[[Source Factoring]] is a general method for separating various orthogonal attributes of source code in order to simplify and clarify manipulation and transformation by handling each attribute independently. In particular, it is one of a number of practical methods for preserving source code formatting attributes such as spacing and commenting across source transformations.
[[Source Factoring]] is the usual method for preserving input formatting and commenting characteristics when using [[http://www.program-transformation.org/Transform/TXL][TXL]]. Use of source factoring with TXL is described in the paper:
