Nice investigation. This should go in the docs somewhere, particularly that parents gadget must pass gestures to the parent for the actions to work. For example in http://docs.factorcode.org/content/article-action-gestures.html ? diff --git a/basis/ui/gestures/gestures-docs.factor b/basis/ui/gestu

[Factor-talk] gcc versions

Hi, for info, we can't compile the factor vm with the default compiler (gcc 4.7.2) of debian oldstable wheezy anymore. First, it has a false compilation error ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54277): g++ -c -x c++-header -Wall -DFACTOR_VERSION="0.98" -DFACTOR_GIT_LABEL="heads/master-

Re: [Factor-talk] Why does number>string append ".0" on my German system ?

So I looked into this, trying to solve it by calling printf through the FFI with a locale setup and cleanup. The difficulty comes from the fact that printf is a variadic function.. Factor's ffi doesn't support them, at least no in a cross platform manner, right? So a workaround could be to wrap p

This is being fixed. Meanwhile, you can adjust your locale settings to workaround: LC_CTYPE=C ./factor Should work. If not, you can try LC_ALL=C Jon Le 11 août 2015 9:30 AM, "Georg Simon" a écrit : > IN: scratchpad 1.5 number>string . > "1,5.0" > > I would have expected "1,5" > > > --

Hi Doug, so I guess everyone has been teased with all the clues about the new parser :) 1fcf96cada0737 says "something else soon.", https://github.com/slavapestov/factor/issues/1398 mentions it, etc. Could you share your plans for the new parser ? How will it be different, what will it improve, et

This sounds like mixing the features from: - http://docs.factorcode.org/content/article-embedding.html which initializes everything, but then requires the compiler to use a string -> factor eval -> string call. - http://docs.factorcode.org/content/article-alien-callback.html which allows to directl

Hi Mark, can't work with arrows. Among other reasons, in your case the arrow is not activated when it's data is used to intialize the editor string (that's why you see them empty). The model given to model-field isn't meant to be updated by the caller anyway: it's value is used as an initializati
