Pharo 7.0 released

Here is a link to Python's docs(https://docs.python.org/3/). It's still a little busy, but you can go a long way just by using the Python Tutorial (helpfully subtitled with 'start here') followed by the full Library Reference. A lot of people rave about how great Python is and how popular it's become, but I think one of the unsung heroes of Python's success has been the great documentation.

A (fairly) recent language that appears to have taken a page from Python's documentation success is Google Go. Here's the Go Docs:(https://golang.org/doc/) Take a look at that page. It describes Go, then tells you how to install it, then provides a pretty good tutorial (called a Tour of Go), and then provides a really comprehensive Reference Manual that tells you the various libraries Go ships with, which includes a hyperlink that reveals documentation for each library, and if you explore the linked page and click on a function, that's also a hyperlink that takes you to the actual code for that function so you can read the source code--itself is written in Go. Basically, it's easy to see how Go works, find out what libraries it includes, read good docs for each library, and even explore the library's implementation.

Continuing my argument, I would propose that many of the widely adopted languages of today aren't just good languages, but also benefitted from really good documentation. K&R is still famous, even though the last edition came out in 1989. Here's an interesting question: does C become such a big hit without the fantastic books it had? In the pre-WorldWideWeb universe in which C came to fruition, great books were critical. I would argue no. I believe it's documentation was a critical element of its success.

I think Perl has a similar story. Yes, it was powerful and useful and that was a big feather in its cap, but it also had amazing documentation in the form of books(Camel Book, Llama Book, O'Reilly Perl books in general) and man pages. It's easy to forget--and some don't even know about--the amazing man pages that Perl enjoyed. Here's a hyperlink to Perl's Man Pages table of contents: (http://perldoc.perl.org/perl.html) They are awesome! For example, check out the Perl regex tutorial man page: (http://perldoc.perl.org/perlretut.html) To this day, that's still probably the best explanation of regexes out there. And if that's too much, you can read Perl's quick and dirty regexes man page instead:(http://perldoc.perl.org/perlrequick.html) There's man pages for so much in Perl it's ridiculous.

(Rough waters ahead...)

Now back to your first question about Pharo's current docs. Here was my experience...

I checked out the links you posted. After a few clicks, I got a page with a bunch of pictures that looked like books. I'm wasn't sure what book I should pick, but "Pharo By Example," seemed promising. I clicked on it and discovered it's a PDF--not the preferred format for the web--that tells me the current version of Pharo is still Pharo 5. So I'm already worried because the book is out of date.

OK, I move forward to page 16 before I get to hello world. That's not too bad for a book, but slower than lots of web based tutorials, which is the real competition for "Pharo By Example" since I'm reading it on the web. Page after page then scroll by about Pharo the IDE, but not Pharo the language, which is what I'm really trying to learn about. Finally, on page 28, the book says we get to learn how to define a method, which is apparently how we do anything in Pharo, but then we crash to a stop and write a test first! Then we move forward again until we, at last, get our second piece of code: shout ^ self asUppercase,'!'

That extremely short method doesn't arrive until page 31.

Next we move to Chapter 3 and make a GUI game called LightsOut, which sounds cool, but it's like drinking from a fire hose because none of the syntax or libraries have been explained yet. (Note: At this point, I don't feel like I could run with this example to make games of my own.) If you survive Chapter 3, which is doubtful, and make it to Chapter 4 on page 59, the book finally explains Smalltalk syntax, though even this seems a bit jumbled since the real discussion of message syntax, which is at the core of Smalltalk syntax, is pushed back to Chapter 5 for some reason. Control structures are discussed in Chapter 4 instead. To put that into perspective, there's a mention of blocks serving as lexical closures in Chapter 4 before we really find out how basic messages work in Chapter 5.

By the end of Chapter 6, we've covered the Smalltalk object model and I still have no idea how to actually make a program! At least, I don't think I do.

To put it bluntly, "Pharo By Example" isn't a good programming book. Yes, I recognize it's a labor of love. Yes, I recognize that it's being given away for free. Yes, it took time to write. That's all noble. But it doesn't change the basic, ugly fact: "Pharo By Example" fails to get the job done.

At this point, I'm not at all confident that I will be able to program in Smalltalk after reading this book. More importantly, the book hasn't provided any real reason to become a Smalltalk programmer. It all looks a lot like IDE customization and tools for a language that doesn't seem to run anywhere except in the IDE itself. As an emacs user, I've already got one of those... :)

Seriously, I think some real thought needs to be put into explaining (1) why anyone would benefit from Smalltalk instead of more mainstream language and (2) how to showcase Smalltalk's strengths without getting lost in the weeds of the IDE.

Here's the curriculum that I suggest: (1) tell us how to download, install, and run Pharo (2) demonstrate how to build a few old school IO games--HiLO, Hammurapi, Trek, etc...--so we see how you can do IO. Along the way, introduce Pharo's syntax (3) give a full, long-winded, boring as hell discussion combining and improving upon Chapters 4-6 where you admit up front that it's going to be boring as hell and then (4) go back to saving stuff to Github and distributing the software. (5) explore the various parts of the IDE in independent chapters while providing real examples of how those features make our lives better. (6) go back and provide an entire section of webpages explaining, in great detail, the Morphic stuff that just gets a passing glance in the book for that LightsOut game. It really looks like there's something there, but who knows. That little chapter on Morphic in the back of the book doesn't remotely cut it. (7) provide separate chapters on important libraries? that Pharo comes bundled with--the kind of libraries that all modern languages take for granted and expect. (8) provide some real-world, well-commented, Pharo programs for us to dissect so we can see what they look like. For most languages, I can just download a few open source projects and read code until I'm sick of it. Does that even exist for Pharo?

Let me say again that I honestly think Pharo looks amazing. I really want to know how to make something in it, but I'm not sure I ever will because the amount of effort I'm describing is huge. I hope it happens though.

Finally, I recognize that my feedback was critical. I sincerely hope that you take it as constructive criticism rather than as an attempt to insult. The last thing I'm trying to do is insult anyone.

Pharo might be the first project I've seen whose actual usability an user-friendliness is behind that of their presentation :)

There's a book, "On to Smalltalk" that actually did a decent job of getting you started, but it's decades out of date now.
