I completely agree - dark mode is great for content that you want to

You assume wrong cause dark themes have been dominating GUIs for over 
3 decades now.
Not really; bright on dark was only dominant in the days of the CRT 
terminal when there were no "themes".  (Even if you could do it as a 
hardware switch, setting, say, a VT220 to black-on-white both looked 
terrible as it was more an uneven gray, and tended to dim  the tube more 
quickly by burning in the background.)


Instead, since full bitmap graphics happened, all screen interfaces back 
to Xerox's prototype office systems, then Lisa/Macintosh, and then 
Windows 2.1 have been using dark type on a white background for text 
work.  Partly this was because of the original office metaphor, but 
partly also because it was shown that it was easier (meaning, less error 
prone) to read.


Here's a study that showed that participants were 26% more accurate in 
reading text that way (note that "contrast reversal" on displays in 
those days meant dark characters on white background):


Bauer, D., & Cavonius, C., R. (1980). Improving the legibility of visual 
display units through contrast reversal.
In E. Grandjean, E. Vigliani (Eds.),  Ergonomic Aspects of Visual 
Display Terminals (pp. 137-142).

London: Taylor & Francis

There were other studies in the 1980s that didn't report lower errors 
but instead faster reading with black on white. Academically, the 
matter's pretty much considered settled - black on white is better for 
most of the population, and that's on screen, not on paper. (You can 
substitute any degree of light or creamy for the white, that's really a 
variation of screen quality.)


The engineering workstations of the late 80s and 90s (Sun etc) used 
black and white as the application default as well, with white on black 
limited to console/shell windows. This was partly for consistency with 
the old style, partly for easy contrast with application windows in a 
multi-window environment.


Pharo was the rare exception of using a white theme. Light themes may 
be popular but white are definitely not. The web is the last fort of 
bright themes, but the web was and still is eons behind when it comes 
to matters of UI.
Most other Smalltalks are dark-on-light by default all the way back to 
Smalltalk-80 out of Xerox PARC.  None of this had anything to do with 
the Web, which came after, but which obviously also profits from the 
same increase in readability.  Rather than behind, Smalltalk was ahead 
and the rest of the world followed.


The dark theme as default in Pharo I personally consider a step back. As 
someone who's been busy for 25+ years defending use of Smalltalk for 
real applications, a return to a primarily developer-cool presentation 
instead of a user-oriented default is IMO not a plus for a language 
branch that was billed as more industry-oriented (which IMO is not 
exactly the same as developer-oriented).  But I also understand the 
desire to attract developers with the look that's currently fashionable.


That said, I wonder if the recent preference for dark among developers 
(not Pharo-specific, but many languages) has to do with the rise of 
widespread code highlighting. I could see how colour highlighting shows 
up better on a dark background than being glared over by a white one.

[Pharo-users] CodeImporter. 256 literals limit

[Andreas Sunardi]

I have written a tool (Pharo5) where user gives an input file to it, where
the content is a smalltalk code, a DSL. I used a subclass of CodeImporter
class to evaluate this input file.

Recently my user used an input file where it hit the 256 literal limit
(total of unique string, number, method name, etc), down in
OpalEncoderForV3PlusClosures >> genPushLiteral:. The number seems to be
hard coded and related to byte code generator, not something I can simply
increase. I wasn't aware of this limitation.

Before I overhaul my tool, I thought I should ask. Is there another
alternative to evaluate a smalltalk file/script? The file is small, 27k,
but the number of unique literals in it is > 256. Is it possible at all,
seeing that the limit is related to byte code generator.

Thank you in advance

Re: [Pharo-users] Code mystery

[Dimitris Chloupis]

You are not going crazy that's an ugly method. Probably the author intended
to use dir and the forgot about it and instead hard coded the dir path
inside a class method. A mistake that can happen to anyone.

The method will have to be updated anyway because name is to be removed, so
it won't work.

