[Factor-talk] Symlinks
It appears that Factor isn't able to detect file modifications (using
refresh-all) for files that are contained in a directory through a
symlink.
To reproduce:
1) Make a directory my-vocab, with a my-vocab.factor file.
2) Make a symlink from inside of work to that directory.
3) Confirm that USE: my-vocab loads properly from ${FACTOR}/work/my-vocab.
4) Change something inside of my-vocab.factor.
5) Try to refresh-all, and see that it did not pick up the changes.
If there is something I'm missing, please let me know?
Thanks,
John.

By the way, I don't get any usage info for Factor that would list the
-script option. (no factor -h, factor --help, etc.) Is there a getopt for
Factor?
I think -script was a relic of the past; it doesn't appear to be
necessary anymore. The main remaining caveat with #! is that it needs to be
followed by whitespace.
There might be a getopt-like parser library, but I don't know of it.
Maybe someone else does. However, the VM will parse options of the form -foo
or -foo=bar and set them as variables in the global namespace for you, which
you can access with the get function. For example:
$ ./factor -foo -zim=zang -flux=rad
( scratchpad ) foo get .
t
( scratchpad ) zim get .
zang
( scratchpad ) flux get .
rad

Re: [Factor-talk] sequences and the stack
Also, for your case a sequence of two elements can be treated a bit like a map
of key/value pairs. You can use the assocs vocabulary to manipulate your
sequence (called an association list or 'alist' in the documentation).
Try:
( scratchpad ) USE: assocs
( scratchpad ) \ assoc-map help
( scratchpad ) \ assoc-each help

Subject: [Factor-talk] sequences and the stack
The stack contains a sequence of number pairs:
{ { x1 y1 } { x2 y2 } { x3 y3 } ... }
I want to map over the pairs, accessing xi and yi.
[
! stack = { xi yi }

What's the code that goes in !... ?
Other than using nth, how can I do this? Is there a word that pops the

Re: [Factor-talk] traslation
Well, here's three versions for inspiration.
1) Given a 'foo' quotation that takes elements from each and prints it out:
: foo ( a b foo: ( x y -- z ) -- )
[ with map join print ] 2curry each ; inline
( scratchpad ) { 1 2 3 } { a b c }
[ append ] foo
2) Given a 'foo' and a 'bar' that acts on the resulting sequence from
'foo'ing:
: bar ( a b foo: ( x y -- z ) bar: ( z -- ) -- )
[ [ with map ] 2curry ] dip compose each ; inline
( scratchpad ) { 1 2 3 } { a b c }
[ append ] [ join print ] bar
3) Taking version #2 and rewriting with fry quotations:
USE: fry
: bar ( a b foo: ( x y -- z ) bar: ( z -- ) -- )
'[ _ with map @ ] curry each ; inline

Re: [Factor-talk] Metadata
I don't think versioning the vocabularies included in Factor is necessary. You don't see versions in standard libraries of other languages. However, it would be nice if released versions of Factor reported their version numbers properly. On Aug 27, 2011, at 12:32 PM, Matt Gushee m...@gushee.net wrote: Hi, all-- I'm wondering what the Factor community would think of including certain kinds of metadata in the source code for vocabularies and for the Factor itself. My starting point for this line of thinking was that I had played with Factor for a while a couple of years ago, then dropped it for a while ... and I wanted to know what version I had installed. So my first thought was to go to the listener and try version Nope. Okay, how about factor-version ? No again. And so on through several variations ... nothing. Nor could I find anything in the online help. Nor any file in the source directory to indicate the version (or revision date). And it occurs to now, which should be obvious, that I can probably use Git to find out some pertinent info. However: * Not everyone is using Git. * Version info is useful, not just for the purpose I mentioned, but also for debugging. * It seems desirable to be able to query version info via the listener, and probably also programatically for the purpose of checking dependencies among vocabularies. Furthermore, there is probably other metadata that would be a good idea to maintain. For example, if Factor becomes widely used, there might be a situation where different developers distribute similarly- or identically-named vocabularies. So we should have the developer's name, or email address, or some other identifier that serves to distinguish a given vocabulary from a different one with the same name. Personally, I feel pretty strongly about this; if I were in charge of development I would make at least the above-mentioned items *mandatory* for all language components, such that a vocabulary would fail to load or compile if it didn't include the required metadata. But I think I've said enough. I will leave it up to more experienced folks to decide whether and how to implement this idea.

