Is tangling files possible?

[ghost]

Is it possible to export the code segments of a .org file to its own file? For example, can I export Python snippets throughout a file called README.org to a file called config.py?
Update: I found a Python script called org-babel-tangle.py that does tangling from the command line so I don't need to use Emacs. I'm still wondering if there's any way to implement it as a Neovim plugin, though.

I'm looking for the same thing (but for lua)!
I could also write a plugin to do this, but I don't want to reinvent the wheel if not necessary 🙂
In that case, what would be the best syntax for it that is supported by treesitter? I'm asking for opinions of course, nothing too deep. I was thinking of using a :TANGLE: property under the headings, but for the whole document it doesn't look like it could work (as it doesn't work the original #+property: header-args :tangle [file] by the way)

You can create a user command that calls that script on the current file. Here's an example.

vim.api.nvim_create_user_command('OrgTangle', function()
  local cmd = string.format('terminal org-babel-tangle.py %s', vim.fn.expand('%'))
  vim.cmd(cmd)
end, {buffer = true})

Great function. Using it :-)

This is cool. I tried it, and it works. Thank you for posting this :-)

P.S.
May I suggest please that this functionality should be made part of the plugin?

After some playing with org-babel-tangle.py, I see that you need to repeat this :tangle /path/to/file for every #+BEGIN_SRC block. Tedious. Bummer.

Yes. I am looking at it now. Thank you very much :-)

@andreadev-it feel free to open up a PR for that, if you want ;) tangling is part of Emacs orgmode and should therefore be part of this repo as well 👍

[andreadev-it]

Hi @jgollenz ,
Currently, my code does not reflect perfectly the way that org mode handle this situation on emacs, since it seems that some of those options are not supported by treesitter (or at least were not supported when I last checked). Do you believe it's still doable to implement this, or would it be better to wait (or work) and get a full implementation of the original syntax?

[jgollenz]

In general, this project tries to be a faithful port where possible. However, in my opinion, supporting a feature like this partly (ideally with a plan how to support it fully in the future) is better than not supporting it at all. Please open up a draft PR so we can discuss the issues in detail 👍

[andreadev-it]

@jgollenz Done, both for this and for the multipurpose enter key discussion 🙂
