MetaPost indentation is tough. I have rewritten the indent script in Vim 
from scratch, and now it works reasonably well. I will try yours, but 
you might try the one currently in Vim, too.


I did not change metapost indenting, but defined some rules for indenting 
of context files. I believe that your indent file does not attempt to 
indent context files (I may be mistaken because I am just reading the .vim 
files, not testing it as I don't have vim8 yet).

I will look into those, too. Do you know that Vim has built-in support 
for digraphs (:h digraphs)? For example, α can be obtained by typing 
a* in Insert mode.


I know of digraphis but it can be tricky to remember all the mapping (for 
example for \subset, \circ, etc.). Auctex uses fairly intuitive shortcuts.


I could maybe create a GitHub repository, to make it easier to merge 
your work.


That will be nice. Then I can also send you pull requests for specific 
things.

Re: [NTG-context] Clickable question/answer numbers

[Mikael P. Sundqvist]

Dear Otared,

thank you again. This is somehow a proof that it should work. In my
real document I use the title to name some exercises (after old
exams), and I don't see how that can be combined with your solution.

If someone else reads this: I think the question boils down to the following:

\startquestion[Q:test]
How can I here automatically get access to to the string "Q:test"?
\stopquestion

Best regards, Mikael

A partial solution to the feature we are discussing is contained in the example

Ok, I will take a look. I see that your file does not depend on 
plaintex.vim. It might be a good idea to remove that dependency...

The syntax scripts in Vim already cover all of MetaFun. MetaFun keywords 
are highlighted by default inside ConTeXt documents; for MetaPost files 
('mp' filetype), you must put


  let g:mp_metafun_macros = 1

into your vimrc.

MetaPost indentation is tough. I have rewritten the indent script in Vim 
from scratch, and now it works reasonably well. I will try yours, but

Hi Nicola,

I wonder if you have seen my vim runtime files:

The main file to look at is the syntax highlighting file. I haven't compared

The metapost syntax highlighting file defines a few keywords that are used by

The indent file is adapted from (I think) latex-suite's indent file with

The ftplugin file mainly contains shortcuts like `a expand to α, etc; again,
adapted from latex-suite (which in-turn borred the idea from auctex). These

[NTG-context] interline space for \setuplist[alternative=d]

[Pablo Rodriguez]

Hans,

I have the following sample:

\setuppapersize[A6]
\setupinteraction[state=start, focus=standard]
\placebookmarks[chapter, section][chapter, section]
\startsetups[lsect]
\setupinterlinespace[line=28ex]
\stopsetups
\setuplist[section][style=\tfxx, alternative=d, setups=lsect]

\starttext
\completecontent
\dorecurse{5}{\chapter{Knuth}\input knuth
\dorecurse{8}{\section{Zapf}\input zapf}}
\stoptext

I cannot set the interline space for \setuplist[section]. Wolfgang
kindly provided me with a workaround:

\setuppapersize[A6]
\setupinteraction[state=start, focus=standard]
\placebookmarks[chapter, section][chapter, section]
\startsetups[plsect]
  \start
\setupinterlinespace
[line=2.8ex]
\placelist
[section]
[alternative=d,
 numbersegments=section,
 pagenumber=no,
 style=\itx] \par
  \stop
\stopsetups

\setuplist
  [chapter]
  [before={\blank[medium]}, after=\directsetup{plsect}]

\starttext
\placelist[chapter]
\dorecurse{5}{\chapter{Knuth}\input knuth
\dorecurse{8}{\section{Zapf}\input zapf}}
\stoptext

But the issue I discovered recently is that the first section links from
the table of contents reach the chapter destination (and not the first
section). Bookmarks work fine, instead.

Wouldn’t it be better to improve the alternative=d in \setuplist, so
that interline space could be set up with the setups option?

Many thanks for your help,

Pablo

Thank you again, Wolfgang.

Unfortunately I don't understand the syntax of \definefallbackfamily command
and therefore I only copy/paste examples I found in the list and context wiki.

I found the first mention of built-in simplefonts in this thread but it doesn't 
discuss
\definefallbackfamily in detail:
https://mailman.ntg.nl/pipermail/ntg-context/2013/075481.html

I also looked at context wiki pages for Command/definefontfamily
and Command/definefontfallback.

All in all I am very confused how to use the command.
It is not clear for me how to know if an option in \definefallbackfamily applies
to the font to be replaced or to  the replacement font.

--For example I guess range= option applies to the font to be replaced: if the
font/character lies within this range then it should be replaced by the font
defined in \definfallbackfamily. Is this correct?

--The preset= option is a predefined range; it is equal to some range= option.
Is this correct?

--What is offset=? Is this a range that should be used in the replacement?
Does [range=lowercasenormal,offset=lowercasesansserifnormal] mean that
lower case normal font should be replaced by lower case sans serif normal font?

--Does the above imply that offset= option is only valid for math fonts and it
can't be used for rm, ss and tt fonts?
(E.g. \definefallbackfamily [doc] [rm] [TeX Gyre Bonum] explicitly defines a 
serif font,
it would be nonsense to add offset=lowercasesansserifnormal option to the 
command.)

--tf=style:italic: what does this exactly mean? If the replacement font drawing
command is \tf then draw italic font? If yes, how it is different from
offset=lowercasesansserifitalic? Is this command used in the same manner
in \definefontfamily and \definefallbackfamily commands?

Thank you in advance,

bcsikos

Dear Otared (and list),

thank you for your reply and support.

The links from the answers to the questions work as wanted with my

not.

I guess I need something like

headcommand={\in{Question}[A:###]},

where ### is the reference tag I set. But I don't know what to change
the ### into (or if that would work).

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Mikael,

I had a similar question some time ago, but I wanted to add a sort of automatic 
referencing of questions and answers (and interaction going from questions to 
answers and back). 

If you accept the hurdle of adding manual references, in your case you can add 
(for instance…)

\goto{:-)}[Q:test]

to the end of your answer to go back to the respective question. But when you 
have several dozens of such references to add manually, it is not a good idea.

However I could not find a way to code the items (that is the questions) in 
such a way that each adds automatically a unique reference, and so I am 
interested too in the solution of the problem you mention.

Best regards: OK

[NTG-context] Clickable question/answer numbers

[Mikael P. Sundqvist]

Dear list,

I have a pretty large text with a lot of questions and answers, and
want the user(students) to be able to click in the pdf to go from a
certain exercise to its answer, and back. I have a solution (see
below) to go from answers to questions, but not the other way around.
I simply have no idea on how to make the red text (in the head) in the
example question clickable with the answer on the next page as target.
As you can see, the answer has a tag A:Q:test (I want to set these
automatically in that manner), and clicking the green text I get to
the correct place. I just don't see how to make the "Question 1.1"
clickable with that target.

I hope I make myself clear. If it matters, in the solution one could
assume that the optional tag of the \startquestion \stopquestion is
given for all questions.

Best regards, Mikael

[NTG-context] grid, interlinespace

[Michael Eidenbenz]

Hello

I want my text on a grid and there should be no gap between the top and the 
capital letters of the first line.
I managed to get this by changing the height parameter of \setupinterlinespace
with a factor I calculated for the font with this formula:

CapHeight/exheight / line = height

CapHeight and exheight are font specific numbers that I got from 
https://tug.org/TUGboat/tb34-2/tb107sharpe.pdf
for  lmroman this gives me: 683 / 431 / 2.8 = .566 for height in interlinespace

Although there is no gap to the top lines are jumping.
making the factor bigger helps. 
but smaller fonts wont snap to the grid.

What is happening here? 
And is this method of changing the height the right one?

Thanks Michael
