Does xlop support resultstyle when style is set to text. If it does not is there a way to hide the result with style set to text.
\documentclass{article}
\usepackage{xcolor}
\usepackage{xlop}
\usepackage{pstricks}
\begin{document}
\opadd[style=text,resultstyle=\color{white}]{1}{2}
\end{document}
The resultstyle key has no effect in text style. I can offer you a patch to \op@textoperation that does the job in a different way:
\documentclass{article}
\usepackage{xlop}
\usepackage{regexpatch}
\newif\ifshowresult
\newcommand{\showornot}[1]{%
\ifshowresult#1\else\phantom{#1}\fi
}
\makeatletter
\xpatchcmd*{\op@textoperation}{\Op@@r}{\showornot{\Op@@r}}{}{}
\makeatother
\begin{document}
X\opadd[style=text]{1}{2}X
\showresulttrue
X\opadd[style=text]{1}{2}X
\end{document}
The X's are there to show that the space for the result is left.