As a newcomer, I have to agree somewhat. It's frustrating when examples from Help don't work because Factor has changed since the help was written. However, even with errors (inconsistencies?) Factor's Help system is very useful. What examples from help do not work? Generally all the examples you find in Factor's Help (or on docs.factorcode.org) should work.

Keep in mind that tools.test is largely used for unit tests (-tests.factor files) and the help vocabularies are used for documentation (-docs.factor files).

I hate Graphviz. I really, really do.
I'm not sure about the kernel-error, but if the unexpected quitting is
anything
like previous issues I've come across, their source code habitually calls
exit(), which kills the UI listener since they share the same process (I
experimented once with forking the FFI calls, but that's a no-go on
Windows,
so). If you -run=listener to test, you might be able to see if a message
gets
printed by Graphviz to stderr. Maybe that'll give us more info?
(If it's further similar to other problems I've had with Graphviz, the
error
message will be a single line buried in some undocumented corner of some
messy
source code that hasn't been discussed anywhere that's indexed by Google.
Joy.
I hope for Graphviz's sake that I'm just really incompetent at reading C
code.)

Finally getting around to developing my first serious Factor code and I

mostly my own bastardized version of Forth). I'm thinking of one immediate
use of Combinators as a way of eliminating some of the unsightly procedural
code that lives in the kind of Forth function I would write inside of, say,
a Begin While Repeat loop.
But if what I would have wanted to do with my loop is loop through every
item in a collection of some sort until some condition was true and at that
point exit the loop early, is there a way to do this using Combinators? Are
there versions of the primary ones that will operate on the target sequence
only until a condition is reached? I will of course peruse the
documentation, but I thought I would just ask in case someone could steer me
there more quickly (and in case some other newbie has the same question).
Thanks much.

Well, you could do this:

If you want to check the stack names in the effect, you can do this:
: my-effect= ( effect1 effect2 -- ? )
{ [ effect= ] [ [ in ] bi@ = ] [ [ out ] bi@ = ] } 2 ;
( scratchpad ) all-words [ stack-effect (( x p q -- ) my-effect= ]

Factor programs are often short enough to fit on a few lines, you can type

Programming in a concatenative language is very different. You certainly
don't want to think in terms of variables and assignment. Instead, think
about the intermediate results you want, and how to put them onto the stack.
In this case, the relevant result is the sum of the list, but you also need
to keep the original list around. After you have those two, you divide. Using
the math.vectors command v/n (vector divided by scalar), we get
{ 1 2 3 } ! the list
dup! make a copy of the list
length ! get the length of the copy
v/n ! divide the two
Words like dup are only suitable for very simple tasks since they are
confusing when used excessively. Instead, the combinators cleave, spread,
apply and their derivatives like bi, bi*, tri@, etc. should be used. The
listener prints the stack effect of each command at the bottom, so if you
forget which one is which, you can type them in and see. In this case the
program becomes
{ 1 2 3 } [ ] [ length ] bi v/n

