#pod
#pod =head1 DESCRIPTION
#pod
#pod This is a L<Dist::Zilla> plugin that runs at the L<gather files|Dist::Zilla::Role::FileGatherer> stage,
#pod providing a test file (configurable, defaulting to F<t/00-compile.t>).
#pod
#pod This test will find all modules and scripts in your distribution, and try to
#pod compile them one by one. This means it's a bit slower than loading them
#pod all at once, but it will catch more errors.
#pod
#pod The generated test is guaranteed to only depend on modules that are available
#pod in core. Most options only require perl 5.6.2; the C<bail_out_on_fail> option
#pod requires the version of L<Test::More> that shipped with perl 5.12 (but the
#pod test still runs on perl 5.6).
#pod
#pod This plugin accepts the following options:
#pod
#pod =head1 CONFIGURATION OPTIONS
#pod
#pod =head2 C<filename>
#pod
#pod The name of the generated file. Defaults to F<t/00-compile.t>
#pod
#pod =head2 C<phase>
#pod
#pod The phase for which to register prerequisites. Defaults
#pod to C<test>. Setting this to a false value will disable prerequisite
#pod registration.
#pod
#pod =head2 C<skip>
#pod
#pod A regex to skip compile test for B<modules> matching it. The
#pod match is done against the module name (C<Foo::Bar>), not the file path
#pod (F<lib/Foo/Bar.pm>). This option can be repeated to specify multiple regexes.
#pod
#pod =head2 C<file>
#pod
#pod A filename to also test, in addition to any files found
#pod earlier. It will be tested as a module if it ends with C<.pm> or C<.PM>,
#pod and as a script otherwise.
#pod Module filenames should be relative to F<lib>; others should be relative to
#pod the base of the repository.
#pod This option can be repeated to specify multiple additional files.
#pod
#pod =head2 C<fake_home>
#pod
#pod =for stopwords cpantesters
#pod
#pod A boolean to indicate whether to fake C<< $ENV{HOME} >>.
#pod This may be needed if your module unilaterally creates stuff in the user's home directory:
#pod indeed, some cpantesters will smoke test your distribution with a read-only home
#pod directory. Defaults to false.
#pod
#pod =head2 C<needs_display>
#pod
#pod A boolean to indicate whether to skip the compile test
#pod on non-Win32 systems when C<< $ENV{DISPLAY} >> is not set. Defaults to false.
#pod
#pod =head2 C<fail_on_warning>
#pod
#pod A string to indicate when to add a test for
#pod warnings during compilation checks. Possible values are:
#pod
#pod =over 4
#pod
#pod =item * C<none>: do not test for warnings
#pod
#pod =item * C<author>: test for warnings only when AUTHOR_TESTING is set
#pod (default, and recommended)
#pod
#pod =item * C<all>: always test for warnings (not recommended, as this can prevent
#pod installation of modules when upstream dependencies exhibit warnings in a new
#pod Perl release)
#pod
#pod =back
#pod
#pod =head2 C<bail_out_on_fail>
#pod
#pod A boolean to indicate whether the test will BAIL_OUT
#pod of all subsequent tests when compilation failures are encountered. Defaults to false.
#pod
#pod =head2 C<module_finder>
#pod
#pod =for stopwords FileFinder
#pod
#pod This is the name of a L<FileFinder|Dist::Zilla::Role::FileFinder> for finding
#pod modules to check. The default value is C<:InstallModules>; this option can be
#pod used more than once. F<.pod> files are always skipped.
#pod
#pod Other predefined finders are listed in
#pod L<Dist::Zilla::Role::FileFinderUser/default_finders>.
#pod You can define your own with the
#pod L<[FileFinder::ByName]|Dist::Zilla::Plugin::FileFinder::ByName> and
#pod L<[FileFinder::Filter]|Dist::Zilla::Plugin::FileFinder::Filter> plugins.
#pod
#pod =head2 C<script_finder>
#pod
#pod =for stopwords executables
#pod
#pod Just like C<module_finder>, but for finding scripts. The default value is
#pod C<:PerlExecFiles> (when available; otherwise C<:ExecFiles>)
#pod -- see also L<Dist::Zilla::Plugin::ExecDir>, to make sure these
#pod files are properly marked as executables for the installer.
#pod
#pod =head2 C<xt_mode>
#pod
#pod When true, the default C<filename> becomes F<xt/author/00-compile.t> and the
#pod default C<dependency> phase becomes C<develop>.
#pod
#pod =head2 C<switch>
#pod
#pod Use this option to pass a command-line switch (e.g. C<-d:Confess>, C<-M-warnings=numeric>) to the command that
#pod tests the module or script. Can be used more than once. See L<perlrun> for more on constructing these switches.
#pod
#pod =head1 RUNTIME ENVIRONMENT OPTIONS
#pod
#pod If the environment variable C<$PERL_COMPILE_TEST_DEBUG> is set to a true option when the test is run, the command
#pod to test each file will be printed as a C<diag>.
