Re: [Bug-apl] No errro message when defining functions using

[Elias Mårtenson]

Thank you. I did not realise that the number indicated the line where the error occurred. I have updated the Emacs mode to display an error message and highlight the line where the error occurred now.

Is there a way to get more detailed information as to what the error was? Right now I simply display "Parse error" but it would be nice if it was a bit more precise.

Regards,

Elias

Hi Elias,

not on my machine:

      ⎕FX 'foo[x]' 'x'
1
      )fns

Could it be that you had foo defined earlier?

The syntax error is then due to a niladic function called with an axis
(which is no a valid pattern in APL).

The return value of 1 is the index of the line that has caused the error (foo[x]).

When I try to define a function that takes no arguments, but does include an axis argument, the normal function editor complains:

      ∇foo[x]

bad editor command '∇foo[x]' : problem 'Bad function header at Nabla.cc:495'

DEFN ERROR

      ∇foo[x]

            ^

However, if I try to define the same function using ⎕FX, it gets defined:

      ⎕FX 'foo[x]' 'x'

1

      )fns

EMACS_NATIVE    bar     foo     

But, it cannot be called:

      foo[1]

1

SYNTAX ERROR

      foo[1]
