Re: Smallscript - A Smalltalk-Inspired Scripting Language

by Richard O'Keefe

Does anyone else remember F-Script? A "Smalltalk-inspired scripting language" for MacOS X, providing full interoperation with Objective C and the whole Cocoa frameworks system. The last update was 5 years ago, which is a pity, because 1. It was so well integrated with MacOS X (as it was then) that it needs rebuilding wih each macOS release. 2. It was so well integrated with MacOS X that it was restricted to MacOS X; there wasn't anything to port to Windows or Unix. 3. It was Smalltalk - *inspired* but not Smalltalk, so there was no flow of ideas or code between Smalltalk and F-Script. For example, there never was an SUnit for F-Script. Does anyone else remember Susie? (Scripting using a Smalltalk Interpreter engine.) I've been meaning to fix the problem with a 64-bit build but wondering who to tell. It seems as if reviving Susie or GST ought to pay off more sooner than starting from scratch. If you want a "class-less" language inspired by Smalltalk with minimalist syntax, you really MUST look at Self. I used to use XLisp/Stat a lot, and while I loved it, I can't say that not having classes struck me as a strength. Curly braces trace back to BCPL -- which I once set out to write a compiler for. They were and are a bad idea. If you want a scripting language inspired by JavaScript, with braces and sans classes, may I suggest JavaScript? It satisfies 8 out of your criteria out-of-the-box, and node.js with a vast library of stuff to script with, including testing frameworks, already exists. I'm not sure if it satisfies criterion 6 or not, but then I'm not sure what criterion 6 means or why you would care. There are programming languages I dislike *as* languages but use for the sake of the libraries they give me access to, S, for example, ticks quite a few of your boxes. As a language, it's pretty awful. (In large part *because* it ticks those boxes.) BUT the packages! Oh gosh, the *packages* ! All the work I don't have to do! All the work I *COULDN'T* have done! So, one approach is to build your new teenage mutant ninja scripting language on top of something like node.js. Go nuts with your syntax, but make the data structures fully JavaScript-compatible so that you can use existing npm packages from your language. I wish GNU Smalltalk were still maintained. One day I must try to figure out why printing floats crashes.

So much that, what was a short answer became a long reflection on minimal environments that provide support for diverse learners (beyond developers or computer scientists) via data storytelling and computational notebook. Here it comes. ====== I have been using Nim integrated with Pharo/GT when I need go to the console, performance optimizationsÂ or use a library/functionality not yet in Pharo, and I would like a better shell and external programs story in Pharo/GT (I know the second is build on the first, despite having different agendas, but that's the combination I use and for me, GT's power provides from being done in Pharo). I would like something fast and self contained / portable that can be run from the terminal, but it is also able bootstrap a more complex environment and GUI as needs require it, as I'm interested in data storytellingÂ for diverse learners (mainly non-developers) and computational notebooks, that run in restricted/bureaucratic institutional environments with low/restricted/intermittent connectivity (for example university labs). I will compare what is available AFAIK in the Pharo ecosystem, with what I have found recently Pluto.jl[1][1a] (and others), which brings this kind of bootstrappable computational notebook experience, thinking in how Pharoers, could benefit from a bootstrapable experience from shell at the end. 1. Pluto can run from a portable program that doesn't require admin permission to install: just uncompress and run (like Pharo). 2.Â Pluto provides an interactive programming Julia shell where you can load more packages and launch the WUI (Web UI). In Pharo's case, there are Coral[2] and Scale[2a], with the second pretty close to a shell + loadable graphical interface, but both seem unmaintained. 3.Â Pluto provides an interactive notebook interface (like GT), but it is reactive, non-blocking and stores a computational graph of related variables/expressions. 4. Pluto stores its notebooks as human/diff friendly plain text and, in fact, they're just Julia scripts[3] (like Clojure's Clerk[3a][3b]). As I told in ESUG 2023, we have been porting some lessons from Grafoscopio to Lepiter about having human/diff friendly formats to store computational notebooks using Markdeep[4], which is similar to the approach taken by Elixir's LiveBook[3c]. See for example this documents, and their source code, on building modular parsers with PetitParser[4a] (ported from the chapter in Pharo books) or on migrating from WordPress to TiddlyWiki[4b]. Such formats are in contrast with long nested diff/human unfriendly JSON documents of Jupyter or Lepiter, and pretty readable outside Pluto, Clerk, LiveBook or Lepiter, just with a plain text editor or a web browser (in Markdeep's case). So, how could we to have a pretty minimal Smalltalk/Pharo powered shell language/mini-image that can execute .st scripts (like with Coral and Scale) and launch a notebook, being it native (like Lepiter, with its wonderful one single rendering tree, but more minimalist and with async snippets/code execution by default) or web UI (still to be created, maybe with HTMX)? My approach, for the moment, is to develop MiniDocs[4] to provide support for minimalist documentation tools (starting with Markdeep and some Pandoc support) and some notebook web rendering (via Zinc) and export. Pandoc's Markdown export with metadata to make notebooks collaborative (as we are doing with Markdeep) is yet to be done (but soon in the radar). Also Brea[5] will be (slowly) used/revied to explore building web sites/interfaces (now that HTMX is available to avoid JS) Still, the question of how minimal Pharo or GT can be made to run from shell or integrate with external software ecosystems is an open question for me. Seems that the best approach would be to revive Scale (or Coral) and to see which minimal elements of a computational notebook experience can be bootstrapped from there and which lessons from more (b)loaded environments can we port to such minimal systems, while still interop with the wider Pharo ecosystem or even with other languages (like Nim or Julia). Maybe PharoIoT or other minimalist images could be a starting point also (but pharoiot.org seems also unmaintained). I'll keep the community posted on the experiments sketched above. Cheers, happy new year and thanks for the Pharo community, ecosystem and all the hard work and good vibe behind.

