[![Build Status](](


P6Repl::Helper - Convenience functions to help with introspecting objects from Perl6 REPL.


    # Install it
    $ zef install P6Repl::Helper

    # Run the Perl6 REPL with it
    $ perl6 -M P6Repl::Helper

    # Or, load it from the REPL
    $ perl6
    > use P6Repl::Helper;


P6Repl::Helper provides functions to help you explore Perl6 packages (package/module/class/role/grammar) from the REPL.


    # Show the GLOBAL package
    > our sub mysub { 123 }; ls GLOBAL

    # Show only names in the CORE module that have "str" in them
    > ls CORE, :name(/str/)

    # Show all s* subs and their multi candidates if any.
    > ls CORE, :name(/^s/), :long

    # You can also filter on the objects themselves.
    # E.g., show only CORE types(class, role, or grammar)
    > ls CORE, :value(Class-ish)

    # Show only non-sub instances in CORE
    > ls CORE, :value({$^obj.DEFINITE && $^obj !~~ Sub})

    # Show Str's methods that begins with 'ch'. 'll' is like 'ls' but with :long.
    > ll Str, :name(/^ch/)

    # By default only local methods are matched against; specify :all to match
    # against inherited methods as well.
    > ll Str, :name(/fmt/), :all

    # Specifying :gather returns a Seq of Pairs
    > ls CORE, :name(/^sp/), :gather ==> { .value.&ls for $_ }()

    # Once you get a hold of a sub or a method, you can use &doc to open its
    # documentation in a browser.
    > doc &substr

    > ls CORE, :name(/^s/), :numbered
    > doc (ls CORE, :name(/^s/), :take(21))

This is my first Perl6 module, written mainly to learn Perl6; therefore, any corrections/suggestions or help is highly apprecicated!