As always too much code too few people. If you think that's bad embrace
yourself if you try to read Morphic code. Huge suffering for me when I
tried to learn how the task bar works and apparently using it wrong it
freezes the image.

Tons of Pharo code needs a clean but needs also a lot more people.

[Pharo-users] Code mystery

[PBKResearch]

Hello All

 

Following the discussion on dark mode, I was browsing the code on themes (in
Moose 6.1 = Pharo 6.0, Latest update: #60486). In Class ThemeIcons, I found
this method:

 

downloadTo: dir

   | zipArchive |

   

   zipArchive := self class destinationPath / (self name,
'.zip').

   zipArchive exists 

  ifFalse: [ 

 ZnClient new

url: self url;

downloadTo:
zipArchive ].

 

   ^ zipArchive

 

The mystery is that the argument dir is not referred to anywhere in the
code. It probably works, because the only invocation of the method is from
ThemeIcons>>downloadFromUrl, which sets the argument from self class
destinationPath, and the code above recreates this as the path to
zipArchive.

 

I thought I understood Smalltalk coding fairly well, but this really puzzles
me. Why would anyone code like this? Shouldn't it be picked up by a code
critic? Or am I going crazy?

 

Any help gratefully received

A super-simple-GUI in a minimal image step could later provide Emergency
Tools facilities, so would not be redundant code (I've not been much
successful using the current Emergency Evaluator.)
Perhaps even a REPL like interface.  Editing could be done in an external
editor and pasted into the REPL in this form... .
SomeClass>>#someMethod
self doStuff.

Are Bloc and Brick going to be loadable separately?
How big is Bloc on its own?  Would it (or some core subset of it) form a
good basis for new Emergency Tools, or should they completely separate?
A decision tree might be useful to see the overlap of different design
options here showing the size of each bootstrap step.

Re: [Pharo-users] constraining dragging movement of Morph Windows

[H. Hirzel]

Hello Peter

A hint, but not yet the solution

 World griddingOnOff.

toggles the grid for morphs.


  World setGridSpec.

Allows to set the grid.


   World griddingOn

tells if the grid is on or off

The commands above affect morphs,

Morph new openInWorld


but not the windows (Nautilus, Playground, ..., SystemWindow, ...)


Something else in addition seems to be needed ..

 The fact that did change was that high cholesterol is bad, some doctors

 based on a research that was on a very small group of subjects and if I am
 not mistaken it was not even humans it was lab rats.

 The problem none really funded a serious research for this fact and
 when they did they discovered that indeed eggs and other food do raise
 cholesterol significantly but our liver is capable of reducing the
 production of cholesterol to compensate hence its nowhere near as harmful
 as they used to assume.

 Science is flawed mainly because finding small facts is easy and cheap
 but general fact are very complex and very very expensive.

 Like all things, you get what you are paying for. This is why you see
 and hear so many contradictory facts. They are mostly based on simple cheap
 research. Plus "fact" is purely a fantasy, our world is too complex for
 facts as most people define them. There is truth sure, but not as easy to
 consume and explain as we would wish.

 The preference to light and dark themes is not product of bad
 scientific research. I suspect the reasons are too complex for science
 anyway because we are even eons away from explaining the human brain and
 how it works.

 Pharo not only allow you to choose a theme but its theme classes are
 actually very easy to use which is something it inherit from Squeak. It
 took me a day to create my own theme.

 The Dark UI theme class is excellent example

Re: [Pharo-users] Dark Mode

[Dimitris Chloupis]

Actually what you say makes no sense to me because my monitor is already at
bare minimum. Its not the intensity, its the contrast. The problem
obviously is not an exposure of 30 minutes. The mail I am writing now  has
a white background. But its not a problem because I spent an 1 hour tops
with email total time. I would like if Gmail had a dark theme but its no
big deal.  However when one spent more than 8 hours it becomes a problem.

