xparse: Starred commands and IfBooleanTF

0

In some longer redefinition of existing code I am using a construct like

documentclass{book}

usepackage{xparse}





makeatletter

NewDocumentCommand{mymacro}{smO{}m}{

    defblabla{#1}%

    % several lines later in another macro I use

    IfBooleanTF{blabla}{}{}

}



makeatother



begin{document}

    mymacro*{}{}

end{document}

which works fine with texlive 2018 (xparse 2018-10-17) and lualatex.
However, when trying with texlive 2019 (xparse 2019-03-05)

I get the following error

! Undefined control sequence.

<argument> LaTeX3 error:

                Invalid use IfBooleanTF {blabla }

l.15     mymacro*{}{}

What would be the correct way of doing something like this with the new xparse version?

  Why were you saving the argument in a macro in the first place?

  @JosephWright I later redefine another macro where I use blabla. I did not know another way of doing something like this.
