Does RT_SETTINGS work for ART on Windows?

[lphilpot (Len Philpot)]

Reason I ask is that I’d like to use one of @gaaned92’s Ryzen optimized Windows builds but by default it references a different user folder tree. I can copy the contents over, but using the default path would be much better.

Environment variable RT_SETTINGS [Solved]

I hope this is the right place to post this… According to the documentation, if I create an environment variable by the name of RT_SETTINGS that points to a defined folder, then RawTherapee should use that folder to store a number of files and folders relative to the options, profiles, etc. Interestingly, in my installation, this doesn’t work. Although the environment variable is correctly set, RawTherapee keeps on using the default location for these files. Tried a reboot of the computer, to …

…indicates that path can be overridden with RT_SETTINGS, but so far I’ve been unsuccessful in getting it to work on my Windows 11 computer. The variable is set…

C:\> env
...
RT_SETTINGS=C:\Users\<account>\AppData\Local\ART

…in my local environment. But the optimized build still uses an alternate folder. I’ve set the variable for both my user and system-wide, but to no avail.

Anything else I’m missing?

About the only thing I’ve not tried is rebooting, but since it’s set in my environment and system-wide, that shouldn’t be required (plus I have several other bits of work going on simultaneously )

Thanks.

Try with ART_SETTINGS

[lphilpot (Len Philpot)]

Perfect.

You know, that actually crossed my mind. Dunno why I didn’t try it before asking. One letter made all the difference.

Thanks.

ART_CACHE also works.

[lphilpot (Len Philpot)]

I believe ART_CACHE is used for a different purpose, though. In RawPedia, RT_SETTINGS and RT_CACHE are treated independently.

[gennadiy_4353 (gennadiy)]

ART_CACHE eq. RT_CACHE )

@gennadiy_4353

ART_CACHE eq. RT_CACHE

Yes, but ART_CACHE != ART_SETTINGS just like RT_CACHE != RT_SETTINGS. Cache and settings are different. They could be configured to share the same folder but they’re not for the same purpose.

I would like to know if there are other parameters of this type ART_xxxxxx ?

ART_SETTINGS define the location of the config folder.
Usually, inside the config folder you find the cache folder.
For some reason ( performance for instance) you can want to put this cache folder somewhere else. For that you use ART_CACHE.
I dont think ART use other environment variable.
