Parse, Analyze and Manipulate Perl (without perl) The ability to read, and manipulate Perl (the language) programmatically other than with perl (the application) was one that caused difficulty for a long time. The cause of this problem was Perl's complex and dynamic grammar. Although there is ... [More] typically not a huge diversity in the grammar of most Perl code, certain issues cause large problems when it comes to parsing. Indeed, quite early in Perl's history Tom Christenson introduced the Perl community to the quote "Nothing but perl can parse Perl", or as it is more often stated now as a truism: "Only perl can parse Perl" PPI tries to solve this problem.

graylex

Compare

  Analyzed about 20 hours ago

graylex offers a means to do string operations on input streams without slurping all input at once by using Common Lisp Gray Streams, fixed-sized and flexible buffers. This is especially interesting for lexical analysis ("lexing") where input files can be exuberant, e.g. SQL dumps weighing hundreds of Megabytes.
