+PEG.js is currently maintained by Futago-za Ryuu.
+Since it's inception in 2010, PEG.js was
+maintained by David Majda (@dmajda),
+until May 2017.
+
+The Bower package is maintained by
+Michel Krämer
+(@michelkraemer).
+
+You are welcome to contribute code. Unless your contribution is really
+trivial you should get in touch with me first — this can prevent wasted
+effort on both sides. You can send code both as a patch or a GitHub pull
+request.
+
+Note that PEG.js is still very much work in progress. There are no
+compatibility guarantees until version 1.0.

+
+
+
+Installation
+
+Node.js
+
+To use the pegjs command, install PEG.js globally:
+
+$ npm install -g pegjs
+
+To use the JavaScript API, install PEG.js locally:
+
+$ npm install pegjs
+
+If you need both the pegjs command and the JavaScript API,
+install PEG.js both ways.
+
+Browser
+
+Download the PEG.js library
+(regular or minified version) or install it using Bower:
+
+$ bower install pegjs
+
+Generating a Parser
+
+PEG.js generates parser from a grammar that describes expected input and can
+specify what the parser returns (using semantic actions on matched parts of the
+input). Generated parser itself is a JavaScript object with a simple API.
+
+Command Line
+
+To generate a parser from your grammar, use the pegjs
+command:
+
+$ pegjs arithmetics.pegjs
+
+This writes parser source code into a file with the same name as the grammar
+file but with “.js” extension. You can also specify the output file
+explicitly:
+
+$ pegjs -o arithmetics-parser.js arithmetics.pegjs
+
+If you omit both input and output file, standard input and output are
+used.
+
+By default, the generated parser is in the Node.js module format. You can
+override this using the --format option.
+
+You can tweak the generated parser with several options:
+
+
+ --allowed-start-rules- Comma-separated list of rules the parser will be allowed to start parsing
+ from (default: the first rule in the grammar).
+
+ --cache- Makes the parser cache results, avoiding exponential parsing time in
+ pathological cases but making the parser slower.
+
+ --dependency- Makes the parser require a specified dependency (can be specified multiple
+ times).
+
+ --export-var- Name of a global variable into which the parser object is assigned to when
+ no module loader is detected.
+
+ --extra-options- Additional options (in JSON format) to pass to
+
peg.generate.
+
+ --extra-options-file- File with additional options (in JSON format) to pass to
+
peg.generate.
+
+ --format- Format of the generated parser:
amd, commonjs,
+ globals, umd (default: commonjs).
+
+ --optimize- Selects between optimizing the generated parser for parsing speed
+ (
speed) or code size (size) (default:
+ speed)
+
+ --plugin- Makes PEG.js use a specified plugin (can be specified multiple
+ times).
+
+ --trace- Makes the parser trace its progress.
+
+
+JavaScript API
+
+In Node.js, require the PEG.js parser generator module:
+
+var peg = require("pegjs");
+
+In browser, include the PEG.js library in your web page or application using
+the <script> tag. If PEG.js detects an AMD loader, it will
+define itself as a module, otherwise the API will be available in the
+peg global object.
+
+To generate a parser, call the peg.generate method and pass your
+grammar as a parameter:
+
+var parser = peg.generate("start = ('a' / 'b')+");
+
+The method will return generated parser object or its source code as a string
+(depending on the value of the output option — see below). It will
+throw an exception if the grammar is invalid. The exception will contain
+message property with more details about the error.
+
+You can tweak the generated parser by passing a second parameter with an
+options object to peg.generate. The following options are
+supported:
+
+
+ allowedStartRules- Rules the parser will be allowed to start parsing from (default: the first
+ rule in the grammar).
+
+ cache- If
true, makes the parser cache results, avoiding exponential
+ parsing time in pathological cases but making the parser slower (default:
+ false).
+
+ dependencies- Parser dependencies, the value is an object which maps variables used to
+ access the dependencies in the parser to module IDs used to load them; valid
+ only when
format is set to "amd",
+ "commonjs", or "umd" (default:
+ {}).
+
+ exportVar- Name of a global variable into which the parser object is assigned to when
+ no module loader is detected; valid only when
format is set to
+ "globals" or "umd" (default:

