Message-ID: <a140aec2-a5a2-d137-ef0c-5d3eabcb0081@XXXXXXXXX.XXX> (raw)
hi,
I'm trying to figure out how to write a block , header, PROPERTY or
whatever is necessary so the output of a command in babel source block
identifies it own position - the line (or block or something) in buffer
(or at least the file) in which it is written. ( Plus the checked out
git revision / branch. )
I've been experimenting with the following, so far without much luck ...
Which of these pieces of information (see the "echo" line below) is it
possible to get? Which is easy? (variables VAR[0345] are most critical)
How would one write a snippet which provides (some of) this information?
Is it much harder with command 1 being SSH to a remote machine? Would
":dir user@remotemachine:/some/dir" work better? Or at all?
Perhaps I would know how to find out VAR6 and VAR7 by running first
some `git cmd1` and `git cmd2` locally in a " command 0 " - but is there
a way to get that info from magit somehow?
But what I am most desperate for is how to cause orgmode block to set
VAR0, VAR3, VAR4 and VAR5, and - also fairly important - how to use the
combination of VAR[0345] do open / recall the file onto the screen
Thanks a million for helping me out here ...
HJ
This is the sample file :
