Ignore the "separator" for parserCheckboxList.pl and parserRadioButtons.pl in TeX display mode.

[drgrice1]

The default "separator" is a $BR which is defined to be \\leavemode\\\\\\relax if the display mode is TeX. This doesn't work if the CheckboxList or RadioButtons happen to be in a table. Furthermore, the separator doesn't make sense in TeX display mode in any case. So this makes it so that the separator is just not used in the TeX display mode.

This is to address issue #1300.

Should the POD get into this? There's a place where it explains separator but not in a way that clarifies it will only be used in HTML.

Good point. I will add a comment about this.

I just tested this with the following MWE:

DOCUMENT();

loadMacros('PGstandard.pl', 'PGML.pl', 'parserCheckboxList.pl');
$checks = CheckboxList(['A', 'B', 'C'],[0,1]);

BEGIN_PGML
Select A and B

[# [.[_]{$checks} .] #]

END_PGML

ENDDOCUMENT();

and still see errors in the hardcopy. I'm getting a Not allowed in LR mode. error for the \item calls.

I think there's a general latex issue with itemize inside of tabular. There's a suggestion: https://tex.stackexchange.com/questions/150492/how-to-use-itemize-in-table-environment to using the p{} option in the column specifier. I switched the code to that and this did work.

@pstaabp: Yes, to use a CheckboxList in a table you need to use p{}. I don't think there is any way to make niceTables automatically detect that you are putting a CheckboxList into a table cell, so the author will need to add that. You can do this with

DOCUMENT();

loadMacros('PGstandard.pl', 'PGML.pl', 'parserCheckboxList.pl');
$checks = CheckboxList(['First', 'Second', 'Third'], [0, 1]);

BEGIN_PGML
Select First and Third

[# [. [_]{$checks} .] #]*{ align => 'p{2in}' }
END_PGML

ENDDOCUMENT();

The problem also looks quite bad without that in HTML. I changed to "First", "Second", and "Third" to emphasize the point here. This is a screenshot of what you get without the p alignment:
