The original report.

OTOH it may not be related.

ok, thanks. I'll write up the report.

thanks

btw. are there any margins to adjust? could it be that?

i don't think so, the margin and origin are too low to explain the 
gap

i tried with a margin of 2x2 and an origin of 2x2, but what is missing 
is 30-50 pixels

then the error is not constant. I experienced an error of about 2-4 
pixels here.

try with a big font

hmmmm.... seems you're right. By removing origin and margin, i got 
the correct size.
Arghhhh, it was not a bug actually

Forget the bug Henrik, thanks for your help.

A good evolution would have size-text taking in account origin and 
margin

no problem and yes, that could be a good idea.

Heh, Steeve.  You are working on a rich text editor too, huh? 


Are you using a single face, gob and draw, faces and gobs, just gobs 
or something entirely different?

1/ I mix several gobs of all types (effect draw text color). Basicaly, 
drawings can be mixed with texts.

2/ only gobs which are modified are reconstructed, it should be fast 
to insert modify text.

3/ The structure of gobs is build using an external  grammar (with 
parse), depending of the source file type. The parser convert the 
source text into a DOM structure,  which is converted into a gobs 
structure further usings a style grammar (external too).

4/ It will be a verstatil richtext editor. By changing of external 
grammars (basically a set of parse rules), we change the rendering.

5/ The grammar for a specific markup langage will be tiny. Currently, 
the grammar of makedoc2 is less than 2 Kb.

6/ In theory, easy conversion between different makup language could 
be done by the engine (makedoc <-> postscript <-> pdf ...)

7/ After makedoc2 rules will be ok, I'll build a grammar for rebol 
sources of course.

Sounds like a pretty awesome engine.  Can't wait to play with it. 
=D

Is there a way to complement bitsets in R3 ?
I liked the NOT proposal in parse, but it's not done yet.

Theoretically you could build a complement set in R2 and just copy 
the bitset to your R3 script but I think that will cause you some 
problems with unicode, which, as I understand it, is why complement 
has been removed in R3.

Currently, i do this, but...

no-chars: make bitset! 256
foreach c "^/^-" [append no-chars c]
no-chars: complement no-chars

geez...
drop and off don't work in rich-text

known bug

Fuck !

sorry

:-) I'm not sure if there is a workaround.

Generally we'll have to talk to Cyphre one day. His bug list is getting 
quite large.

workaround...

bye bye my rich-text engine

another one project fail, my speciality....

Drop and Off?  What are you talking about?

used to discard previous commands in rich-text blocks (like bold, 
underline, italic)

Ah...  I'm sure they'll fix that eventually...

eventually, mwahahahaha

I'm building my rich text editor on the gob/face level so that won't 
be bothering me. Getting this parser right is proving to be tricky 
though!

eh ? i don't understand why you are not impacted...

when i talk about rich-text, i mean gob/text, so you are impacted

me too, i create my own gobs

i don't use those Carl's style

I'm not impacted because each style change creates a separate face.

I'm not using Draw directly.

and ? 
How do you handle imbricated styles in the same line of text ?
Like:

 gob/text: [ bold "this is bold" italic "this is it talic and bold" 
 off "this is bold" ]

Especially if the line is wrapped

don'

Hehe, I'm not writing that kind of Rich Text editor...  It's really 
just a syntax highlighter so all of the formatting is implicit.

if you construct linked gobs for the same line of text (one gob = 
one style), i say good luck to manage wrapped lines.

hum ok, it's more simple

you just change colors

Managing wrapped lines isn't a concern at the moment.   What I will 
be able to do with the structure I've chosen far outweighs the extra 
cost dealing with wrapped lines if I ever decide to add that functionality.

No, not just colors.  You have full font control, bold, italic, etc

i'm fucked, my current development is about editing makedoc documents, 
i can't bypass this request

i need wrapped paragraphs

rich-text at gob level must work

yeah, for what you are doing Drop and Off definitely have to work!
