package. Summary description: split list at list inside in TeX's mouth License type: lppl Announcement text: ---------------------------------------------------------------------- `bitelist.sty' provides commands for "splitting" a token list at the first occurrence of a contained token list. I.e., for given token lists s, t return b and shortest a, such that t = a s b. As opposed to other packages providing similar features, (i) the method uses TeX's mechanism of reading delimited macro parameters; (ii) the splitting macros work by pure expansion, without assignments, provided the macro doing the search has been defined before processing (e.g., a file); (iii) instead of using one macro for a "substring" test and another one to replace the "substring"--which includes extracting corresponding prefix and suffix--, the *same* macro that detects the occurrence returns the split; (iv) e-TeX is not required. (And LaTeX is not required.) This improves `fifinddo.sty' (v0.51). An elaborated approach (additionally to a simpler one) is provided that does not loose outer braces of prefix/suffix. "Substring" detection and "string" replacement are (implicitly) included with respect to certain representations of characters by tokens. Counting occurrences and "global" replacement could be achieved by applying the operation to earlier results, etc.--so this approach seems to be "fundamental" for a certain larger set of list analysis tasks. The documentation aims to prove the correctness of the methods with mathematical rigour.