Re: [Factor-talk] Learning Factor - string, array and io handling - beginner
I am unsure how to check for an empty string and skip it if it is empty.
empty?
I have been unsuccessful in getting it to write to a single file in an append
mode, or to create a sequence of files as it goest through 'each'
'with-directory-files'.
/tmp/foo ascii [ hello world print ] with-file-appender
The people who have entered the data mixed mm/dd/ with dd/mm/ in the
original Excel sheets that I created my CSV sheets from. Of course it is easy
to check for numbers 12, but dates like 10/10/2010 are problematic.
I had to use file-lines vs. filecsv to bring in the data, or else I could
not get my regexp working on the CSV from filecsv.
The csv vocab makes sequences of strings. The regexp vocab only works on
strings.
IN: scratchpad a,b,c stringcsv .
{ { a b c } }
You might want to look into words like find, find-from, or other sequence
operations if you want regexp like searching or matching.
Not really an issue, but are there any cominators or other commands that
could consolidate all of the 'swap drop swap' commands I have resorted to
using. Or 'first second' commands? I wish there was more Factor code out
there on the web to learn from...
Well, swap drop swap is nip swap. But often when you are using stack
shuffling words, you are not taking advantage of higher level words or
combinators. Try reading:
IN: scratchpad combinators help
Also, you might find this blog post I wrote on refactoring a word that has ugly
stack shuffling to be useful:
http://re-factor.blogspot.com/2010/05/evenly-partition-integer.html
resource:work/thodw/data [
[
utf8 file-lines
[ R/ Date|Ticket|\Show Time:\/ re-contains? ] filter
dup
0 swap nth stringcsv
first second 10 cut swap , append
swap drop swap
dup
1 swap nth stringcsv
first second 5 cut swap , append
swap drop swap
2 swap nth stringcsv
dup
first second , append swap
first 4 swap nth
3append
append
print
#! utf8 csvfile
] each
] with-directory-files
You might find something like this makes it cleaner:
utf8 file-lines
[ regexp ] filter
{ 0 1 2 } swap nths
[ stringcsv ] map
Also, if you are appending and then printing, you can just write the strings as
they happen, or try looking into the make vocabulary:
[ Hello % CHAR: \s , World % ] make .

John.

Btw, your patch is linux specific for those constants, on OS X, locale.h has this: #define LC_ALL 0 #define LC_COLLATE 1 #define LC_CTYPE2 #define LC_MONETARY 3 #define LC_NUMERIC 4 #define LC_TIME 5 #define LC_MESSAGES 6 #define _LC_LAST7 /* marks end */ On Mon, May 21, 2012 at 9:13 AM, Jon Harper jon.harpe...@gmail.com wrote: Only allowing . seems a lot simpler. If we use the locale dependant decimal point when we print numbers, what should we do when parsing numbers ? If the parser also uses the locale decimal point, then source code compiles differently depending on the locale.

Re: [Factor-talk] Would anyone like to review a program by a beginner?
Welcome! I would be glad if someone could look at the source and tell me what beginner mistakes I made. https://github.com/tohava/cpuguard/blob/master/cpuguard.factor You might find your code looks nicer if you use wrap text at 72-80 character lines, for long words you can put the contents of the word on the line following its stack effect. This is a convention that the factor codebase uses generally. Some feedback: 1) Since objects that are not f are considered true, you don't need to use boolean in your numeric? word. 2) In tokens, the code ``[ = not ] filter`` is pretty much the same as harvest. 3) In the stack effect for if*-empty, you might use true and false for the quotation names instead of quott and quotf (or perhaps true-quot, false-quot). 4) Generally, the factor convention prefers dashes to underscores (e.g., pid-file instead of pid_file). 5) In limits_with_pids, you can use sift instead of ``[ ] filter``. 6) Sometimes there are simpler stack shuffling you can do, instead of this: [ arr1 ] [ arr2 ] bi pick swap [ nth ] 2bi@ You might try this: [ arr1 over ] [ arr2 ] bi [ nth ] 2bi@ Or even this: [ arr1 nth ] [ arr2 nth ] bi-curry bi 7) You can use the private namespace to keep words that you are only used by your vocabulary and not anticipated to be used by anyone else. Surround the words that are private with PRIVATE and PRIVATE. See this for more information: http://docs.factorcode.org/content/article-word-search-private.html 8) Using fry and some combinators can simplify words, for example: : update_arr2 ( arr2 pids -- ) [ dup pid_and_total_time swap stringnumber pick set-nth ] each drop ; Could become this: : update-arr2 ( arr2 pids -- ) '[ [ pid-and-total-time ] [ stringnumber ] bi _ set-nth ] each ; Alternatively, if you keep pids as a sequence of numbers instead of strings, it's even simpler: : update-arr2 ( arr2 pids -- ) '[ [ pid-and-total-time ] keep _ set-nth ] each ; p.s. where is there info about how to run this program as an executable instead of from the factor IDE You should read through these pages: http://docs.factorcode.org/content/article-tools.deploy.html If this is the first time you are deploying a vocabulary as a binary, you can choose deploy options using: cpuguard deploy-tool Alternatively, you can just do cpuguard deploy which uses either defaults or your previously saved deploy settings.