It was the same when I was studying in UK law. I was very used into reading
english because the vast majority of the coding books I had bought and
reading since I was 13 years old were in english. It was not a problem
reading for an hour, but after 5 hours both my eyes and brain were tired.
Its that extra effort that accumulates hour by hour and the more time you
spent, the more obvious it becomes. 5 hours reading a book in my mother
tongue is like night and day.

So  when I was spending a lot of hours working with Pharo the white them
did became a major problem for me. Its not as if I see a light theme and
after a few minutes I scream in pain "Oh my eyes are burning" :D

[Pharo-users] constraining dragging movement of Morph Windows

[Peter Uhnák]

Hi,

is it possible to somehow "constraint" the movement of windows (Nautilus,
Playground, ..., SystemWindow, ...)?

E.g. I want for them to only move (or "snap") only at steps of e.g. 20
pixels.

So sort of snap-to-20-pixel-grid behavior.

Thanks,
Peter

Hi Phil,

Yes, I wrote a FIT file parser. FIT is used to store “scientific” images, in

They are mentioned at the end of the readme, and placed under the "Utility"

Re: [Pharo-users] Metalinks UI... ?

[Peter Uhnák]

Maybe this? https://github.com/peteruhnak/metalinks-toolkit
It also enables/adds the browser icons.

However, the toolkit was more towards preserving the metalinks when a
method changed... anyway, it is document.

In metalink-wrapper branch there are also two undocumented classes
simplifying a bit the usage of metalinks, but I forgot to merge it and
document it... so. :)

Re: [Pharo-users] Dark Mode

[Richard Sargent]

On the history of screens and light versus dark...
[The TL;DR answer is "technological limitations of the era."]

Way back, in the days when Smalltalk was but a gleam in its fathers' eyes,
we had CRT technology. You know, magnetic coils sweeping a beam of electrons
across a phosphor coated glass surface to make the phosphor glow and present
images to people on the other side of the glass. There were two common forms
of this device: computer terminals and televisions. There wasn't a lot of
difference between the two.

Back in those days, the electron beam hitting the phosphor typically caused
a lot of "blooming" in terms of how much illumination occurred. In other
words, when writing green text on black, the pixels of phosphor glowed
brighter and spread out a bit into the surrounding black. Inverse video
text, on the other hand, showed a green or white background with black text
(the absence of electrons hitting the phosphor). The bloom from the
background squeezed in to the letter space and made letters much harder to
read.

Back in the 60s and 70s, computer screens tended to support 80x24 (or 25)
lines of text. 80 because that was the width of a Hollerith punched card, of
course. Graphics? Almost unheard of. There were efforts like Sketchpad
[Sutherland, and probably et al.]. Graphics didn't make much of an
appearance until the mid-70s with the early personal computers, most notably
the Apple II. The earlier Radio Shack TRS-80 was purely character oriented,
and the Exidy Sorcerer was character oriented but allowed one to
programmatically define the glyphs used for the character set (which allowed
a limited form of graphics).

Those early PCs utilized existing screen technology for their displays. By
"existing", I mean televisions. The RF (radio frequency) conversion and the
sloppy/low resolution of TVs at that time still left one with a greatly
limited display capability.

The first IBM PCs came with a CGA resolution video adapter. You can look up
the details. It was limited, to say the least.

About this time, the market for specialized monitors took off and the use of
TVs as monitors started to dwindle. Coincident with this, the computer
graphics market took off and the specialized monitors / resolution race
began.

With higher and higher resolution and better electronics, the phosphor bloom
effect was correspondingly reduced. And of course, with solid state
displays, the bloom effect disappeared entirely. (It's hard to have that
bloom when there is no phosphor and no electron beam sweeping over it.)


Coincident with the introduction of bitmapped graphics (the Smalltalk
machines, things like the envisioned Dynabook, and so on) created the
opportunity to have displays that mimicked the way we worked outside the
computer world. i.e. dark text on white paper.

Re: [Pharo-users] Metalinks UI... ?

