How do you get the total size of a torrent in libtorrent?
Question:
How do you get the total size of the files in a torrent?
And is there any way to get the number of files in a torrent and the size of each one?
Answers:
If you take a look at the C++ API you will find that the torrent-info and file_iterator methods a little down the page give you the information you are looking for. The python bindings section states:
The python interface is nearly identical to the C++ interface.
So you should be able to get at these methods with a little effort.
h = ses.add_torrent(params)
s = h.status()
while (not h.is_seed()):
print s.total_wanted # prints total size wanted after meta data is obtained, before that 0 is printed.
/usr/local/bin/torrent-size.py
#!/usr/bin/env python3
import libtorrent
import sys
torsize = 0
info = libtorrent.torrent_info(str(sys.argv[1]))
for f in info.files():
torsize += f.size
print(torsize/1048576, "MB")
This will give you the file size for a torrent provided as the first parameter to the script. Below are instructions to install libtorrent and the libtorrent python bindings. If you get an error about cxxstd on Ubuntu, you need to download boost 1.76, bootstrap it, install it, then copy the source directory to /usr/share/boost-build and export BOOST_ROOT=/usr/share/boost-build and export BOOST_BUILD=/usr/share/boost-build.

Using torrent_parser:

totalsize = 0
for file in torrent_metadata['info']['files']:

print(totalsize)
