[NTG-context] Number formatting in \unit
All, I have put together some suggestions to extend the number formatting capability in \unit, particularly for scientific and engineering purposes, including basic support for tolerances and uncertainties. It is a bit long, so source is attached and a PDF is at http://dl.dropbox.com/u/36891398/units6.pdf Of course, this is just my opinion, so I welcome any feedback from the list.

I like your suggestions. Especially the current handling of `e-23` etc. is not intuitive but rather confusing and does not meet the standard. I do not know if there is already a solution for automatically shortening the number of digits in the output, but that would be nice, too.

I just wanted to bring this topic up again since it is still
reproducible with ConTeXt MKIV 2011.11.25 21:29.

Yes, it does.

Using XITS it does also work although in display math mode(?) ∫ and
$\intop$ are not scaled.
I use the following example.
\setupbodyfont[xits]
\setupinteraction[state=start]

directly like $∫$ or $∩$.
But $\int$ by \type{\int} and $∫$ by UTF-8 character look differently.
As Mojca pointed out \type{\intop} is also not type set correctly: $\intop$.
This suggests that it is a problem with the Latin Modern font. \type{\intop}
was added in \from[context2008].

Is there a chance to fix `\intop` in Latin Modern (and XITS).
Would it be a good idea to map ∫ to $\int$ instead of `\intop`? Do
people use `\intop` a lot?
Thanks,

Sorry for being a noob. I thought for the first three that is somehow
done already. If not, such a mechanism would indeed be useful.

Have a look at char-def.lua. All the symbol mappings are defined there.
Please feel free to complete the table (it is a boring and time consuming
process, and I have only managed to cover about half of the table).
Regarding your mappings, IIRC -> etc are mapped to \rightarrow etc, (not
\xrightarrow). We can talk about including style variants for the
mappings.

Re: [NTG-context] ∫ and $\intop$ is not displayed correctly compared to $\int$.
wow, there is really much magic going on in context. one reason why i love
it.
i once wrote a script that showed some nice little gui for a similar file
(i.e. xkb/symbols/??) that displayed the characters on a grid similar to
the keyboard layout and allowed displaying of the different layers. i used
it to customize the standard ubuntu keyboard layout to have some much-used
symbols, but haven’t really got around to try switching to another layout
than quertz (as it would tie me even stronger to my own pc and would take
significant time to master)
maybe it would be nice to have a similar program that displays the mappings
in the char-def.lua since i can’t search for the symbols directly, have no
overview and editing would involve looking up the codes or names in a char
map, finding it in the file, and so on.
xrightarrow and friends are nice, because they adjust their length to the
over-and underscripts and work without parameters, too. so $A → B →{woo} C$
would work flawlessly and look nice both in code and the document.

[NTG-context] wider right margin when it shouldn't be
Hi there,
compiling this document:
\setuppapersize[A4]
\setuppagenumbering[alternative=singlesided,location=middle]
\starttext
\showsetups
\dorecurse{4}{\input dawkins \par \input knuth \par}
\stoptext
I should get the exact same length for left and right margin (defining
margin as the total distance from the page edge to the text body edge
[sorry, it isn't as accurate as it should, but I would like to avoid
misunderstandings]). Setups show also that margin width and distance are
equal for both sides.
What I see on my laptop (and what I have seen on the printed version) is
that the right margin is wider than the left one. Is there something
wrong or which is the measure I'm missing?
Thanks for your help,
Pablo

The margins are unrelated to the position of the left border of the text block.
ConTeXt use the value from “backspace” for the inner (left) space and the
“cutspace”
value (normaly calculated by ConTeXt when you set a value for “backspace” and
“width”)
for the space on the outer (right) side.
These are the three values for the horizontal dimensions:
| backspace | width | cutspace |

Why MkII? MkIV is much better for this.

Brr... Or you have to have to define an encoding that includes the 02BE
02BF chars. I wrote an article on that, and I NEVER want to go back to
that again, ever :-)
Now we can do better, at least in LM. In MkIV, we simply:
\starttext

For Muslims, {\em ʿišaʾ} is the last prayer of the day.
For Muslims, {\it ʿišaʾ} is the last prayer of the day.
\stoptext
The italics/slants look better, no need to fight with italic correction
etc. I use a transliteration keyboard on Windows that I can send you if
you like.
Anyway: It's time to switch to MkIV, my man :D

get the following error.

[NTG-context] MnSymbol (math) support in ConTeXt
Hello, I have been developing a new layout environment using Adobe Minion Pro for the main body font. My document will include a significant number of math formulas. I found a thread from earlier this year on the possibility of adding support for the LaTeX MnSymbol font package in ConTeXt, and wondered if anyone has gone farther with this idea. The last recommendation on the thread ( http://www.ntg.nl/pipermail/ntg-context/2011/057426.html) was to merge the Opentype MnSymbol font with Minion Pro using FontForge -- I tried that using the steps outlined, but reached the same obstacle mentioned by the last poster: the new (merged) font is not recognized by ConTeXt. That approach probably violates the Adobe font license anyway... In a 2009 thread on dev-context, Wolfgang Schuster mentioned an attempt to create a virtual font and typescript for MnSymbol, but he encountered problems with Greek characters. ( http://archive.contextgarden.net/message/20091122.164136.5757ec1f.en.html) So, as I don't know how to proceed further, I would be interested in hearing from anyone who has experimented with MnSymbol support, or in finding out what specific steps would be involved in adding support. Also, any recommendations of other math fonts suitable for use with Minion Pro would be welcome. I am currently playing with XITS math, which is Times-like but not too bad a fit.

I didn't check you code (try to make a minimal example
next time), but the problem seems to be the combination of
equations and labels. When labels are present, the file is
processed twice and the equations are also read twice (in
MkIV). It hasn't been fixed for ages, that probably means
it will stay.
One workaround is to substitute the equations with
assignments or to “save” the values beforehand.

Why do you say that you compile the latest source of gnuplot (which finally has context terminal built in, after 5 or 6 years), and yet you use the "mp" terminal instead of the default "context" (or at least "tikz")? The mp terminal has been there forever, and hardly ever improved. It also doesn't integrate too well (if you change the typeface, that won't be reflected in you plots).

However if the Lua code did interpret the number into an internal format it would enable other things like normalisation to scientific or engineering form, etc. However the internal format would have to support arbitrarily long numbers and exponents ... Lua's built-in internal number format (a double precision float, I think) would not do, so there would be a bit of coding involved.