[Steven Costiou]

Yes there are the suggestions, but they provide already configured
metalinks. I am much more looking for a ui - even very basic - which
allows to configure a metalink options (target node, metaobject,
selector, etc.). 

How can i enable the browser iconswe can see in your images for my own
metalinks ?

Re: [Pharo-users] [Pillar] How do I include a picture which I get from aMorph imageFrom?

[H. Hirzel]

The answer (second option by writing the image to disk) is

| myMorph myForm myPillarSource myPillarDOM |

myMorph := AlignmentMorph newRow
   addMorph: (EllipseMorph new color: Color red);
   addMorph: (EllipseMorph new color: Color yellow);
   addMorph: (EllipseMorph new color: Color green);
   openInWorld.

myForm := myMorph imageForm.
myMorph delete.

PNGReadWriter
putForm: myForm
onFileNamed: 'myImage.png'.



myPillarSource := '

There is also `Morph cycleHalosBothDirections: true.` to re-enable non-Shift
(i.e. bidirectional) cycling a la Squeak

[Pharo-users] Udo, an issue with the stable version - Re: Validate password with PBKDF2

[Francis via Pharo-users]

--- Begin Message ---
Hi Udo,

I've just downloaded your PBKDF2, but unfortunateley loading the stable
version
(Smalltalk at: #ConfigurationOfPBKDF2) project stableVersion load

makes the SHA256 class disappear.



So I reverted to a previous image and I loaded another version:
((Smalltalk at: #ConfigurationOfPBKDF2) project version: '0.0.5' ) load.

I think there is something weird in the stable version.
Cheers
Francis

Re: [Pharo-users] Pharo 6.0 and 6.1 64 bit freeze on MacMini

[Dimitris Chloupis]

You can use Pharo to make iOS apps .

Is it a good idea ?

Don't know but the author of Dr Geo can jump in here and advise you. he is
the one that released Dr Geo for iOS. I think it's Android that is a bit
more problematic.

Your freeze is indeed weird but when it comes to MacOS , it seems I am the
weird. The website advises that in Sierra Pharo 6.1 cannot work outside the
Application folder, it works for me.

I agree that hunting bugs , especially lower level requires a level
masochism :D

The easiest solution is to make sure the bug is outside Pharo. Maybe it's a
driver , MacOS is prone to these kind of problems. My first Mac was
crashing all my graphics orientated apps for 2 weeks after I bought it .
After second week Apple updated the GOU drivers I experienced crashes of
two or three per year. So do a thorough search if you have not done already
, there is always a smarter guy with a work around.

I am actually in the process of making a commercial Python app and wonder
whether I should put Pharo into the mix.

It's very tempting.

I am a huge fan of the bootstrap project and of course it goes far beyond
the GUI. For me it's No1 in my list of my favorite new features for Pharo.

I am pretty sure it will also eliminate a ton of spaghetti code and make
the image far easier to understand.

Hi, 

i think somebody told me (i do not remember who) that an other somebody
(whose name i don't remember either) made a very basic UI for metalink
creation or management. Would somebody know of such project and where to
find it ? 

Thanks,

Hi Stephane, Ben

In the Smalltalk world, you could value me as a relatively "simple"
application developer  as a first attempt after a long time, I am trying to
make 
a dentist's app with Pharo Smalltalk.  
(The intend is to use Smalltalk (Pharo) with Seaside and Postgress whenever
possible,
because today, Smalltalk is fast enough for most applications)

At deeper levels, like working or even adequately understanding the inner
workings of VMs
I virtually have no knowledge. This is not my terrain. Although this might
be interesting too,
 it would cost me weeks to get into that, before being able to do things
like debugging VM's...
 
So also due to time constraints , I'd have to refrain from that, sorry, 
also because I am currently working on a new version of my app RavelNotes. 
This is in Swift ( i can live with that) btw, because Smalltalk is not
available 
for making  native apps for iOS iPad. Would be an extremely daunting task 
to link all iOS libs etc into Smalltalk... 



cheers TedvG

Understood. I think it may have an overall huge benefit by making the
system far more modular once done. But maybe, for it to work effectively,
one needs to have a usable minimal image with the GUI and very simple core
tools.

