[Octave-bug-tracker] [bug #61842] New "too many inputs" error message wrong with anonymous functions

[Rik]

Follow-up Comment #9, bug #61842 (project octave):

@jwe: There is enough information to figure out where the error is.  I just
thought it would be helpful to programmers to list the name of the anonymous
function in the same way we list the name of the function (if it is in an
m-file) that generated the error.

Below is a test script (also attached)


# Line 1
fanon = @() error ("calling error() from anonymous function");

# Line 5 next, error should be in column 5 
#    fanon ();

# Line 8 next, error should be in column 3
  fanon (1);


When run with line 5 uncommented the output is


error: calling error() from anonymous function
error: called from
    @<anonymous> at line 2 column 13
    tst_line_num at line 5 column 5


Note that the call stack references both where the function was called (line
5, column 5) and also where the actual error was thrown (line 2, column 13).

When I comment out line 5 and let line 8 generate the error from the parser I
get


error: : function called with too many inputs
error: called from
    @<anonymous>
    tst_line_num at line 8 column 3


I still have the function invocation information, but not where the anonymous
function was defined.  The extra information would be helpful if it is
available.