The other way it to use a slow word called with-datastack:

You can also use smart combinators:
[ 2 1 - 3 ] sum-outputs
This works because the quotation infers at compile-time, and
sum-outputs is a smart combinator that expands based on the number
of outputs inferred.
You are trying to do a C varargs function, basically, and just as in

P.S. Incidentally, while I am on the subject, I find myself able to trace through the VM startup code in Visual Studio with no problem at all, until I get to the factor_vm::c_to_factor, which wraps a c-to-factor sub-primitive inside of a callback stub and then invokes that function. On both a Windows 7 platform and a Windows Server 2008 platform, my Visual Studio blows up when the callback address loaded into EDX is called. Anybody ever encountered this and any idea how to get around it? Factor code doesn't follow the C calling convention so it's unlikely that a debugger will be able to walk a stack with Factor frames. In recent versions of Factor you can trigger Factor's own low-level debugger with ^C, which will let you backtrace and step through Factor frames. -Joe If I'm understanding this correctly, you are suggesting that if I'm in the Factor development environment, I can drop into Factor's own low-level debugger. But what do people do (you language maintainer, for example) when you need to debug the startup code that builds an image that needs to be in place for the development environment even to be launched? Am I correctly understanding you, that I can't use a Windows debugger to step through the init sequence, but don't have Factor's debugger available yet either? Or am I missing something?

Although I realize the bootstrapping mechanism is not a general area of interest to many, I think something on the order of about 25 well-placed comments prefacing some of the more extensive quotations would help improve readability tremendously, just in case someone needs to understand the internals of this mechanism.

Thank you, Joe, for the quick response. It was actually the information in the such as clause of your last sentence that I was looking for.

Re: [Factor-talk] Any way of making sense of what's in the boot image?
that appear occupy two adjacent array slots. But I'm completely mystified as to how the contents of the hash-table got mapped to the array slots they now occupy (there doesn't seem to be any rhyme or reason). And I have little insight into the code that accomplished this. Moreover I apparently can't see the 4th slot of the original object in the Inspector, as it only shows me three slots on the data stack trace, but organizes them alphabetically when I double-click to open the Inspector window. Don't know if any of this was intelligble. But maybe one of you compiler guys can give me a clue as to how I can understand this. I'm having to reverse engineer my understanding of all of this, so a break in the logical chain presents difficulties. Sorry for the long post.

Re: [Factor-talk] Any way of making sense of what's in the boot image?
So then, John, does that mean that in the [ 4 slot { array} declare ],
that I'm getting the slot named array which is at offset 4 (and then
declaring that to be an array, so as to disable some of the type safety
checks)?
Yes, the hashtable code is written at a bit lower level and thus maybe a
little harder to read than one might normally write in Factor since it is
one of the building blocks that everything is built upon. It is also
possible that some of the compiler optimizations that have been written in
the last couple of years make some of those declarations unnecessary,
although I'd have to look into it more to know for sure.
Also, due to the bootstrapping mechanism, some of the higher level language
constructs like locals and fry quotations are not available yet. That is
something we hope to fix at some future point.
Here it says slot takes two incoming values: an obj and a non-negative
fixnum, which is the nth slot. In the hashtable slot-specs you list below
there are only three slots listed, but it does say that the slot named
array is at offset 4. Is it this offset number that is being specified
by the m parameter? And thus is the array I am seeing in my original
description the contents of the array slot of the hashtable that was
originally on the stack? That makes sense to me. And the fact that the
array is 128 slots long (allowing flattened representation of 64 key-value
pairs) just means that the underlying array in the hashtable has 64
buckets. Is this a correct interpretation. If it is, it makes sense that
the actual 26 values stored in the hash table would be dispersed
throught the 64 buckets, because this is what a hashtable does.
Yes, exactly! The slot-spec tuple provides a generic description of what
is to be found in this case at offset 4.
Best,
John.

