Quake ----- A Quake-like dropdown container for your favourite application. **Usage** Define it globally to have a single instance for all screens: ```lua local quake = lain.util.quake() ``` or define it in `connect_for_each_screen` to have one instance for each screen: ```lua awful.screen.connect_for_each_screen(function(s) -- Quake application s.quake = lain.util.quake() -- [...] ``` **Keybinding example** If using a global instance: ```lua awful.key({ modkey, }, "z", function () quake:toggle() end), ``` If using a per-screen instance: ```lua awful.key({ modkey, }, "z", function () awful.screen.focused().quake:toggle() end), ``` **Input table** Variable | Meaning | Type | Default --- | --- | --- | --- `app` | client to spawn | string | "xterm" `name` | client name | string | "QuakeDD" `argname` | how to specify client name | string | "-name %s" `extra` | extra `app` arguments | string | empty string `border` | border width | integer | 1 `visible` | initially visible | boolean | false `followtag` | always spawn on currently focused screen | boolean | false `overlap` | Overlap the wibox or not | boolean | false `settings` | Additional settings to make on the client | function | `nil` `screen` | screen where to spawn the client | integer | `awful.screen.focused()` `height` | dropdown client height | float in [0,1] or exact pixels number | 0.25 `width` | dropdown client width | float in [0,1] or exact pixels number | 1 `vert` | vertical position | string, possible values: "top", "bottom", "center" | "top" `horiz` | horizontal position | string, possible values: "left", "right", "center" | "left" `height` and `width` express a fraction of the workspace. `settings` is a function which takes the client as input, and can be used to customize its properties. For instance: ```lua -- set the client sticky s.quake = lain.util.quake { settings = function(c) c.sticky = true end } ``` Read [here](https://awesomewm.org/doc/api/classes/client.html#Object_properties) for the complete list of properties. **Notes** * [Does not work](https://github.com/lcpz/lain/issues/358) with `gnome-terminal`, `konsole`, or any other terminal which is strictly designed for a Desktop Environment. Just pick a better terminal, [there's plenty](https://wiki.archlinux.org/index.php/List_of_applications#Terminal_emulators). * Set `followtag = true` if [experiencing issues with multiple screens](https://github.com/lcpz/lain/issues/346). * If you have a `awful.client.setslave` rule for your application, ensure you use an exception for `QuakeDD` (or your defined `name`). Otherwise, you may run into problems with focus. * If you are using a VTE-based terminal like `termite`, be sure to set [`argname = "--name %s"`](https://github.com/lcpz/lain/issues/211). * If you are using a terminal that does not always set its `class_id` to your specified `name`, such as Alacritty, then toggling will not work. You can solve this issue as explained [here](https://github.com/lcpz/lain/issues/536#issuecomment-1180155486). Separators ---------- Adds Cairo separators. ```lua local separators = lain.util.separators ``` A separator function `separators.separator` takes two color arguments, defined as strings. `"alpha"` argument is allowed. Example: ```lua arrl_dl = separators.arrow_left(beautiful.bg_focus, "alpha") arrl_ld = separators.arrow_left("alpha", beautiful.bg_focus) ``` You can customize height and width by setting `separators_height` and `separators_width` in your `theme.lua`. Default values are 0 and 9, respectively. List of functions: +-- separators | |`-- arrow_right() Draw a right arrow. `-- arrow_left() Draw a left arrow. Markup ------ Easier markup. ```lua local markup = lain.util.markup ``` List of functions: +-- markup | |`-- bold() Set bold. |`-- italic() Set italicized text. |`-- strike() Set strikethrough text. |`-- underline() Set underlined text. |`-- monospace() Set monospaced text. |`-- big() Set bigger text. |`-- small() Set smaller text. |`-- font() Set the font of the text. |`-- font() Set the font of the text. |`-- color() Set background and foreground color. |`-- fontfg() Set font and foreground color. |`-- fontbg() Set font and background color. `-- fontcolor() Set font, plus background and foreground colors. | |`--+ bg | | | `-- color() Set background color. | `--+ fg | `-- color() Set foreground color. they all take one argument, which is the text to markup, except the following: ```lua markup.font(font, text) markup.color(fg, bg, text) markup.fontfg(font, fg, text) markup.fontbg(font, bg, text) markup.fontcolor(font, fg, bg, text) markup.fg.color(color, text) markup.bg.color(color, text) ``` Dynamic tagging --------------- That is: - add a new tag; - rename current tag; - move current tag; - delete current tag. If you delete a tag, any rule set on it shall be broken, so be careful. Use it with key bindings like these: ```lua awful.key({ modkey, "Shift" }, "n", function () lain.util.add_tag(mylayout) end), awful.key({ modkey, "Shift" }, "r", function () lain.util.rename_tag() end), awful.key({ modkey, "Shift" }, "Left", function () lain.util.move_tag(1) end), -- move to next tag awful.key({ modkey, "Shift" }, "Right", function () lain.util.move_tag(-1) end), -- move to previous tag awful.key({ modkey, "Shift" }, "d", function () lain.util.delete_tag() end), ``` The argument in `lain.util.add_tag` represents the tag layout, and is optional: if not present, it will be defaulted to `awful.layout.suit.tile`. Useless gaps resize --------------------- Changes `beautiful.useless_gaps` on the fly. ```lua lain.util.useless_gap_resize(thatmuch, s, t) ``` The argument `thatmuch` is the number of pixel to add to/substract from gaps (integer). The arguments `s` and `t` are the `awful.screen` and `awful.tag` in which you want to change the gap. They are optional. Following are example keybindings for changing client gaps on current screen and tag. Example 1: ```lua -- On the fly useless gaps change awful.key({ altkey, "Control" }, "+", function () lain.util.useless_gaps_resize(1) end), awful.key({ altkey, "Control" }, "-", function () lain.util.useless_gaps_resize(-1) end), ``` where `altkey = Mod1`. Example 2: ```lua mywidget:buttons(awful.util.table.join ( awful.button({}, 4, function() lain.util.useless_gaps_resize(-1) end), awful.button({}, 5, function() lain.util.useless_gaps_resize(1) end) end) )) ``` so when hovering the mouse over `mywidget`, you can adjust useless gaps size by scrolling with the mouse wheel. tag\_view\_nonempty ------------------- This function lets you jump to the next/previous non-empty tag. It takes two arguments: * `direction`: `1` for next non-empty tag, `-1` for previous. * `sc`: Screen which the taglist is in. Default is `mouse.screen` or `1`. This argument is optional. You can use it with key bindings like these: ```lua -- Non-empty tag browsing awful.key({ altkey }, "Left", function () lain.util.tag_view_nonempty(-1) end), awful.key({ altkey }, "Right", function () lain.util.tag_view_nonempty(1) end), ``` where `altkey = "Mod1"`. magnify\_client --------------- Set a client to floating and resize it in the same way the "magnifier" layout does it. Place it on the "current" screen (derived from the mouse position). This allows you to magnify any client you wish, regardless of the currently used layout. Use it with a client keybinding like this: ```lua clientkeys = awful.util.table.join( -- [...] awful.key({ modkey, "Control" }, "m", lain.util.magnify_client), -- [...] ) ``` If you want to "de-magnify" it, just retype the keybinding. If you want magnified client to respond to `incmwfact`, read [here](https://github.com/lcpz/lain/issues/195). menu\_clients\_current\_tags ---------------------------- Similar to `awful.menu.clients`, but this menu only shows the clients of currently visible tags. Use it with a key binding like this: ```lua awful.key({ "Mod1" }, "Tab", function() lain.util.menu_clients_current_tags({ width = 350 }, { keygrabber = true }) end), ``` menu\_iterator -------------- A generic menu utility which enables iteration over lists of possible actions to execute. The perfect example is a menu for choosing what configuration to apply to X with `xrandr`, as suggested on the [Awesome wiki page](https://awesomewm.org/recipes/xrandr).

You can either manually create a menu by defining a table in this format: ```lua { { "choice description 1", callbackFuction1 }, { "choice description 2", callbackFunction2 }, ... } ``` or use `lain.util.menu_iterator.menu`. Once you have your menu, use it with `lain.menu_iterator.iterate`. ### Input tables **lain.menu_iterator.iterate** | Argument | Description | Type |---|---| --- | `menu` | the menu to iterate on | table | `timeout` | time (in seconds) to wait on a choice before the choice is accepted | integer (default: 4) | `icon` | path to the icon to display in `naughty.notify` window | string **lain.menu_iterator.menu** | Argument | Description | Type |---|---| --- `choices` | list of choices (e.g., `{ "choice1", "choice2", ... }`) | array of strings `name` | name of the program related to this menu | string `selected_cb` | callback to execute for each selected choice, it takes one choice (string) as argument; can be `nil` (no action to execute) | function `rejected_cb` | callback to execute for all rejected choices (the remaining choices, once one is selected), it takes one choice (string) as argument; can be `nil` (no action to execute) | function `extra_choices` | more choices to be added to the menu; unlike `choices`, these ones won't trigger `rejected_cb` | array of `{ choice, callback }` pairs, where `choice` is a string and `callback` is a function `combination` | how choices have to be combined in the menu; possible values are: "single" (default), the set of possible choices will simply be the input set ; "powerset", the set of possible choices will be the [power set](https://en.wikipedia.org/wiki/Power_set) of the input set | string ### Examples A simple example is: ```lua local mymenu_iterable = lain.util.menu_iterator.menu { choices = {"My first choice", "My second choice"}, name = "My awesome program", selected_cb = function(choice) -- do something with selected choice end, rejected_cb = function(choice) -- do something with every rejected choice end } ``` The variable `mymenu_iterable` is a menu compatible with the function `lain.util.menu_iterator.iterate`, which will iterate over it and displays notification with `naughty.notify` every time it is called. You can use it like this: ```lua local confirm_timeout = 5 -- time to wait before confirming the menu selection local my_notify_icon = "/path/to/icon" -- the icon to display in the notification lain.util.menu_iterator.iterate(mymenu_iterable, confirm_timeout, my_notify_icon) ``` Once `confirm_timeout` has passed without anymore calls to `iterate`, the choice is made and the associated callbacks (both for selected and rejected choices) are spawned. A useful practice is to add a `Cancel` option as an extra choice for canceling a menu selection. Extending the above example: ```lua local mymenu_iterable = lain.util.menu_iterator.menu { choices = {"My first choice", "My second choice"}, name = "My awesome program", selected_cb = function(choice) -- do something with selected choice end, rejected_cb = function(choice) -- do something with every rejected choice end -- nil means no action to do extra_choices = { {"Cancel"}, nil } } ```
