## 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:ver<0.1.2>"

    zef install "CSV::Parser:ver<0.1.2>"



    # PATH

    zef install ./Raku-Net--HTTP



    # URL

    zef -v install https://github.com/ugexe/zef.git

    zef -v install https://github.com/ugexe/zef/archive/main.tar.gz

    zef -v install https://github.com/ugexe/[email protected]



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



#### **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` and `Zef::Repository::Ecosystems`



    $ zef -v search URI

**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/install/share/perl6/site

    CSV::Parser:ver<0.1.2>:auth

    Zef:auth

    ===> Found via /home/foo/.rakubrew/moar/install/share/perl6

    CORE:ver<6.c>:auth



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 fez               # Only show available modules from the repository

    zef list rea               # with a name field matching the arguments to `list`

    zef list p6c               # (be sure the repository is enabled in config)

    zef list cpan --cpan       # (or enabled via a cli flag)



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



#### **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 step for each distribution located in the given \[`@paths`\]



Set the env variable **ZEF\_BUILDPM\_DEBUG=1** or use the _--debug_ flag for additional debugging information.



If you want to create a build hook you have two options:



* **PREFERRED** List a builder module that can do what you need in the `builder` field of the META6.json file. For instace many cases of the I-need-to-run-make pattern can list `"builder":"Distribution::Builder::MakeFromJSON"` and supply some extra info to the `"build"` field (a non-standard `Distribution::Builder::MakeFromJSON` specific field). For a more concrete example check out how `Inline::Perl5` [uses the builder field](https://github.com/niner/Inline-Perl5/blob/2e7b99fb03d182d15df4f88818d835b151117786/META6.json#L58-L68). Remember to add any such module to your `build-depends` though! See `Zef::Service::Shell::DistributionBuilder` for more information.



* **DEPRECATED** (_but probably never going away_) Put the following dependency-free boilerplate in a file named `Build.rakumod` at the root of your distribution:



    ```

    class Build {

        method build($dist-path) {

            # do build stuff to your module

            # which is located at $dist-path

        }

    }

    ```



#### **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/Raku-Net--HTTP/issues



    # only outputs the url

    $ zef browse Net::HTTP bugtracker --/open

    https://github.com/ugexe/Raku-Net--HTTP/issues



#### **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

    ===> From Distribution: zef:ver<*>:auth:api<>

    lib/Zef/CLI.rakumod => ~/rakudo/install/share/perl6/site/sources/A9948E7371E0EB9AFDF1EEEB07B52A1B75537C31



    $ zef locate Zef::CLI

    ===> From Distribution: zef:ver<*>:auth:api<>

    lib/Zef/CLI.rakumod => ~/rakudo/install/share/perl6/site/sources/A9948E7371E0EB9AFDF1EEEB07B52A1B75537C31



    $ zef locate lib/Zef/CLI.rakumod

    ===> From Distribution: zef:ver<*>:auth:api<>

    Zef::CLI => ~/rakudo/install/share/perl6/site/sources/A9948E7371E0EB9AFDF1EEEB07B52A1B75537C31



#### **nuke** \[StoreDir | TempDir\]



Deletes all paths in the specific configuration directory



#### **nuke** \[site | home\]



Deletes all paths that are rooted in the prefix of the matching CompUnit::Repository name



    # uninstall all modules

    $ zef nuke site home



## Output Verbosity



You can control the logging level using the following flags:



    # More/less detailed output

    --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.



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`. 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

        ...



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 `$*HOME/.config/zef/config.json` file.



    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). Alternative one can set the `XDG_CONFIG_HOME` env variable to instead look

    in `$XDG_CONFIG_HOME/zef/config.json`.



- You can override both of the previous entries by passing `zef --config-path="$path" `



### Configuration fields



#### Basic Settings



- **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.rakumod_ (`Repository` `Fetcher` `Extractor` `Builder` `Tester` `Reporter`)



The descriptions follow this format:



    {

        "short-name" : "fez",

        "enabled" : 1,

        "module" : "Zef::Repository::Ecosystems",

        "options" : { }

    }



and are instantiated via



    ::($hash).new(|($hash)



- **short-name** - This adds an enable and disable flag by the same name to the CLI (e.g. `--fez` and `--/fez`) 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/main/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

    ===> Testing [OK] for Text::Table::Simple:ver<0.0.3>:auth

    ===> Installing: Text::Table::Simple:ver<0.0.3>:auth



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'"

    ok
