RE: Question for areaDetector overlay and file plugin

Hey Jörn,

	> Looking at the implementation reveals that you have to give the filename pattern exactly as shown on the GUI. Otherwise the code will crash.

I was wondering if there are actually other options as the one shown in the GUI and if not: why even try to provide a setting. I assume it was foreseen to be more flexible at some point?

	> If you want to have the date and time included in your filename, the simplest way would be to create your own plugin that overwrites NDPluginFile::openFileBase. This function will be called for each file to be opened. It will call the openFile function of the file plugin (e.g. HDF5File).

Thanks for this hint! I looked at that part of the code trying to understand where and how the file name is exactly constructed and I think maybe the best approach would be to patch  NDPluginFile::attrFileNameSet()?
Here just before this line https://github.com/areaDetector/ADCore/blob/84da95763e24ac2a76b37b99f2276b58afc71e59/ADApp/pluginSrc/NDPluginFile.cpp#L603 
There I could check the content of the prefix looking for the "usual" time syntax ("%x") and replace that?


	> Just adding another button is not fail save! What if you forget to press the button before starting to write? What if you write files in auto increment mode?

Yeah I am aware that this would obviously be bad design and fail in multiple scenarios. Just need to balance this against my basically non-existing c programming experience to come up with a solution 😉
But now of course I hope I will figure out a solution with a local patch to the FilePlugin.

Cheers
