It's worse than pre-TeX printed books. Which makes me wonder: is anyone in the world addressing this? Are there people in the TeX community involved in the standardization processes (say, Epub3, but also the various W3C specifications), who could push forward ideas from TeX, like minimum requirements for the algorithms that rendering engines should use?

[NTG-context] Hooking \stoptext
Hello,
I'd need to to hook \stoptext by Lua - I'd need to write something right before
the end of the text.
See the simple example:
t-Hook.mkiv
\startluacode
local stoptext_p = context.stoptext
context.stoptext = function(...)
context("END")
stoptext_p(...)
end
\stopluacode
\starttext
\input knuth
\stoptext % To be hooked by Lua
This code should write "END" right before the end of the document, but it
doesn't.
How to achieve that?
- I'd rather Lua to TeX do the job as I need Lua to do more complicated things
(the example above is very simplified).
TIA.
Best regards,
Lukas

Re: [NTG-context] Hooking \stoptext
... OK, your solution works -
- But I'd need one which doesn't force user to hook manually; i.e. without:
\let\Oldstoptext\stoptext
\def\stoptext{%
\startluacode
context("END")
\stopluacode
\Oldstoptext
}
Hooking should be performed in a Lua function and should be "invisible" to the
user.
More complicated example:
t-Hook4.mkiv
\startluacode
function foo()
local stoptext_p = context.stoptext
context.stoptext = function(...)
context("END")
stoptext_p(...)
end
end
\stopluacode
\starttext
\input knuth
\ctxlua{foo()} % This should cause "END" to appear at the end of the document
\stoptext
In this case, "foo()" is a function which does the hooking; and "foo()" may be placed in
another file or Lua toolbox, so user is to call Lua's "require 'my-Lua-toolbox-with-foo' foo()".
So user is not forced to know how the function works; once he uses it, the text
"END" will appear at the end of the document.
- And this doesn't happen to me; and my goal is to make it work.

context.stoptext() just calls “\stoptext”, not the other way
round. Btw CLD are implemented as metatable so afaik you would
have to redefine the “__index” attribute.

You can also write your own stop/stop-commands for the document like
\def\startmydocument
{\starttext}
\def\stopmydocument

\stoptext}
and use them instead of \starttext and \stoptext.

Re: [NTG-context] Style file for iPad?
A while ago I grabbed some mathematics book samples for the Kindle. These were books produced by well-known publishing companies, retailing for considerable sums (even in the electronic versions), and in all of them the mathematics typesetting was atrocious. I think that in most (all?) ebook formats, a formula is included as an image, which means that it automatically resizes. This means that formulas may be of all different sized fonts, which gives the result a very scrappy look. At least PDF - even if not designed for ebook reading - provides decent layout. The problem is not just mathematics. I have some ebooks about poetry, and in them the included poems (as set off from the surrounding text), seem to be typeset almost randomly, with regard to layout, font size and spacing. And these are commercial ebooks, for which I paid real Earth dollars! -Alasdair On Thu, Mar 8, 2012 at 3:30 AM, William Adams wrote: > On Mar 7, 2012, at 3:34 AM, Nicola wrote: > > > It's worse than pre-TeX printed books.
