Going forward for new installations, config and data files will be
stored at the platform default paths, as defined by
[env-paths](https://www.npmjs.com/package/env-paths).
For backwards compatibility, if the `~/.waveterm` or `WAVETERM_HOME`
directory exists and contains valid data, it will be used. If this check
fails, then `WAVETERM_DATA_HOME` and `WAVETERM_CONFIG_HOME` will be
used. If these are not defined, then `XDG_DATA_HOME` and
`XDG_CONFIG_HOME` will be used. Finally, if none of these are defined,
the [env-paths](https://www.npmjs.com/package/env-paths) defaults will
be used.
As with the existing app, dev instances will write to `waveterm-dev`
directories, while all others will write to `waveterm`.
Adds new functionality on the backend that will merge any file from the
config directory that matches `<partName>.json` or `<partName>/*.json`
into the corresponding config part (presets, termthemes, etc.). This
lets us separate the AI presets into `presets/ai.json` so that we can
add a dropdown in the AI preset selector that will directly open the
file so a user can edit it more easily. Right now, this will create a
preview block in the layout, but in the future we can look into making
this block disconnected from the layout.
If you put AI presets in the regular presets.json file, it will still
work, since all the presets get merged. Same for any other config part.
json.Unmarshal parses all numbers to float64, which breaks any integer
settings values. This PR changes MetaSettingsType.UnmarshalJSON to use
json.Decoder, which is capable of parsing into a meta-type json.Number,
which can be interpreted as a float or an integer. It also properly
handles pointer types.
This migrates all remaining eventbus events sent over the websocket to
use the wps interface. WPS is more flexible for registering events and
callbacks and provides support for more reliable unsubscribes and
resubscribes.
The frontend wshserver.ts had a weird circuitous dependency on wos.ts,
which was unnecessary. This moves the misplaced functions into wshrpc.ts
and updates the generation logic.
Fixes an infinite loop in the layoutModel atom synchronization that
would cause the atom to update indefinitely when the root node is
deleted.
Also adds a dedicated `disabled` flag for the IconButton decl so we can
disable the onClick handler when the button is disabled.
Also updates the Magnify toggle button to use this new flag, so that
when there's only one leaf in a layout, the magnify button is disabed.
