Thanks Hans - I never thought to look in the test cases (d'oh!).

For the benefit of those searching the archives in the future, here is an MWE 
adapted from one of the test cases that places one bookmark via a chapter 
heading and one manually that is not linked to any document section.

\enabletrackers[references.bookmarks,backend.resources] % For debug only

\setupinteraction
  [state=start]

\setupinteractionscreen
  [option=bookmark]

\definelist
  [mylist]
  
\placebookmarks[chapter,mylist]

\starttext
\input zapf
\bookmark[mylist]{Bookmark not linked to a section heading}
\input zapf

\page[yes]
\startchapter[title=Tufte]
\input tufte
\stopchapter
\stoptext

I shall add it to the Wiki.

Hello all,

I am the one who posted issue #20 for the font back in January 2018. The 
report simply states that there is no way to get dlig without also 
getting hlig, and includes an easily reproducible demonstration (using 
LibreOffice on the assumption that it is more accessible for testing). 
Since then, there has been a PR submitted. Crickets. No action.


As to which version of the font should be used, Georg Duffner 
transferred stewardship of the font to Octavio Pardo in 2017 or so. 
Pardo added support for faces beyond roman and italic (bold, semibold, 
extrabold). Some work was done a couple of years ago to support variable 
fonts, but nothing that can be used has yet come out of that effort. To 
a casual observer, the development and maintenance appears to be 
abandoned. I am sure that many would be happy to see work on this font 
resume, but projects like this are difficult to take over and support is 
thin.


So, if you can find that satisfies your requirements as it is, use it. 
The Duffner versions (pre-Pardo) do not have this particular issue, and 
if you do not need emboldened faces or other updates Pardo may have 
implemented, that should work. Or look elsewhere. Although the range and 
licensing of EB Garamond was certainly attractive, there are plenty of 
Garamonds in the world.

Interesting.

Here is a an example that sort of works, Variant 1:

\setupbodyfont[english,10pt]
\starttext

Variant 1:

However, it turns of *all* the ligatures.

Here is an example that works as expected, Variant 2:

\definefontfeature[english][dlig=no]
\definefontfamily[ebgaramond] [rm] [EB Garamond]
 [features={default,english}]
\setupbodyfont[ebgaramond,10pt]

It turns off just the ct and st ligatures.

Did you enable interactions? \setupinteractions[state=start]

But when I recently tried to manually set some bookmarks instead of visible 
chapter titles, I also didn’t get any; didn’t investigate further yet.

there are some examples in the test suite (sections/bookmarks-*.tex)

You can specify bookmarks when you use \startsection etc an dalso add 
them any place to named lists.

Hi Kurt,

here you have the sample that should work:

  %~ \definefontfamily[ebgaramond] [rm] [ebgaramond]

%~ [features={default,dlig=no}]

  \definefontfeature[english][dlig=no]

  \definefontfamily[ebgaramond] [rm] [EB Garamond]

[features={default,english}]

  \setupbodyfont[ebgaramond,10pt]

  \starttext

  ct st

  \stoptext

BTW, on my system the default doesn’t get discretionary ligatures.

Your sample didn’t work because the identifier for \definefontfamily
(english) was different from the one used in \setupbodyfont. (If they
don’t match, it cannot work.)

Another cleaner approach is to define font features to invoke them in
\definefontfamily. This method seems cleaner to me.

I hope it helps,

Pablo

Sorry, there was a typo. Use this:

\setupbodyfont[english,10pt]

You'll need to use the alias for the font family, as follows:

\setupbodyfont[english,10pt]

Re: [NTG-context] How do I get rid of the ct and st ligatures in EBGaramond?

[Joey McCollum]

If you're using Octavio Pardo's version of EB Garamond (
https://github.com/octaviopardo/EBGaramond12), then these ligatures are
covered (along with the Th ligature) by the "dlig" (discretionary
ligatures) feature, so you'll need to disable that. Unfortunately, this
will also disable the Th ligature. This is a known, open issue for the
font: https://github.com/octaviopardo/EBGaramond12/issues/20.

I hope this helps.

Hard to say ... I think that the parser / expansion machinery in mp is

So yes I do need to implement it in ANSI-C wrapped in Lua (so that it
can be used from *inside* ConTeXt).


I would have to see the 'kind of code involved' in order to comment on 
that.


An option is to do most in lua and maybe some helpers for crititical 
code in C.

Many thanks for your swift and helpful comments.

After some *very crude* tests using the `luametatex` and `luametafun`
documents, I find that while I *can* stop effective processing at
various points in the LuaMetaTeX pipeline, the time difference overall
is not really significant enough to bother with this approach.

The principle problem is, as you suggested below, "stopping" the
pipeline at the PDF stage (using for example the `pre_output_filter`)
corrupted the `*.tuc` data which is for my purposes, critical.

Your comment was:


but keep in mind that multipass data is flushed as part of the
shipout (because it is often location and order bound)


For the record, using the `append_to_vlist_filter` callback, I did
manage to drastically reduce the "pages" (which were all blank, not
surprisingly).

