parsing - How can I define an INI file grammar using the BNFC? -

How to write BNF with my label to make INFi Parser for me?

I have yet received the o__O!

  entry point file; Comment "#" ; Token id (letter | numbers | ["-_ '"]] +; Th File :: = [section]; Sect Section: = "[" id "]" [statement]; Bind Statement: = id = "id"; Separator Details "\ n"; Terminator section "";  

---

  [name] #x = 10 y = 20  

---

  Pars succeeded! [Surname] [name (name "name") [bind (id "y") (id "20")] [linerized tree] [name] y = 20  

---

< Pre> [name] x = 10 #y = 20

---

  Pars succeeded! [Abstract syntax] Ine [sect (id "name") [bind (id "x") (id "10")] [alkaline tree] [name] x = 10  

ODO I am stuck ...

I asked a BNFC devs and quoted it here:

Space characters such as Newlines are not well supported in tokens because the hard-wired laser type "Space" in BNFC. The idea is that the spaces can not make sense in "well-behaved" languages, one of the restrictions that has made the BNFC so easy ... but you should solve it using a preprocessor, eg. Pars the input line by line.

For example:

  entry point file; Comment "#" ; Token id (letter | numbers | ["-_ '"]] +; Th File :: = [section]; Sect Section: = "[" id "]" [statement]; Bind Statement: = id = "id"; Separator Details "//"; Terminator stream "//";  

---

Read:

  [name] x = 10 y = 20  

---

preprocess :

  [name] // x = 10 // y = 20 //  

---

Pars:

 < Code (id "name") [bind (id "x") (id "10"), bind (id "Y") (id "20")]]   < "Name") [bind (id "x") (id "0"), bind (id "y"):  (id "0")]]  

---

Type:

  [name] // x = 0 // y = 0 //  

---

post process: < / P>

  [name] x = 0 y = 0  

(not checked, don does not know that it works, Irf give you an idea!)
