## About The Pull Request this adds a new define, `DISABLE_DREAMLUAU` (commented out by default), which does... exactly what it says on the tin. it fully disables any dreamluau-related code (the "Open Lua Editor" admin verb is left in, albeit just giving the user a warning saying Lua is disabled, just so there's no confusion about the verb itself being missing) when compiling with OpenDream outside of CI (so dreamluau code will still be linted), `DISABLE_DREAMLUAU` will be defined by default, tho. ## Why It's Good For The Game makes OpenDream testing easier ## Changelog no user-facing changes. or even code changes for most cases.

/**
|
|
* Byondapi hooks act as "set waitfor = 0" procs. This means that whenever
|
|
* a proc directly called from an external library sleeps, the hook returns with whatever
|
|
* the called proc had as its return value at the moment it slept. This may not
|
|
* be desired behavior, so this datum exists to wrap these procs.
|
|
*
|
|
* Some procs that don't sleep could take longer than the execution limit would
|
|
* allow for. We can wrap these in a promise as well.
