Hello Ken, thank you for your message,
After reading the very interesting get_property function, I found that even though I will probably use it for some cases, it doesn’t apply directly, to my case.
For more examples, if I have 1 source code block:
#+name: greeting #+begin_src sh :var name="world" :results output :session testing
echo "hello, $name\!" #+end_src
I have three options in noweb to use this: - Use its body into another begin_src source code block with <<greeting>> - Use its result “hello, world!” Into another code block, which results in babel trying to execute the hello, command, which doesn’t exist, this with <<greeting()>> - Use its result, the same as above, but with another parameter, results in the same but the variable name is different, so <<greeting(name=“another name”)>>
I’m trying to do the first, but with another parameter, so Use its body into another begin_src source code block with, get the resulting body after changing the variable without it being evaluated, so that I get a valid command to get to bash, like with <<greeting>>, but I can specify a different name variable.
I found the [:body] param but, even though it lets me change the variable as I want, it then tries to evaluate it, so I get a different value but the same hello, command doesn’t exist. Even though what I would want is to get echo “hello, $name\!” but, $name is different.
Thank you for your response Ken, I hope I gave a clearer example with the above.

Hi, I'm not sure that I understand your issue or needs from the provided examples, but I wonder if the example I provide here would be helpful. It bypasses :var an lets you inject a PROPERTY value anywhere. It is also language agnostic. You can use it to execute commands (that are set as PROPERTY values) or set variables to values. https://lists.gnu.org/archive/html/emacs-orgmode/2023-03/msg00251.html -k. On 2023-03-15 at 18:54 -04, suarezmiguelc@icloud.com wrote... Hello Org-mode community. I’m using Emacs Doom Framework, specifically:
Emacs 28.2 (build 1, aarch64-apple-darwin22.3.0, Carbon Version 169 AppKit 2299.4) of 2023-02-23.
I use heavily org-mode for Literate DevOps, so I have a lot of shell commands that connect through SSH and do some things later, for example:
#+name: initSSH #+begin_src shell :var connection=“admin@somehost"
ssh -t miguel@host "sudo -u someuser ssh -t $connection 'sudo su'" #+end_src
So then I can call:
#+call: initSSH(connection=“admin@anotherhost”)
With any other header parameters or session, the above works correctly. I cannot use tramp due to network latency issues, so this is the most performance way for me, since I also have to do some multi-hops which are indeed supported in tramp, but it is too slow for me, so I rather only commands.
The thing is that, I then would like to call these not with a #+call function, but add them into a bigger script, let’s say that I define another command:
#+name: getStorage #+begin_src shell
df #+end_src
Which has to be run in a remote server, could be any remote server as I have to connect to several. So I would like to be able to:
#+begin_src shell <<initSSH(connection=“admin@anotherhost”)>> <<getStorage>> #+end_src
The first doesn’t work as org-mode runs the code and passes the resulting string to bash, which isn’t a command. The latter works normally. So the issue here are the parameters.
So I made another simple example for this:
#+name: greeting #+begin_src sh :var name="world" :results output :session testing
echo "hello, $name\!" #+end_src
#+results: greeting #+begin_src sh
hello, world\! #+end_src
#+begin_src shell <<greeting(name="ss")>> #+end_src
This results in sh: hello,: command not found, as it is executing the function. I see in the documentation that I can: - Call a function’s body with <<namedcodeblock>> - Execute a function and return its results with <<namedcodeblock()>> - Execute a function and return its results even with different params with <<namedcodeblock(param=“sds”)>>
So right now, the one that’s missing is, call a function’s body with different parameters. So the function <<namedcodeblock>> is not evaluated.
After searching a lot, I came across:
#+begin_src shell :session testing <<greeting[:body](name="Testingggg")>> #+end_src
Which results in:
sh-3.2$ PS1="org_babel_sh_prompt> " org_babel_sh_prompt> name='Testingggg' org_babel_sh_prompt> echo "hello, $name\!" hello, Testingggg\! org_babel_sh_prompt> echo 'org_babel_sh_eoe' org_babel_sh_eoe org_babel_sh_prompt> hello, Testingggg\! sh: hello,: command not found org_babel_sh_prompt> echo 'org_babel_sh_eoe' org_babel_sh_eoe org_babel_sh_prompt>
Which is somewhat what I need since at least the variable is changed, but the result of this execution is also passed to shell so, same error.
I can’t find much documentation about this, what is the correct syntax here?,
Thank you!
