One can add units with \registerunit[unit] and \setupunittext (see line 652 in 
phys-dim.mkiv):

\starttext
\registerunit
  [unit]
  [minute=minute]

\setupunittext
  [minute=min]

\unit{45 minute}
\stoptext

However, I'm unable to explain what exactly \registerunit or \setupunittext 
does.

Of course, I'm also in favour of 2^3 to mean '2 cubed'.

I, for one, would expect 2^3 to mean '2 cubed', not 2x10^3. So I'd be
in favour of this change. Then again, I have no code that depends on

P.s. Isn't MkIV known to be unstable? I thought the official advice
was "If you want stability, use (a) MkII, or (b) a stable version of
MkIV, or (c) a dedicated standalone install that you do not update.

I think 'min' is parsed as 'meter nil nil', because (1) min is not
found in the list of short or long unit names, so it's assumed to be
composite; and (2) once processed composite, m-->meter-->m, while
i-->nil and n-->nil.
Solution: add 'min' to the list of short unit names (below).

Re: [NTG-context] Images in MultiMarkdown -> context -> PDF

2012-11-23 Thread Guy Stalnaker 
In case anyone else has been following this thread, here is the shell 
script I wrote to resize an image width to 6.5x72dpi so they fit in the 
standard letter pagesize \textwidth with 1-inch margins and add image 
density/resolution information so that context correctly sizes them in 
the PDF output file.



#!/bin/bash
#set -x

TEXTWIDTH="438" #6.5inches x 72 dpi

for i in *.jpg ;
do
SIZEX="$(exiftool -imagewidth $i | awk '{print $4}')"
SIZEY="$(exiftool -imageheight $i | awk '{print $4}')"
echo "Image $i is $SIZEX x $SIZEY, max X is $TEXTWIDTH ..."
if [[ $SIZEX > $TEXTWIDTH ]] ; then
convert $i -resize $TEXTWIDTH -density 72 $i
echo "resized image $i from $SIZEX to $TEXTWIDTH."
fi
done


Regards,

Guy

I think you don't want -resample, but -density:

# density given in dpi
convert pic.jpg -density 72 pic-out.jpg

convert -density keeps the pixel size and changes the display size by
setting the density metadata.
convert -resample keeps the display size and changes the pixel size by
resampling at a certain density. (This explains why the picture
remained the same too-large size when you resampled at 72 and 300
dpi.)

Because you want to change the display size (and also because
resampling is a lossy process), I think you want -density.

As for the density value you want to use:
Your picture is 547px wide, so if you want it to display it 3 inches
wide you should set its density metadata to 547/3 = 183 dpi.

Does this work?
All the best,

For example, in French, 1000 can be une brique, une patate or un bâton,
but I guess that this is not quite the same thing as the subject

Singular and plural don't always suffice.

Similarly for Polish (which is no surprise), so a more general mechanism

And similarly for thousands.


first we need working prototypes for several languages, then I can wrap

Put \setupalign[nohz] before and \setupalign[hz] after your chapter.

Hi all, Wolfgang,

coming back to a pretty old question because it doesn't appear to work.
For the book I'm currently typesetting, I had to disable expansion for
the entire document because it messed up spacing with Greek letters and
certain accents. Now the question is the other way round: can I enable
expansion only for certain passages? I'm in the final revision, and
expansion would help me take care of a few overfull hboxes. But while
setting \setupalign[hanging,hz] for the entire document does take care
of those, doing something like

\start
\setupalign[hanging,hz]
blablabla
\stop

doesn't have any effect. Is this possible at all, or am I barking up the
wrong tree?


You need to load a font with the expension feature enabled. After that 
you can enable/disable it using setupalign.

The '^' and 'e' all print a '10 ×' at the begining. It's what is expected for 
'e' but not for '^'. Did I miss something?

i patched your version a bit:

local crap = [[

Well... kinda... yes. ;P

You might want to look here for inspiration:

http://tex.stackexchange.com/users/323/aditya?tab=answers

(Clarification: joking aside, I guess that Aditya's habit of giving
ConTeXt answers to LaTeX questions on TeX.SE is really great, since
it allows to spread the word about ConTeXt, and also may help ConTeXt
users.)

By all means add it to
http://wiki.contextgarden.net/Math_fonts

That page is an overview of math+font issues in ConTeXt, from 'how to
use' to 'how to fix'; but math fonts are not that common, so it might
as well double as a list of math fonts per se.

Wiki: adapted. (Page created, actually, as there was none.) Using the
fancy-schmancy {{since|2012|text=nov 2012}} template, which (1) marks
this as a recent feature, and as such not in the stable yet, and
(2) sticks it in the hidden categories [Since] and [Since 2012], so
that we may review (and remove) those tags when the new stable comes

Hi Hans,

although csv is not a standard per se there is nevertheless an
rfc: . Can we have an
optional rfc-compliant parser as well? That entails interpreting
the first line as field header if it consists entirely of
unquoted fields -- neat feature as one can treat these as column
identifiers to query fields in a more natural fashion.

local P, R, V, S, C, Ct, Cs, Carg, Cc, Cg, Cf = lpeg.P, lpeg.R, lpeg.V, lpeg.S, 
lpeg.C, lpeg.Ct, lpeg.Cs, lpeg.Carg, lpeg.Cc, lpeg.Cg, lpeg.Cf

local lpegmatch = lpeg.match
local patterns = lpeg.patterns
local newline  = patterns.newline

--RFC 4180 csv parser

-- based on http://tools.ietf.org/html/rfc4180
-- notable deviations from the RFC grammar:
--   · allow overriding “comma” and “quote” chars in spec
--   · the “textdata” rule is extrapolated to mean, basically,
-- “everything but the quote character”, not just the character
-- range as in the RFC
--   · newline from l-lpeg.lua instead of “crlf”

local rfc4180_spec = { separator = ",", quote = [["]] }

utilities.parsers.rfc4180_splitter = function (specification)
specification = specification or rfc4180_spec
local separator   = specification.separator --> rfc: COMMA
local quotechar   = P(specification.quote)  -->  DQUOTE
local dquotechar  = quotechar * quotechar   -->  2DQUOTE
  / specification.quote

local separator   = S(separator ~= "" and separator or ",")
local escaped = quotechar
  * Cs((dquotechar + (1 - quotechar))^0)
  * quotechar
local non_escaped = C((1 - quotechar - newline - separator)^1)
local field   = escaped + non_escaped
local record  = Ct(field * (separator * field)^0)
local name= field -- sic!
local header  = Cg(Ct(name * (separator * name)^0), "header")
local file= Ct((header * newline)^-1 -- optional header
 * record
 * (newline * record)^0
 * newline^0)
return function (data) return lpegmatch (file, data) end

OK, it works again with 2012.11.22 18:09. I'm just wondering: the help 
information is always at the very bottom of the list of commands, so one 
has to scroll all the way down (and there's no obvious way of seeing 
that something has happened at all unless one scrolls down) - has this 
always been the case? I seem to remember that it would open a frame in 
the main window, but I may be wrong.

The table *is* the workaround ;P As long as you don’t mind being
limited to columns on one page, the tabulate syntax and the
restrictions on the input order, you’ll definitely be fine.

The additional code was supposed to show how to handle an issue
that is very likely to manifest itself with what you are doing:
translations of this kind are usually accompanied by some special
pagination. Using plain counters for that can have undesirable
side-effects.

Regards
Philipp
