|
|
|
--- Add a new |mapping|.
|
|
--- Examples:
|
|
--- <pre>
|
|
--- -- Can add mapping to Lua functions
|
|
--- vim.keymap.set('n', 'lhs', function() print("real lua function") end)
|
|
---
|
|
--- -- Can use it to map multiple modes
|
|
--- vim.keymap.set({'n', 'v'}, '<leader>lr', vim.lsp.buf.references, { buffer=true })
|
|
---
|
|
--- -- Can add mapping for specific buffer
|
|
--- vim.keymap.set('n', '<leader>w', "<cmd>w<cr>", { silent = true, buffer = 5 })
|
|
---
|
|
--- -- Expr mappings
|
|
--- vim.keymap.set('i', '<Tab>', function()
|
|
--- return vim.fn.pumvisible() == 1 and "<C-n>" or "<Tab>"
|
|
--- end, { expr = true })
|
|
--- -- <Plug> mappings
|
|
--- vim.keymap.set('n', '[%%', '<Plug>(MatchitNormalMultiBackward)')
|
|
--- </pre>
|
|
---
|
|
--- Note that in a mapping like:
|
|
--- <pre>
|
|
--- vim.keymap.set('n', 'asdf', require('jkl').my_fun)
|
|
--- </pre>
|
|
---
|
|
--- the ``require('jkl')`` gets evaluated during this call in order to access the function.
|
|
--- If you want to avoid this cost at startup you can wrap it in a function, for example:
|
|
--- <pre>
|
|
--- vim.keymap.set('n', 'asdf', function() return require('jkl').my_fun() end)
|
|
--- </pre>
|
|
---
|
|
---@param mode string|table Same mode short names as |nvim_set_keymap()|.
|
|
--- Can also be list of modes to create mapping on multiple modes.
|
|
---@param lhs string Left-hand side |{lhs}| of the mapping.
|
|
---@param rhs string|function Right-hand side |{rhs}| of the mapping. Can also be a Lua function.
|

|
|
---@param opts table A table of |:map-arguments| such as "silent". In addition to the options
|
|
--- listed in |nvim_set_keymap()|, this table also accepts the following keys:
|
|
--- - replace_keycodes: (boolean, default true) When both this and expr is "true",
|
|
--- |nvim_replace_termcodes()| is applied to the result of Lua expr maps.
|
|
--- - remap: (boolean) Make the mapping recursive. This is the
|
|
--- inverse of the "noremap" option from |nvim_set_keymap()|.
|
|
--- Default `false`.

|
---@see |nvim_set_keymap()|