Sorry, I cannot. We are still not in the state where is possible to

Re: [Pharo-users] How to create a minimal image ?

[Pavel Krivanek]

It is not that simple. The baseline expects that you will have a pharo
repository clone in a folder named 'pharo-core' in your working directory.
Then you need data  like files or icons.

set -e
wget http://files.pharo.org/sources/PharoV60.sources
unzip pharo-core/resources/fonts/BitmapDejaVuSans.fuel -d .
mkdir icon-packs
cd icon-packs
wget http://github.com/pharo-project/pharo-icon-packs/archive/idea11.zip
cd ..
pharo Pharo7.0-metacello-32bit-82ecd43.image --no-default-preferences eval
--save "Metacello new baseline: 'UI';repository:
'filetree://pharo-core/src'; load"

Unfortunatelly the resultant image is not usable - it immediately falls
into the emergency evaluator - because of the dependencies on translation
and fast table. We need to provide some care to it again because it is not
generated regularly -> it gets quickly broken.

You can eat eggs all you want provided you burn the calories. They are
shock full of amino acids.

Cholesterol is a precursor of testosterone, so, no cholesterol is going to
put a man in a bad place.

Eggs and heavy deadlifts and squats. Yay, feel the burn.

Speaking of which: anyone have a .fit file binding for Pharo?

See this forum thread for a clue:
https://www.thisisant.com/forum/viewthread/4275

Roassal + Dataframe on fit files would be a great thing to have.

Re: [Pharo-users] Dark Mode

[Tim Mackinnon]

I found the place to adjust this - but I need to debug it as it seems my change 
also effects the colour used to highlight selected text (which is weird).

If you modify the following method (possibly in a subclass), I found this 
helped - but haven’t figured out why text highlight colour would be impacted by 
this change?

configureWindowBorderFor: aWindow
"Made window borders a bit thcker and slightly lighter to its easier to 
distinguish 
overlapping windows"

| aStyle |

aStyle := 
SimpleBorder new 
color: self borderColor lighter lighter lighter;
width: 2.

aWindow borderStyle: aStyle.

Re: [Pharo-users] Dark Mode

[Dimitris Chloupis]

Nutrition wise, scientists always agreed that eggs contained pretty much
everything the body needs. Problem was cholesterol which the egg does
significant rise.

The fact that did change was that high cholesterol is bad, some doctors
would argue even deadly for ones health. Problem was that this fact was
based on a research that was on a very small group of subjects and if I am
not mistaken it was not even humans it was lab rats.

The problem none really funded a serious research for this fact and when
they did they discovered that indeed eggs and other food do raise
cholesterol significantly but our liver is capable of reducing the
production of cholesterol to compensate hence its nowhere near as harmful
as they used to assume.

Science is flawed mainly because finding small facts is easy and cheap but
general fact are very complex and very very expensive.

Like all things, you get what you are paying for. This is why you see and
hear so many contradictory facts. They are mostly based on simple cheap
research. Plus "fact" is purely a fantasy, our world is too complex for
facts as most people define them. There is truth sure, but not as easy to
consume and explain as we would wish.

The preference to light and dark themes is not product of bad scientific
research. I suspect the reasons are too complex for science anyway because
we are even eons away from explaining the human brain and how it works.

Pharo not only allow you to choose a theme but its theme classes are
actually very easy to use which is something it inherit from Squeak. It
took me a day to create my own theme.

The Dark UI theme class is excellent example for anyone who wants to
subclass it and create his own light or dark theme because its not that
complex.

Re: [Pharo-users] How do I get at the Morphic halos in Pharo 6.0?

[Tim Mackinnon]

On OSX, you hold the Shift and Alt keys and then click on something. I think on 
windows its probably Shift+Alt or Shift+Ctrl. 

