cURL wrapper

cURL wrapper (alias cw) is an attempt for parsing cURL's output transfer statistics. I wanted it as tiny as possible, that's why it's written using C language.

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
 15 20.0M   15 3125k    0     0  2279k      0  0:00:08  0:00:01  0:00:07 2279k

It is a set of (standalone) commandline tools containing:

• c2z: Frontend using Zenity (progress bar widget)
• cw: Unix pipe filter command

This software is still very beta. I'll gradually improve it over time.

CLI usage

Replace cURL command. Arguments are given verbatim to curl program and zenity is launched.

$ c2z http://www.foo1234.com/20MiB.tar -o 20MiB.tar

Note: curl's simple progress bar switch (-#) is handled too.

Parse statistics coming from stdin and write results on stdout:

$ curl http://www.foo1234.com/20MiB.tar -O -J 2>&1 | cw

# 1% (784k/s)
14
# 14% (2199k/s)
31
# 31% (2661k/s)
47
# 47% (2872k/s)
64
# 64% (3002k/s)
88
# 88% (3566k/s)
100

Compilation

To build, run ./autogen.sh && ./configure && make.

There is a specific switch for chosing async event wait: --with-iowait. select, ppoll or epoll can be selected. Default is autodetect.
