Re: [Pharo-users] Anyone knows how to get the list of available archetype with Pillar?

by Tim Mackinnon

Iâm also interested in Pillar and Ecstatic - how do you even get started with this? I would like to replace my experiment with Metalsmith.io <http://metalsmith.io/> with ecstatic/pillar but its quite opaque at the moment. It feels like its very similar, and my reasons for switching are that the smalltalk I love is malleable and easy to get going - but its finding the threads to get started that are missing (a bit ironic for a static document generator). If anyone can share some clues, I have some energy for helping.

How to use uFFI with String

by horrido

There is shockingly very little documentation on how to use uFFI. In particular, I have the following situation... A shared C lib has the following function: void get_machine(char *machine) { uname(&uname_s); strcpy(machine, uname_s.machine); } It copies the content of a string value into the buffer passed to it (char *machine). I want to call this function from Pharo, thus: buffer := String new: 64. self ffiCall: #( void get_machine(String buffer) ). The buffer never receives the string value (it just contains the 64 initiialized spaces). Clearly, I'm misunderstanding the proper mechanism for doing this. [There are other functions in the shared C lib that work fine, such as: uint get_uptime() { sysinfo(&info); return info.uptime; } Returning integers or floats is no problem. But passing arguments by reference seems to be verboten.] -- View this message in context: http://forum.world.st/How-to-use-uFFI-with-String-tp4947890.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Problems loading XML System ( was [Zinc] ZnInvalidUTF8: Illegal leading byte for utf-8 encoding)

by monty

Creating two separate DOM subtrees for two descendants of the body element should be faster and consume less memory than creating one subtree for the entire body. You should also consider benchmarking different approaches, and using profiling to identify which of the parsing, querying, network IO, or whatever is your bottleneck before optimizing. > Sent: Saturday, May 20, 2017 at 7:08 AM > From: PBKResearch <peter(a)pbkresearch.co.uk> > To: "'Any question about pharo is welcome'" <pharo-users(a)lists.pharo.org> > Subject: Re: [Pharo-users] Problems loading XML System ( was [Zinc] ZnInvalidUTF8: Illegal leading byte for utf-8 encoding) > > Monty > > Many thanks for your patient explanation. I would like to try one supplementary question, if I may. Almost all my work involves reading HTML files from the web and extracting relevant sections, and I am trying to work out how to divide the effort between StAX and XPath. For example, if I am reading an article from Frankfurter Allgemeine, I am looking for two tags: > <div id="artikelEinleitung" class="FAZArtikelEinleitung"> > <div class="FAZArtikelText" itemprop="articleBody"> > which contain the intro and body of the article; everything else can be discarded. > > Using StAX, I can find the first <div> with something like this (adapted from your second snippet): > > [((tag := parser peek) isStartTagNamed: 'div') and: [ tag hasAttributes and: [(tag attributeAt: 'class') = 'FAZArtikelEinleitung']]] > whileFalse: [parser next]. > intro := parser nextNode. > > and similarly for the body.

If there's no next "head" element, it exhausts the event stream looking for one.

The version of XML-Parser in that was dated 18 July 2016 (configuration monty.233), so I installed versions of XML-Parser-HTML and XML-Parser-StAX contemporary with that. (The respective configurations are monty.48 and monty.39). With these versions all my previous XMLHTMLParser operations work as before, and I have been able to use the StAX parser in a simple way.

I updated to ConfigurationOfXMLParser(monty.302), which is the latest version on the smalltalkhub repository, and then used the load version in the class comment, which loads the stable default. Similarly, I loaded ConfigurationOfXMLParserHTML(monty.62) and ConfigurationOfXMLParserStAX(monty.51), again using stable and default.

My original purpose was just to answer Paul deBruicker's query, namely to parse an html file and stop reading at the end of the <head> section.
