Ignition 8.1.21
I have some project with lots of pages and I generate the page-config\config.json file or modify it with an external text editor.
\Ignition\data\projects\MyProjetc\com.inductiveautomation.perspective\page-config\config.json
When I change this file, I need to wait probably this times or restart the gateway services
wrapper.java.additional.1=-Dignition.projects.scanFrequency=100
https://docs.inductiveautomation.com/display/DOC81/Gateway+Configuration+File+Reference
Sometime, probably if somebody has a designer open, the config.json file may be overwritten
@PGriffith I would like to force the system to load my file just after I've write it on disk.

I’m looking for some way to do some git commands without having to stop or restart the server, and only have it scan and use the new files once I have had a chance to validate the g…

any progress about this feature ?
The effort to add a system.project.scan() (and associated SDK-callable mechanism) is on the short-list for one of our teams, which likely means it will be picked up for development early next year.

May's still 'early', right?
8.1.28 will add the system.project.scan method noted above, in the gateway scope. There's also an SDK-accessible requestScan method that returns a CompletableFuture on ProjectManagerBase if you want to do anything interesting from a custom module.