However, on my elderly desktop from 2008, both callbacks essentially cut
only 6-8 seconds out of 18 seconds, for the `luametatex` document, and
190 seconds, for the `luametafun` document.


hm, on my 2013 laptop the luametatex manual needs 10 sec (i have all the 
fonts, so that includes a bunch) and a metafun manual should do about 20


a test on am M1 mini needs half those times as reported yesterday

i bet that on a modern desktop the luatex manual will do < 5 sec


In the case of the `luametafun` document, it is the MetaFun/MetaPost
processing which, of course, is taking a long time (as it should, the
graphics computations represent important but complex computations).


One run or many due to xref? Maybe your machine has no significant cpu 
cache? Do you run from disk or ssd? How much memory?



My ultimate goal is to parallelize the production of large, heavily
cross-referenced, ConTeXt documents... more on this in a future email...

This is a very good and important question. One I have asked myself
repeatedly.

My ultimate goal is to write a small mathematical kernel in ANSI-C,
which is, using [Frama-C](https://frama-c.com/), proven *correct*.

To my knowledge, Lua has no similar tool for correctness proofs.

Equally importantly, there are a very wide range of very different
compilers which compile ANSI-C for an equally very wide range of CPU's. 

Again, to my knowledge, Lua v5.4 has only one implementation (though
this implementation *can* be compiled for a very wide range of CPU's).

The problem here is that Mathematicians are inherently very
conservative about the concept of "proof" (it has taken well over 2,000
hard years to develop our current understanding). My kernel will be an
extensible "proof" engine. For mathematicians to trust it, this proof
engine must itself be proven correct (or as correct as currently
possible). It must also be simple enough to *see* that it is correct
(hence the Literate-Programming approach), *and* (since I can not even
hope to prove the compilers are *correct*), there must be many
*different* compiler implementations (to show that the results are not
artefacts of one particular implementation).

Finally, the computational complexity of my proof engine, will be
comparable to MetaFun/MetaPost... which I suspect you would not
consider implementing in pure Lua. Some things are faster in C.

So yes I do need to implement it in ANSI-C wrapped in Lua (so that it
can be used from *inside* ConTeXt).

Since this is a mathematical tool, "embedding" it in ConTeXt is ideal.

As a mathematician writes, what they write gets proof-checked
automatically... in the document they are writing, and by the
typesetting tool they are using for the finished PDF. :-)

ConTeXt (via LuaMetaTex) makes this possible in a way native TeX/LaTeX
never could.

So once again, many many thanks for the vision to create such a
flexible tool!

The test, which triggered the error message (above), was to prove that
I could send [NATS](https://nats.io/) messages from *inside* ConTeXt.

"Out of the box", the [Lua-NATS](https://github.com/DawnAngel/lua-nats)
requires:

- luasocket (which LuaMetaTex provides, many many thanks!)

- lua-cjson (which is an external shared library and is what I was
  testing)

Fortunately, I found a couple of pure Lua JSON tools which I could get
Lua-NATS to use with a one line change. (And, for the record, I *can*
send and receive messages from a NATS server from inside ConTeXt :-)  

If I find I need to make changes to the Lua-NATS code, I will probably
use LuaMetaTeX's internal JSON implementation as you suggest below
(again many thanks for embedding a JSON implementation).

Using Lua-NATS is part of my larger goal to parallelize the typesetting
of large documents using ConTeXt (more on this in another email).

Re: [NTG-context] Using ConTeXt-LMTX for modern Mathematically-Literate-Programming 1/2

[Stephen Gaito]

Hans,

Many thanks for your swift and helpful comments.

After some *very crude* tests using the `luametatex` and `luametafun`
documents, I find that while I *can* stop effective processing at
various points in the LuaMetaTeX pipeline, the time difference overall
is not really significant enough to bother with this approach.

The principle problem is, as you suggested below, "stopping" the
pipeline at the PDF stage (using for example the `pre_output_filter`)
corrupted the `*.tuc` data which is for my purposes, critical.

Your comment was: 

> but keep in mind that multipass data is flushed as part of the
> shipout (because it is often location and order bound)

For the record, using the `append_to_vlist_filter` callback, I did
manage to drastically reduce the "pages" (which were all blank, not
surprisingly).

However, on my elderly desktop from 2008, both callbacks essentially cut
only 6-8 seconds out of 18 seconds, for the `luametatex` document, and
190 seconds, for the `luametafun` document.

In the case of the `luametafun` document, it is the MetaFun/MetaPost
processing which, of course, is taking a long time (as it should, the
graphics computations represent important but complex computations).

My ultimate goal is to parallelize the production of large, heavily
cross-referenced, ConTeXt documents... more on this in a future email...

Again, many thanks for your comments!

Regards,

Stephen Gaito

Are those extensions only for VSCode or they should work with other
clients/editors (Emacs, Vim, ST) all of which have LSP support?