The in-image help explains this under - Pharo Environment Help - Keyboard

[Davorin Rusevljan]

If I can throw in my 2c, themes are like nutrition facts. When I was a kid
eggs were the healthiest thing to consume in universe. Then they were a
root of all evil, and now days are nutrition packed food.

I have observed similar circles in background color usability. Pharo has
ability to choose a theme, it has both currently fashionable and older ones
to choose from. I do not see need for anything else on that front.

[Pharo-users] [Pillar] How do I include a picture which I get from aMorph imageFrom?

[H. Hirzel]

Hello

Is it possible to include a in-image picture in Pillar which I get by evaluating

myMorph imageForm?

Or do I need to write the instance of Form I get by evaluating the
expression above first as a PNG file to disk and get it from there.


PNGReadWriter
putForm: myMorph imageForm
onFileNamed: aString

If yes what is the default directory where does Pillar expects pictures --


The Pillar cheat sheet [1] and the Pillar chapter in the Pharo

Yeah, after that, not much can really stress me out that much.

And 2 x 27 inch monitors help. Pharo is great because I can make it be the

 Dimitris,

 I understand your practical reasons to have Markdown
 over Pillar and in fact I have advocated several of
 them. As I have said, Markdown ubiquity for complete
 documentation workflows (including complete books) is
 similar to git ubiquity for code. Despite having other
 personal preferences in markup and DVCS, I think is
 strategic to give them support in Pharo, without
 precluding any work on our own tools (Monticello,
 Metacello, Pillar, etc.).

 I'll try to make some experiments with integration of
 Documenter in Grafoscopio and Markdown. They'll advance
 slowly, because time constrains now that I'm trying to
 finish my thesis, but once a week I'll try to show
 advancements and make questions.

Re: [Pharo-users] How to create a minimal image ?

[Dimitris Chloupis]

for me Pharo and GUI go hand in hand, I cannot imagine Pharo without GUI. I
also despise the command line. Plus once you remove the GUI you kill the
very essence of Smalltalk.

But if that is what you(you as all people who support this) like and need,
that's your choice and I respect that.

Even back in the 80s when almost everything was command lines , I was
drooling over Amiga's 500 beautiful coloured GUIs. It started my
fascination with computer graphics and later 3d graphics and sound.

So me and the GUI are very old friends and we go hand in hand :)

Of course I understand if we want to go super minimal the GUI has to go
together with many other things that make Pharo what it is. But I dont care
for such extremes. I just wanted to reduce the fat.

Phil,

I was not aware that it is still possible to get Morphic halos in Pharo 6.0?

How do I get at them?

Hannes

Re: [Pharo-users] Where do I find a Pillar syntax summary?

[H. Hirzel]

Found the Pillar chapter of the Pharo enterprise book ("A web
perspective") by following the link on the wiki

https://github.com/pharo-project/pharo/blob/master/wiki/contents/projects.md#pharo-projects-on-smalltalkhub

then

https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/PillarChap/

Then 
https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/PillarChap/Pillar.html

So the information is somewhat hidden but available and only the link
from the Pharo books website is broken.

Re: [Pharo-users] Dark Mode

[Dimitris Chloupis]

I am no authority on dark theme because I am using my blue theme full time
and I have addressed any colour issues I had.

Retina detachment, wow that is serious ! I hope you doing better :(

Well I have myopia in both eyes, my left is 6 degrees which is pretty high.
We myopics suppose to not see very well in the dark but my visual
perception is great in dark environments even in almost complete darkness.

Its weird because as I young boy I was non stop out in the sun and I live
in Greece, here the Sun is very bright, yet it always hurt my eyes. Not
much as knife pain, but more like feeling pressure on the eye. Of course I
am not the only Greek in love with his sun glasses during summer.

