@ -10,6 +10,8 @@ Creating a new target involves the following key elements:
1. Create *X*.stg in directory tool/resources/org/antlr/v4/tool/templates/codegen/*X*/*X*.stg. This is a [StringTemplate](http://www.stringtemplate.org/) group file (`.stg`) that tells ANTLR how to express all of the parsing elements needed to generate code. You will see templates called `ParserFile`, `Parser`, `Lexer`, `CodeBlockForAlt`, `AltBlock`, etc... Each of these must be described how to build the indicated chunk of code. Your best bet is to find the closest existing target, copy that template file, and tweak to suit.
1. Create a runtime library to support the parsers generated by ANTLR. Under directory runtime/*X*, you are in complete control of the directory structure as dictated by common usage of that target language. For example, Java has: `runtime/Java/lib` and `runtime/Java/src` directories. Under `src`, you will find a directory structure for package `org.antlr.v4.runtime` and below.
1. Create a template file for runtime tests. All you have to do is provide a few templates that indicate how to print values and declare variables. Our runtime test mechanism in dir `runtime-testsuite` will automatically generate code using these templates for each target and check the test results. It needs to know how to define various class fields, compare members and so on. You must create a *X*.test.stg file underneath [runtime-testsuite/resources/org/antlr/v4/test/runtime](https://github.com/antlr/antlr4/tree/master/runtime-testsuite/resources/org/antlr/v4/test/runtime). Again, your best bet is to copy the templates from the closest language to your target and tweak it to suit.
1. Create test files under [/runtime-testsuite/test/org/antlr/v4/test/runtime](https://github.com/antlr/antlr4/tree/master/runtime-testsuite/test/org/antlr/v4/test/runtime). They will load defined test cases in each test descriptor. Also add the `/runtime-testsuite/test/org/antlr/v4/test/runtime/X/BaseXTest.java` which defines how test cases will execute and output.
1. Create/edit shell scripts in [/.travis](https://github.com/antlr/antlr4/blob/master/.travis) and [/appveyor.yml](https://github.com/antlr/antlr4/blob/master/appveyor.yml) to run tests in CI pipelines.

# ANTLR4 Runtime for Dart
Notice: Dart target may generate code incompatible with Dart 2.9 sound null safety. Please set the minimum SDK constraint to 2.8.4 or lower if such violation is found. Contributions are welcomed.
### First steps
#### 1. Install ANTLR4
[The getting started guide](https://github.com/antlr/antlr4/blob/master/doc/getting-started.md)
should get you started.
#### 2. Install the Dart ANTLR runtime
Each target language for ANTLR has a runtime package for running parser
generated by ANTLR4. The runtime provides a common set of tools for using your parser.
Install the runtime with the same version as the main ANTLR tool:
Add this to your package's pubspec.yaml file:
```yaml
...
dependencies:
antlr4: <ANTLR version>
...
```
#### 3. Generate your parser
You use the ANTLR4 "tool" to generate a parser. These will reference the ANTLR
runtime, installed above.
Suppose you're using a UNIX system and have set up an alias for the ANTLR4 tool
as described in [the getting started guide](https://github.com/antlr/antlr4/blob/master/doc/getting-started.md).
To generate your Dart parser, run the following command:
```shell script
antlr4 -Dlanguage=Dart MyGrammar.g4
```
For a full list of antlr4 tool options, please visit the
[tool documentation page](https://github.com/antlr/antlr4/blob/master/doc/tool-options.md).
### Complete example
Suppose you're using the JSON grammar from https://github.com/antlr/grammars-v4/tree/master/json.
Then, invoke `antlr4 -Dlanguage=Dart JSON.g4`. The result of this is a
collection of `.dart` including:
* JsonLexer.dart
* JsonParser.dart
* JsonBaseListener.dart

}

JSONLexer.checkVersion();
JSONParser.checkVersion();
final input = await InputStream.fromPath(args[0]);
final lexer = JSONLexer(input);
final tokens = CommonTokenStream(lexer);
final parser = JSONParser(tokens);
parser.addErrorListener(DiagnosticErrorListener());
parser.buildParseTree = true;
final tree = parser.json();
ParseTreeWalker.DEFAULT.walk(TreeShapeListener(), tree);
}
```
Create a `example.json` file:
```json
{"a":1}
```
Parse the input file:
```shell script
dart bin/main.dart example.json
```
The expected output is:
```
{"a":1}
{"a":1}
{"a":1}
"a":1

XPath works great when you need to find specific nodes, possibly in certain contexts. The context is limited to the parents on the way to the root of the tree. For example, if you want to find all ID nodes, use path `//ID`. If you want all variable declarations, you might use path `//vardecl`. If you only want fields declarations, then you can use some context information via path `/classdef/vardecl`, which would only find vardecls that our children of class definitions. You can merge the results of multiple XPath `findAll()`s simulating a set union for XPath. The only caveat is that the order from the original tree is not preserved when you union multiple `findAll()` sets.

