## Usage ## Usage
`i3toolwait -c FILE` - **simple:** `i3toolwait simple ...`
- **config:** `i3toolwait config ...`
Optionally start multiple programs and wait for their windows to appear. ### Simple
Once these windows appeared a custom i3 command can be specified.
## Example Run only one program.
### Config
Run multiple programs by specifying a yaml configuration file:
```yaml ```yaml
--- ---
timeout: 10000 signal: signal number or name, optional. Should program entries which have signal: true wait for this signal before continuing to the next one.
init: | timeout: timeout in milliseconds
(begin init: a lisp program, optional. Used to initialize the environment, useful to define custom functions which should be available everywhere.
(define i3_path ".container.window_properties.class")
(define sway_path ".container.app_id")
(defun idmatch (name) (== (if (has-key sway_path) (load sway_path) (load i3_path)) name))
(defun match (name) (and (== (load ".change") "new") (idmatch name)))
(defun match-load (name) (if (match name) (load ".container.id") F))
)
cmd: 'workspace 1'
programs: programs:
- run: 'exec gtk-launch librewolf' - match: a filter with which to match the window
cmd: 'for_window [con_id="{result}"] focus; move container to workspace 1' workspace: string or null, the workspace to move windows to
match: '(match-load "LibreWolf")' cmd: string or list, the command to execute
- run: 'exec gtk-launch nheko || gtk-launch io.element.Element' signal: boolean, should we wait before continuing with the next entry
cmd: 'for_window [con_id="{result}"] focus; move container to workspace 2' timeout: timeout in milliseconds, used only if signal: true - how long to wait for the signal
match: '(if (or (match "Electron") (match "nheko")) (load ".container.id") F)'
- run: 'exec gtk-launch thunderbird'
cmd: 'for_window [con_id="{result}"] focus; move container to workspace 3'
match: '(match-load "thunderbird")'
- run: 'exec nm-applet --indicator'
- run: 'exec blueman-applet'
- run: 'exec gtk-launch org.kde.kdeconnect.nonplasma'
- run: 'exec gtk-launch syncthing-gtk'
``` ```
## Configuration The programs will be started asynchronously, except when `signal = true` which means that, before continuing
to the next program we wait for a signal. I would start all programs, which do not wait for a signal first
and then only the ones depending on the signal to reduce the startup delay.
The configuration file is in YAML format. ## Installing
Use the makefile: `INSTALL_BASE=/usr/local/ make install` or install all dependencies
`python3 -mpip install --upgrade -r requirements.txt` and copy the script to your
path: `cp i3toolwait /usr/local/bin/i3toolwait`.
### Configuration ## Filtering
#### timeout: int The program allows to match the window or container based on the returned IPC data.
Some programs might open multiple windows (looking at you, Discord).
_Optional_ _Default_ `3000` In order to move the correct window to the desired workspace a filter can be defined.
Total program timeout in ms. The syntax for the filter is lisp-like. To view all spawned containers run the program
with `--debug --filter=False` which will not match any windows and print their properties.
#### init: String It is then possible to construct a filter for any program.
_Optional_ _Default_ `""` Available Operators:
Initialization program; Used to initialize the environment, useful - and: `&`: logical and, ungreedy
to define custom functions which should be available everywhere. - or: `|`: logical or, ungreedy
- if: `?`: branch, if the first argument evaluates to `True` return the second, otherwise the third
- eq: `=`: equality
- neq: `!=`: inequality
- gt: `>`: greater than
- lt: `<`: less than
- load: `load`: load a key from the provided input `(load ".container.app_id")`
- has-key: `has-key`: check if a key is in the input: `(has-key ".container.app_id")`
- let: `let`: assign a local variable: `(let x 10)`
- setq: `setq`: assign a global variable: `(setq x 11)`
- defun: `defun`: user-defined functions: `((defun greet (a) (write (+ "Hello " a "!"))) (greet "Alice"))`
#### cmd: String For example: `(> (load ".container.geometry.width") 300)` would match the first window where the width is greater than 300.
_Optional_ _Default_ `""` Multiple filters are combined via nesting: `(& (> (load ".container.geometry.width") 300) (= (load ".container.window_properties.class") "discord"))`.
A final i3 command to be executed before exiting. ## Starting tray programs in a specific order
#### programs: List[Union[[Program](#program), [Signal](#signal)]] To start tray programs in a specific order it is possible to specify the `signal` parameter.
Starting of programs will be halted until the program has received the corresponding signal.
_Optional_ _Default_ `[]` This could be combined with waybar to enforce an ordering of tray applications:
A list of programs to execute. `~/.config/waybar/config`
```json
"tray": {
"on-update": "pkill --full --signal SIGUSR1 i3toolwait",
"reverse-direction": true,
}
```
### Program `config-file`
```yaml
signal: SIGUSR1
timeout: 2000
init: |
(
(setq i3_path ".container.window_properties.class")
(setq sway_path ".container.app_id")
(defun "idmatch" (name) (= (? (has-key sway_path) (load sway_path) (load i3_path)) name))
)
programs:
- cmd: 'nm-applet --indicator'
match: '(False)'
timeout: 1000
signal: true
- cmd: 'blueman-applet'
match: '(False)'
timeout: 1000
signal: true
- ...
```
Launch all programs using [`run`](#run-string) and execute This setup would order the icons in waybar from left-to-right like in the config file.
[`cmd`](#cmd-string-1) once [`match`](#match-string) matches
a window.
#### match: String ## Troubleshooting
_Required_ ### My windows do not get rearranged
A lisp program which analyzes the i3 window event and returns a value. It is very likely that the timeout is too short and the program exits before the window spawns.
If the return value is `false` the window does not match and no Alternatively your filter might just be wrong. To debug execute the script with the `--debug`
further processing occurs. Otherwise the i3 command flag to see if the window is recognized.
[`cmd`](#cmd-string-1).
will be executed.
#### cmd: String
_Required_
A i3 command. Can contain a format `{result}` which gets replaced
by the output of the match command.
**Example:**
`for_window [con_id="{result}"] focus; move container to window 1`
#### run: String
_Optional_ _Default_ `null`
A i3 command which is run at program startup, can be used to launch
programs.
**Example:**
`exec gtk-launch firefox`
### Signal
Programs are launched in order and only advance after
[`timeout`](#timeout-int-1) or after receiving signal
`SIGUSR1`.
#### run: String
_Optional_ _Default_ `null`
A i3 command.
#### timeout: int
_Optional_ _Default_ `500`
How long to wait for the signal in ms.
