using , as decimal point

Hi,

I like to use fractions in my web forms. Unfortunately everything regarding numbers is nailed to use a dot (.) as decimal separator. In magritte it should be fairly easy to delegate the decimal point to the MANumberDescription but then there is still Number class>>readFrom: that checks for dot as well.

Do you have any ideas how to treat this case? I'm not sure if converting at the appropriate locations is feasible.

Norbert

It is probably the easiest if you replace all the $, with $. before
you pass it on to #readFrom:

Do you think it is feasible to change

MAStringReader>>visitNumberDescription:

from

(contents occurrencesOf: $.) > 1
ifTrue: [ MAReadError signal ].

to

(contents occurrencesOf: aDescription decimalPoint) > 1
ifTrue: [ MAReadError signal ].
(contents occurrencesOf: aDescription decimalPoint) = 1
ifTrue: [ contents := contents copyReplaceAll: aDescription decimalPoint with: '.' ].

?

Yes, that should do it.
