Pharo dark window buttons

by pumps-moats.0i＠icloud.com

Pardon if this is a duplicate but, is there a way to change the themeâs color for the windows close/collapse buttons? They are too dark for me (black on dark grey background). Iâm somewhat visually impaired so the extra contrast would help. I looked at the settings/preferences and couldnât find anything there. Thank you. Regards Pete

UK Smalltalk User Group meeting - 30 November 2022

by Giovanni Corriga

For this month's UKSTUG meeting, Dave Mason will talk about Zag Smalltalk, a new Smalltalk VM written in Zig. Dave Mason ( http://sarg.ryerson.ca/dmason/ ) has been a professor of Computer Science at Toronto Metropolitan University (previously known as Ryerson) for 41 years. He has done research on operating systems, software reliability and programming languages. Current research is mostly around Smalltalk and other dynamic languages. If forced to program very low level projects such as virtual machines, he is willing to use Zig or Rust, but for any other purpose, he insists on using higher productivity languages - primarily Smalltalk. Zag Smalltalk ( https://github.com/dvmason/Zag-Smalltalk ) is a principle-based Smalltalk VM. "Principled" means that the only 3 operations are: message send, assignment, and return. 1) it is designed from the ground up to use multi-processing, to leverage multi-core systems. 2) There is no special-casing of methods like ifTrue:ifFalse or whileTrue:, although of course some methods are implemented by primitive methods. It does aggressive inlining of methods and blocks. 3) âSourceâ code is maintained as ASTs. 4) Compiled code runs in a dual form of threaded code and JITâed machine code that seamlessly interoperate. 5) It has a partially-copying and partially-non-moving garbage collector. 6) It keeps many more values as immediate, including symbols. 7) It uses a single-level dispatch mechanism to implement Smalltalk dispatch semantics The research question is, "Can this be made fast enough to be competitive?â Preliminary results are encouraging. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/290036186 ) to receive the meeting details.

Can you use [SortFunctions](https://github.com/pharo-open-documentation/pharo-wiki/blob/… "SortFunctions") instead of blocks with the SortedCollections? This is what I finally figured out to do with Fuel most of the time after lots of pain

Re: mapping CamelCase to <custom-tag-name>

by Richard O'Keefe

But there IS a #cutCamelCase method in Pharo. It comes from Roassal2. Here it is, copied from Pharo 9.0.0: cutCamelCase "Breaks apart words written in camel case. It's not simply using piecesCutWhere: because we want to also deal with abbreviations and thus we need to decide based on three characters, not just on two: ('FOOBar') piecesCutWhereCamelCase asArray = #('FOO' 'Bar'). ('FOOBar12AndSomething') piecesCutWhereCamelCase asArray = #('FOO' 'Bar' '12' 'And' 'Something') " | start previous current next pieces | self isEmpty ifTrue: [^self]. start := 1. pieces := OrderedCollection new. 3 to: self size do: [ :index | previous := self at: index - 2. current := self at: index - 1. next := self at: index.

Re: STON little question

by stephane ducasse

I found stonProcessSubObjects: block "Execute block to (potentially) change each of my subObjects. In general, all instance and indexable variables are processed. Overwrite when necessary. Not used when #stonContainSubObjects returns false." 1 to: self class instSize do: [ :each | self instVarAt: each put: (block value: (self instVarAt: each)) ]. (self class isVariable and: [ self class isBytes not ]) ifTrue: [ 1 to: self basicSize do: [ :each | self basicAt: each put: (block value: (self basicAt: each)) ] ] but I could not really get how to use it and if it was at the moment of writing. So I will patch my model but to me it defeats the purpose of serialization. Either we can serialize everything or we can transform to that we can fall back on the stable part. Forcing clients to prepare the objects to serialize is always possible but less satisfactory. Because I will have to do it twice. to save from sorted to ordered save from ordered to sorted and on load from ordered to sorted. S

I was considering to hack my own version of STON to avoid to that in my model. Or serializing nicely SortedCollection. May be I missed something obvious. S
