Improviz Web

A web version of Improviz

The main parser and gfx engine of Improviz Web is available separately so it can be embedded into other JavaScript systems.

The bundle exports a single function createImproviz which can be called and passed a canvas, and will return either one of two objects.

{
  status: 'error',
  message: 'error message text',
}

{
  status: 'ok',
  improviz: <ImprovizInstanceObject>
}

The instance of the Improviz object has a fairly basic API.

evaluate(program) Give Improviz a program to evaluate each frame. Will return an array with any RuntimeErrors.
genAnimateFunc() Returns the animation function that should then be called each frame. This function will also return an array with any RuntimeErrors each time it's called.

These are simple objects that can be used to alert the user to errors in the program. They have the following attributes.

name The name of the error
line A zero indexed integer denoting which line the error is on
character A zero indexed integer denoting which character the error starts at
message A message giving further information about the error
length An integer stating how many characters long the error token is, useful if underlining it is required.
