texlive-boolexpr - A boolean expression evaluator and a switch command
- Description:
The \boolexpr macro evaluates boolean expressions in a purely
expandable way. \boolexpr{ A \OR B \AND C } expands to 0 if the
logical expression is TRUE. A, B, C may be: - numeric
expressions such as: x=y, x<>y, x>y or x<y; - boolean switches:
\iftrue 0\else 1\fi; - conditionals: \ifcsname
whatsit\endcsname 0\else 1\fi; - another \boolexpr: \boolexpr{
D \OR E \AND F }: \boolexpr may be used with \ifcase:
\ifcase\boolexpr{ A \OR B \AND C } What to do if true \else
What to do if false \fi The \switch command (which is also
expandable) has the form: \switch \case{<boolean expression>}
... \case{<boolean expression>} ... ... \otherwise ...
