-- This file contains definitions of custom general and Leader mappings.

-- General mappings ===========================================================

-- Use this section to add custom general mappings. See `:h vim.keymap.set()`.

-- An example helper to create a Normal mode mapping
local nmap = function(lhs, rhs, desc)
  -- See `:h vim.keymap.set()`
  vim.keymap.set('n', lhs, rhs, { desc = desc })
end

-- stylua: ignore start
-- The next part (until `-- stylua: ignore end`) is aligned manually for easier
-- reading. Consider preserving this or remove `-- stylua` lines to autoformat.

-- Leader mappings ============================================================

-- Neovim has the concept of a Leader key (see `:h <Leader>`). It is a configurable
-- key that is primarily used for "workflow" mappings (opposed to text editing).
-- Like "open file explorer", "create scratch buffer", "pick from buffers".
--
-- In 'plugin/10_options.lua' <Leader> is set to <Space>, i.e. press <Space>
-- whenever there is a suggestion to press <Leader>.
--
-- Create a global table with information about Leader groups in certain modes.
-- This is used to provide 'mini.clue' with extra clues.
-- Add an entry if you create a new group.
_G.Config.leader_group_clues = {
  { mode = 'n', keys = '<Leader>b', desc = '+Buffer' },
  { mode = 'n', keys = '<Leader>e', desc = '+Explore/Edit' },
  { mode = 'n', keys = '<Leader>f', desc = '+Pick' },
  { mode = 'n', keys = '<Leader>g', desc = '+Git' },
  { mode = 'n', keys = '<Leader>l', desc = '+Language' },
  { mode = 'n', keys = '<Leader>m', desc = '+Map' },
  { mode = 'n', keys = '<Leader>o', desc = '+Other' },
  { mode = 'n', keys = '<Leader>s', desc = '+Session' },
  { mode = 'x', keys = '<Leader>g', desc = '+Git' },
  { mode = 'x', keys = '<Leader>z', desc = '+Notes' },
}

-- Helpers for a more concise `<Leader>` mappings.
-- Most of the mappings use `<Cmd>...<CR>` string as a right hand side (RHS) in
-- an attempt to be more concise yet descriptive. See `:h <Cmd>`.
-- This approach also doesn't require the underlying commands/functions to exist
-- during mapping creation: a "lazy loading" approach to improve startup time.

-- b is for 'Buffer'. Common usage:
-- - `<Leader>bs` - create scratch (temporary) buffer
-- - `<Leader>ba` - navigate to the alternative buffer

-- e is for 'Explore' and 'Edit'. Common usage:
-- - `<Leader>ed` - open explorer at current working directory
-- - `<Leader>ef` - open directory of current file (needs to be present on disk)
-- - `<Leader>ei` - edit 'init.lua'
-- - All mappings that use `edit_plugin_file` - edit 'plugin/' config files

-- f is for 'Fuzzy Find'. Common usage:
-- - `<Leader>ff` - find files; for best performance requires `ripgrep`

-- - `<Leader>fr` - resume latest picker
-- - `<Leader>fv` - all visited paths; requires 'mini.visits'
--
-- All these use 'mini.pick'. See `:h MiniPick-overview` for an overview.
