 | |
| 
 | |
| With *command engines* administrators can run engines to integrate arbitrary
 | |
| shell commands.
 | |
| 
 | |
| When creating and enabling a ``command`` engine on a public instance, you must
 | |
| be careful to avoid leaking private data.  The easiest solution is to limit the
 | |
| access by setting ``tokens`` as described in section :ref:`private engines`.
 | |
| 
 | |
| The engine base is flexible.  Only your imagination can limit the power of this
 | |
| engine (and maybe security concerns).  The following options are available:
 | |
| 
 | |
| ``command``:
 | |
|   A comma separated list of the elements of the command.  A special token
 | |
|   ``{{QUERY}}`` tells where to put the search terms of the user. Example:
 | |
| 
 | |
|   .. code:: yaml
 | |
| 
 | |
|      ['ls', '-l', '-h', '{{QUERY}}']
 | |
| 
 | |
| ``delimiter``:
 | |
|   A mapping containing a delimiter ``char`` and the *titles* of each element in
 | |
|   ``keys``.
 | |
| 
 | |
| ``parse_regex``:
 | |
|   A dict containing the regular expressions for each result key.
 | |
| 
 | |
| ``query_type``:
 | |
| 
 | |
|   The expected type of user search terms.  Possible values: ``path`` and
 | |
|   ``enum``.
 | |
| 
 | |
|   ``path``:
 | |
|     Checks if the user provided path is inside the working directory.  If not,
 | |
|     the query is not executed.
 | |
| 
 | |
|   ``enum``:
 | |
|     Is a list of allowed search terms.  If the user submits something which is
 | |
|     not included in the list, the query returns an error.
 | |
| 
 | |
| ``query_enum``:
 | |
|   A list containing allowed search terms if ``query_type`` is set to ``enum``.
 | |
| 
 | |
| ``working_dir``:
 | |
| 
 | |
|   The directory where the command has to be executed.  Default: ``./``
 | |
| 
 | |
| ``result_separator``:
 | |
|   The character that separates results. Default: ``\n``
 | |
| 
 | |
| The example engine below can be used to find files with a specific name in the
 | |
| configured working directory:
 | |
| 
 | |
| .. code:: yaml
 | |
| 
 | |
|   - name: find
 | |
|     engine: command
 | |
|     command: ['find', '.', '-name', '{{QUERY}}']
 | |
|     query_type: path
 | |
|     shortcut: fnd
 | |
|     delimiter:
 | |
|         chars: ' '
 | |
|         keys: ['line']
