I expanded on the description to make it clearer (hopefully). However, as I was 
testing, I realized that the remark about math font sizes ("These quick font 
switches [...] do not change the bodyfont, so they don't affect [...] math font 
size") is no longer true. In LTMX, \tfa correctly scales the math font size as 
well. 

\starttext
\tfc x$x$x
\stoptext

I am not sure when this behavior changed, but looking at some of my old 
documents I see that I have been using "\tfc $+$" in some of my tikz code for 
about 4 years. So, it appears to be a old feature. I am thinking of changing 
the wiki from:

These quick font switches are meant for changing the font style, alternative, 
or size of a few words: they do not change the bodyfont, so they don't affect 
interline spacing or math font sizes

to 

These quick font switches are meant for changing the font style, alternative, 
or size of a few words: they do not change the bodyfont, so they don't affect 
interline spacing.

(so not mention math at all). Let me know if I am misunderstanding something 
here.

Hi,

the wiki (https://wiki.contextgarden.net/Font_Switching) currently says:



These quick font switches are meant for changing the font style, alternative, or size of a few 
words: they do not change the bodyfont, so they don't affect interline spacing or math font 
sizes. So, if you want to change the font size of an entire paragraph, use 
\switchtobodyfont described below 
in Complete Font 
Change. However, it is 
fine to use them as style directives in setup commands, that is, using them as an option for 
style=... in any setup command 
that accepts style option

 From this, I'd infer that a  or  should change the 
interline spacing as well. But it does not seem to be the case as the example below shows.

Using style=\tfx is roughly equivalent to typing `\tfx` at an appropriate 
place. There is no automatic \setupinterlinespace after the style value is 
executed.


There is always the option to use \switchtobodyfont to change the font 
size which affects also the linespacing but in this case one need 
\setupinterlinespace after \tfx.


In older versions (a few months ago) even \switchtobodyfont didn't help 
here when you used the style-key to change the font size.

To change interlinespace you need either to use \switchtobodyfont[x] or
\tfx\setupinterlinespace.

In my experience, \tfx doesn’t behave in a different way as a value for
a style key than in standard text.

Just in case it helps,

Pablo

Using style=\tfx is roughly equivalent to typing `\tfx` at an appropriate 
place. There is no automatic \setupinterlinespace after the style value is 
executed.

Perhaps, it will be a good idea to add a concluding sentence "However, the 
previous caveats (no change in interline space or math font sizes) still 
apply".

Re: [NTG-context] [formatting verbatim text]

Aparently all spaces after @etex get reduced to one only.
I'd expect that to happen inside @btex and @etex

Re: [NTG-context] \setupalign[height] and \setupalign[line] in LMTX

[denis.maier]

Hi,

sorry to be such a nuisance, but i'd still love to hear if I'm missing 
something or if something is going off the rails in LMTX.

Best,
Denis

Hi,

\setupalign[height] and \setupalign[line] seem to have no effect in a  LMTX. Do 
I need to change something?

Best,

That works indeed! Thanks.


Are there restriction on what context commands can be given inside the 
bgroup? e.g. I tried to include a highlight definition with white font 
on black background with an inframed, but that doesn't seem to work (in 
my definitions that is)

Re: [NTG-context] clubs and widows in columns

[mf]

Dear list,

is there a way to avoid clubs and widows in columns? I don't know, how 
it would be implemented, if the task is splitting typeset vertical list.


\setuppapersize[A7]
\starttext
\startcolumns[separator=rule,
               align={right,nothyphenated}]
\dorecurse{12}{→ one two three four five\par}
\stopcolumns
\stoptext

For a different task: are there some higher level commands in ctx than 
\vsplitprimitive to play with vbox splitting?




As a workaround, you could try switching to pagecolumns: since they are 
typeset as pages and then rearranged as columns on a page, I expect 
clubs' and widows' penalties to work as in a single page.

I've not tried, anyway.

Best wishes,
Massi

I don't know, but from the message it looks like some 'local' variables
is not saved and defined. I'm surprised that loading some mf file works
at all (because it also assumes some mf related definitions). I also
hav
eno clue if such a package adopts 'core' metafun code (and mpiv metafun
is different from mpii).


It's a generic, "pure" MetaPost package:

https://www.ctan.org/pkg/cmarrows 


that doesn't make it immune from clashes in used variables with differnt 
types ... metafun is more than plain mp so more can clash


Fonts are in /fonts/source/public in a TeX Live distribution, in case it 
helps.
i have a rather minimal tex setup so i can't run that (i'm not going to 
clutter my system now)
