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!
