Never-mind folks. Turned out to be a simple bug, my menu-items word did
not correctly return the items of the menu passed in.
Fixing that solved my issue :)
Thanks,

Hi,
I'm trying to use the models vocabulary in order to implement keyboard
navigation on menus. I still have some work to do, but right now I have
something like this:
:: prepare-menu ( menu -- )
f :> model
menu menu-items :> items
items [ model add-connection ] each
model

This is planned. The first step is to get the SIMD primitives worked
out, after that we can start writing higher-level
Hi,
Is there any support currently, or a plan to support, vector words using
SIMD on alien arrays? It seems there's currently only support for using
these words with explicitly register-sized vectors. When I hear of
SIMD, though, it's usually in the context of operating on large
datasets. It

Here is a function that I wrote:

The idiom for = is that the result is eventually consumed by a case.
For example:
: do-something ( n m -- )
= {
{ +lt+ [ Less ] }
{ +gt+ [ Greater ] }
{ +eq+ [ Equal ] }
} case print ;
With locals, you can implement this ?sgn combinator in terms of case as this:
Hi, all
I'm study C library interface, viewing cairo/ffi.factor, then I have a
question:
Is there a tool to convert *.h to ffi.factor, like :
cairo.h:
typedef struct _cairo_matrix {
double xx; double yx;
double xy; double yy;
double x0; double y0;
} cairo_matrix_t;
No, there's no tool like that. Such a tool would be a lot of work,
since it would involve implementing a C header parser and preprocessor
in the general case. This has been done in the SWIG project, I think,
but no one has done this for Factor's FFI. It looks like it'd be
possible to bind to SWIG
Thank you Daniel, I will try SWIG first.
Cheers

Is the length of 'color-map' being computed each time 'color' is called?
In versions of the code that I was experimenting with, I factored out the
color selection part:

In vm/primitives.h, I read:

stack_chain being global, in which case could an assignment
re-ordering occur? (the compiler doesn't know if it will be used in
subsequent functions, so
Hi,
I use a file profile.factor that looks like this:
REQUIRES: libs/httpd libs/furnace ;
USING: httpd threads ;
[ 8889 httpd ] in-thread
Then I run Factor as follows:
screen ./f factor.image profile.factor
Once screen starts, I detach it. Later on I can attach to the screen
and reload
