Grizzled Scala Change Log

Version 4.11.0

  • grizzled.util.withResource is now implemented in terms of scala.util.Using.resource in 2.13 and in terms of a pared-down, backported version in 2.12 and 2.11. Similarly, grizzled.util.tryWithResource is implemented in terms of Using.apply. Both are marked @inline final.
  • From this version forward, this library is released under the Apache Software License, version 2. Prior versions are still under the 3-Clause BSD license. See for details.

Version 4.10.0

  • Now requires Java 1.8 or better. (Upgrade, already.)
  • grizzled.file.util.makeTemporaryDirectory() is deprecated. Use java.nio.file.Path.createTempDirectory(), instead.
  • Added grizzled.file.util.tryWithTemporaryDirectory(), which works like withTemporaryDirectory, except that it returns a Try instead of throwing or propagating exceptions.
  • Added a version of grizzled.file.util.copyTree that takes java.nio.file.Path arguments.
  • Added a version of grizzled.file.util.deleteTree that takes a java.nio.file.Path argument.
  • Added a version of grizzled.file.util.normalizePath that takes a java.nio.file.Path argument.

Version 4.9.3:

  • Upgraded to ScalaTest 3.0.8.
  • Now cross-compiles against Scala 2.13.0.

Version 4.9.2:

  • Merged in changes from @Philippus:
    • Updated Scala 2.13 to 2.13.0-RC1
    • Updaed various dependencies, including sbt-wartremover
    • Changed Long constants to use upper-case L, instead of deprecated lower-case l.
    • Replaced deprecated symbol literals.
    • Used explicit string conversion in some spots, to get past a wart-remover issue with interpolating non-string values.

Version 4.9.1:

  • Added grizzled.ScalaCompat.math.Ordering.Double.IeeeOrdering, grizzled.ScalaCompat.math.Ordering.Double.TotalOrdering, grizzled.ScalaCompat.math.Ordering.Float.IeeeOrdering, and grizzled.ScalaCompat.math.Ordering.Float.TotalOrdering, which map to their appropriate scala.math.Ordering counterparts for both 2.12 (and earlier) and 2.13 (and greater). This compatibility layer eliminates warnings in tester compilation.

Version 4.9.0:

  • Implemented a better way to handle compatibility between Scala 2.13 and earlier versions, one that requires less duplicate code, by providing appropriate type aliases in a new, conditionally-compiled grizzled.ScalaCompat package. Functions that use Stream in 2.12 and earlier still use LazyList in 2.13, but the implementation is better. Bumped the minor version, rather than the patch version, even though there aren't major API changes, because of the possible impact on compilation.

Version 4.8.0:

  • grizzled.file.util.listRecursively() and grizzled.file.Implicits.GrizzledFile.listRecursively() now return LazyList for Scala 2.13. They still return Stream for Scala 2.12 and earlier.
  • Various internal functions that used Stream have been tweaked to use LazyList for 2.13.

These changes necessitated some refactoring, as well as the introduction of src/main/pre-scala-2.13 and src/main/scala-2.13 directories to the source code, to contain parallel implementations.

Version 4.7.1:

  • Got rid of some of the 2.13.0 compiler deprecation warnings.

Version 4.7.0:

  • Removed support for Scala 2.10.
  • Updated to support Scala 2.13.0-M5 (with much help from @xuwei-k).
  • Updated ScalaTest dependency, to support Scala 2.13.0.
  • Updated various SBT plugins.

Version 4.6.0:

  • This release doesn't change anything, but marks the release of a 4.6.x branch for Scala 2.10-only. The 4.7.x series (and greater) will not support Scala 2.10. This branching is necessary because of changes in the Scala collections library in 2.13; the collections compatibility library isn't available for 2.10.

Version 4.5.1:

  • Change /: to foldLeft, since /: is deprecated in Scala 2.13. (Thanks to @xuwei-k for the patch.)

