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

by Ben Coman

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. cheers -ben On Fri, Sep 2, 2016 at 3:37 AM, H.

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 However, I am probably using a somewhat out of date version; I downloaded it about a year ago.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

No right-button menu in Inspector on a ByteString

by 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
