The swagger-codegen project has the following compatibilities with the OpenAPI Specification: Swagger Codegen Version | Release Date | OpenAPI Spec compatibility | Notes -------------------------- | ------------ | -------------------------- | ----- 3.0.0 (upcoming major release) [SNAPSHOT](https://oss.sonatype.org/content/repositories/snapshots/io/swagger/swagger-codegen-cli/3.0.0-SNAPSHOT/)| TBD | 1.0, 1.1, 1.2, 2.0, 3.0 | Major release with breaking changes 2.4.0 (current master, upcoming minor release) [SNAPSHOT](https://oss.sonatype.org/content/repositories/snapshots/io/swagger/swagger-codegen-cli/2.4.0-SNAPSHOT/)| TBD | 1.0, 1.1, 1.2, 2.0 | Minor release with breaking changes [2.3.1](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.3.1) (**current stable**) | 2018-01-17 | 1.0, 1.1, 1.2, 2.0 | [tag v2.3.1](https://github.com/swagger-api/swagger-codegen/tree/v2.3.1) [2.3.0](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.3.0) | 2017-12-21 | 1.0, 1.1, 1.2, 2.0 | [tag v2.3.0](https://github.com/swagger-api/swagger-codegen/tree/v2.3.0) [2.2.3](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.2.3) | 2017-07-15 | 1.0, 1.1, 1.2, 2.0 | [tag v2.2.3](https://github.com/swagger-api/swagger-codegen/tree/v2.2.3) [2.2.2](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.2.2) | 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) [2.2.1](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.2.1) | 2016-08-07 | 1.0, 1.1, 1.2, 2.0 | [tag v2.2.1](https://github.com/swagger-api/swagger-codegen/tree/v2.2.1) [2.1.6](https://github.com/swagger-api/swagger-codegen/releases/tag/v2.1.6) | 2016-04-06 | 1.0, 1.1, 1.2, 2.0 | [tag v2.1.6](https://github.com/swagger-api/swagger-codegen/tree/v2.1.6) 2.0.17 | 2014-08-22 | 1.1, 1.2 | [tag v2.0.17](https://github.com/swagger-api/swagger-codegen/tree/2.0.17) 1.0.4 | 2012-04-12 | 1.0, 1.1 | [tag v1.0.4](https://github.com/swagger-api/swagger-codegen/tree/swagger-codegen_2.9.1-1.1) ### Prerequisites If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 7 runtime at a minimum): ```sh wget http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar -O swagger-codegen-cli.jar java -jar swagger-codegen-cli.jar help ``` For Windows users, you will need to install [wget](http://gnuwin32.sourceforge.net/packages/wget.htm) or you can use Invoke-WebRequest in PowerShell (3.0+), e.g. `Invoke-WebRequest -OutFile swagger-codegen-cli.jar http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar` On a mac, it's even easier with `brew`: ```sh brew install swagger-codegen ``` To build from source, you need the following installed and available in your `$PATH:` * [Java 7 or 8](http://java.oracle.com) * [Apache maven 3.3.3 or greater](http://maven.apache.org/) #### OS X Users Don't forget to install Java 7 or 8. You probably have 1.6. Export `JAVA_HOME` in order to use the supported Java version: ```sh export JAVA_HOME=`/usr/libexec/java_home -v 1.8` export PATH=${JAVA_HOME}/bin:$PATH ``` ### Building After cloning the project, you can build it from source with this command: ```sh mvn clean package ``` If you don't have maven installed, you may directly use the included [maven wrapper](https://github.com/takari/maven-wrapper), and build with the command: ```sh ./mvnw clean package ``` ### Homebrew To install, run `brew install swagger-codegen` Here is an example usage: ```sh 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`: ```sh 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: ```sh ./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). ```sh 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): ```sh # 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: ```sh 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/2.3.1/swagger-codegen-cli-2.3.1.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: ```sh ./bin/java-petstore.sh ``` (On Windows, run `.\bin\windows\java-petstore.bat` instead) This will run the generator with this command: ```sh 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 partial results): ``` NAME swagger-codegen-cli generate - Generate code with chosen lang SYNOPSIS swagger-codegen-cli generate [(-a | --auth )] [--additional-properties ...] [--api-package ] [--artifact-id ] [--artifact-version ] [(-c | --config )] [-D ...] [--git-repo-id ] [--git-user-id ] [--group-id ] [--http-user-agent ] (-i | --input-spec ) [--ignore-file-override ] [--import-mappings ...] [--instantiation-types ...] [--invoker-package ] (-l | --lang ) [--language-specific-primitives ...] [--library ] [--model-name-prefix ] [--model-name-suffix ] [--model-package ] [(-o | --output )] [--release-note ] [--remove-operation-id-prefix] [--reserved-words-mappings ...] [(-s | --skip-overwrite)] [(-t