+ a string (default: "parser").
+
+ plugins- Plugins to use.
+
+ trace- Makes the parser trace its progress (default:
false).
+
+
+Using the Parser
+
+Using the generated parser is simple — just call its parse
+method and pass an input string as a parameter. The method will return a parse
+result (the exact value depends on the grammar used to generate the parser) or
+throw an exception if the input is invalid. The exception will contain
+location, expected, found and
+message properties with more details about the error.
+
+parser.parse("abba"); // returns ["a", "b", "b", "a"]
+
+parser.parse("abcd"); // throws an exception
+
+You can tweak parser behavior by passing a second parameter with an options
+object to the parse method. The following options are
+supported:
+
+
+ startRule- Name of the rule to start parsing from.
+
+ tracer- Tracer to use.
+
+
+Parsers can also support their own custom options.
+
+Grammar Syntax and Semantics
+
+The grammar syntax is similar to JavaScript in that it is not line-oriented
+and ignores whitespace between tokens. You can also use JavaScript-style
+comments (// ... and /* ... */).
+
+Let's look at example grammar that recognizes simple arithmetic expressions
+like 2*(3+4). A parser generated from this grammar computes their
+values.
+
+start
+ = additive
+
+additive
+ = left:multiplicative "+" right:additive { return left + right; }
+ / multiplicative
+
+multiplicative
+ = left:primary "*" right:multiplicative { return left * right; }
+ / primary
+
+primary
+ = integer
+ / "(" additive:additive ")" { return additive; }
+
+integer "integer"
+ = digits:[0-9]+ { return parseInt(digits.join(""), 10); }
+
+On the top level, the grammar consists of rules (in our example,
+there are five of them). Each rule has a name (e.g.
+integer) that identifies the rule, and a parsing
+expression (e.g. digits:[0-9]+ { return parseInt(digits.join(""),
+10); }) that defines a pattern to match against the input text and
+possibly contains some JavaScript code that determines what happens when the
+pattern matches successfully. A rule can also contain human-readable
+name that is used in error messages (in our example, only the
+integer rule has a human-readable name). The parsing starts at the
+first rule, which is also called the start rule.
+
+A rule name must be a JavaScript identifier. It is followed by an equality
+sign (“=”) and a parsing expression. If the rule has a human-readable name, it
+is written as a JavaScript string between the name and separating equality sign.
+Rules need to be separated only by whitespace (their beginning is easily
+recognizable), but a semicolon (“;”) after the parsing expression is
+allowed.
+
+The first rule can be preceded by an initializer — a piece of
+JavaScript code in curly braces (“{” and “}”). This code is executed before the
+generated parser starts parsing. All variables and functions defined in the
+initializer are accessible in rule actions and semantic predicates. The code
+inside the initializer can access options passed to the parser using the
+options variable. Curly braces in the initializer code must be
+balanced. Let's look at the example grammar from above using a simple
+initializer.
+
+{
+ function makeInteger(o) {
+ return parseInt(o.join(""), 10);
+ }
+}
+
+start
+ = additive
+
+additive
+ = left:multiplicative "+" right:additive { return left + right; }
+ / multiplicative
+
+multiplicative
+ = left:primary "*" right:multiplicative { return left * right; }
+ / primary
+
+primary
+ = integer
+ / "(" additive:additive ")" { return additive; }
+
+integer "integer"
+ = digits:[0-9]+ { return makeInteger(digits); }
+
+The parsing expressions of the rules are used to match the input text to the
+grammar. There are various types of expressions — matching characters or
+character classes, indicating optional parts and repetition, etc. Expressions
+can also contain references to other rules. See detailed
+description below.
+
+If an expression successfully matches a part of the text when running the
+generated parser, it produces a match result, which is a JavaScript
+value. For example:
+
+
+ - An expression matching a literal string produces a JavaScript string
+ containing matched text.
+
+ - An expression matching repeated occurrence of some subexpression produces
+ a JavaScript array with all the matches.
+
+
+The match results propagate through the rules when the rule names are used in
+expressions, up to the start rule. The generated parser returns start rule's
+match result when parsing is successful.
+
+One special case of parser expression is a parser action — a
+piece of JavaScript code inside curly braces (“{” and “}”) that takes match
+results of some of the the preceding expressions and returns a JavaScript value.
+This value is considered match result of the preceding expression (in other
+words, the parser action is a match result transformer).
+
+In our arithmetics example, there are many parser actions. Consider the
+action in expression digits:[0-9]+ { return parseInt(digits.join(""), 10);
+}. It takes the match result of the expression [0-9]+, which is an array
+of strings containing digits, as its parameter. It joins the digits together to
+form a number and converts it to a JavaScript number object.
+
+Parsing Expression Types
+
+There are several types of parsing expressions, some of them containing
+subexpressions and thus forming a recursive structure:
+
+
+ "literal"
'literal'-
+
Match exact literal string and return it. The string syntax is the same
+ as in JavaScript. Appending i right after the literal makes the
+ match case-insensitive.
+
+
+ .-
+
Match exactly one character and return it as a string.
+
+
+ [characters]-
+
Match one character from a set and return it as a string. The characters
+ in the list can be escaped in exactly the same way as in JavaScript string.
+ The list of characters can also contain ranges (e.g. [a-z]
+ means “all lowercase letters”). Preceding the characters with ^
+ inverts the matched set (e.g. [^a-z] means “all character but
+ lowercase letters”). Appending i right after the literal makes
+ the match case-insensitive.
+
+
+ rule-
+
Match a parsing expression of a rule recursively and return its match
+ result.
+
+
+ ( expression )-
+
Match a subexpression and return its match result.
+
+
+ expression *-
+
Match zero or more repetitions of the expression and return their match
+ results in an array. The matching is greedy, i.e. the parser tries to match
+ the expression as many times as possible. Unlike in regular expressions,
+ there is no backtracking.
+
+
+ expression +-
+
Match one or more repetitions of the expression and return their match
+ results in an array. The matching is greedy, i.e. the parser tries to match
+ the expression as many times as possible. Unlike in regular expressions,
+ there is no backtracking.
+
+
+ expression ?-
+
Try to match the expression. If the match succeeds, return its match
+ result, otherwise return null. Unlike in regular expressions,
+ there is no backtracking.
+
+
+ & expression-
+
Try to match the expression. If the match succeeds, just return
+ undefined and do not consume any input, otherwise consider the
+ match failed.
+
+
+ ! expression-
+
Try to match the expression. If the match does not succeed, just return
+ undefined and do not consume any input, otherwise consider the
+ match failed.
+
+
+ & { predicate }-
+
The predicate is a piece of JavaScript code that is executed as if it was
+ inside a function. It gets the match results of labeled expressions in
+ preceding expression as its arguments. It should return some JavaScript
+ value using the return statement. If the returned value
+ evaluates to true in boolean context, just return
+ undefined and do not consume any input; otherwise consider the
+ match failed.
+
+ The code inside the predicate can access all variables and functions
+ defined in the initializer at the beginning of the grammar.
+
+ The code inside the predicate can also access location information using
+ the location function. It returns an object like this:
+
+ {
+ start: { offset: 23, line: 5, column: 6 },
+ end: { offset: 23, line: 5, column: 6 }
+}
+
+ The start and end properties both refer to the
+ current parse position. The offset property contains an offset
+ as a zero-based index and line and column
+ properties contain a line and a column as one-based indices.
+
+ The code inside the predicate can also access options passed to the
+ parser using the options variable.
+
+ Note that curly braces in the predicate code must be balanced.
+
+
+ ! { predicate }-
+
The predicate is a piece of JavaScript code that is executed as if it was
+ inside a function. It gets the match results of labeled expressions in
+ preceding expression as its arguments. It should return some JavaScript
+ value using the return statement. If the returned value