Version 4.5.0:

  • Merged PR #12, with fixes and performance improvements for, courtesy of @lespea.
  • Updated SBT to version 1.1.6.
  • Enabled Wart Remover and many, but not all, of its errors. Cleaned up offending code.
  • Various functions in grizzled.math and grizzled.math.stats (max(), min(), geometricMean(), etc.) now take one fixed parameter and a variable argument list, instead of just a variable argument list, to ensure that they are always called with at least one parameter.
  • grizzled.file.util functions no longer throw exceptions.

Version 4.4.2:

  • Fixed bug in grizzled.file.util.glob() that caused it to match non-existent files.
  • Added coursier to SBT.

Version 4.4.1:

  • Changed grizzled.datetime.EnhancedDuration to grizzled.datetime.EnrichedDuration, for consistency.

Version 4.4.0:

  • Added grizzled.datetime.EnhancedDuration class, with a humanize method that provides more human-readable string representations for Duration objects.
  • now extends AutoCloseable.

Version 4.3.0:

  • Added replaceFirstChar() to GrizzledString.
  • Added grizzled.file.util.longestCommonPathPrefix()
  • Updated version of Lightbend Activator.
  • Updated version of Scalatest.
  • Updated version of SBT.
  • Removed copyrights from some more source files, as they're hard to maintain.

Version 4.2.0:

  • Added RandomUtil.randomLongBetween().

Version 4.1.0:

  • Added grizzled.random.RandomUtil, containing some random number helper functions.
  • Changed grizzled.file.Includer to use a List, internally, rather than a Stack.
  • Added grizzled.datetime.DateTimeUtil, with a couple useful datetime-related functions.
  • Added grizzled.datetime.Implicits to provide enrichment classes for java.util.Date, java.util.Calendar and java.sql.Timestamp.
  • Removed custom matchers trait and scala.util.Try custom matcher in testers, in favor of ScalaTest's shouldBe 'success and shouldBe 'failure.

Version 4.0.0:

Contains breaking API changes.

  • Moved implicit evidence objects for CanReleaseResource into a sub-object (Implicits) within the CanReleaseResource companion, to alleviate confusion in Scala 2.12.0. They should be imported explicitly, not with a wildcard import, e.g., import grizzled.util.CanReleaseResource.Implicits.CanReleaseCloseable.
  • Added a CanReleaseResource evidence parameter for java.lang.AutoCloseable.

Version 3.1.0:

  • Built for Scala 2.12.0.
  • Fixed so that downloads don't bail with a java.nio.file.FileSystemNotFoundException for non-file URLs.

Version 3.0.0:

Contains breaking API changes.

  • Bumped cross-compiled build from Scala 2.12.0-M5 to 2.12.0-RC1.
  • Removed grizzled.either.Implicits.RichEither. The methods it contains are part of Either in Scala 2.12 (though are implemented somewhat differently).
  • The sub() method in grizzled.string.template.StringTemplate now returns a Try, instead of an Either.
  • grizzled.parsing.Pushback.pushback(List[T]) is now called pushbackMany().
  • Removed the following classes, which have been deprecated for some time:
    • grizzled.parsing.IteratorStream
    • grizzled.collection.MultiIterator
  • Removed the following methods/functions, which have deprecated for some time:
    • grizzled.parsing.Pushback.totalRead
    • grizzled.parsing.SafeIterator.totalRead.
    • grizzled.file.Implicits.GrizzledFile.walk
    • grizzled.sys.systemProperties

Version 2.8.0:

  • Added grizzled.file.util.joinAndNormalizePath, which combines the functionality of joinPath with that of normalizePath.
  • Fixed grizzed.file.util.deleteTree() to return successfully if the directory doesn't exist, instead of failing.

Version 2.7.0:

  • Added tryWithResource, a version of grizzled.util.withResource that returns a Try.
  • Upgraded to ScalaTest 3.0.0, release version.