My eye doctor said it was because of my eyes being light color compared to
the usual dark coloured eyes Greeks have. But I think the reason most
likely is more mysterious :D

Re: [Pharo-users] How to create a minimal image ?

[Pavel Krivanek]

What do you expect from such minimal image? Because we can produce several
intermediate steps on the way to the standard full Pharo image
(BaselineOfMorphicCore, BaselineOfMorphic, BaselineOfUI,
BaselineOfBasicTools...)

 it is created in bootstrap/scripts/build.sh under

Re: [Pharo-users] Where do I find a Pillar syntax summary?

[H. Hirzel]

P.S. Important Pillar links I have collected last week

https://github.com/pharo-project/pharo/blob/master/wiki/contents/projects.md#pharo-projects-on-smalltalkhub

Includes this one
http://pillarhub.pharocloud.com/hub/pillarhub/pillarcheatsheet
Alistair writes it is fine in Pharo 6 for what he is using it for.

In particular I am interested in adding pictures which are within the
Pharo image.

 Now I have no time for pillar per se. Now if you do it I will add it

 Tomorrow we will
use bintray for all the projects to save the pdf (booklet, books).
migrate the mooc to the makefile generator developed by luc.
make sure that it works for Pillar 50 and 60.
migrate other pillar projects to use the same.

 BTW we do not really want to have multiple version of the syntax.
 For example Pillar 50 and 60 are the same from a syntax point of view.

Re: [Pharo-users] Dark Mode

[Dimitris Chloupis]

Yeah this is a known bug at least to me when I test my blue theme. I think
however that it was fixed to an extend. Anyway closing and opening the
window will update the colors so its not a serious bug. Once the theme is
changed you should experience no issues.

Re: [Pharo-users] Where do I find a Pillar syntax summary?

[H. Hirzel]

Stephane

I went to the Pharo book web site,

Enterprise Pharo - a web perspective
Enterprise Pharo is the third volume of the series.

This link

http://files.pharo.org/books/enterprise-pharo/

and clicked on 'Pillar'

and for

https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/Pillar/Pillar.html

got HTTP ERROR 404

I think you are currently updating the book and that there are also PDFs.

How can I get at a recent version? Integration server? Where?

 Thank you for the link to the Pillar syntax summary

  http://pillarhub.pharocloud.com/hub/pillarhub/pillarcheatsheet

 and the confirmation that the constructs there work in Pharo 6 & 7 for
 basic cases. This is fine for me at the moment.


 Stephan D
 Thanks for being ready to check the full feature support in Pillar.

 A suggestion:
 A new style sheet could come as well together with a test document
 (with version indication included) for the Pillar parser.

 Then it is straightforward to determine if a particular Pillar
 installation supports a particular Pillar markup version.

 The Pillar-Tests-PetitPillar package tests individual features but not
 all in one go. If we have a test case which tests all features in one
 go it has a triple function:
 1) It is a syntax summary of all features.
 2) It serves as a living documentation.
 3) It helps to determine if a particular pillar installation in an
 image supports a particular Pillar version.

Light mode kills them.

Dark theme : can code for hours without any trouble.

At the office I am at now 90% of coders are using dark themes.

Indeed the windows buttons are annoying, I have my own little hack to make
them better.
When a control bugs you, bring a halo and try to reverse the form, usually

[Pharo-users] Pharo Group for System Browser

[Trussardi Dario Romano]

Ciao,

i work with Pharo 4.0 and with the relative  System Browser.

My goal is to define a group where i add all definition:

Package ( CMD n-e-p )
Class ( CMD n-e-c )
Protocol ( CMD n--e-t ? )
Method (  CMD n-e-m )

 relative to a specific problematic ( when i development - management 
it ).

Into Pharo 4.0 this command works with some problem ( they do not 
always work as you expect )

I do some test with the Pharo 6.1 and seems that the group handle only 
the Package reference add.

Anyone can give me directions about it?

How i can 'group' some reference ( Package - Class - Method ) into the 
System Browser to have control 

to all the method relative a specific problematic ?

