Hi C G,

Thanks for your interest in PlasticSCM :-)

We have this feature already integrated in our latest 5.0 release (5.0.44.533 at the time of writing). :-)

You have two options: using full-featured regular expressions or an extended notation for file paths.

The former requires expressions to be enclosed inside start/end line characters: "^...$". This format allows you to use the standard regular expression syntax.
The latter only allows special strings: "**" (strings of 0+ characters), "*" (string of 0+ non-directory-separator characters) and "?" (a single character, no matter which one). This means that the rest of the rule must use path-valid characters.

For instance, the rule ^/home/user/workspace-one/[0-9][0-9][a-z][a-z]*/.*/.*\.txt$ would match the path /03matchme/doc/new/main.txt inside workspace 'workspace-one', but it wouldn't match neither /001critical/log/error/20140227.txt inside the same workspace, nor anything under a different workspace.

The rule '/main/**/doc*/log.txt' would match /main/dir1/dir2/documentation/log.txt and /main/dir/doc/log.txt, but it wouldn't match /main/dir1/dir2/doc/sublog/log.txt (please note the difference between "**" and "*").

Finally, you can begin each rule with the '!' character to reverse its matches, allowing you to set include/exclude patterns.

We hope this information will answer to any questions you may had, but don't hesitate to contact us if you would like something to be clarified. :-D

Thanks!

Miguel
