Error_size

-- Option variable: error_size Default value: 10

error_size modifies error messages according to the size of expressions which appear in them. If the size of an expression (as determined by the Lisp function ERROR-SIZE) is greater than error_size, the expression is replaced in the message by a symbol, and the symbol is assigned the expression. The symbols are taken from the list error_syms.

Otherwise, the expression is smaller than error_size, and the expression is displayed in the message.

See also error and error_syms.

Example:

The size of U, as determined by ERROR-SIZE, is 24.

          (%i1) U: (C^D^E + B + A)/(cos(X-1) + 1)$

          (%i2) error_size: 20$

          (%i3) error ("Example expression is", U);

Example expression is errexp1 -- an error. Quitting. To debug this try debugmode(true);

          (%i4) errexp1;
                                      E
                                     D
                                    C   + B + A
          (%o4)                    --------------
                                   cos(X - 1) + 1
          (%i5) error_size: 30$

          (%i6) error ("Example expression is", U);

E D C + B + A Example expression is -------------- cos(X - 1) + 1 -- an error. Quitting. To debug this try debugmode(true);

(%o1)                                true
