----------------------------------
Summary: KAFKA-SHELL: Add character class support to GlobComponent
Key: KAFKA-20189
URL: https://issues.apache.org/jira/browse/KAFKA-20189
Project: Kafka
Issue Type: Improvement
Components: tools
Reporter: Akram Khan
Assignee: Akram Khan
*GlobComponent* currently does not support character classes (e.g. [a-z],
[abc]).
This patch implements character class handling in *toRegularExpression()*
including:
* Support for ranges (e.g. [a-z])
* Support for negation using '!' and '^'
* Support for escaped characters inside the class
* Proper validation of malformed character classes
Malformed character classes continue to fall back to literal behavior,
consistent with existing error handling.
Unit tests are included.
~This change performs minimal validation necessary to ensure safe regex
generation. Full glob syntax validation is outside the scope of this patch.~
