=head1 NAME
Test::Count::FileMutator - modify a file in place
=head2 my $filter = Test::Count::Filter->new({%args});
C<%args> may contain the following:
=over 4
=item * filename
The filename of the file to mutate.
=item * assert_prefix_regex
Passed to L<Test::Count>.
=item * plan_prefix_regex
The prefix regex for detecting a plan line: i.e: a line that specifies
how many tests to run. Followed immediately by a sequence of digits containing
the number of tests. The latter will be updated with the number of tests.
Can be a regex or a string.
=back
=head2 $filter->modify()
Modify the file in-place.
=head1 VERSION
version 0.1105
=head1 SYNOPSIS
    # TODO: fill in
    #
=head1 DESCRIPTION
After initiating a parser one can input assignment expressions, and count
update expressions. Both of them use arithmetic operations, integers, and
Perl-like variable names.
At the end one should call C<$parser->get_count()> in order to get the
total number of tests.
=head1 FUNCTIONS
=head2 $parser->update_assignments({'text' => $mytext,})
Updates the parser's state based on the assignments in C<$mytext>. For
example if C<$mytext> is:
     $myvar=500;$another_var=8+$myvar
Then at the end C<$myvar> would be 500 and C<$another_var> would be 508.
=head2 $parser->update_count({'text' => $mytext,})
Adds the expression inside C<$mytext> to the internal counter of the
module. This is in order to count the tests.
=head2 my $count = $parser->get_count()
Get the total number of tests in the parser.
