I tend to think there must be an automatic way to deal with the most
awkward cases. The problem is that there just so many.
What do you think?
I played a bit with what we have and in a next upload you can do this:
\startexceptions[de]
au{f-}{f}{ff}(f\zwnj f)asse
\stopexceptions
\showglyphs
\starttext
auffasse
then is like:
au\discretionary{f-}{-f}{f\zwnj f}asse
\stoptext
Oh, that looks interesting. So that would essentially be implemented
like hyphenation exceptions? Any drawbacks? Performance hit with large
exception lists? Kerning?
Just an experiment. I don't know when there will be an update because
first WS and I have to test and double check some new stuff as we
don't want users to suffer too much from a couple of fundamental new
features.
Is there a patch so the brave can help with testing?
Best,
Denis

[NTG-context] font clarification
Can someone clarify a font issue for me please. I have the following setup: \definefontfamily[mainface][rm][TeX Gyre Pagella] \definefontfamily [mainface] [ss] [Arial][tf=file:arial:ttf] \definefontfamily [mainface] [mm] [TeX Gyre Pagella Math] \setupbodyfont[mainface,11.5pt] When I look at what this produces, I see that my body text is in fact texgyrepagellamath-regular. If I run mtxrun --script font --list --file -pattern=*pag*, I see, among others, the following: texgyrepagellamath ... texgyrepagellamathregular texgyrepagella-math.otf conflict: regular texgyrepagella ... texgyrepagellaregular texgyrepagella-regular.otf conflict: regular So three questions: 1. Does Tex Gyre Pagella Math contain everything I need for my body font (ignore Arial - I use that for drop caps and a few other things and it works as it should)? 2. If so, do I still need the first line in my setup, namely the [rm] line? Would not the [mm] be enough? 3. The mtxrun output suggests there is a 'conflict' between tgpagella-regular and tgpagella-math. What is the nature of this 'conflict'? It is possible that my questions reveal a basic misunderstanding of this typeface. Don't hesitate to tell me so but also try to put me right.

[NTG-context] figure library
I have used figure libraries in the mkII past. But my recent attempts with mkIV, following the instructions on ConTeXt Wiki (https://wiki.contextgarden.net/Image_Database), have failed. The following happens: 1. When running the command "context --input=figure-lib.xml auto:x-res-01.mkiv --result=figure-lib" in an EMPTY directory, 2 pages with buttons and titles are created. 2. When providing an image and an xml file (copied from the website above and including the image name and the missing ">" at the end), these are ignored -- the same 2 empty pages are created. Could somebody tell me what's wrong (with me, most likely)? Details: mkiV and LMTX, MacOS and FreeBSD, recent ConTeXt installations.

[NTG-context] bug with hz in LMTX?
Dear list,
I have the following sample:
\showframe\showgrid
\setuplayout[width=middle]
\definefontfamily[mainface][rm][TeX Gyre Pagella]
[features={default, quality}]
\setupbodyfont[mainface, 20pt]
\setupalign[hanging, hz]
\starttext
\dorecurse{25}{\input{zapf}\input{cuomo}}
\stoptext
On page 36 (https://pdf.ousia.tk/wrong-font-expansion.pdf#page=36),
lines 4, 11 and 20 are wrong.
Current LMTX (LuaTeX 2.07 20200920 + ConTeXt MkIV 2020.09.20 23:02) has
the issue, while MkIV (LuaTeX 1.11 7226 + ConTeXt MkIV 2020.01.30 14:13)
has no problem with that.
I think this might be a bug. Could you confirm the issue?
Many thanks for your help,
Pablo

The plain text version is already in the correct form: https://github.com/hyphenation/tex-hyphen/blob/master/hyph-utf8/tex/generic/hyph-utf8/patterns/txt/hyph-eo.pat.txt so it should be just a matter of Hans including the patterns in the distribution. Usually he asks for translations of basic strings (like "Chapter" etc.) when adding support for a new language ;) Mojca ___ 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 ___
[NTG-context] Hyphenation pattern for Esperanto
Hi!
I'd like to have hyphenation for
Esperanto; it doesn't exist in ConTeXt but exist in TeX/LaTeX.
Looking to the files, the French
hyphenation files for LaTeX and ConTeXt looks very much the
same. But for Esperanto there is a difference at the beginning:
--
\begingroup
% Makrooj por la finaĵoj:
\def\adj#1{#1a. #1aj. #1ajn. #1an. #1e.}
\edef\nom#1{\adj{#1} #1o. #1oj. #1ojn. #1on.}
\def\ver#1{#1as. #1i. #1is. #1os. #1u. #1us.}
%
\patterns{
a1 e1 i1 o1 u1 % ebligu tranĉon post la vokaloj,
2aj. 2ajn. 2an. 2as. % krom se antaŭ finaĵo,
-
The comments are in Esperanto. The
definition \adj, \nom and \ver are for adjectives, names and
verbs and are used in the file as:
% AĈ
\nom{1a2ĉ}
% AD:
\nom{1a2d} \ver{1a2d}
.avok2a3d .bal2a3d ĉokol2a3d .fas2a3d .inv2a3d kamar2a3d
.kan2a3d limon2a3d
persv2a3d .pom2a3d seren2a3d
% AĴ:
\nom{1a2ĵ}
% ALT-
Would it be difficult to create the Esperanto file for ConTeXt?
Thanks for your help and for ConTeXt.
Regards,
Alain Delmotte
