Rules for particular applications can be kept in files of their own, applications.json, which komorebi.json names with app_specific_configuration_path: one path or a list. The ignore, manage and floating rules of every application in a file are added to the lists the configuration's own rules go in, so a file can be shared or kept apart from the settings. A path with no file behind it is skipped with a warning, since one komorebi.json is meant to work on every platform and may name a file that only another platform has; a file that is there and is not an applications.json is an error. The titleless and tabbed rules of other platforms are read and do nothing. komorebic/applications.json is a start for Plasma: it floats the calculators, the screenshot tool, the authentication dialog and System Settings. A test opens the windows it names.

# Application specific configuration
|
|
|
|
Some applications need to be told how to behave under a tiling window manager: a calculator that
|
|
should float instead of taking a tile, a launcher that should never be tiled. The
|
|
[rules](rules.md) that say so can be put in `komorebi.json`, or in a file of their own,
|
|
`applications.json`, that the configuration names. The file can be shared, or kept apart from
|
|
the settings, and a list of files can be put together from several sources.
|
|
|
|
## The file
|
|
|
|
`applications.json` is an object with one entry for each application. The name of the entry is
|
|
only for the reader. Each entry has lists of [rules](rules.md), as `komorebi.json` has them:
|
|
|
|
```json
|
|
{
|
|
"KDE Plasma": {
|
|
"floating": [
|
|
{ "kind": "Class", "id": "org.kde.kcalc", "matching_strategy": "Equals" },
|
|
{ "kind": "Class", "id": "org.kde.spectacle", "matching_strategy": "Equals" }
|
|
]
|
|
},
|
|
"Steam": {
|
|
"ignore": [{ "kind": "Exe", "id": "steam", "matching_strategy": "Equals" }]
|
|
}
|
|
}
|
|
```
|
|
|
|
| List | What it does | In `komorebi.json` |
|
|
|---|---|---|
|
|
| `ignore` | komorebi leaves the windows alone | `ignore_rules` |
|
|
| `manage` | komorebi tiles the windows, whatever the ignore rules say | `manage_rules` |
|
|
| `floating` | the windows open floating | `floating_applications` |
|
|
| `titleless`, `tabbed` | nothing: they work around how another platform exposes windows, and a KWin window is always a window | `titleless_applications`, `tabbed_applications` |
|
|
|
|
An entry named `$schema` has the address of a schema as its value, as an editor wants it, and
|
|
is ignored.
|
|
|
|
## Naming the file
|
|
|
|
`app_specific_configuration_path` in `komorebi.json` is the path of one file, or a list of paths:
|
|
|
|
```json
|
|
{
|
|
"app_specific_configuration_path": "$HOME/.config/komorebi/applications.json"
|
|
}
|
|
```
|
|
|
|
```json
|
|
{
|
|
"app_specific_configuration_path": [
|
|
"$HOME/.config/komorebi/applications.json",
|
|
"$HOME/.config/komorebi/mine.json"
|
|
]
|
|
}
|
|
```
|
|
|
|
Environment variables in a path, such as `$HOME`, are replaced. The files are read when
|
|
`komorebi.json` is: when the daemon starts, and again when the configuration changes. Their rules
|
|
are added to the ones the daemon has, after the rules of `komorebi.json` itself, which
|
|
[Configuration](configuration.md#rules) explains.
|
|
|
|
A path with no file behind it is skipped, and the daemon logs a warning: one `komorebi.json` can
|
|
serve every platform, even if it names a file that only another platform has. A file that is
|
|
there and is not an `applications.json`, or has a rule that is not valid, is an error: the daemon
|
|
does not start with it, and a reload with it fails and logs the error. Only a file with the
|
|
extension `.json` is read.
|
|
|
|
## The file komorebi ships
|
|
|
|
[`komorebic/applications.json`](../../komorebic/applications.json) in the repository has an
|
|
entry for KDE Plasma, which floats the calculators of KDE and GNOME, the screenshot tool, the
|
|
authentication dialog of Plasma and System Settings. A test loads it, and opens the windows it
|
|
names.
