如何禁用Term::ReadLine
的默认完成,或者更确切地说,在某些时候停止建议文件名完成?
例如,我需要更换return()
以禁止从第二个字开始的默认完成?
这些都不起作用:
$attribs->{'filename_completion_function'}=undef;
$attribs->{'rl_inhibit_completion'}=1;
use Term::ReadLine;
my $term = new Term::ReadLine 'sample';
my $attribs = $term->Attribs;
$attribs->{attempted_completion_function} = \&sample_completion;
sub sample_completion {
my ( $text, $line, $start, $end ) = @_;
# If first word then username completion, else filename completion
if ( substr( $line, 0, $start ) =~ /^\s*$/ ) {
return $term->completion_matches( $text,
$attribs->{'username_completion_function'} );
}
else {
return ();
}
}
while ( my $input = $term->readline( "> " ) ) {
...
}
答案 0 :(得分:1)
定义completion_function
而不是attempted_completion_function
:
$attribs->{completion_function} = \&completion;
然后return undef
如果完成应该停止,return $term->completion_matches($text, $attribs->{filename_completion_function})
如果文件名完成将接管。
在以下示例中,没有为第一个参数建议任何内容,但文件名是针对第二个参数。
use Term::ReadLine;
my $term = new Term::ReadLine 'sample';
my $attribs = $term->Attribs;
$attribs->{completion_function} = \&completion;
sub completion {
my ( $text, $line, $start ) = @_;
if ( substr( $line, 0, $start ) =~ /^\s*$/) {
return
} else {
return $term->completion_matches($text, $attribs->{filename_completion_function})
}
}
while ( my $input = $term->readline ("> ") ) {
exit 0 if $input eq "q";
}
