How can we help you?

I want to display the title of the file displayed by the buffer as the winbar text. Is there a way to grab the title of the file from zk-nvim? I notice telescope grabs it from the notes.title in its entry_maker but it seems like this table is obtained from the LSP via something like zk list, which means it wouldn't be suitable for this use.

You can try this in lua:

require('zk.api').list(
  nil,
  { hrefs = { vim.fn.expand('%') }, select = {"title"} },
  function(err, res)
    print(res[1]["title"])
  end
)

Or if you want to use an ex command, go straight to the CLI tool:

!zk list % -q --format {{title}}

Thanks for the reply, for the Lua script, as I understand it the zk-nvim implementation of zk.list does not actually return the value, rather it runs a callback function on it. (I don't actually want the value printed, I need to store it as a variable to be used elsewhere). Is it possible to return the value?

In the meantime something like vim.b works to store the value in the buffer (although this still has limitations):

title = require('zk.api').list(
  nil,
  { hrefs = { vim.fn.expand('%') }, select = {"title"} },
  function(err, res)
    vim.b.title = res[1]["title"]
  end
)

Yes this API is asynchronous, there's no way to run it synchronously as the native Lua LSP client is asynchronous.

If you really need it synchronous, I would resort to using the CLI tool directly. But ideally you would just update the winbar asynchronously.