 I forget something?

Thanks,

Dario

Would a class-level save work? One could trigger the collapse there as well.

A concrete problem with the Newspeak editor/browser is the invisibility 
of multiple open edits when editing a large class. There might be 
changes scrolled away. What it misses is an efficient way of looking 
only at the open edits. That could be achieved by having a view

What do you mean by the interaction model? Because, even at low-level, Bloc
has already chosen a interaction model (probably a thread per window
dispatching events to components arranged in a tree model by bounding boxes
+ a focus for input, and propagation of damage events upstream).

Do you means something like MVC or PAC-Amodeus?

The InterViews code (and UniDraw) is easy to find; it has been maintained
for open source system under the name ivTools. In it, iDraw is a fine
example of UniDraw, and it's GUI (the way it shows scrolling without
scrollbars is typical of the visualisation community). Another example is
TkInetd.

Something that is not usually built in ivTools, but which I think is an
absolute must study item for anybody doing GUI toolkits, is Doc. The source
is available, probably in the InterViews 3.0 source distribution. Doc is
also described in the book Design Pattern.

I agree about that: works in Pharo. I expect it to be good, on the level of
those toolkits from the 90's, which means probably as good as anything
commercially available today, and perfectly suited to Pharo needs.

Well, the question arise because I think one of the thing you seems to be
targeting for documentation is iPython, and iPython is sequential (the flow
of statements through the document) and well suited to its purpose. And the
GTExamples pragmas looks like a poor man's graph of dependents examples.

At the same time, I see the GT concrete realisation as working often with a
single object; that is a single GT inspector showing two panes on a screen
(or a playground, which means a single object and a script).

So I wonder if that restriction is significant.


> But, I am not sure I actually addressed your question.

I'm not sure I know what I am looking for exactly myself. So that make that
question difficult to answer?

I'm starting to piece around what I would need for this, one item at a
time. It's not important however; it does not has enough research value,
just that it could be interesting.

Thierry

it is created in bootstrap/scripts/build.sh under name Pharo7.0-metacello-*

Bloc is a low level GUI framework. The widgets and the interaction model for 
building complete applications belongs to a layer above it. This is what Brick 
is supposed to be. We are right now at the level of building widgets and did 
not yet decide on the concrete the interaction model. That is why to make it 
useful, we use the editor embedded inside a Morphic-based interface.

I did not know Amulet, but Interviews and Unidraw I read about more than a 
decade ago and even then I did not manage to get my hands on a working copy. 
Unidraw is a high level component-based engine for building applications that 
bares more similarities with something like Glamour. Nevertheless, I never saw 
Unidraw in practice and from the documentation that is available it is hard to 
distinguish the details, and details matter a lot.

So, perhaps the most important difference is that Bloc works now in Pharo. This 
does not mean that it is the best possible framework, only that it is the best 
we could do. We are confident it is quite good, but it remains to be seen 
whether it will be enough to be practical.


> - Will some of your workflows enables exploration of parallel,

This is certainly an area of interest, although not an easy one. We already 
used logging that collected signals from multiple processes and explored them 
inside GT Inspector, but certainly more is needed.


> - Will we be able to have non-linear execution paths and explorations through 
> examples and documentation?

I am not sure what you mean by execution paths, but when it comes to 
exploration, this is exactly one of the things we are after: there are multiple 
contexts one might want to “consume" code in and most of these are unforeseen. 
For example, showing a method inside a piece of documentation provides an entry 
point that invites a kind of navigation that is orthogonal to the default code 
structure. The whole idea behind humane assessment is that we should craft 
tools to match the current context of interest and this implies new angles of 
exploration, and this is what GT offers. Last year at ESUG I provided some 
examples of such exploration paths:
https://youtu.be/XWOOJa3kEa0?list=PLqvTNJtc942Cs9Qo4ikCGrUNtAw93Q0JA

But, I am not sure I actually addressed your question.
