我的所有主题都希望将他们的进度打印到终端的同一行。我无法让他们选择不同的线条。我该怎么处理? (linux& windows,如果可能的话)
编辑:
我尝试了两种变体:
1
当我打印'\ n'时,线条会下移,\ b不会删除\ n字符:
if ( !($x % 10) )
{
local $| = 1; # Or use IO::Handle; STDOUT->autoflush;
# remove prev progress
print "\b" x length($progressString) if defined $progressString;
# do lots of processing, update $counter
$progressString = "Thread #$tid. $x / $length1"; # No more newline
print $progressString; # Will print, because auto-flush is on
}
2
类似地
my $progress = Term::ProgressBar->new($length1);
$progress->update($x);
提前谢谢你。

我的脚本的工作变体如下:
use Win32::Console::ANSI; # for Windows and nothing for linux
# ...
#---OUTPUT----------------------
if ( !($x % 10) ) {
local $| = 1;
# Choose the line for thread ($i - thread_id)
print "\n" x $i;
# Remove prev. progress
print "\b" x length($progressString) if defined $progressString;
# Do lots of processing, update
$progressString = " Thread #$i. $x / $length1";
print $progressString; # Will print, because auto-flush is on
print "\e[A" x $i, "\r"; # Back to begin before printing
}
