Re: [Pharo-project] Any good shrink scripts for pharo targeting the iPhone with deimos?

A first start is #cleanUpForRelease and #cleanUpForProduction. With this you get down to approx. 7MB.

Personally, I annotate every learning material I get with my own notes, if possible. And new stuff I learn that is related I try to keep at the same place. I think this is interesting especially in Smalltalk where you are encouraged to explore the system. I would expect someone starting with a basic tutorial and then turning to explore the system and documenting the learning process in the help system itself, and even be able to share it with others. A pupil can quickly become a teacher, and quite often the one who has just learned something is the best person to explain it to other newcomers. I see your point for complete newbies, though. So maybe enabling the authoring bar can be made a preference, and the last lesson in an introduction like Laurent's syntax tutorial can contain some code to switch on the bar. Danny

Re: [Pharo-project] Metacello - the missing information??

by Schwab,Wilhelm K

Dale, IMHO, class comments would be far less important than helpful entry points and/or a brain dead simple faÃ§ade interface to the whole thing (call it Loader or whatever else you care to provide). As a could/should-be beta tester of Pharo, I don't so much care how Metacello works as how I am expected to use it. In my own code, I sometimes write class comments, but what I do a LOT is comment inside methods, tagging them with mm-yy[*]. In porting some code to Pharo, I was saved in a big way by some comments from several years ago. There were some long-standing (and previously undetected) bugs in it, and I would have had a hard time fixing them w/o those comments. Bill [*] yes, I use two-digit years for it - shoot me, perferably before 2093 or so when the dates will start to be become ambiguous<g> -----Original Message----- From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Dale Henrichs Sent: Sunday, February 07, 2010 5:50 PM To: Pharo-project(a)lists.gforge.inria.fr Cc: pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Metacello - the missing information?? Henrik, Ahhh, comments ... when I get a comment compiler, I will write comments along with the code... With that said, you are correct that there are missing comments and writing comments _is_ on my todo list. If anyone is interested in taking a crack at writing comments for Metacello (before I get to it), then I would be willing to read and correct them.
