Some Perl-Related Bugs and How They Were Fixed.

In this entry, I'd like to tell about several Perl-related bugs I have run into, and how they were fixed. I know I have not been blogging a lot lately, but, on the bright side, I was busy coding.

The "sky" command-line application and other Recent hacktivity

If you have a good web hosting, you may have run into a pattern, where you are uploading files to it for other people to download and need to find the URL where they were uploaded to. Thing is - recalling the exact Rsync (= a file uploader) command and then going to the web browser to access the URL is time-consuming, and repetitive. sky, written in Perl using Moo and available on CPAN, aims to fix all that.

Here is a sample invocation from the web-site:

shlomif@telaviv1:~$ sky up /home/music/Music/mp3s/Thierry\ de\ Massia/Elements\ essentiels/01\ -\ Le\ vent.ogg
X11 forwarding request failed on channel 0
sending incremental file list
01 - Le vent.ogg
     5271287 100%  147.24kB/s    0:00:34 (xfer#1, to-check=0/1)

sent 5272011 bytes  received 31 bytes  87141.19 bytes/sec
total size is 5271287  speedup is 1.00
Got URL:

As you can see, we just specified the file, and it divined the rsync command and gave us the resultant URL. Convenient.
