Command Line Engines

+ + + +

With command engines administrators can run engines to integrate arbitrary +shell commands.

+
+

Attention

+

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 Private Engines (tokens). The engine base is flexible. Only your +imagination can limit the power of this engine (and maybe security concerns).

+
+

Configuration

+

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:

+
['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.

+
+
+
+
+

Example

+

The example engine below can be used to find files with a specific name in the +configured working directory:

+
- name: find
+  engine: command
+  command: ['find', '.', '-name', '{{QUERY}}']
+  query_type: path
+  shortcut: fnd
+  delimiter:
+      chars: ' '
+      keys: ['line']
+
+
+
+
+
