## Features
Handle [Pinescript] using [Python]
- Parse Pinescript code into AST
- Dump parsed AST
- Unparse parsed AST back to Pinescript code
Given an example pinescript with name of `rsi_strategy.pine`:
```pinescript
//@version=5
strategy("RSI Strategy", overlay=true)
length = input( 14 )
overSold = input( 30 )
overBought = input( 70 )
price = close
vrsi = ta.rsi(price, length)
co = ta.crossover(vrsi, overSold)
cu = ta.crossunder(vrsi, overBought)
if (not na(vrsi))
if (co)
strategy.entry("RsiLE", strategy.long, comment="RsiLE")
if (cu)
strategy.entry("RsiSE", strategy.short, comment="RsiSE")
//plot(strategy.equity, title="equity", color=color.red, linewidth=2, style=plot.style_areabr)
```
Parsing script into AST and dumping it:
```console
$ pynescript parse-and-dump rsi_strategy.pine
```
Gives like:
```python
Script(
body=[
Expr(
value=Call(
func=Name(id='strategy', ctx=Load()),
args=[
Arg(
value=Constant(value='RSI Strategy')),
Arg(
value=Constant(value=True),
name='overlay')])),
Assign(
target=Name(id='length', ctx=Store()),
value=Call(
func=Name(id='input', ctx=Load()),
args=[
Arg(
value=Constant(value=14))]),
annotations=[]),
...
```
<details>
<summary>Full AST dump that is quite long...</summary>

```
</details>
Parsing into AST and unparsing it back:
```console
$ pynescript parse-and-unparse rsi_strategy.pine
```
Gives (with some difference in syntax including spacing):
```pinescript
//@version=5
strategy("RSI Strategy", overlay=true)
length = input(14)
overSold = input(30)
overBought = input(70)
price = close
vrsi = ta.rsi(price, length)
co = ta.crossover(vrsi, overSold)
cu = ta.crossunder(vrsi, overBought)
if not na(vrsi)
if co
strategy.entry("RsiLE", strategy.long, comment="RsiLE")
if cu
strategy.entry("RsiSE", strategy.short, comment="RsiSE")
```
