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

THANKS for the feedback. Normally we talked about it with andrei and doru at ESUG. Can you check if this was fixed in Pharo 60 because someone told me that it was but I'm not sure.

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

by 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 . cheers -ben On Thu, Sep 1, 2016 at 12:59 AM, Ben Coman <btc(a)openinworld.com> wrote: > For this definition pulled from a library header file... > typedef struct { > const void *data; > unsigned private_flags; > } CXString; > > which is used with a helper function to get a usable string like... > void show_clang_version(void) > { CXString version = clang_getClangVersion(); > printf("%s\n", clang_getCString(version)); > clang_disposeString(version); > } > > ==> 'Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on > LLVM 3.5.0)' > > > So I defined... > FFIExternalStructure subclass: #CXString > instanceVariableNames: '' > classVariableNames: '' > package: 'LibCLang' > > and ignoring the const as advised in the manual [1], I try... > CXString class >> fieldsDesc > ^ #( > void *data; > unsigned private_flags; > ) > > but... > CXString rebuildFieldAccessors. > ==>Error: Unable to resolve external type: unsigned > > I also tried "unsigned int private_flags;" > but get the same error.

Spec Text Emphasis

by 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! ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spec-Text-Emphasis-tp4913688.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

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.

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

by 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? --Hannes On 9/1/16, H.

Re: [Pharo-users] Coding XPath as Smalltalk

by PBKResearch

Hi Hernan I donât understand your first question â I canât 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. Peter From: Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] On Behalf Of HernÃ¡n Morales Durand Sent: 01 September 2016 18:54 To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Subject: Re: [Pharo-users] Coding XPath as Smalltalk Hi Peter, 2016-09-01 10:26 GMT-03:00 PBKResearch <peter(a)pbkresearch.co.uk <mailto:peter@pbkresearch.co.uk> >: 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. Peter Kenny
