Ok, sliders, rulers, analog clocks... anything else?

Aside from the syntax, this could be done as a user-defined datatype. 
Or it could be done as an API.

Anywhere you want to count with varying base on multiple numbers 
and act on it. I've run into this numerous times.
BrianH, are there docs anywhere on user defined datatypes yet? Limitations?
BrianH

Just discussions, but I know what the limitations are.

Henrik, I'll have to think more on it.

Steeve, where was your disk-block scheme source?

thanks. maybe it's better to implement it as a scheme anyway.

I'm confused on your proposal as wel Henrik. A concrete example would 
really help, since it's a complex concept.
Henrik

I think I'll wait. I've discovered some problems with the idea, which 
makes it less useful than I thought it would be.

Eh Ammon ! how do you manage selection over several text gobs ?

I'm trying to do it currently, but i'm not sure to have the best 
design
Ammon

I haven't gotten that far yet.  I recently had to rewrite my parser 
from the ground up, mostly due to the fact that NOT isn't implemented 
yet and I want to be able to handle unicode without too much trouble. 
 I think I'm going to have to handle a lot events like text selection 
by passing them through the text faces to the main scrollable area 
and let it handle them.  I expect I'll be rewriting the highlighting 
from the ground up.

i'm rewritting completly the key handler with my own cursor (a gob). 
I don't like the default handler
Ammon
25-Mar-2009
[12293]
I like the design of the default handler.  =D  I'll need to modify 
or extend it before I'm through though.
Steeve

[12294]
too much ovverrides have to be done, redoing it from the scratch 
is simpler
Ammon
25-Mar-2009
[12295]
You know that you can get the source from DevBase, right?
Steeve

my cursor is gob i'm moving from gobs to another gobs
i have the sources
Ammon
25-Mar-2009
[12298]
Yup, I'll be doing that as well.
Steeve
25-Mar-2009
[12299]
in the default design, the cursor is not a gob
Ammon
25-Mar-2009
[12300]
well, the handling of text editing is very powerful.  I will definitely 
be using the same design just extending it a bit.
Steeve
25-Mar-2009
[12301x2]
i don't like it so much ;-)
but perhaps i'm wrong
Ammon

It's a simple state machine.  It's taken me a long time to grok what 
can be done with such a system but now they are starting to dominate 
my code.
Steeve
25-Mar-2009
[12304]
A state machine ? What a big word. It's just a serie of switch commands 
:-)
Ammon
25-Mar-2009
[12305]
Instead of having to add a lot of refinements and refinement handling 
to related functions you can just put them together into an object 
and as each of the functions are called they are setting values that 
are local to the collection of functions and each of those values 
modify the behavior as if you were using refinements and passing 
in more values.  It's kind of an inference engine.
Steeve
25-Mar-2009
[12306]
Again, what a big word. I do that too to have a more readable, and 
compact code. 

I don't like to pass thousand of parameters. But nothing is related 
to a state machine to my mind
Ammon
25-Mar-2009
[12307x3]
You may be right.  I may be misinterpreting the meaning of state 
machine...
I'm seeing some strange behavior with Parse...

ws: charset rejoin [space tab newline]

parse "   This is a test!" [s: some ws e: (probe copy/part s e) to 
end]
; == false

parse/all "  This is a test!" [s: some ws e: (probe copy/part s e) 
to end]
; "  "
; == true

I shouldn't need /all when I provide a rule block should I?
In truth it doesn't always fail but I'm not sure what causes it to 
change it's behavior.
Ammon
26-Mar-2009
[12310]
Heh.  Or rather I don't know why SOME was ever working but I saw 
it work once.


parse "  ^- this is a test!" [s: any ws e: (probe copy/part s e) 
to end]

ANY appears to work all the time though.  Strange.
Steeve

charset is bugous in R3 currently
Ammon
26-Mar-2009
[12312]
So this is a problem with Charset not Parse?
Steeve
26-Mar-2009
[12313x3]
I made my own function.
charset: func [str /local bitset][
	bitset: make bitset! 256
	foreach char str [append bitset char]
]
to be right, is used this to make complement of charsets
you made a mistake bout the understanding of /all refinement, see 
help
Ammon
26-Mar-2009
[12316]
You're not making much sense.
Steeve
26-Mar-2009
[12317x3]
Sorry, i mean, forget my charset function. your problem is the missunderstanfing 
og /all refinement
/all -- Parses all chars including spaces.
if not, spaces are skiped.
spaces are : space, newline, tab
Ammon
26-Mar-2009
[12320x2]
Yeah, I read that part.  For some reason I thought parse didn't skip 
whitespace if you provide a block but this clearly shows otherwise...


>> parse " a b c ddd " [ "a" (print 'a) "b" (print 'b) "c" (print 
'c) some "d" (print 'd)]
a
b
c
d
== true
But why does ANY work without /all while SOME doesn't???
Steeve
26-Mar-2009
[12322x2]
because any is an optionnal rule not some
basics
Ammon
26-Mar-2009
[12324]
That doesn't make sense to me still.  If the parser is skipping whitespace 
unless you use /all then any should fail the same way that some does.
Steeve
26-Mar-2009
[12325]
No, Optionnal means that if ANY fails , the parsing process continue 
with the next rules
Ammon
26-Mar-2009
[12326]
Ah, but ANY didn't fail.  The paren was evaluated which means that 
ANY succeeded.
Steeve
