I've been playing around trying to learn MacFuse using the Objective-c api. The LoopbackFS filesystem was good for this, except for me it was still hard to figure out what I needed to implement (when doing my own read/write file system), since the LoopbackFS delegates so much of it's behavior the the standard file system.
Because of this I've been trying to create a generic read/write "InMemory" example. The idea is to create a full read/write filesystem (like LoopbackFS), but do it all in memory in Objective-c code, so that its easy to trace and see exactly what needs to be done to create a generic filesystem that works well through the Finder. I have a first version of this project up and working here: http://github.com/jessegrosjean/macfuseinmemory It seems to work, but I don't really know much about filesystems, so I'm sure there are issues. In particular: - userData is set in readFileAtPath but not in writeFileAtPath even though openFileAtPath and releaseFileAtPath are implemented. I'm not sure if this is my bug, a macfuse bug, or just me misunderstanding what is supposed to happen. - I'm not sure if I'm mapping the read/write methods into the Items fileContents (NSMutableData) correctly. - I'm not dealing with error codes, except for ENOENT. - I'm not sure if I'm missing any cases in [Item itemByResolvingPath:] - When a new symbolic link is created I'm not sure if it's supposed to get any default attributes. - I'm not sure if setAttributes is supposed to replace all existing attributes, or only replaced attribtes specified in the newAttributes dictionary. Thanks for tips and help. Use the code anyway you want. I think it woud be cool if someone who knew what they were doing would review this project, rename/make changes as they wish, and then include it as an example in the MacFuse package. I know that for me at least this sort of example would really help.
