It's particularly disconcerting when using parsing words like R", which do require the space. Since in the standard library there are only 6 words containing ", I propose the following parsing change: Treat " as end of word. This would generalise quotes so that we can write R".*", which to me is a lot less confusing than R" .*". I don't believe anyone would write a word named R"blah", because of how confusing that looks. Would this be worth implementing?

The locale is forced by gtk to the environnement variables. However, the old X11 backend also forced the locale (in basis/x11/x11.factor) so this is should not be new with the gtk backend.. So I guess the best solution is to force LC_NUMERIC to a locale that has a "." as the numeric separator right after gtk_init (for example set_locale LC_NUMERIC "C"). Here's a patch that does that: http://paste.factorcode.org/paste?id=2595 Please feel free to modify/improve the patch...

I've built a couchdb 1.2.0 database, and sucessfully replicated it via curl (command line) back &amp; forth between my localhost cdb instance and Cloudant and Iriscouch hosts. But when I try to POST a _replicate command from Factor, I've found no way to avoid an immediate closed connection and retry (terminal msg), followed by an I/O timeout error (listener). Looks like this: ! sample Factor code; starred* words just alternates of couchdb vocab (except set-keep-alive*) : set-keep-alive* ( request -- request ) ! pipeline fiddling with headers "keep-alive" "connection" set-header "cwalston" "password" set-basic-auth ; : couch-http-request* ( request -- data ) set-keep-alive* !

There was no change. I checked out the blogs from Planet.Factor and noticed that all but 1 seemed to have no additions for about a year. It prompts me to ask if Factor is dead and if there will ever be a version 1? ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.

However, when trying to write simple words I get stuck on how to best express dataflow. As a (very very simple) example, I am trying to write a word : swap-element ( i1 array1 i2 array2 -- ) that swaps two elements with indices i1 and i2 from 2 (aliased or not) arrays. It is very easy to write such a word using lexical variables. However, I have two problems with that: - I am not sure it is the right tool to use or just my brain bringing me back to what I know. - It does not show the symmetries of the dataflow of this word I quite like the style of something along the lines of: : swap-element ( i1 array1 i2 array2 -- ) [ [ nth ] 2keep ] 2bi&lt; at &gt; ???? [ set-nth ] 2 smart-apply ; because it shows the dataflow better than with lexical variables. But I can't find something nice to put instead of ????. So, I guess that my question is: how to solve this problem and, more importan</pre> nicolas.oury-Re5JQEeQqe8AvxtiuMwx3w< at >public.gmane.org 2012-03-12T13:00:34 http://comments.gmane.org/gmane.comp.lang.factor.general/5797 <pre>I solved Windows-specific installation issues I had with Factor, and now I have moved on to playing with Factor. I thought I would best learn it by trying to accomplish a work-related task with it instead of just trying to rewrite some previous python code. Anyway, I have a CSV formatted file that has been exported from an Excel file. The original Excel sheet was laid out like a horizontal form, so there is no easy relationship between headers and rows. Please forgive me, and tell me if I should put the code or file snippet elsewhere, and I will do so in future posts. Here is a sample of the CSV output: "Show Report",,,, I simply wanted the value right after Show Date: 24/02/2012, Ticket issued: 1029 and Total Attendance 998, like so: 24/02/2012,1029,998 I don't need headers. Here is the code I have been using in the listener: USING: io.encodings.ascii io.encodings.utf8 regexp csv This gets me 95% of the way there, but it is surely not the cleanest or Factor-like way to go.

When simply scrolling through content displayed on browser windows (created by pressing both the Help button on the Listener window and invoking the browser-window word) Factor will crash: all of the windows disappear and everything's gone. I have confirmed this on two different Windows XP machines (both on SP3.) Wish I could give you more information, but that is all I see thus far. And this behavior is not consistent, not as far as I can tell. Is this a known problem with the 32-bit Windows flavors of the Factor binaries? I confess disappointment: I was getting ready to start back in on trying to use furnace, etc, and now the latest stable build for Win32 is unreliable, right on the heels of my personal progress in understanding functional programming well enough to want to give Factor a try again. Please don't tell me that I shall have to confine myself to Haskell when I want to do some elegant functional programming..</pre> Richard Stewart 2012-03-08T21:25:18 http://comments.gmane.org/gmane.comp.lang.factor.general/5790 <pre>Hi! Today I was trying to write some factor code and it turned out that I can write such code: *1 5 4 3 2 [ 5 = not ] loop* It works and produces stack with one element 1. I expect that at least I would have a warning because loop word takes quotation with ( ... -- ... ? ) stack effect. In the example I use quotation with ( x -- x ) stack effect. So what I am missing?

I'm currently deeply fascinated by lisp and forth for some reason, and with Joy being at risk, I decided to take a dab at factor. I downloaded the source during the weekend from git and used the build-support/factor.sh update, which went just fine on my x86_64 debian-unstable box. However I cannot run the bunny and terrain examples. They fail with a segfault: Memory protection fault at address 7f2adb2b90b0 I'm just trying them at work here and I have the same issue, so maybe there is a problem with the examples themselves?

I think this contains too much programming stuff, making it hard to read compared to the Haskell version: receptionPerHead = 60 receptionAttendants = 50 reception = receptionPerHead * receptionAttendants venueHire = 2800 total = sum [venueHire, reception] So what I did was make: SYNTAX: D: CREATE-WORD parse-definition (( -- x )) define-declared ; so the factor code now looks like: D: receptionPerHead 60 ; D: receptionAttendants 50 ; D: reception receptionPerHead receptionAttendants * ; D</pre> Luke Worth 2012-02-20T12:19:24 http://comments.gmane.org/gmane.comp.lang.factor.general/5770 <pre>A while ago I sent a message to the list, except it turns out that I'd subscribed to the list from a different email address than I currently use as my default, and messages from non-subscribed addresses get held for moderation.

Some questions: 1. What is best win-editor for Factor? Oh no, not Emacs! I mean something like Programmer's Notepad. 2. What is Listener? It can be used as the editor? I open Listener, Browser, Errors... 3. I need some simple program. For example, calculation of a percentage parity of numbers. Input data: 1, 2, 3. Output data must be 0.167, 0.333, 0.5.
