[NTG-context] Both pdfinfo & exiftool have trouble with 1.0.4 but works with 1.0.3
Hi, We use PDF tools like mutool, pdfinfo (from poppler) and exiftool in our workflow (once the PDFs are created by ConTeXt). But looks like we have hit upon some regression issue between 1.0.3 and 1.0.4 versions. Both pdfinfo (from poppler) and exiftool are able to read PDFs created from 1.0.3 but have trouble reading PDFs created with 1.0.4. Please see below logs for details. Our 1.0.4 is from April-2021. We will try to upgrade to the latest 1.0.4 and try again. mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /ConTeXt/apr2021/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.04.21 11:39 mtx-context | main context file: /ConTeXt/apr2021/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.04.21 11:39 mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /ConTeXt/sep2020/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.09.20 23:02 mtx-context | main context file: /ConTeXt/sep2020/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.09.20 23:02 *pdfinfo (from Poppler)* ~/TeX$ pdfinfo Hello-world_1.0.4.pdf Syntax Error: Missing 'endstream' or incorrect stream length Syntax Error: Missing 'endstream' or incorrect stream length Title: Hello world!

That is not the case:
$ echo 'print("" == nil)' | lua
false

If you call luafunction(""), the string is empty and not nil.
\startluacode
userdata = userdata or {}
function userdata.macro(str)
if str == nil then
context("Argument is nil")
elseif str == "" then
context("Argument is empty")
else
context("Argument is %s", str)
end
end
\stopluacode
\define[1]\Macro{\ctxlua{userdata.macro([==[#1]==])}}
\starttext
\startlines
\Macro{}
\Macro{ABC}
\ctxlua{userdata.macro()}
\stoplines
\stoptext

[NTG-context] nil from TeX to Lua
In the TeX to Lua interface with
\def\Macro#1{\directlua{luafunction("#1")}}
the transfer from TeX to Lua is by string. However what to do at the Lua end
when calling \Macro{}?
As I understand it, then on the Lua side an empty argument and an empty string
are indistinguishable. This is not always wanted, for example when one needs to
place either a nil or an empty string into a Lua table. I am running in trouble
when to t.key set to \Macro{} should become nil or when it should become "".
Is there some common understanding about how to handle this situation?

[NTG-context] footnote interaction in titles
Hi,
I probably shouldn't use footnotes within titles, but I am misusing the
title elements for a quick interview style document (I use them in the ToC).
One thing I have noticed is that interaction style (color and styles) are
not applied in the footnote and footnote numbering.
Is that a side effect or intended like that?
A half-workaround is to apply the styles directly, but not sure how I can
force the numbering style (same-page reference).
See MWE:
\setupinteraction[state=start]
\starttext
\startchapter[title={Long question with footnote \footnote{see: \goto{
https://wiki.contextgarden.net}[url(https://wiki.contextgarden.net)]}
and with a workaround \footnote{see: \goto{\bf\startcolor[darkgreen]
https://wiki.contextgarden.net\stopcolor}[url(https://wiki.contextgarden.net
)]}?}]
\input knuth
\footnote{see: \goto{https://wiki.contextgarden.net}[url(
https://wiki.contextgarden.net)]}
\stopchapter
\stoptext
It is not crucial, and if the behaviour is intended as such because of the
title element, that is fine, I am just curious.
Thanks,
Adam

Re: [NTG-context] Create an enumeration style

Hi Wolfgang,
Thank you for your suggestion.
I tested the code and the result is not what I expected from the
second item : "2 exemple" instead of "2^{e} exemple", "3 exemple"
instead of "3^{e} exemple" ...
core-con.lua (line 1155):
local ordinals = {
[...]
french = function(n)
if n == 1 then
return "er"
+ else
+ return "e"
end
end,
}
Then I tried to use the key alternative = serried but without success.
This works for me:
\defineenumeration
[test]
[text=,
alternative=serried,
width=fit,
distance=.5em,
numbercommand=\groupedcommand{}{~exemple},
numberconversion=ordinal]
\mainlanguage [fr]
\starttext
\starttest
\input knuth
\stoptest
\starttest
\input knuth
\stoptest
\stoptext

Re: [NTG-context] Short forms and abbreviations in bibliography
Henning's suggestion for abbreviations should work fine for that issue. I
could simply use the shorthand in the "series" and "journal" fields and set
up the appropriate \abbreviation calls in the document or environment.
As for the larger issue of bibliographies, I've started working on
publ-imp-sbl.lua and publ-imp-sbl.mkvi files. I knew I would need this for
my own project soon, and I felt it would be useful to myself and the
ConTeXt community if I could at least get a rudimentary version working.
I'm presently using the reference for examples from the *SBL Handbook of
Style*, 2nd edition, available at
https://github.com/dcpurton/biblatex-sbl/blob/master/test/biblatex-sbl-examples.ref.txt
.
Like you say, some parts are tricky. SBL uses "entry"-style citations by
default and doesn't seem to make use of other common alternatives (such as
"authoryear"). I can think of some existing alternatives that might get
used in specific cases (e.g., "author", "title"), but the
recommended shorthand has the form "shortauthor, shorttitle" (i.e., the
last name(s) of the author(s) only, followed by a comma and a shortened
form of the title as specified in the "shorttitle" field). I could make
this the sbl style's implementation of the "short" alternative, since the
LaTeX-style bracketed number references are foreign to SBL style anyway,
but if would be preferable just to introduce another alternative (something
like "authortitle"), then I could also try to do that.
For my immediate purposes, I won't need much more than the @book, @article,
@inbook, and @incollection entries, so my focus will be on getting those
right, but if anyone is interested in helping, I'll gladly take help. (But
it would probably be better to discuss the details in a separate e-mail
thread.)

SBL is a tricky beast anyway. There were some discussions regarding
implementing Chicago Manual of Style a couple of weeks ago. Develelopments on
that front could also be useful for SBL. Don't know what came out of this
though.

Well, the link you provided

February 2021:
https://opensource.adobe.com/dc-acrobat-sdk-docs/acrobatsdk/pdfs/acrobatsdk_jsapiref.pdf
Here is the guide to developers (from the same date):

I get exactly the same results: screen object, but null rendition.
I have no idea what it is needed here.
