NOTE: Although vfs has been meant to be implemented as a separate
|
|
entity redistributable under the LGPL in its current implementation it
|
|
uses GPLed code from src/. So there are two possibilities if you want
|
|
to use vfs:
|
|
|
|
1. Distribute your copy of vfs under the GPL. Then you can freely
|
|
include the GPLed functions from the rest of the mc source code.
|
|
|
|
2. Distribute your copy of vfs under the LGPL. Then you cannot include
|
|
the functions outside the vfs subdirectory. You must then either
|
|
rewrite them or work around them in other ways.

Hi!
|
|
|
|
I'm midnight commander's vfs layer. Before you start hacking me,
|
|
please read this file. I'm integral part of midnight commander, but I
|
|
try to go out and live my life myself as a shared library, too. That
|
|
means that I should try to use as little functions from midnight as
|
|
possible (so I'm tiny, nice and people like me), that I should not
|
|
pollute name space by unnecessary symbols (so I do not crash fellow
|
|
programs) and that I should have a clean interface between myself and
|
|
midnight.
|
|
|
|
Because I'm rather close to midnight, try to:
|
|
|
|
* Keep updating ChangeLog file.
|
|
|
|
* Keep the indentation as the rest of the code. Following could help
|
|
you with your friend emacs:
|
|
|
|
(defun mc-c-mode ()
|
|
"C mode with adjusted defaults for use with the Midnight commander."
|
|
(interactive)
|
|
(c-mode)
|
|
(c-set-style "K&R")
|
|
(setq c-indent-level 4
|
|
c-continued-statement-offset 4
|
|
c-brace-offset 0
|
|
c-argdecl-indent 4
|
|
c-label-offset -4
|
|
c-brace-imaginary-offset 0
|
|
c-continued-brace-offset 0
|
|
c-tab-always-indent nil
|
|
c-basic-offset 4
|
|
tab-width 8
|
|
comment-column 60))
|
|
|
|
(setq auto-mode-alist (cons '(".*/mc/.*\\.[ch]$" . mc-c-mode)
|
|
auto-mode-alist))
|
|
|
|
And because I'm trying to live life on my own as libvfs.so, try to:
|
|
|
|
* Make sure all exported symbols are defined in vfs.h and begin with
|
|
'vfs_'.
|
|
|
|
* Do not make any references from midnight into modules like tar. It
|
|
would probably pollute name space and midnight would depend on concrete
|
|
configuration of libvfs. mc_setctl() and mc_ctl() are your
|
|
friends. (And mine too :-).

PS: If you'd like to use my features in whole operating system, you
|
|
might want to link me to rpc.nfsd. On
|
|
http://atrey.karlin.mff.cuni.cz/~pavel/podfuk/podfuk.html you'll find
|
|
how to do it.
|
|
|
|
PPS: I have a friend, shared library called avfs, which is LD_PRELOAD
|
|
capable. You can reach her at http://www.inf.bme.hu/~mszeredi/avfs.
