   More CLI
       install [*@identities]

       Note: The install process does not install anything until all phases have completed. So,
       if the user requested to "install A", and A required module B: both would be downloaded,
       potentially built, tested, and installed -- but only if both passed all their tests. For
       example: if module A failed its tests, then module B would not be installed (even if it
       passed its own tests) unless forced.

       [@identities] can take the form of a file path (starting with . or /), URLs, paths, or
       identities:

           # IDENTITY
           zef install CSV::Parser
           zef install "CSV::Parser:auth<tony-o>:ver<0.1.2>"
           zef install "CSV::Parser:ver<0.1.2>"

           # PATH
           zef install ./Perl6-Net--HTTP

           # URL
           zef -v install git://github.com/ugexe/zef.git
           zef -v install https://github.com/ugexe/zef/archive/master.tar.gz
           zef -v install https://github.com/ugexe/zef.git@v0.1.22

       A request may contain any number and combination of these. Paths and URLs will be resolved
       first so they are available to fulfill any dependencies of other requested identities.

       uninstall [*@identities]

       Uninstall the specified distributions

       Note: Requires a bleeding edge rakudo (not available in 6.c)

       update

       Update the package indexes for all "Repository" backends

       Note: Some "Repository" backends, like the default Ecosystems, have an "auto-update"
       option in "resources/config.json" that can be enabled. This should be the number of hours
       until it should auto update based on the file system last modified time of the ecosystem
       json file location.

       upgrade [*@identities] BETA

       Upgrade specified identities. If no identities are provided, zef attempts to upgrade all
       installed distributions.

       search [$identity]

       How these are handled depends on the "Repository" engine used, which by default is
       "Zef::Repository::Ecosystems>p6c<"

           # Extra details (eg, list dependencies and which ones are installed)
           -v

       list [*@from]

       List known available distributions

           $ zef --installed list
           ===> Found via /home/nickl/.rakubrew/moar-master/install/share/perl6/site
           CSV::Parser:ver<0.1.2>:auth<github:tony-o>

           ===> Found via /home/nickl/.rakubrew/moar-master/install/share/perl6
           CORE:ver<6.c>:auth<perl>

       Note that not every Repository may provide such a list, and such lists may only be a
       subset. For example: We may not be able to get a list of every distribution on cpan, but
       we *can* get the $x most recent additions (we use 100 for now).

       [@from] allows you to show results from specific repositories only:

           zef --installed list perl   # Only list modules installed by rakudo itself

           zef list cpan               # Only show available modules from the repository
           zef list p6c                # with a name field matching the arguments to `list`
           zef list cached             # (be sure the repository is enabled in config)

       Otherwise results from all enabled repositories will be returned.

       Options

           # Only list installed distributions
           --installed

           # Additionally list the modules of discovered distributions
           -v

       depends [$identity]

       List direct and transitive dependencies to the first successful build graph for $identity

           Cro::Core:ver<0.7>
           IO::Socket::Async::SSL:ver<0.3>
           OpenSSL:ver<0.1.14>:auth<github:sergot>

       rdepends [$identity]

       List available distributions that directly depend on $identity

           $ zef rdepends Net::HTTP
           Minecraft-Tools:ver<0.1.0>
           LendingClub:ver<0.1.0>

       fetch [*@identities]

       Fetches candidates for given identities

       test [*@paths]

       Run tests on each distribution located at [@paths]

       build [*@paths]

       Run the Build.pm file located in the given [@paths]

       If you want to create a build hook, put the following dependency-free boilerplate in a
       file named "Build.pm" at the root of your distribution:

           class Build {
               method build($dist-path) {
                   # do build stuff to your module
                   # which is located at $dist-path
               }
           }

       Set the env variable ZEF_BUILDPM_DEBUG=1 or use the --debug flag for additional debugging
       information.

       Note: In the future, a more appropriate hooking solution will replace this.

       look [$identity]

       Fetches the requested distribution and any dependencies (if requested), changes the
       directory to that of the fetched distribution, and then stops program execution. This
       allows you modify or look at the source code before manually continuing the install via
       "zef install ."

       Note that the path to any dependencies that needed to be fetched will be set in env at
       PERL6LIB, so you should be able to run any build scripts, tests, or complete a manual
       install without having to specify their locations.

Global Configuration

       Finding the configuration file

       You can always see the configuration file that will be used by running:

           $ zef --help

       In most cases the default configuration combined with command line options should be
       enough for most users.

       If you are most users (e.g. not: power users, packagers, zef plugin developers) you
       hopefully don't care about this section!

       How the configuration file is chosen

       The configuration file will be chosen at runtime from one of two (technically four)
       locations, and one can affect the others (this is not really a design decision and
       suggestions and PRs are welcome).

       First, and the most precise way, is to specify the config file by passing
       "--config-path="..."" to any zef command.

       Second, third, and fourth we look at the path pointed to by "%?RESOURCES<config.json>".
       This will point to "$zef-dir/resources/config.json", where "$zef-dir" will be either:

       ·   The prefix of a common configuration directory, such as $XDG_CONFIG_HOME  or
           "$HOME/.config".

       ·   The prefix of a rakudo installation location - This is the case if the modules loaded
           for bin/zef come from an installation CompUnit::Repository.

       ·   The current working directory $*CWD - This is the case when modules loaded for bin/zef
           come from a non-installation CompUnit::Repository (such as "-I $dist-path").

