Not filter string node without closing delimiter in lua

Tree-sitter
1

I want to filter string nodes using treesitter like this:
bar 'foo' 2 > bar 2
But when the closing delimiter is not present then don’t filter.
bar 'foo > bar 'foo
This works fine in other languages, like python, but in lua, it treats a non-closed delimiter as a string
bar 'foo > bar (in lua)
Are there any ways to not have this behavior or do I need to write a special case for lua?

That’s just the way the Lua grammar implementation works. Let’s take a sample. Here is a test buffer:

bar 'foo'
bar 'foo

We can now loot at the tree:

function_call [0, 0] - [0, 9]
  name: identifier [0, 0] - [0, 3]
  arguments: arguments [0, 4] - [0, 9]
    string [0, 4] - [0, 9]
      start: "string_start" [0, 4] - [0, 5]
      content: "string_content" [0, 5] - [0, 8]
      end: "string_end" [0, 8] - [0, 9]
function_call [1, 0] - [1, 8]
  name: identifier [1, 0] - [1, 3]
  arguments: arguments [1, 4] - [1, 8]
    string [1, 4] - [1, 8]
      start: "string_start" [1, 4] - [1, 5]
      content: "string_content" [1, 5] - [1, 8]
      end: "string_end" [1, 8] - [1, 8]

As you can see the grammar has recognized 'foo as a string, and as far as far as Neovim is concerned that’s a string node. However, note the anonymous node string_end: it has length zero, so you could define a predicate and add it to your query so the string node only matches if the string_end child has a non-zero length.

See :h treesitter-predicates for details. You can use either an existing predicate like match? or define your own.
