Weird companion object issue in Scala 2.11 vs 2.12
case class Country(name: String) {
private val ThreeLetterValidCountries = List("FOO", "BAR")
def valid: Option[Country] =
if (ThreeLetterValidCountries.contains(name.toUpperCase)) Some(this) else None
}
object Country {

Converts a DataFrame schema output (StructType) into something you can paste as a schema, as valid Scala code. Useful when working with Apache Zeppelin or any other REPL.
import org.apache.spark.sql.types._ // You'll need this to evaluate its output
object StructFmt {
def asScala(field: StructField): String = field.dataType match {
case struct: StructType => s"""StructField("${field.name}",""" + asScala(struct) + s", ${field.nullable})"
case _ => s"""StructField("${field.name}", ${field.dataType}, ${field.nullable})"""
}
def asScala(struct: StructType): String = "StructType(Seq(" + (for(field <- struct) yield asScala(field)).mkString(",") + "))"
}

rberenguel / fun_with_ast.py
Last active January 8, 2017 17:57
Having some quick fun with the ast (and being really impressed by how grumpy (https://github.com/google/grumpy/tree/master/compiler) manages to do it so neatly for python-go, this is a quick hack to play with ast). Enters a simple (almost hardcoded for this example) class, outputs a scala-valid class that you can try on an interpreter.
from __future__ import print_function
import ast
"""
Save the following in test.py, then execute fun_with_ast.py.
You can paste the output in a Scala interpreter
class something(object):
def __init__(self, value1, value2):
