AWS EventBridge Scheduling Expressions

Flavor
·
Java
This validates AWS EventBridge scheduling expressions using the rate() and cron() formats. It may not catch all invalid expressions, but it should properly validate all valid expressions, as demonstrated in the unit tests. Please let me know if I missed any valid expressions. Originally attempted this using named capture groups and named back-references to reduce duplication. Unfortunately, named capture support is tricky, so they were all converted to duplicated non-capturing groups instead.

Extract text strings from repeating text fields followed by a suffix

Java
This regex expression is useful for extracting only the text string from a value in a column that may contain values from individual rows with repeat strings tagged with a suffix. For example - Row 1: "Sales (#1)", Row 2: "Sales Match (#2)". From the shared examples, this regex will extract the text "Sales" and "Sales Match."