Any thoughts on the differences? I'll keep you posted, if anything unrecoverable pops up. Thanks so much to all for your work. Onward!

Gracias, John - De nada ;) Comforting to know what's up. Any ideas on what prevents the .95 binary from launching on my aged machine? First time I've encountered this problem. I've successfully launched from incremental development releases through July. Likely related to upgrading to Mac OS X 10.8 and XCode 4.4 on the build farm. It wasn't intentional, but we're trying to figure out if we can make XCode 4.4 build against 10.6 SDK or downgrade to a configuration that will work properly... once we get it working we can make new binaries...

Re: [Factor-talk] Is there a Factor.js ?
Hi Michael, I'm enjoying these conversations and your investigations :) Regarding Javascript, I can see the benefit of a Factor-like language. It might be that using Clojure and Clojurescript as an analogy would be a good one. Obviously some parts may be harder to get compatible when bootstrapping from various JS engines, similar to trying to bootstrap from JVM or CLR. Language interoperability is a nice concept when you can get it working well. Can't wait to here more about your ideas as they develop... Best, John.

In fact that is how I'm intending to target the CLR and JVM in my own environment -- whether I successfully implement the ability to use Factor (the language) inside my platform or not. I was envisioning something like a combination of direct byte code generation (either MSIL or JVM byte code) together with whatever programmatic facilities are necessary for fixing up metadata tokens, invoking the respective jit compilers and the like. This could just as easily be done from the existing Factor environment as any custom environment I manage to construct and in a perfect world Factor code created in either environment would compile and execute in the other just fine. You Factor guru types might be scratching your heads and wondering why on earth I would want to reproduce the factor booting mechanism in my own environment and build it on top of my own foundations instead of just using what Slava has already put so much work into. The answer is that while I'm not sure that this will be necessary (i might be able to get away with the DLL-ized version of Factor itself; I'm in major research mode about it as we speak), I suspect I may need to roll my own in order to integrate at as deep a level as I need with other language facilities I already have in place. That's as much as I'm going to say about it, because I don't want to commandeer the FactorCode.org airwaves to talk about my stuff. But whatever I end up doing, I do expect to give back to the community in the way of documentation of what I learn along the way.

What I'm envisioning is something closer to Microsoft's C++, which now has built-in support for generating MSIL, while still remaining completely viable on a native code platform. Such a capability for Factor (with the ability to generate JVM byte code as well) would allow Factor to act as a DSL layer above real-world code bases that organizations are always going to be using for a significant portion of their development. The JVM and CLR both have native code interfaces a Factor bridge could take advantage of. I think that would be a more realistic avenue toward interfacing with those platforms than rearchitecting Factor to target the JVM or CLR directly. -Joe -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Factor-talk] Modules/packages for Factor
I think there is a danger in proliferation of too many packages with too many versions here. One advantage that Factor has had, albeit a mixed advantage due to reduced resources at times, is one main codebase that can be improved in wide cross-cutting ways. That has resulted in a lot of common vocabulary improvements instead of forks. We should support packages, and versions, and freezing of requirements for your application, but lets not lose sight of the benefits we've enjoyed thus far. As an aside, the CPAN testing infrastructure is something to be copied. Every time someone uploads a new module it goes through various automated testing on different architectures, and produces a build report back to you. That combined with some kind of cross-module lint tool might be able to yield the strong commons that I appreciate in Factor. Best, John. P.S.

Re: [Factor-talk] Comments on 'Your First Program
Hi Mike, Great input, thanks! A few questions - 'Writing some logic in your first program' After it says 'Place this definition at the end of your source file.' I suggest adding: 'Note that a space is significant in Factor.' What exactly are you trying to communicate with this -- that we require spaces to tokenize? Multiple spaces are treated the same as a single space, indentation doesn't matter (although tabs are disallowed as blank characters). Where it says: 'Enter dup in the listener's input area, and press C+h.' This didn't work, so I wondered what C+h actually meant. I have never seen Ctrl and Alt shortened to C and A before. It turned out that I had to highlight dup, so I suggest replace the sentence by: 'Enter dup in the listener's input area, highlight it, then press Ctrl+h.' You can also position your cursor on or immediately after the word you want to Ctrl+h.

