## Software Development Kit
For rapid development of modules and the OpenMRS Platform code check out the
awesome SDK at
https://wiki.openmrs.org/display/docs/OpenMRS+SDK
## Extending OpenMRS with Modules
OpenMRS has a modular architecture that allows developers to extend the OpenMRS core functionality by creating modules that can easily be added or removed to meet the needs of a specific implementation.
Before creating your own module go to the [OpenMRS Module Repository](https://addons.openmrs.org/) and see if there is already a module for your specific use case. If so deploy and try it and if a functionality is missing join the developers of the module to add a feature.
If you haven't found what you were looking for refer to the [Module - wiki](https://wiki.openmrs.org/display/docs/Modules) to learn how you can create a new module.

### Translation
We use
https://explore.transifex.com/openmrs/OpenMRS/
to manage our translations.
The `messages.properties` file in this repository is our single source of
truth. It contains key, value pairs for the English language which is the
default.
Transifex fetches updates to this file every night which can then be translated
by you and me on transifex website itself. At any time we can pull new translations from transifex
back into this repository. Other languages like for ex. Spanish will then be in
the `messages_es.properties` file.
If you would like to know how to help with translations see
https://openmrs.org/get-involved/translate-openmrs/

OpenMRS is a patient-based medical record system focusing on giving providers a free customizable electronic medical record system (EMR).
The mission of OpenMRS is to improve health care delivery in resource-constrained environments by coordinating a global community that creates a robust, scalable, user-driven, open source medical record system platform.

## Build
### Prerequisites
#### Java
OpenMRS is a Java application which is why you need to install a Java JDK.
If you want to build the master branch you will need a Java JDK of minimum version 8.
#### Maven
Install the build tool [Maven](https://maven.apache.org/).
You need to ensure that Maven uses the Java JDK needed for the branch you want to build.
To do so execute
```bash
mvn -version
```
which will tell you what version Maven is using. Refer to the [Maven docs](https://maven.apache.org/configure.html) if you need to configure Maven.
#### Git
Install the version control tool [git](https://git-scm.com/) and clone this repository with
```bash
git clone https://github.com/openmrs/openmrs-core.git
```
### Build Command
After you have taken care of the [Prerequisites](#prerequisites)
Execute the following
```bash
cd openmrs-core
mvn clean package
```
This will generate the OpenMRS application in `webapp/target/openmrs.war` which you will have to deploy into an application server like for example [tomcat](https://tomcat.apache.org/) or [jetty](http://www.eclipse.org/jetty/).
### Deploy
For development purposes you can simply deploy the `openmrs.war` into the application server jetty via
```bash
cd openmrs-core/webapp
mvn jetty:run
```
To run Jetty on a custom port, use the `jetty.http.port` property:
```bash
mvn -Djetty.http.port=8081 jetty:run
```
To run on Cargo, use the `cargo:run` command:
```bash
mvn cargo:run
```
To run Cargo on a custom port, use the `cargo.servlet.port` property:
```bash
mvn -Dcargo.servlet.port=8081 cargo:run
```
If all goes well (check the console output) you can access the OpenMRS application at `localhost:8080/openmrs`.
Refer to [Getting Started as a Developer - Maven](https://wiki.openmrs.org/display/docs/Maven) for some more information
on useful Maven commands and build options.
## Docker build
Docker builds are still work in progress. We appreciate any feedback and improvements to the process.
The only prerequisite needed is Docker.
In order to build a development version run:
```bash
docker compose build
```
It calls `mvn install` by default. If you would like to customize mvn build arguments you can do so by running:
```bash
docker compose build --build-arg MVN_ARGS='install -DskipTests'
```
It is also possible to use the built dev image to run jetty:
```bash
docker compose up
```
In order to build a production version run:
```bash
docker compose -f docker-compose.yml build
```
It first builds the dev image and then an image with Tomcat and openmrs.war.
It has no dev dependencies.
The production version can be run with:
```bash
docker compose -f docker-compose.yml up
```
If you want to debug, you need to run a development version and connect your debugger to port 8000, which is exposed by default.
Unfortunately, at this point any code changes require full restart and rebuild of the docker container. To speed up the process,
please use:
```bash
docker compose build --build-arg MVN_ARGS='install -DskipTests'
docker compose up
```
We are working towards providing support for Spring Boot auto-reload feature, which will be documented here once ready.
It is also possible to deploy an image built by our CI, which is published at
https://hub.docker.com/r/openmrs/openmrs-core
You can run any tag available with:
```bash
TAG=nightly docker compose -f docker-compose.yml up
```
It is also possible to run a development version of an image with:
```bash
TAG=dev docker compose up
```
All development versions contain dev suffix. The cache suffix is for use by our CI.
### Running with ElasticSearch
OpenMRS can run with ElasticSearch backend instead of the in-built Lucene index. You can run it with:
```bash
docker compose -f docker-compose.yml -f docker-compose.override.yml -f docker-compose.es.yml up
```
If you change backend, you need to rebuild the search index by going to Legacy UI -> Administration -> Search Index. Alternatively, you can rebuild the search index using the `searchindexupdate` REST endpoint.
