--- Basename Register: returns the current filename without path and extension.
---
--- This is similar to the "%" register (full filename), but returns only
--- the basename with one extension removed. Useful, for example, when referencing
--- Java class names based on the file name.
---
--- This register is read-only and assigned to the character '$'.

local userregs = require("vim.userregs")
local api = vim.api

---@type table<string, fun(regname: string): any>
local handler = {}

--- Return the current buffer's basename without extension.
--- Equivalent to `expand('%:t:r')`
function handler.put(regname)
  return vim.fn.expand('%:t:r')
end

-- Make this register read-only by omitting the yank handler.
handler.yank = nil

-- Register this handler under the user register '$'.
userregs.register_handler('$', handler)
