Hi All, ===== TASK ======
In SQL we must be able write SELECT 'aaa' 'bbbb' And this should be same as SELECT 'aaabbbb' I.e. Parser must concatenate literals self. This was quite easy do in ANTLR 2, and I already have kill 5-6 hours in ANTLR 3. :-(((((( I have try many tricks for ANTLR3 itself trying to use its tokens and ANTLR_STRING class but no luck. Finally I have give up and have try to use simple code as in v2 using STD::string as place to accumulate literal. ================================= character_string_literal @init{ STD::string st; } : ( STRING_LITERAL { st.append( (const char*) $STRING_LITERAL.text->chars, $STRING_LITERAL.text->len ); } )+ -> ^( CONST_STR[ st.c_str() ] ) ; ================================= But this not works, because new Token object stores just pointer newToken->textState = ANTLR3_TEXT_CHARP; newToken->tokText.chars = (pANTLR3_UCHAR)text; And as only STD::string dies we get problem. Jim, how this simple task can be solved in the C TARGET ? Also I see that for Java code they can contruct dynamic text And produce token using that text. For example on this page http://www.antlr.org/wiki/display/ANTLR3/Tree+construction -> ^('+' $p INT[String.valueOf($a.int+$b.int)]) But C target tryies to work only which char* I guess that ANTLR_STRING setText() can help me, But I cannot see how I can call that from my -> ^( CONST_STR[ st.c_str() ] ) ???
