Table of Builtin Functions

Status of builtin function implementation

The following is a table of the status of the implementation of various builtin-functions as defined in the LambdaMOO 1.8 specification, as well as some extensions that were added in ToastStunt and then ported over to mooR. (And some novel extensions added in mooR itself.)

The table is broken down by category, and each function is marked with a checkmark if it is implemented.

If there are any notes about the implementation, they will be included in the notes column. If you notice anything missing, or if you have any questions about the implementation, please feel free to open an issue on the mooR GitHub repository issue tracker.
