Some Spotter Questions
by Sven Van Caekenberghe Jan. 31, 2016

Jan. 31, 2016

Hi, I managed to add a spotter extension and preview, but I still have some questions. Is there some global top level overview documentation about writing Spotter extensions ? Is the only way to add a 'global/first' search extension by adding a method to class GTSpotter itself ? I don't see any other package do that (in a modular way), it feels a bit wrong compared to how modular the GT inspector is. Is there a way to reuse a GT inspector view as a preview ? I tried that but it did not work, but what I copied over was 99% identical. Can you have tabs (multiple pages) in the preview ? Is it possible to control on what tab an inspector opens when a matching item is clicked (like to maintain the same view as the preview) ? What are some best practices for the order, exact matches, fast searching, etc ... ? Is it possible to search in multiple ways (multiple properties), not just collection -> itemName -> GTFilterSubstring ? (Say I want to search all fields of an address object). Searching for Color by name, or by RGB and other representations would seem like a good tutorial example (for me). Thx, Sven

Use cases for methods with optional parameters
by Damien Cassou Jan. 29, 2016

Jan. 29, 2016

Hi, I would like to study the impact of adding optional parameters to keyword methods in Pharo. The goal of optional parameters is to facilitate the implementation of methods where some parameters are optional. For example, Seaside has: WAComponent>>request: aRequestString label: aLabelString default: aDefaultString onAnswer: aBlock ... This method of 4 arguments has only 1 required argument (aRequestString) and 3 optional ones. In the current implementation, this results in 7 additional methods that only delegate directly or indirectly to the one above: - request: - request:default: - request:default:onAnswer: - request:label: - request:label:default: - request:label:onAnswer: - request:onAnswer: Before starting to implement anything, I need to know if it makes sense. If you want to help me, please send me all the use cases you have by giving me: - the library name (and URL if not in Catalog), or "pharo" if it's in Pharo - the class where this happens - the range of selectors that make sense For the example above, this would be: - Seaside - WAComponent - request:* Thank you very much -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

Windows headless and service
by Robert Kuszinger Jan. 29, 2016

Jan. 29, 2016

Hello Everyone! I'd like to install a Seaside app in Pharo in Windows (Server 2008). I live on linux but now I must put it on Windows. Pharo --help pops up a window with only a fragment of options. Pharo --headless TheFilenameOf.image Won't do anything. I've checked the available books but they mostly talk about mac osx/Linux which is welcome, anyway... Does anyone have experience with pharo (service) on windows? My version is (from readme): *Pharo 4.0 This distribution was built December 07, 2015.* thanks Robert

Pharo + git workflow
by Norbert Hartl Jan. 28, 2016

Jan. 28, 2016

I'm eager to try a new project with some git repositories. But to be honest I don't really get it. Searching the web there is lots to find but nothing actual. I don't understand if it is ok to use a ConfigurationOf or if it only works with a BaselineOf. And how do you specify the repository in a ConfigurationOf in order to be able to work locally as well as having jenkins pull everything automatically? Same goes for dependent projects. Are there any insights to this or pointers to an up-to-date documentation? thanks, Norbert

CommandLineHandler surprises
by Jimmie Houchin Jan. 28, 2016

Jan. 28, 2016

Hello, I am reading the Deep Into Pharo book. I have been playing with the CommandLineHandler. I have been surprised by some of its behavior. Though I have used Pharo a long time. I have not played with it from the command line. I am a very long time Linux user and am very comfortable on the command line. When according to the book I execute: ./pharo Pharo.image --list It will provide me with a list of the available handlers. I did not expect it to open up an image for me. That is not what I expected or wanted. I did not intend to use an image at this time. I am on the command line and expecting to see results there. Not for a new window to pop up. As of yet I have always opened up Pharo on the command line. I have yet to use PharoLauncher, but do intend to do so soon. So I am comfortable with Pharo opening up a new window and image from the command line. However it is very unintuitive and seemingly unnecessary to open up an image for these command line handlers. I naively think they should simply return the results. Now if that requires opening a headless image for a moment and close, then fine. --list --help --version --copyright eval printVersion Some other handlers I do not know if opening an image is the correct default. I have not spent the time learning them yet. Thanks. Shalom Aleichem. Jimmie
