Generates

Missing '=' in parameter 'shigher-order-functions'

The problem is that the method quit() in command.js doesn't do what it says; I think it once did, but this was changed when we made everything asynchronous.

Updated by Norm Tovey-Walsh almost 4 years ago

  • Status changed from New to Resolved

Without trying to hard to unwind the parallelism, there were two easy fixes:

  1. Throw an XError instead of an Error for a bad command line option. That makes command.js print only the message, not the stack trace.
  2. After checking the command line arguments in main; if something's gone wrong, return without trying to do any further processing.
