# Swayr is a window switcher (and more) for sway [![builds.sr.ht status](https://builds.sr.ht/~tsdh/swayr.svg)](https://builds.sr.ht/~tsdh/swayr?) [![latest release](https://img.shields.io/crates/v/swayr.svg)](https://crates.io/crates/swayr) [![License GPL 3 or later](https://img.shields.io/crates/l/swayr.svg)](https://www.gnu.org/licenses/gpl-3.0.en.html) [![dependency status](https://deps.rs/repo/sourcehut/~tsdh/swayr/status.svg)](https://deps.rs/repo/sourcehut/~tsdh/swayr) [![Hits-of-Code](https://hitsofcode.com/sourcehut/~tsdh/swayr?branch=main)](https://hitsofcode.com/sourcehut/~tsdh/swayr/view?branch=main) Swayr consists of a demon, and a client. The demon `swayrd` records window/workspace creations, deletions, and focus changes using sway's JSON IPC interface. The client `swayr` offers subcommands, see `swayr --help`, and sends them to the demon which executes them. Right now, there are these subcommands: * `switch-to-urgent-or-lru-window` switches to the next window with urgency hint (if any) or to the last recently used window. * `switch-to-app-or-urgent-or-lru-window` switches to a specific window matched by application ID or window class unless it's already focused. In that case, it acts just like `switch-to-urgent-or-lru-window`. For example, you can provide "firefox" as argument to this command to have a convenient firefox <-> last-recently-used window toggle. * `switch-to-mark-or-urgent-or-lru-window` switches to a specific window matched by mark (`con_mark`) unless it's already focused. In that case, it acts just like `switch-to-urgent-or-lru-window`. For example, you can assign a "browser" mark to your browser window (using a standard sway `for_window` rule). Then you can provide "browser" as argument to this command to have a convenient browser <-> last-recently-used window toggle. * `switch-window` displays all windows in the order urgent first, then last-recently-used, focused last and focuses the selected. * `switch-workspace` displays all workspaces in LRU order and switches to the selected one. * `switch-output` shows all outputs in the menu and focuses the selected one. * `switch-workspace-or-window` displays all workspaces and their windows and switches to the selected workspace or window. * `switch-workspace-container-or-window` shows workspaces, containers, and their windows in the menu program and switches to the selected one. * `switch-to` shows outputs, workspaces, containers, and their windows in the menu program and switches to the selected one. * `quit-window` displays all windows and quits the selected one. An optional `--kill` / `-k` flag may be specified in which case the window's process will be killed using `kill -9 ` rather than only sending a `kill` IPC message to sway. * `quit-workspace-or-window` displays all workspaces and their windows and allows to quit either the selected workspace (all its windows) or the selected window. * `quit-workspace-container-or-window` shows workspaces, containers, and their windows and quits all windows of the selected workspace/container or the selected window. * `move-focused-to-workspace` moves the currently focused window or container to another workspace selected with the menu program. Non-matching input of the form `#w:` where the hash and `w:` shortcut are optional can be used to move it to a new workspace. * `move-focused-to` moves the currently focused container or window to the selected output, workspace, container, window. Non-matching input is handled like with `move-focused-to-workspace`. * `swap-focused-with` swaps the currently focused window or container with the one selected from the menu program. * `next-window (all-workspaces|current-workspace)` & `prev-window (all-workspaces|current-workspace)` focus the next/previous window in depth-first iteration order of the tree. The argument `all-workspaces` or `current-workspace` define if all windows of all workspaces or only those of the current workspace are considered. * `next-tiled-window` & `prev-tiled-window` do the same as `next-window` & `prev-window` but switch only between windows contained in a tiled container. * `next-tabbed-or-stacked-window` & `prev-tabbed-or-stacked-window` do the same as `next-window` & `prev-window` but switch only between windows contained in a tabbed or stacked container. * `next-floating-window` & `prev-floating-window` do the same as `next-window` & `prev-window` but switch only between floating windows. * `next-window-of-same-layout` & `prev-window-of-same-layout` is like `next-floating-window` / `prev-floating-window` if the current window is floating, it is like `next-tabbed-or-stacked-window` / `prev-tabbed-or-stacked-window` if the current window is in a tabbed or stacked container, it is like `next-tiled-window` / `prev-tiled-window` if the current windows is in a tiled container, and is like `next-window` / `prev-window` otherwise. * `tile-workspace exclude-floating|include-floating` tiles all windows on the