Hello Hans,
the standard way to build GUIs using Pharo is to use Spec. I suggest you have a
look at the documentation of Spec online, do the tutorial and then you can
start experimenting. The easiest way to see the Spec documentation is here:

Hello , here is Hans , The Byte Surfer ,
the smalltalk code is from books of year 1992 and 1993 1988 and 1987.
I have a lot of books around the world . ALL of the Topic SMALLTALK
80. Only 80 !!!
Because i am a absolute beginner and want to learn smalltalk 80.
I realized that thing have changed. for example GUI programming
Mosttimes there is a optional library needed for creation. There is a
optional IDE i know , for those things.
No Matter !
I dont know anything about the NEW TOOLS and Replacements in
actual Smalltalk Engineering like PHARO.
Please tell me what i have to learn.
What is GUI IDE in Pharo. Do i have to learn Morpic. What else
for Window and Buttons design ?
The Pharo ( and actual squeak ) have very much weight for a beginner.
Is it right , that all " NEW STUFF " is decribed in the two manuals :
Pharo by Example + Deep into Pharo.
Or is there any other actual description about "Up to date programming
Pharo" ????
Sincerely Your Friend
Hans
The Byte Surfer
PS. Wish to have Smalltalk 80 from XEROX 1987 here. ha ha ha

Hello,
I don't really know how to answer.
Are your examples really from smalltalk-80 ? Were they running on the
Xerox-D microcoded machine ? Because I don't think there are anymore
smalltalk-80 available right now, nor machine that can run it. There's a
smalltalk-78 running on javascript on the web but that's a bit different.
Here you're on the Pharo mailing list, which is a smalltalk which has
evolved during 35 years starting from smalltalk-80, so it's quite different
from smalltalk-80 right now (for example, closures and exceptions were
added, support for modern computers too).
To use window as you are doing something like that works:
| window |
window := StandardWindow new.
window title: 'Hello World' .
window open
However nowadays people use frameworks to build UIs in Pharo, not such
APIs. So it depends what you want to do.

Hi Offray,
I think I better understand what you are doing now, and how you are using STON.
What I think might help you (in your use case), is to add two options:
1 - to STONWriter #keepNewlines that converts any newline inside Strings to a
newline as specified by #newline: instead of encoding it as unprintable
2 - to STONReader #convertNewlines that converts any newline inside Strings to
a newline as specified by #newline: instead of keeping it as is
Now, 2 is already there, except that any newline read is kept as it is, while I
think it would be better to convert CR, LF and CRLF to just one (to be
specified).
Similarly, 1 would convert CR, LF and CRLF to a single one (to be specified).
Without these conversions, mixups between different line end conventions could
easily happen. I think it is too much work to do this in your own models.
If you think this would help, I'll put this on my todo.

Hi Sven,
Sorry for my late response. The constructive comments on the list and yours in
particular are very valuable to my. I was finishing some details, so only until
now I have the time to implement your suggestions. The new code for custom keys
on bibtex files from pharo is published at [1] (by the grace of Doru's easy
publishing of playgrounds on your stfx server)
[1] http://ws.stfx.eu/3CEKQQQ3NL2E
By the way the article I'm writing is about a tool for open, citizen, garage
research and science developed in Pharo. It is published at [2] and was stored
nicely using STON[3] and is superb. To test the tool, the article was wrote on
it.

[4]
http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/tip/Docs/Es/Articulos/Libertadores/bootstrapping-objeto-investigacion.markdown
The only thing I would add to STON would be an option to support line breaks so
long character sequences can be broken to make the format DVCS friendly (git,
fossil, etc) and support collaboration and changes tracking. At this moment,
because of the long lines in STON, the files are treated as binaries by fossil
:-/.
Thanks for STON and your lessons,
Offray

