Document layout with Pharo
by Sergio Ruiz Jan. 15, 2024

Jan. 15, 2024

Hi, all. I am looking to create a newspaper like listing of movie showtimes. Initially, I thought of using imagemagickâs annotate command to generate the output. Thinking further, I thought it might be worthwhile to generate a LaTeX file, and render that to a jpg. Then, I thought there might be a better way to do this natively in smalltalk. Does anyone have any idea how I might generate a document that can be converted to an image with a reasonable amount of control of the layout? Thanks!

Updating objects in the inspector
by sergio ruiz Jan. 15, 2024

Jan. 15, 2024

Hi, all. I have been away from Pharo/Smalltalk for several years, but I am coming back to it now. I am a senior developer, but havenât used smalltalk in any professional projects. I also found that I donât do ANY pet projects for fun anymore, as the current batch of languages/frameworks are not fun. They are effective and all. But not fun. I am starting a bunch of âscratch my own itchâ projects. Iâll be using Pharo as the data store, and maybe more. The thing I really want to do is document the usage of Pharo in my projects, and explain the toolchain, and why i chose each piece. My first project is to take a list of movie events from the local theater and create a listing reminiscent of the newspaper listings we read in the olden days. I have my models set up and figured out, but I have a really simple question. How do i change the value of an instance variable in the inspector. It looks like it should be super simple, but itâs not working. In this case, I am just trying to take the period out of a string. See that attached image. Thanks, all! ï¿¼ ---- peace, sergio photographer, journalist, visionary Public Key: https://pgp.key-server.io/pks/lookup?op=get&search=0x69B08F58923AB3A2 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV @sergio_101@mastodon.social https://sergio101.com http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

I am trying to remove some objects from an OrderedCollection in the inspector. I have class called Event. This has a class variable called Events which is a storage are for and ordered collection of Events. So, i inspected âEvent Eventsâ and I see my ordered collection. In the inspector, I select on of the objects, and I try to evaluate âEvent Events remove: selfâ.. But I am getting an error: an Event not found in OrderedCollection. Does anyone have any ideas on how iâd do this?

Call for chapters
by stephane ducasse Jan. 6, 2024

Jan. 6, 2024

Welcome to this collaborative book. We are looking for contributions to new tools in the Pharo ecosystem. Here is a non-exhaustive list of possible tools we have in mind. Development tools such as refactoring, memory usage, and new approaches to debugging Development tools such as UI builders Development tools to develop compilers Tools for modeling such as Cormas, Moose Libraries as basis for advanced tools Each chapter will be reviewed by three reviewers. We expect the chapters to describe the tools, present some clear scenarios, describe key elements of implementations, evidence of use of the tools, Submission process: A chapter must be written in Microdown. Writers may want to clone the current repository and use Pillar (see https://github.com/pillar-markup/pillar and https://github.com/pillar-markup/microdown) The Sample1 folder in the Chapters folder contains a sample chapter. The authors should send an email to stephane.ducasse(a)inria.fr <mailto:stephane.ducasse@inria.fr>, goca(a)dmi.uns.ac.rs <mailto:goca@dmi.uns.ac.rs>, and juanpablo.sandoval(a)uc.cl <mailto:juanpablo.sandoval@uc.cl>. The authors should then do a PR to this repository with their chapter containing all their files. The length of each chapter is not fixed but authors should make sure that the chapter is not either too short or too long. It is worth to see that the format is good for tutorials but is not compact. We will give feedback on this aspect. As usual the material should be new and unpublished. Citations should be expressed using the microdown citation e.g. {!citation|ref=Blac09a!} using {!citation|ref=Blac09a!}, A chapter must be spellchecked with a system such as grammarly, if needed, each chapter should contain a bibfile having the same name than the main folder file, if needed each chapter should contain a folder named 'figures' that contains the figures of the chapter. The Sample1 folder illustrates this structure, it contains: Sample1.bib Sample1.md figures/pharo.png figures/rmod.png This book will be published via the book-on-demand program of http://bod.fr <http://bod.fr/>. It will be published on the Bibliotheque Nationale de France and it will be available on most public platforms such as amazon.com. S. Ducasse, G. Rakic and J-P Sandoval -------------------------------------------- StÃ©phane Ducasse http://stephane.ducasse.free.fr / http://www.pharo.org 03 59 35 87 52 Assistant: Aurore Dalle FAX 03 59 57 78 50 TEL 03 59 35 86 16 S.
