mini.ai How to setup around/inside for class constructors?

[yavorski]

Hi,

Is it possible to configure the around / inside objects for class constructors, primarily in JavaScript/TypeScript files, similar to how it's done for functions:

f = ai.gen_spec.treesitter({ a = "@function.outer", i = "@function.inner" }, {}),
x = ai.gen_spec.treesitter({ a = "@constructor.outer", i = "@constructor.inner" }, {}),

I have tried to replace function with constructor but unfortunately, it didn't worked.
I would really appreciate some help with this.
Thank you!

The input for gen_spec.treesitter() is a table with actually used captures. The suggested, easiest, and most currently common approach is to install nvim-treesitter/nvim-treesitter-textobjects and use its captures. It has a curated list of captures it uses.

So it looks like using '@class.outer' and '@class.inner' should be the solution here. You can see how specific capture is created in the filetype's query file (here is one for 'typescript'); it is usually more or less clear from names which part a capture defines.
