bison - Using yacc precedence for rules with no terminals, only non-terminals -


Someone can help me This is my rule on: 

  e: T_NUM {$$ = Mk_ant ($ 1);} | T_POP E [l] {$$ = Mk_Ap (Mk_op (POP), $ l);} | T_NEXT E [l] {$$ = MK_Ap (MK_op (NEXT), $ l);} | "{" E [x] "," e [y] "}" {$$ = mk_point ($ x, $ y);} | E T_PLUS E {$$ = Mk_Ap (Mk_Ap (Mk_op (plus), $ 1), $ 3);} | E T_MINUS E {$$ = MK_Ap (Mk_Ap (MINUS), $ 1), $ 3);} | E T_DIV E {$$ = MK_Ap (Mk_Ap (Mk_op (DIV), $ 1), $ 3);} | E T_MULT E {$$ = MK_Ap (Mk_Ap (MKTOP (MULT), $ 1), $ 3);} | E T_LEQ E {$$ = MK_Ap (Mk_Ap (LEQ, $ 1), $ 3);} | E T_LEE {$$ = MK_Ap (Mk_app (Mk_op ($ 1), $ 3);} | E T_GEQ E {$$ = MK_Ap (Mk_Ap (MKAOP), $ 1), $ 3);} | E T_GE E {$$ = MK_Ap (Mk_Ap (Mk_op (GE), $ 1), $ 3);} | E T_OR E {$$ = Mk_Ap (Mk_app (MK_OP, $ 1), $ 3);} | E T_AND E {$$ = Mk_Ap (Mk_app (AND, $ 1), $ 3);} | T_ID {$$ = MK_ID ($ 1);} / * RECONCISE DIIIPUTER and variable variable * / | E T_EQ E {$$ = MK_Ap (Mk_Ap (Mk_op (EQ), $ 1), $ 3);} | T_NOT e [expr] {$$ = mk_app (mk_op (not), $ expr)}} T_FUN T_ID [var] arg_list [expr] {$$ = mk_fun ($ var, $ expr); Env = push_rec_env ($ var, $$, env);} / * DADDESS DE FANSIONS * / | T_LET T_ID [x] T_EQUAL E [AGG] T_IN E [XP] {$$ = MK_Ap (Mk_fan ($ x, $ EXP), $ arg); Env = push_rec_env ($ x, $$, env);} / * fonts in * / | E [exp] T_WHERE T_ID [x] T_EQUAL E [AG] {$$ = MK_Ap (Mk_fone ($ x, $ EXP), $ arg); env = push_rec_env ($ x, $$, env);} / * function WHERE * / | TIIF E [Cond] T_ATHNE [TO_BR] TILESEE [AAIBiB] {$$ = MKCand ($ CAD, $ RE _ BR, AADAB);} '[' List [L] ']' {$$ = $ l;} / * OP List list * / | E [EXPA] T_PUSH A [L] {$$ = MK_Ap (Mk_Ap (Mk_op (push), $ EXP), $ l);} | '(F.Gear [Funny] E [AG]' '$$ = MK_Ep ($ fun, $ AGR);} / * Exxoning de phonics a plural variables * / |' ('E') '{$$ = $ 2;} * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * I would like to remove, but it produces many conflicts if someone can give me a hand that how can I work out this syntax without brackets for information:  
  f_arg: e {$$ = $ 1;} | f_arg [fun] e [ag] {$$ = mk_app ($ fun, $ agr);}  < / p> 
  
  
  
  
  
 
 
 The problem is that the unknown function application in relation to all your binary information and prefixes is unclear - an input such as  ab + c  to  (ab) + c Can be parsed as  or  a (b + c)  as there is no token in the function application, so the usual yacc / bison privacy rule additional assistance Without work, will not work for it.  
 Thinking that you want to give the Function app the highest priority (General Case, I), then you can do this work with some extra work.  
 Add the following authorization rule at the end of your list (top priority):  
 % left FUNCTION_APPLICATION T_NUM T_ID '{' '('   
 Create your own function rule:  
  | e [fun] e [arg]% prec FUNCTION_APPLICATION {$$ = mk_app ($ Fun, $ arg);}   
 What else do you have in grammar, you may need to add some more tokens in the preceding rules and / or rearrange some things. Prioritize each token in the first (e) Are needed , And if its preference for the function is different from its predecessor for other uses, then things will not work (only one priority as each token). High Priority, from everything else, things can be resolved

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