But, I got gvn-tests.factor working without needing any changes to the GVN pass itself, so I reckon the math.vectors.simd tests will still fail. Hopefully one of you knows more about how to go around debugging those tests than I do? (If you can reproduce, anyway.) As for the code itself, I started by copying over basis/compiler/cfg/value-numbering/ to extra/compiler/cfg/gvn/ and changing it there. It was easier during development to not touch an existing compiler pass, lest the whole listener break. The diff between the gvn value-numbering stuff is actually pretty small. But since they're different files, it might be a bit of a pain to figure some stuff out (to make sure you like it or whatever). I've found myself doing a lot of `git diff --no-index` and `git merge-file basis/stuff /dev/null/ extra/stuff` to resolve discrepancies. Pretty sure I took care of the few changes made to the value-numbering vocab while I was working on gvn: https://github.com/ajvondrak/factor/commit/beff2088132d992c983ddebe5860183f01bc8b5e Otherwise, it should be a drop-in replacement of value-numbering: just change references to compiler.cfg.value-numbering into compiler.cfg.gvn in math.simd.vectors.intrinsics and compiler.cfg.optimizer. Extra things I can think of: - I needed to make a minor change to compiler.cfg.copy-prop due to the GVN changes, so that'll be in there. - The reason I wrote the graphviz vocab was to facilitate the fun stuff in https://github.com/ajvondrak/factor/blob/gvn/extra/compiler/cfg/graphviz and https://github.com/ajvondrak/factor/tree/gvn/extra/compiler/cfg/gvn/testing so I could include CFG diagrams in my thesis. - Just last night, I tried out a fresh 0.95 download's `load-all test-all` (in ./factor -run=listener) on my x86_64, up-to-date Arch install (same hardware as before). Still crashed, but instead of getting out of memory I got a memory protection fault from the gc. I hope to be improving the GVN pass some once I can get these errors figured out. :-/ I notice there's been an issue opened about load-all test-all running out of memory (https://github.com/slavapestov/factor/issues/633); don't know if that's in response to what I brought up or not. So, I guess I kind of just went text dump mode there, but let me know if you have any questions or if there's anything I can do to help.

Re: [Factor-talk] glitch in smtp/mail/ui, redux
Hi cw,
Thanks for the report! I'm glad you got it working, sorry that it was a
bit bugged (we changed prepend to make the type of the first argument and
this apparently broke). I just committed a fix for it, making
plain-auth-string return a string, instead of a byte-array.
Let me know if you run into any other problems!
Best,
John.

Greetings, Factoristas - (Slimmed-down revision of earlier bloated post)
Found a small bug in smtp.factor, and suggest a fix.
I ran into a glitch trying out the mail-ui vocab, from the recent Re:
Factor blog (mrjbq7-re-factor-ac166fe).
I did note the necessity of setting up SMTP to use gmail, though I
couldn't get that to happen via
.factor-boot-rc. Instead, I just added the set-up code to mail-ui.factor,
to be called from the
top-level word, open-compose-window:
--
USING: smtp namespaces io.sockets ;
: setup-smtp ( -- )
cwalsto...@gmail.com mail-password plain-auth smtp-auth set-global
smtp.gmail.com 587 inet smtp-server set-global
t smtp-tls? set-global ;
---
~So far, so good. The 'compose' window comes up and accepts text just
fine.
But clicking the 'send' button throws this error:
Generic word aux does not define a method for the byte-array class.
Dispatching on object: B{ 65 85 84 72 32 80 76 65 73 78 32 65 71 78 51
~36 more~ }
~Error occurs where the slot accessor aux fails on the base64 auth
byte-array, looking for
a string instead. So, I made a small change to the send-auth method of
plain-auth in smtp.factor
to output a string rather than a byte-array and succeeded in a soliloquy
with my gmail account:
---
M: plain-auth send-auth
[ username ] [ password ] bi
plain-auth-string
!AUTH PLAIN prepend command get-ok ---*CHANGED TO*:
* AUTH PLAIN prepend-as* command get-ok ;

~Now I've got mail!

