How do I use tables as entries?

[kentookura]

I have a command that returns a blob of json whicjh I am parsing into a lua table that Iwould like to pass into fzf.
The prototypical item looks something like this:

{
  route = "ex-0002.xml",                                                                                                    
  sourcePath = "/home/user/forest/trees/ex-0002.tree",                                                                     
  tags = {},                                                                                                                 
  taxon = vim.NIL,                                                                                                           
  title = "example"
}

I would like the entry to display both the title and the route, but open the file in vim upon selection.
If I pass in the entire table to the fzf callback, it just displays a bunch of lines like

table:0x......

If I pass in the title, it displays correctly, but how can I then use the sourcePath field when the item is selected?

Thanks!

See https://github.com/ibhagwan/fzf-lua/wiki, you can’t pass a table in the ways that you described (json key-value), to pass the data into fzf_exec you’ll need to convert the data into a list of strings (using string.format), I.e:

{ 
  “Line1”,
  “Line2”,
}

if you need access to metadata you’ll need to store it separately and have the line contain an index number (or any other identifier) so you can access the metadata, alternatively you can put the metadata into the line and hide it using --with-nth (read man fzf).
