Adding Languages - Simplified
This sections aims to simplify the languages addition, without exposing you the inner workings of neogen, but only showing you the quickest way to add support to a language.
For this, I will do a very quick recap about the backend concepts of Neogen. Pay very attention to this, because i will explain how the defaults are, so you can use the them.
Backend Summary
I will use the lua configuration file here to explain the inner workings of the backend, so feel free to open a new tab and switch to it regularly.
Locator
Concept
The locator is a function responsible of finding the most appropriate parent for annotation purposes
Default Locator
The default locator will fetch the node in current cursor position, and try to go to each parent node recursively until it finds a node name present in parents[<class|func|type>].
Example (with Tree-sitter activated on the side for better comprehension):
The current cursor position is located in the middle of the function (local_variable_declaration).
If I generate a function annotation using neogen, the default locator will try to find the first parent node matchinf one of those:
func = { "function", "local_function", "local_variable_declaration", "field", "variable_declaration" },
which will be variable_declaration. The parent node will now be this node.
