Dan Davison 2056d7d419 babel: Allow shell-command-on-region to execute remotely ... These changes solve two problems: both are discussed in the following thread http://lists.gnu.org/archive/html/tramp-devel/2010-02/msg00025.html of which a summary follows. Firstly, shell-command-on-region does not work with tramp in the same way that shell-command does. I.e. whereas (let ((default-directory "/user@remote-host:")) (shell-command "hostname" t)) gives the remote hostname, (let ((default-directory "/user@remote-host:")) (shell-command-on-region (point) (mark) "hostname" t)) does not. The reason is that shell-command-on-region calls call-process-region, which does not use a tramp handler for remote files. However, such a file handler does exist (unused) in the tramp sources: tramp-handle-call-process-region. There is a slight problem in that there is a bug in that function definition in current tramp (which has persisted because the function is not normally used). Therefore, we define an org-babel version of tramp-handle-call-process-region which fixes the bug, and we bind call-process-region to org-babel-tramp-handle-call-process-region for the duration of org-babel-execute-src-block.		2010-02-27 14:14:08 -05:00
