Dick Hollenbeck 84ed5f501d ++new:
* Added the basic structure to the Sweet parser in sch_part.cpp.
  * Got inheritence working off of the 'extends' keyword and PART::inherit()
  * Tossed the units support out of sweet.keywords, since we agreed to go dimensionless.
++richio:
  * Added the problemInputLine support to PARSE_ERROR, so UI can show the
    offending line of bytes.  Yes bytes, not even guaranteed to be characters.

dickelbeck aba543cb54 clipboard and DSNLEXER testing via target dsntest 2010-03-08 16:17:58 +00:00
dickelbeck f1f11cf66d revive target 'dsntest' from common, start exploring pasting text from clipboard, primitively. 2010-03-08 06:18:40 +00:00
dickelbeck 2decdbdd14 ++common
* DSNLEXER now owns an abstract LINE_READER by pointer so that polymorphism
    can be used in alternative LINE_READERS.
  * Write FILE_LINE_READER and STRING_LINE_READER.  The latter can be used
    to parse text coming from the clipboard or other string source.

dickelbeck a800351eab Switch the LINE_READER being used by DSN_LEXER as owned, and accessible via pointer.
This paves the way for other kinds of LINE_READERs, such as one which reads from a
multiline string which comes from the clipboard. 

Will still need to:
1) add new additional DSN_LEXER constructor,
2) virtualize the LINE_READER's ReadLine() function
3) create derived class from LINE_READER.

dickelbeck 6700c604aa DSNLEXER now supports:
1)  nested quotes.  This is in anticipation of broader usage of the
        file type/syntax.  A string like this in the file:
            "my ""favorate"" string"
        can be returned as
            my "favorite" string
    2)  CommentsAsTokens is implemented, so you can ask the lexer to return
        comments as tokens, so they can be preserved.  The default is to ignore
        them.  A comment is defined as any line that has # as its first
        non-blank character.  (This means comments cannot follow anything else
        on a line.)

dickelbeck ceb6ad1a72 * Factored out the DSNLEXER class so it can be re-used more generally. The
constructor takes a keyword table, so it can be used for arbitrary DSN
    syntax files of your own chosing.  Simply create an enum {} with all your
    unique tokens in it.  Then create a KEYWORD table.  See SPECCTRA_DB::keywords[].
    The reason you want an enum is to give the C++ debugger better type information
    so it can show symbolic integer symbols.
  * Factored out common richio.cpp and richio.h
    which is what DSNLEXER uses.
  * Fixed some minor issues with reading circuit descriptor from a *.dsn file.
