An Online Python re.findall Service

As a programmer, I know that grep, sed and awk are powerful for processing text, but they sometimes aren't that straight-forward for specific tasks, as I need to think about how to filter the lines and the columns out.

So I wonder if there is a handy way to do these tasks?

After using it for a while, I think using regex directly can help, so I launched a re.findall service building on top of Python re.findall API.

ER Diagrams in Plain Text

If you ever wonder how to plot ER diagrams in plain text, you may have already heard of erd. It's a cool command line program written by Andrew Gallant in Haskell, to "compile" plain text files into nicely looking images, leveraging the power of GraphViz.

I've used erd for some time, it's cool and the syntax is quite simple. It's also quite simple to install it on Linux, just install GraphViz and erd itself, by following the instructions in the README page.
