Zef is a package manager dedicated for Raku language.
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.

ENV Options
# Number of simultaneous distributions/jobs to process for the corresponding phases (see: --[phase]-degree options) ZEF_FETCH_DEGREE=5 ZEF_TEST_DEGREE=1 # Set the timeout for corresponding phases (see: --[phase]-timeout options) ZEF_FETCH_TIMEOUT=600 ZEF_EXTRACT_TIMEOUT=3600 ZEF_BUILD_TIMEOUT=3600 ZEF_TEST_TIMEOUT=3600 ZEF_INSTALL_TIMEOUT=3600 # Path to config file (see: --config-path option) ZEF_CONFIG_PATH=$PWD/resources/config.json
Uninstall the specified distributions
Note: Requires a bleeding edge rakudo (not available in 6.c)
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 specified identities. If no identities are provided, zef attempts to upgrade all installed distributions.
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 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
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>
List available distributions that directly depend on $identity
$ zef rdepends Net::HTTP Minecraft-Tools:ver<0.1.0> LendingClub:ver<0.1.0>
Fetches candidates for given identities
Run tests on each distribution located at [@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.
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.

Deletes all paths in the specific configuration directory
Deletes all paths that are rooted in the prefix of the matching CompUnit::Repository name
# uninstall all modules $ zef nuke site home
You can control the logging level using the following flags:
# More/less detailed output --error, --warn, --info (default), --verbose (-v), --debug
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!
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:
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 $*HOME/.zef/config.json will override an installed zef configuration file.
To summarize:
When you raku -I. bin/zef install . that configuration file be be used to install zef and will also be installed with zef such that it will be the default.
Where %config<RootDir> comes from the previously mentioned %?RESOURCES<config.json>’s RootDir field ($*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.
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>)
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
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
Pass a path to the -to / –install-to option and prefix the path with inst# (unless you know what you’re doing)
