[set_preprocessor init preprocessor] registers [init] as the function
|
|
to call to initialize the preprocessor when the lexer is initialized,
|
|
and [preprocessor] a function that is called when a new token is needed
|
|
by the parser, as [preprocessor lexer lexbuf] where [lexer] is the
|
|
lexing function.
|
|
|
|
When a preprocessor is configured by calling [set_preprocessor], the lexer
|
|
changes its behavior:
|
|
- It accepts backslash-newline as a token-separating blank.
|
|
- It emits an EOL token for every newline except those preceeded by backslash
|
|
and those in strings or comments.
