dsh-regex

The most frustrating part of regex work is often not crafting the pattern itself, but repeatedly wanting to see where it matches and how groups split without leaving your editor context. dsh-regex brings validation right into the conversation: no browser tab, no temporary dev server. Tweak the expression, see match positions and captured groups immediately, and keep iterating without losing momentum.

Built with pure Node and no extra runtime dependencies, the plugin registers three tools. regex_test displays match positions and capture groups so you can confirm exact expression behavior. regex_replace performs substitution with safe handling of special characters, preventing escape sequences from being misread as literals. regex_escape sanitizes user-supplied strings by escaping all regex metacharacters in one step, making it safe to splice them into larger patterns.

Ideal for developers who regularly sanitize user input, build text-template replacement logic, or debug complex regex and want a fast feedback loop. No additional toolchain required; once installed, the tools are callable directly in-session.
