[NTG-context] running head for TOC
I have a very long Table of Contents (runs across five pages) and the
author would like the running head on recto pages for this to be 'Table
of Contents'.
I am using the following to create the TOC head:
\definehead
[tochead]
[title]
\starttochead[title={Table of Contents}]
\setupheader[state=start]
\placecombinedlist[content]
\stoptochead
And I use the following to set up the headertexts for the book as a whole:
\setupheadertexts
[{\hfill\getmarking[chapter]\hfill}][] %recto pages
[{\hfill\documentvariable{metadata:title}\hfill}][] %verso pages
The problem is that I am unable to get 'Table of Contents' as a running
head for the two recto pages where I need it. I realise I need to get
'tochead' recognised somehow for this. If I set up a separate
\setupheadertexts [{\hfill\getmarking[tochead]\hfill}][] then I end up
with 'Table of Contents as the running head on all recto pages, which I
don't want.
Can anyone suggest how can I get 'Table of Contents' as the running head
just for the two recto pages of a five page TOC?

[NTG-context] 3 questions about xtables after reading manuals
I've been trying out xtables and reading the manual, some things I can't
find how to do (or if it's possible on xtables):
1. How to align whole columns. It seems I have to add [align=middle] to
each cell I want to have centered in a raggedright aligned table. In
tabulate you can use [|l|c|] to do this, is it possible in xtables? Seems
weird if it's not. Or did I miss something?
2. I know how to use [option=stretch] to fill the textwidth, but can I make
specific columns "tight", so they don't get stretched beyond their content?
3. When I use [option=tight] sometimes columns are narrowed so much as to
break a line of 4 or 5 words. MWE:
%
\startplacetable[location=none]
%\startxtable[align={middle,lohi},option=tight] % This makes the first
column too narrow. Lines are not that long
\startxtable[align={middle,lohi}]
\startxtablehead[head]
\startxrow
\startxcell[align=right] \strong{Concepto}\crlf\small{Cifras en miles de
pesos} \stopxcell
\startxcell \strong{Dato} \stopxcell
\stopxrow
\stopxtablehead
\startxtablebody[body]

\startxcell[align=right] Bono \stopxcell

\startxcell[align=right] Valor nominal \stopxcell
\startxcell \$100\,000 \stopxcell

\startxcell[align=right] Tasa cupón - periodicidad anual \stopxcell

\stopxtablebody
\stopxtable
\stopplacetable
Can I make this table to be "tight" but only so much as to allow "short
lines" (i.e: lines that don't make the table go wider than textwidth). I
can do it with manual width, but wondering if it's possible.
Thank you .

I got curious about those staircase kerns. Is there a simple example that
shows their effect? I greped the source, but did not find anything where I
could see a difference.

[NTG-context] lmtx
Hi,
There's a new lmtx upload with a few fixes in publication lists (TS made
some tests).
For those who like fonts, there is an update of the punk font (the mkiv
variants dates from 2008 which is ancient on a software timeline).
You can run
meta-imp-punk.mkxl
to get an idea. There's also a typescript:
type-imp-punk.mkxl
one can create different versions and play with random variants and
such. The question is: do we need more metapost font magic and
infrastructure?
For "pdf features that browsers implement fuzzy or not at all" lovers
there is
test
\startalternate[text={A}]
\dorecurse{10}{A }
\startalternate[text={B}]
\dorecurse{10}{B }
\stopalternate
\dorecurse{10}{A }
\stopalternate
test \par
test \startalternate[text={e=mc^2}]!$e=mc^2$\stopalternate\par
test \alternate{e=mc^2}{copy:}\nbsp$e=mc^2$\par
which cheats on cut and paste (if you know where to click). (It actually
will replace something more low level which is probably not used
anyway.)

You were (attempting to) redefine the macro’s arguments, but they are read-only. A somewhat longer answer: the type of macro arguments in this case is “expr”. Metapost argument types are based solely on what the internal language parser needs to interpret the code; the language is not strongly typed. Also, during macro expansion, your code is replaced by: %numeric (READONLY TEMP VALUE 1); %numeric (READONLY TEMP VALUE 2); draw unitsquare scaled 10 xshifted (READONLY TEMP VALUE 1); draw unitsquare scaled 10 yshifted (READONLY TEMP VALUE 2); Best wishes, Taco — Taco Hoekwater E: t...@bittext.nl genderfluid (all pronouns) ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
