Need help with variation of "Employee" sample

Michael Blinchevsky — 2008-12-02T16:32:07

My experience with parsing is miniscule. I created a small parser in spirit 1.8 and was very happy with it. Now I am trying to expand it and move to spirit2. My goal is to create parser in spirit2 that will parse sql-like commands. These commands resemble sql select statement, so I thought I will create a structure (commandselect in the code below) that will have command title ("select") and various structures for parts of the select command. My first command option is a "frequency" option which is an integer followed by the resolution type, for example 10 F2 , or 1 F1. Frequency types are predefined. For testing I am trying to parse a string SELECT 15 F2 Below is my attempt to do the parser using Employee sample from the documentation. It does not compile. Headers for it are taken from Employee sample. Your help will be greatly appreciated. struct frequency { // frequency portion of the command. Example: 30 F1 or 16 F2 or similar int value; int resolution;// resolution is supplied as a string. // After parsing this value should be mapped value from one of allowed frequencies() entry }; BOOST_FUSION_ADAPT_STRUCT ( frequency, (int, value) (int, resolution) ) struct commandselect {// command itself. Example: SELECT 30 F1 or SELECT 16 F2 std::string title; frequencydatafrequency; }; BOOST_FUSION_ADAPT_STRUCT( commandselect, (std::string, title) (frequency, datafrequency) ) // this structure holds allowed string values for "frequency" input struct frequencies_ : symbols { frequencies_() { add ("F1" , 10) ("F2" , 20); } } frequencies; template struct command_parser : grammar { command_parser() : command_parser::base_type(start) { ruleFrequency %= eps [_val = 0] >> int_ >> frequencies; start %= eps [_val = 0] >> lit("SELECT") >> ruleFrequency; } rule ruleFrequency; rule start; }; int _tmain(int argc, _TCHAR* argv[]) { typedef std::string::const_iterator iterator_type; typedef command_parser select_parser; select_parser parser; return 0; } ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Change scanner

Dainis — 2008-12-02T14:23:00

Hi! I'm new to Spirit, any ideas to better way how to change many early writed rules with empty template ( rule<>) to rules with case insensitive ( rule ::type>) . I know i can simply search and replace in c++ source in all rule definitions, but why not works this : rule::type> otherrule = str_p("ddeee"); rule ::type> ruletest = 'd' >> otherrule; parse("dddEEE",ruletest ) -- is ok, but rule<> otherrule = str_p("ddeee"); rule ::type> ruletest = 'd' >> otherrule; parse("dddEEE",ruletest ) -- is bad? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

bug? char_('<') [val_=_1] fails compile

Larry Evans — 2008-12-02T05:56:21

The attached only has one production whose rhs is just a char_; yet, it only compiles when both then branches of the #if's are active. I had assumed that since the attribute of xml was char, a char_ on the rhs of the xml production would work; however, it doesn't. Should it? I also assumed that using char_(char*) on the rhs would allow any char in the arg list to be successfully parsed. Is that assumption correct? Any help would be appreciated. -regards Larry ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/_______________________________________________ Spirit-general mailing list Spirit-general< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/spirit-general

rule actions

ian eyberg — 2008-12-01T17:42:22

Hi, I've been going through the documentation on the website on rule actions, and still am not understanding them fully. I have an rule that is something like this: myrule = str_p("blahtxt")[assign(self.action.name)]; this correctly throws 'blahtxt' into my action.name variable I'm looking to do something like this: myrule = str_p("blahtxt")[self.action.name = "myblah"]; where self.action.name would now hold "myblah" Surely, I'm just overlooking something obvious here.

[spirit2] compile time

Joel de Guzman — 2008-12-01T15:50:38

Hi, I'm sure you all know that I am tweaking spirit2 inside out to squeeze more compile time performance. Here are some numbers so far. The most complex example in the spirit2 examples folder is the mini-C compiler (compiles a very simple C like language to a virtual machine). It is as close to a real world application while still maintaining simplicity for the purpose of instruction. Some numbers: spirit2 (in boost trunk): 2 minutes, 37.9 seconds spirit2x (experimental in spirit svn): 1 minute, 46.2 seconds What's interesting about the mini-C compiler is that I tried as much as possible to apply all tricks (***) to make it build faster, like e.g. composing separate grammars, separating the grammar definitions (the constructors) in separate cpp files, explicit instantiation of the templates, etc. So, while the original 2 minutes, 38 seconds is not bad at all to begin with (considering the /relative/ complexity of the grammar(s)), now we have a definite speedup. I'm quite happy. Let's hope we gain some more. Hardware Specs: Core-2 Duo, 2.4Ghz, 4GB memory Software Specs: MSVC 9.0 on Windows XP (***) I'll try to document the tricks. Call it "spirit: best practice", if you will. The Mini_C compiler has 25 rules, complete with semantic actions. The rules have varying complexity from the simplest one-liner to a 28 line rule. Regards,

