result of code evaluation

result of code evaluation

[Henri-Paul Indiogine]

Greetings!

I am just now starting to use babel in my org-mode files.  I am
intrigued by its capabilities, but I encountered a strange phenomenon:

--------8<------------------------------->8-------------
#+srcname: test
#+begin_src sh :results value
#!/bin/bash

echo "hello"

#+end_src

#+results: test
: hello
-------8<--------------------------------->8------------

Why is there a ":" at the beginning of the results line?  Can I get rid of it?

Thanks,
Henri-Paul

Its purpose is to delimit the result block. Imagine you re-eval the code
block, and that (by default, BTW) the result block must be overridden by the
new value, Babel must have a way to identify what to delete first.

The only other solutions are:

- use the option =:results raw=, but you can't do any replace anymore (of old
  results by new results)

- =(setq org-babel-min-lines-for-block-output 1)=, to force Org to put the
  output enclosed in a #+begin/end_example block.

Best regards,

I dont know, but the example on
http://orgmode.org/guide/Working-With-Source-Code.html also includes a
':' at the beginning of the line.

I like the second option.   I have place the line in my .emacs and it
works beautifully.

Thanks!

I did it with (setq ... 2), so that only one-line results get prefixed by a
colon. All the others are enclosed in a block.

You're welcome. Glad to help.

Greetings!

I have another question regarding the output of the bash script.   I
have a bunch of echo statements.  org-mode outputs now everything in a
table.  Is it possible to suppress this and have just plain lines?
That was the behavior with a simple script.

Thanks,
Henri-Paul

Yes, the ":results scalar" header argument is what you want.

#+begin_src sh :results scalar
  echo 1
  echo 2
  echo 3
#+end_src

#+results:
: 1
: 2
: 3
