1bef45ff47 Lexer: Added ::decomposeSubstitution and more flexible ::dequote 
- ::dequote can now be given a string of valid quote characters, which defaults
  to '".
- ::decomposeSubstitution properly parses the /from/to/g construct allowing for
  escaped characters (\/).
- The 'g' at the end of a substitution is now considered to be a string of flag
  characters, which may contain 'g'. No other flag values are currently
  supported.

38359b779a Lexer 
- Exposed more primitives as static methods.
 2014-11-04 22:51:25 -05:00

68fb1136cc Lexer 
- Added notes about additional lexeme types that are needed, long term.

9778100d29 Lexer 
- When parsing two-character operators ('or') from a string ('ordinary'), the
  lack of boundary between the 'r' and the 'd' now prevents the operator 'or'
  from being recognized.
 2014-07-03 16:26:17 -04:00

65f979cb4f Lexer 
- Refactored (step 1) the ISO and Legacy date/duration parsing for lexer state
  machine breakout.

008ba6ecab Lexer 
- Implmented boundary detection hints.

7d4e166277 Lexer 
- Implemented an overload of ::token_split that preserveѕ types.
 2014-06-14 13:46:10 -04:00
Paul Beckingham
2554b29041 Lexer 
- Needed a shift counter, rather than a read counter, as ::token was
  lexing '-10d' into '-' and '-10d', which when evaluated is '--10d',
  which yields 10d.
 2014-06-10 15:42:21 -04:00
Paul Beckingham
7598997e70 Lexer 
- Implemented ::token_split, which performs a full lex, and doesn't require
  white space like ::word_split does.
- Added unit tests.
 2014-05-31 13:51:10 -04:00
Paul Beckingham
0af9bbdc03 Lexer 
- Renamed ::split to ::word_split, for clarity and because of the need for a
  full token split, coming next.

592a3bb60f Lexer 
- Lexer now makes a speculative legacy dateformat parse whenever it encounters
  a decimal digit.  This assumes that rc.dateformat begins with a numeric date
  element, which is a restriction, but not a big one.
 2014-05-29 18:09:11 -04:00
Paul Beckingham
611812007a Lexer

- Implemented Lexer::split, which uses Lexer::word.
- Added unit tests.
