A reasonable solution for the time being would be to check if the righttext argument is empty, and add a final period in the footnote only if it is not (with the assumption being that the user would provide punctuation in any righttext for footnote/endnote citations). I've pushed the following change to the GitHub repo, if you'd like to pull and use it:

```
% 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
  \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
```

This should allow your script to compile, but unfortunately, it doesn't seem to make endnotes work, at least not when I try it. For some reason, the macro \Word{\fastsetup{btx:sbl:cite:inline}} is expanding to nothing inside the \startfootnote ... \stopfootnote environment. I have no idea why this is happening, so any ideas are appreciated.

Joel,

You may not have done anything wrong; this may be an issue with ConTeXt-SBL. In my code for the btx:sbl:cite:footnote setup in publ-imp-sbl.mkvi, I added a comment to this effect:

```
\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...
  \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, unless the righttext ends with punctuation
    \doifendswithpunctelse{\btxparameter{righttext}} {
      \removeunwantedspaces
    } {
      \removeunwantedspaces
      \btxperiod
    }
  \stopfootnote
  \endgroup
  \doifnotinstring{\btxparameter{punct}}{\btxparameter{autopunctuation}}{\btxparameter{punct}}
\stopsetups
```

I define the \btx_sbl_doifendswithpunctelse macro earlier in the module. Initially, when I tried to invoke this macro within the \startfootnote ... \stopfootnote environment (to conditionally add a period at the end of a footnote citation if it does not have a righttext ending with punctuation), I got the same error you got, but for \btx_sbl_doifendswithpunctelse. I wasn't sure why this was happening, so I tried defining a new \doifendswithpunctelse macro. Unfortunately, based on your e-mail, it looks like this doesn't actually fix the problem.

Any help from other developers would be appreciated here! Unfortunately, I don't have a MWE replicating the problem on hand at the moment.

I am using the ConTeXt-SBL package for citations. I need to move my footnotes to the end of each article.

According to the manual, I can suppress the placement of footnotes using two lines of code. I've added these to my minimal working code, placing \setupnote[footnote][location=none] in the header and \placenotes[footnote] where I want the endnotes to appear. It complains this error:

"Undefined control sequence \doifendswithpunctelse"

What did I do wrong?