[karma] streaming empty containers

Matthias Vallentin — 2008-12-01T02:02:07

Hi there, how do I reliably stream containers regardless of their size? The following example only works with non-empty containers: std::vector v; std::cout << boost::spirit::karma::format( '{' << (stream % ", ") << '}', v ) << std::endl; If the container is empty the output is {% and does not include a closing bracket. In fact, the entire stream is cut off at the point of the first '{'. Of course, I could manually check if the container is empty but it would be sweet if karma can handle empty containers as well (output: "{}"). Could it be that I am misusing karma here? Matthias

Simple suggestion for BOOST_FUSION_ADAPT_STRUCT

Raindog — 2008-12-01T00:10:11

Perhaps for structures whose main purpose is to be used w/ fusion, a macro can be used that will both define the structure and adapt it so that: struct foo { int var1; int var2; std::string name; std::string name2; }; BOOST_FUSION_ADAPT_STRUCT( foo, (int, var1) (int, var2) (std::string, name) (std::string, name2) ) Can be shorted to something like: BOOST_FUSION_DEFINE_AND_ADAPT_STRUCT( foo, (int, var1) (int, var2) (std::string, name) (std::string, name2) ) ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

[karma] streaming a std::map

Matthias Vallentin — 2008-11-30T18:54:14

Hi, could someone give me a short example how to stream std::map? I understand how to stream a std::vector with karma: out << karma::format( '{' << (stream % ", ") << '}', container ); If container is a vector, T needs operator<<. Would it make sense to provide an operator<< for std::map::value_type in order make the above code snippet work? Matthias

problem with simple grammar action.

Raindog — 2008-11-30T09:57:22

Hello, I've just created my first grammar and it worked on line at a time usage, but I wanted it to be able to operate on whole files at once and give me back a vector of what I was parsing. The following is working for a file that contains only parsable lines of text: struct foo_parser: boost::spirit::qi::grammar(), space_type> { foo_parser() : foo_parser::base_type(signatures) { signatures %= *(signature_r) ; signature_r %= '{' >> hex_number >> ',' >> hex_number >> ',' >> hex_number >> ',' >> hex_number >> ',' >> quoted_string >> '}' >> ',' >> comment ; quoted_string %= lexeme [ '"' >> +(char_ - '"') >> '"' ] ; comment %= lexeme [ lit("//") >> +(char_ - eol) >> eol ] ; hex_number %= lit("0x") >> hex ; } boost::spirit::qi::rule quoted_string, comment; boost::spirit::qi::rule signature_r; boost::spirit::qi::rule hex_number; boost::spirit::qi::rule(), space_type> signatures; }; Now what I was trying to do was modify the signatures rule to have a different action that instead of relying on the magic of fusion/phoenix to give me a vector, I want to explicitly insert matched signature_r attributes into a vector, this is what I thought would work: 1. add a "std::vector sigs;" to foo_parser. 2. Modify the rule declarations and struct definition appropriately: struct foo_parser : boost::spirit::qi::grammar { foo_parser() : foo_parser::base_type(signatures) ..... boost::spirit::qi::rule signatures; 3. Modify signatures rule: signatures = *(signature_r[push_back(ref(sigs), boost::spirit::arg_names::_1)]) ; The problem with #3 is that I get a giant list of errors, the 1st being: 1>c:\code\boost-trunk\boost/spirit/home/phoenix/stl/container/container.hpp(498) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'const unsigned long' to 'const signature &' 1> with 1> [ 1> _Ty=signature 1> ] 1> Reason: cannot convert from 'const unsigned long' to 'const signature' 1> No constructor could take the source type, or constructor overload resolution was ambiguous 1> c:\code\boost-trunk\boost/spirit/home/phoenix/core/detail/function_eval.hpp(135) : see reference to function template instantiation 'void boost::phoenix::stl::push_back::operator ()(C &,const Arg &) const' being compiled 1> with 1> [ 1> T=std::vector, 1> C=std::vector, 1> Arg=const unsigned long 1> ] 1> c:\code\boost-trunk\boost/spirit/home/phoenix/core/detail/composite_eval.hpp(98) : see reference to function template instantiation 'RT boost::phoenix::detail::function_eval<2>::eval>,const boost::spirit::argument>(const Env &,const F &,A0 &,A1 &)' being compiled 1> with 1> [ 1> RT=return_type, 1> Env=boost::phoenix::basic_environment,std::allocator>,std::basic_string,std::allocator>>,boost::fusion::vector,boost::fusion::vector0>,bool>, 1> T=const boost::phoenix::value, 1> _Ty=signature, 1> N=0, 1> F=const boost::phoenix::value, 1> A0=const boost::phoenix::reference>, 1> A1=const boost::spirit::argument<0> 1> ] Any clues?

