38=head1 DESCRIPTION
39
40The functions exported by this module deal with runtime handling of
41Perl modules, which are normally handled at compile time. This module
42avoids using any other modules, so that it can be used in low-level
43infrastructure.
44
45The parts of this module that work with module names apply the same
46syntax that is used for barewords in Perl source. In principle this
47syntax can vary between versions of Perl, and this module applies the
48syntax of the Perl on which it is running. In practice the usable syntax
49hasn't changed yet, but there's a good chance of it changing in Perl 5.18.
50
51The functions of this module whose purpose is to load modules include
52workarounds for three old Perl core bugs regarding C<require>. These
53workarounds are applied on any Perl version where the bugs exist, except
54for a case where one of the bugs cannot be adequately worked around in
55pure Perl.
56
57=head2 Module name syntax
58
59The usable module name syntax has not changed from Perl 5.000 up to
60Perl 5.15.7. The syntax is composed entirely of ASCII characters.
61From Perl 5.6 onwards there has been some attempt to allow the use of
62non-ASCII Unicode characters in Perl source, but it was fundamentally
63broken (like the entirety of Perl 5.6's Unicode handling) and remained
64pretty much entirely unusable until it got some attention in the Perl
655.15 series. Although Unicode is now consistently accepted by the
66parser in some places, it remains broken for module names. Furthermore,
67there has not yet been any work on how to map Unicode module names into
68filenames, so in that respect also Unicode module names are unusable.
69This may finally be addressed in the Perl 5.17 series.
70
71The module name syntax is, precisely: the string must consist of one or
72more segments separated by C<::>; each segment must consist of one or more
73identifier characters (ASCII alphanumerics plus "_"); the first character
74of the string must not be a digit. Thus "C<IO::File>", "C<warnings>",
75and "C<foo::123::x_0>" are all valid module names, whereas "C<IO::>"
76and "C<1foo::bar>" are not. C<'> separators are not permitted by this
77module, though they remain usable in Perl source, being translated to
78C<::> in the parser.
79
80=head2 Core bugs worked around
81
82The first bug worked around is core bug [perl #68590], which causes
83lexical state in one file to leak into another that is C<require>d/C<use>d
84from it. This bug is present from Perl 5.6 up to Perl 5.10, and is
85fixed in Perl 5.11.0. From Perl 5.9.4 up to Perl 5.10.0 no satisfactory
86workaround is possible in pure Perl. The workaround means that modules
87loaded via this module don't suffer this pollution of their lexical
88state. Modules loaded in other ways, or via this module on the Perl
89versions where the pure Perl workaround is impossible, remain vulnerable.
90The module L<Lexical::SealRequireHints> provides a complete workaround
91for this bug.
92
93The second bug worked around causes some kinds of failure in module
94loading, principally compilation errors in the loaded module, to be
95recorded in C<%INC> as if they were successful, so later attempts to load
96the same module immediately indicate success. This bug is present up
97to Perl 5.8.9, and is fixed in Perl 5.9.0. The workaround means that a
98compilation error in a module loaded via this module won't be cached as
99a success. Modules loaded in other ways remain liable to produce bogus
100C<%INC> entries, and if a bogus entry exists then it will mislead this
101module if it is used to re-attempt loading.
102
103The third bug worked around causes the wrong context to be seen at
104file scope of a loaded module, if C<require> is invoked in a location
105that inherits context from a higher scope. This bug is present up to
106Perl 5.11.2, and is fixed in Perl 5.11.3. The workaround means that
107a module loaded via this module will always see the correct context.
108Modules loaded in other ways remain vulnerable.

251The I<NAME> is a string, which should be a valid module name (one or

253C<die>s.
254
255The notional filename for the named module is generated and returned.
256This filename is always in Unix style, with C</> directory separators
257and a C<.pm> suffix. This kind of filename can be used as an argument to
258C<require>, and is the key that appears in C<%INC> to identify a module,
259regardless of actual local filename syntax.

271
272This is essentially the bareword form of C<require>, in runtime form.
273The I<NAME> is a string, which should be a valid module name (one or
274more C<::>-separated segments). If it is not a valid name, the function
275C<die>s.
276
277The module specified by I<NAME> is loaded, if it hasn't been already,
278in the manner of the bareword form of C<require>. That means that a
279search through C<@INC> is performed, and a byte-compiled form of the
280module will be used if available.
281
282The return value is as for C<require>. That is, it is the value returned
283by the module itself if the module is loaded anew, or C<1> if the module
284was already loaded.

327=item use_module(NAME[, VERSION])
328
329This is essentially C<use> in runtime form, but without the importing
330feature (which is fundamentally a compile-time thing). The I<NAME> is
331handled just like in C<require_module> above: it must be a module name,
332and the named module is loaded as if by the bareword form of C<require>.
333
334If a I<VERSION> is specified, the C<VERSION> method of the loaded module is
335called with the specified I<VERSION> as an argument. This normally serves to
336ensure that the version loaded is at least the version required. This is
337the same functionality provided by the I<VERSION> parameter of C<use>.
338
339On success, the name of the module is returned. This is unlike
340L</require_module>, and is done so that the entire call to L</use_module>
341can be used as a class name to call a constructor, as in the example in
342the synopsis.

357This is an analogue of L</use_module> for the situation where there is
358uncertainty as to whether a package/class is defined in its own module
359or by some other means. It attempts to arrange for the named package to
360be available, either by loading a module or by doing nothing and hoping.
361
362An attempt is made to load the named module (as if by the bareword form
363of C<require>). If the module cannot be found then it is assumed that
364the package was actually already loaded by other means, and no error
365is signalled. That's the optimistic bit.
366
367This is mostly the same operation that is performed by the L<base> pragma
368to ensure that the specified base classes are available. The behaviour
369of L<base> was simplified in version 2.18, and this function changed
370to match.
371
372If a I<VERSION> is specified, the C<VERSION> method of the loaded package is
373called with the specified I<VERSION> as an argument. This normally serves
374to ensure that the version loaded is at least the version required.
375On success, the name of the package is returned. These aspects of the
376function work just like L</use_module>.

400See below for what that entails. Whether a I<PREFIX> is supplied affects
401the validity of I<SPEC>, but the exact value of the prefix is unimportant,
402so this function treats I<PREFIX> as a truth value.

436
437This function is intended to make it more convenient for a user to specify
438a Perl module name at runtime. Users have greater need for abbreviations
439and context-sensitivity than programmers, and Perl module names get a
440little unwieldy. I<SPEC> is what the user specifies, and this function
441translates it into a module name in standard form, which it returns.
442
443I<SPEC> has syntax approximately that of a standard module name: it
444should consist of one or more name segments, each of which consists
445of one or more identifier characters. However, C</> is permitted as a
446separator, in addition to the standard C<::>. The two separators are
447entirely interchangeable.
448
449Additionally, if I<PREFIX> is not C<undef> then it must be a module
450name in standard form, and it is prefixed to the user-specified name.
451The user can inhibit the prefix addition by starting I<SPEC> with a
452separator (either C</> or C<::>).
