[Pharo-users] Permancy of booklet links

[Ben Coman]

This link turned up in a google search on... Web Scraping Pharo, which is
great,

http://files.pharo.org/books-pdfs/booklet-Scraping/2017-09-29-scrapingbook.pdf
but with the date I'm wondering how permanent the link is, for if I use it
the respond to someone's question in a forum?

Will you be keeping years of pdfs?
For now I'll just use the directory url, but future missing files will
frustrate user searches.

Perhaps a sitemap is needed (though I'm not familiar with the details)...

Re: [Pharo-users] Pharo: Reinventing Smalltalk

[Andrew Glynn]

There is a basic difference between debugging compiled code using debug 
symbols, debugging a live environment that’s represented as if it isn’t,  and 
debugging a live environment that’s represented as if it is. 

In general Java is represented the same way as C/C++, although Eclipse is 
somewhat better than other Java IDE’s when it comes to debugging, mainly 
because it tries to be somewhat like VisualAge for Java, which was written in 
Smalltalk.

XCode represents MacOS similarly to the way Eclipse represents Java.   
F-Script, on the other hand, allows you to debug MacOS / iOS in the same manner 
Smalltalk environments do.

But then, F-Script is Smalltalk by any other name.

Should pretty standard even for Java using a debugger 

I mean I have done this with Visual Studio and its debugger with C++. It even 
allows you to inspect the machine code or see the memory in raw bits formats. 
So I find it hard to believe that Eclipse cannot do that with Java.

There is even a feature which is called watching a variable that pops the 
debugger only when a specific variable changes value. The functionality is 
there , the terminology is different.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

[Dimitris Chloupis]

Well if you have a specific template in mind then you can use Pillar and
input the final results as images back to Morphic.

Creating a full PowerPoint implementation with Morphic sounds an overkill
to me. Why waste all this time when there so many great external solutions
?

Or you even bypass Pillar and go straight to a PowerPoint app, export to
jpgs and import to Morphic. Definetly not more than 2 hours work. If you
love open source LibreOffice has an excellent presentation app

Re: [Pharo-users] Pharo: Reinventing Smalltalk

[henry]

Watching is one thing you can do to see the result of an expression. The issue 
is that this has to be in scope within the selected stackframe or something. I 
can never watch once that scope has gone. As a result, I have no idea if it is 
possible, but I cannot just open an inspector that sticks around as I process 
stacks in the debugger. That level of the environment being alive is just 
missing from the Java development environments. One reason is Smalltalk is 
running the image objects all the time and Java does not have an image-based 
environment. You restart the environment each time you rerun a java test case. 
It's DOA.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

[Tim Mackinnon]

Yes I was thinking of something like the morphic approach with a palette for 
adding buttons, text, images (maybe someone has done a simple vector paint app 
- didn't think to check).

Of course it quickly gets annoying without a simple template mechanism to have 
a consistent header/footer - and you also need to try it on a projector and 
make sure it actually looks right... and so it will take longer than a few 
hours is my fear (my morphic is a bit rusty too).

Not a horrible amount of work - but I actually need to create my slides and 
demo so may be a longer term project unless someone has already done it.

I am only familiar with Eclipse, not other Java development environments. In 
comparison, what is lacking in the land of Java, which is so powerful in 
Pharo/Squeak/Smalltalk is the ability to inspect the object resulting from some

Super cool more detailed recommendations when I try it on practice

A cheap pdf viewer in Pharo would be to turn pdf pages to JPG images which
you can load via image morph so you won’t have to have two separate
windows. There are ton of converters out there that can do this.

[Pharo-users] LiteratureResearcher - where graphs, PDFs, and BibTex happily live together

[Manuel Leuenberger]

Hi everyone,

I was experimenting in the last few weeks with my take on literature research. 
For me, the corpus of scientific papers form an interconnected graph, not those 
plain lists and tables we keep in our bibliographies. So, here is the first 
prototype that has Google Scholar integration for search, can fetch PDFs from 
IEEE and ACM, extracts metadata from PDFs - all this results in hyperlinked 
PDFs!

See a demo here: https://youtu.be/EcK3Pt_WnEw 
Also slides from the SCG seminar here: 
http://scg.unibe.ch/download/softwarecomposition/2017-10-31-Leuenberger-ILE.pdf 


I plan on packaging it, so that those who are interested can check it out 
themselves (help wanted!). Currently, it only works on macOS.

What do you think of my approach? Which use cases should be added?

