separator character?

Does Squeak allow any character other than 0-9a-zA-Z: in a message name? I
want to exploit some naming patterns and could make good use of a separator
character.

Thanks,

Sophie

I think that there are hacks available to enable $_ to be used in
message Selectors.
I have also discovered that $˚ works as a separator.

At the moment, no.
Smalltalk mostly uses the "CamelCase" convention. The underscore
character _ used in many other programming languages had been used for
the assignment operation (being displayed as a left arrow in the
original Smalltalk-80 fonts).
Squeak still support using _ as assignment and thus can't use it in
identifiers. Other Smalltalk implementations have been using := for
assignment either from the beginning (such as VAST) or after some years
of customers nagging (such as VW :-) ).
There have been discussions on the Squeak mailing list, but at the
moment it does not seem to be planned for the near future.
Personally, I would like to have _ available in identifiers.

Cheers,

You can find out the characters which can start and/or can be part of a
name in Scanner>>#initialize :)

With Glorp installed you can use underscore for all but the first character.

Sure it does. For example, U+3000 (Ideographic space) is no
different from other characters that "can be the initial of global"
*and* also "can be the initial of locals".

So the attached pictures shows a class in Japanese Hiragana
characters with space and a method name with space.

There are many other obscure symbols and characters so you can
probably pick one.
