TclVFS is the extension that exposes the core level Virtual File System
(VFS) layer, now part of Tcl/Tk (8.4a5 is required, 8.4.1.1 or newer for best possible operation, using Tcl 8.4.3 or 8.4.4 would be a good idea.).  The current version of the tclvfs extension is 1.3.0

Take a look at the [One-line web browser in Tcl] using [TclVFS].

----
See also [VFS].  The C extension is now very robust and well tested.
But, distributed with tclvfs are a large number of virtual filesystem
implementations (in pure Tcl).  Many of these still need a lot of work
(but since it is pure Tcl, lots of people should be able to help).

tclvfs relies on [Memchan] or some equivalent to 'open' (or 'load' or 'source') any file. 

'''Please help develop the tclvfs package further!'''

Contributions of binary versions of tclvfs to be placed on sourceforge much appreciated.

TclVFS needs to be stress tested, QA'd and put into either the core, or a standard [Tcl Binlib] ... it's far too useful and fundamental for it to be kept as an optional extension.

'''Questions, Problems'''

Can tcl and tclvfs together be used to poke around a starkit?

''Don't understand the question.  Yes, would be my answer, mount the starkit via vfs::mk4 ... -[jcw]''

04feb05 [jcw] - Would it be an idea to map an arbitrary X(HT)ML tree to VFS?

[LV] So the results would be the ability to navigate an XML tree as if the nodes
were directories and the actual items would be files?  Sounds intriguing.  How would
the attributes be represented?

----
I think a very nice vfs would be an LDAP vfs using the tcllib ldap package to present a DIT as a filesystem. (and entries probably as LDIF formatted files)
