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 + +*/ + +%option never-interactive +%option yylineno +%option noyywrap +%option reentrant stack + + +%{ + +#include "token.h" +#include "lexer.h" +#include + +extern void *bbparseAlloc(void *(*mallocProc)(size_t)); +extern void bbparseFree(void *p, void (*freeProc)(void*)); +extern void *bbparseAlloc(void *(*mallocProc)(size_t)); +extern void *bbparse(void*, int, token_t, lex_t*); +extern void bbparseTrace(FILE *TraceFILE, char *zTracePrompt); + +//static const char* rgbInput; +//static size_t cbInput; + + +int lineError; +int errorParse; + +enum { + errorNone = 0, + errorUnexpectedInput, + errorUnsupportedFeature, +}; + +#define YY_EXTRA_TYPE lex_t* + + /* Read from buffer */ +#define YY_INPUT(buf,result,max_size) \ + { yyextra->input(buf, &result, max_size); } + +//#define YY_DECL static size_t yylex () + +#define ERROR(e) \ + do { lineError = yylineno; errorParse = e; yyterminate (); } while (0) + +static const char* fixup_escapes (const char* sz); + +%} + + +C_SP [ \t] +COMMENT #.*\n +OP_ASSIGN "=" +OP_IMMEDIATE ":=" +OP_PREPEND "=+" +OP_APPEND "+=" +OP_COND "?=" +B_OPEN "{" +B_CLOSE "}" + +K_ADDTASK "addtask" +K_ADDHANDLER "addhandler" +K_AFTER "after" +K_BEFORE "before" +K_DEF "def" +K_INCLUDE "include" +K_INHERIT "inherit" +K_PYTHON "python" +K_FAKEROOT "fakeroot" +K_EXPORT "export" +K_EXPORT_FUNC "EXPORT_FUNCTIONS" + +STRING \"([^\n\r]|"\\\n")*\" +SSTRING \'([^\n\r]|"\\\n")*\' +VALUE ([^'" \t\n])|([^'" \t\n]([^\n]|(\\\n))*[^'" \t\n]) + +C_SS [a-zA-Z_] +C_SB [a-zA-Z0-9_+-.] +REF $\{{C_SS}{C_SB}*\} +SYMBOL {C_SS}{C_SB}* +VARIABLE $?{C_SS}({C_SB}*|{REF})*(\[[a-zA-Z0-9_]*\])?
