Re: [Factor-talk] 4DStroll - a 4D visualisation tool
Hi, I updated a bit the code since last post. Source can be found on https://github.com/Bigot/factor/tree/4DStroll/extra/4DStroll It's now possible to : - group/ungroup solids. - choose solids to add (simple way) - modify name and color of objects (basic way) 4DStroll begin to be usable to build 4D structures with basic bricks. The are still some flickering on some computers and I never acheived to include all 4 views in a single window. It's sad but I think I don't really understand how opengl works. Any help would be welcome. Thanks Jeff Le 9 janv. 2014 à 20:04, John Benediktsson a écrit : Hi Jeff, Very cool, is there a demo somewhere I can run to see how it works?

Hi
From time to time there is a question on the mailing list about a
paper doc for latex.
As exercise to discover streams, I made a first attempt to write a
latex output for doc. It's a modified version of help.html vocab.
You can found it in the latex directory on
git://github.com/Bigot/work-bgt.git
Useful words are in latex.help :
- cookbooklatex ( -- ) to generate a cookbook tex file
- word-helplatex ( word -- )
- vocablatex
I also tried a generate-latex-doc word but my factor gets very slow
after having generated 17500 files. My idea was to use \input
{subfile} in a main latex document to concat needed pages.
I still have several difficulties
- I don't know how to handle stream-nl in order to avoid unwanted
line break after commands
- in each help page there are two title-style elements, a block
included in a span. I have no nice solution to keep only one, I
decided to add a $tex-plain-span symbol in stylesheet.
- I don't know the best way to add color to factor code.
- Is it better to use LGRIND package ? is anyone already used it ?
- or is it better to write a factor word to parse code ?
For the next step I will add refs in order to build an index and
allow hypertext navigation in pdf file.
I rarely use latex so I'm interested by any feedback and advice.
I hope it will be useful.

[Factor-talk] deep-cleave-quots
Hi,
When I try to do something in Factor:
1. I look in libraries if a word do what I want (not always simple,
and sometimes really hard)
2. I try to do it by myself if it is easy
3. I look at examples in extra vocabs and try to understand what is
done (a great hand parsing job !)
When I began 4DNav I defined my own camera movements. I then
discovered opengl.camera and I refactored my code to use this vocab
(Self always looks magical for me but it woks).
When turtle disappeared due to delegation incompatibility I tried to
rewrite it. The only solution I found was to merge into a single file
turtle pos and ori. Not very nice but that works.
Make-matrix was easy to understand and do the job well.
Of course your new Rz code is simpler to read and reusable
everywhere. It is what I always looked for.
But I am not sure that the gap between:
: make-matrix ( quot width -- matrix ) r { } make r group ; inline
(oups sorry, [ { } make ] dip group )
and
:: [deep-cleave-quots] ( SEQ -- quot )
[let | QUOTS [ SEQ [ quotation? ] deep-
filter ]
RECIPE [ SEQ [ dup quotation? [ drop , ] [ ] if ] deep-
map] |
[ QUOTS cleave RECIPE bake ] ] ;
MACRO: deep-cleave-quots ( seq -- quot ) [deep-cleave-quots] ;
is easy to cross for a newbie. Slava's solution is more readable for
me, but the most difficult point is to discover that words like deep-
map and deep-filter exist.
By the way I also used make-matrix for my 4D rotations, I will
rewrite my code with deep-cleave-quots. Also with this new word I
would now be able to implement a word for a rotation in a N
dimensional space in order to factor Rx Ry Rz, 4D-Rxy, 4D-Ryw...
thanks for your precious advices

[Factor-talk] ID with postgres DB
Hi
I want to use factor database library wih postgres but I have a
little problem with primary key names.
It looks like primary key must be id.
When create-table is called, create-function-sql uses table name
and suffix it with _id_seq to give a name to currval
select currval('' 0% 0%
_id_seq'')
If primary key is not id but tablename_id, postgres creates
tablename_tablename_id_seq as curval.
create-table fails because it looks for a tablename_id_seq curval
which does not exist.
Would it be possible to modify create-function-sql in db.postgres
to handle pk name other than id ?
thanks

Re: [Factor-talk] What is a good definition ?
Hi,
Eric nicely gave me his solution :
DEFER: combinations
: (combinations) [ 1 tail ] dip combinations ;
: prefix-each [ prefix ] curry map ;
: combinations ( seq n -- seqs )
{
{ [ dup 0 = ] [ 2drop { { } } ] }
{ [ over empty? ] [ 2drop { } ] }
{ [ t ] [
[ [ 1- (combinations) ] [ drop first ] 2bi prefix-each ]
[ (combinations) ] 2bi append
] }
} cond ;
It looks nice :
- only three conditions,
- very few shuffle words
- a good name
- prefix-each makes sens
OK lets try
[ 20 20 array 20 [ among ] with each ] time
= end sequence error
I missed something (Eric didn't !)
I add a condition to my def that becomes
: columnize ( seq -- seq )
[ 1array ] map
; inline
: among ( seq n -- seqs )
2dup swap length
{
{ [ over 1 = ] [ 3drop columnize ] }
{ [ over 0 = ] [ 2drop 2drop { } ] }
{ [ 2dup ] [ 2drop [ 1 cut ] dip
[ 1- among [ append ] with map ]
[ among append ] 2bi
] }
{ [ 2dup = ] [ 3drop 1array ] }
{ [ 2dup ] [ 2drop 2drop { } ] }
} cond
;
so again
[ 20 20 array 20 [ among ] with each ] time
= 8953 ms run / 4142 ms GC time
and after
[ 20 20 array 20 [ combinations ] with each ] time
= 20500 ms run / 6359 ms GC time
I tried several times to be sure !
for 10 10 array 10 results are equals to 16 ms but for large
number Eric's nice word is twice slower than mine.
WHY ?
Are there rules to optimise a word ?
On what point must we focus to build efficient code ?
