Sorry, these are definitely errors on my part. The first one ("invalid
parent sbl:list:title:unpublished for sbl:list:title:thesis,
sbl:list:title:unpublished defined too") was thankfully an easy fix; I just
had to move \definebtx[sbl:\s!list:title:unpublished] before
\definebtx[sbl:\s!list:title:thesis]. I've now pushed this change to the
repo at https://github.com/jjmccollum/context-sbl.
The second error ("Undefined control sequence \currentbtxloctext") is
unfortunately more puzzling. In an effort to preserve backward
compatibility with biblatex usage, I focused on implementing citations in
the SBL style using \autocite, \inlinecite, \parencite, and \footcite
commands, and I neglected to see if the ConTeXt \cite command would work as
expected.
The \currentbtxloctext macro is used for handling more complicated
situations regarding volume, part, page number, etc. citations; for the
purposes of your MWE (and for most citations) a righttext with the page
number citation should also work just fine, so the lack of a loctext
parameter in the \cite command shouldn't be a problem. The
\currentbtxloctext macro is defined in most of the btx:sbl:cite setups in
publ-imp-sbl.mkvi, always via the command
```
\def\currentbtxloctext{\btxparameter{loctext}}
```
The default value of this parameter and similar ones should be \empty, per
the \definebtx[sbl] command in publ-imp-sbl.mkvi:
```
\definebtx
[sbl]
[
...
lefttext=\empty, % empty by default
altloctext=\empty, %empty by default
loctext=\empty, %empty by default
righttext=\empty, % empty by default
punct=\empty, % trailing punctuation (empty by default)
...
]
```
If I've coded this correctly, then the loctext parameter should default to
\empty when you do not specify it for your \cite command. This seems to be
the case when you first invoke the \cite command (i.e., in the
btx:sbl:cite:footnote setup).
Here is the problem: if you invoke the btx:sbl:cite:inline setup from
inside the btx:sbl:cite:footnote setup, it seems that the loctext parameter
is no longer accessible, and thus, it does not get defined. If I patch the
btx:sbl:cite:footnote setup as follows, then I no longer get the "Undefined
control sequence \currentbtxloctext" error:
```
% Inline footnote citation setup (with intelligent trailing punctuation
replacement)
\startsetups btx:sbl:cite:footnote
\removeunwantedspaces
\doifinstring{\btxparameter{punct}}{\btxparameter{autopunctuation}}{\btxparameter{punct}}
\begingroup
\letbtxparameter{punct}\empty % don't pass the trailing punctuation down
to the inline setup
\let\doifendswithpunctelse\btx_sbl_doifendswithpunctelse % why is this
necessary? For some reason, \btx_sbl_doifendswithpunctelse is not
recognized within the footnote environment...
\def\currentbtxcitealternative{footnote}
\def\currentbtxcategory{\btxfield{category}}
\def\currentbtxloctext{\btxparameter{loctext}}
\def\currentbtxaltloctext{\btxparameter{altloctext}}
\startfootnote
\Word{\fastsetup{btx:sbl:cite:inline}}% capitalize the first word in
the footnote (needed to render "Ibid." and "Idem" correctly)
% Add a closing period if there is no righttext
\doif{\btxparameter{righttext}}{\empty} {
\btxperiod
}
\stopfootnote
\endgroup
\doifnotinstring{\btxparameter{punct}}{\btxparameter{autopunctuation}}{\btxparameter{punct}}
\stopsetups
```
But I still get errors involving other macros that now appear to be
undefined—specifically, the \btxsblshorthandbeforeloctext macro (and,
likely, the \btxsblvolumebeforeloctext macro, as well). These are initially
defined as "no" in the SBL style module outside of the various citation
alternative setups, but they are conditionally redefined as "yes" in these
setups based on specific information in the bibliographic entry.
This pattern suggests a bigger problem. Do these variables and the \cite
parameters fall out of scope when we enter a footnote environment inside a
setup? In my code, I noticed that a macro defined outside of the
btx:sbl:cite:footnote setup was unrecognized within the footnote
environment unless I freshly redefined it:
```
\let\doifendswithpunctelse\btx_sbl_doifendswithpunctelse % why is this
necessary? For some reason, \btx_sbl_doifendswithpunctelse is not
recognized within the footnote environment...
```
Meanwhile, if I change the default citation alternative to "inline" or
"paren", then everything works:
```
\usebtxdataset[default][references.bib]
\setupbtx[dataset=default]
\usebtxdefinitions[sbl]
\setupbtx[sbl:cite][alternative=paren] % or alternative=inline
\setupinteraction[state=start]
\starttext
superior typographic output \cite[lefttext={e.g.}][taraborelli:beauty].
Therefore, the {\TEX}book mentions that the word
\quotation{shel\noligature{ff}ul} should indeed be rendered without the
ff-ligature \cite[righttext={p.~19}][knuth:texbook].
\placelistofpublications%[numbering=yes]
\stoptext
```
I realize that the above "fix" does not truly solve the p
