@ -4,114 +4,125 @@ Launch a program and move it to the correct workspace.
|
|||
|
||||
## Usage
|
||||
|
||||
- **simple:** `i3toolwait simple ...`
|
||||
- **config:** `i3toolwait config ...`
|
||||
`i3toolwait -c FILE`
|
||||
|
||||
### Simple
|
||||
Optionally start multiple programs and wait for their windows to appear.
|
||||
Once these windows appeared a custom i3 command can be specified.
|
||||
|
||||
Run only one program.
|
||||
|
||||
### Config
|
||||
|
||||
Run multiple programs by specifying a yaml configuration file:
|
||||
## Example
|
||||
|
||||
```yaml
|
||||
---
|
||||
signal: signal number or name, optional. Should program entries which have signal: true wait for this signal before continuing to the next one.
|
||||
timeout: timeout in milliseconds
|
||||
init: a lisp program, optional. Used to initialize the environment, useful to define custom functions which should be available everywhere.
|
||||
programs:
|
||||
- match: a filter with which to match the window
|
||||
workspace: string or null, the workspace to move windows to
|
||||
cmd: string or list, the command to execute
|
||||
signal: boolean, should we wait before continuing with the next entry
|
||||
timeout: timeout in milliseconds, used only if signal: true - how long to wait for the signal
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
## 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`.
|
||||
|
||||
## Filtering
|
||||
|
||||
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).
|
||||
|
||||
In order to move the correct window to the desired workspace a filter can be defined.
|
||||
|
||||
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.
|
||||
|
||||
It is then possible to construct a filter for any program.
|
||||
|
||||
Available Operators:
|
||||
|
||||
- and: `&`: logical and, ungreedy
|
||||
- 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"))`
|
||||
|
||||
For example: `(> (load ".container.geometry.width") 300)` would match the first window where the width is greater than 300.
|
||||
|
||||
Multiple filters are combined via nesting: `(& (> (load ".container.geometry.width") 300) (= (load ".container.window_properties.class") "discord"))`.
|
||||
|
||||
## Starting tray programs in a specific order
|
||||
|
||||
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.
|
||||
|
||||
This could be combined with waybar to enforce an ordering of tray applications:
|
||||
|
||||
`~/.config/waybar/config`
|
||||
```json
|
||||
"tray": {
|
||||
"on-update": "pkill --full --signal SIGUSR1 i3toolwait",
|
||||
"reverse-direction": true,
|
||||
}
|
||||
```
|
||||
|
||||
`config-file`
|
||||
```yaml
|
||||
signal: SIGUSR1
|
||||
timeout: 2000
|
||||
timeout: 10000
|
||||
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))
|
||||
(begin
|
||||
(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:
|
||||
- cmd: 'nm-applet --indicator'
|
||||
match: '(False)'
|
||||
timeout: 1000
|
||||
signal: true
|
||||
- cmd: 'blueman-applet'
|
||||
match: '(False)'
|
||||
timeout: 1000
|
||||
signal: true
|
||||
- ...
|
||||
- run: 'exec gtk-launch librewolf'
|
||||
cmd: 'for_window [con_id="{result}"] focus; move container to workspace 1'
|
||||
match: '(match-load "LibreWolf")'
|
||||
- run: 'exec gtk-launch nheko || gtk-launch io.element.Element'
|
||||
cmd: 'for_window [con_id="{result}"] focus; move container to workspace 2'
|
||||
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'
|
||||
```
|
||||
|
||||
This setup would order the icons in waybar from left-to-right like in the config file.
|
||||
## Configuration
|
||||
|
||||
## Troubleshooting
|
||||
The configuration file is in YAML format.
|
||||
|
||||
### My windows do not get rearranged
|
||||
|
||||
It is very likely that the timeout is too short and the program exits before the window spawns.
|
||||
Alternatively your filter might just be wrong. To debug execute the script with the `--debug`
|
||||
flag to see if the window is recognized.
|
||||
### Configuration
|
||||
|
||||
#### timeout: int
|
||||
|
||||
_Optional_ _Default_ `3000`
|
||||
|
||||
Total program timeout in ms.
|
||||
|
||||
#### init: String
|
||||
|
||||
_Optional_ _Default_ `""`
|
||||
|
||||
Initialization program; Used to initialize the environment, useful
|
||||
to define custom functions which should be available everywhere.
|
||||
|
||||
#### cmd: String
|
||||
|
||||
_Optional_ _Default_ `""`
|
||||
|
||||
A final i3 command to be executed before exiting.
|
||||
|
||||
#### programs: List[Union[[Program](#program), [Signal](#signal)]]
|
||||
|
||||
_Optional_ _Default_ `[]`
|
||||
|
||||
A list of programs to execute.
|
||||
|
||||
### Program
|
||||
|
||||
Launch all programs using [`run`](#run-string) and execute
|
||||
[`cmd`](#cmd-string-1) once [`match`](#match-string) matches
|
||||
a window.
|
||||
|
||||
#### match: String
|
||||
|
||||
_Required_
|
||||
|
||||
A lisp program which analyzes the i3 window event and returns a value.
|
||||
If the return value is `false` the window does not match and no
|
||||
further processing occurs. Otherwise the i3 command
|
||||
[`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.