current workspace (excluding or including floating ones). That's done by moving all windows away to some special workspace, setting the current workspace to `splith` layout, and then moving the windows back. If the `auto_tile` feature is used, see the Configuration section below, it'll change from splitting horizontally to vertically during re-insertion. * `shuffle-tile-workspace exclude-floating|include-floating` shuffles & tiles all windows on the current workspace. The shuffle part means that (a) the windows are shuffled before re-insertion, and (b) a randomly chosen already re-inserted window is focused before re-inserting another window. So while `tile-workspace` on a typical horizontally oriented screen and 5 windows will usually result in a layout with one window on the left and all four others tiled vertially on the right, `shuffle-tile-workspace` in combination with `auto_tile` usually results in a more balanced layout, i.e., 2 windows tiled vertically on the right and the other 4 tiled vertially on the left. If you have less than a handful of windows, just repeat `shuffle-tile-workspace` a few times until happenstance creates the layout you wanted. * `tab-workspace exclude-floating|include-floating` puts all windows of the current workspace into a tabbed container. * `toggle-tab-shuffle-tile-workspace exclude-floating|include-floating` toggles between a tabbed and tiled layout, i.e., it calls `shuffle-tile-workspace` if it is currently tabbed, and calls `shuffle-tile-workspace` if it is currently tiled. * `configure-outputs` lets you repeatedly issue output configuration commands until you abort the menu program. * `execute-swaymsg-command` displays most swaymsg which don't require additional input and executes the selected one. That's handy especially for less often used commands not bound to a key. Non-matching input will be executed executed as-is with `swaymsg`. * `execute-swayr-command` displays all commands above and executes the selected one. (This is useful for accessing swayr commands which are not bound to a key.) ### Menu shortcuts for non-matching input All menu switching commands (`switch-window`, `switch-workspace`, and `switch-workspace-or-window`) now handle non-matching input instead of doing nothing. The input should start with any number of `#` (in order to be able to force a non-match), a shortcut followed by a colon, and some string as required by the shortcut. The following shortcuts are supported. - `w:`: Switches to a possibly non-existing workspace. `` must be a digit, a name or `:`. The `:` format is explained in `man 5 sway`. If that format is given, `swayr` will create the workspace using `workspace number :`. If just a digit or name is given, the `number` argument is not used. - `s:`: Executes the sway command `` using `swaymsg`. - Any other input is assumed to be a workspace name and thus handled as `w:` would do. ## Screenshots ![A screenshot of swayr switch-window](misc/switch-window.png "swayr switch-window") ![A screenshot of swayr switch-workspace-or-window](misc/switch-workspace-or-window.png "swayr switch-workspace-or-window") ## Installation Some distros have packaged swayr so that you can install it using your distro's package manager. Alternatively, it's easy to build and install it yourself using `cargo`. ### Distro packages The following GNU/Linux and BSD distros package swayr. Thanks a lot to the respective package maintainers! Refer to the [repology site](https://repology.org/project/swayr/versions) for details. [![Packaging status](https://repology.org/badge/vertical-allrepos/swayr.svg)](https://repology.org/project/swayr/versions) [![AUR swayr-git package status](https://repology.org/badge/version-for-repo/aur/swayr.svg?allow_ignored=yes&header=AUR%20swayr-git)](https://repology.org/project/swayr/versions) ### Building with cargo You'll need to install the current stable rust toolchain using the one-liner shown at the [official rust installation page](https://www.rust-lang.org/tools/install). Then you can install swayr like so: ```sh cargo install swayr ``` For getting updates easily, I recommend the cargo `install-update` plugin. ```sh # Install it once. cargo install install-update # Then you can update all installed rust binary crates including swayr using: cargo install-update --all # If you only want to update swayr, you can do so using: cargo install-update -- swayr ``` ## Usage You need to start the swayr demon `swayrd` in your sway config (`~/.config/sway/config`) like so: ``` exec env RUST_BACKTRACE=1 RUST_LOG=swayr=debug swayrd > /tmp/swayrd.log 2>&1 ``` The setting of `RUST_BACKTRACE=1`, `RUST_LOG=swayr=debug` and the redirection of the output to some logfile is optional but helps a lot when something doesn't work. Especially, if you encounter a crash in certain situations and you want to report a bug, it would be utmost helpful if you could reproduce the issue with backtrace and logging at the `debug` level and attach that