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

DESCRIPTION
|
||||
-----------
|
||||
|
||||
lemon parser specification file for a BitBake input file parser.
|
||||
|
||||
Most of the interesting shenanigans are done in the lexer. The
|
||||
BitBake grammar is not regular. In order to emit tokens that
|
||||
the parser can properly interpret in LALR fashion, the lexer
|
||||
manages the interpretation state. This is why there are ISYMBOLs,
|
||||
SYMBOLS, and TSYMBOLS.
|
||||
|
||||
This parser was developed by reading the limited available
|
||||
documentation for BitBake and by analyzing the available BB files.
|
||||
There is no assertion of correctness to be made about this parser.
