📓 File Triggers and GroundRunners
File Trigger Setup Example
When creating a file trigger, the parameter Directory to watch for file events needs to be set. The input box actively reads the directory structure of the chosen GroundRunner and it is necessary to type each directory in its entirety before moving to the next directory. Once the desired directory path has been created, use the <TAB> key to move to the next field.
File Name Filters are always parsed using RegEx expressions. If the value entered is an exact file name but contains non standard [a-Z, 0-9] characters, they will need to be escaped to ensure proper parsing via RegEx.
Example File Names:
Exact File Name:
Exact File Name with escape characters:
In the following example, a text file is edited and saved. This event invokes the OneCloud File Trigger and the results of the change are subsequently viewed with a List File Content.
