I\'m using QI and Phoenix, and I want to write a small grammar that returns 4 bools which are to be used as arguments for a function call inside a semantic action.
I\'m running into frequent segfaults with my Spirit Qi parser. After spending days to debug the issue (I found the stacktraces impossible to grok) I decided to trim it down to a minimal example. Can
How would I declare a semantic action that calls a free function that doesn\'t use the attribute the rule/parser returned?
--edit -- Solved the question : a comment on the last sidenote would be helpfull. Also comments on phoenix::bind overload handling would be helpfull (in my answer).
This is probably a pathetically easy question, especially since I\'ve been successfully using QI to parse simple structures for a while now, and probably should already know the answer, but 开发者_如何
Basically I\'m doing an expression parser. As I\'m in need of as good as possible performance, and according to the documentation construction of a grammar can be rather slow, I\'d lik开发者_运维知识库
I have a grammar that has, up until now, been using the standard boost::spirit::ascii::space/boost::spirit::ascii::space_type skipper.
I want to parse a vector of the following struct: BOOST_FUSION_ADAPT_STRUCT( event_model::OTNDescriptor,
I want to write a function in C++ to replace C\'s sscanf that assigns the matches to iterator. Basically, I want something like:
Below is a fully self-contained example.The problem appears to be lines 84-89 - if those lines are commented out, the example compiles. What I\'m trying to parse is each line of a file, with five colo
