a while back I have pushed a gem “get_mp3” which can be used to download
selected radio-broadcasts from two french radio-stations to the local
My use of the HTTP-connection I have learned from this thread on
Currently, I try to add a download-history to the program which shall
permit a user to finish a discontinued download or to queue downloads
for later execution. For this, I already persist asynchronously the
current position of the file-cursor, file-name and download-url.
What I am missing, is a way to skip the bytes, which are already stored
in the local file and to begin downloading at an advanced
cursor-position, so that eventually the file is completed without having
to overwrite the existing chunks…
You can see all the relevant code in the current get_mp3 gem (on
rubygems.org) or in this pastebin, which mirrors the current
development-state of the main routines:
The answer that I seek should lead to a modified method http_to_file and
a pre-setting of the variable last_pos.
I hope, that this is enough background for you and that I have explained
clearly what I am after.
Thanks in advance,
