[Pharo-users] Spec / GT Inspector integration

[Alistair Grant]

If I have a CompositeModel which I want to display as a tab in a GT
Inspector, what should the inspector method look like?  (I haven't been
able to find any examples in the image or on the web)

I assume it should be something like:


gtInspectEditIn: composite


^ composite spec
title: 'Edit';
display: [ :anObject | MyCompositeModelEditor on: anObject ].


But it isn't clear to me what the display block should be returning.

I can successfully open the window using:


MyCompositeModelEditor new
editObject: anObject;
openWithSpec.


Thanks,
Alistair

Here is an example how you can create a spec based presentation (an
IconListModel) ).
Add this method to the other gtInspectorMethods for class Morph (instance
side):

gtInspectorSubmorphs2In: composite

composite spec
title: 'Submorphs2';
display: [:each ||lm|
lm:= IconListModel new.
lm items: each submorphs.
lm icons:[:item | item taskThumbnailOfSize: (16@16) ].
lm displayBlock:[:item | item printString -> item class name].
lm buildWithSpec.
lm
]

Re: [Pharo-users] BitArray and BooleanArray ?

[Ben Coman]

I don't know the answer but I assume you a looking for a memory
efficient way of storing booleans.  So perhaps the Bit Field layouts
discussed here [1] may be of interest considering the recent
introduction of Slots to Pharo.  Otherwise I verry vaguely remember
Bitmap used for this somewhere. Sorry I can't be more precise.

[Pharo-users] Coding XPath as Smalltalk

[PBKResearch]

Hello

 

I am using XPath as a way of dissecting web pages, especially from
Wiktionary. Generally I get good results, but I could get useful extra
flexibility by using the binary Smalltalk operators to represent XPath, as
mentioned at the end of the class comment for XPath. However, the
description there is very terse, and I am having difficulty seeing how to
include more complex expressions, especially attribute tests. I have put
some of my XPath expressions through the XPath compiler and looked at the
output, and out of that I have found expressions which work but look very
clumsy. As an example, I have used the fragment:

 

document xPath: '//div[@id=''catlinks'']//li//text()'

 

and found that an equivalent is:

 

document //'div' ?? [:node :x :y|(node attributeAt: 'id') =
'catlinks']//'li'//[:n| n isStringNode]].

(I had to put two dummy arguments in the three-argument block to get it to
work.) 

 

Is there a more extensive explanation of the use of these binary operators?
If not, could some kind person show me the most concise translation of the
sample XPath above, to give me a start in working out more complex cases?

 

Many thanks for any help.

 

Peter Kenny

Form uses Bitmap to represent graphical stuff. Bitmap itself is a subclass of 
ArrayedCollection.

[Pharo-users] [ANN] RProjectConnector V2.1

[Blondeau Vincent]

Hello everyone,

I am glad to announce the release of version 2.1 of the RProjectConnector.
The binding between Pharo and R (https://www.r-project.org/) is now translated 
to UFFI and so to Pharo 6.0.

You can call directly your R methods from Pharo. For example, with the famous 
iris clustering example:

  iris := 'eval' asREval: {RObject findVar: 'iris'}.
  'plot'
asREval:
{(iris at: 'Petal.Length').
(iris at: 'Petal.Width').
(#pch -> 21).
(#xlab -> 'length').
(#ylab -> 'Width').
(#bg  ->((iris at: 'Species') collect: [ :value 
| {'red'. 'green3'. 'blue'} at: value ])).
(#main -> 'Edgar Anderson''s Iris Data')}.
  iris inspect.

To use it, you should install R and copy the R libraries near the Pharo VM (see 
the documentation on SmalltalkHub 
(http://smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector) for how to 
proceed).


Don't forget to relaunch Pharo after the installation to be able to use the 
connector.

Only basic features are implemented yet, but you can participate to its 
extension!

Cheers,
Vincent Blondeau

Re: [Pharo-users] UFFI const, unsigned, opaque-ish types

[Ben Coman]

Thanks Esteban. That worked.

However it may be good to be more permissive about allowing const to
reduce the surprises for FFI users.  Same for unsigned.

Reviewing   FFIExternalStructureFIeldParser>>praseFields:structure:
I see declarations are parsed simply left-to-right, which okay as the
simplest-thing-that-would-work.   However (in case I get inspired...),
would this benefit from more complex parsing like described at [1] and
[2]?  Or is this unlikely to be a concern in prcatice, and/or the rest
of FFI not ready receive such complex declarations from the parser?

Re: [Pharo-users] [Pharo-dev] [ANN] RProjectConnector V2.1

[Blondeau Vincent]

Sorry, I haven’t a Mac.

First, you have to install R.
Then, I think you should only have to copy the R libraries (somewhere in the 
disk^^) to the Pharo VM folder.

Tell me if it works ;)

Re: [Pharo-users] Coding XPath as Smalltalk

[PBKResearch]

Hi Cédrik

 

I started out using Soup, but I found out that it does what its name suggests, 
and jumbles up the contents of the pages. I now parse the pages with 
XMLHTMLParser, which preserves the original structure exactly. The point of 
XPath is that it is a convenient way of specifying a route through the 
structure to the desired information. So the XPath I cited says ‘find a DIV 
node, at any depth, which has id=”catlinks”, then find a descendant which is a 
LI node, then find the text of any descendants.’

