[BUG?] WriteKeyValue using relative paths

Post by Nookz »

I have come across something that I don't think is mentioned anywhere in the manual:
Trying to use a relative path in WriteKeyValue seems to always give an 'Illegal path' error in the log.

I've attached a very simple example:
WriteKeyValue_relativePath_.rmskin
Is this a bug or is there something I'm unaware of that would cause this behaviour?

I am not sure this qualifies as a bug or not, but what I can tell you is that any use of the ..\ is getting flagged by Rainmeter as invalid since we restrict the FilePath parameter to the #SKINSPATH# or #SETTINGSPATH# paths. This is to prevent writing to other parts of the OS (even though that can be done other ways).

https://docs.rainmeter.net/manual/bangs/#WriteKeyValue



Typically a relative path starts with the "relative part", like ..\..\SomeFolder\SomeFile.ext. Mixing a relative path within an absolute path (like C:\Users\XXXX\Documents\Rainmeter\Skins\SomeSkin\SubFolder1\..\SomeFile.ext), while perfectly valid in some cases, wasn't really accounted for when implementing this bang.

For now, avoid using ..\ with !WriteKeyValue. I will look into "normalizing" a path before checking for validity, but it may have to wait until Windows 7 is dropped (which is coming sooner rather than later).

For future readers - if any - that may look for a workaround on this that they could use for now:

Of course, while in itself the above has no restrictions on the parent folder one is looking for, using the outcome in a !WriteKeyValue bang will still be subject to limiting the path to be under the Rainmeter's skins or settings path, as noted by Brian above.
