=head1 DESCRIPTION

Utilities for the testrail command line functions.

=cut

package TestRail::Utils;

use strict;

=head1 FUNCTIONS

=head2 userInput

Wait for user input and return it.

=cut

sub userInput {
 local $| = 1;
 my $rt = <STDIN>;
 chomp $rt;
 return $rt;
}

=head2 parseConfig(homedir)

Parse .testrailrc in the provided home directory.

Returns:

ARRAY - (apiurl,password,user)

=cut

sub parseConfig {
    my ($homedir,$login_only) = @_;
    my $results = {};
    my $arr =[];

    open(my $fh, '<', $homedir . '/.testrailrc') or return (undef,undef,undef);#couldn't open!
    while (<$fh>) {
        chomp;
        @$arr = split(/=/,$_);
        if (scalar(@$arr) != 2) {
            warn("Could not parse $_ in '$homedir/.testrailrc'!\n");
            next;
        }
        $results->{lc($arr->[0])} = $arr->[1];
    }
    close($fh);
    return ($results->{'apiurl'},$results->{'password'},$results->{'user'}) if $login_only;
    return $results;
}

=head2 getFilenameFromTAPLine($line)

Analyze TAP output by prove and look for filename boundaries (no other way to figure out what file is run).
Long story short: don't end 'unknown' TAP lines with any number of dots if you don't want it interpreted as a test name.
Apparently this is the TAP way of specifying the file that's run...which is highly inadequate.

Inputs:

STRING LINE - some line of TAP

Returns:

STRING filename of the test that output the TAP.

=cut

sub getFilenameFromTapLine {
    my $orig = shift;

    $orig =~ s/ *$//g; # Strip all trailing whitespace

    #Special case
    my ($is_skipall) = $orig =~ /(.*)\.+ skipped:/;
    return $is_skipall if $is_skipall;

    my @process_split = split(/ /,$orig);
    return 0 unless scalar(@process_split);
    my $dotty = pop @process_split; #remove the ........ (may repeat a number of times)
    return 0 if $dotty =~ /\d/; #Apparently looking for literal dots returns numbers too. who knew?
    chomp $dotty;
    my $line = join(' ',@process_split);
    
    #IF it ends in a bunch of dots
    #AND it isn't an ok/not ok
    #AND it isn't a comment
    #AND it isn't blank
    #THEN it's a test name

    return $line if ($dotty =~ /^\.+$/ && !($line =~ /^ok|not ok/) && !($line =~ /^# /) && $line);
    return 0;
}
