/*
  Introducing `f` – a simple formatter for complex strings
  optimized for readability, inspired by Python's printf

  ✅ No need for new variable names
  ✅ Readable code
  ✅ Readable result string
*/

//  Usage

pf`{paneler blir montert} {i uke} {21} ({26.} - {31. Oct})`(
  prefix,
  intl.formatMessage(m.installationDateInWeek),
  _startDate.week(),
  startOfWeek.format("Do"),
  endOfWeek.format("Do MMMM")
);


// Implementation

const f = ([str] = fistArg) => (...args) => {
  let counter = 0;
  const s = str.replace(/(\{[a-z\d\s\.]+\})/gi, () => {
    return args[counter++] || "";
  });
};




// Alternative approaches

/*
  Template literal approach: 

  ✅ No new variables
  ❌ Readable code
  ❌ Readable result string
*/

const inline = `${prefix} ${intl.formatMessage(
  m.installationDateInWeek
)} ${_startDate.week()} (${startOfWeekStartDate.format("Do")} –
      ${endOfWorkWeekEndDate.format("Do MMMM")})`;



/*
  2001 approach: 

  ✅ No new variables
  ✅ Readable code
  ❌ Readable result string
*/

const inline =
  prefix +
  " " +
  intl.formatMessage(m.installationDateInWeek) +
  " " +
  _startDate.week() +
  " (" +
  startOfWeekStartDate.format("Do") +
  " – " +
  endOfWorkWeekEndDate.format("Do MMMM") +
  ")";



/*
  Alternative approach with variables

  ❌ Have to come up with new variable names 
  ✅ Readable code
  ✅ Readable result string
*/

const installationDateInWeek = intl.formatMessage(m.installationDateInWeek);
const startWeek = _startDate.week();
const startDate = startOfWeekStartDate.format("Do");
const endDate = endOfWorkWeekEndDate.format("Do MMMM");
