## Compatibility
The OpenAPI Specification has undergone 3 revisions since initial creation in 2010.  The swagger-codegen project has the following compatibilities with the OpenAPI Specification:

Swagger Codegen Version    | Release Date | OpenAPI Spec compatibility | Notes
-------------------------- | ------------ | -------------------------- | -----
2.3.0 (upcoming minor release) | Apr/May 2017   | 1.0, 1.1, 1.2, 2.0   | Minor release with breaking changes
2.2.3 (upcoming patch release) | TBD   | 1.0, 1.1, 1.2, 2.0   | Patch release without breaking changes
[2.2.2](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.2.2) (**current stable**) | 2017-03-01   | 1.0, 1.1, 1.2, 2.0   | [tag v2.2.2](https://github.com/swagger-api/swagger-codegen/tree/v2.2.2)

### Prerequisites
If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 7 runtime at a minimum):

```
wget http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.2.2/swagger-codegen-cli-2.2.2.jar -O swagger-codegen-cli.jar

java -jar swagger-codegen-cli.jar help
```

On a mac, it's even easier with `brew`:
```
brew install swagger-codegen
```

To build from source, you need the following installed and available in your $PATH:

* [Java 7 or 8](http://java.oracle.com)

* [Apache maven 3.3.3 or greater](http://maven.apache.org/)

#### OS X Users
Don't forget to install Java 7 or 8. You probably have 1.6.

Export JAVA_HOME in order to use the supported Java version:
```
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
export PATH=${JAVA_HOME}/bin:$PATH
```

### Building

After cloning the project, you can build it from source with this command:
```
mvn clean package
```

### Homebrew

To install, run `brew install swagger-codegen`

Here is an example usage:
```
swagger-codegen generate -i http://petstore.swagger.io/v2/swagger.json -l ruby -o /tmp/test/
```

### Docker

#### Development in docker

You can use `run-in-docker.sh` to do all development. This script maps your local repository to `/gen`
in the docker container. It also maps `~/.m2/repository` to the appropriate container location.

To execute `mvn package`:

```
git clone https://github.com/swagger-api/swagger-codegen
cd swagger-codegen
./run-in-docker.sh mvn package
```

Build artifacts are now accessible in your working directory.

Once built, `run-in-docker.sh` will act as an executable for swagger-codegen-cli. To generate code, you'll need to output to a directory under `/gen` (e.g. `/gen/out`). For example:

```
./run-in-docker.sh help # Executes 'help' command for swagger-codegen-cli
./run-in-docker.sh langs # Executes 'langs' command for swagger-codegen-cli
./run-in-docker.sh /gen/bin/go-petstore.sh  # Builds the Go client
./run-in-docker.sh generate -i modules/swagger-codegen/src/test/resources/2_0/petstore.yaml \
    -l go -o /gen/out/go-petstore -DpackageName=petstore # generates go client, outputs locally to ./out/go-petstore
```

#### Run Docker in Vagrant
Prerequisite: install [Vagrant](https://www.vagrantup.com/downloads.html) and [VirtualBox](https://www.virtualbox.org/wiki/Downloads).
 ```
git clone http://github.com/swagger-api/swagger-codegen.git
cd swagger-codegen
vagrant up
vagrant ssh
cd /vagrant
./run-in-docker.sh mvn package
 ```

#### Public Pre-built Docker images

 - https://hub.docker.com/r/swaggerapi/swagger-generator/ (official web service)
 - https://hub.docker.com/r/swaggerapi/swagger-codegen-cli/ (official CLI)


##### Swagger Generator Docker Image

The Swagger Generator image can act as a self-hosted web application and API for generating code. This container can be  incorporated into a CI pipeline, and requires at least two HTTP requests and some docker orchestration to access generated code.

