Subject: Re: Discussion about Nile in Pharo
Damien,
That is a great next step. Dumb question: do I already have an
account by virtue of being on the list, or do I need to create one?
Your rewrite to cope with #on: is fascinating, but I continue to
wonder whether it is necessary. In fact, I _think_ I would prefer
to rename the Nile classes (either up front or probably post-install
via the RB) to be generic. While I too prefer idioms such as Array
writeStream and aCollection readStream, #on: is perfectly ok, though
clumsy. What we should do depends on your goal, and of course on
what works best.
Changing to Nile via #readStream and #writeStream has its
advantages, but the rewrite has made me greedy :) I am thinking of
something like the following:
(1) prepare the image by renaming methods (#next -> #nextOrNil:,
#next -> #nextAvailable:) to reflect current silently-truncating
semantics
(2) add the silent truncating methods to Nile; add #on: methods to
Nile, including comments referencing the shortcut methods
(3) change Nile's #next, #next: to raise errors; noting that after
(1), the image will call the truncating methods, and only new code
will see the errors
(4) either Smalltalk at:#ReadStream put:NSReadStream, etc., or
perhaps better yet just ask the RB to rename the Nile classes, so
that one codes in terms of ReadStream, WriteStream, catches
EndOfStream. We can provide a defined set of RB steps that anyone
can use in a throw-away image to prepare code that we did not fix
for them; it should basically be step (1).
Comments? If you at all agree, feel free to edit and put it on the
Wiki while I figure out how to access it.

Hi Bill,
I writing a wiki page where I explain what we can do to slowly
install Nile:
https://gforge.inria.fr/plugins/wiki/index.php?refs=NileInstallation&id=1299&type=g
You can help me with the redaction.
