Re: Noweb Function's body without evaluation

[suarezmiguelc]

Wow, works!, thank you very much.

Now, I have a more specific example.

#+name: initSSH
#+begin_src shell :var connection=“admin@10.0.3.200" :noweb yes
ssh -t miguel@172.28.3.249 "sudo -u admin ssh -t $connection 'sudo su'"
#+end_src

#+name: getClientInstanceNameNew
#+begin_src shell :session something :var connection="admin@10.0.3.149" :var 
client="example_client" :var apacheDir="/etc/apache/vhosts"
<>
client=$client
apacheDir=$apacheDir
grep $client $apacheDir/*
#+end_src

So, the initSSH call works successfully, so that concludes my first question, 
being that I can now affect the $connection variable. Thank you again!

However, since the SSH call changes the environment, the $client and $apacheDir 
variables are not defined in the new environment. I did try setting it again 
like above, but this doesn’t help as the variables do not exist.

 99% of the commands I run are remote so, I will keep investigating this. It 
would make more sense to use :dir and tramp, but as the connections are slow, I 
can only connect with this call which works pretty fast.

Babel zip after exporting file

[suarezmiguelc]

Hello Emacs org-mode community, I’m trying this example:

** index.js
:PROPERTIES:
:header-args: :tangle index.js :post-tangle (shell-command-to-string "zip 
index.js.zip index.js && rm index.js")
:END:

First endpoint example:

#+begin_src js
exports.handler = async (event, context) => {
  console.log('Received event:', JSON.stringify(event, null, 2));
  return {
statusCode: 200,
headers: {
  'Content-Type': 'application/json'
},
body: JSON.stringify({
  message: 'Hello, world!'
})
  };
};
#+end_src

What I want is to:
1. Tangle the index.js file
2. Zip it as index.js.zip
3. Delete the raw code index.js

The thing is that, the command inserted in :post-tangle is executed before the 
creation of the file, so it only works if the file already exists, so:
- First run, file doesn’t exist, only index.js is generated.
- Second run, zip file appears, index.js is intact since the rm index.js 
command ran but then index.js was generated again.

How should I debug this?

Re: Noweb Function's body without evaluation

[suarezmiguelc]

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 <>
- 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 
<>
- Use its result, the same as above, but with another parameter, results in the 
same but the variable name is different, so <>

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 <>, 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.

Noweb Function's body without evaluation

[suarezmiguelc]

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
<>
<>
#+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
<>
#+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 <>
- Execute a function and return its results with <>
- Execute a function and return its results even with different params with 
<>

So right now, the one that’s missing is, call a function’s body with different 
parameters. So the function <> is not evaluated.

After searching a lot, I came across:

#+begin_src shell :session testing
<>
#+end_src

Which results in:

sh-3.2$ PS1="org_babel_sh_prompt> "
org_babel_sh_prompt> name='Testin'
org_babel_sh_prompt> echo "hello, $name\!"
hello, Testin\!
org_babel_sh_prompt> echo 'org_babel_sh_eoe'
org_babel_sh_eoe
org_babel_sh_prompt> hello, Testin\!
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!
