Dear Hans,
Many thanks for your detailed guidance. I think for now this patch should
suffice for my simple needs.

In this font it's problematic though because the cv.. features have multiple loopup tables, one of which is a "multiple" lookup (used to decompose characters before applying the replacements, especially decomposing i into the stem and the dot) and another one is an "alternate" lookup providing multiple character variants.

Maybe the feature could be adapted to only interpret the argument as a replication factor if the "multiple" is the only lookup for the feature or if no other lookup for the feature is an alternate lookup?

Mamy thanks for your reply, Hans.
I think this might be simpler for me:
\starttext
\startluacode
function document.transfer_metadata(name)
local main_doc = lpdf.epdf.load(name)
lpdf.addtocatalog("Lang", lpdf.string(main_doc.Catalog.Lang))
lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title))
lpdf.addtoinfo("Subject", lpdf.unicode(main_doc.Info.Subject))
lpdf.addtoinfo("Author", lpdf.unicode(main_doc.Info.Author))
lpdf.epdf.unload(name)
end
\stopluacode
\unexpanded\def\TransferMetadata#1%
{\ctxlua{document.transfer_metadata("#1")}}
\null
\TransferMetadata{name.pdf}
\stoptext

It depends on how one has data in the csv, You can patch mlib-scn.lmt
(line 659)
if type(v) == "table" then
return injectpath(v,connector,close)
elseif type(v) == "string" then

else

then a string represents a function:

we can of course have some predefined and when we can agree on how these

As soon as documents become more complex and one wants control over th elayout all these alternative-to-tex formats in the end are not better than structured tex input. The simpler the input tagging, the more complex the escaping from that. So in the end it all depends on what kind of documents one has to deal with. And it's all about abstraction and structure: the more, the easier.

indeed the interfaces in lmtx/luametatex are better than in mkiv/luatex
and new things will only be done in lmtx
anyway, context users most likely will move to lmtx (mkiv is not really
frozen as it is also the test case for luatex, but there will be no
fundamental new things added)
so, if your source uses a limited set of commands you can write a parser
(in any language)
This parser would need to understand TeX source files and conventions
such as % for comments, recognise commands starting with \ and with
arguments/parameters bracketed by [] and {}, and look up command names
that might be written in Lua, then call them.
Isn't that what LuaMetaTEX does? No, I haven't looked at the actual source
code yet, but starting with something that already does most of what you
want is always quicker than writing from scratch.
sure, any tex engine is better at parsing tex input
the main differences between luatex and luametatex (much is disucussed
in articles and manuals) is that luametatex has no backend built in and
has some better interfaces in the front end; there are extension to the
subsystems of the tex engine (fonts, language, math, inserts, marks,
alignments, conditionals, macro definition, par handling) that are not
in luatex (which is basically frozen in order to permit other macro
packages to support it); lua helpers have been cleaned up and there are
some more; luametatex has a smaller binary, is more efficient wrt memory
and has better performance (if used well) than luatex

A better alternative to tex4ht / tex4ebook would certainly be much easier for me, even if I'm still somewhat offended by the intermediate steps. As for xml or pandoc, I'd rather not because I want to keep print (PDF) as the primary output, and I don't want to lose what TeX/LaTeX can do that most markup languages can't. From what I know of pandoc, it is like Sphinx in that the way it generates PDF output is by translating pandoc into LaTeX/TeX, then running TeX! So instead of my current toolchain where I write the LaTeX I want directly, I'd be examining the pandoc output and if it isn't what I want, poking at pandoc in the hope of making things better. It may be unfair, but my impression is that TeX and typesetting / layout systems based on TeX can do more interesting things than say XML or Sphinx. Moving to a more "universal" markup format might broaden my options, but I don't want a lowest common denominator solution. -- cheers, Hugh Fisher ___ 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 ___

I'll be trying out Metapost as a replacement. My markup isn't that complicated, so at worst I could translate by hand.

[NTG-context] Changing the style of author’s surname in a custom bibliographical style
Greetings,
I am trying to make a bibliographical style that would comply to the ISO
690 standard and I have a few questions:
1) The name of the author need to be written in the inverted format
(e.g. Knuth, Donald). It is also customary to write the surname either
in uppercase or in small caps (e.g. KNUTH, Donald). If I wanted to
change the whole name to small caps I’d do something like this:
\btxdoif {author} {
{\sc \btxflush{author}}
\btxperiod
}
How do I change the “font” of the surname only? Can this be done by
redefining a TeX macro (like in BibLaTeX’s \mkbibnamefamily) or is this
done by changing some Lua code?
2) As I have said, the name has to be inverted. This is done by setting
authorconversion to inverted. I’ve tried doing this like this:
\setupbtx[iso690:list][authorconversion=inverted,]
and this:
\setupbtxlist[iso690][authorconversion=inverted,]
Neither of these options work, but this works:
\setupbtx[default:list][authorconversion=inverted,]
I’m confused—why does changing the default option work and changing the
option for my style doesn’t?
Here's a MWE for both of my problems:
% publ-imp-iso690.mkiv
\startbtxrenderingdefinitions[iso690]
\definebtx
[iso690]
[
default=default,
specification=iso690,
]
\definebtxrendering
[iso690]
[
specification=iso690,
numbering=yes,
]
\setupbtx[default:list]
[
authorconversion=inverted,
]
% field definitions
\starttexdefinition btx:iso690:author
\btxdoif {author} {
\btxflush{author}
\btxperiod
}
\stoptexdefinition
% book definition
\startsetups btx:iso690:list:book
\texdefinition{btx:iso690:author}
\removeunwantedspaces
\stopsetups
% publ-imp-iso690.lua
local specification = {
name = "iso690",
categories = { },
}
local categories = specification.categories
categories.book = {
required = { "title" },
optional = {"author"},
}
return specification
Thanks for your help,
Tomáš

Re: [NTG-context] Weird error when using \startformula inside lua
On 9/11/2021 5:11 AM, Aditya Mahajan via ntg-context wrote:
I sometimes define lua functions for showing out worked out calculations. The
following minimal example shows that
context([[\startformula ... \stopformula]])
fails in LMTX with an error message:

sequence \undefined
MWE:
\startluacode
thirddata = thirddata or {}
local comment = [[
This is a famous formula
\startformula
a^2 + b^2 = c^2
\stopformula
]]
function thirddata.explanation()
context(comment)
end
\stopluacode
\starttext
\ctxlua{thirddata.explanation()}
\stoptext
The actual use case is more complicated (where I use templates, so I don't want
to convert everything to context.startformula() etc.). The example compiles
with MkIV but not LMTX.
Any idea what is going on?
\enabletrackers[context*]
shows that we have an unprotected \startformula so we need this in
strc-mat.mkxl:
\permanent\protected\defcsname\e!start\v!formula\endcsname{\strc_formulas_start_formula{}}
\permanent\protected\defcsname\e!stop
\v!formula\endcsname{\strc_formulas_stop_formula}
\permanent\tolerant\protected\def\defineformulaalternative[#1]#*[#2]#*[#3]%
{\frozen\instance\protected\defcsname\e!start#1\v!formula\endcsname{#2}%
\frozen\instance\protected\defcsname\e!stop #1\v!formula\endcsname{#3}}
(the \protected probably got lost when i added overload protection etc)