ANTLR is really two things: a tool that translates your grammar to a parser/lexer in Java (or other target language) and the runtime needed by the generated parsers/lexers. Even if you are using the ANTLR Intellij plug-in or ANTLRWorks to run the ANTLR tool, the generated code will still need the runtime library.
The first thing you should do is probably download and install a development tool plug-in. Even if you only use such tools for editing, they are great. Then, follow the instructions below to get the runtime environment available to your system to run generated parsers/lexers. In what follows, I talk about antlr-4.7.1-complete.jar, which has the tool and the runtime and any other support libraries (e.g., ANTLR v4 is written in v3).

NodeJS together with a packaging tool is now the preferred development path, developers are encouraged to follow it.
## What about modules?
Starting with version 8.1, Antlr4 JavaScript runtime follows esm semantics (see https://tc39.es/ecma262/#sec-modules for details)
Generated lexers, parsers, listeners and visitors also follow this new standard.
If you have used previous versions of the runtime, you will need to migrate and make your parser a module.
## How to create a JavaScript lexer or parser?
@ -55,32 +62,20 @@ You can get [information on webpack here](https://webpack.github.io).
The steps to create your parsing code are the following:
- generate your lexer, parser, listener and visitor using the antlr tool
- write your parse tree handling code by providig your custom listener or visitor, and associated code, using 'require' to load antlr.
- write your parse tree handling code by providing your custom listener or visitor, and associated code, using 'require' to load antlr.
- create an index.js file with the entry point to your parsing code (or several if required).
- test your parsing logic thoroughly using node.js
You are now ready to bundle your parsing code as follows:
- following webpack specs, create a webpack.config file
- in the webpack.config file, exclude node.js only modules using: node: { module: "empty", net: "empty", fs: "empty" }
- For Webpack version 5,
- in the `webpack.config` file, exclude node.js only modules using: `resolve: { fallback: { fs: false } }`
- For older versions of Webpack,
- in the `webpack.config` file, exclude node.js only modules using: `node: { module: "empty", net: "empty", fs: "empty" }`
- from the cmd line, navigate to the directory containing webpack.config and type: webpack
This will produce a single js file containing all your parsing code. Easy to include in your web pages!
If you can't use webpack, you can use the lib/require.js script which implements the Node.js 'require' function in brwsers.
This script is provided by Torben Haase, and is NOT part of ANTLR JavaScript runtime.
Assuming you have, at the root of your web site, both the 'antlr4' directory and a 'lib' directory with 'require.js' inside it, all you need to put in your HTML header is the following:
```xml
<script src='lib/require.js'>
<script>
var antlr4 = require('antlr4/index');
</script>
```
This will load the runtime asynchronously.

Let's suppose your MyGrammar grammar comprises 2 rules: "key" and "value". The antlr4 tool will have generated the following listener:
```javascript
MyGrammarListener = function(ParseTreeListener) {
// some code here
}
// some code here
MyGrammarListener.prototype.enterKey = function(ctx) {};
MyGrammarListener.prototype.exitKey = function(ctx) {};
MyGrammarListener.prototype.enterValue = function(ctx) {};

class MyGrammarListener extends ParseTreeListener {
constructor() {
super();
}
enterKey(ctx) {}
exitKey(ctx) {}
enterValue(ctx) {}
exitValue(ctx) {}
}
```
In order to provide custom behavior, you might want to create the following class:
```javascript
var KeyPrinter = function() {
MyGrammarListener.call(this); // inherit default listener
return this;
};
class KeyPrinter extends MyGrammarListener {
// continue inheriting default listener
KeyPrinter.prototype = Object.create(MyGrammarListener.prototype);
KeyPrinter.prototype.constructor = KeyPrinter;
// override default listener behavior
KeyPrinter.prototype.exitKey = function(ctx) {
console.log("Oh, a key!");
};
// override default listener behavior
exitKey(ctx) {
console.log("Oh, a key!");
}
}
```
In order to execute this listener, you would simply add the following lines to the above code:
```javascript
...
tree = parser.StartRule() // only repeated here for reference
var printer = new KeyPrinter();
...
tree = parser.StartRule() // only repeated here for reference
const printer = new KeyPrinter();
