Missing enum `extend`

[dcaoyuan]

Test case:

//@version=5
indicator("AAPL Dynamic Line Analysis", overlay=true)

// Find Pivots for Lines
p_len = 10
ph = ta.pivothigh(high, p_len, p_len)
pl = ta.pivotlow(low, p_len, p_len)

// Using line.new for Trendlines
var line trend_down = na
var line trend_up = na

// Downward Trendline
float ph1 = ta.valuewhen(ph, high[p_len], 0)
float ph2 = ta.valuewhen(ph, high[p_len], 1)
int ph1_idx = ta.valuewhen(ph, bar_index[p_len], 0)
int ph2_idx = ta.valuewhen(ph, bar_index[p_len], 1)

if not na(ph)
    line.delete(trend_down)
    trend_down := line.new(ph2_idx, ph2, ph1_idx, ph1, color=color.red, width=2, xloc=xloc.bar_index, extend=extend.right)

// Upward Trendline
float pl1 = ta.valuewhen(pl, low[p_len], 0)
float pl2 = ta.valuewhen(pl, low[p_len], 1)
int pl1_idx = ta.valuewhen(pl, bar_index[p_len], 0)
int pl2_idx = ta.valuewhen(pl, bar_index[p_len], 1)

if not na(pl)
    line.delete(trend_up)
    trend_up := line.new(pl2_idx, pl2, pl1_idx, pl1, color=color.green, width=2, xloc=xloc.bar_index, extend=extend.right)

// Horizontal Support/Resistance via line
if not na(ph)
    line.new(bar_index[p_len], ph1, bar_index + 10, ph1, color=color.new(color.red, 50), width=1, style=line.style_dashed)

if not na(pl)
    line.new(bar_index[p_len], pl1, bar_index + 10, pl1, color=color.new(color.green, 50), width=1, style=line.style_dashed)

plot(close, color=na)

Will encounter:

extend is not defined

Merged, please note that I will change it to this, in order to match Pine Script internal representation

export enum extend {
    left = 'l',
    right = 'r',
    both = 'b',
    none = 'n',
}

there are also some other impacted types like belowbar, abovebar becoming BelowBar, AboveBar
and arrowup, arrowdown becoming shape_arrow_up, shape_arrow_down ...etc

I changed many Type enums values to match internal tradingview representation

In tradingview you can get the actual representations by using a code like this :

log.info('{0} {1} {2} {3} {4} {5}', str.tostring(location.abovebar), str.tostring(location.belowbar), str.tostring(location.top), str.tostring(location.bottom), str.tostring(location.absolute))
