Hello Pavel,
Thanks for the reaction!
...
Looks good, but can you post it as diff -u? No need for tar balls,
diff can create new files, too.
Below are 'diff -u' files for lib/mc.ext.in, vfs/extfs/extfs.ini, and the
actual vfs scripts. The differences are compared with mc-4.6.0-pre2.tar.gz.
I can't put the changes in the CVS repository: the only way I can get on the
Internet is by a Windows machine (I'm not even sure whether I'm allowed to
make any changes).
I have a proposal for future extfs feature:
Would it be a good idea to include a "test" function in every extfs
script?
This way one could open any archive with whatever extension with the same
keystroke (something like Total Commander's Control-PageDown). This would
be useful for e.g. archives that are made executable or disk images with
the extension .img that can have FAT, ext2, or whatever.
Well, you can cd file.exe#uzip...
True, and it works fine but it's not very userfriendly.
Anyhow, here are the diff's:
