=head1 Description
A class that coordinates the various stages of a raku distribution installation workflow based on
various configuration parameters.
Additionally it provides slightly higher level facilities for fetching, extracting, etc, than the
e.g. C<Zef::Fetch>, C<Zef::Extract>, etc modules it uses underneath. For example C<Zef::Client.fetch>
may run an extraction step unlike C<Zef::Fetch.fetch>, since the former is in the context of a distribution
(i.e. we want the distribution at the specific commit/tag, not the HEAD immediately after fetching).
=head1 Methods
=head2 method find-candidates
method find-candidates(*@identities ($, *@) --> Array[Candidate])
Searches all repositories via C<Zef::Repository> and returns a matching C<Candidate> / distribution for each supplied
identity. Generally this is used to find the top level distributions requested, such as C<Foo> in C<zef install Foo>.
=head2 method find-candidates
method find-prereq-candidates(Bool :$skip-installed = True, *@candis ($, *@) --> Array[Candidate])
Similar to C<method find-candidates> but returns matching a matching C<Candidate> for each dependency of the supplied
identities. Generally this is used to recursively discover and determine the dependencies of the identities requested.
If C<$skip-installed> is set to C<False> it will potentially install a newer version of an already installed matching
dependency (without uninstalling the previous version). It also skips any identity matching of C<@.ignore>, which allows
getting past an unresolvable dependency ala `zef install Inline::Perl5 --ignore="perl"`.
Returns an C<Array> of C<Candidate> that fulfill the dependency requirements of C<@identities>.
=head2 method search
method search(*@identities ($, *@), *%fields, Bool :$strict = False --> Array[Candidate])
Resolves each identity in C<@identities> to all of its matching C<Candidates> from all backends via C<Zef::Repository> (with C<$max-results>
applying to each individual backend). If C<$strict> is C<False> then it will consider partial matches on module short-names (i.e. 'zef search HTTP'
will get results for e.g. C<HTTP::UserAgent>).
=head2 method fetch
method fetch(*@candidates ($, *@) --> Array[Candidate])
Fetches a distribution from some location, and unpacks/extracts it to a temporary location to be used be cached, tested,
installed, etc. It effective combines the functionality of C<Zef::Fetch.fetch> and C<Zef::Extract.extract> into a single
method as there isn't yet a useful reason to have workflows that work with compressed archives/packages. Fetches up to
C<$.fetch-degree> different C<@candidates> in parallel.
Anytime a distribution is fetched it will call C<.store(@distributions)> on any C<Zef::Repository> that supports it (usually
just C<Zef::Repository::LocalCache>).
File are saved to the C<TempDir> setting in C<resources/config.json>, and extracted to the C<$.cache> directory (the C<StoreDir>
setting in C<resources/config.json>).
Returns an C<Array> of C<Candidate> containing the successfully fetched results.
=head2 method build
method build(*@candidates ($, *@) --> Array[Candidate])
Runs the build process on each C<@candidates> that the backends for C<Zef::Build> know how to process. Builds up to C<$.build-degree>
different C<@candidates> in parallel.
Returns an C<Array> of C<Candidate> with each C<.build-results> set appropriately.
=head2 method test
method test(*@candidates ($, *@) --> Array[Candidate])
Runs the test process on each C<@candidates> via the backends of C<Zef::Test>. Tests up to C<$.test-degree> different
C<@candidates> in parallel.
Returns an C<Array> of C<Candidate> with each C<.test-results> set appropriately.
=head2 method uninstall
method uninstall(CompUnit::Repository :@from!, *@identities --> Array[Candidate])
Searches each C<CompUnit::Repository> in C<@from> for each C<@identities> and uninstalls any matching distributions.
For instance uninstalling C<zef> could potentially uninstall multiple versions, whereas uninstall C<zef:ver("0.9.4")> would
only uninstall that specific version.
Returns an C<Array> containing each uninstalled C<Candidate>.