Version 2.6.0:

  • Added an implicit mapWhile() function for use with collection types.
  • Un-deprecated grizzled.config.Configuration. It's still used by tools like AVSL
  • Corrected a bug in grizzled.file.Includer that prevented the final read from completing in certain circumstances.

Version 2.5.0:

  • Added grizzled.string.util.longestCommonPrefix().
  • Bumped cross-compiled build from Scala 2.12.0-M4 to 2.12.0-M5.
  • Upgraded ScalaTest to 3.0.0-RC4.

Version 2.4.2:

  • Fixed so that flattened zips don't end up with a spurious "." directory.

Version 2.4.1:

  • Deprecated grizzled.config.Configuration. If you need a good configuration file format, use YAML or HOCON.
  • Various fixes for Windows, including:
    • Changed various classes to use use the line.separator property, rather than a hard-coded "\n", when adding line terminators.
    • Changed how resolves parent directories.
  • Removed BrainDeadHTTPServer (used during testing) as it overly complicates testing. file: URLs are now used instead.

Version 2.4.0:

  • Removed use of asInstanceOf in and
  • Deprecated grizzled.collection.MultiIterator. It's not necessary: Use the Scala Iterator class's ++ operator to combine multiple iterators lazily.
  • Added tester for
  • Reimplemented grizzled.math.max() and grizzled.math.min() to work with any type for which there is an Ordering. Added a unit tester for them.
  • Fleshed out implementation and added unit test.
  • Converted grizzled.string.WordWrapper to be more functional (i.e., got rid of all var usages).
  • Renamed IteratorStream (in grizzled.parsing) to SafeIterator, to avoid confusion with Scala streams. IteratorStream is now a deprecated alias.
  • Deprecated IteratorStream.count(), as its functionality is better handled by callers that care.
  • Converted uses of var in grizzled.string.template classes to val.
  • Added some unit tests for the classes in grizzled.parsing.
  • DOCS: Added package description for

Version 2.3.1:

  • Fixed bug in Zipper (incorrect comparison between StringandChar`).
  • Cleaned up various unused imports.

Version 2.3.0:

  • Added class, which makes creating zip files and jar files easier than using the JDK classes or the Apache Commons Compress classes. In particular, Zipper simplifies the handling and creation of the intermediate directories that contain zip entries. See the docs for details.
  • and have copyTo() methods that previously returned Unit and threw exceptions on error. They now return Try objects.
  • grizzled.file.GrizzledFile (an enrichment of now supports a pathExists method that returns a Try.

Version 2.2.2:

  • Miscellaneous cleanup of unit tests.

Version 2.2.1:

  • Rearranged some code to fix a compilation bug (JDK 1.7, Scala 2.11, on Ubuntu) that appears to be related to SI-2905.
  • Fixed GrizzledString.translateMetachars so that it compiles in the Travis CI environment. The pattern match was too complicated for that environment, which means it might have failed elsewhere, too.

Version 2.2.0:

  • Implemented a simpler, more elegant version of GrizzledString.translateMetachars().
  • grizzled.config.Configuration changes:
    • Restored ability of grizzled.config.Configuration to expand metacharacters in non-raw values.
    • Deprecated the grizzled.config.Configuration.apply() functions, in favor of read() functions that return Try (instead of Either).
    • Changed grizzled.config.ValueConverter to require overriding a Try-based function, rather than an Either-based function.
    • Added implicit value converters for Double and Float.
    • Restored (broken) ability to specify a "not found" function.

Version 2.1.0:

  • Removed unused lib directory and its contained jar files.
  • grizzled.string.WordWrapper is now a case class.
  • Fixed wrapping in grizzled.string.WordWrapper to handle specified "ignore" characters in the prefix, not just in the wrapped text.
  • Deprecated the implicit conversions in and Import to get the same conversions.
  • Refactored some of the test classes.
  • Added a tryGet() method to grizzled.config.Configuration, as a move toward getting rid of Either.

