- DESCRIPTION
- -----------
-
- flex lexer specification for a BitBake input file parser.
-
- Unfortunately, flex doesn't welcome comments within the rule sets.
- I say unfortunately because this lexer is unreasonably complex and
- comments would make the code much easier to comprehend.
-
- The BitBake grammar is not regular. In order to interpret all
- of the available input files, the lexer maintains much state as it
- parses. There are places where this lexer will emit tokens that
- are invalid. The parser will tend to catch these.
-
- The lexer requires C++ at the moment. The only reason for this has
- to do with a very small amount of managed state. Producing a C
- lexer should be a reasonably easy task as long as the %reentrant
- option is used.
-
-
- NOTES
- -----
-
- o RVALUES. There are three kinds of RVALUES. There are unquoted
- values, double quote enclosed strings, and single quote
- strings. Quoted strings may contain unescaped quotes (of either
- type), *and* any type may span more than one line by using a
- continuation '\' at the end of the line. This requires us to
- recognize all types of values with a single expression.
- Moreover, the only reason to quote a value is to include
- trailing or leading whitespace. Whitespace within a value is
- preserved, ugh.
-
- o CLASSES. C_ patterns define classes. Classes ought not include
- a repitition operator, instead letting the reference to the class
- define the repitition count.
-
- C_SS - symbol start
- C_SB - symbol body
- C_SP - whitespace
