TUI implementation in Go of 7GUIs task

See https://eugenkiss.github.io/7guis/tasks for the descriptions of each task.

About

• This project is for learning tview and building TUI apps only. The code is neither optimized nor truely correct.

• Keyboard shortcuts navigation is pretty non-standard. Please don't expect Tab, Shift-Tab and work as usual. Most of the time, Tab and Shift-Tab switch betweent the sidebar and the widget view. Mouse control should works as expected (albeit rather laggy) for input fields, slider and buttons.

Run

This project requires go version 1.13 or higher to use go modules. If you clone the source locally, then just run it via:

$ go run .

If you have go1.17 or higher, which support install command, you can install the demo and run via:

$ go install github.com/letientai299/7guis/tui@latest
$ tui

The application is not supposed to be useful, so, you might want to remove the installed binary after play around with it.

$ rm $GOPATH/bin/tui

Developing tips

For quick edit and review loop, use nodemon to watch for code change, rebuild and restart the application via:

$ nodemon -w . -e .go -x './restart.sh'

Lesson learned

• tview.Form overrides each input fields style. Hence, after Temperature Converter, for other form component, I rather use the field directly to support color changes during validation.

• tview doesn't have a reactive system, hence, it's very painful to implement these exercises in it. Or, perhaps I'm just too stupid to figure out the correct way to implement them.
