C++ library to store and filter files with systematic naming conventions using simplified regular expression-like patterns
copied from cf-staging / libfilepatternThe filepattern utility is used to store files that follow a pattern, where the pattern is analogous to a simplified regular expression. The need for filepattern arises in situations where large amounts of data with a systematic naming convention needs to be filtered by patterns in the naming. For example, one may have a directory containing segmented images where the name contains information such as the channel, the column value, and the row value. filepattern provides the ability to extract all images containing such a naming pattern, filter by the row or column value, or group files by one or more of the aforementioned variables.
