How to use

local picked_window_id = require('window-picker').pick_window()

You can put the picked window id to good use

Configuration

If you want to have custom properties just for one time, you can pass any of following directly to pick_window() function itself to override the default behaviour.

require 'window-picker'.setup({
    -- type of hints you want to get
    -- following types are supported
    -- 'statusline-winbar' | 'floating-big-letter'
    -- 'statusline-winbar' draw on 'statusline' if possible, if not 'winbar' will be
    -- 'floating-big-letter' draw big letter on a floating window
    -- used
    hint = 'statusline-winbar',

    -- when you go to window selection mode, status bar will show one of
    -- following letters on them so you can use that letter to select the window
    selection_chars = 'FJDKSLA;CMRUEIWOQP',

    -- This section contains picker specific configurations
    picker_config = {
        statusline_winbar_picker = {
            -- You can change the display string in status bar.
            -- It supports '%' printf style. Such as `return char .. ': %f'` to display
            -- buffer file path. See :h 'stl' for details.
            selection_display = function(char, windowid)
                return '%=' .. char .. '%='
            end,

            -- whether you want to use winbar instead of the statusline
            -- "always" means to always use winbar,
            -- "never" means to never use winbar
            -- "smart" means to use winbar if cmdheight=0 and statusline if cmdheight > 0
            use_winbar = 'never', -- "always" | "never" | "smart"
        },

        floating_big_letter = {
            -- window picker plugin provides bunch of big letter fonts
            -- fonts will be lazy loaded as they are being requested
            -- additionally, user can pass in a table of fonts in to font
            -- property to use instead

            font = 'ansi-shadow', -- ansi-shadow |
        },
    },

    -- whether to show 'Pick window:' prompt
    show_prompt = true,

    -- prompt message to show to get the user input
    prompt_message = 'Pick window: ',

    -- if you want to manually filter out the windows, pass in a function that
    -- takes two parameters. You should return window ids that should be
    -- included in the selection
    -- EX:-
    -- function(window_ids, filters)
    --    -- folder the window_ids
    --    -- return only the ones you want to include
    --    return {1000, 1001}
    -- end
    filter_func = nil,

    -- following filters are only applied when you are using the default filter
    -- defined by this plugin. If you pass in a function to "filter_func"
    -- property, you are on your own
    filter_rules = {
        -- when there is only one window available to pick from, use that window
        -- without prompting the user to select
        autoselect_one = true,

        -- whether you want to include the window you are currently on to window
        -- selection or not
        include_current_win = false,

        -- filter using buffer options
        bo = {
            -- if the file type is one of following, the window will be ignored
            filetype = { 'NvimTree', 'neo-tree', 'notify' },

            -- if the file type is one of following, the window will be ignored
            buftype = { 'terminal' },
        },

        -- filter using window options
        wo = {},

        -- if the file path contains one of following names, the window
        -- will be ignored
        file_path_contains = {},

        -- if the file name contains one of following names, the window will be
        -- ignored
        file_name_contains = {},
    },

    -- You can pass in the highlight name or a table of content to set as
    -- highlight
    highlights = {
        statusline = {
            focused = {
                fg = '#ededed',
                bg = '#e35e4f',
                bold = true,
            },
            unfocused = {
                fg = '#ededed',
                bg = '#44cc41',
                bold = true,
            },
        },
        winbar = {
            focused = {
                fg = '#ededed',
                bg = '#e35e4f',
                bold = true,
            },
            unfocused = {
                fg = '#ededed',
                bg = '#44cc41',
                bold = true,
            },
        },
    },
})

require('window-picker').pick_window({
    hint = 'floating-big-letter'
})

Theming

If you just want to define the colors using Neovim Highlights, then it's totally possible. You can set following highlights manually.

Breaking changes in v2.0.0

Before: return value from selection_display will be wrapped by '%=' and '%=' to fill the empty space of status line or winbar.

After: return value of selection_display will be passed directly to the status line or winbar. This allows all the customizations available from statusline syntax. You can check :help statusline for more info.
