Revision history for CORBA-IDLtree

2.06  2025/04/20
      * In the SUBORDINATES of ENUM, when $enable_comments is set
        change the layout for a comment to conform to the REMARK
        node layout.
      * Change sub info to only print if $verbose is set.
      * Fix handling of annotations applied on members of
        constructed types.
      * On encountering unknown annotation, downgrade severity
        from error to warning.

2.05  2021/06/13
      * Increase minimum required perl version to 5.8 due to
        addition of "use utf8".
      * Add handling of Windows CP-1252 character encoding in
        input file:
        - Add `use utf8`.
        - Require module Encode::Guess.
        - In sub get_items:
          - On encountering a non printable character call
            Encode::Guess->guess.
          - If the call returns a ref then a decoder was found
            and no special action is required.
          - If the call returns "No appropriate encodings found"
            then assign $l from Encode::decode("cp-1252", $l).
          - If the call returns none of the above then print a
            warning "Unsupported character encoding" and replace
            the non printable characters in $l by space.
        - In sub Parse_File_i case $file case $emucpp call to
          `open $in`, the encoding directive for UTF-8 is no
          longer needed due to use of Encode::Guess (see above).
      * In sub skip_input fix handling of preprocessor directives
        where the "#" is not placed in column 1 but is preceded by
        whitespace.
      * Fix sub scoped_name in case of chained module reopenings.

2.04    2020/06/20
        * In sub Parse_File_i case $file case $emucpp open $in
          with encoding(UTF-8) to ensure that IDL files are parsed
          as utf8.
        * New sub discard_bom discards a possible Unicode or UTF-8
          BOM (Byte Order Mark) at the start of the given line.
          In sub get_items add optional argument $firstline.
          If $firstline is given and true then discard_bom will be
          called on the first line read from file.
          In sub Parse_File_i outer while-loop add local
          $firstline for call to sub get_items.
        * New sub has_default_branch checks whether the given union
          subordinates contain a DEFAULT branch.  This fixes a bug
          related to checking that a union has an enum type as its
          switch and does not have a default branch.
          A false warning was generated in case the default branch
          was preceded by a comment.
        * Improvements to preprocessor emulation:
          - Support "#if defined XYZ" without parentheses around
            the symbol.  Fix evaluation of the symbol.
          - Do not attempt evaluating preprocessor directives when
            inside multi line comments.
          - Fix handling of #endif in nested #if/#ifdef/#ifndef.
        * In @annoDefs add java_mapping annotations defined by the
          IDL4 to Java mapping proposal.

2.03    2019/04/27
        * Fixed a bug related to Dump_Symbols whereby when using
          a string array ref as the optional argument, repeated
          calls to the sub would accumulate the text.
        * In sub parse_members, optional argument $comment fixes
          processing of trailing comment at members of struct,
          exception, and valuetype.

2.02    2018/08/15
        * Fixed a few typos in documentation.
        * Added support for IDL4 struct inheritance defined by the
          Building Block Extended Data-Types:
          In case of STRUCT, the first SUBORDINATES element of may
          be a reference to a further STRUCT node instead of the
          reference to quintuplet. In this case, the first element
          indicates the IDL4 parent struct type of the current
          struct.  The function isnode() can be used for detecting
          this case. The support for IDL4 struct inheritance is
          implemented in sub Parse_File_i case $kw eq 'struct'.
