<p style="color: grey"> Python recipe 579146 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/linux/">linux</a>, <a href="/recipes/tags/pdf/">pdf</a>, <a href="/recipes/tags/pdf_generation/">pdf_generation</a>, <a href="/recipes/tags/pipe/">pipe</a>, <a href="/recipes/tags/pipelining/">pipelining</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/python2/">python2</a>, <a href="/recipes/tags/unix/">unix</a>). </p> <p>This recipe shows how to create a Unix pipeline that generates PDF output, under the control of a Python program. 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>

<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>

For instance you can build a pipeline to process web requests easily including some middleware for instance.</p>

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>