Cheers,
Manuel

Pillar supports embedding LaTex and HTML inside your pillar files so
whatever works for those should work for Pillar. Pillar also has templates
you can modify via moustache. Pillar is actually so flexible I used as a

a charm. It’s syntax is just the tip of the iceberg.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

[Dimitris Chloupis]

Well technically this is easy to do with Morphic. Probably Spec 2. Doing it
from inside the Pharo window will give you the ability to demonstrate live
code and Morphic is live code.

If you don’t want to do everything with Morphic you can create this in any
app of your choosing , export to images and have Morphic load those images.
I don’t see why this would take more than a couple of hours to prepare ,
the actual Morphic code should not take more than 20 minutes.

It a simple case of a SystemWindowMorph embedding a couple of button morph
(for going forward and backward) and an ImageMorph. Plus a timer if you
want the slides to proceed automatically.

If you feel adventurous you can do this entirely on Morphic , again should
not take you more than two hours total together with content creation.
TextMorph should be more than enough.

I would have said use Pillar but in this case it’s an overkill and Pillar
does not allow for the precise positioning of images like Morphic does.

When creating PDF document with pandoc command line I use the
parameter "--toc" to automatically create Table of Contents from the
document titles and subtitles. For example from command line:

pandoc --toc --latex-engine=xelatex --listings -H macros.tex
BioSmalltalk.md -s -o BioSmalltalk.pdf

I don't know if "toc" is supported in Pillar. As I understand a Pillar
book can contain multiple chapters, but a chapter may include a table
of contents on its own?

>> For tables I use tabu, longtable, booktabs, what to use in Pillar?
> In pillar you have

> | a column | a column |

Ok, what I mean is for example with the "longtabu" LaTeX package I can
specify column width individually:

\begin{longtabu} to \linewidth{X[1.5,l,m] X[.3,m] X[.3,m] X[.5,m]
X[c,m] X[c,m] X[c,m]}

And many other table spacing properties :
https://en.wikibooks.org/wiki/LaTeX/Tables

I guess to add more advanced features one should edit Pillar templates
with archetype?

I would love to have linkcolor, anchorcolor, citecolor, etc :)

What I found is
https://github.com/pillar-markup/Pillar-Archetype/blob/master/book/support/latex/common.tex

So I could inject my own LaTeX styles/commands/sections in common.tex?
Or should I go through PRLaTeXWriter?

Then if you like it you may integrate into Pillar in the future?

[Pharo-users] Writing "powerpoint" like presentations in Pharo?

[Tim Mackinnon]

Hi - has anyone made anything where you can create a full screen presentation 
in Pharo with slides with some large text, bullet points and embedded pictures 
- but then it’s a facade that lets you evaluate items in the slide or jump to 
any code mentioned?

Sort of like what Alan Kay does in the eToys images?

I need to do a presentation next week and I always loved it when I was fooled 
into thinking I was looking at a static’ish powerpoint and then suddenly 
realised it was a live environment.

It doesn’t sound that hard to do something simple - but I’m not sure if I can 
pull it off in time for my presentation. But am curious if we have something.

(For bonus points, GT-Spotter stuff would work in it over top of the 
presentation to demonstrate simple things)

Re: [Pharo-users] New Pharo Booklet

[Renaud de Villemeur]

Hi Stephane

Your booklet is very usefull, and show stuff that can only be done by code.

However, in your example, you show how to change syntax style, or enable
freetype, which can also be done using the setting framework, so I was
wondering, how would you position Startup Loader with the settings
framework ?

Next, you always use StartupLoader. In my recent Pharo 6.1 image, this
seems to be replaced by class  StartupPreferencesLoader. Not a big deal, I
was able to find the correct class through the message, but quite confusing
if you only read the booklet.

I tend to use raw image, and load everything from scratch, instead of
keeping multiple image around. So I try to clean things, or put things
automatically at startup

How to remove automatically at startup the welcome windows (probably
specific to Pharo 6)
World submorphs
  select: [ :sm | sm isSystemWindow and: [ sm label = ((Character value: 0)
asString, 'Welcome')]]
  thenDo: [ :window | window delete ].
]

Open browser automatically on package specific to my (little) projects
|browser|
browser := Smalltalk tools openClassBrowser.
browser open.
browser ui packageSearchUpdate: 'MyPack'

Cheers
Renaud

The voice in the background behaved differetly with different players on
windows 10
- in "Films and TV"  and "VLC player" it comes unltil you manually switch
the audio channel (it shows 2 audio channels)
- In Media player it works fine though i could not find 2 audio channels

Good!
now I would start simple in plain pillar and avoid as much as possible
to use specific latex function
and see if this is really a problem and then we can see if we need to
extend the latex template or pillar.

Pillar is not latex. We want to keep agnostic about latex.
