[NTG-context] [luatex-fonts] non-ascii filenames in font cache

2013-04-28 Thread Philipp Gesang
Hi Hans,

the font cache currently drops non-ascii bytes when creating file
names by means of containers.cleanname(). Dohyun Kim sent a fix
for data-con.lua (see below). My own test with the unicode
library leads to some odd results.

Also I noticed that as a pattern, [^%w%d] is a bit redundant
since %d is a subset of %w in both string and unicode.utf8.

Regards
Philipp



#!/usr/bin/env texlua
local non_ascii_names = {
  [[华文仿宋.ttf]], [[华文细黑.ttf]], [[华文黑体.ttf]],
}

--- [a]: current data-con
--- [b]: include non-ascii (proposed by Dohyun Kim)
--- [c]: with selene unicode

for i = 1, #non_ascii_names do
  local name = non_ascii_names[i]
  print
  print([a], name, string.gsub(string.lower(name), 
[^%w%d]+,-))
  print([b], name, string.gsub(string.lower(name), 
[^%w%d\128-\255]+,-))
  print([c], name, unicode.utf8.gsub(unicode.utf8.lower(name), 
[^%w%d]+,-))
end

strange that it wasn't noticed before as it's rather old code

function containers.cleanname(name)
return (gsub(lower(name),[^%w\128-\255]+,-))
end

is good enough i guess

[NTG-context] codefolding with Kate or Kwrite

2013-04-28 Thread Jan Heinen

Hello,

is someone else using the editors kate and kwrite?

Code-highlighting is working.

What I need ist code-folding for ConTeXt. Is this possible?
I have huge makros with lots of  \doif ... \else ... \fi
and it is hard to surf through the code.

What else would be nice: auto-indentation ... marking all 
the code and let kwrite/kate do the job to indent.

Re: [NTG-context] Supressing a heading from the table of contents

2013-04-28 Thread lance.c.lar...@gmail.com
Thanks Wolfgang. This is just what I needed. This will solve the issue. Much 
appreciated.

 

-Lance

 


 Can anyone tell me how to suppress individual numbered 
 chapter/section/subsection/etc. from the table of contents?

The only reliable method at the moment is to create a clone of \chapter.

 Also how do you set the last heading level included in the table of contents. 
 I think I came across this, but am having trouble finding it again.
  

You can use \placelist where list only the headings which should appear, e.g.

  \placelist[chapter,section]

or you change the list for the \completecontent.

  \setupcombinedlist[content][list={chapter,section}]

[NTG-context] space before and after headlines

- before the headline there should be a big space
- after it a small space
- when  the headline is at the beginning of the page there 
shouls be no space before the headline.

\starttext

{bf Headline 1}
\blank

On 2013–04–28 Keith J. Schultz wrote:

The typescripts themselves are full of spaces and new lines. And you
really want those spaces for readability. TeX usually squashes
multiple spaces into one, but spaces still matter in many
circumstances, e.g. within an \hbox.

 If the code that does load the file/s produced spaces for
 debugging purposes that is fine, but should not they actually
 going somewhere else?

There's no code that produces spaces. The spaces are in the
typescript file.

 Personally, I find it a bug if loading fonts or other files
 produces extraneous  characters!

This is usually not a problem, since typescripts are loaded in the
setup area. Even when loaded within the text area the spaces don't
cause problems. Loading an entire file within a box, like I did in
the example, is an unusual edge-case and there's a simple
workaround, see Wolfgangs answer.

Except if there's an easy fix for that, I'm personally fine knowing
where the spaces are coming from and how to prevent them, which I do
now.

normally it only matters in hmode

when you \usetypescriptfile[iwona] outside the macro the definitions get 
preloaded in memory ; in fact, each typescript eventually gets cached


typescripts are loaded under a newline restricted regime but that 
doesn't always prevent spaces creeping in (like those before comments)


\definetextext
  [foo]
  [#1]#2{\switchtobodyfont[#1]\removeunwantedspaces#2}

and moving all to lua is no option now (although ... in 
antykwapoltawskiego.lfg one can see how such a thing can be done)

Hi Marco, All,

agreed you can avoid the spaces by putting the usetypescript in the preamble,
but should not the loading of a typescript not bleed any spaces!

Keith.

 The typescripts themselves are full of spaces and new lines. And you
 really want those spaces for readability. TeX usually squashes
 multiple spaces into one, but spaces still matter in many
 circumstances, e.g. within an \hbox.
 
 If the code that does load the file/s produced spaces for
 debugging purposes that is fine, but should not they actually
 going somewhere else?
 
 There's no code that produces spaces. The spaces are in the
 typescript file.
 
 Personally, I find it a bug if loading fonts or other files
 produces extraneous  characters!
 
 This is usually not a problem, since typescripts are loaded in the
 setup area. Even when loaded within the text area the spaces don't
 cause problems. Loading an entire file within a box, like I did in
 the example, is an unusual edge-case and there's a simple
 workaround, see Wolfgangs answer.
 
 Except if there's an easy fix for that, I'm personally fine knowing
 where the spaces are coming from and how to prevent them, which I do
 now.

it's not the typescript that has the space but the file ... a typescript 
file can have more than typescripts like definitions, documentation, etc.


In the past, one *always* had to load a typescript file explicitly but 
at some point - out of convenience - the \setupbodyfont mechanism has 
been extended to automatically load a typescriptfile with the same name 
as the requested bodyfont. So, it's the price paid for convenience. And, 
in most cases a bodyfont is not initialized in a \hbox.

Keith.