Example usage (note this assumes `jq` is installed for command line processing of JSON):

```
# Start container and save the container id
CID=$(docker run -d swaggerapi/swagger-generator)
# allow for startup
sleep 5
# Get the IP of the running container
GEN_IP=$(docker inspect --format '{{.NetworkSettings.IPAddress}}'  $CID)
# Execute an HTTP request and store the download link
RESULT=$(curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{
  "swaggerUrl": "http://petstore.swagger.io/v2/swagger.json"
}' 'http://localhost:8188/api/gen/clients/javascript' | jq '.link' | tr -d '"')
# Download the generated zip and redirect to a file
curl $RESULT > result.zip
# Shutdown the swagger generator image
docker stop $CID && docker rm $CID
```

In the example above, `result.zip` will contain the generated client.

##### Swagger Codegen CLI Docker Image

The Swagger Codegen image acts as a standalone executable. It can be used as an alternative to installing via homebrew, or for developers who are unable to install Java or upgrade the installed version.

To generate code with this image, you'll need to mount a local location as a volume.

Example:

```
docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli generate \
    -i http://petstore.swagger.io/v2/swagger.json \
    -l go \
    -o /local/out/go
```

The generated code will be located under `./out/go` in the current directory.

## Getting Started

To generate a PHP client for http://petstore.swagger.io/v2/swagger.json, please run the following
```sh
git clone https://github.com/swagger-api/swagger-codegen
cd swagger-codegen
mvn clean package
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
   -i http://petstore.swagger.io/v2/swagger.json \
   -l php \
   -o /var/tmp/php_api_client
```
(if you're on Windows, replace the last command with `java -jar modules\swagger-codegen-cli\target\swagger-codegen-cli.jar generate -i http://petstore.swagger.io/v2/swagger.json -l php -o c:\temp\php_api_client`)

You can also download the JAR (latest release) directly from [maven.org](http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.2.2/swagger-codegen-cli-2.2.2.jar)

To get a list of **general** options available, please run `java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar help generate`

To get a list of PHP specified options (which can be passed to the generator with a config file via the `-c` option), please run `java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar config-help -l php`

## Generators

### To generate a sample client library
You can build a client against the swagger sample [petstore](http://petstore.swagger.io) API as follows:

```
./bin/java-petstore.sh
```

(On Windows, run `.\bin\windows\java-petstore.bat` instead)

This will run the generator with this command:

```
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
  -i http://petstore.swagger.io/v2/swagger.json \
  -l java \
  -o samples/client/petstore/java
```

with a number of options. You can get the options with the `help generate` command (below only shows partal results):

```
NAME
        swagger-codegen-cli generate - Generate code with chosen lang

SYNOPSIS
        swagger-codegen-cli generate
                [(-a <authorization> | --auth <authorization>)]
                [--additional-properties <additional properties>]
                [--api-package <api package>] [--artifact-id <artifact id>]
                [--artifact-version <artifact version>]
                [(-c <configuration file> | --config <configuration file>)]
                [-D <system properties>] [--group-id <group id>]
                (-i <spec file> | --input-spec <spec file>)
                [--import-mappings <import mappings>]
                [--instantiation-types <instantiation types>]
                [--invoker-package <invoker package>]
                (-l <language> | --lang <language>)
                [--language-specific-primitives <language specific primitives>]
                [--library <library>] [--model-package <model package>]
                [(-o <output directory> | --output <output directory>)]
                [(-s | --skip-overwrite)]
                [(-t <template directory> | --template-dir <template directory>)]
                [--type-mappings <type mappings>] [(-v | --verbose)]

OPTIONS
        -a <authorization>, --auth <authorization>
            adds authorization headers when fetching the swagger definitions
            remotely. Pass in a URL-encoded string of name:header with a comma
            separating multiple values
	    
...... (results omitted)    

        -v, --verbose
            verbose mode

```

You can then compile and run the client, as well as unit tests against it:

```
cd samples/client/petstore/java
mvn package
```

Other languages have petstore samples, too:
```
./bin/android-petstore.sh
./bin/java-petstore.sh
./bin/objc-petstore.sh
```

### Generating libraries from your server
It's just as easy--just use the `-i` flag to point to either a server or file.

### Modifying the client library format
Don't like the default swagger client syntax?  Want a different language supported?  No problem!  Swagger codegen processes mustache templates with the [jmustache](https://github.com/samskivert/jmustache) engine.  You can modify our templates or make your own.

