With MkIV you can get a xml version of document with \setupbackend[export=yes].


But that XML is not ePUB's XML, I assume.


no, but one can of course convert one kind of xml into another

for epub one has to provice css etc anyway (and epub is not much more

going the other way around, processing an epub file also demands some

This would also be useful to me. In my experience, the unpleasant part of 
generating ePub is making correctly formatted manifests and putting them in the 
right places inside the right kinds of zip files. If ConTeXt could do this for 
me, it would certainly make life easier. On the other hand, it may not be 
appropriate to bother because there are other tools that will convert HTML to 
ePub for you and make the manifests (Calibre, for example). 

I consider CSS intractable so that's not something I would worry about ConTeXt 
generating for me, if it were on the table.

 going the other way around, processing an epub file also demands some 
 handywork as the source code is not by definition well structured


ePub is definitely structured. I would say too structured, since it makes you 
provide both a ToC manifest and a navigation manifest that necessarily must 
include almost identical information ;) Of course, depending on a simplified 
browser for your document viewing and having lots of secret failover modes to 
handle poorly formatted documents makes the structure less meaningful than it 
ought to be.

You are free to break your document into as many HTML chunks as you wish, but 
you are limited to fairly prosaic HTML and CSS. I'm of the impression the HTML 
documents generally map onto chapters so as not to distress the hardware's 
memory constraints too much.

Overall, ePub and Kindle's format strike me as too much and too little 
respectively. I should be able to change the font and the formatting, but I 
definitely consider HTML + CSS is too much complexity.

[NTG-context] drop-cap quote character

2011-02-17 Thread Daniel Lyons
Ideally, \DropCap would notice a piece of leading punctuation and drop it as 
well. Instead, it seems to look at the punctuation and give up.

Example:


\def\Drop {\DroppedCaps
  {} {Serif} {4\baselineskip} {2pt} {2\baselineskip} {3}}

\starttext

{\Drop A} \input knuth

\page

{\Drop “A} \input knuth
\page

\stoptext

Advice?

Thanks again,

i have a style somewhere that typesets an epub document (directly) but

 Hi all,
 
 I noticed that although mtxrun preloads some of the context libs
 that doesn’t cover everything available during an ordinary mkiv
 run.  What would be the canonical way to load additional libs
 like “luat-ini”c. on demand? “environment.loadluafile()”? Can
 this be configured globally? Is it wise to mess with “own.libs”
 in mtxrun?
 
 Example: This snippet checks the global env for some tables.
 “mtxrun --script” doesn’t find any while some of them are there
 when processed as cld.
 
 something
 
 dofile(resolvers.findfile(yourfile.lua))
 
 but keep in mind that most of the mkiv code depends on other code
 and often they depend on functionality that is only available when
 we're in luatex mode and not in texlua mode

In this case there were two deps. I extracted the order in which
the libs are loaded by context and put it on the wiki. This isn’t a
*real* dependency tree but still it can be of help when
troubleshooting similar issues. 
http://wiki.contextgarden.net/Running_Lua_Code_Externally#Standard_library_loading_order

Thanks for the pointer, Philipp

[NTG-context] Format of included PNG images

2011-02-17 Thread Marco
Hi,

I read that most programs convert PNG images to JPEG images while creating PDF
files.

Is this also true for ConTeXt/LuaTeX? What happens when PNG images are
included?


Regards
Marco

The only time this will (or should) happen w/ any program is when creating a 
.pdf w/ a specification which sets pixel images to use compression JPEG 
compression.

I don't believe there are any pdf-creating tex implementations which will 
reprocess images in this fashion (normally they're simply encapsulated in the 
file as is).

Re: [NTG-context] EPUB workflow from ConTeXt source?

2011-02-17 Thread Mica Semrick
Have you considered authoring in something besides context? Say TEI XML or
Docbook, or even markdown (if possible)? If markdown is suitable, then you
can end up with both epub and context at the end. Or if using TEI or
docbook, you can write a map file (something I have been trying to do) and
typeset the xml file directly with context. I'm always happier knowing that
I can get as many different output types from a single source as possible.

BR,
Mica

  I'd like to keep working in one format so I was wondering if there is
 a
  ConTeXt based workflow/setup that can produce EPUB (next to normal
 PDF)?
 
  With MkIV you can get a xml version of document with
 \setupbackend[export=yes].
 
  But that XML is not ePUB's XML, I assume.
 
  no, but one can of course convert one kind of xml into another
 
  for epub one has to provice css etc anyway (and epub is not much more
 than packaged html + css)

 This would also be useful to me. In my experience, the unpleasant part of
 generating ePub is making correctly formatted manifests and putting them in
 the right places inside the right kinds of zip files. If ConTeXt could do
 this for me, it would certainly make life easier. On the other hand, it may
 not be appropriate to bother because there are other tools that will convert
 HTML to ePub for you and make the manifests (Calibre, for example).

 I consider CSS intractable so that's not something I would worry about
 ConTeXt generating for me, if it were on the table.

  going the other way around, processing an epub file also demands some
 handywork as the source code is not by definition well structured


 ePub is definitely structured. I would say too structured, since it makes
 you provide both a ToC manifest and a navigation manifest that necessarily
 must include almost identical information ;) Of course, depending on a
 simplified browser for your document viewing and having lots of secret
 failover modes to handle poorly formatted documents makes the structure less
 meaningful than it ought to be.

 You are free to break your document into as many HTML chunks as you wish,
 but you are limited to fairly prosaic HTML and CSS. I'm of the impression
 the HTML documents generally map onto chapters so as not to distress the
 hardware's memory constraints too much.

 Overall, ePub and Kindle's format strike me as too much and too little
 respectively. I should be able to change the font and the formatting, but I
 definitely consider HTML + CSS is too much complexity.
