Traditionally Pharo could only create standalone applications, but the minheadless builds are making good progress on stripping the windowing code to facilitate it being embeddable.

A platform specific VM runs on Windows, Linux, OSX. All those VMs run a single application binary.

GToolkit is also an exciting new development that's happening in parallel with the mainline Pharo. This is a reimagined programming workflow for Smalltalk with new UIs for coding, debugging, documenting, example browsing, testing, etc. Likely the best bits of this environment will be cherry-picked into future Pharo releases, but meanwhile it is available here at https://gtoolkit.com/ and I for one am building an appl…

Are there any screencasts or similar videos out there? Looks promising but it probably "clicks" more if you see it in action with a more complete example.

I'd recommend downloading and starting it. It opens into an interactive "notebook-like" tutorial. The system is very discoverable. Has a markdown-like syntax where you can embed Smalltalk objects and code examples and interact with them directly in the page.

The Pharo website has zero mention of its relation to Smalltalk, although the Wiki article calls it a dialect. So how close are the two in reality? Is the syntax from your standard Smalltalk-80 textbook largely portable/compatible to Pharo, or is Pharo merely "inspired" by Smalltalk?

Squeak is directly descended from ST-80. Ten years ago Pharo forked from Squeak due to conflict around adding features outside the ANSI standard. Pharo wanted to distinguish itself from Smalltalk to avoid constraint by the standard so minimises mention of it. But Essentially Pharo is Smalltalk plus...

> Pharo is the most actively developed and used Smalltalk environment. Is that true? VisualWorks isn't used more places? Where are you getting that information from?

One of the key words in that statement was "actively developed". Cincom, Instantiations, and GemTalk have some great people working on them, but Pharo7 had 75 different people contributing - including probably almost as many full-time people as the commercial developers (maybe more).

I love Pharo, so don't take this as me trying to take anything away. Cincom "actively develops" VW as well. I keep in touch with that side just for my own information. Pharo is doing a phenomenal job.

I looked for any useful documentation for a few minutes and just gave up. I don't want to read a book. I don't want to watch a video. This is not my first programming language, thank you. I just want a "hello world" example to get an idea what I am actually dealing with. How do I run a "hello world" program from the command line? How can I deploy that to another machine that doesn't necessarily have a GUI?

As a beginner, ProStef (Mini tutorial) helped me get familiar with environment. To access that tutorial, it's on the welcome page in the Learn Pharo tab when you first launch the image. Hope that helps!

For what it's worth I think these are decent questions to ask, even if others think they're worthy of a downvote. As far as I understand it: it doesn't necessarily compile in that sense. You are constructing an 'image', which is basically a living environment that your program runs in, and maybe it corresponds somewhat to a VM. But you're not really treating the code that the VM runs as separate to the VM itself. In…

Smalltalk system consists of a VirtualMachine and an image. An image is just some Smalltalk code compiled into a form suitable for VM to read it into memory. The initial image contains all the standard classes of Smalltalk plus the GUI and various tools. When you add a method to some class inside the GUI, it gets compiled and added to the image held by the VM in memory. Later, you can dump the modified image to disk,…

Some/many Common Lisp implementations. But there are a bunch of Common Lisp implementations which are not image-based.

Another difference might be that most image-based Common Lisp implementations don't use portable byte-code. Some are using byte-code engines, but those are usually not portable across operating systems and/or machine architectures.

Pharo does have commandline functionality, but that won't demonstrate its value as a first experience. For an interactive tutorial... open Pharo, then left-click background, Tools > Playground, type & highlight 'ProStef go', right-click & 'do it'. Then try these one-liners in the Playground... https://medium.com/concerning-pharo/elegant-pharo-code-bb590... . Then (and I know its a video) but maybe serverless PharoLam…

Do you understand that you are not answering `virtualized`s question?

The question is not about a Pharo commandline that exists as part of the Pharo GUI.

The question is about an OS commandline like "GNOME Terminal" with stdio.

> I just want a "hello world" example to get an idea what I am actually dealing with. How do I run a "hello world" program from the command line? The trouble is that what you are dealing with is a graphical interactive programming environment. Sure, you can run it from the command line like /bin/perl, but to understand what you are dealing with you have to open it up and try it on its own terms. If you aren't interes…

Perhaps they are interested in using a novel immersive programming environment to develop an app that runs from OS command line without GUI.
