | From \fIversiononly.U\fR: | |
8208 | .Sp | |
8209 | If set, this symbol indicates that only the version-specific | |
8210 | components of a perl installation should be installed. | |
8211 | This may be useful for making a test installation of a new | |
8212 | version without disturbing the existing installation. | |
8213 | Setting versiononly is equivalent to setting installperl's \-v option. | |
8214 | In particular, the non-versioned scripts and programs such as | |
8215 | a2p, c2ph, h2xs, pod2*, and perldoc are not installed | |
8216 | (see \f(CW\*(C`INSTALL\*(C'\fR for a more complete list). Nor are the man | |
8217 | pages installed. | |
8218 | Usually, this is undef. | |

8228 | .IX Item "voidflags" | |
8229 | From \fIvoidflags.U\fR: | |
8230 | .Sp | |
8231 | This variable contains the eventual value of the \f(CW\*(C`VOIDFLAGS\*(C'\fR symbol, | |
8232 | which indicates how much support of the void type is given by this | |
8233 | compiler. See \f(CW\*(C`VOIDFLAGS\*(C'\fR for more info. | |

8239 | From \fIlibpth.U\fR: | |
8240 | .Sp | |
8241 | This variable holds extra path (space\-separated) used to find | |
8242 | libraries on this platform, for example \f(CW\*(C`CPU\*(C'\fR\-specific libraries | |
8243 | (on multi\-\f(CW\*(C`CPU\*(C'\fR platforms) may be listed here. | |

8248 | .IX Item "yacc" | |
8249 | From \fIyacc.U\fR: | |
8250 | .Sp | |
8251 | This variable holds the name of the compiler compiler we | |
8252 | want to use in the Makefile. It can be yacc, byacc, or bison \-y. | |
8253 | .ie n .IP """yaccflags""" 4 | |
8254 | .el .IP "\f(CWyaccflags\fR" 4 | |
8255 | .IX Item "yaccflags" | |
8256 | From \fIyacc.U\fR: | |
8257 | .Sp | |
8258 | This variable contains any additional yacc flags desired by the | |
8259 | user. It is up to the Makefile to use this. | |
8260 | .Sh "z" | |
8261 | .IX Subsection "z" | |

8271 | .IX Item "zip" | |
8272 | From \fILoc.U\fR: | |
8273 | .Sp | |
8274 | This variable is used internally by Configure to determine the | |
8275 | full pathname (if any) of the zip program. After Configure runs, | |
8276 | the value is reset to a plain \f(CW\*(C`zip\*(C'\fR and is not useful. | |
8277 | .SH "NOTE" | |
8278 | .IX Header "NOTE" | |
8279 | This module contains a good example of how to use tie to implement a | |
8280 | cache and an example of how to make a tied variable readonly to those | |
8281 | outside of it. |
