I've having a hard time getting my parser to work correctly. I'm trying to create a script parser to create tests, actions, and groups defined in a file. I have the grammer working except for one small issue. I can't get rid of the closing quote on my sentence. It skips the first one just fine. I'm using spirit 1.6.2 The script is below named script.txt: ---------------------- Groups {G100, "This is group G100", G200, "This is group G200" } Actions {A100, "This is an action" } Tests {T100, "This is a test", 0, 5, "VDC" } TestFlow {a } ---------------------------------- I want to have the option of using double quotes (") around strings for the discriptions in Groups, Actions, and Tests section to make it easier to read. I use comma as a delimiter. Here is my spirit code below: ---------------------------------- #include <iostream> #include <fstream> #include <vector> #if defined(_DEBUG) //#define BOOST_SPIRIT_DEBUG #endif // defined(_DEBUG) #include "boost/spirit.hpp" #include #include #include //////////////////////////////////////////////////////////////////////////// /// // used namespaces using namespace boost::spirit; using namespace std; namespace { void my_action(char const* first, char const* last) { std::string str(first, last); std::cout << str << std::endl; } void my_number(float val) { std::cout << val << std::endl; } } struct script_grammar : public grammar { template <typename ScannerT> struct definition { definition(script_grammar const& self) { Group_Composite = Group >> BeginBrace >> +Group_Action_Parms >> EndBrace; Action_Composite = Action >> BeginBrace >> +Group_Action_Parms >> EndBrace; Test_Composite = Test >> BeginBrace >> +Test_Parms >> EndBrace; TestFlow_Composite = TestFlow >> BeginBrace >> +TestFlow_Parms >> EndBrace; Group = as_lower_d[str_p("groups")]; Group_Action_Parms = Token[&my_action] >> Comma >> Token[&my_action] >> !Comma; Action = as_lower_d[str_p("actions")]; Test = as_lower_d[str_p("tests")]; Test_Parms = Token[&my_action] >> Comma >> Token[&my_action] >> Comma >> real_p[&my_number] >> Comma >> real_p[&my_number] >> Comma >> Token[&my_action] >> !Comma; TestFlow = as_lower_d[str_p("testflow")]; TestFlow_Parms = Token; BeginBrace = ch_p('{'); EndBrace = ch_p('}'); Comma = ch_p(','); Token = +Token_Sub; Token_Sub = alnum_p; //(alnum_p - ch_p(34)); // ^ ch_p('\"')); first = *( Group_Composite | Action_Composite | Test_Composite ) >> TestFlow_Composite; BOOST_SPIRIT_DEBUG_RULE(Group_Composite); BOOST_SPIRIT_DEBUG_RULE(Action_Composite); BOOST_SPIRIT_DEBUG_RULE(Test_Composite); BOOST_SPIRIT_DEBUG_RULE(TestFlow_Composite); BOOST_SPIRIT_DEBUG_RULE(Group); BOOST_SPIRIT_DEBUG_RULE(Group_Action_Parms); BOOST_SPIRIT_DEBUG_RULE(Action); BOOST_SPIRIT_DEBUG_RULE(Test); BOOST_SPIRIT_DEBUG_RULE(Test_Parms); BOOST_SPIRIT_DEBUG_RULE(TestFlow); BOOST_SPIRIT_DEBUG_RULE(TestFlow_Parms); BOOST_SPIRIT_DEBUG_RULE(BeginBrace); BOOST_SPIRIT_DEBUG_RULE(EndBrace); BOOST_SPIRIT_DEBUG_RULE(Comma); BOOST_SPIRIT_DEBUG_RULE(Token); BOOST_SPIRIT_DEBUG_RULE(first); BOOST_SPIRIT_DEBUG_RULE(Token_Sub); } rule<ScannerT> Group_Composite, Action_Composite, Test_Composite, TestFlow_Composite, Group, Group_Action_Parms, Action, Test, Test_Parms, TestFlow, TestFlow_Parms, BeginBrace, EndBrace, Comma, Token, Token_Sub; rule<ScannerT> first; rule<ScannerT> const& start() const { return first; } }; }; struct skip_grammar : public grammar { template <typename ScannerT> struct definition { definition(skip_grammar const& /*self*/) { skip = space_p | ch_p('\"') ; BOOST_SPIRIT_DEBUG_RULE(skip); } rule<ScannerT> skip; rule<ScannerT> const& start() const { return skip; } }; }; template<typename GrammarT> void parse(GrammarT const& g, char const* filename) { ifstream in(filename); if (!in) { cerr << "Could not open input file: " << filename << endl; return; } in.unsetf(ios::skipws); // Turn off white space skipping on the stream vector<char> vec; std::copy( istream_iterator<char>(in), istream_iterator<char>(), std::back_inserter(vec)); vector<char>::const_iterator start = vec.begin(); vector<char>::const_iterator end = vec.end(); skip_grammar skip; parse_info result = parse(start, end, g, skip); if (result.full) cerr << filename << " Parses OK" << endl; else { cerr << filename << " Fails Parsing" << endl; for (int i = 0; i < 50; i++) { if (result.stop == end) break; cerr << *result.stop++; } cerr << endl; } } // main entrypoint int main(int argc, char* argv[]) { // Start grammar definition cerr << "Start of Parsing ..." << endl; // main driver code script_grammar g; if (2 == argc) parse(g, argv[1]); else cerr << "No filename given" << endl; return 0; } The output looks like this: Start of Parsing ...
