Re: [Pharo-project] Issue 3523 in pharo: Nested comments

Comment #5 on issue 3523 by renggli: Nested comments http://code.google.com/p/pharo/issues/detail?id=3523 Fist of all, C/C++/Java/C#/JavaScript comments go like this: /* some comment */ In any case, introducing that into Smalltalk doesn't work because both #/* and #/* are valid binary selectors and it would be highly ambiguous to parse something like this: 12 /* some comment */ a A combination with the double-quotes $" could work and would avoid the ambiguity: "* some comment "* some nesting *" *" Otherwise, I am afraid there is no other character to introduce nested comments.

Re: [Pharo-project] Why Sets need to be rehashed when loading them from an ImageSegment?

by Lukas Renggli

Any object that uses an identity hash anywhere in its #hash might change its hash, thus the rehashing. Lukas On Monday, 10 January 2011, Mariano Martinez Peck <marianopeck(a)gmail.com> wrote: > Hi.

This is usually the case when you want to load the object subgraph in another image or when do it backups so that to start with a clean image.Â Notice that the Set rehash only occurs in this case. If we use ImageSegment just to swap out / in, there is no Set rehash. > So...I think that this has something to do about WHY Set instances need to be rehashed. > > For each object ImageSegment write into the file, it writes both: object header + slots.Â Â So....the hash (12 bits in the object header) is copied. When the object is loaded back, it continues to have the same hash. It doesn't change. > So...if hash doesn't change, why Set instances need to be rehashes when they come back from an ImageSegment? > > Thanks in advance, > > Mariano > -- Lukas Renggli www.lukas-renggli.ch