to lex or not to lex

Jürgen Hofmann — 2008-11-28T19:09:38

Hi, can someone give me a hint, if I want to use a lexer or not? ;-) I was playing a bit with qi and and lex; so for a very simple highly specialised scripting language, what would you recommend? The approach using a lexer seemed to be a bit cleaner and more reusable to me although it seems to require more work to get nice error messages. On the other hand qi seems to be so powerful, that I don't see, why I should need a lexer. For my co-workers I think it's easer to understand something like char_(';') than token(T_SEMICOLON) (although I'm not sure about it). And then again the lexer makes it much easier to "block reserved keywords"... I'm lost. Any recommendations?

[Spirit2]UTF-8

OvermindDL1 — 2008-11-25T07:48:59

So, I have lots of little files I need to parse. However, they are all in UTF-8 and do include characters that span up to 4 bytes in length. Since Spirit2 (or Spirit2x) does not include a char page set for UTF-8 (or Unicode in general), what would be the recommended way to parse this? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

[spirit 2] spirit-lex continuing testing

Carl Barron — 2008-11-25T03:56:03

I forget the exact flax syntax but this should b close enough to explain the problem: /* %% "[ \t\n]+ {} "[^ \t\n]"{return *yytext;} { "[ \t]{} "\n+"{BEGIN BOL_1;} "[^ \t\n]" {return '\0';} // some char that will fail the parse } { "[ \t]"{BEGIN BOL;} .{BEGIN INIYIAL; return *yytext;}// no newlines here!! } */ in english in the initial state it merely eats [skips] [ \t\n] and returns the matched character, in BOL it skips [ \y\n]+ where the last char is a \n. In other words in the defalt state passed " \ta" it returns 'a' in state BOL it returns something the grammar will not parse such as '\0'. " \na" returns "a" in both states " \n a" returns a in initial state and fails in state BOL [returns '\0' for instance then a lex_and_parse()'s grammar can get a bel parser just changing the state of the lexer where a bol is nmeded and it will go back to initial state after the lexer returns its token. I am confused . is this possible, fairly easily? If so thwn the BOL problem is solvable without lazy parsers, just let the lexer do the skipping:) ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Permutation parser with non mandatory perm.items

Ladislav — 2008-11-24T08:03:44

Hi, I tryed make my self permutation parser with possibility to have non obligatory permutation item parsers. Evrithing goes well for me, but i cant compile if i use main parse function with Skipper parser. Evidently i miss somthing in my templates definition. Here is source code for my pmut_p and pi_p types. http://www.nabble.com/file/p20625402/permutation.hpp permutation.hpp If some one have time and understund more then me of templates pls help me :) (Im a template begginer) Here is some grammar for testing: struct test : public grammar { template struct definition { definition(calculator const& ) { a = !ch_p('a'); b = !ch_p('b'); c = ch_p('c'); file = !ch_p('>') >> pmut_p( (pi_p(a), pi_p(b), pi_p(c)) ); BOOST_SPIRIT_DEBUG_RULE(a); BOOST_SPIRIT_DEBUG_RULE(b); BOOST_SPIRIT_DEBUG_RULE(c); BOOST_SPIRIT_DEBUG_RULE(file); } rule a, b, c, file; rule const& start() const { return file; } }; }; this parser should parse phrases: abc, acb, bac, bca, cab, cba, bc, cb, ac, ca, c (a and b are optional) Naturally example with letters is just for test, the intent is to use like pi_p( any parsing rule ) I test it without skipper parser, and it function, problem is when i call parse with skipper parser present. Thx in advance for who will help me find a problem :) ladislav

Help me getting started please
