Re: [Pharo-dev] [Success Story] ApptiveGrid - Digitize and Automatize Business Processes

Cool. I think we need to share such success stories with the world through social media under the Pharo account. Just put the link of the story on LinkedIn and share the link here so we can like and share.

UKSTUG Meeting 28 February 2024: Juan Vuletich - Bootstrap & Dynamic Cuis Libraries

by Giovanni Corriga

Juan Vuletich returns to the UKSTUG to discuss some recent enhancements to Cuis Smalltalk ( https://cuis.st/ ) : Bootstrap and Dynamic Cuis Libraries. Bootstrap: Creating Minimal Images from Scratch > * The last ancestor of Cuis Smalltalk that was bootstrapped from scratch was Smalltalk-76. Since then, various released images of Smalltalk-80, Squeak and Cuis were derived by applying updates to the previous one. A new tool called 'Bootstrap' allows the creation of minimal Smalltalk images from scratch. These images are in the Spur 32 and 64-bit formats, compatible with the OpenSmalltalk VM. 'Bootstrap' gives developers complete control over what is included in the new image. It is compact, relatively simple, and easy to extend and adapt. Dynamic Cuis Libraries: A binary format for Cuis code that is powerful and quick to load > * Dynamic Cuis Libraries are binary files with pre-compiled code that can be loaded into a running Cuis image. They can add new classes and extend existing ones. For existing classes, there are no requirements on the shape of that class in the image loading the library. Missing variables are added, extra variables are kept, and both existing and newly loaded methods are adjusted to whatever shape the class has. Juan Vuletich ( https://independent.academia.edu/JuanVuletich ) is the founder and lead developer of Cuis Smalltalk. He is a long-standing Open Source Smalltalk community member, having contributed kernel code to Cuis, Squeak and the Squeak VM for over 25 years. Juan has been programming since he was 14, and doing it professionally since he was 17. He holds an MS.Sc. in Computer Science from the University of Buenos Aires. He works at LabWare. 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/299084123/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

Re: "Print it" redirection

by Richard O'Keefe

What stops you copy and paste? Using ANSI Smalltalk, you'd do [:stream | stream print: 1000 factorial; cr; close] value: (FileStream write: 'factorial.txt'. Pharo has never provided an ANSI-compatible FileStream class, which is a pain for trying to write portable code. In Pharo you have to write 'factorial.txt' asFileReference writeStreamDo: [:stream | stream print: 1000 factorial; cr]. In Pharo 9, you'd have to change #write: to #newFileNamed:. I wanted to check this in Pharo 12, but PharoLauncher has stopped working.

Re: "Print it" redirection

by Tim Mackinnon

Hi - the following is a bit old but might still work (and I plan on revisiting it myself) - but my poor man's Pharo build system does the following (note the | tee which I use to capture any load errors that I can grep and cause a build failure). This might be the kind of thing you are looking for - or as others have said you can run headless. echo -e "\e[1m\nLoading project packages...\e[0m" pharo Pharo.image --no-default-preferences --save --quit st settings.st loadProject.st config.st \ "{'$PROJECT_NAME'. '$DOMAIN_LOGIN'}" 2>&1 | tee LoadProject.log echo -e "\e[1m\nVerifying project load history...\e[0m" if (grep -f ../scripts/errorPatterns.txt LoadProject.log | grep -v -f ../scripts/errorPatternsIgnored.txt); then echo -e "\e[91m\nERRORS detected in package load!\e[0m"; exit 1; fi On Tue, 20 Feb 2024, at 7:46 AM, Rene Paul Mages (ramix) wrote: > Hello Pharo Community, > > Output unix-redirection like the following is very useful : > > ls -al ./Pharo > Pharo-dir.txt > > <Help> > > I want to write in a file the "print-it" output of the following Pharo > message : > > 1000 factorial > > Please give me a good track. > > </Help> > > > -- > All the best > Rene Paul Mages (ramix) GnuPG key : 0x9840A6F7 > http://sites.google.com/view/les-logiciels-libres/pharo > http://nosoftwarepatents.wikidot.com/smalltalk > http://twitter.com/RenePaulMages

