This PR adds the ability for icon themes to provide their own file
associations.
The old `file_types.json` that was previously used to make these
associations has been removed in favor of storing them on the default
theme.
Icon themes have two new fields on them:
- `file_stems`: A mapping of file stems to icon keys.
- `file_suffixes`: A mapping of file suffixes to icon keys.
These mappings produce icon keys which can then be used in `file_icons`
to associate them to a particular icon:
```json
{
"file_stems": {
"Makefile": "make"
},
"file_suffixes": {
"idr": "idris"
},
"file_icons": {
"idris": { "path": "./icons/idris.svg" },
"make": { "path": "./icons/make.svg" }
}
}
```
When loading an icon theme, the `file_stems` and `file_icons` fields
will be merged with the ones from the base icon theme, with the values
from the icon theme being loaded overriding ones in the base theme.
Release Notes:
- Added the ability for icon themes to provide their own file
associations.
This PR adds the supporting infrastructure to support loading icon
themes defined by extensions.
Here's an example icon theme:
```json
{
"name": "My Icon Theme",
"author": "Me <me@example.com>",
"themes": [
{
"name": "My Icon Theme",
"appearance": "dark",
"file_icons": {
"gleam": { "path": "./icons/file_type_gleam.svg" },
"toml": { "path": "./icons/file_type_toml.svg" }
}
}
]
}
```
The icon paths are resolved relative to the root of the extension
directory.
Release Notes:
