## InfiniTime Daemon
|
|
|
|
`itd` is a daemon that uses my infinitime [library](https://go.arsenm.dev/infinitime) to interact with the [PineTime](https://www.pine64.org/pinetime/) running [InfiniTime](https://infinitime.io).

### Socket
|
|
|
|
This daemon creates a UNIX socket at `/tmp/itd/socket`. It allows you to directly control the daemon and, by extension, the connected watch.
|
|
|
|
The socket accepts JSON requests. For example, sending a notification looks like this:
|
|
|
|
```json
|
|
{"type": "notify", "data": {"title": "title1", "body": "body1"}}
|
|
```
|
|
|
|
It will return a JSON response. A response can have 3 fields: `error`, `msg`, and `value`. Error is a boolean that signals whether an error was returned. If error is true, the msg field will contain the error. Value can contain any data and depends on what the request was.
|
|
|
|
The various request types and their data requirements can be seen in `internal/types`. I can make separate docs for it if I get enough requests.
|

### Transliteration
|
|
|
|
Since the PineTime does not have enough space to store all unicode glyphs, it only stores the ASCII space and Cyrillic. Therefore, this daemon can transliterate unsupported characters into supported ones. Since some languages have different transliterations, the transliterators to be used must be specified in the config. Here are the available transliterators:
|
|
|
|
- eASCII
|
|
- Scandinavian
|
|
- German
|
|
- Hebrew
|
|
- Greek
|
|
- Russian
|
|
- Ukranian
|
|
- Arabic
|
|
- Farsi
|
|
- Polish
|
|
- Lithuanian
|
|
- Estonian
|
|
- Icelandic
|
|
- Czeck
|
|
- French
|
|
- Armenian
|
|
- Korean
|
|
- Chinese
|
|
- Emoji
|
|
|
|
Place the desired map names in an array as `notifs.translit.use`. They will be evaluated in order. You can also put custom transliterations in `notifs.translit.custom`. These take priority over any other maps. The `notifs.translit` config section should look like this:
|
|
|
|
```toml
|
|
[notifs.translit]
|
|
use = ["eASCII", "Russian", "Emoji"]
|
|
custom = [
|
|
"test", "replaced"
|
|
]
|
|
```
|
|

### `itctl`
|
|
|
|
This daemon comes with a binary called `itctl` which uses the socket to control the daemon from the command line. As such, it can be scripted using bash.
|
|
|
|
This is the `itctl` usage screen:
|
|
```
|
|
Control the itd daemon for InfiniTime smartwatches
|
|
|
|
Usage:
|
|
itctl [command]
|
|
|
|
Available Commands:
|
|
completion generate the autocompletion script for the specified shell
|
|
firmware Manage InfiniTime firmware
|
|
get Get information from InfiniTime
|
|
help Help about any command
|
|
notify Send notification to InfiniTime
|
|
set Set information on InfiniTime
|
|
|
|
Flags:
|
|
-h, --help help for itctl
|
|
|
|
Use "itctl [command] --help" for more information about a command.
|
|
```
|

### `itgui`
|
|
|
|
In `cmd/itgui`, there is a gui frontend to the socket of `itd`. It uses the [fyne library](https://fyne.io/) for Go. It can be compiled by running:
|
|
|
|
```shell
|
|
go build ./cmd/itgui
|
|
```

#### Interactive mode
|
|
|
|
Running `itctl` by itself will open interactive mode. It's essentially a shell where you can enter commands. For example:
|
|
|
|
```
|
|
$ itctl
|
|
itctl> fw ver
|
|
1.3.0
|
|
itctl> get batt
|
|
81%
|
|
itctl> get heart
|
|
92 BPM
|
|
itctl> set time 2021-08-22T00:06:18-07:00
|
|
itctl> set time now
|
|
itctl> exit
|
|
```
|

### Installation
|
|
|
|
To install, install the go compiler and make. Usually, go is provided by a package either named `go` or `golang`, and make is usually provided by `make`. The go compiler must be version 1.16 or newer for the `io/fs` module.
|
|
|
|
To install, run
|
|
```shell
|
|
make && sudo make install
|
|
```
|
|
|

|
|
|
|
### Starting
|
|
|
|
To start the daemon, run the following **without root**:
|
|
|
|
```shell
|
|
systemctl --user start itd
|
|
```
|
|
|
|
To autostart on login, run:
|
|
```shell
|
|
systemctl --user enable itd
|
|
```
|
|
|
|
---
|
|
|
|
### Cross compiling
|
|
|
|
To cross compile, simply set the go environment variables. For example, for PinePhone, use:
|
|
|
|
```shell
|
|
make GOOS=linux GOARCH=arm64
|
|
```
|
|
|
|
This will compile `itd` and `itctl` for Linux aarch64 which is what runs on the PinePhone. This daemon only runs on Linux due to the library's dependencies (`dbus`, `bluez`, and `playerctl` specifically).
|
|
|

|
|
|
|
### Configuration
|
|
|
|
This daemon places a config file at `/etc/itd.toml`. This is the global config. `itd` will also look for a config at `~/.config/itd.toml`.
|
|
|
|
Most of the time, the daemon does not need to be restarted for config changes to take effect. |
