Formats

The editor is an event machine which produces events and consumes different inputs to produce a final output - what you see on the screen. Actions are just modifications of inputs from one stage to another. In this paradigm it is paramount to agree on the format of input, how different steps will process their inputs and produce output that validates as the input to the next step.

Displaying text on the screen

A data structure to display the text on the screen. Work in progress, we will start simple and progress from there.

Just text

Some form of structured text that is divided by lines.

{
    lines: [
        {
            number: 1,
            contents: "Hello"
        },
        {
            number: 2,
            contents: "world!"
        }
    ]
}

Text with style

This time text can have styles.

{
    lines: [
        {
            number: 1,
            segments: [
                {
                    contents: "Hello",
                    style: {
                        foreground: "default",
                        background: "default",
                        font_style: 0, // int-encoded styles: BOLD | ITALIC
                    }
                }
            ]
        },
        {
            number: 2,
            segments: [
                {
                    contents: "w",
                    style: {
                        foreground: "red",
                        background: "default",
                        font_style: 0
                    }
                },
                {
                    contents: "o",
                    style: {
                        foreground: "green",
                        background: "default",
                        font_style: 0
                    }
                },
                {
                    contents: "rld!",
                    style: {
                        foreground: "blue",
                        background: "default",
                        font_style: 0
                    }
                }
            ]
        }
    ]
}
