^\s*at\s+([\w$.]+)\(([^)]+)\)$ (flags: gm)JavaScript / ECMAScript code
jsJavaScript
const re = new RegExp("^\\s*at\\s+([\\w$.]+)\\(([^)]+)\\)$", "gm");
const input = "\tat com.example.MyClass.method(MyClass.java:42)";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).
How the pattern works
`^\s*at\s+` matches the indent and 'at' keyword. `([\w$.]+)` captures the fully-qualified method. `\(([^)]+)\)$` captures the source location.
