Why No Perl Beautifiers up to 1998?
1. Perl's unusually flexible syntax (TMTOWTDI outgrowth) makes accurate parsing difficult- Parsing: breaking down source code into meaningful parts, identifying their functions, and their syntactic relationships
- this is a misconception
-
rudimentary parsing can be good enough for "Basic Beautification"
- e.g., pbeaut can treat File-globs and Input Operators identically
- e.g., <*.txt> vs. <STDIN>
- so it needn't be able to differentiate them!
