How pattern works
- Create a literal string pattern.
- Pattern objects are accepted by matches, contains, startsWith, endsWith, erase, replace, and the boundary helpers added in this compatibility group.
- Literal pattern text is escaped before matching.
Example
Using pattern with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how pattern changes the result.
Run a small pattern example, explain the result, then change one input and compare the output.
