[NTG-context] placing a wide float at the bottom

2018-02-10 Thread Henning Hraban Ramm
Ahoi,

while
\placefigure[bottom]{}{\externalfigure[hacker][width=\textwidth]}
works just fine,
I get "top" placement with
\placefigure[bottom]{}{\externalfigure[hacker][width=\paperwidth]}

I.e. if the figure exceeds \textwidth, bottom placement fails.
I’m actually trying to place page wide images including bleed.

I’d guess this is a bug. Or can I do anything about it?


Greetlings, Hraban

[NTG-context] To \getbuffer or to \input: which one is it better?

2018-02-10 Thread Otared Kavian
Hi all,

In a project using the \setvariables command of ConTeXt, a file containing more 
than 200 instances of a structure resembling (but with much more fields…)

\setvariables[talk]
[speaker={Dr Some Speaker},
title={Some title},
room={Some Room},
]

is input several times, in order to extract from these variables one or more 
informations to be typeset, for different types of documents. However I don’t 
know whether this is a wise solution, or is it better to define once and for 
all a buffer and then use the \getbuffer command for each of the different uses 
in my global document.

For now, unfortunately, I cannot come up with a minimal example because the 
question I am asking is about a real situation where nothing is minimal. That 
is why I am asking a general abstract question to understand the general 
philosophy underlining the buffer commands versus the \input command.

Thanks in advance for any hint: OK

Thanks Otared! Works like a charm!

Out of curiosity, could you explain the mechanics behind this? I know it is
a commonly used trick in TeX macro definitions, but I don’t know how it
changes TeX’s understanding of the tokes it parses.

Cheers,
Tim

When you create a new commands like this

\def\mycommand[#1]{...}

the brackets are delimiters for the argument of the command, i.e. when 
TeX sees
\mycommand it looks for [ and grabs everything intill ] as as argument. 
When you
out now a space (or start a new line) after ] in your definition of the 
command, e.g.


\def\mycommand[#1] {...}

TeX looks now for “] ” (right bracket followed by a space) as delimiter for
the argument of your command.

Re: [NTG-context] placing a wide float at the bottom

Works here with the code below. The same result with and without adding

Do you have an MWE?
