Updating Config Files

Tips for converting .ns config files to .lua format

The new .lua format uses the Lua programming language, so looking up the syntax may be helpful but if you've worked with the .ns config before, you should be able to read/write .lua format pretty easily.

Variables/Key Objects

config.ns

var vim_keys = #{
    "H": "Left",
    "J": "Down",
    "K": "Up",
    "L": "Right",
}

init.lua

local vim_keys = {
  h = "left",
  j = "down",
  k = "up",
  l = "right"
}

Note the following:

• local instead of var
• no # at the start of the object
• lowercase
• no quotes in the key value (h instead of "h")
• = instead of :

The range function has been removed and instead you can just create a lua table.

config.ns

nog.bind_arr("Alt", nog.workspace.change, range(workspace_count))

init.lua

local workspaces = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }
nog.nbind_tbl("alt", nog.ws_change, workspaces)

Workspace/Window

In .ns files, functions that were workspace- or window- specific were prefixed with workspace. or window.. In .lua those same functions are prefixed with ws_ or win_.

config.ns

nog.workspace.set_split_direction("Vertical")
nog.bind("Alt+Shift+Q", nog.window.close)

init.lua

nog.ws_set_split_direction("Vertical")
nog.nbind("alt+shift+q", nog.win_close)

Binding

In .ns files, using a table/object type to bind multiple values at once was done with bind_map. Instead, in .lua bind_tbl should be used.

config.ns

nog.bind_map("Alt", nog.workspace.focus, vim_keys)

init.lua

nog.nbind_tbl("alt", nog.ws_focus, vim_keys)

Also note, binding specifically to Normal, Work or Global uses an n, w, or g prefix:

nog.nbind("alt+f", nog.ws_toggle_fullscreen) -- only in the current mode/normal mode
nog.gbind("alt+f", nog.ws_toggle_fullscreen) -- always bound
nog.wbind("alt+f", nog.ws_toggle_fullscreen) -- bound only in work mode

User-defined Functions

Functions in .ns files were declared with () => { }. In .lua, they follow this syntax function() end

config.ns

nog.bind("Alt+Shift+Enter", () => nog.launch("notepad.exe"))

init.ns

nog.nbind("Alt+Shift+Enter", function () 
    nog.launch("notepad.exe")
end)

Setting Config Values

config.ns

nog.config.enable("display_app_bar");

init.lua

nog.config.display_app_bar = true

Pretty straightforward for setting an initial value; use an = and true/false value or a number for an integer type. There no longer are enable, disable, increment, decrement or toggle functions. Instead, they can be handled with user-defined functions.

enable function

nog.nbind("alt+t", function ()
    nog.config.display_app_bar = true
end)

disable function

nog.nbind("alt+t", function ()
    nog.config.display_app_bar = false
end)

toggle function

nog.nbind("alt+t", function ()
    nog.config.display_app_bar = not nog.config.display_app_bar 
end)

increment function

nog.nbind("alt+t", function ()
    nog.config.inner_gap = nog.config.inner_gap + 1
end)

decrement function

nog.nbind("alt+t", function ()
    nog.config.inner_gap = nog.config.inner_gap - 1
end)

Configuring Bar

A few bar config values can now be set on the nog.config object and the syntax for defining components is slightly different.

config.ns

nog.bar.configure(#{
    height: 16,
    font_size: 20,
    font: "Fixedsys",
    components: #{
        left: [components.workspaces()],
        center: [components.current_window()],
        right: [
            components.active_mode(),
            components.padding(4),
            components.fullscreen_indicator("[]"),
            components.padding(1),
            components.split_direction("|", "-"),
            components.padding(1),
            components.date("%e %b"),
            components.padding(1),
            components.time("%T"),
            components.padding(1)
        ]
    }
})

init.lua

nog.config.bar.height = 16
nog.config.bar.font_size = 20
nog.config.bar.font = "Fixedsys"

nog.config.bar.components = {
    left = { nog.components.workspaces() },
    center = { nog.components.current_window() },
    right = {
        nog.components.active_mode(),
        nog.components.padding(4),
        nog.components.fullscreen_indicator("[]"),
        nog.components.padding(1),
        nog.components.split_direction({ "|", "-" }),
        nog.components.padding(1),
        nog.components.datetime("%e %b %T"),

    }
}

Note:

• split_direction takes a table { "|", "-" } instead of two parameters "|", "-"
• Date/Time has changed from date("%e %b") and time("%T") to just datetime("%e %b %T")

Rules

config.ns

var ignored = [
    "explorer.exe",
    "Taskmgr.exe",
    "SnippingTool.exe",
]
ignored.for_each(nog.rules.ignore);


nog.rules.match("firefox.exe", #{
    has_custom_titlebar: true,
    firefox: true
})
nog.rules.match("chrome.exe", #{
    has_custom_titlebar: true,
    chromium: true
})

init.lua

nog.config.rules = {
  ["explorer.exe"] = { 
    ignore = true 
  },
  ["taskmgr.exe"] = { 
    ignore = true 
  },
  ["snippingtool.exe"] = { 
    ignore = true 
  },
  ["firefox.exe"] = {
    has_custom_titlebar = true,
    firefox = true
  },
  ["chrome.exe"] = {
    has_custom_titlebar = true,
    chromium = true
  },
}

Note:

• = instead of :
• keys are wrapped in [" "]

Modes

config.ns

mode("move", bind => {
    bind("Alt+M", () => nog.toggle_mode("move"))
    bind("Escape", () => nog.toggle_mode("move"))

    bind("W", () => nog.workspace.focus("Up"))
    bind("A", () => nog.workspace.focus("Left"))
    bind("S", () => nog.workspace.focus("Down"))
    bind("D", () => nog.workspace.focus("Right"))

    bind("H", () => nog.workspace.swap("Left"))
    bind("J", () => nog.workspace.swap("Down"))
    bind("K", () => nog.workspace.swap("Up"))
    bind("L", () => nog.workspace.swap("Right"))
})
nog.bind("Alt+M", () => nog.toggle_mode("move"))

init.lua

nog.mode("move", function()
    nog.nbind("Escape", function()
      nog.toggle_mode("move")
    end)
    nog.nbind("alt+m", function()
      nog.toggle_mode("move")
    end)

    nog.nbind("w", function() nog.ws_focus("up") end)
    nog.nbind("a", function() nog.ws_focus("left") end)
    nog.nbind("s", function() nog.ws_focus("down") end)
    nog.nbind("d", function() nog.ws_focus("right") end)

    nog.nbind("h", function() nog.ws_swap("Left") end)
    nog.nbind("j", function() nog.ws_swap("Down") end)
    nog.nbind("k", function() nog.ws_swap("Up") end)
    nog.nbind("l", function() nog.ws_swap("Right") end)
end)

Note:

• function () end vs () => syntax