You can look at `modules/swagger-codegen/src/main/resources/${your-language}` for examples.  To make your own templates, create your own files and use the `-t` flag to specify your template folder.  It actually is that easy.

### Making your own codegen modules
If you're starting a project with a new language and don't see what you need, swagger-codegen can help you create a project to generate your own libraries:

```
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar meta \
  -o output/myLibrary -n myClientCodegen -p com.my.company.codegen
```

This will write, in the folder `output/myLibrary`, all the files you need to get started, including a README.md. Once modified and compiled, you can load your library with the codegen and generate clients with your own, custom-rolled logic.

You would then compile your library in the `output/myLibrary` folder with `mvn package` and execute the codegen like such:

```
java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar:modules/swagger-codegen-cli/target/swagger-codegen-cli.jar io.swagger.codegen.SwaggerCodegen
```
For Windows users, you will need to use `;` instead of `:` in the classpath, e.g.
```
java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar;modules/swagger-codegen-cli/target/swagger-codegen-cli.jar io.swagger.codegen.SwaggerCodegen
```

Note the `myClientCodegen` is an option now, and you can use the usual arguments for generating your library:

```
java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar:modules/swagger-codegen-cli/target/swagger-codegen-cli.jar \
  io.swagger.codegen.SwaggerCodegen generate -l myClientCodegen\
  -i http://petstore.swagger.io/v2/swagger.json \
  -o myClient
```

### Where is Javascript???
See our [javascript library](http://github.com/swagger-api/swagger-js)--it's completely dynamic and doesn't require
static code generation.
There is a third-party component called [swagger-js-codegen](https://github.com/wcandillon/swagger-js-codegen) that can generate angularjs or nodejs source code from a OpenAPI Specification.

:exclamation: On Dec 7th 2015, a Javascript API client generator has been added by @jfiala.

### Generating a client from local files
If you don't want to call your server, you can save the OpenAPI Spec files into a directory and pass an argument
to the code generator like this:

```
-i ./modules/swagger-codegen/src/test/resources/2_0/petstore.json
```

Great for creating libraries on your ci server, from the [Swagger Editor](http://editor.swagger.io)... or while coding on an airplane.

### Selective generation
You may not want to generate *all* models in your project.  Likewise you may want just one or two apis to be written.  If that's the case, you can use system properties to control the output:

The default is generate *everything* supported by the specific library.  Once you enable a feature, it will restrict the contents generated:

```
# generate only models
java -Dmodels {opts}

# generate only apis
java -Dapis {opts}

# generate only supporting files
java -DsupportingFiles

# generate models and supporting files
java -Dmodels -DsupportingFiles
```

To control the specific files being generated, you can pass a CSV list of what you want:
```
# generate the User and Pet models only
-Dmodels=User,Pet

# generate the User model and the supportingFile `StringUtil.java`:
-Dmodels=User -DsupportingFiles=StringUtil.java
```

To control generation of docs and tests for api and models, pass false to the option. For api, these options are  `-DapiTests=false` and `-DapiDocs=false`. For models, `-DmodelTests=false` and `-DmodelDocs=false`.
These options default to true and don't limit the generation of the feature options listed above (like `-Dapi`):

```
# generate only models (with tests and documentation)
java -Dmodels {opts}

# generate only models (with tests but no documentation)
java -Dmodels -DmodelDocs=false {opts}

# generate only User and Pet models (no tests and no documentation)
java -Dmodels=User,Pet -DmodelTests=false {opts}

# generate only apis (without tests)
java -Dapis -DapiTests=false {opts}

# generate only apis (modelTests option is ignored)
java -Dapis -DmodelTests=false {opts}
```

When using selective generation, _only_ the templates needed for the specific generation will be used.

### Ignore file format

Swagger codegen supports a `.swagger-codegen-ignore` file, similar to `.gitignore` or `.dockerignore` you're probably already familiar with.

The ignore file allows for better control over overwriting existing files than the `--skip-overwrite` flag. With the ignore file, you can specify individual files or directories can be ignored. This can be useful, for example if you only want a subset of the generated code.