Version 2.0.1:

  • Fixed GrizzledString.translateMetachars. It was not properly parsing Unicode escapes that are embedded in other strings. It would fail on "Here\u0160123", for instance.
  • Added a CanReleaseResource object for, which doesn't extend This allows withResource() to work with objects, without the user having to write a custom CanReleaseResource[Source] object. (Pull request from Adam Lesperance.)

Version 2.0.0 (Incompatible API changes):

  • Added and front-end case class wrappers for the Java equivalents.
  • Renamed to Modified the various download() methods to return Future, and added versions that take
  • Modified the synchronous to take a timeout parameter. Added a version that takes
  • Added unit tests for download functions.
  • Added grizzled.util.Implicits.RichTry enrichment class.
  • Fixes to grizzled.file.Includer:
    • Fixed some problems with URI parsing.
    • Fixed uses of and, to correct problems with detecting the parent location for a relative include.
    • Added comments indicating that doing an include from a can make it difficult to infer the location of a relative include, depending on the underlying resource the Source is reading.
    • Changed Includer companion object constructors to return scala.util.Try, instead of throwing an exception.
    • Added constructors that take
    • Made class constructor private. Use the Includer.apply() functions.
    • Added unit tester.
  • Removed deprecated grizzled.readline package. Use JLine 2, instead.
  • Removed grizzled.cmd. It was a nice idea (based on the concepts in the Python cmd module), but it's not being used, really.
  • Deprecated grizzled.sys.systemProperties. Use scala.sys.SystemProperties or scala.util.Properties, instead.
  • Removed deprecated versions of withCloseable. Use grizzled.util.withResource, instead.
  • Remove the following deprecated objects. The corresponding implicit classes remain, but they're enabled by importing from a corresponding Implicits object (for consistency).
    • grizzled.collection.GrizzledIterable
    • grizzled.collection.GrizzledLinearSeq
    • grizzled.collection.CollectionIterator
    • grizzled.file.GrizzledFile
    • grizzled.string.GrizzledChar
    • grizzled.string.GrizzledString
  • Fixed implementation of grizzled.math.stats.mode to be purely immutable (i.e., not to use a mutable Map under the covers) and to use the Collection API's max method, instead of rolling its own.

Version 1.6.1

  • Added an explicit conversion from to An explicit conversion already exists for the other direction, and implicit conversions already exist in both directions.
  • Built against Scala 2.12-M4, instead of -M1.

Version 1.6.0:

  • Now compiles against Scala 2.12, as well as 2.11 and 2.10.
  • Added activator, for a self-bootstrapping build.
  • Removed unused dependency on scala-async and scala-actors.
  • Added a better message when a CanReleaseResource implicit evidence parameter cannot be found for grizzled.util.withCloseable().
  • Added GrizzledString.escapeNonPrintables and GrizzledChar.isPrintable methods.
  • Added toTry method to the rich Either class, to convert an Either to a Try.

Version 1.5.1:

  • Cleaned up some warnings identified by IntelliJ.
  • Deprecated grizzled.util.withCloseable() and in favor of grizzled.util.withResource().
  • Added some unit tests for the grizzled.file.util.eglob() and grizzled.file.util.glob() functions.
  • Converted remaining unit tests from ScalaTest's FunSuite to FlatSpec.
  • Deprecated enrichment classes that aren't inside objects called Implicits, and added Implicits objects where appropriate, for consistency.

Version 1.5.0:

  • Modified grizzled.string.WordWrapper to allow specification of characters that should be ignored when calculating wrapping.
  • Removed some deprecated methods and classes that have been around for awhile.
  • Added +, ++, - and -- methods to grizzled.config.Configuration, to allow addition to and removal from a Configuration in an immutable way.
  • Updated ScalaTest to 2.2.6 and scala-async to 0.9.5.

