DESCRIPTION
Zef is a package manager dedicated for Raku language.
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 https://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<

Options
# Extra details (eg, list dependencies and which ones are installed)
-v
list [*@from]
List known available distributions
$ zef --installed list
===> Found via /home/foo/.rakubrew/moar-master/install/share/perl6/site
CSV::Parser:ver<0.1.2>:auth<github:tony-o>
Zef:auth<github:ugexe>
===> Found via /home/foo/.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
$ zef depends Cro::SSL
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
RAKULIB, so you should be able to run any build scripts, tests, or complete a manual
install without having to specify their locations.
browse $identity [bugtracker | homepage | source]
Options
# disables launching a browser window (just shows url)
--/open
Output the url and launch a browser to open it.
# also opens browser
$ zef browse Net::HTTP bugtracker
https://github.com/ugexe/Perl6-Net--HTTP/issues
# only outputs the url
$ zef browse Net::HTTP bugtracker --/open

locate [$identity, $name-path, $sha1-id]
Options
# The argument is a sha1-id (otherwise assumed to be an identity or name-path)
--sha1
Lookup a locally installed module by $identity, $name-path, or $sha1-id
$ zef --sha1 locate A9948E7371E0EB9AFDF1EEEB07B52A1B75537C31

--error, --warn, --info (default), --verbose (-v), --debug
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
$ raku -I. bin/zef --help
...
CONFIGURATION /home/user/raku/zef/resources/config.json
...
# Installed zef script loads modules from an ::Installation,
# so %?RESOURCES is $raku-share-dir/site/resources
$ zef --help
...
CONFIGURATION /home/user/raku/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 $*HOME/.zef/config.json will
override an installed zef configuration file.
To summarize:
• You can edit the resources/config.json file before you install zef.
When you raku -I. bin/zef install . that configuration file be be used to install zef
and will also be installed with zef such that it will be the default.
• You can create a %config<RootDir>/config.json file.
Where %config<RootDir> comes from the previously mentioned %?RESOURCES<config.json>’s
RootDir field ($*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 $*HOME/.raku. These directories are not
chosen by zef - they are actually represented by the magic strings site and home (which,
like auto, are valid values despite not being paths along with vendor and perl)
Phases / Plugins Settings
These consist of an array of hashes that describe how to instantiate some class that
fulfills the appropriate interface from Zef.pm (Repository Fetcher Extractor Builder
Tester Reporter)
The descriptions follow this format:
{
"short-name" : "p6c",
"enabled" : 1,
"module" : "Zef::Repository::Ecosystems",
"options" : { }
}
and are instantiated via
::($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
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/raku/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 RAKULIB env:
$ RAKULIB="inst#/home/raku/custom" raku -e "use Text::Table::Simple; say 'ok'"
ok
# or simply include it as needed
$ raku -Iinst#/home/raku/custom -e "use Text::Table::Simple; say 'ok'"
