dfuse 0.3.0 - D Language bindings for Fuse
Hi,

We are happy to announce the release of 'dfuse', a high level D 
language binding
for fuse (http://fuse.sourceforge.net). It supports libfuse >= 
2.8 and works on
both Linux and MacOS (osxfuse). You can find the project at:

    https://github.com/facebook/dfuse

We at Facebook have been working on dfuse for the last weeks and 
are actively
using it in production. While the interface is still limited, we 
hope to work
towards a full featured fuse binding.

If you want to get involved, feel free to sent pull requests, 
submit issues and
direct any questions about dfuse to the D mailinglist or ping 
'dsop' on IRC.

Awesome. Thank you and the guys at Facebook for writing this. I 
was working on my own fuse bindings so I could try writing my own 
adb filesystem for fun, but now this is out I'll just use this 
and submit bug reports or pull requests when I notice any issues.

Awesome!

Will this be added to code.dlang.org?
There's a question on reddit regarding performance. I'd guess
performance should be quite good in general, but the simple example
throws/allocates* Exceptions on missing files. Does this perform well
enough?

* I guess in this case you could 'cache' the exception in a
 global variable, but druntime still allocates the stack trace (only
 once though). Druntime uses some tricks to avoid these allocations
 for OutOfMemory errors and this trick should probably work for dfuse
 as well, but I still wonder if it isn't easier to simply return a
 result code from getattr and readdir.

Funnily, a FUSE bindings package was added just some days ago:
http://code.dlang.org/packages/fuse

Initially, I thought that would be the same package, but it's not.

Hi Johannes,

the choice of using throw for exception was mostly to follow the 
python-fuse bindings which we initially used for a prototype. I 
agree that we could instead return a value for performance 
considerations. However there is a balance of how many errors you 
expect and, as far as I am concerned, the more convenient way of 
reporting errors using exceptions up the callstack.

Interesting. When we started with dfuse the mentioned fuse 
library was in a not good enough state. Still while it seems to 
offer all the functionality of the high level fuse API, it 
doesn't do conversions to D types such as const(char)[] and still 
passes around pointers. My overall goal is to use D's types and 
strength to make an easier interface.
