Pull requests are very welcome! Here some open todo items:
Pull requests are very welcome, feel free to open an issue! Here some open todo items:
- [x] Manage workspace state across multiple nvim instances (e.g. tmux)
- [x] Set activity on other autocommands (`TextChanged`, `VimLeavePre`)
- [ ] Set idle activity (track using `CursorMoved`)
- [ ] Use named pipes to support Windows
- [ ] Expose file assets table as a configurable option
- [ ] Manage activity properly in buffers in windows and tabs
- [ ] Retry connection after initial setup or a closed pipe (i.e. after quitting Discord app)
- [ ] Attempt to connect to a range of pipes from `discord-ipc-0` to `discord-ipc-9` (see [note](https://github.com/discord/discord-rpc/blob/master/documentation/hard-mode.md#notes))
- [ ] Set activity on other autocommands (`:h events`)
Discord asset additions and changes are also welcome! Supported file types can be found in [file_assets.lua](lua/presence/file_assets.lua) and their assets can be found [in this folder](https://www.dropbox.com/sh/j8913f0gav3toeh/AADxjn0NuTprGFtv3Il1Pqz-a?dl=0).
