Thank you for proposing a contribution to the ANTLR project. In order to accept changes from the outside world, all contributors most "sign" the [contributors.txt](https://github.com/antlr/antlr4/blob/master/contributors.txt) contributors certificate of origin. It's an unfortunate reality of today's fuzzy and bizarre world of open-source ownership.

To start with, let's load ANTLR and your parser, listener etc..
The preferred approach for loading parser code is to bundle your parser, [as described here](javascript-target.md).
You can then load it as part of the importScripts instruction at the start of your worker code.
Another approach is to load it using 'require'. Easy, since you could write:
```js
var antlr4 = require('antlr4/index');
```
This may work, but it's actually unreliable. The reason is that the require function used by ANTLR, which exactly mimics the NodeJS require function, uses a different syntax than the require function that comes with ACE. So we need to bring in a require function that conforms to the NodeJS syntax. I personally use one that comes from Torben Haase's Honey project, which you can find here. But hey, now we're going to have 2 'require' functions not compatible with each other! Indeed, this is why you need to take special care, as follows:

Please note the try-finally construct. ANTLR uses 'require' synchronously so it's perfectly safe to ignore the ACE 'require' while running ANTLR code. ACE itself does not guarantee synchronous execution, so you are much safer always switching 'require' back to 'ace_require'.
Now detecting deep syntax errors in your code is a task for your ANTLR listener or visitor or whatever piece of code you've delegated this to. We're not going to describe this here, since it would require some knowledge of your language. However, detecting grammar syntax errors is something ANTLR does beautifully (isn't that why you went for ANTLR in the first place?). So what we will illustrate here is how to report grammar syntax errors. I have no doubt that from there, you will be able to extend the validator to suit your specific needs.
Whenever ANTLR encounters an unexpected token, it fires an error. By default, the error is routed to an error listener which simply writes to the console.
What we need to do is replace this listener by our own listener, se we can route errors to the ACE editor. First, let's create such a listener:

You know what? That's it! You now have an ACE editor that does syntax validation using ANTLR! I hope you find this useful, and simple enough to get started.
What I did not address here is packaging, not something I'm an expert at. The good news is that it makes development simple, since I don't have to run any compilation process. I just edit my code, reload my editor page, and check how it goes.
Now wait, hey! How do you debug this? Well, as usual, using Chrome, since neither Firefox or Safari are able to debug worker code. What a shame...

The grammars are strings representing StringTemplates (`ST` objects) so `<writeln("$text")>` will get replace when the unit test file is generated (`Test.java`, `Test.cs`, ...). The `writeln` template must be defined per target. Here are all of the
[Target templates for runtime tests](https://github.com/antlr/antlr4/tree/master/runtime-testsuite/resources/org/antlr/v4/test/runtime/templates).
## Requirements
In order to perform the tests on all target languages, you need to have the following languages installed:
* `mono` (e.g., `brew install mono`) on non-Windows boxes (on Windows it uses the Microsoft .net stack). Also must [`xbuild` the runtime](https://github.com/antlr/antlr4/blob/master/doc/releasing-antlr.md) before tests will run; see below
* `nodejs`
* Python 2.7
* Python 3.5
* Go
* Swift 3 (via XCode 8.x) tested currently only osx
* clang (for C++ target)
*
To **install into local repository** `~/.m2/repository/org/antlr`, do this:
```bash
$ export MAVEN_OPTS="-Xmx1G" # don't forget this on linux
$ mvn install -DskipTests=true # make sure all artifacts are visible on this machine
```
Now, make sure C# runtime is built and installed locally.
```bash
cd ~/antlr/code/antlr4/runtime/CSharp/runtime/CSharp
# kill previous ones manually as "xbuild /t:Clean" didn't seem to do it
rm Antlr4.Runtime/bin/net20/Release/Antlr4.Runtime.dll
rm Antlr4.Runtime/obj/net20/Release/Antlr4.Runtime.dll
# build
xbuild /p:Configuration=Release Antlr4.Runtime/Antlr4.Runtime.mono.csproj
```
C++ test rig automatically builds C++ runtime during tests. Others don't need a prebuilt lib.
## Running the runtime tests
A single test rig is sufficient to test all targets against all descriptors using the [junit parameterized tests](https://github.com/junit-team/junit4/wiki/parameterized-tests) mechanism. But, that is inconvenient because we often want to test just a single target or perhaps even just a single test within a single group of a single target. I have automatically generated a bunch of