=head2 method install
method install(:@curs, *@candidates ($, *@) --> Array[Candidate])
Install a C<Candidate> containing a C<Distribution> to each C<CompUnit::Repository> in C<@curs>.
Returns an C<Array> containing each successfully installed C<Candidate>.
=head2 method make-install
method make-install(CompUnit::Repository :@to!, Bool :$fetch = True, Bool :$build = True, Bool :$test = True, Bool :$dry, Bool :$serial, *@candidates ($, *@), *%_)
The 'do everything but resolve dependencies' method. You essentially figure out all the C<Candidate> you need to install
(dependencies, etc) and pass them to this method. Its similar to C<method install> except it also handles calling C<method fetch>
(if C<$fetch> is C<True>), C<method build> (if C<$build> is C<True>), and C<method test> (if <$test> is C<True>). If C<$dry> is
C<True> then the final step of calling C<method install> (which moves the modules to where C<raku> will see them) will be skipped.
If <$serial> is C<True> then each C<Candidate> will be installed after it passes its own tests (instead of the default behavior of
only installing if all C<Candidate>, including dependencies, pass their tests).
=head2 method list-rev-depends
method list-rev-depends($identity, Bool :$indirect --> Array[Candidate])
Return an C<Array> of C<Candidate> of all distribution that directly depend on C<$identity>. If C<$indirect> is C<True> then it
additionally returns distributions that indirectly / transitively depend on C<$identity>
=head2 method list-available
method list-available(*@recommendation-manager-names --> Array[Candidate])
Returns an C<Array> of C<Candidate> for every distribution from every repository / recommendation-manager with a name (as
set in C<resources/config.json>) matching any of those in C<@recommendation-manager-names> (or all repositories if no names
are supplied). Note some non-standard repositories may not support listing all available distributions.
=head2 method list-installed
method list-installed(*@curis --> Array[Candidate])
Returns an C<Array> of C<Candidate> for each Raku distribution installed to each C<CompUnit::Repository::Installation> C<@curis>
(or all known C<CompUnit::Repository::Installation> if no C<@curis> are supplied).
=head2 method list-leaves
method list-leaves(--> Array[Candidate])
Returns an C<Array> of C<Candidate> for each installed distributions that nothing else appears to depend on.
=head2 method list-dependencies
method list-dependencies(*@candis --> Array[DependencySpecification])
Returns an C<Array> of C<Zef::Distribution::DependencySpecification> and // or C<Zef::Distribution::DependencySpecification::Any>
for each C<@candis> distributions various dependency requirements.
If C<$.depends> is set to C<False> then runtime dependencies will be ignored.
If C<$.test-depends> is set to C<False> then test dependencies will be ignored.
If C<$.build-depends> is set to C<False> then build dependencies will be ignored.
=head2 method resolve
method resolve($spec, CompUnit::Repository :@at --> Array[Candidate])
Returns the best matching distributions from installed sources for the given C<$spec>, in preferred order (highest api
version and highest version) from each C<CompUnit::Repository> in C<@at> (or all known C<CompUnit::Repository> if C<@at>
is not set). C<$spec> should be either a C<Zef::Distribution::DependencySpecification> or C<Zef::Distribution::DependencySpecification::Any>.
=head2 method is-installed
multi method is-installed(Str $spec, |c --> Bool:D)
multi method is-installed(Zef::Distribution::DependencySpecification::Any $spec, |c --> Bool:D)
multi method is-installed(Zef::Distribution::DependencySpecification $spec, |c --> Bool:D)
Returns C<True> if the requested C<$spec> is installed. The logic it uses to decide if something is installed is based on
the C<$spec.from-matcher>: C<foo:from<bin>> will search C<$PATH> for C<foo>, C<foo:from<native>> will check if C<NativeCall>
can see an e.g. C<libfoo.so> or C<foo.dll>, and everything else will be looked up as a C<foo> raku module.
=head2 method sort-candidates
method sort-candidates(@candis --> Array[Candidate])
Does a topological sort of C<@candis> based on their various dependency fields and C<$.depends>/C<$.test-depends>/C<$.build-depends>.
