When <> expands to multiple line and I wrote like this
some-string <<noweb ref>>
then it expands like
some-string line1-from-noweb-ref some-string line2-from-noweb-ref some-string line3-from-noweb-ref
Is there a way to avoid this?

I think you're asking how to prefix only the first line of the noweb block. It will probably depend on the language your using, but I came up with this hack for bash:
#+NAME: example #+BEGIN_SRC text please echo this line date ## but not this one cd test ## this one ls -l ## or this one #+END_SRC Bad source code block, echo prepended to very line: #+BEGIN_SRC bash :noweb yes :results verbatim echo <<example>> #+END_SRC #+RESULTS: : please echo this line : date : cd test : ls -l : Good source code block, echo prepended to the first line only, the rest are executed: #+BEGIN_SRC bash :noweb yes :results verbatim echo \ <<example>> #+END_SRC #+RESULTS: : please echo this line : Thu Nov 9 10:22:32 EST 2017 : total 0 : -rw-r--r-- 1 tws tws 0 Nov 9 09:44 one : -rw-r--r-- 1 tws tws 0 Nov 9 09:44 three : -rw-r--r-- 1 tws tws 0 Nov 9 09:44 two 
- Thank you! Seems like a solution. But why do you think is "The behaviour you describe is normal. " ? For me <<>> looks like usual inline macros. Well, don't you wait that for example in JS
somestring ${nowebref()}do the same - multiply somestring as many as nowebref() will return rows ?Dima Fomin– Dima Fomin2017-11-10 09:26:10 +00:00Commented Nov 10, 2017 at 9:26 - 1I only mean that according to the orgmode manual, the designed behaviour is for some-string to be prepended to each line. I don't have an opinion on whether this is the best behaviour, but it is the intended behaviour of the orgmode authorsTyler– Tyler2017-11-10 18:41:46 +00:00Commented Nov 10, 2017 at 18:41
- Ahh, I see now! I should better RTFM :) By the way, inspired with such behaviour I am trying one trick with <<>> but stuck again. May be you could see with one eye? It's here emacs.stackexchange.com/questions/36832/…Dima Fomin– Dima Fomin2017-11-12 18:44:21 +00:00Commented Nov 12, 2017 at 18:44
some-stringto appear only on the first line? Or not at all? A minimal reproducible example would help clarify this.