           To understand how this is chosen, consider:

               # Modules not loaded from an ::Installation,
               # so %?RESOURCES is $*CWD/resources
               $ perl6 -I. bin/zef --help
               ...
               CONFIGURATION /home/user/perl6/zef/resources/config.json
               ...

               # Installed zef script loads modules from an ::Installation,
               # so %?RESOURCES is $perl6-share-dir/site/resources
               $ zef --help
               ...
               CONFIGURATION /home/user/perl6/install/share/perl6/site/resources/EE5DBAABF07682ECBE72BEE98E6B95E5D08675DE.json
               ...

       This config is loaded, but it is not yet the chosen config! We check that temporary
       config's "%config<RootDir>" for valid json in a file named "config.json" (i.e.
       "%config<RootDir>/config.json"). This can be confusing (so it may go away or be refined -
       PRs welcome) but for most cases it just means "$*HOME/.zef/config.json" will override an
       installed zef configuration file.

       To summarize:

       ·   You can edit the "resources/config.json" file before you install zef.

           When you "perl6 -I. bin/zef install ." that configuration file be be used to install
           zef and will also be installed with zef such that it will be the default.

       ·   You can create a "%config<RootDir>/config.json" file.

           Where "%config<RootDir>" comes from the previously mentioned
           "%?RESOURCES<config.json>"'s "RootDir" field ("$*HOME/.zef" in most cases), to allow
           overriding zef config behavior on a per user basis (allows setting different
           "--install-to" targets for, say, a root user and a regular user). Since this new
           config file could have a different "RootDir" than the default config (used to find the
           new one in the first place) this behavior may be changed in the future to be less
           confusing.

       ·   You can override both of the previous entries by passing "zef --config-path="$path"
           <any command>"

       Configuration fields

       Basic Settings

       ·   RootDir - Where zef will look for a custom config.json file

       ·   TempDir - A staging area for items that have been fetched and need to be
           extracted/moved

       ·   StoreDir - Where zef caches distributions, package lists, etc after they've been
           fetched and extracted

       ·   DefaultCUR - This sets the default value for "--install-to="..."". The default value
           of "auto" means it will first try installing to rakudo's installation prefix, and if
           its not writable by the current user it will install to "$*HOME/.perl6". These
           directories are not chosen by zef - they are actually represented by the magic strings
           "site" and "home" (which, like "auto", are valid values despite not being paths along
           with "vendor" and "perl")

       Phases / Plugins Settings

       These consist of an array of hashes that describe how to instantiate some class that
       fulfills the appropriate interface from Zef.pm ("Repository" "Fetcher" "Extractor"
       "Builder" "Tester")

       The descriptions follow this format:

           {
               "short-name" : "p6c",
               "enabled" : 1,
               "module" : "Zef::Repository::Ecosystems",
               "options" : { }
           }

       and are instantiated via

           ::($hash<module>).new(|($hash<options>)

       ·   short-name - This adds an enable and disable flag by the same name to the CLI (e.g.
           "--p6c" and "--/p6c") and is used when referencing which object took some action.

       ·   enabled - Set to 0 to skip over the object during consideration (it will never be
           loaded). If omitted or if the value is non 0 then it will be enabled for use.

       ·   module - The name of the class to instantiate. While it doesn't technically have to be
           a module it does need to be a known namespace to "require".

       ·   options - These are passed to the objects "new" method and may not be consistent
           between modules as they are free to implement their own requirements.

       See the configuration file in resources/config.json
       <https://github.com/ugexe/zef/blob/master/resources/config.json> for a little more
       information on how plugins are invoked.

       You can see debug output related to chosing and loading plugins by setting the env
       variable ZEF_PLUGIN_DEBUG=1

FAQ

       CPAN?

       CPAN is now used as a default (alongside the familiar p6c "ecosystem").

           # Explicitly enable cpan (now defaults to the same as `zef search zef`)
           $ zef --cpan search Inline::Perl5

       Proxy support?

       All the default fetching plugins have proxy support, but you'll need to refer to the
       backend program's (wget, curl, git, etc) docs. You may need to set an ENV variable, or you
       may need to add a command line option for that specific plugin in resources/config.json

       Custom installation locations?

       Pass a path to the -to / --install-to option and prefix the path with "inst#" (unless you
       know what you're doing)

           $ zef -to="inst#/home/perl6/custom" install Text::Table::Simple
           ===> Searching for: Text::Table::Simple
           ===> Testing: Text::Table::Simple:ver<0.0.3>:auth<github:ugexe>
           ===> Testing [OK] for Text::Table::Simple:ver<0.0.3>:auth<github:ugexe>
           ===> Installing: Text::Table::Simple:ver<0.0.3>:auth<github:ugexe>

       To make the custom location discoverable:

           # Set the PERL6LIB env:
           $ PERL6LIB="inst#/home/perl6/custom" perl6 -e "use Text::Table::Simple; say 'ok'"
           ok

           # or simply include it as needed
           $ perl6 -Iinst#/home/perl6/custom -e "use Text::Table::Simple; say 'ok'"
           ok

       Test reporting?

       This feature can be enabled by passing `--p6ctesters` (and having "Net::HTTP" installed)
       or `--cpantesters` (and having "Zef::CPANReporter" installed)
