• CLI: Run via the command line with unit support for kg/lbs and cm/in.
• TUI: Interactive text-based UI using tview.
• Web Interface: Simple web version built with Gin framework, offering a user-friendly web form.
• Versioning: Display version info using --version.
• Unit Testing: Built-in tests using Go’s testing framework.

• Go 1.23 or newer

1. Clone the repository:

git clone https://github.com/k1lgor/bmi cd bmi

2. Install dependencies (for TUI and Web):

go get github.com/rivo/tview go get github.com/gin-gonic/gin

3. Build the project:

go build -o bmi ./cmd/bmi

• CLI

./bmi 70 kg 170 cm

• TUI

./bmi -tui

• Web

./bmi -web

Then open your browser at http://localhost:8080.

• Version

./bmi -version

You can run the BMI app in a container without installing Go:

# Build the image docker build -t bmi . # CLI mode docker run --rm bmi 70 kg 170 cm # Web mode (visit http://localhost:8080) docker run --rm -p 8080:8080 bmi --web # TUI mode (interactive terminal) docker run -it --rm bmi --tui
