Version 2.1.4, released 2010-05-26

Enhancements

• Regex split method
• Var split method

Version 2.1.3, released 2010-03-18

Enhancements

• json - Parse and generate JSON

Version 2.1.2, released 2010-03-08

Enhancements

• memoize - memoize method/function results

Version 2.1.1, released 2010-02-22

Important Notes

• The command-line syntax for the htmlcover utility has changed. The previous syntax will no longer work.

Enhancements

• New classes
  • Random - generate random numbers
  • CommandLine - parse command line
• Regex
  • Added escape method
  • Improved compilation performance
  • Optimized leading, unconditional \G
• ls
  • Added reduce and reduceRight methods
• htmlcover
  • Ability to sample more than one executable in a single report
  • -t option to specify report title

Version 2.1.0, released 2010-02-17

Enhancements

• Regex
  • \G to anchor to the end of the last match, and ContinueFrom member
  • Continue option ('c')
  • Allow lowercase \ca..\cz for control characters
  • GNU anchors and word boundaries: \`, \', \<, \>
  • Allow duplicate group names, capturing to the same group
  • Alternate (.NET) syntax for named group capture
  • Alternate (.NET) syntax for named group back-reference
  • POSIX character classes, including [: :] and \p{ } (Java) syntax
  • $ tokens for replace
  • \x00 thru \xFF for replace

Corrections

• Change File to allocate channels above 255 when not in Toolkit mode, to avoid later collision with U_START (which can close channels 1 thru 255).

Version 2.0.4, released 2010-02-12

Enhancements

• Regex
  • DotMatchesNewline option ('s')
  • ExplicitCapture option ('n')
  • Dynamic options: (?imnxs) and (?-i-m-n-x-s).
  • Look-ahead (?= ), (?! ); and look-behind (?<= ), (?<! )
  • Conditionals: (?(group) ), (?(?= ) ), (?(?! ) ), (?(?<= ) ), and (?(?<! ) )
  • \y and \Y as equivalents for \b and \B (a la TCL)
  • \m for beginning of word, \M for end of word
  • Improved performance of the compilation phase
• ls
  • Improved performance of reverse

Corrections

• Regex
  • A named group nested in an unnamed group lost the unnamed group's back-reference
  • Dot should not match newline (%char(10)) unless new DotMatchesNewline option is enabled
• CodeCoverage
  • "No object for handle" error in Markup phase

Version 2.0.3, released 2010-02-02

Important notes

• For performance, I changed the CodeCoverage.Map and the CodeCoverage.SourceFile.lines from associative lists to Hashes. If you access either of these directly, you may need to modify your code accordingly.

Enhancements

• Regex
  • {n} and {n,m} to specify minimum/maximum repetitions.
  • ? following *, +, ?, or {} to indicate non-greediness.
  • \A and \Z,\z for begin and end anchors, respectively.
  • \b for word boundary, \B for not a word boundary.
  • \a for bell, \e for escape.
  • \Q..\E to quote text literally.
  • (?P<group>) for named group capture.
  • (?P=group) for named group back-reference within the pattern.
  • \g<group> for named group substitution in replace
  • Character class subtraction: [a-z-[aeiou]] matches consonants, for instance.
  • Improved performance on matching an unconditional \A or ^.
  • Optimized matching when we can rule out further better matches.
• CodeCoverage
  • Improved performance by replacing associative lists with hashes.
  • Added ProgressHandler class to provide progress reporting.
  • The htmlcover utility now reports more detailed progress to stdout.

Corrections

• Regex
  • replace with a \ at the end should treat \ as a character.
  • /a*/ should always match position 1, with length of zero or more.
  • /()*/ should always match position 1, with a length of zero.
  • Avoid infinite recursion on repeating, potentially zero-length matches like /(a?)*/ or /(a*b*)*/
• Assertions
  • On .NET, capture the inner exception when an exception is thrown from within xsubr.

Version 2.0.2, release 2010-01-20

Enhancements

• CodeCoverage
  • Sampling performance improved by caching current source file between statements.
• Regex
  • \1 thru \9 back-reference within the pattern.
  • (?:) for grouped sub-expression without back-reference.
  • (?#) for comment.
• ls
  • Added deepcopy method to copy all nested lists.
  • Improved performance of quicksort and mergesort, and changed sort to use the best one for each segment, based on size.
• Improved coverage in unit tests

Corrections

• Change GotToolkit to use E_INFO(D_ENV_LEVEL) to test for Toolkit activation (per tr#30959)
• Var.ToHtml() progressively off by one when expanding tabs
• Version.Letter was null when parsing an invalid version, changed to empty string

Version 2.0.1, released 2009-12-31

Enhancements

• Regex
  • Support for extended syntax option (x)
  • Improved performance by removing dead-end optimization and other unnecessary code
• CodeCoverage
  • Better recognition of USING labels
  • Better handling of continuation lines
  • Exclude CATCH statement
  • Recognize jump into CATCH paragraph
  • Map filenames without regard to case (except on Unix)
• Added D_UNIX definition for all *n?x platforms
• Improved coverage in unit tests

Corrections

• Comparable mixin: decimal COMPARE_MEMBER on .NET produced unreliable results
• File.Close when channel already closed gave RETURN without CALL on .NET
• If more than two assignments occurred in a let, the second thru next-to-last would not be released.
• ls.subseq limiting upper index off by 1, resulting in index out of bounds.
• Decrementing a decimal Var failed on .NET
• CompareString.TestNatural used the wrong index when testing for space in the second operand.
• CompareString.TestNatural same number at the end of operands caused an indexing error.
• Regex: match against /^/ yielded length of 1, corrected to 0.
• Tests for mixins included files with initial uppercase character - changed to all lower-case

Version 2.0.0, released 2009-12-26

Important Notes

• Synthesis now requires at least version 9.3.1 of Synergy/DE

Enhancements

• New classes:
  • Version
  • Transport
  • Socket
  • Telnet
  • CodeCoverage
• New utilities for code coverage analysis: cover and htmlcover.
• ls constructor for specifying initial capacity.
• Methods increment, decrement, and ToHtml for the Var class.
• Display method for the File and Console classes.
• Close method for the File class.
• Dispose method for the Hash class.
• Various type declarations for the first argument to fif, to avoid casting to boolean.
• Var.AsAlpha() for decimal Vars no longer includes trailing zeros or decimal point unless significant.

Corrections

• Regexen with complex nested subexpressions.
• Handle regular expressions with ^ or $ within parentheses.
• Insure alphanumeric/string comparisons use string comparison operators (.eqs., etc.) to test for equal length as well as contents.

Limited compatibility with Synergy.NET beta, which required numerous changes, including:

• Rewrote the internals of build_message() for assertions.
• Handle distinctions between types i, int, and boolean.
• Handle distinctions between types d and decimal.
• Create D_EQUALS_PARAM macro for declaring parameter to object.Equals
• Create D_INARG macro for declaring input parameters as byval for .NET only
• Don't override object.MemberwiseClone in .NET
• Declare ls.remove as 'new' for .NET
• Don't provide ls.contains for .NET (already provided by ArrayList)
• Abstract classes cannot be nested classes
• Create makefile dependencies 'net', 'cleannet', and 'runnet'
