The package provides commands for “splitting” a token list at the first occurrence of another (specified) token list. I.e., for given token lists s, t return b and the shortest a, such that t = a s b. The package’s mechanism differs from those of packages providing similar features, in the following ways: – the method uses TeX’s mechanism of reading delimited macro parameters; – the splitting macros work by pure expansion, without assignments; – the operation is carried out in a single macro call. A variant of the operation is provided, that retains outer braces.
