I'm wondering what sort of tools you intend to develop for acting on the parse trees. Tools to generate and calculate attribute grammars and such would be very useful. Daniel

[ENH] StartUp/ShutDown - less than perfect
by Mats Nygren 02 Jun '00

02 Jun '00

Hi, It seems to be a bad idea to have two separate lists StartUpList, ShutDownList for closing and reopening the image. This invites problems: SoundPlayer - stops on save doesnt start again Solution: add it to StartUpList I havent tried this. PWS - Stops on ShutDown, doesnt start on StartUp. Solution: add it to StartUpList. (In SystemDictionary class>>initialize) This I have tried, see manual ChangeSet below. The PWS will then continue to run until stopped. Try starting it, save and quit, restart, it will run again. There is obviously a general pattern here, whatever is frosen on shutdown should be thawed on startup. Better to have one list. It could be called FreezeList for instance. Send startUp in order at startup, send shutDown in reverse order at shutdown. The default will then be that things continue to work transcending save/restore. Questions: Why is this initialized within SystemDictionary not in aClass>>initialize? Why is this restricted to classes? Why not give any object that wants it shutDown/startUp messages? /Mats Nygren -- ChangeSet (kind of) -- " SystemDictionary class>>initialize add: Smalltalk addToStartUpList: PWS. before: Smalltalk addToStartUpList: ImageSegment.

Here's a quick change set (what's the difference between a change set and a file in?) that should fix the problem people are having under WindowsCE. Essentially Squeak assumes that any Windows OS is going to prepend a drive letter and : to the path, which CE does not. This causes any number of problems, including not being able to find .source files, or file in change sets. By the way, is anyone else running Squeak on a Clio? I've got the exact same setup, and it runs beautifully. No need to even shrink the image.

RE: [BUG] Celeste - names with non-ascii characters
by Raab, Andreas 02 Jun '00

Oh well, I guess Bob is right. There isn't actually any such thing as a #characterNotInFont anymore. Every character has a glyph (which might be the "character not in font" glyph) but there's no reason why a character should not exist in the font. Now should I feel sorry or not for "accidentally fixing" this?! ;-) - Andreas > -----Original Message----- > From: Bob Arning [mailto:arning@charm.net] > Sent: Thursday, June 01, 2000 2:06 PM > To: squeak(a)cs.uiuc.edu > Cc: recipient list not shown > Subject: Re: [BUG] Celeste - names with non-ascii characters > > > On Thu, 01 Jun 2000 12:57:04 +0200 Stefan Matthias Aust > <sma(a)3plus4.de> wrote: > >At 20:17 30.05.00 +0300, you wrote: > >>When showing a message from "Göran" Hultgren <gohu(a)rocketmail.com>, > >>Celeste cuts off the line in the TOC right after the $G. > >> > >>Anyone have any idea why? > > > >How does one reproduce this bug.
