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

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?

[NTG-context] Passing macro parameters to lua
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{%
\ctxlua{userdata.empty_or_not(#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.

Re: [NTG-context] \externalfigure doesn't find mps file in subdirectory
Hi Sanjoy,
Sorry for the late reply; I had to dig around in grph-inc.lua, and I'm
a bit rusty at source-diving.
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!
Cheers,
Sietse

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

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

\savebuffer [list=component, file=bib-component.tex, prefix=no]
\setupinteraction [state=start]