+ undefined and do not consume any input; otherwise consider the

+}
+

+ current parse position. The offset property contains an offset
+ as a zero-based index and line and column
+ properties contain a line and a column as one-based indices.
+
+ The code inside the predicate can also access options passed to the
+ parser using the options variable.
+
+ Note that curly braces in the predicate code must be balanced.
+
+
+ $ expression-
+
Try to match the expression. If the match succeeds, return the matched
+ text instead of the match result.
+
+
+ label : expression-
+
Match the expression and remember its match result under given label.
+ The label must be a JavaScript identifier.
+
+ Labeled expressions are useful together with actions, where saved match
+ results can be accessed by action's JavaScript code.
+
+
+ expression1 expression2 ... expressionn-
+
Match a sequence of expressions and return their match results in an array.
+
+
+ expression { action }-
+
Match the expression. If the match is successful, run the action,
+ otherwise consider the match failed.
+
+ The action is a piece of JavaScript code that is executed as if it was
+ inside a function. It gets the match results of labeled expressions in
+ preceding expression as its arguments. The action should return some
+ JavaScript value using the return statement. This value is
+ considered match result of the preceding expression.
+
+ To indicate an error, the code inside the action can invoke the
+ expected function, which makes the parser throw an exception.
+ The function takes two parameters — a description of what was expected at
+ the current position and optional location information (the default is what
+ location would return — see below). The description will be
+ used as part of a message of the thrown exception.
+
+ The code inside an action can also invoke the error
+ function, which also makes the parser throw an exception. The function takes
+ two parameters — an error message and optional location information (the
+ default is what location would return — see below). The message
+ will be used by the thrown exception.
+
+ The code inside the action can access all variables and functions defined
+ in the initializer at the beginning of the grammar. Curly braces in the
+ action code must be balanced.
+
+ The code inside the action can also access the text matched by the
+ expression using the text function.
+
+ The code inside the action can also access location information using the
+ location function. It returns an object like this:
+
+ {
+ start: { offset: 23, line: 5, column: 6 },
+ end: { offset: 25, line: 5, column: 8 }
+}
+
+ The start property refers to the position at the beginning
+ of the expression, the end property refers to position after
+ the end of the expression. The offset property contains an
+ offset as a zero-based index and line and column
+ properties contain a line and a column as one-based indices.
+
+ The code inside the action can also access options passed to the parser
+ using the options variable.
+
+ Note that curly braces in the action code must be balanced.
+
+
+ expression1 / expression2 / ... / expressionn-
+
Try to match the first expression, if it does not succeed, try the second
+ one, etc. Return the match result of the first successfully matched
+ expression. If no expression matches, consider the match failed.
+
+
+
