+# Regex
+
+`regex` is a generic plugin to match part of one string in an `input` and extract it into an output.
+
+You provide the name of the value you want to match, and a name to use to add the regex to the output array.
+
+For example, `boavizta-cpu` need `cpu/name` to work, however `cloud-metadata` returns `physical-processor` which usually contains a long string of processors that the instance could be separated by `,`, like so:
+
+```
+Intel® Xeon® Platinum 8272CL,Intel® Xeon® 8171M 2.1 GHz,Intel® Xeon® E5-2673 v4 2.3 GHz,Intel® Xeon® E5-2673 v3 2.4 GHz
+```
+
+## Parameters
+
+### Plugin config
+
+- `parameter` - a parameter by a specific configured string
+- `match` - a regex by which needs to match the `parameter`
+- `output` - output parameter name in the input
+
+### Inputs
+
+- `parameter` - as input parameter, must be available in the input array
+
+## Returns
+
+- `output`: the first match of `parameter` with the parameter name with `match` defined in global config.
+
+## Implementation
+
+To run the plugin, you must first create an instance of `Regex`. Then, you can call `execute()`.
+
+```typescript
+
+const globalConfig = {
+  parameter: 'physical-processor',
+  match: '^[^,]+',
+  output: 'cpu/name',
+};
+const regex = Regex(globalConfig);
+
+const input = [
+  {
+    timestamp: '2021-01-01T00:00:00Z',
+    duration: 3600,
+    'physical-processor':
+      'Intel® Xeon® Platinum 8272CL,Intel® Xeon® 8171M 2.1 GHz,Intel® Xeon® E5-2673 v4 2.3 GHz,Intel® Xeon® E5-2673 v3 2.4 GHz',
+  },
+];
+```
+
+## Example manifest
+
+IF users will typically call the plugin as part of a pipeline defined in a manifest file. In this case, instantiating the plugin is handled by `if` and does not have to be done explicitly by the user. The following is an example manifest that calls `regex`:
+
+```yaml
+name: regex-demo
+description:
+tags:
+initialize:
+  outputs:
+    - yaml
+  plugins:
+    regex:
+      method: Regex
+      path: 'builtin'
+      global-config:
+        parameter: physical-processor
+        match: ^[^,]+
+        output: cpu/name
+tree:
+  children:
+    child:
+      pipeline:
+        - regex
+      config:
+        regex:
+      inputs:
+        - timestamp: 2023-08-06T00:00
+          duration: 3600
+          physical-processor: Intel® Xeon® Platinum 8272CL,Intel® Xeon® 8171M 2.1 GHz,Intel® Xeon® E5-2673 v4 2.3 GHz,Intel® Xeon® E5-2673 v3 2.4 GHz
+```
+
+You can run this example by saving it as `manifests/plugins/regex.yml` and executing the following command from the project root:
+
+```sh
+npm i -g @grnsft/if
+if --manifest manifests/examples/regex.yml --output manifests/outputs/regex.yml
+```
+
+The results will be saved to a new `yaml` file in `manifests/outputs`.
