Pinescript input line style

Question

I am new to pinescript and wrote this simple script to show me daily, weekly and monthly candle open lines by piecing together information I could find. This works well but I would like to add input options to change the line(s) width and style (dotted, dashed). Seems like an easy task, but somehow I can't figure it out. Could anybody help?

A bit more work but, my next step would be to be able to toggle an option where, after a period ends, the line would extend until it is crossed by price again. If there is an easy way to do this, I would be much grateful for any tips.

Thanks in advance!

//@version=6
indicator("D/W/M Open Lines", overlay=true, max_lines_count=500)
// === Input Options ===
showDaily = input.bool(true, title="Show Daily Open")
showWeekly = input.bool(true, title="Show Weekly Open")
showMonthly = input.bool(false, title="Show Monthly Open")
dailyColor = input.color(color.aqua, "Daily Line Color")
weeklyColor = input.color(color.yellow, "Weekly Line Color")
monthlyColor = input.color(color.fuchsia, "Monthly Line Color")
// === Line Variables ===
var line dailyLine = na
var line weeklyLine = na
var line monthlyLine = na
// === Daily Line Logic ===
dailyOpen = request.security(syminfo.tickerid, "D", open)
dailyTime = request.security(syminfo.tickerid, "D", time)
newDaily = dailyTime != dailyTime[1]
if showDaily
 if newDaily
 if not na(dailyLine)
 line.set_x2(dailyLine, x=dailyTime)
 dailyLine := line.new(x1=dailyTime, y1=dailyOpen, x2=time, y2=dailyOpen, color=dailyColor, extend=extend.none, xloc=xloc.bar_time)
 else if not na(dailyLine)
 line.set_x2(dailyLine, x=time)
// === Weekly Line Logic ===
weeklyOpen = request.security(syminfo.tickerid, "W", open)
weeklyTime = request.security(syminfo.tickerid, "W", time)
newWeekly = weeklyTime != weeklyTime[1]
if showWeekly
 if newWeekly
 if not na(weeklyLine)
 line.set_x2(weeklyLine, x=weeklyTime)
 weeklyLine := line.new(x1=weeklyTime, y1=weeklyOpen, x2=time, y2=weeklyOpen, color=weeklyColor, extend=extend.none, xloc=xloc.bar_time)
 else if not na(weeklyLine)
 line.set_x2(weeklyLine, x=time)
// === Monthly Line Logic ===
monthlyOpen = request.security(syminfo.tickerid, "M", open)
monthlyTime = request.security(syminfo.tickerid, "M", time)
newMonthly = monthlyTime != monthlyTime[1]
if showMonthly
 if newMonthly
 if not na(monthlyLine)
 line.set_x2(monthlyLine, x=monthlyTime)
 monthlyLine := line.new(x1=monthlyTime, y1=monthlyOpen, x2=time, y2=monthlyOpen, color=monthlyColor, extend=extend.none, xloc=xloc.bar_time)
 else if not na(monthlyLine)
 line.set_x2(monthlyLine, x=time)

More than one way to do it, this is my preferred method using enums.

//@version=6
indicator("My script", overlay = true)
enum lineStyle
 solid = 'Solid' 
 dashed = 'Dashed' 
 dotted = 'Dotted'
method styler(lineStyle this)=>
 switch this
 lineStyle.solid => line.style_solid
 lineStyle.dashed => line.style_dashed
 lineStyle.dotted => line.style_dotted
newLineStyle = input.enum(lineStyle.solid, title = ' ', inline = '1').styler()
if barstate.islast
 line.new(bar_index, high, bar_index + 5, high, style = newLineStyle)

You could also do it using a string input and a switch statement. Either way will get you the result you want

newLineStyle = input.string('Solid', 'Line Style', ['Solid', 'Dashed', 'Dotted'])
style = switch newLineStyle
 'Solid' => line.style_solid
 'Dashed' => line.style_dashed
 'Dotted' => line.style_dotted
if barstate.islast
 line.new(bar_index, high, bar_index + 5, high, style = style)
