My pending contributions
by Christoph Thiede 30 Jul '19

30 Jul '19

Hi all, over the past weeks, I uploaded several proposals into the inbox. There are a few commits that haven't been resolved yet: - Implement SyntaxErrorNotification>>#resume: (Compiler-ct.405 and Tests-ct.412) - Fix SyntaxErrorNotification>>#messageText (Compiler-ct.406) - Fix two Compiler bugs (Compiler-ct.404 and Compiler-ct.407) - SyntaxError: Preselect error message, and enable styling (Morphic-ct.1492 and Tools-ct.851) - Implement #spawn on SearchBar (Tools-ct.850) - Integrate TestRunner into Browser (SUnitTools-ct.5 and SUnitGUI-ct.70) - Introduce context-dependent styling for Shout (ShoutCore-ct.66) - Add Model>>#aboutToStyle:forMorph (ToolBuilder-Morphic-ct.228) - Allow styling in Inspector's and Debugger's value panes (Tools-ct.852, Tools-ct.853, and Tools-ct.854) I would be very interested to know what is happening with them: Will anyone review these changes, do you think they should be reworked? What are the prerequisites for a commit to be released into Trunk? I am new to the mailing list and not yet familiar with the usual processes. Should I always write a separate email to ask for reviews? I would be very happy about some feedback to my proposals! :) Best, Christoph -- Sent from: http://forum.world.st/Squeak-Dev-f45488.html

Bug: explore pointers: subscript out of bounds if CompiledMethod among parents
by Jakob Reschke 29 Jul '19

29 Jul '19

Looks like PointerExplorerWrapper>>memberNameFrom:to: does not take into account that there are objects (CompiledCode instances) that don't allow to access to the first bytes (only >= initialPC). [image: Error# subscript is out of bounds 1.png]

Longterm stability of image formats
by Philip Bernhart 29 Jul '19

29 Jul '19

Hi, I just wondered of how stable the current image format is supposed to be. When for example I would write now a project for say squeak5.2 and then that project gets abandoned for some reason but still runs in production, would a squeak VM in 10 years still be able to open it? As far as I know these changed over the years because of: 1. Switches from architecture 16 bit -> 32 bit -> 64 bit 2. Switches in VM technology: Cog, Spur, Siesta(?), etc. Is it even naive to believe to be able to open an old image file in the newest VM? Thanks for your time, Philip

Squeak interface to microsoft app automation?
by tim Rowledge 27 Jul '19

27 Jul '19

I'm trying to find any pointers to COM (or similar) interfaces for driving Windows apps (things like getting the text out of a word doc etc) for Squeak. So far all the googling has found way too many unrelated things, so I'm clearly not finding effective search terms. I really don't care about automated floor-squeak removal tools... and I don't seem to be homing in on anything useful. Does anyone have any pointers? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Why use one word when two polysyllabic agglomerates will do?

Trygve's recent paper
by Keith 26 Jul '19

26 Jul '19

Hi Squeakers, I thought you guys might appreciate this, published yesterday on the object-composition forum. I am sure that Trygve needs no introduction here, check out Section F! Keith ====== Dear all, The final draft of my magnum opus about personal programming with DCI is now ready for review: http://folk.uio.no/trygver/themes/Personal/PP-019%20-%20Copy%20(17).pdf Its main theme is personal programming for everybody with Loke, a personal object computer. The first goal is to empower laypeople to take control over their corner of the Net with its IoT. Its 43 pages has several high points, I have included one of them below. I will appreciate your possible comments before Aug. 31. Enjoy --Trygve