Version 1.4.0:

  • Added functions and methods to handle converting IP addresses to and from numeric values.
  • Added a version of IPAddress.apply() that takes a
  • Added, to parse a non-hostname IP address without incurring a DNS lookup penalty.
  • Cleaned up code in
  • Converted various functions to return Try instead of Either.
  • Removed use of deprecated Scala IterableProxy trait.
  • Deprecated the grizzled.readline package. Use JLine2, instead.
  • Build cleanups: Removed SBT "ls" plugin and removed stray repos.
  • Cleaned up Scaladoc warnings.

Version 1.3:

  • grizzled.config.Configuration wasn't properly handling custom regular expressions for parsing section names and comments. Fixed by Stefan Schlott (@Skyr).

Version 1.2:

  • grizzled.config.Configuration is now completely immutable. Specifically, the following changes have been made:
    • Explicit conversion methods (e.g., getInt(), getBoolean()) have been removed, in favor of new asOpt[T]() and asEither[T]() methods. These new methods take an implicit ValueConverter object, allowing callers to specify their own type conversions. Some predefined converters are available in the grizzled.config.Configuration.Implicits package.
    • It is now possible to specify a "not found" handler, when constructing a Configuration object, to handle cases where an option was not found.
    • The Configuration class is now final, because the constructor is now private.
    • All Configuration objects must be instantiated through the companion Configuration object.
    • All methods throwing exceptions have either been deprecated or removed. Implication: Non-safe configuration objects (i.e., those that throw exceptions for variables that cannot be substituted) are not supported. However, asEither() will properly handle that situation.
    • Most exceptions have been removed, except those still thrown by deprecated methods.
  • grizzled.string.util.stringToBoolean() is deprecated, as it throws an exception. Use the new str2Boolean() instead; it returns an Either.
  • Removed exceptions from grizzled.string.StringTemplate. The substitute() method is now deprecated (because it throws exceptions) in favor of the sub() method (which returns an Either).
  • now returns an Either, instead of throwing an exception on error.
  • The functions in grizzled.file.util and the methods in grizzled.file.GrizzledFile now return Either, instead of throwing exceptions.
  • Implicits in the class are now in a special Implicits object.

Version 1.1.6:

  • Removed the grizzled.generator package, as it relies on the unsupported and unmaintained Scala continuations plugin.
  • Changed grizzled.file.util.listRecursively() to use Scala Stream objects, which permit lazy evaluation. It's a better, and simpler, solution than continuation passing.
  • Now cross-compiled for Scala 2.11.
  • Published to Bintray.
  • Updated to SBT 0.13.2

Version 1.1.5:

  • Added grizzled.either, which contains enrichments for the Either class, including map() and flatMap() methods that map when the value is Right (and permits easier use of Either objects in for comprehensions).
  • Increased file copying speed in by adding buffering. (Fix supplied by Jim Fulton
  • grizzled.math.stats.range() of a single value now returns 0, as it should. Addresses Issue #4
  • Upgraded to latest version of ScalaTest.

Version 1.1.4:

  • Added grizzled.string.util.bytesToHexString.
  • Added, a simplified interface to the Java MessageDigest capability.

Version 1.1.3:

  • API documentation changes.
  • Built for Scala 2.10 release.
  • Removed a bunch of deprecated methods.
  • Updated ScalaTest version.
  • Addressed Issue #4: stats.range() broken when passed a single value.

Version 1.1.2:

  • Cross-compiled and published for Scala 2.10.0-RC1.
  • Converted to use ScalaTest 2.0, which changes expect to expectResult.

Version 1.1.1:

  • Re-integrated Doug Tangren's (outstanding) ls SBT plugin.