to your bug report. Valid log levels in the order from logging more to logging less are: `trace`, `debug`, `info`, `warn`, `error`, `off`. Next to starting the demon, you want to bind swayr commands to some keys like so: ``` bindsym $mod+Space exec env RUST_BACKTRACE=1 \ swayr switch-window >> /tmp/swayr.log 2>&1 bindsym $mod+Delete exec env RUST_BACKTRACE=1 \ swayr quit-window >> /tmp/swayr.log 2>&1 bindsym $mod+Tab exec env RUST_BACKTRACE=1 \ swayr switch-to-urgent-or-lru-window >> /tmp/swayr.log 2>&1 bindsym $mod+Next exec env RUST_BACKTRACE=1 \ swayr next-window all-workspaces >> /tmp/swayr.log 2>&2 bindsym $mod+Prior exec env RUST_BACKTRACE=1 \ swayr prev-window all-workspaces >> /tmp/swayr.log 2>&2 bindsym $mod+Shift+Space exec env RUST_BACKTRACE=1 \ swayr switch-workspace-or-window >> /tmp/swayr.log 2>&1 bindsym $mod+c exec env RUST_BACKTRACE=1 \ swayr execute-swaymsg-command >> /tmp/swayr.log 2>&1 bindsym $mod+Shift+c exec env RUST_BACKTRACE=1 \ swayr execute-swayr-command >> /tmp/swayr.log 2>&1 ``` Of course, configure the keys to your liking. Again, enabling rust backtraces and logging are optional. ## Configuration Swayr can be configured using the `~/.config/swayr/config.toml` or `/etc/xdg/swayr/config.toml` config file. If no config files exists, a simple default configuration will be created on the first invocation for use with the [wofi](https://todo.sr.ht/~scoopta/wofi) menu program. It should be easy to adapt that default config for usage with other menu programs such as [dmenu](https://tools.suckless.org/dmenu/), [bemenu](https://github.com/Cloudef/bemenu), [rofi](https://github.com/davatorium/rofi), a script spawning a terminal with [fzf](https://github.com/junegunn/fzf), or whatever. The only requirement is that the launcher needs to be able to read the items to choose from from stdin and spit out the selected item to stdout. The default config looks like this: ```toml [menu] executable = 'wofi' args = [ '--show=dmenu', '--allow-markup', '--allow-images', '--insensitive', '--cache-file=/dev/null', '--parse-search', '--height=40%', '--prompt={prompt}', ] [format] output_format = '{indent}Output {name} ({id})' workspace_format = '{indent}Workspace {name} [{layout}] ({id})' container_format = '{indent}Container [{layout}] on workspace {workspace_name} {marks} ({id})' window_format = 'img:{app_icon}:text:{indent}{app_name} — {urgency_start}“{title}”{urgency_end} on workspace {workspace_name} {marks} ({id})' indent = ' ' urgency_start = '' urgency_end = '' html_escape = true icon_dirs = [ '/usr/share/icons/hicolor/scalable/apps', '/usr/share/icons/hicolor/64x64/apps', '/usr/share/icons/hicolor/48x48/apps', '/usr/share/icons/Adwaita/64x64/apps', '/usr/share/icons/Adwaita/48x48/apps', '/usr/share/pixmaps', ] [layout] auto_tile = false auto_tile_min_window_width_per_output_width = [ [1024, 500], [1280, 600], [1400, 680], [1440, 700], [1600, 780], [1920, 920], [2560, 1000], [3440, 1000], [4096, 1200], ] ``` In the following, all sections are explained. ### The menu section In the `[menu]` section, you can specify the menu program using the `executable` name or full path and the `args` (flags and options) it should get passed. If some argument contains the placeholder `{prompt}`, it is replaced with a prompt such as "Switch to window" depending on context. ### The format section In the `[format]` section, format strings are specified defining how selection choices are to be layed out. `wofi` supports [pango markup](https://docs.gtk.org/Pango/pango_markup.html) which makes it possible to style the text using HTML and CSS. The following formats are supported right now. * `output_format` defines how outputs (monitors) are displayed in the menu program, `workspace_format` defines how workspaces are displayed, `container_format` defines how non-workspace containers are displayed, and `window_format` defines how application windows are displayed. * In these formats, the following placeholders can be used: * `{name}` gets replaced by the output name, the workspace number or name or a window's title. The placeholder `{title}` is an obsolete synonym which will be removed in a later version. * `{layout}` shows the workspace or container's layout. * `{id}` gets replaced by the sway-internal con id. * `{indent}` gets replaced with N times the new `format.indent` value where N is the depth in the shown menu input. * `{app_name}` gets replaced with a window's application name. * `{marks}` shows a comma-separated list of the container's or window's marks. * `{app_icon}` shows the application's icon (a path to a PNG or SVG file). * `{workspace_name}` gets replaced with the name or number of the workspace the container or window belongs to. * The placeholders `{urgency_start}` and `{urgency_end}` get replaced by the empty string if the window has no urgency flag and with the values of the same-named formats if the window has the urgency flag set. That makes it possible to highlight urgent