===== External script =====

==== Adding a new script ====
To configure a new script you need to provide the following information describing the application you want to execute and the parameters passed to it
^ Setting ^ Description ^
|Name| A unique name for the script, used to fetch and distinguish from other scripts|
|Command| The command line to execute, a batch file, cmd or .exe file|
|Arguments| The arguments passed to the script |
|Parameters| A dynamic list of parameters passed to the script by PMA.core|

The following types of parameters are supported
^ Parameter ^ Description^
| Number | A number parameter |
| Path | A path parameter i.e. a slide path |
| String| A string parameter|

==== Parameters & command line arguments ====
The parameters define which query string parameters PMA.core should attempt to parse from the URL when a script is invoked. Then, the values of these parameters can be passed as command line arguments to the script, provided that they also appear in the arguments list contained within the braces. 

Here's an example:
Let's assume we want to invoke a python script and pass it a path and a number argument. We would end up with the following configuration:

^ Option ^ Value ^
| Number | PythonScriptTest |
| Command| python.exe |
| Arguments | d:\scripts\python_test.py -p {slide_path} -n {some_number} -i 123 |
| Parameters | slide_path - type = path, some_number - type = number |

We would invoke this script by crafting the following URL:

<code>http(s)://pma.core.url/scripts/Run?sessionId=your-session-id&name=PythonScriptTest&slide_path=images/collection1/slide1.svs&some_number=10</code>



Then PMA.core would extract and validate the values "images/collection1/slide1.svs" and "10" and pass them on to the command, by replacing {slide_path} and {some_number} respectively. The resulting script looks like this:


''python.exe d:\scripts\python_test.py -p "images/collection1/slide1.svs" -n 10 -i 123''


After successful execution, the complete output of the command invocation is returned to the client.
