[NTG-context] \completepublications in component creates wrong hyperlinks

2013-08-05 Thread Marco Patzer

Hi,

if a \completepublications call is used in a component, the
hyperlink, which is supposed to link to the bibliography, instead
links to a (probably non-existing) pdf file named after the
component.

\startbuffer [sample]
  @BOOK{Eijkhout1991,
title = {\TeX\ by Topic. A \TeX nician's Reference},
publisher = {Addison-Wesley},
year  = {1991},
author= {Victor Eijkhout},
address   = {London},
keywords  = {general},
  }
\stopbuffer
\savebuffer [list=sample, file=bibliography.bib, prefix=no]

\startbuffer [component]
  \startcomponent *
\completepublications [criterium=text]
  \stopcomponent
\stopbuffer
\savebuffer [list=component, file=bib-component.tex, prefix=no]

\setupinteraction [state=start]
\setupbibtex [database=bibliography]
\starttext
  Some text. \cite [Eijkhout1991]

  %% creates a hyperlink to bib-component.pdf
  \component bib-component

  %% this one works
  %% \completepublications [criterium=text]
\stoptext

Re: [NTG-context] \externalfigure doesn't find mps file in subdirectory

Yep, that’s a problem all right. A bug, even: when you put `simple.1`
in the same directory as the `.tex` file, it is correctly identified
as MetaPost; when you put the exact same file in a subdirectory like
`./fig`, you get the problem you describe. No clue why.

Until Hans fixes this, you can force ConTeXt to treat a file as
MetaPost, JPEG, etc. by passing the `method=` paramater to
`\externalfigure`. For MetaPost, write `method=mps`; I don’t know why
the MetaPost code is not `mp`. (Perhaps that could be made a synonym?)

Complete example below. I hope this workaround helps? Good luck with your work!


you can test with this (line 767 in grph-inc):

askedformat = format -- new per 2013-08-05
elseif trace_figures then
report_inclusion("unknown format %a",askedformat)
end



Cheers,

Hello, good people--

I've encountered what appears to be a bug in either the TeX->Lua
interface or the documentation thereof (I have the latest stable
ConTeXt standalone from contextgarden.net).

I'm trying to create a macro that will insert different text depending
on whether one of the arguments is empty or not. My initial test
implementation (following the wiki section entitled "Passing arguments
and buffers: ConTeXt commands that hook into Lua") looked like this:

\startluacode
 userdata = userdata or {}

 function userdata.empty_or_not(str)
 if str == "" or str == nil then
 context("{\\sc Empty}")
 else
 context(str)
 end
 end
\stopluacode

\def\emptyOrNot#1{%

}

\starttext

 \emptyOrNot{Amazing Text!}

 \emptyOrNot{}

\stoptext

This did not work. I determined that even when I passed a non-empty
string, the Lua interpreter detected it as nil. It turns out the fix
was simple--I had to quote the string, as follows.

\def\emptyOrNot#1{%
 \ctxlua{userdata.empty_or_not("#1")}%
}

It took me a while to figure that out, though, since the wiki example
does not show quotes.


indeed you need quotes

Here's the debugging info after enabling the graphics.locating tracker
(which I learned about at the very useful page
):

  graphics> inclusion > forcing format '1'

Re: [NTG-context] kerning with buggy libertine

Hi Hans,

this is a bug report thanks to Khaled:

   http://tex.stackexchange.com/a/126650/14066

In short: the font loader applies the kerning of libertine
version 5.3.0 even though this appears to be broken in the font.
Context translation of the example:

   \definefontfeature [kerning] [mode=node,smcp=yes,kern=yes]
   \definefont [libertineserifsmallcaps] [file:LinLibertine_R.otf*kerning]
   \definefont [libertinesanssmallcaps]  [file:LinBiolinum_R.otf*kerning]

   \def\demotext{Vacillate Vaccine Vapour Vanish Va...}

   \starttext
 {\libertineserifsmallcaps \demotext}\par
 {\libertinesanssmallcaps  \demotext}\par
   \stoptext

(Doesn’t occur in base mode.) The technical details are in the
thread Khaled references.


\showotfcomposition{file:LinLibertine_R.otf*kerning}{+1}{Va} \page
\showotfcomposition{file:LinBiolinum_R.otf*kerning} {+1}{Va} \page

You need to be more explicit (which font, where to download the 
problematic one, etc ... i downloaded the 5.3 version - i think - of 
ll). In what sense is it broken in the font?

This works here.

  \starttext
%% \externalfigure [cow]
\externalfigure [somefigure]
  \stoptext

The graphic somefigure is located in TEXMFHOME. You probably did not
set location to default.
