// This is a Parsing Expression Grammar for Lojban.
// See http://bford.info/packrat/
// 
// All rules have the form:
// 
// 	name = peg_expression
// 
// which means that the grammatical construct "name" is parsed using
// "peg_expression".  
// 
// 1)  Names in lower case are grammatical constructs.
// 2)  Names in UPPER CASE are selma'o (lexeme) names, and are terminals.
// 3)  Concatenation is expressed by juxtaposition with no operator symbol.
// 4)  / represents *ORDERED* alternation (choice).  If the first
//     option succeeds, the others will never be checked.
// 5)  ? indicates that the element to the left is optional.
// 6)  * represents optional repetition of the construct to the left.
// 7)  + represents one_or_more repetition of the construct to the left.
// 8)  () serves to indicate the grouping of the other operators.
//
// Longest match wins.

// How to compile using Node.js: (Added by Masato Hagiwara)

// // load peg.js and the file system module
// > var PEG = require("pegjs")
// > var fs = require("fs")
// // read peg and build a parser
// > var camxes_peg = fs.readFileSync("/path/to/camxes.js.peg").toString();
// > var camxes = PEG.buildParser(camxes_peg, {cache: true});
// // test it
// > camxes.parse("ko'a broda");
// [ 'text',
//   [ 'text_1',
//     [ 'paragraphs', [Object] ] ] ]
// // write to a file
// > fs.writeFileSync("/path/to/camxes.js", camxes.toSource());

// This is a Parsing Expression Grammar for the morphology of Lojban.
// See http://www.pdos.lcs.mit.edu/~baford/packrat/
//
// All rules have the form
//
// name = peg_expression
//
// which means that the grammatical construct "name" is parsed using
// "peg_expression".
//
// 1) Concatenation is expressed by juxtaposition with no operator symbol.
// 2) / represents *ORDERED* alternation (choice). If the first
// option succeeds, the others will never be checked.
// 3) ? indicates that the element to the left is optional.
// 4) * represents optional repetition of the construct to the left.
// 5) + represents one_or_more repetition of the construct to the left.
// 6) () serves to indicate the grouping of the other operators.
// 7) & indicates that the element to the right must follow (but the
// marked element itself does not absorb anything).
