DESCRIPTION
Runs Algorithm::Diff against two functions to make writing macros easier.
OPTIONAL EXPORTS
- fmt_optree_diff( \&code_a, \&code_b, ... )
-
This is like optree_diff except that it returns a list of nicely formatted text descriptions of the changes to the optree.
- optree_diff( \&code_a, \&code_b, ... )
-
A wrapped call to Algorithm::Diff::diff(). fmt_optree_diff uses this as input.
- optree_sdiff( \&code_a, \&code_b, ... )
-
Algorithm::Diff::sdiff( ... )
- optree_traverse_sequences( \&code_a, \&code_b, ... )
-
Algorithm::Diff::traverse_sequences( ... )
- optree_traverse_balanced( \&code_a, \&code_b, ... )
-
Algorithm::Diff::traverse_balanced( ... )
CAVEATs
This module is still under development. While the code works mostly correctly, the test 3-and-or.t expresses a wish that redundant information not be included in the output. This module will change in small ways until I can get the output looking proper.

B::Keywords supplies seven arrays of keywords: @Scalars, @Arrays, @Hashes, @Filehandles, @Symbols, @Functions and @Barewords. The @Symbols array includes the contents of each of @Scalars, @Arrays, @Hashes and @Filehandles. Similarly, @Barewords adds a few non-function keywords (like __DATA__, NULL) to the @Functions array.
All additions and modifications are welcome.