Rene Paul, Try this. Example command line from MacOS. ~/Pharo/vms/120-x64/Pharo.app/Contents/MacOS/Pharo --headless pharo12.image eval 1000 factorial Replace ~/Pharo/vms/120-x64/Pharo.app/Contents/MacOS/Pharo by the path to the VM you like to use. Replace pharo12.image by the path to the image you like to use. It will output: 402387260077093773543702433923003985719374864210714632543799910429938512398629020592044208486969404800479988610197196058631666872994808558901323829669944590997424504087073759918823627727188732519779505950995276120874975462497043601418278094646496291056393887437886487337119181045825783647849977012476632889835955735432513185323958463075557409114262417474349347553428646576611667797396668820291207379143853719588249808126867838374559731746136085379534524221586593201928090878297308431392844403281231558611036976801357304216168747609675871348312025478589320767169132448426236131412508780208000261683151027341827977704784635868170164365024153691398281264810213092761244896359928705114964975419909342221566832572080821333186116811553615836546984046708975602900950537616475847728421889679646244945160765353408198901385442487984959953319101723355556602139450399736280750137837615307127761926849034352625200015888535147331611702103968175921510907788019393178114194545257223865541461062892187960223838971476088506276862967146674697562911234082439208160153780889893964518263243671616762179168909779911903754031274622289988005195444414282012187361745992642956581746628302955570299024324153181617210465832036786906117260158783520751516284225540265170483304226143974286933061690897968482590125458327168226458066526769958652682272807075781391858178889652208164348344825993266043367660176999612831860788386150279465955131156552036093988180612138558600301435694527224206344631797460594682573103790084024432438465657245014402821885252470935190620929023136493273497565513958720559654228749774011413346962715422845862377387538230483865688976461927383814900140767310446640259899490222221765904339901886018566526485061799702356193897017860040811889729918311021171229845901641921068884387121855646124960798722908519296819372388642614839657382291123125024186649353143970137428531926649875337218940694281434118520158014123344828015051399694290153483077644569099073152433278288269864602789864321139083506217095002597389863554277196742822248757586765752344220207573630569498825087968928162753848863396909959826280956121450994871701244516461260379029309120889086942028510640182154399457156805941872748998094254742173582401063677404595741785160829230135358081840096996372524230560855903700624271243416909004153690105933983835777939410970027753472000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 Ciao, Koen > On 20 Feb 2024, at 08:46, Rene Paul Mages (ramix) <pharo(a)rmages.com> wrote: > > Hello Pharo Community, > > Output unix-redirection like the following is very useful : > > ls -al ./Pharo > Pharo-dir.txt > > <Help> > > I want to write in a file the "print-it" output of the following Pharo message : > > 1000 factorial > > Please give me a good track. > > </Help> > > > -- > All the best > Rene Paul Mages (ramix) GnuPG key : 0x9840A6F7 > http://sites.google.com/view/les-logiciels-libres/pharo > http://nosoftwarepatents.wikidot.com/smalltalk > http://twitter.com/RenePaulMages

GemConnect (https://gemtalksystems.com/products/gemconnect/) is an add-on product for GemStone that allows you to interact with an Oracle relational database from GemStone. It is used by several customers to dump transactional data to Oracle for reporting. See also GemConnect-for-Postgres (https://github.com/GemTalk/GemConnect-for-Postgres) Less developed is a way to make GemStone look like a relational database. Years (decades!) ago there was a third-party add-on that allowed marketing to check a box in RFPs but it was never taken seriously. More recently (years, but not decades ago), I did a proof-of-concept that demonstrated connecting Microsoftâs ODBC to GemStone (so you could see GemStone data using SQL.
