Revision 5. </p> <p>Gets several pages in parallel, without threads. It exploits HTTP pipelining by resetting the state of HTTPConnection to trick it into sending the next request ahead of time.</p> <p>More information about HTTP pipelining can be found on Wikipedia: <a href="http://en.wikipedia.org/wiki/HTTP_pipelining">http://en.wikipedia.org/wiki/HTTP_pipelining</a></p> Pipeline made of coroutines (Python) 2012-09-14T09:53:58-07:00Chaobin Tang (唐超斌)http://code.activestate.com/recipes/users/4174076/http://code.activestate.com/recipes/578265-pipeline-made-of-coroutines/ <p style="color: grey"> Python recipe 578265 by <a href="/recipes/users/4174076/">Chaobin Tang (唐超斌)</a> (<a href="/recipes/tags/coroutine/">coroutine</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/python/">python</a>).

It is tested on Linux. It uses nl, a standard Linux command that adds line numbers to its input, and selpg, a custom Linux command-line utility, that selects only specified pages from its input, together in a pipeline (nl | selpg). The Python program sets up and starts that pipeline running, and then reads input from it and generates PDF output.</p> Create PDF at the end of a Unix pipeline with PDFWriter (Python) 2013-12-22T22:19:00-08:00Vasudev Ramhttp://code.activestate.com/recipes/users/4173351/http://code.activestate.com/recipes/578794-create-pdf-at-the-end-of-a-unix-pipeline-with-pdfw/ <p style="color: grey"> Python recipe 578794 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/commandline/">commandline</a>, <a href="/recipes/tags/linux/">linux</a>, <a href="/recipes/tags/pdf/">pdf</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/reportlab/">reportlab</a>, <a href="/recipes/tags/unix/">unix</a>, <a href="/recipes/tags/xtopdf/">xtopdf</a>). </p> <p>This recipe shows how to create PDF output at the end of a Unix or Linux pipeline, after all the text processing required, is done by previous components of the pipeline (which can use any of the standard tools of Unix such as sed, grep, awk, etc., as well as custom programs that act as filters).</p> rdd (mostly broken but shows how to do a few things in ruby) (Ruby) 2014-07-12T16:58:06-07:00Mike 'Fuzzy' Partinhttp://code.activestate.com/recipes/users/4179778/http://code.activestate.com/recipes/578034-rdd-mostly-broken-but-shows-how-to-do-a-few-things/ <p style="color: grey"> Ruby recipe 578034 by <a href="/recipes/users/4179778/">Mike 'Fuzzy' Partin</a> (<a href="/recipes/tags/dd/">dd</a>, <a href="/recipes/tags/ftp/">ftp</a>, <a href="/recipes/tags/io/">io</a>, <a href="/recipes/tags/net_ftp/">net_ftp</a>, <a href="/recipes/tags/pipe/">pipe</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/popen/">popen</a>, <a href="/recipes/tags/subprocess/">subprocess</a>). Revision 3. </p> <p>Meant to be a slightly more "advanced" dd utility. Supporting FTP/File/STDIN as input streams, and File/STDOUT/PIPE as output targets, and sporting a progress display (very rudimentary atm), add lets you combine network, and file or pipe processing in a single command. But kind of ended up a mess, see the <a href="https://code.activestate.com/recipes/578907-python-awesome-dd/?in=user-4179778">Python version</a> which is pretty clean.</p> Function Pipelines (Python) 2011-05-15T19:38:13-07:00Alexandre Zanihttp://code.activestate.com/recipes/users/4177180/http://code.activestate.com/recipes/577696-function-pipelines/ <p style="color: grey"> Python recipe 577696 by <a href="/recipes/users/4177180/">Alexandre Zani</a> (<a href="/recipes/tags/events/">events</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/wsgi/">wsgi</a>). </p> <p>Pipelines can be used to chain a series of functions to process a piece of data. For instance you can build a pipeline to process web requests easily including some middleware for instance.</p> Function Pipelines (Python) 2011-05-22T20:39:05-07:00Rob Lhttp://code.activestate.com/recipes/users/4178061/http://code.activestate.com/recipes/577714-function-pipelines/ <p style="color: grey"> Python recipe 577714 by <a href="/recipes/users/4178061/">Rob L</a> (<a href="/recipes/tags/events/">events</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/wsgi/">wsgi</a>). </p> <p>Alexandre Zani's recipe on function pipelines was useful. I wanted to change it to suit my needs.</p> <p>Mostly I just wanted to add arbitrary functions and make the pipe line more list like in behavior.</p> <p>(edit: typos)</p>
