=head1 NAME

pwd2mod - Try to guess/extract module name from current directory

=head1 VERSION

This document describes version 0.745 of pwd2mod (from Perl distribution App-PMUtils), released on 2024-08-30.

=head1 SYNOPSIS

 % pwd
 /home/ujang/proj/perl-Foo-Bar

 % pwd2mod
 Foo::Bar

 % cd
 % pwd
 /home/ujang

 % pwd2mod
 .

=head1 DESCRIPTION

Will return C<.> if module name cannot be guessed.

=head1 OPTIONS

C<*> marks required options.

=head2 Output options

=over

=item B<--format>=I<s>

Choose output format, e.g. json, text.

Default value:

 undef

Output can be displayed in multiple formats, and a suitable default format is
chosen depending on the application and/or whether output destination is
interactive terminal (i.e. whether output is piped). This option specifically
chooses an output format.


=item B<--json>

Set output format to json.

=item B<--naked-res>

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

 [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd
element) as well as result metadata/extra result (4th element) instead of just
the result (3rd element). However, sometimes you want just the result, e.g. when
you want to pipe the result for more post-processing. In this case you can use
C<--naked-res> so you just get:

 [1,2,3]


=item B<--page-result>

Filter output through a pager.

This option will pipe the output to a specified pager program. If pager program
is not specified, a suitable default e.g. C<less> is chosen.


=item B<--view-result>

View output using a viewer.
