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 :
* heading L1_12
Hello and welcome, this is a file with self-referencing shell babel source code blocks
...
** heading L2_37
...
#+NAME: block220
#+BEGIN_SRC bash :session sess9
: command 0 ; cd _how-do-I-find-the-dir-of-currently-edited-file_ ; VAR6=`git cmd1` ; VAR7=`git cmd2`
: command 1 ; ssh -o "SetEnv VAR1=machine VAR2=user VAR3=..." targetUser@targetMachine
#+END_SRC
...
#+NAME: block225
#+BEGIN_SRC bash :session sess9
: command 2 ; : do some computation on targetMachine
: command 3 ; echo This code has been launched from emacs process VAR0:_EMACS_SESSION_ID_ \
on computer $VAR1:_SRC_HOSTNAME_ \
run by user $VAR2:_USER_ \
from file $VAR3:_FILENAME_ \
code block named $VAR4:block225 \
in this file positioned under headings: $VAR5:heading L1_12/heading L2_37/ \
which is checked out from $VAR6:_GIT_COMMIT_ID_ \
on branch $VAR7:_GIT_BRANCH_
: command 3 continues ; echo To display the buffer which launched this code on the screen of the running emacs session, run the following command : emacs _What_the_heck_do_I_put_here?_ '&'
#+END_SRC

I guess this is what you mean:

** heading L2_37
#+name: this-block
#+header: :var VAR1=(getenv "HOSTNAME")
#+header: :var VAR2=(message user-login-name)
#+header: :var VAR3=(buffer-file-name)
#+header: :var VAR4=(org-element-property :name (org-element-context))
#+header: :var VAR5=(org-no-properties (org-display-outline-path nil t))
#+header: :var VAR5a=(line-number-at-pos (org-element-property :begin
(org-element-context)))
#+header: :var VAR6=(s-trim (shell-command-to-string "git rev-parse HEAD"))
#+header: :var VAR7=(s-trim (shell-command-to-string "git branch
--show-current"))
#+BEGIN_SRC sh :results raw
echo Run by $VAR2 from $VAR3
echo In a src-block named $VAR4 in $VAR5 at line $VAR5a
echo on commit $VAR6 in git branch $VAR7
#+END_SRC
#+RESULTS: this-block

Dear Mr Kitchin,
you are a genius !!!!!!
A BIG THANK YOU!!!
Wow. I couldn't imagine someone might be able to do this so quickly
and perfectly. Wow.
thank you so much
HJ
PS: Now I'm off to figure out how to invoke emacs to tell it to open up
the window and show this file at the place where this-block block
appears ...

see
https://stackoverflow.com/questions/3139970/open-a-file-at-line-with-filenameline-syntax
there are also ways to make fancier org-links, but I think you will find
what you need in that link.

Not the OP here, but... thanks a bunch!
You just saved me a few hours of hair pulling.
