List,
With recent betas, since a fix for tagged elements in tables, underbar
processing seems to have changed (or perhaps I just noticed it after
that fix).
Previously, the following highlight definition worked for both pdf and
export outputs:
\definehighlight [Term][style={{\underbar}}]
With the current betas (2018-10-02 and 2018-10-03) this no longer works
for all output formats. I have tried a few variants, and the results are
as follows:
Using [style={{\underbar}}], the pdf output now shows no underlining,
while the html export has the expected underlining.
Using [style={\underbar}] or [style=\underbar] or [style=underbar], the
pdf output shows the expected underlining, while the html export may
show continuous underlining after the first use, and in any case
eventually loses all formatting. In a large enough document, an error is
generated in the html, but not in the log as far as I can tell:
<div
class="error">...eXt/tex/texmf-context/tex/context/base/mkiv/lxml-tab.lua:1192:
backtrack stack overflow (current limit is 1000)</div>
A test harness:
xxx.css:
highlight[detail="Term"],
div.highlight.Term {
display : inline ;
font-style : inherit ;
font-variant : inherit ;
font-weight : inherit ;
font-family : inherit ;
color : inherit ;
text-decoration : underline ;
}
xxx.tex:
\setupbackend[export=yes]
\setupexport[cssfile=xxx.css]
\definehighlight[Term][style=underbar]% pdf ok, html bad
%\definehighlight[Term][style={{\underbar}}]% pdf bad, html ok
\starttext
\dorecurse{200}{%
\startparagraph
\samplefile{ward}
\Term{pollakis legomenon}
\samplefile{bryson}
\stopparagraph}
\stoptext
The html output of the above shows the text as a single long line and
when displayed the last paragraph are run together with no formatting.
For a larger recurse (250 does it for me) the error described above is
triggered.
As a work-around, I can enable one variant or the other based on the
output mode, but clearly there is an issue here.
