Thanks. This is the tree produced by tree-sitter, does it match your
expectation?
(heredoc_body
(simple_expansion $ (variable_name))
(command_substitution $(
(command
name: (command_name (word))
argument: (word))
))
(simple_expansion $ (variable_name)))
treesit-node-at gives you the _smallest_ node at point, maybe that’s why
you didn’t see expected behavior?
