Can I control the location of the PharoDebug.log

by Dale Henrichs

It appears that the PharoDebug.log can be dropped into the directory from which a Pharo image is launched ... I would have expected it to be dropped into the local directory, but that does not appear to be the case ... I've looked in the Settings Browser and there does not appear to be a way to influence the location of the PharoDebug.log. I am currently using the `st` command line handler if that is important. I've googled for PharoDebug.log to no avail. Any help will be appreciated, Dale

more fun with System>>Local directory settings

by Dale Henrichs

... the last time we talked[1], I was wondering why my System >> Local directory setting was pointing to a location that dated back to a project I abandoned 6 months ago and learned that that path was stashed in $HOME/.config/pharo ... I've finally found the cycles to work on the Pharo portion of my project. I've deleted the whole $HOME/.config/pharo and re-downloaded a fresh set of image and changes files (the previous image and changes files had been polluted by the previously cached values) and discovered that the act of starting the image automagically populates the System >> local directory with a full path to a directory in my current directory ... which is not quite as bad as pointing off to a "local directory" located in "outer space" ... but I assume that I will have the same problem that I had before[2] which is a walkback when attemptingÂ to use the .image file on a machine where the saved local directory path will not exist (similar stack BTW as already reported against pharo in this bug report[3]. What I want to do is create a Pharo.image (i.e., load some code into the image) in such a way that I can ship the image file to users on a completely different system and have them successfully execute the code in the image ... I assume there is a way to do this, since the images I download don't suffer from this problem ... I naively cleared the Local directory field in the system browser, saved and quit the image and then got this error: which is presumably a relative of this error[3]. I used the folder icon to select my local directory again ... saved the image and restarted only to get the same walkback: Keep in mind the ultimate goal ... shipping an image to another user and making it possible for them to use it ... Thanks in advance for any help, Dale [1] http://forum.world.st/where-are-system-settings-stored-td5101501.html [2] https://travis-ci.org/dalehenrich/st_launcher/builds/561863077#L603 [3] https://github.com/pharo-project/pharo-launcher/issues/37

Available to join a project

by Sebastian Sastre

Hi guys, Iâve finished a contract and in the next weeks, Iâll be exploring opportunities to join a new project. Lately, Iâve been working with JavaScript full-stack and docker, AWS, GCloud among other things. By the way, some of the microservices I ran in AWS are deployed as dockerized Pharo images set up as auto-scalable in ElasticBeanstalk. So, after lots of JavaScript and TypeScript, now Iâm curious about joining a Smalltalk project :D You might remember me for trying with Airflowing, this SaaS startup built on Seaside which unfortunately didnât fly far enough but had thaught me LOTS of lessons and made me solve lots of interesting problems with Smalltalk. Let me know if you want to chat to see if I could help with your company/project! You can write me to: sebastianconcept(a)gmail.com Sebastian Sastre More about my developer story here: http://sebastiansastre.co <http://sebastiansastre.co/>

Re: [Pharo-users] Warning Newbie Question: Bootstrap Navbar example works my copy and paste fails?

by Esteban Maringolo

You're using the Bootstrap 4 library and methods. I don't know about the one referenced in the MOOC, but there are several differences between Torsten's Bootstrap 3 (TBS prefixed classes) and Bootstrap 4 (SBS prefix), in particular because Bootstrap 4 library wrapper uses a subclass of WAHtmlCanvas where all the methods are implemented. See if your component implements #rendererClass it should return SBSHtmlCanvas as its renderer class instead of the default, inherited, WAHtmlCanvas. Regards, Esteban A.

Re: [Pharo-users] Warning Newbie Question: Bootstrap Navbar example works my copy and paste fails?

by jtuchel＠objektfabrik.de

Ian, the first thing to do (imo) is to look for implementers of #navigationBar. I would guess there is none to be found in your image. That would mean you most probably don't have the code required for Seaside/Bootstrap loaded into your image. I am not a Pharo user, so I cannot tell you exactly how to load Seaside-Bootstrap in Pharo, but I am sure this is relatively easy to solve by the help of either Ecosia/DuckDuckGo/Yahoo or some Pharoer on this list. The steps to follow: 1. See if the method is implemented somewhere in your image 2. Try to find out whether your are sending Â Â Â a. the wrong message to the right object Â Â Â b. the right message to the wrong object Â Â Â c. a message that should be understood by the reciever but isn't I guess a) and b) can be excluded in your case, your code looks good to me. So the problem seems to be c). I am pretty sure the Seaside-Bootstrap package is missing in your image, it adds extension methods to WAHtmlCanvas, and I guess #navigationBar is one of them...

Warning Newbie Question: Bootstrap Navbar example works my copy and paste fails?

Hi All, Hopefully this is an easy one? I have been going through the MOOC exercises and have come across something I can't seem to figure out. In the example the code reads: ---- renderExampleOn: html | bar id| id := 'navbarSupportedContent'. bar := html navigationBar. bar beLight; expandLarge. bar background beLight. bar with: [ html navigationBarBrand: 'Navbar'. ] ---- Mine reads exactly the same but errors in the browser with: ---- Seaside Walkback MessageNotUnderstood: WAHtmlCanvas>>navigationBar Debug Proceed Full Stack Possible Causes you sent a message this type of object doesn't understand Stack Trace thisContext WAHtmlCanvas(Object)>>doesNotUnderstand: #navigationBar self a WAHtmlCanvas thisContext VIHeaderComponent>>renderContentOn: self a VIHeaderComponent thisContext WARenderVisitor>>visitPainter: self a WARenderVisitor thisContext WARenderVisitor(WAPainterVisitor)>>visitPresenter: self a WARenderVisitor thisContext WARenderVisitor(WAPainterVisitor)>>visitComponent: self a WARenderVisitor ---- When using Finder to locate the selector, navigationBar, I notice that it is a selector of SBSHtmlCanvas. So my question is: How to I set up my rendering class in seaside properly? Currently, as per all I can find I am properly using WAComponent as application super class. I don't see anything in the seaside book regarding bootstrap and I am fallowing the MOOC section on bootstrap almost to a tee. Accepting the fact that the library is now SBSDeploymentLibrary rather than TBSDeploymentLibrary. Any help would be greatly appreciated. Kindly, Ian

Thanks Richard for your review of the article and your pedagogical explanations. For me writing these interactive documents are not that much work. But it is true you need to know the DrGeo API. Which can be discovered by exploring the DrGeoSketch class. I am used to the DrGeo API, so my view is biased. A more user discoverable programming interface will be easier. So the interest on Trygve work. I am finishing writing a textbook on DrGeo math programming for my middle high school students.
