Re: [Factor-talk] some code for a file explorer
Hi John, cool, I'll try and get something ready asap. Best, Manuel Quoting John Benediktsson mrj...@gmail.com: Hi Manuel, When you get this working, even as just a demo, it might be nice to include in the Factor repository. Best, John.

Bye, Manuel Quoting Jon Harper jon.harpe...@gmail.com: Hi Manuel, add-connection is used to implement new controls. If you wanted to display the current selection in another window, then just creating a label-control from the selection model would be enough: the label-control gadget calls add-connection and activate-model on its own. Also, models and control are most useful when you want a computation (for example UI update) done every time the data changes (through add-connection). Also they implement some kind of laziness because some computations are only done if an observer has activated the model (for control gadget, this is done when they are visible on screen, through activate-model). For just copying the data when the user presses the select button you don't need the features of models. You can just grab the value of the selection model at the time the user clicks the button. How about having the same behavior when the select button is clicked as when enter is pressed or when double clicking a row ? The following diff passes a reference of the table to the quotation called by the button and executes row-action on it: http://paste.factorcode.org/paste?id=3120#1420 Cheers, Jon -- Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.

Re: [Factor-talk] Presentation and installation issues on Slackware64-14.1 Linux
Hi Luis, 2013/12/10 Luis P. Mendes luisl...@gmail.com: Here are some benchmarks (posted by the author of Factor?) comparing Factor against V8, LuaJIT, SBCL, and CPython: http://factor-language.blogspot.com/2010/05/comparing-factors-performance-against.html http://shootout.alioth.debian.org/ contains more benchmarks for more programming languages(including C++). I know about http://shootout.alioth.debian.org/, but Factor is not one of the languages being compared. I believe Factor does very well in various benchmarks. Factor code is not run inside of a VM, like Python or Java (which has a JIT, yes) and is instead compiled to native machine code so it has the potential to be very fast. But it really isn't that important. Factor's Alien library makes it very easy to write cross-platform wrappers for shared libraries. It's analoguous to ctypes in Python but better. So in a large project it would be trivial to write the most performance intensive functions in C and the rest of the application in Factor. Factor already comes with a wrapper for BLAS if you need fast numerical computation, for example. After some more digging into the language, Factor does really feel like a very good language. But after some more searching, in http://planet.factorcode.org/ and the blogs pointed there, I come to realize that it seems that developers don't earn their living using Factor, except maybe for Slava Pestov. There are some C++, Java, and some discussions about incursions in other languages like Self. So, my question is this: is Factor really meant to be used in real world business applications? Do developers and main contributors really believe in this possibility? I'm just a Factor newbie, but sure why not? Right now, not many people use Factor because it is not marketed much and it still has some minor blemishes. Many people like functional programming which Factor excels at so I think it would be possible that more people will become interested in it. -- mvh/best regards Björn Lindqvist -- Rapidly troubleshoot problems before they affect your business.
