List userdata *lua-list* +! +! List userdata represent vim lists, and the interface tries to follow closely +! Vim's syntax for lists. Since lists are objects, changes in list references in +! Lua are reflected in Vim and vice-versa. A list "l" has the following +! properties and methods: +! +! Properties +! ---------- +! o "#l" is the number of items in list "l", equivalent to "len(l)" +! in Vim. +! o "l[k]" returns the k-th item in "l"; "l" is zero-indexed, as in Vim. +! To modify the k-th item, simply do "l[k] = newitem"; in +! particular, "l[k] = nil" removes the k-th item from "l". +! o "l()" returns an iterator for "l". +! +! Methods +! ------- +! o "l:add(item)" appends "item" to the end of "l". +! o "l:insert(item[, pos])" inserts "item" at (optional) +! position "pos" in the list. The default value for "pos" is 0. +! +! Examples: +! > +! :let l = [1, 'item'] +! :lua l = vim.eval('l') -- same 'l' +! :lua l:add(vim.list()) +! :lua l[0] = math.pi +! :echo l[0] " 3.141593 +! :lua l[0] = nil -- remove first item +! :lua l:insert(true, 1) +! :lua print(l, #l, l[0], l[1], l[-1]) +! :lua for item in l() do print(item) end +! < +! +! ============================================================================== +! 4. Dict userdata *lua-dict* +! +! Similarly to list userdata, dict userdata represent vim dictionaries; since +! dictionaries are also objects, references are kept between Lua and Vim. A dict +! "d" has the following properties: +! +! Properties +! ---------- +! o "#d" is the number of items in dict "d", equivalent to "len(d)" +! in Vim. +! o "d.key" or "d['key']" returns the value at entry "key" in "d". +! To modify the entry at this key, simply do "d.key = newvalue"; in +! particular, "d.key = nil" removes the entry from "d". +! o "d()" returns an iterator for "d" and is equivalent to "items(d)" in +! Vim. +! +! Examples: +! > +! :let d = {'n':10} +! :lua d = vim.eval('d') -- same 'd' +! :lua print(d, d.n, #d) +! :let d.self = d +! :lua for k, v in d() do print(d, k, v) end +! :lua d.x = math.pi +! :lua d.self = nil -- remove entry +! :echo d +! < +! +! ============================================================================== +! 5.

The luaeval function *lua-luaeval* +! +! The (dual) equivalent of "vim.eval" for passing Lua values to Vim is +! "luaeval". "luaeval" takes an expression string and an optional argument and +! returns the result of the expression.

Note that "_A" receives the argument to "luaeval".