Examples:

```
# Swagger Codegen Ignore
# Lines beginning with a # are comments

# This should match build.sh located anywhere.
build.sh

# Matches build.sh in the root
/build.sh

# Exclude all recursively
docs/**

# Explicitly allow files excluded by other rules
!docs/UserApi.md

# Recursively exclude directories named Api
# You can't negate files below this directory.
src/**/Api/

# When this file is nested under /Api (excluded above),
# this rule is ignored because parent directory is excluded by previous rule.
!src/**/PetApiTests.cs

# Exclude a single, nested file explicitly
src/IO.Swagger.Test/Model/AnimalFarmTests.cs
```

The `.swagger-codegen-ignore` file must exist in the root of the output directory.

### Customizing the generator

There are different aspects of customizing the code generator beyond just creating or modifying templates.  Each language has a supporting configuration file to handle different type mappings, etc:

```
$ ls -1 modules/swagger-codegen/src/main/java/io/swagger/codegen/languages/
AbstractJavaJAXRSServerCodegen.java
AbstractTypeScriptClientCodegen.java
... (results omitted)
TypeScriptAngularClientCodegen.java
TypeScriptNodeClientCodegen.java
```

Each of these files creates reasonable defaults so you can get running quickly.  But if you want to configure package names, prefixes, model folders, etc. you can use a json config file to pass the values.

```
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
  -i http://petstore.swagger.io/v2/swagger.json \
  -l java \
  -o samples/client/petstore/java \
  -c path/to/config.json
```
and `config.json` contains the following as an example:
```
{
  "apiPackage" : "petstore"
}
```

Supported config options can be different per language. Running `config-help -l {lang}` will show available options.  
**These options are applied via configuration file (e.g. config.json) or by passing them with `-D{optionName}={optionValue}`**. (If `-D{optionName}` does not work, please open a [ticket](https://github.com/swagger-api/swagger-codegen/issues/new) and we'll look into it)

```
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar config-help -l java
```

Output

```
CONFIG OPTIONS
	modelPackage
	    package for generated models

	apiPackage
	    package for generated api classes
...... (results omitted)
	library
	    library template (sub-template) to use:
	    jersey1 - HTTP client: Jersey client 1.18. JSON processing: Jackson 2.4.2
	    jersey2 - HTTP client: Jersey client 2.6
	    feign - HTTP client: Netflix Feign 8.1.1.  JSON processing: Jackson 2.6.3
	    okhttp-gson (default) - HTTP client: OkHttp 2.4.0. JSON processing: Gson 2.3.1
	    retrofit - HTTP client: OkHttp 2.4.0. JSON processing: Gson 2.3.1 (Retrofit 1.9.0)
        retrofit2 - HTTP client: OkHttp 2.5.0. JSON processing: Gson 2.4 (Retrofit 2.0.0-beta2)
```

Your config file for Java can look like

```json
{
  "groupId":"com.my.company",
  "artifactId":"MyClient",
  "artifactVersion":"1.2.0",
  "library":"feign"
}
```

For all the unspecified options default values will be used.

Another way to override default options is to extend the config class for the specific language.
To change, for example, the prefix for the Objective-C generated files, simply subclass the ObjcClientCodegen.java:

```java
package com.mycompany.swagger.codegen;

import io.swagger.codegen.languages.*;

public class MyObjcCodegen extends ObjcClientCodegen {
    static {
        PREFIX = "HELO";
    }
}
```

and specify the `classname` when running the generator:

```
-l com.mycompany.swagger.codegen.MyObjcCodegen
```

Your subclass will now be loaded and overrides the `PREFIX` value in the superclass.

### Bringing your own models

Sometimes you don't want a model generated.  In this case, you can simply specify an import mapping to tell
the codegen what _not_ to create.  When doing this, every location that references a specific model will
refer back to your classes.  Note, this may not apply to all languages...