[Pharo-users] No right-button menu in Inspector on a ByteString

[H. Hirzel]

Hello

I have an Inspector on n a ByteString open and would like to copy out
the string into the clipboard.

I can select the text but there is no right-mouse button menu to copy it.

ALT-C just replaces the text with a c
CTRL-C the same.

I am using Pharo 5.0 on Linux Mint.

In the preferences I found nothing how to activate a right mouse
button menu nor something about activating an edit menu.

What am I missing?

Kind regards

Hannes

Re: [Pharo-users] No right-button menu in Inspector on a ByteString

[H. Hirzel]

Found the answer:

the right-mouse button menu is only available in the 'raw' tab ...

Re: [Pharo-users] Coding XPath as Smalltalk

[PBKResearch]

Hi Hernan

 

I don’t understand your first question – I can’t see a connection between 
SPARQL and what I am doing.

 

I downloaded XPath from http://smalltalkhub.com/mc/PharoExtras/XPath/. However, 
I am probably using a somewhat out of date version; I downloaded it about a 
year ago.

Hello

 

I am using XPath as a way of dissecting web pages, especially from Wiktionary. 

 

Any specific reason to not use the SPARQL endpoint?


 

Generally I get good results, but I could get useful extra flexibility by using 
the binary Smalltalk operators to represent XPath, as mentioned at the end of 
the class comment for XPath. However, the description there is very terse, and 
I am having difficulty seeing how to include more complex expressions, 
especially attribute tests. 

 

Which XPath version are you using? How did you installed it?


 

I have put some of my XPath expressions through the XPath compiler and looked 
at the output, and out of that I have found expressions which work but look 
very clumsy. As an example, I have used the fragment:

 

document xPath: '//div[@id=''catlinks'']//li//text()'

 

and found that an equivalent is:

 

document //'div' ?? [:node :x :y|(node attributeAt: 'id') = 
'catlinks']//'li'//[:n| n isStringNode]].

(I had to put two dummy arguments in the three-argument block to get it to 
work.) 

 

Is there a more extensive explanation of the use of these binary operators? If 
not, could some kind person show me the most concise translation of the sample 
XPath above, to give me a start in working out more complex cases?

 

Many thanks for any help.

You could get the Wikitionary data by querying a SPARQL endpoint
http://wiktionary.dbpedia.org/sparql instead of scrapping web pages (which
seems more difficult)

I don't know about that version. I copied an old version from SqueakSource
(with permission) and updated from time to time, but there is no much.
There is also a XPath2 repository which you may try.

Re: [Pharo-users] How do I display a text in a text window?

[H. Hirzel]

Answer:

To open a text window with text I do

 Workspace openContents: (MyTextCollection at: 101).


Display as text only:

At the bottom I can switch between

- plain text
- smalltalk scripting

But the text remains red in both cases.

What am I missing?

I agree.  I've suffered the same need previously.  Unless there is a
particular reason its been designed against, I'd request the usual
shortcut keys work.  I often want to use ctrl-b, ctrl-m in the default
tab, even though switching to the raw tab works.

[Pharo-users] Spec Text Emphasis

[Sean P. DeNigris]

Is there a way to change the emphasis of Spec text (TextModel/TextInputModel,
or even LabelModel - I would trade edit-ability for styling)?

The following successfully added the attribute to the text, but it didn't
display in Spec:
checkbox whenActivatedDo: [ self textModel text: (self textModel text
addAttribute: TextEmphasis struckOut) ].

Thanks!

[Pharo-users] UFFI cleanup of externally allocated memory (was Re: UFFI const, unsigned, opaque-ish types)

[Ben Coman]

Referring to the example show_clang_version() below, cleanup is done
with clang_disposeString(). How does UFFI hook into the object
finalisation mechanism to call this when the object is garage
collected.  My searches result mostly in info on weak collections and
its not clear how this translates to FFI.  Some detail on this would
be useful for the FFI manual .

Normally we talked about it with andrei and doru at ESUG.

it was but I'm not sure.

[Pharo-users] Slides online: "Perfection & Feedback Loops" talk from esug

[Marcus Denker]

Hi,

At ESUG last Friday I gave a talk "Perfection & Feedback Loops or: why worse is 
better”, I was asked for the slides.

They are now online:


http://www.slideshare.net/MarcusDenker/perfection-feedback-loops-or-why-worse-is-better-65540840

As the slides do not contain much (just headlines), I created a special 
“Annotated” version with links and some comments
so one can follow better:

http://marcusdenker.de/talks/16ESUG/FeedbackLoopsAnnotated.pdf

PDF and .key file are there, too: http://marcusdenker.de/talks/16ESUG/
(the .key file contains the embedded videos shown).

A video of the presentation should be available soon.

LabelModel has #emphasis:

LabelModel new
emphasis: #(bold);
label: 'bold';
openWithSpec

TextModel accepts Text:

TextModel new
text: 'bold' asText allBold, (' red' asText makeAllColor: Color red);
openWithSpec

TextInputFieldModel will most likely require #whenBuiltDo: and Morphic hacking.
