在Perl中,Term::ReadLine模块提供了一个接口来自定义阅读行为。要阻止空格被附加到制表符完成的单词,可以通过以下步骤实现:
use Term::ReadLine;
my $term = Term::ReadLine->new('MYAPP');
my $attribs = $term->Attribs;
my $completion_suppress_append_character = 'completion_suppress_append_character';
$attribs->{$completion_suppress_append_character} = ' ';
my @words = qw(apple banana cherry dog elephant);
sub my_completion_function {
my ($text, $line, $start) = @_;
my @matches = grep { index($_, $text) == 0 } @words;
return @matches;
}
$term->Attribs(completion_entry_function => \&my_completion_function);
print "Enter a word: ";
my $input = $term->readline();
print "You entered: $input\n";
通过以上步骤,可以实现在Perl中使用Term::ReadLine模块阻止空格被附加到制表符完成的单词。
