Simple Calculator

Hey, thanks for the awesome tool.

I constantly need to make some simple calculations and that's one of a feature that I liked about Alfred.

With ScriptKit I think I made it slightly better:

• live preview of your calculation
• select to copy to clipboard
• remembers last 10 calculations
• auto fixing , to . - so you don't have to do it manually

const calcDb = db('calc', {history: []});

function createResult(calculationResult, input) {
    return {name: calculationResult, description: input, value: {calculationResult, input}}
}

const {calculationResult, input, ...rest} = await arg("calculate:", async (input) => {
    const choices = [];

    if (input) {
        choices.push(createResult((await exec(`bc <<<"${input.replace(/\,/g, ".")}" -l`)).replace(/^\./, "0."), input))
    }

    return choices.concat(calcDb.get('history').value())
})

if (calculationResult) {
    const history = calcDb.get('history').value();

    history.unshift(createResult(calculationResult, input));

    calcDb.set('history', history.filter(({description}, index) => index === 0 || description !== input).slice(0, 10)).write()
}

copy(calculationResult)
