I like the idea. I wonder how you resolve dependencies & failures.

[Pharo-project] Process questions about configurationOfâ¦.

by StÃ©phane Ducasse

Hi guys What is the process we want? What I would like is MetaRepoForPharo13Inbox were everybody can write and a jenkins process that loads every published version and try to load it (after we will run tests and check rules). depending on the result the configuration is promoted into MetaRepoForPharo13 or MetaRepoForPharo13Broken At the end of the month we will have one engineer working on jenkins and I would like to ask him to start to put in place this process. What do you think? Stef

I would also disable eCompletition in Settings by default until it works smart enough, which currently not. I agree with Ben here and I also disable it immediatelly.

Re: [Pharo-project] Smart bracketing annoyance

by Ben Coman

Thanks Lucas. I am using the stock Pharo-1.3-13315 image and found it under "Code Browsing > OCompletion > Smart Characters" Although I do like the concept (I often do the same manually) I need more control of when its occurs. A ctrl-key combination would be ideal. Also whoever is packaging the next version OneClick should consider whether its appropriate to be enabled by default for those having their first experience with Pharo. -Ben Lukas Renggli wrote: > For the "smart" bracketing: Either do not load eCompletion, or change > the settings in "Code browsing > eCompletion". > > For the indention press Ctrl+Shift+L and Ctrl+Shift+R. > > Lukas > > On 7 January 2012 09:29, Milan Mimica <milan.mimica(a)gmail.com> wrote: > >> I'll just hijack here: I also wouldn't be totally uncool if you could select >> a block of code an press (shift-)tab to (un)ident it.

Re: [Pharo-project] happy new year plus cogdroid news

by Guido Stepken

Hi Alain! Google has unified development for handy and tablet 4.0. They have introduced scalable, animated tiles, reacting on events, coming from analysing contents of about 100 different protocols streaming through the machine. Google even collects barometer and temperature information global, for own weather forecast, and A-GPS information for traffic jam maps. This new tile approach is even intended to be introduced onto desktops, so i fear, former designs with pulldown menus will look old fashioned in about one year for customers, included Windows 7, Mac OS X. This new tile design even can be found already in Samsung TV's. Like Jobs banned flash on iphone for power consumption disadvantages, Google has dropped the "monolithic" design approach and invented a "multi-vm-vm", where multiple bytecodes are executed in parallel, but time slices are controlled by the underlying linux scheduler. This approach leads to very good uptimes of your handy or tablet. 1/2 Watt incl. Display at normal operation. So, any "monolitic" vm will consume too much power. Pharo Smalltalk completely had to be redesigned to work on multi-vm-vm, where parts of smalltalk code can be time scheduled by the underlying kernel. Apart from the fact, that about a hundred new protocols had to be implemented in pharo, i see NO chance in integrating pharo in the new operating system designs. This is state of development on vm's . And yes, jitter included.

For the "smart" bracketing: Either do not load eCompletion, or change the settings in "Code browsing > eCompletion". For the indention press Ctrl+Shift+L and Ctrl+Shift+R.