Version 1.1.0:

  • Built for the Scala 2.10.0 series only (2.10.0-M7, initially). This version, and later versions, are 2.10-only. 2.9.x and earlier will be supported via the 1.0.x release branch. This is due to changes in the Scala library between 2.9 and 2.10.
  • Converted code to use 2.10 reflection API.
  • Added -feature to scalac options, and removed all feature warnings. In many cases, this simply necessitating importing various scala.language packages, such as scala.language.reflectiveCalls and scala.language.implicitConversions.
  • Removed use of val in for comprehensions, as it's now deprecated.
  • Upgraded build to SBT 0.12.
  • Moved GrizzledFile.listRecursively() functionality from GrizzledFile (which is intended to enhance implicitly) to grizzled.file.util package, where it is more easily invoked directly. Replaced GrizzledFile.listRecursively() with a simple wrapper that invokes grizzled.file.util.listRecursively().
  • Converted use of scala.collection.JavaConversions.IterableWrapper (which is deprecated in 2.10) to scala.collection.convert.JIterableWrapper.

Version 1.0.14:

  • Addressed Issue #4: stats.range() broken when passed a single value.

Version 1.0.10:

  • Fixed grizzled.sys.makeNativePath and related functions to treat the Mac platform the same as Posix, instead of throwing an exception.
  • Updated to use SBT 0.11.2.
  • Now publishes artifacts to Artifacts are signed with GPG key, as a result.

Version 1.0.9:

  • Fixed grizzled.readline so that a newline in the prompt doesn't return None (for EOF).
  • Based on pull request #3, by Dan Sully, added the following features to grizzled.config:
    • Section name regular expression can now be specified to Configuration objects, thus allowing alternate section name forms.
    • Comment regular expression can now be specified to Configuration, allowing alternate comment syntaxes.
    • Configuration now supports at getAsList() method, which returns a value split into a string list. Delimiters may be specified. The value returned is of type Option[List[String]].

Version 1.0.8:

  • Fixed an off-by-one error in grizzled.collection.ListIterator
  • Cleaned up Scaladocs considerably.
  • Converted code to confirm with standard Scala coding style.
  • Now builds for Scala 2.9.1, as well as 2.9.0-1, 2.9.0, 2.8.1 and 2.8.0.

Version 1.0.6:

  • Now builds against Scala 2.9.0, as well as Scala 2.8.0 and 2.8.1.
  • Updated to version 1.4.1 of ScalaTest for Scala 2.9.0. (Still uses ScalaTest 1.3, for Scala 2.8).
  • Updated to use SBT 0.7.7.
  • Removed various deprecated methods.
  • Corrected implementation of grizzled.reflect.isOfType for non-primitives.

Version 1.0.5:

  • Miscellaneous internal cleanup of Configuration and grizzled.readline code.
  • Updated to version 1.3 of ScalaTest.

Version 1.0.4:

  • Fixed some error messages in the Configuration class, per an email from brian.ewins /at/

Version 1.0.3:

  • Now builds against Scala 2.8.1 and 2.8.0.
  • Added range() function to the grizzled.math.stats module.
  • Enhanced grizzled.readline module to permit the caller-supplied Completer object to specify the delimiters to use when tokenizing an input line for tab completion.
  • Enhanced grizzled.cmd module to allow the caller to instantiate the CommandInterpreter class with the set of delimiters to use when tokenizing an input line for tab completion.

Version 1.0.2:

  • Added the grizzled.math.stats module, which contains some common statistics functions.
  • Scaladoc documentation is now generated with a proper title.

  • Now published to the Scala Tools Nexus repository, so it's no longer necessary to specify a custom repository to find this artifact.

Version 0.7.4:

  • Added grizzled.reflect module and grizzled.reflect.isOfType() method, which uses scala.reflect.Manifest to simplify erasure-proof type tests. e.g.:

      def test(v: Any) =
          import grizzled.reflect._
          if (isOfType[List[Int]](v))
          else if (isOfType[List[Char]](v))
  • Moved grizzled.parsing.markup to the new, separate MarkWrap library. Among other things, this move keeps the Grizzled Scala library more focused and reduces transitive dependencies.

  • Removed most explicit matches against Some and None, making better use of the Scala API.

  • Updated to released 1.2 version of ScalaTest.

  • Changed dependency on ScalaTest to be a test-only dependency.

