- I am reposting this message to let everyone know that I will post a
- summary to this group. Based on the mail messages that were waiting
- for me this morning it appears that many of you are interested.
- I am also giving it wider distribution. Thanks to those of you that
- have sent me mail so far!
-
- The original message follows:
-
- If this is a frequently asked question please forgive me for not
- keeping up with everything posted to this group.
-
- I am interested in opinions and recommendations concerning commercial
- or public domain "smart" diff tools that would make it easier
- to evaluate ASCII test output and reduce test maintenance. Please
- include names, addresses, and phone numbers if you have them.
- Some of the features I would be interested in are:
- - Comparison that disregards portions of the test output that match
- specified patterns (prefer something similar to UNIX regular
- expression syntax). It should be possible to define patterns that
- span multiple lines and are easier to maintain than complex awk
- scripts. Should be able to define patterns that cause only a
- portion of a line to be disregarded.
- - Comparison that disregards portions of the output marked in a file
- containing test output that is known to be correct ("standard"
- comparison file).
- - Tools that will take the output from two or more test runs (known to
- be correct but different) and generate a pattern list and/or a marked
- "standard" comparison file.
- - Display differences in a parallel (side-by-side) format.
- - Ignore white space differences.
- - Source code available.
- - For UNIX systems.
-
- I am aware of `exdiff' by Software Research, Inc. Opinions on this
- system would be appreciated?
