Re: [Pharo-users] Rule engine

by stepharo

I know that Herve Verjus and Marc-Philippe Huget wrote and publish a forward and backward chainer. Now I would be interested in a system that can also use objects for facts. So Udo told me that he is doing a rete. Now if I remember correctly kris gybels had a rete .

Re: [Pharo-users] Problem due to deprecation of class Url in Pharo 3 and Moose 5.0

by PBKResearch

Hello All Just a follow-up to this query posted three weeks ago. I was e-mailed a week ago by Monty telling me about an alternative approach to my problem: "Hi Peter. I'm writing you because of your post on the Pharo users list two weeks ago on problems with Todd Blanchard's HTML/CSS parser and ZnUrl. I'm a maintainer of PharoExtras/XMLParser on SmalltalkHub, and you may not know, but there's an optional HTML parsing add-on in the repo, ConfigurationOfXMLParserHTML. This loads two other parsers, SAXHTMLHandler (SAX) and XMLHTMLParser (DOM, probably the one you want), that convert malformed HTML to well-formed XML. [remainder clipped]" I was a bit unsure about this, partly because I am not very familiar with XML, partly because it seemed perverse to change the representation just to analyse the DOM. However, now I have looked into it more it seems very sensible; the manipulation of the XML version of the DOM is much easier. So I have decided to discontinue using the Blanchard parser and switch to XMLHTMLParser, which has the additional advantage of being actively maintained. The moral is that it is always worth posting questions here. There are many people watching, and there is the chance of a bit of lateral thinking. Posted here also because my attempts to e-mail Monty directly have failed, so thanks again Monty. Peter Kenny From: PBKResearch [mailto:peter@pbkresearch.co.uk] Sent: 10 January 2015 10:41 To: 'pharo-users(a)lists.pharo.org' Subject: Problem due to deprecation of class Url in Pharo 3 and Moose 5.0 Hello I have run into a problem in moving some existing work from earlier versions of Pharo/Moose. I have found a work around, but I wonder if there is a tidier way of handling it. I make frequent use of Todd Blanchard's HTML parser and validator, HTMCSS (http://smalltalkhub.com/#!/~ToddBlanchard/HTMCSSValidatingParser) which was originally written for Squeak but has performed without trouble on earlier versions of Pharo. When I try to use it on Moose 5.0, I get frequent warning messages about Url being deprecated. I have made the problem go away by commenting out the deprecation warning in Url class>>new, but I wonder what should be done on a more permanent basis. [clipped] Thanks in advance for any help or suggestions. Peter Kenny

Sorry to be blunt but: (1) you have to learn a bit about Metacello configurations (as a user) (2) you should have read the class comment Extending the configuration browser is a good idea, but it is work (and I am not sure configurations can be introspected enough, have enough meta data. that is probably why it is not there). > On 31 Jan 2015, at 01:59, Martin BÃ¤hr <mbaehr(a)email.archlab.tuwien.ac.at> wrote: > > (new thread because this is not a reply to sven, but a general observation for pharo devs) > > Excerpts from Sven Van Caekenberghe's message of 2015-01-30 21:19:01 +0100: >> Are you sure you understand how Metacello configurations and groups works ? >> You are misinterpreting what you see. > > how am i supposed to interpret the fact that nothing happens? > >> Please read the class comment of ConfigurationOfZincHTTPComponents. >> You have to load (at least) the 'REST' group for what you want. > > and i am supposed to discover this how? > > two feature requests to help new pharo users: > show comments by default. > add support for groups in the configuration browser so they can be selected and > loaded right there. > > greetings, martin. > > -- > eKita - the online platform for your entire academic life > -- > chief engineer eKita.co > pike programmer pike.lysator.liu.se caudium.net societyserver.org > secretary beijinglug.org > mentor fossasia.org > foresight developer foresightlinux.org realss.com > unix sysadmin > Martin BÃ¤hr working in china http://societyserver.org/mbaehr/ >