Version 0.7.3:

  • Updated to build with Scala only.

Version 0.7.2:

  • Updated to Knockoff version 0.7.2-13, which corrects some Markdown translation bugs.
  • Updated to Scala 2.8.0.RC5. Now builds against RC3 and RC5 only.

Version 0.7.1:

  • Bumped to SBT version 0.7.4.
  • Added relativePath method to GrizzledFile.
  • Added ability to "parse" (i.e., emit) plain text and HTML/XHTML to the grizzled.parsing.markup package.
  • Updated to Knockoff version 0.7.1-12, which corrects some Markdown translation bugs.
  • Fixed grizzled-scala artifact publishing bug (issue #1).
  • Removed support for Scala 2.8.0.RC2.
  • Changed SBT publishing to use an SSH key file, to eliminate the Ivy Swing prompt.

Version 0.7:

  • Added, which extends with mixin methods.
  • Deprecated grizzled.string.implicits and grizzled.file.implicits modules, in favor of more granular imports. See the grizzled.file.GrizzledFile, grizzled.string.GrizzledString and grizzled.string.GrizzledChar companion objects for details.
  • Deprecated the string-to-boolean implicit function, in favor of the more explicit grizzled.string.util.stringToBoolean() method.
  • Changed GrizzledFile.listRecursively to take an optional topdown flag, indicating whether directory traversal should be top-down or bottom-up.
  • Deprecated grizzled.parsing.Markdown in favor of new grizzled.parsing.markup module.
  • Add Textile support to grizzled.parsing.markup, via the Eclipse WikiText library.
  • Changed grizzled.parsing.markup to use Tristan Juricek's Knockoff library for Markdown, rather than invoking the Showdown JavaScript parser via Rhino.
  • Now compiles under Scala 2.8.0.RC3 and RC2. Dropped support for RC1.

Version 0.6:

  • Added findReadline() convenience method to grizzled.readline.Readline. This method attempts to find and load a suitable Readline library.
  • Cleaned up grizzled.file.util.deleteTree method.
  • Added versions of grizzled.file.util.copyFile, grizzled.file.util.copyTree, and grizzled.file.util.deleteTree that take objects.
  • Replaced with the more flexible (useThenClose is still present, but it's deprecated.)
  • Added copyTo() method to grizzled.file.GrizzledFile, which can be implicitly mixed into
  • Ensured that various supposedly tail-recursive methods are marked with @tailrec, to be sure.
  • Maven artifact now includes Scala version (e.g., grizzled-scala_2.8.0.RC2, instead of grizzled-scala).
  • Updated to build against Scala 2.8.0.RC2, as well as Scala 2.8.0.RC1.

Version 0.5.1:

  • Updated to posterous-sbt plugin version 0.1.5.
  • Removed CHANGELOG, because it can now be generated by posterous-sbt.
  • Added grizzled.generator, which can be used to create Python-style generators. (It borrows shamelessly from Rich Dougherty's Stack Overflow post.)
  • Added listRecursively() generator function to grizzled.file.GrizzledFile. Via implicits, GrizzledFile can be used to extend
  • The grizzled.readline.Readline trait now contains a cleanup method, and the grizzled.cmd.CommandInterpreter class now calls it on exit. This change ensures that the terminal isn't left in a weird state.

Version 0.5:

  • Updated to Scala 2.8.0.RC1.
  • Replaced uses of now-deprecated Math functions with corresponding functions from scala.math.
  • Enhanced grizzled.config.Configuration:
    • A forMatchingSections() method allows simple looping over sections that match a regular expression.
    • A matchingSections() methods returns a sequence of sections that match a regular expression.
    • The options() method now returns an empty map if the section doesn't exist, instead of throwing an exception.
    • A new setOption() method overwrites an option value, if it exists already, instead of throwing a DuplicateOptionException, as addOption() does.
    • ConfigurationReader is deprecated, and the logic to read a configuration file has been moved into the Configuration class, to permit easier subclassing.
    • Now supports a "safe load" mode, where exceptions aren't thrown.
    • Added unit tests for the Configuration class.
    • Added ability to retrieve converted integer and boolean option values.
    • The option() methods are now deprecated, in favor of new get() and getOrElse() methods that are modeled after their Map counterparts.
    • Added a new getSection() method that returns an Option[Section].

