Screed

======

Screed helps you parse text. It can do some things that a lexer can do, but it

doesn't generate tokens. Instead, you read characters directly in your parser.

You can:

  * Read individual characters

    ~~~ js

    if (reader.matchChar('"')) {

      const char = reader.eat()

      ...

    }

    ~~~

  * Match strings

    ~~~ js

    if (reader.matchString("...")) {

    ~~~

  * Match regular expressions

    ~~~ js

    if (reader.matchRegex(/[A-Za-z0-9_\$]+/)) {

    ~~~

I wrote screed in hopes that it could be used for [_hyperscript][].
