-- Filetype detection logic is encoded in three tables:
-- 1. `extension` for literal extension lookup
-- 2. `filename` for literal full path or basename lookup;
-- 3. `pattern` for matching filenames or paths against Lua patterns,
--     optimized for fast lookup.
-- See `:h dev-vimpatch-filetype` for guidance when porting Vim filetype patches.

--- @class vim.filetype.add.filetypes
--- @inlinedoc
--- @field pattern? vim.filetype.mapping
--- @field extension? vim.filetype.mapping
--- @field filename? vim.filetype.mapping

--- Add new filetype mappings.
---
--- Filetype mappings can be added either by extension or by filename (either
--- the "tail" or the full file path). The full file path is checked first,
--- followed by the file name. If a match is not found using the filename, then
--- the filename is matched against the list of |lua-pattern|s (sorted by priority)
--- until a match is found. Lastly, if pattern matching does not find a
--- filetype, then the file extension is used.
---
--- The filetype can be either a string (in which case it is used as the
--- filetype directly) or a function. If a function, it takes the full path and
--- buffer number of the file as arguments (along with captures from the matched
--- pattern, if any) and should return a string that will be used as the
--- buffer's filetype. Optionally, the function can return a second function
--- value which, when called, modifies the state of the buffer. This can be used
--- to, for example, set filetype-specific buffer variables. This function will
--- be called by Nvim before setting the buffer's filetype.
---
--- Filename patterns can specify an optional priority to resolve cases when a
--- file path matches multiple patterns. Higher priorities are matched first.
--- When omitted, the priority defaults to 0.
--- A pattern can contain environment variables of the form "${SOME_VAR}" that will
--- be automatically expanded. If the environment variable is not set, the pattern
--- won't be matched.
---
--- See $VIMRUNTIME/lua/vim/filetype.lua for more examples.
---
--- Example:
---
--- ```lua
--- vim.filetype.add({
---   extension = {
---     foo = 'fooscript',
---     bar = function(path, bufnr)
---       if some_condition() then
---         return 'barscript', function(bufnr)
---           -- Set a buffer variable
---           vim.b[bufnr].barscript_version = 2
---         end
---       end
---       return 'bar'
---     end,
---   },
---   filename = {
---     ['.foorc'] = 'toml',
---     ['/etc/foo/config'] = 'toml',
---   },
---   pattern = {
---     ['.*/etc/foo/.*'] = 'fooscript',
---     -- Using an optional priority
---     ['.*/etc/foo/.*%.conf'] = { 'dosini', { priority = 10 } },
---     -- A pattern containing an environment variable
---     ['${XDG_CONFIG_HOME}/foo/git'] = 'git',
---     ['.*README.(%a+)'] = function(path, bufnr, ext)
---       if ext == 'md' then
---         return 'markdown'
---       elseif ext == 'rst' then
---         return 'rst'
---       end
---     end,
---   },
--- })
--- ```
---
--- To add a fallback match on contents, use
---
--- ```lua
--- vim.filetype.add {
---   pattern = {
---     ['.*'] = {
---       function(path, bufnr)

--- Buffer number to use for matching. Mutually exclusive with {contents}
--- @field buf? integer
---
--- Filename to use for matching. When {buf} is given,
--- defaults to the filename of the given buffer number. The
--- file need not actually exist in the filesystem. When used
--- without {buf} only the name of the file is used for
--- filetype matching. This may result in failure to detect

--- @field filename? string
---
--- An array of lines representing file contents to use for
--- matching. Can be used with {filename}. Mutually exclusive
--- with {buf}.
--- @field contents? string[]

--- Perform filetype detection.
---
--- The filetype can be detected using one of three methods:
--- 1. Using an existing buffer
--- 2. Using only a file name
--- 3. Using only file contents
---
--- Of these, option 1 provides the most accurate result as it uses both the buffer's filename and
--- (optionally) the buffer contents. Options 2 and 3 can be used without an existing buffer, but
--- may not always provide a match in cases where the filename (or contents) cannot unambiguously
--- determine the filetype.
---
--- Each of the three options is specified using a key to the single argument of this function.
--- Example:
---
--- ```lua
--- -- Using a buffer number
--- vim.filetype.match({ buf = 42 })
---
--- -- Override the filename of the given buffer
--- vim.filetype.match({ buf = 42, filename = 'foo.c' })
---
--- -- Using a filename without a buffer
--- vim.filetype.match({ filename = 'main.lua' })
---
--- -- Using file contents
--- vim.filetype.match({ contents = {'#!/usr/bin/env bash'} })
--- ```
---

---@return boolean|nil  # true if a match was found by falling back to a generic filetype
---                     (i.e., ".conf"), which indicates the filetype should be set with
