A Note On X Where X = "Emac's Combobulate Package"

Lets inspect combobulate-navigate-previous by step into the function.

The following functions are called in order:

1. combobulate-navigate-previous
2. combobulate--move-point-to-node responsible for display and move node.
3. (combobulate--navigate 'previous) pass previuos to combobulate--navigate
4. combobulate--nav-get-prev-sibling get sibling node by query its parents node and get all of its nodes. sibling nodes are arrange in order, so getting previous or next siblings nodes is easy.
5. combobulate--nav-get-sibling-nodes outputs list of nodes
6. seq filter check for matched node.

Note that getting a node is done by using tree-sitter query. Tree-sitter API provides such query functions.

That’s it.

Peace.