[ANN] success story: ApptiveGrid

by Norbert Hartl

I wanted to write this for a very long time nowâ¦so finallyâ¦Iâm very proud to announce a new success story: ApptiveGrid ApptiveGrid is a SaaS tool to digitalize and automatize business processes. On the one hand ApptiveGrid is visual database that enables you to model your database via web frontend. At the same time this model is available via REST API. On top of the data model a form creator turns your model into a form that you can send e.g. via email to inquire data from other peopleâ¦ On the other hand ApptiveGrid is a workflow system where you can define your work flow in the web frontend and connect to events. These events are either internal (resulting from a change in your data model) or external where you can use web hooks to kick of work flows. With the combination of both parts ApptiveGrid is able to solve many of modern digital workflows. It enables to make it for low cost and in almost no time which are two pretty good reasons to use it. If you want to use it just visit: http://www.apptivegrid.de. ApptiveGrid provides a start plan at no cost where most of the functionalities are available. If you have additional needs just write me. For the people in the pharo community Iâm sure we can provide a bit more on top. About the tech stack: - The business backend of ApptiveGrid is 100% pharo - It uses https://github.com/svenvc/zinc components for the HTTP frontend - and https://github.com/ApptiveGrid/Soil as the persistence solution. - Each user has its own database (an empty soil database is 24kb on disk, could be made even approx. 5kb). There are over 3100 databases in the system right now - one pharo image holds multiple soil databases open and provides memory caching for the objects - routing of requests is done with haproxy connection persistence - the web frontend is made with Vue.js and a pharo library that we transpile to JS with PharoJS If you are interested you can also watch my ESUG videos at https://www.youtube.com/@esugboard. All talks in the last 2 years were about ApptiveGrid If you have question, donât hesitate to ask, Iâm happy to answer! Norbert

Re: How to open files in the underlying OS

@John: That solves the problem, in fact. Many thanks. I'm a bit ashamed that I couldn't find such a simple solution.

Re: How to open files in the underlying OS

by John Aspinall

Hi Rui - on my system (Windows 10, Pharo 11 with Pharo-OS-Windows package) both of the following work fine: WinShell shellOpen: 'd:\temp\test audio.mp3â. WinShell shellOpen: 'd:/temp/test audio.mp3â. Evaluating either one from a Playground opens the mp3 file with the registered app (VLC in this case). WinExplorer explore: does nothing when passed a filename, but with just a pathname (e.g. âd:/tempâ) opens a Windows Explorer on that path Hope this helps?

A kind of database for a sound library. It has only 2 classes: SoundRecording and SoundLibrary. And a few presenters. SoundLibrary holds <recordings> (aSet), <tags> (aSet) and <directory> (aFileReference, which allows the library folder to be movable). A SoundRecording holds a bunch of properties needed for professional information and editing on sound files, plus an <address> (a relative FileReference), which is the central piece for identifying each recording/file. There is some automatic methods, including a scanner to search for files in the library and automatically create SoundRecording objects from each file found.
