Regex Match (`regexMatchNode`)

Category: Data & Text

Intended behavior

Tests text against a regular expression, returning whether it matched and the first match.

Inputs

ID	Label	Type	Unwired default
`text`	Text	string	""
`pattern`	Pattern	string	"\d+"
`enabled`	Enabled	boolean	true

Outputs

ID	Label	Type	Default
`matched`	Matched	boolean	undefined
`match`	First Match	string	undefined

Configuration defaults

{
  "ignoreCase": false
}

Observed frontend behavior

This calls the production passive computation with the declared input/config defaults. Cached state, trigger execution and project wiring are separate.

{
  "kind": "passive-default-probe",
  "outputs": {
    "matched": false,
    "match": ""
  }
}

Observed backend behavior

Offline production passive computation with the same declared defaults; no device or model service is invoked.

{
  "kind": "passive-default-probe",
  "outputs": {
    "matched": false,
    "match": ""
  }
}

Current frontend implementation

Extracted production branches; helper calls and project execution context are defined in the referenced modules.

src/lib/extra-node-compute.ts:132

regexMatchNode: (inputs, config) => {
    try {
      const re = new RegExp(String(inputs.pattern ?? ""), config.ignoreCase ? "i" : "");
      const m = re.exec(toStr(inputs.text));
      return { matched: m !== null, match: m ? m[0] : "" };
    } catch {
      // An invalid pattern is a user typo mid-edit, not a graph failure.
      return { matched: false, match: "" };
    }
  }

Verification limits

Default passive probe is an observation, not proof of all configurations, trigger behavior, or correctness. See ../NODE_RUNTIME_AUDIT.md and ../AUDIT_VALIDATION.md for test evidence.
Enabled=false uses the runtime bypass mapping; bypass output can differ from the normal declared output type.
