btw, SegmentIO seems quite impressive aggregating a huge number of services. How have you found the extra level of indirection in practice? how has your experience been with the sources you've tried? cheers -ben On 6 December 2017 at 06:06, Ben Coman <btc(a)openinworld.com> wrote: > Thanks Paul.

dependent magritte descriptions
by Peter UhnÃ¡k Dec. 6, 2017

Dec. 6, 2017

Hi, I'm trying to get dependent magritte descriptions, but it seems like this is not something that can be done in the descriptions: Imagine a class Contact with "city" and "country" descriptions. I would like to populate the city description based on the currently selected country ~~~~~~~~~~~~~~~~~~~~~~ descriptionCountry <magritteDescription> ^ MASingleOptionDescription new accessor: #country; label: 'Country'; options: self countries; yourself descriptionCity <magritteDescription> ^ MASingleOptionDescription new accessor: #city; label: 'City'; options: (self citiesInCountry: self country); yourself ~~~~~~~~~~~~~~~~~~~~~~ The problem with this approach is that both descriptions are in the same form, so I need to update the cities list even before the country is saved back into the object. Is this possible in magritte? Thanks, Peter

Anyone dealt with SignalR before, can comment on implications for access from Pharo? Its originally a Microsoft layer on top of Websockets but there also exist Javascript and Python libraries. https://en.wikipedia.org/wiki/SignalR https://www.quora.com/What-is-the-difference-between-web-sockets-and-signalR cheers -ben

Hi, Here is an update of the work on Bloc and GT: Bloc: - Bezier curves (cubic and quadratic). https://twitter.com/feenkcom/status/934765444464021504 https://twitter.com/feenkcom/status/934856909001252865 - Dragging is now possible through a BlDragHandler that can be attached to any element. - Pixel accurate line heads and tails https://twitter.com/feenkcom/status/936704646290305025 - More flexible scalable element. https://twitter.com/feenkcom/status/934003681539907585 - Improved scalability of the rendering. For example, on Mac, we are on par with the speed of Firefox. https://twitter.com/feenkcom/status/931462535861108736 - Sparta is now able to load custom fonts. https://twitter.com/feenkcom/status/930919637214285824 - Text insertion works now much better. Deletion and Selection still require more work. - The rope data structure can now be better inspected. https://twitter.com/feenkcom/status/937298739584172032 - Sparta/Moz2D has a visual loader that also provides more specific details in case of errors. https://twitter.com/feenkcom/status/936501909581688832 - Moz2D is now installed by default on Linux 64b. GT: - The GT Visualizer sub-project now contains two tools: -- GT Mondrian is a graph visualization engine that is both performant and shows how Bloc works well for visualizations. More details in a follow up post. https://twitter.com/feenkcom/status/937682660704563202 -- GT Connector is a new tool for browsing connected examples. More details about it in a follow up post. https://twitter.com/feenkcom/status/936109463462965248 Enjoy, The feenk team -- www.tudorgirba.com www.feenk.com "If you can't say why something is relevant, it probably isn't."

Tonel + Metacello
by Hilaire Dec. 4, 2017

Dec. 4, 2017

Hi, In a configuration, how are we supposed to use Tonel package? Indeed the Tonel only old the most recent package version, versioning is done at an outer lever by the used CVS system. For now, I have baseline and configuration as: baseline1801: spec Â Â Â <version: '18.01-baseline'> Â Â Â spec for: #common do: [ Â Â Â Â Â Â spec blessing: #baseline; Â Â Â Â Â Â Â Â Â repository: 'tonel:///home/hilaire/Travaux/Developpement/DrGeoII/trunk/src'; Â Â Â Â Â Â Â Â Â description: 'Dr. Geo, an interactive geometry application.'; [...] version1801a: spec Â Â Â <version: '18.01a' imports: #('18.01-baseline') > Â Â Â spec for: #common do: [ Â Â Â Â Â Â spec blessing: #development. Â Â Â Â Â Â spec description: '18.01a'. Â Â Â Â Â Â spec package: 'DrGeoII-Core' with: 'DrGeoII-Core'. Â Â Â Â Â Â spec package: 'DrGeoII-Polymorph' with: 'DrGeoII-Polymorph'. [...] Of course absolute path in the repository field is far to be desirable. What is your best practice? Hilaire -- Dr. Geo http://drgeo.eu
