Nice! In the why part you speculatively mention better speed. Do you have any concrete benchmark results?<p>If fast, the tool would be very useful for my work where I run an anonimization sed script with hundreds of transformations on millions of lines that takes hours to run.<p>But even if it is not fast, this is a fun project.
wow--impressive!<p>the core is here (<a href="https://github.com/lhoursquentin/sed-bin/blob/master/par.sed" rel="nofollow">https://github.com/lhoursquentin/sed-bin/blob/master/par.sed</a>), and it's 600 lines of beautifully commented sed
