The "hoonlint" command runs checks on one or more hoon files. These may be specified on the command line, or via the "-f" option. Simple example The command hoonlint hoons/examples/toe.hoon lint the Tic-tac-toe example for Hoon (which can be found at...

The purpose of the PPIx-Regexp package is to parse regular expressions in a manner similar to the way the PPI package parses Perl. This class forms the root of the parse tree, playing a role similar to PPI::Document. This package shares with PPI the ...

Data::RenderAsTree provides a mechanism to display a Perl data structure. The data supplied to "render($s)" is stored in an object of type Tree::DAG_Node. "render()" returns an arrayref by calling "Tree::DAG_Node"'s "tree2string()" method, so you can...

This module extracts information contained in the "d" attribute of an SVG <path> element and turns it into a simpler series of steps. For example, an SVG <path> element might take the form <path d="M9.6,20.25c0.61,0.37,3.91,0.45,4.52,0.34c2.86-0.5,14...
