Apparently #2 value is a number? but the parser parses it.

hello stef, recently i poked with scanner/parser and i wonder what possible literals/combinations are correct and what is not: - a well known: #word , #keyword(s) -- Symbolic literal #- #* ... etc. Symbolic literal #( ...) -- array literal - now what about these: #123 -- number, or '123' asSymbol? ##( ... ) --- ?? ##word --- ?? ##... -- ??? ###... --- ???

Yeap it would be good to fix that. for me #2 -> #'2' ## -> #'#' #something that is not a ( should be #'something' Stef On Oct 10, 2008, at 5:38 PM, nicolas cellier wrote:

Hehe

that reminds me http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/117145.html http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/117153.html

I see not all are fixed in old compiler. Also note the discrepancy between parsing and printing You might want to fix #isLiteralSymbol: too...

#2 -> #'2' ## -> #'#'

so, ##word should be treated as:

'#' asSymbol word

'#' asSymbol produces #'#' so I do not know if this is what I want but we could have #something -> #'something' so #123 - returns a symbol and not a number. and keep #( #{ #( for stuff if we want in the futur. #[ ] #{ } #( )

## is questionable: we can accept such a syntax, but what for exactly?

If no valuable reason, shouldn't we better enforce syntaxic check in Parser and signal malformed statements as an error as would any other Smalltalk?

Quite sure that NewCompiler already fix all this stuff. What are the plans about its integration? Waiting for Eliot's COG?

Anyway, even with NewCompiler, #isLiteralSymbol: and also #numArgs need fixes. These two are probably related to alternate syntax experiments. Google this one: alternate syntax site:lists.squeakfoundation.org Since bugs are hanging around for too long, it is high time to correct. http://lists.squeakfoundation.org/pipermail/squeak-dev/2000-April/005341.htm... http://lists.squeakfoundation.org/pipermail/squeak-dev/2004-March/075166.htm... http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/117145.html and also: http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-July/119095.html Pharo is the ideal place to commit these changes. I will give it a try.
