Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Plot frequency distribution of words from files on a terminal.

Uses the dumb terminal option in gnuplot to plot a graph of frequencies. In this case, we are looking at a frequency analysis of words in all of the .c files.

What others think

I love it. It's an insane extension of Kernighan & Pike's famous wordfreq shell script from their 1984 classic, "The UNIX Programming Environment", which went something like this,

#!/bin/sh cat $* | tr -sc [:alpha:] '[\n*]' | tr [:upper:] [:lower:] | sort | uniq -c | sort -r -n
