Description: |
The attached patch adds a "-chan" option to [contents/stat/get/untar/create] (but *not* [add/remove], foor good reasons), which interprets the first argument as a channel name instead of filename. This allows to pass already opened channels, seekable or not. One typical usage is the emulation of 'tar cf - | ...': ::tar::create $pipe $listoffiles -chan Which is typically useful for Wub, to serve content that is to be tarred on-the-fly, instead of (currently) using tempfiles. The same applies on input, where seek is emulated by repeated reads when the channel is not seekable; similarly a "tar tf -" can thus be done on any pipe or socket. Note that the responsibility for 'fconfigure -translation binary' is left to the caller; only raw IO are done on the provided channel, and it is left open on return. I have not included the (needed) documentation update; I would appreciate a hand since I don't have the renderer handy ;-) | |||
