= Input: Textarea

OliveTin supports multi-line text inputs, which can be useful for longer messages or scripts. You should set your argument `type` to `raw_string_multiline` to use these.

As the name implies, textareas are raw, and are NOT validated by any regex. For that reason they **cannot** be used with `shell:` — use `exec:` so the value is a separate argv element.

actions:
  - title: Save text to file
    exec:
      - /bin/sh
      - -c
      - echo "$CONTENT" > file
    arguments:
      - type: raw_string_multiline
        name: content
----

In that `exec:` example, `$CONTENT` comes from the process environment (OliveTin exports each argument as an uppercase env var), not from shell-string interpolation of the argument into `shell:`.

This renders like this;
