Many thanks for your answer, I appreciate it!

If you look at the example below (output attached), you see that the
version with \bigl and \bigr has a different size than the other ones.

So my question boils down to: Is it possible, by using fences, to have the
same size as the \big, \Big, \bigg etc would give?

If not, is it possible to implement? I think it would make the already very
nice fencing system even more usable. The reason is to be able to use this
instead of not using fences at all in the few cases where the size from the
fencing is not optimal.

Dear Hans and others,

I'm usually use the \big, \Big, \bigg etc to get the size of
parentheses, brackets and braces to be the size I want. I realize
that the fences machinery is probably a cleaner way of doing this.

I tried it a bit, and it usually gives the result I like. But
sometimes not, and it seems that the way to change the size of the
parentheses/brackets/braces is to use the factor key.

1) Are the different options none, auto NUMBER explained somehere?
2) Could one have, for exceptional cases where the default is not
satisfactory, a keyword like factor=big for example, to get the same
size as if one would have used \big?

I am a bit confused. See the example below, with output (from latest
standalone) attached.

PS: I would suggest to have
  italic       = { feature = 'ss01', value = 1, comment =
"Mathematical Alternative Lowercase Italic" },
set in lucida-opentype-math.lfg. In all books (on math) I have seen,
I think this is what is used.

Ah, thanks! I had /opt/context/tex/texmf-cache/luatex-cache writeable,
but even /opt/context/tex/texmf-cache must be writeable, then it works.

The \doiffile macros recognize the existence of a file but, unless I 
am mistaken, not the existence of a directory.
Is there another macro, whose existence I have nof found yet, that 
offers this capability?
Or should this be a slight encouragement to expand the implementation 
in that direction?

Hi Tomáš,

both issues (the one from this thread and the question with hanging
punctuation) are fixed in latest beta.

You may install the latest beta from the ConTeXt Suite (aka ConTeXt
Standalone [http://wiki.contextgarden.net/ConTeXt_Standalone]) besides
your TeX Live installation.

The ConTeXt Suite is portable, so it won’t interfere with TeX Live. In
fact, I keep previous versions and I have fifteen different betas on my
computer (I only use the latest one, but it is wise to keep old versions
just in case some relevant functionality is compromised in latest version).

In the past, I was also reluctant to use beta versions. But after a
reply to one question of mine in this list, I realized that I may use
the latest beta version, besides TeX Live or the latest stable from the
ConTeXt Suite.

Instead of invoking:

  contextjit document.tex

I had to invoke:

  source path-to-context-beta/tex/setuptex && contextjit document.tex

The minor difference (I guess you don’t type the command) allows you to
use the latest version of ConTeXt.

After all, I guess this is much easier that trying to fix ConTeXt from
TeX Live 2017.

Just in case it helps,

Pablo
