# ketotrack
Simple GKI calculator written as an exercise in learning Go.

Currently, this only calculates your GKI and stores the results into a JSON file. At some point I'll get around to
implementing note-taking and time-series display.

## Usage
After measuring your blood glucose and blood ketone levels, run `ketotrack`. GKI will be displayed along with
the level of ketosis you are in according to [Keto-Mojo](https://keto-mojo.com/glucose-ketone-index-gki/):
```
Enter glucose reading (mg/dL): 77
Enter ketone reading (mmol/L): 1.1

Your GKI is: 3.89
You're in a moderate level of ketosis.
```

Reading data will be saved to `$HOME/.ketotrack/readings.json`.

## Building and Installing
```shell
go build
mv ketotrack $HOME/.local/bin
```

## Refactoring Notes
- [X] Create `Record` and `Note` struct types
- [X] Add `GKI` field to `Reading` struct type
- [X] Encapsulate application data with an `AppContext` struct that holds a `Records` slice
  - [X] `LoadRecords`, `SaveRecords`, `AddReading`, `AddNote` receiver methods
- [X] Add interactive menu for adding either a `Note` or a `Record`
- [ ] Standardize method names for getting user input to `handleNewNote` and `handleNewReading`