windows as shown in the default config. * `indent` is a string which is repeatedly inserted at the `{indent}` placeholder in formats. * `html_escape` defines if the strings replacing the placeholders above (except for `{urgency_start}` and `{urgency_end}`) should be HTML-escaped. * `urgency_start` is a string which replaces the `{urgency_start}` placeholder in `window_format`. * `urgency_end` is a string which replaces the `{urgency_end}` placeholder in `window_format`. * `icon_dirs` is a vector of directories in which to look for application icons in order to compute the `{app_icon}` replacement. * `fallback_icon` is a path to some PNG/SVG icon which will be used as `{app_icon}` if no application-specific icon can be determined. All the placeholders except `{app_icon}`, `{indent}`, `{urgency_start}`, and `{urgency_end}` may optionally provide a format string as specified by [Rust's std::fmt](https://doc.rust-lang.org/std/fmt/). The syntax is `{:}`. For example, `{app_name:{:>10.10}}` would mean that the application name is printed with exactly 10 characters. If it's shorter, it will be right-aligned (the `>`) and padded with spaces, if it's longer, it'll be cut after the 10th character. Another example, `{app_name:{:.10}...}` would mean that the application name is truncated at 10 characters. If it's shorter, it will be printed as-is (no padding), if it's longer, it'll be cut after the 10th character and the last 3 characters of that substring will be replaced with `...` (``). It is crucial that during selection (using wofi or some other menu program) each window has a different display string. Therefore, it is highly recommended to include the `{id}` placeholder at least in `container_format` and `window_format`. Otherwise, e.g., two vertical splits on the same workspace or two terminals (of the same terminal app) with the same working directory (and therefore, the same title) wouldn't be distinguishable. **Hint for wofi**: `wofi` supports icons with the syntax `'img::text:'`, so a suitable `window_format` with application icon should start with `img:{app_icon}:text:`. **Hint for rofi**: `rofi` supports icons with the syntax `"\u0000icon\u00001f"`, so a suitable `window_format` with application icon should end with `"\u0000icon\u001f"`. Also note that you must enclose your `window_format` value with double-quotes and not with single-quotes. Singe-quote strings are literal strings in [TOML](https://toml.io/en/v1.0.0#string) where no escape-sequences are processed whereas for double-quoted strings (so-called basic strings) escape-sequences are processed. `rofi` requires a null character and a PARAGRAPH SEPARATOR for image sequences. ### The layout section In the `[layout]` section, you can enable auto-tiling by setting `auto_tile` to `true` (the default is `false`). The option `auto_tile_min_window_width_per_output_width` defines the minimum width in pixels which your windows should have per output width. For example, the example setting above says that on an output which is 1600 pixels wide, each window should have at least a width of 780 pixels, thus there may be at most two side-by-side windows (Caution, include your borders and gaps in your calculation!). There will be no auto-tiling doesn't include your output's exact width. If `auto_tile` is enabled, swayr will automatically split either vertically or horizontally according to this algorithm: - For all outputs: + For all (nested) containers on that output (except the scratchpad): - For all child windows of that container: + If the container is split horizontally and creating another window would make the current child window smaller than the minimum width, execute `split vertical` (the `swaymsg` command over IPC) on the child. + Else if the container is split vertically and now there is enough space so that creating another window would still leave the current child window above or equal to the minimum width, call `split horizontal` on the child. + Otherwise, do nothing for this container. This means that stacked or tabbed containers will never be affected by auto-tiling. There is one caveat: it would be nice to also trigger auto-tiling when windows or containers are resized but unfortunately, resizing doesn't issue any events over IPC. Therefore, auto-tiling is triggered by new-window events, close-events, move-events, floating-events, and also focus-events. The latter are a workaround and wouldn't be required if there were resize-events. ## Version Changes Since version 0.8.0, I've started writing a [NEWS](NEWS.md) file listing the news, and changes to `swayr` commands or configuration options. If something doesn't seem to work as expected after an update, please consult this file to check if there has been some (possibly incompatible) change requiring an update of your config. ## Questions & Patches For asking questions, sending feedback, or patches, refer to [my public inbox (mailinglist)](https://lists.sr.ht/~tsdh/public-inbox).