Version 0.4.2:

  • Updated to SBT version 0.7.3.
  • Added withDownloadedFile() to, to execute a block on a downloaded URL.
  • The module has been replaced by individual modules, for more granular scope control (e.g.,,
  • The package has been split into individual source files.
  • Added new class that wraps a inside a

Version 0.4.1:

  • Fixed inadvertent bug in grizzled.cmd command handling, when commands span multiple lines.

Version 0.4:

  • Added grizzled.collection.GrizzledLinearSeq and related implicits, as a place to put additional methods for sequences.
  • Added grizzled.collection.GrizzledLinearSeq.columnarize(), which takes a sequence (e.g., a list), converts its contents to strings, and returns a single string with the sequence's contents arranged in columns.
  • Rearranged the locations of various implicit functions, so callers can have finer-grained control over which ones are in scope.
  • grizzled.editline.EditLine now shows its completions in columnar format.
  • Added BlockCommandHandler to grizzled.cmd, to handle commands consisting of blocks of lines between a start and end line.
  • Added HiddenCommandHandler to grizzled.cmd, allowing special commands that are not displayed in the help.
  • Changed EOF handling in grizzled.cmd slightly.
  • Added createTemporaryDirectory() and withTemporaryDirectory() to grizzled.file.util module.
  • Added isEmpty to grizzled.file.GrizzledFile (which can be implicitly converted to and from
  • Fixed problem with prefix handling in grizzled.string.WordWrapper.
  • Now uses SBT 0.7.2 to build from source.

Version 0.3.1:

grizzled.cmd changes:

  • "history" command now uses the syntax history [-n] [regex] where n is the maximum number of entries to show, and regex is a regular expression to filter history entries.

  • Some commands starting with "." were being incorrectly limited to a single character (e.g., ".r", but not ".read").

  • General clean-up and bug fixing in the "redo command" handler.

  • CommandHandler classes can now exempt themselves from the history.

  • The RedoCommandHandler (which handles the "r" and "!" commands) now exempts itself from the history.

Version 0.3:

  • Converted to Scala 2.8.0
  • Now must be compiled with SBT version 0.7.0 or better.
  • Fixed tail call optimization problem in Thanks to Claudio Bley (cbley /at/
  • Added grizzled.parsing.MarkdownParser, for parsing Markdown documents. (Currently uses the Showdown Javascript library, via Mozilla Rhino.)
  • grizzled.cmd.HelpHandler now supports a ".help" alias.
  • Added grizzled.util.withCloseable control structure.
  • The grizzled.readline API now uses the Java EditLine wrapper for the Unix EditLine library, instead of the one in Java-Readline. implementation, instead of the one in Java-Readline. Completion handling is more reliable with the Java Editline implementation.
  • grizzled.cmd now tries to load EditLine first.

Version 0.2:

  • In grizzled.cmd, the default handler for the "help" command now does tab completion on the existing commands.
  • Changed the way grizzled.readline exposes completion context. Instead of exposing a cursor, it exposes a tokenized list, with a special Cursor token. This approach fits better with Scala's pattern matching.
  • grizzled.collection.MultiIterator is now covariant, not invariant.
  • Miscellaneous internal changes where yield is used.
  • Changed license to New BSD License.

Version 0.1:

  • Initial release.
  • Fixed an off-by-one error in grizzled.collection.ListIterator
  • Cleaned up Scaladocs considerably.
  • Converted code to confirm with standard Scala coding style.
  • Now builds for Scala 2.9.1, as well as 2.9.0-1, 2.9.0, 2.8.1 and 2.8.0.
