Scalapy completion dev

[kiendang]

This PR adds completion support for ScalaPy in ammonite. It is not to be merged into ammonite as is but ideally waits till ammonite has support for completion extension

How to try this out

build an executable from this branch

./mill "amm[2.13.6].assembly"

run ammonite

java -jar out/amm/2.13.6/assembly/dest/out.jar

inside the repl, set up ScalaPy

import $ivy.`ai.kien::python-native-libs:0.2.1`
import $ivy.`me.shadaj::scalapy-core:0.5.0+8-7c7a6042`

import ai.kien.python.Python

Python().scalapyProperties.fold(
  ex => println(s"Error while getting ScalaPy properties: $ex"),
  props => props.foreach { case(k, v) => System.setProperty(k, v) }
)

import me.shadaj.scalapy.py
import me.shadaj.scalapy.py.PyQuote
import me.shadaj.scalapy.interpreter.CPythonInterpreter

Features

Basic completion is provided by the standard library rlcompleter, more advanced completion is available if jedi is installed.

Basic completion

This provides completion for attributes only

@ py.Dynamic.global.li|
license( list(

@ val v = py"'string'"
@ v.up|
upper(

@ Object Obj { val v = py"'string'" }
@ Obj.v.up|
upper(

@ CPythonInterpreter.execManyLines("class Cls(): x = 'string'")
@ py.Dynamic.global.Cls.x.up|
upper(

Things like py.Dynamic.global.range(10).cou| won't work

Jedi completion

This has support for more advanced completion thanks to jedi static analysis

@ py.Dynamic.global.range(10).cou|
count|