There are a couple of things that only the C++ ANTLR target has to deal with. They are described here.
### Build Aspects
The code generation (by running the ANTLR4 jar) allows to specify 2 values you might find useful for better integration of the generated files into your application (both are optional):
* A **namespace**: use the **`-package`** parameter to specify the namespace you want.
* An **export macro**: especially in VC++ extra work is required to export your classes from a DLL. This is usually accomplished by a macro that has different values depending on whether you are creating the DLL or import it. The ANTLR4 runtime itself also uses one for its classes:
```c++
#ifdef ANTLR4CPP_EXPORTS
#define ANTLR4CPP_PUBLIC __declspec(dllexport)
#else
#ifdef ANTLR4CPP_STATIC
#define ANTLR4CPP_PUBLIC
#else
#define ANTLR4CPP_PUBLIC __declspec(dllimport)
#endif
#endif
```
Just like the `ANTLR4CPP_PUBLIC` macro here you can specify your own one for the generated classes using the **`-DexportMacro=...`** command-line parameter or
grammar option `options {exportMacro='...';}` in your grammar file.
In order to create a static lib in Visual Studio define the `ANTLR4CPP_STATIC` macro in addition to the project settings that must be set for a static library (if you compile the runtime yourself).
For gcc and clang it is possible to use the `-fvisibility=hidden` setting to hide all symbols except those that are made default-visible (which has been defined for all public classes in the runtime).
### Memory Management
Since C++ has no built-in memory management we need to take extra care. For that we rely mostly on smart pointers, which however might cause time penalties or memory side effects (like cyclic references) if not used with care. Currently however the memory household looks very stable. Generally, when you see a raw pointer in code consider this as being managed elsewehere. You should never try to manage such a pointer (delete, assign to smart pointer etc.).

<script src='lib/myscript.js'>
```
In order to avoid having to do this, and also to have the exact same code for browsers and Node.js, we rely on a script which provides the equivalent of the Node.js 'require' function.
To avoid having doing this, the preferred approach is to bundle antlr4 with your parser code, using webpack.
This script is provided by Torben Haase, and is NOT part of ANTLR JavaScript runtime, although the runtime heavily relies on it. Please note that syntax for 'require' in NodeJS is different from the one implemented by RequireJS and similar frameworks.
You can get [information on webpack here](https://webpack.github.io).
So in short, 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:
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.
- 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" }
- from the cmd line, nag-vigate 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:

### CSharp
*Publishing to Nuget from Linux/MacOSX*
**Getting ready to run Nuget**
Of course you need Mono and `nuget` to be installed. On mac:
```bash
brew install mono
brew install nuget
```
Or, you can [download nuget.exe](https://dist.nuget.org/win-x86-commandline/latest/nuget.exe).
From the shell on mac, you can check all is ok by typing
```bash
nuget
```
This should display the nuget help.
**Creating the assembly**
```bash
$ cd runtime/CSharp/runtime/CSharp/Antlr4.Runtime
$ xbuild /p:Configuration=Release Antlr4.Runtime.mono.csproj
...
Copying file from '/Users/parrt/antlr/code/antlr4/runtime/CSharp/runtime/CSharp/Antlr4.Runtime/obj/net20/Release/Antlr4.Runtime.Standard.dll' to '/Users/parrt/antlr/code/antlr4/runtime/CSharp/runtime/CSharp/Antlr4.Runtime/lib/Release/Antlr4.Runtime.Standard.dll'
Done building project "/Users/parrt/antlr/code/antlr4/runtime/CSharp/runtime/CSharp/Antlr4.Runtime/Antlr4.Runtime.mono.csproj".
```
Alternately, you may want to build ANTLR using Xamarin Studio Community (free).
**Packaging for NuGet**
```bash
cd runtime/CSharp/runtime/CSharp
```
which is where the `Package.nuspec` file resides.
Type the following command:
```bash
$ nuget pack Package.nuspec
Attempting to build package from 'Package.nuspec'.
Successfully created package '/Users/parrt/antlr/code/antlr4/runtime/CSharp/runtime/CSharp/Antlr4.Runtime.Standard.4.6.0.nupkg'.
```
This should display: Successfully created package *&lt;package-path>*
**Publishing to NuGet**
You need to be a NuGet owner for "ANTLR 4 Standard Runtime"
As a registered NuGet user, you can then manually upload the package spec here (`runtime/CSharp/runtime/CSharp/Package.nuspec`): [https://www.nuget.org/packages/manage/upload](https://www.nuget.org/packages/manage/upload)
Alternately, you can publish from the cmd line. You need to get your NuGet key from [https://www.nuget.org/account#](https://www.nuget.org/account#) and then from the cmd line, you can then type:
```bash
nuget push Antlr4.Runtime.Standard.<version>.nupkg <your-key> -Source https://www.nuget.org/api/v2/package