To specify an import mapping, use the `--import-mappings` argument and specify the model-to-import logic as such:

```
--import-mappings Pet=my.models.MyPet
```

Or for multiple mappings:

```
Pet=my.models.MyPet,Order=my.models.MyOrder
```

### Validating your OpenAPI Spec

You have options.  The easiest is to use our [online validator](https://github.com/swagger-api/validator-badge) which not only will let you validate your spec, but with the debug flag, you can see what's wrong with your spec.  For example:

http://online.swagger.io/validator/debug?url=http://petstore.swagger.io/v2/swagger.json

### Generating dynamic html api documentation

To do so, just use the `-l dynamic-html` flag when reading a spec file.  This creates HTML documentation that is available as a single-page application with AJAX.  To view the documentation:

```
cd samples/dynamic-html/
npm install
node .
```

Which launches a node.js server so the AJAX calls have a place to go.


### Generating static html api documentation

To do so, just use the `-l html` flag when reading a spec file.  This creates a single, simple HTML file with embedded css so you can ship it as an email attachment, or load it from your filesystem:

```
cd samples/html/
open index.html
```


### To build a server stub

Please refer to https://github.com/swagger-api/swagger-codegen/wiki/Server-stub-generator-HOWTO for more information.

### To build the codegen library

This will create the swagger-codegen library from source.

```
mvn package
```

Note!  The templates are included in the library generated.  If you want to modify the templates, you'll need to either repackage the library OR specify a path to your scripts

## Workflow integration

You can use the [swagger-codegen-maven-plugin](modules/swagger-codegen-maven-plugin/README.md) for integrating with your workflow, and generating any codegen target.

## GitHub Integration

To push the auto-generated SDK to GitHub, we provide `git_push.sh` to streamline the process. For example:

 1) Create a new repository in GitHub (Ref: https://help.github.com/articles/creating-a-new-repository/)

 2) Generate the SDK
```
 java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
 -i modules/swagger-codegen/src/test/resources/2_0/petstore.json -l perl \
 --git-user-id "wing328" \
 --git-repo-id "petstore-perl" \
 --release-note "Github integration demo" \
 -o /var/tmp/perl/petstore
```
 3) Push the SDK to GitHub
```
cd /var/tmp/perl/petstore
/bin/sh ./git_push.sh
```

## Online generators

One can also generate API client or server using the online generators (https://generator.swagger.io)

For example, to generate Ruby API client, simply send the following HTTP request using curl:
```
curl -X POST -H "content-type:application/json" -d '{"swaggerUrl":"http://petstore.swagger.io/v2/swagger.json"}' https://generator.swagger.io/api/gen/clients/ruby
```
Then you will receieve a JSON response with the URL to download the zipped code.

To customize the SDK, you can `POST` to `https://generator.swagger.io/gen/clients/{language}` with the following HTTP body:
```
{
  "options": {},
  "swaggerUrl": "http://petstore.swagger.io/v2/swagger.json"
}
```
in which the `options` for a language can be obtained by submitting a `GET` request to `https://generator.swagger.io/api/gen/clients/{language}`:

For example, `curl https://generator.swagger.io/api/gen/clients/python` returns
```
{
  "packageName":{
    "opt":"packageName",
    "description":"python package name (convention: snake_case).",
    "type":"string",
    "default":"swagger_client"
  },
  "packageVersion":{
    "opt":"packageVersion",
    "description":"python package version.",
    "type":"string",
    "default":"1.0.0"
  },
  "sortParamsByRequiredFlag":{
    "opt":"sortParamsByRequiredFlag",
    "description":"Sort method arguments to place required parameters before optional parameters.",
    "type":"boolean",
    "default":"true"
  }
}
```
To set package name to `pet_store`, the HTTP body of the request is as follows:
```
{
  "options": {
    "packageName": "pet_store"
  },
  "swaggerUrl": "http://petstore.swagger.io/v2/swagger.json"
}
```
and here is the curl command:
```
curl -H "Content-type: application/json" -X POST -d '{"options": {"packageName": "pet_store"},"swaggerUrl": "http://petstore.swagger.io/v2/swagger.json"}' https://generator.swagger.io/api/gen/clients/python
```

Instead of using `swaggerUrl` with an URL to the OpenAPI/Swagger spec, one can include the spec in the JSON payload with `spec`, e.g.
```
{
  "options": {},
  "spec": {
    "swagger": "2.0",
    "info": {
      "version": "1.0.0",
      "title": "Test API"
    },
    ...
  }
}
```
