From 7ce52c4a7a07b0db5e7c1312b1920efb1165ce6a Mon Sep 17 00:00:00 2001 From: Aaron Davidson Date: Sun, 6 Apr 2014 17:43:44 -0700 Subject: SPARK-1349: spark-shell gets its own command history Currently, spark-shell shares its command history with scala repl. This fix is simply a modification of the default FileBackedHistory file setting: https://github.com/scala/scala/blob/master/src/repl/scala/tools/nsc/interpreter/session/FileBackedHistory.scala#L77 Author: Aaron Davidson Closes #267 from aarondav/repl and squashes the following commits: f9c62d2 [Aaron Davidson] SPARK-1349: spark-shell gets its own command history separate from scala repl --- .../main/scala/org/apache/spark/repl/SparkJLineReader.scala | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'repl/src') diff --git a/repl/src/main/scala/org/apache/spark/repl/SparkJLineReader.scala b/repl/src/main/scala/org/apache/spark/repl/SparkJLineReader.scala index 946e710390..0db26c3407 100644 --- a/repl/src/main/scala/org/apache/spark/repl/SparkJLineReader.scala +++ b/repl/src/main/scala/org/apache/spark/repl/SparkJLineReader.scala @@ -7,8 +7,10 @@ package org.apache.spark.repl +import scala.reflect.io.{Path, File} import scala.tools.nsc._ import scala.tools.nsc.interpreter._ +import scala.tools.nsc.interpreter.session.JLineHistory.JLineFileHistory import scala.tools.jline.console.ConsoleReader import scala.tools.jline.console.completer._ @@ -25,7 +27,7 @@ class SparkJLineReader(_completion: => Completion) extends InteractiveReader { val consoleReader = new JLineConsoleReader() lazy val completion = _completion - lazy val history: JLineHistory = JLineHistory() + lazy val history: JLineHistory = new SparkJLineHistory private def term = consoleReader.getTerminal() def reset() = term.reset() @@ -78,3 +80,11 @@ class SparkJLineReader(_completion: => Completion) extends InteractiveReader { def readOneLine(prompt: String) = consoleReader readLine prompt def readOneKey(prompt: String) = consoleReader readOneKey prompt } + +/** Changes the default history file to not collide with the scala repl's. */ +class SparkJLineHistory extends JLineFileHistory { + import Properties.userHome + + def defaultFileName = ".spark_history" + override protected lazy val historyFile = File(Path(userHome) / defaultFileName) +} -- cgit v1.2.3