installed.[The getting started guide](getting-started.md) should get
you started.

[tool documentation page](tool-options.md).
#### 3. Get the Swift ANTLR runtime
You will find Swift runtime (framework project) in
## Build your Swift project with ANTLR runtime
```
antlr4/runtime/Swift
```
The following instructions are assuming Xcode as the IDE:
#### 4. Example playground
* __Add parser/lexer to project__. Make sure the parsers/lexers
generated in __step 2__ are added to the project. To do this, you can
drag the generated files from Finder to the Xcode IDE. Remember to
check __Copy items if needed__ to make sure the files are actually
moved into the project folder instead of symbolic links (see the
screenshot below). After moving you will be able to see your files in
the project navigator. But when you open one of the files, you will
see Xcode complaining the module "Antlr4" could not be found at the
import statement. This is expected, since we still need the ANTLR
Swift runtime for those missing symbols.
<img src=images/dragfile.png width="500">
* __Download ANTLR runtime__. Due to unstable ABI of Swift language,
there will not be a single "library" for the Swift ANTLR runtime for
now. To get Swift ANTLR runtime, clone the ANTLR repository. Open it
in finder. From the root directory of the repo, go to runtime/Swift
folder. You will see the Xcode project manifest file:
__Antlr4.xcodeproj__.
* __Import ANTLR Swift runtime into project__. Drag Antlr4.xcodeproj
into your project, after this is done, your Xcode project navigator
will be something like the screenshot below. In this case, your own
project is "Smalltalk", and you will be able to see the
Antlr4.xcodeproj shown as a contained project. The error message will
still be there, that's because we still need to tell Xcode how to find
the runtime.
<img src=images/xcodenav.png width="300">
* __Build ANTLR runtime__. By expanding the "Products" folder in the
inner project (Antlr4.xcodeproj), you will see two Antlr4.framework
files. ".framework" file is the swift version of ".jar", ".a" as in
JAVA, C/C++ Initially those two files should be red, that's because
they are not built. To build, click the "target selection" button
right next to your Xcode run button. And in the drop down select the
target you want to build. And you will see the two Antlr4.framework
files are for iOS and OSX, as shown below. After target selection,
press "CMD+B", and Xcode will build the framework for you. Then you
will see one of the frameworks become black.
<img src=images/targetselection.png width="500">
* __Add dependencies__. Simply adding ANTLR Swift runtime and build
the artifact is not enough. You still need to specify
dependencies. Click your own project (Smalltalk), and you will see
project setting page. Go to "Build Phase", and inside it make sure
your ANTLR Swift runtime framework is added to both "__Target
Dependencies__" and "__Link Binary With Libraries__" sections, as
shown below. After correctly added dependencies, the error message for
importing library will be gone.
<img src=images/xcodedep.png width="800">
## Example playground
The Swift runtime includes an Xcode playground to get started with.
In Xcode, open `antlr4/runtime/Swift/Antlr4.xcworkspace`. Select
"Antlr4 OSX > My Mac" as the build target, and build the project as normal.
The playground should then be active.

`runtime/Swift/Antlr4.xcworkspace` in Xcode. Select "Antlr4 OSX > My
Mac" as the build target, and build the project as normal. The
playground should then be active.
The playground includes a simple grammar called "Hello", and an example for
walking the parse tree. You should see in the playground output that it is
printing messages for each node in the parse tree as it walks.

how to execute the parse.