Hi,
Thanks again. I have a small script, using Citezen which does the trick. I can
explore and modify the BibTeX File from the playground with this:

bibStream nextPutAll:
(bibOutputer entryToBibtexString:
(bibliography entries at: index)); cr.].
bibliography.
bibFile writeStreamDo: [:stream |
stream nextPutAll: bibStream contents withUnixLineEndings ].
bibStream contents.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Some constructive comments about your code (smaller is always better,
especially for interactive snippets):
- you can change the #detect: to [ :each | each extension = #bib ]
- you can iterate directly over the entries with #do: as in bibliography
entries do: [ :each | .. ] which saves you the #at: index
- there are handy unary shortcuts for accessing elements, like #first, #second
and so on (up to #ninth) which also save you parenthesis
- you can also construct strings using the idiom String streamContents: [
:bibStream | .. ]
Sorry, these jumped to me when I saw your code, I hope you don't mind ;-)
I will put some functionality inspired by this on my prototype this weekend.
Cheers,

from Damien Pollet:
You will need to load the .bib file from zotero (read the file however
you like, then pass the stream to the CZ parser). You'll get a
CZBibSet (I don't recall the name exactly) which represents the
contents of the file. A Set is composed of entries, each of which has
a key and a set of fields. Finally, fields accept a few different
kinds of values.
Your processing is just iterating a set then setting the key of each
entry (or possibly removing and re-adding the entry, I don't recall if
it's implemented like a dictionary or more like a list).

Now I want to make a post-processing of the bibtex file exported

I have already installed Citizen and open it on the browser to
see the code,
but I can find any place to start with examples.
Any advice on how to solve this issue will be appreciated.

Hello Hans
My opinion is that you waste your time trying to find a smalltalk 80 just
because you were used to it. Its like me returning back to GWBASIC which is
the first programming language I learned to use back in 1988. Why use
something so old that cant take advantage of new technology and new
software ? It will only make suffer and limit you in many diffirent ways.
Pharo is a modern implementation of smalltalk it does not try to stick to
the past it prefers to embrace the future of smalltalk.
Morphic is what Pharo has inherited from Squeak and is by far the most
dominant and most mature GUI API of Pharo. New kids in the block graphic
wise is Spec , Athens and Roassal.The only common amongst those three is
that they are no GUI APIs but they are graphic libraries
Spec is wrapper above GUI APIs currently it wraps only Morphic and makes it
easier to create complex GUIs. Unlike Morphic however has a steep learning
curve but pharoers prefer it because it is easier to manage. Spec
documentation is in a dedicate site (Just google "spec pharo" and you will
find it) and in Pharo For The Enterprise book.
Athens is also similarly to spec a wrapper above vector graphics libraries
, currently it wraps the cairo libraries and can mix with Morphic . Athens
docs are in Pharo For The Enterprise book plus there is a athens
interactive tutorial in smalltalkhub
Roassal is part of the moose tools a collection of tools for the
visualisation and organisation of code. Roassal is also a wrapper above
graphic libraries , it wraps both Morphic and Athens and it has also some
GUI classes . Roassal documentation is in Deep Into Pharo and I think it
has a chapter in Pharo for the Enterprise. Agains all these doc are easily
revealed with a simple google search.
GUI wise I will say that Morphic is still the undisputed king and Spec
becomes slowly very popular as a way to manage Morphic easily.
There is also a new and only Morphic replacement in the works that is
called Bloc but I have not tested to provide information about it.
So both Morphic and Spec are viable options. Obviously Morphic is more
documented because of Squeak but Spec is more actively developed right now
in Pharo.
Whatever you pick any problems you have you ask here and you get your
questions answered and you can also ask at stackoverflow if you have
already an account there.
There are also other GUI and Graphic libraries inside Pharo and outside
Pharo , Pharo like squeak comes with several FFIs that allows you to use
external C / C++ library (C++ libraries will have to be wrapped as C
libraries) which this alone give you access to pretty much every GUI
libraries that popular languages use. JNIPORT is Smalltalk library that
allow Pharo to use Java libraries so you can also use Swing. I am also
working on a way to allow Pharo to use Python libraries , I was partly
successful into creating QT GUIs via pyQT which is the python wrappers for
QT GUI API . QT is probably the most powerful GUI library out and so much
more than that.
So in reality you have like a ton of options , everything comes with its
advantages and disadvantages but for now Morphic and Spec should be enough
for your needs.
