Thankfully, Attila gave us the final explanation for the regex mystery ;-) So I guess it is best to stick with "normal" strings for the most part for several reasons: * performance: (matching strings is probably a lot faster than matching a regex) * security / stability: looking back at my own experiments with regular expressions, you "never know" what exact urls are really being served. You need to do extensive testing on which URLs match and which don't. Sure this is not true if you know regex very well ;-) Joachim -- ----------------------------------------------------------------------- Objektfabrik Joachim Tuchel mailto:jtuchel@objektfabrik.de Fliederweg 1 http://www.objektfabrik.de D-71640 Ludwigsburg http://joachimtuchel.wordpress.com Telefon: +49 7141 56 10 86 0 Fax: +49 7141 56 10 86 1

Re: [Pharo-users] Teapot and Regex
by Attila Magyar Aug. 4, 2015

Hi Marcus, It seems you're trying to define a matcher on the query parameters. It's not going to work. An url consist of path a the query part. These are separeted by a question mark. http://localhost:1701/foo/bar?q1=xx&q2=yy In this example /foo/bar is the path, and q1 and q2 are the query params. When you define a route in Teapot you specify the path part (either with wildcards or with regexp). Teapot will select the matching route when a request comes in based on the path part, and it will parse the query part (in fact Zn does this), and make the query parameters accessible in the request object. For example GET: '/foo/bar' -> [:req | req at: #q1] This matches to an url whose path part is /foo/bar, even if there is no query part, or if it has many query parameters. In your example, you've defined the query part in the matcher, but since it is not part of the incoming url, you've got 404. But if you share what you're trying to accomplish I may be able to help.

Create maps from an SVG file in Roassal
by FranÃ§ois Stephany Aug. 4, 2015

Aug. 4, 2015

Hi there, I'm trying to import an SVG file describing the provinces of Belgium in Roassal. I've cleaned an SVG file found on wikipedia and trying to import it. I'm trying to imitate the way it is done with Countries. So: RTMapBuilder class>>provincesOfBelgium > ^ #(#antwerp #brussels #eastFlanders #flemishBrabant #hainaut #liege > #limburg #luxembourg #namur #walloonBrabant #westFlanders) > and implemented to corresponding SVG paths. Here's one example: RTSVGPath class>> antwerp > ^'m 177.419,25.0693 1.379,-3.5593 -2.986,-1.3778 -3.33,0.5742 > -0.114,-3.1001 -4.019,-4.0187 1.492,-5.9704 -2.181,-2.8706 -1.952,-0.2298 > -1.034,-1.2628 -2.411,5.1667 -3.673,3.7892 -3.101,-2.067 -5.396,1.378 > -2.068,-1.8371 4.479,-0.9188 0.345,-5.1667 -6.2,-2.1815 -4.938,5.741 > 0.114,2.8704 -8.611,-0.574 1.264,-5.5112 -5.397,0 -6.43,3.4444 1.263,4.5929 > 2.411,2.7555 -1.492,2.6409 -4.478,-0.6891 0.115,-2.7555 -6.43,0.3443 > 0,2.4112 2.296,0.5743 -0.345,5.5112 3.904,1.0336 -3.1,3.3295 3.056,7.4863 > 0.504,5.9475 -7.923,0.2296 -2.985,3.1002 1.722,1.837 -0.114,3.5595 > 2.889,0.4893 3.352,-0.9423 7.038,4.5375 3.704,-0.5553 1.759,1.7593 > 3.149,-1.7593 4.075,2.1297 2.963,-3.6118 11.112,-1.7592 0.092,3.3337 > 11.576,-3.6113 1.204,-3.0562 5.001,-0.8332 2.129,-3.8894 4.723,-0.7409 > 0.741,-1.9448 2.223,0.8336 1.481,-0.8336 0.186,-4.9079 -4.075,-2.0373 > 1.605,-5.4063 z'. Very naively, I've tried: provinceExample > "self new provinceExample" > | b | > b := RTMapBuilder new. > b countries: RTMapBuilder provincesOfBelgium. > b color: Color lightGrey. > b open. Which does not display anything. I suspect the problem lies in the coordinates of my paths. Is there a README somehwere or the original file that was used to generate the world map of the examples?

Hi, shouldn't there be Announcements chapter in the new PharoByExampleUpdated book? Because I don't see it there and I think it should be there, since currently I don't see any authoritative source of information for people about Announcements. Thanks, Peter

Fuel Error

While materializing, I'm getting a Fuel error that's ground one of my projects to a halt. Luckily, there's not *too* much data involved, but I'd like to get it back. <http://forum.world.st/file/n4840866/Screenshot_2015-08-03_19.png> Ever see anything like this?

handling exceptions in jniport
by Tudor Girba Aug. 4, 2015

Aug. 4, 2015

Hi Joachim, As I mentioned in a previous post, all Pharo Exceptions are swallowed during a dispatch from Java. This means that during a callback from Java to Pharo, you also cannot debug. >From the looks of things, I see the issue is here: JavaCallbackRegistry>>safeDispatch: aRequest to: a2Block "private -- invoke the handler for aRequest in an environment that will ensure that some sort of response is always sent back to the requester. This is *vital* since otherwise we will almost certainly deadlock ourselves" [ [[self dispatch: aRequest to: a2Block] on: JavaException do: [:err | aRequest notifyError: err]] on: JNIPortUtility exceptionsWithoutNotifications do: [:err | aRequest notifyIgnored: 'The Smalltalk handler threw a non-Java exception (', err printString , ')'] ] ifCurtailed: [aRequest notifyIgnored: 'The Smalltalk handler did not complete normally']. Is there no way to allow for some debugging? At the very least, I would like to suggest to log the exceptions with continuations using Beacon to allow for postmortem debugging. What do you think?

Sharing Inter-image Data
by Sean P. DeNigris Aug. 4, 2015

Aug. 4, 2015

When using any tool that exposes objects outside the image - Seaside, Amber, rST - how does one guard against simultaneous edits? Up until now, I've been perfectly content with single images and read-only web apps, but now that I'm considering some stateful web apps/services, I can't remember ever seeing locking addressed. And I wonder if all the cool new JS technology could make the process more responsive i.e. notify the client if the underlying data has changed... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Sharing-Inter-image-Data-tp4840912.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Am 04.08.15 um 13:34 schrieb Marcus Kemper via Pharo-users: Hi Marcus, I am slowly getting what Teapot does... So you setup an Association with a String that matches the URL of an incoming request as key and its handler block as value. So you should be able to use "req at: #r" also when using the Regex as matching criteria. Once you confirm this, the ordering is neither relevant nor a problem for you and you can go forward. Just forget about indexed access to request data for the future. Please let us know if access by symbols works for you.
