| -- a WIP LPeg implementation in pure Lua, by Pierre-Yves Gérardy | |
| -- released under the Romantic WTF Public License (see the end of the file). | |
| -- Captures and locales are not yet implemented, but the rest works quite well. | |
| -- UTF-8 is supported out of the box | |

LPEG is a library for operating on patterns. It is not an alternative to the Lua string library, but it can be used to implement libraries rather like the string library instead of doing it directly in C.
Some words mean very specific things to LPEG.

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

| // the effector must be a function that accepts a DOM node | |
| // (insertion point) and a component, like Mithril;s `m.mount` | |
| // This was done by modifying the code as little as possible | |
| // but the result will need a bit more polish to become universally | |
