RegexParsers: skipWhitespaces when using implicit conversion from a character

2

(I wanted to lower the priority of this issue, but somehow wasn't allowed to do so in the bug filing form) A RegexParsers parser should skip whitespaces. It does so...

PackratParsers and RegexParsers / JavaTokenParsers don't work well in combination

2

We have a parser that inherits from both `JavaTokenParsers` and `PackratParsers`; and it turns out that the `.parse()` method that the former provides (via `RegexParsers`) is incompatible with the latter....

Case insensitive regexs in parser combinators

4

Hi, The `scala.util.parsing.combinator` library should provide a way of turning on case insensitive matches; having to prefix every string with a (?i) isn't ideal. E.g., `"""(?iu)\|H""".r`, just ends up cluttering...

JavaTokenParsers stringLiteral Unicode literals not fully correct

2

The stringLiteral function in scala.util.parsing.combinator.!JavaTokenParsers tries to parse String literals with Unicode escape sequence in them ```scala def stringLiteral: Parser[String] = ("\""+"""([^"\p{Cntrl}\\]|\\[\\/bfnrt]|\\u[a-fA-F0-9]{4})*"""+"\"").r ``` However, such Unicode escapes can occur elsewhere,...

Add ability to defined new parser combinators

2

The current parser combinators library is flexible but lacks the ability to easily define new combinators. For example, in a grammar that supports JavaTokensParser.wholeNumber and JavaTokensParser.floatingPointNumber literals and an e...

Parser combinator framework consumes unnececessary amount of memory

2

Since all Readers provider by parser combinators framework use PagedSeq inside, using those parsers for working with large files seems impossible - because PagedSeq will not release already parsed elements....

java annotation and reflection: "illegal cyclic reference involving object InterfaceAudience"

15

See attached exception traces. With Scala 2.11.8 and Hadoop CDH v5.4, calling `typeOf` on a type annotated with the Hadoop `InterfaceAudience` annotation causes a `scala.reflect.internal.Symbols$CyclicReference: illegal cyclic reference involving object...

The following code snipet : https://gist.github.com/1427587 does not compile. ```scala import java.util.Date trait TDate trait TT[A1,T1] trait TTFactory[F,G] { def create(f: F) : TT[F,G] def sample: F } object Impls...

Allow named and default arguments in pattern matching

18

Named and default arguments have been introduced in Scala 2.8, and were outlined in [SIP #1](https://docs.scala-lang.org/sips/named-and-default-arguments.html). An important scenario has been overlooked in the SIP, which is to define interaction...

scalac reports error on valid Java class: illegal cyclic reference involving type T

17

When compiling a mix of Java and Scala files, scalac will report an error on otherwise valid Java files. To reproduce, create 2 files: Foo.java: ```java public class Foo
