Function: c-ts-common--standalone-parent

c-ts-common--standalone-parent is a byte-compiled function defined in c-ts-common.el.gz.

Signature

(c-ts-common--standalone-parent PARENT)

Documentation

Find the first parent that starts on a new line.

Start searching from PARENT, so if PARENT satisfies the condition, it'll be returned. Return the starting position of the parent, return nil if no parent satisfies the condition.

Unlike simple-indent's standalone preset, this function handles method chaining like

    func
    .method() <-- Considered standalone even if there's a "." in
    .method() front of the node.

But ff treesit-simple-indent-standalone-predicate is non-nil, use that for determining standalone line.
