Thank you, but whitespace is ignored in .bib file syntax. To prove that whitespace handling isn’t the bug, just try accessing it:

\startluacode
local current = publications.datasets.default
tex.print('\\starttyping')
tex.print(table.serialize(current.luadata))
-- to show that the key doesn’t contain weird invisible characters, I’ll type it here:
tex.print(table.serialize(current.luadata.angerer2016))
tex.print('\\stoptyping')
\stopluacode

will display:

t={
  ["angerer2016"]={
    ["author"]="Angerer...",
    ["category"]="article",
    ...
  },
}
t={
  ["author"]="Angerer...",
  ["category"]="article",
  ...
}

Another thing: Uncommenting the \placelistofpublications makes it work, but not in my real document. I didn’t go through the trouble of reproducing when that stops working, as I think the root cause can probably be found with my minimal example.

Best, Phil

Don't know if that's related, but you should probably removethe space before the key in your bibfile.

Betreff: [NTG-context] Bib support broken in lmtx

Hi! A pretty minimal document using a bibliography is broken for me:

test.lmtx:
\enableregime[utf-8]
\mainlanguage[en]

\usebtxdataset[default][test.bib]
\setupbtx[dataset=default]
\usebtxdefinitions[apa]

\starttext

\cite[authoryear][angerer2016]

%\placelistofpublications[default][method=dataset]

\stoptext

test.bib:
@Article{ angerer2016,
author = {Angerer, Philipp and Haghverdi, Laleh and B{\"{u}}ttner, Maren and Theis, Fabian J and Marr, Carsten and Buettner, Florian},
doi = {10.1093/bioinformatics/btv715},
issn = {14602059},
journal = {Bioinformatics},
language = {en},
number = {8},
pages = {1241--1243},
title = {{Destiny: Diffusion maps for large-scale single-cell data in R}},
url = {http://bioinformatics.oxfordjournals.org/lookup/doi/10.1093/bioinformatics/btv715 files/103/Angerer et al. - 2016 - destiny diffusion maps for large-scale single-cel.pdf},
volume = {32},
year = {2016}
}