Re: [Factor-talk] Quick Question For Chris Double
Given these caveats, here’s an introductory list of topics (in no particular order) I would propose to cover. Any feedback on suitability and valuable additions/deletions would be greatly appreciated: Defining by combination in Factor and effective use of Higher Order Functions Partial parameterization and Currying Effective use of Pattern matching Effective alternation (if/else, switch, etc.) Iteration in Factor Induction and Recursion Lists, Tuples, Records and Arrays in Factor Effective use of named stack parameters and local variables Overloading – effective use of Factor’s Generics List and array comprehensions and lazy sequences in Factor Creating and using effective algebraic data structures ** I think this would be a nice structure, there are probably bits and pieces of these sections in the Factor documentation (for example, the Factor cookbook http://docs.factorcode.org/content/article-cookbook.html or The languagehttp://docs.factorcode.org/content/article-handbook-language-reference.html articles).

Re: [Factor-talk] Namespaces in Factor
Typically, you would need to specify which word you mean: Given: IN: vocab-a : foo ( -- x ) 12 ; IN: vocab-b : foo ( -- x ) 14 ; IN: vocab-c : bar ( -- x ) foo ; This would happen: IN: scratchpad USE: vocab-c Loading resource:work/vocab-c/vocab-c.factor Loading resource:work/vocab-a/vocab-a.factor Loading resource:work/vocab-b/vocab-b.factor 1: USE: vocab-c ^ resource:work/vocab-c/vocab-c.factor 6: : bar ( -- x ) foo ; ^ More than one vocabulary defines a word named “foo” The following restarts are available: :1 Use the vocab-a vocabulary :2 Use the vocab-b vocabulary :3 Load resource:work/vocab-c/vocab-c.factor again You can fix this by adding something like: FROM: vocab-a = foo ; Or using QUALIFIED: or QUALIFIED-WITH: to fix the ambiguity.

Factor source code is loaded from files, which can be edited in VI or your favorite editor. And linked via the edit word so you can open code into your editor.

Re: [Factor-talk] Button stack effect problem
If you use global values, this should work: SYMBOL: a 1 a set-global Press [ drop a get-global ... ] border-button gadget. The problem with set and get, is that the 'set' is using the namespace of the listener which may (likely not) be the namespace of the quotation being executed by the quotation. Namespaces are hierarchical, so you want to make sure that the value is set in either the current scope or one of the outer scopes to be accessible. Does that make sense? By the way, there are several ways to get your code to work, through currying as was mentioned previously, namespaces like you are trying now, or even subclassing a button and storing your value in a slot, e.g: TUPLE: a-button button a ; : a-button ( label quot -- button ) a-button new-button border-button-theme ; Press [ a ... ] a-button 1 a gadget.

Although, what I would like to do is to set the value of the symbol a from inside the quotation. How can I do that? 2012/12/17 Samuel Proulx proulxsam...@gmail.com I see! Thank you for your help and your explanations! 2012/12/17 Jon Harper jon.harpe...@gmail.com The quotation you pass to the border-button constructor gets called by the system when the button is pressed. At this time, the stack has nothing to do with the stack shown in the listener. So you don't have the reference to the label. To have a reference to the label when the quotation is called, you should make a closure. This can be done with curry (or, in this case, the more appropriate with): Test label dup gadget. Press [ drop Worked text drop ] with border-button gadget. Other ways of creating closures are fried quotations ( http://docs.factorcode.org/content/article-fry.html) or local variables (http://docs.factorcode.org/content/article-locals.html) Cheers, Jon On Mon, Dec 17, 2012 at 10:48 PM, Samuel Proulx proulxsam...@gmail.comwrote: Hi, Yet another problem...
