# Remix

Remix is a browser-based compiler and IDE that enables users to build **Ethereum contracts with Solidity language** and to debug transactions.

To try it out, visit [https://remix.ethereum.org](https://remix.ethereum.org).

https://github.com/ethereum/remix-project/releases also gives others ways to use Remix locally. Please check it out.

Remix consists of many modules and in this repository you will find Remix related apps, libs and plugins. (remix-ide, remix-analyzer, etc.).

## Offline Usage

The `gh-pages` branch has always the latest stable build of Remix. It also contains a ZIP file with the entire build. Download it to use offline.

Note: It contains the latest release of Solidity available at the time of the packaging. No other compiler versions are supported.


## INSTALLATION:

Install **npm** and **node.js** (see https://docs.npmjs.com/getting-started/installing-node), then
install [Nx CLI](https://nx.dev/react/cli/overview) globally to enable running **nx executable commands**.
```bash
npm install -g @nrwl/cli
```

clone the github repository (`wget` need to be installed first) :

```bash
git clone https://github.com/ethereum/remix-project.git

cd remix-project
npm install
nx build remix-ide --with-deps
nx serve
```

## Docker:

Prerequisites: 
* Docker (https://docs.docker.com/desktop/)
* Docker-compose (https://docs.docker.com/compose/install/)

### Run with docker

If you want to run latest changes that are merged into master branch then run:

```
docker pull remixproject/remix-ide:latest
docker run -p 8080:80 remixproject/remix-ide:latest
```

If you want to run latest remix-live release run.
```
docker pull remixproject/remix-ide:remix_live
docker run -p 8080:80 remixproject/remix-ide:remix_live
```

### Run with docker-compose:

To run locally without building you only need docker-compose.yaml file and you can run:

```
docker-compose pull
docker-compose up -d
```

Then go to http://localhost:8080 and you can use you Remix instance.

To fetch docker-compose file without cloning this repo run:
```
curl https://raw.githubusercontent.com/ethereum/remix-ide/master/docker-compose.yaml > docker-compose.yaml
```

## DEVELOPING:

Run `nx serve` and open `http://127.0.0.1:8080` in your browser.

Then open your `text editor` and start developing.
The browser will automatically refresh when files are saved.

### Troubleshooting building

Some things to consider if you have trouble building the package:

- Make sure that you have the correct version of `node`, `npm` and `nvm`. Also ensure you have [Nx CLI](https://nx.dev/react/cli/overview) installed globally. You can find the version that is tested on Travis CI by looking at the log in the [build results](https://travis-ci.org/ethereum/remix-ide).

Run:

```bash
node --version
npm --version
nvm --version
```

- In Debian based OS such as Ubuntu 14.04LTS you may need to run `apt-get install build-essential`. After installing `build-essential` run `npm rebuild`.

## Unit Testing

Run the unit tests via: `nx test <project-name>`
```bash
    nx test remix-analyzer
```

Running unit tests via `nx test` requires at least node v10.0.0

## Browser Testing

To run the Selenium tests via Nightwatch:

 - Build Remix IDE and serve it: `nx build remix-ide --with-deps && nx serve` # starts web server at localhost:8080
 - Make sure Selenium is installed `npm run selenium-install` # don't need to repeat
 - Run a selenium server `npm run selenium`
 - Run all the tests `npm run nightwatch_local_firefox` or `npm run nightwatch_local_chrome`
 - Or run a specific test case: 
 
		- npm run nightwatch_local_ballot

        - npm run nightwatch_local_usingWorker
		
		- npm run nightwatch_local_libraryDeployment
		
		- npm run nightwatch_local_solidityImport
		
		- npm run nightwatch_local_recorder
		
		- npm run nightwatch_local_transactionExecution
		
		- npm run nightwatch_local_staticAnalysis
		
		- npm run nightwatch_local_signingMessage

        - npm run nightwatch_local_specialFunctions

        - npm run nightwatch_local_solidityUnitTests

        - npm run nightwatch_local_remixd # remixd needs to be run

		- npm run nightwatch_local_terminal

        - npm run nightwatch_local_gist

        - npm run nightwatch_local_workspace

        - npm run nightwatch_local_defaultLayout

        - npm run nightwatch_local_pluginManager

        - npm run nightwatch_local_publishContract

        - npm run nightwatch_local_generalSettings

        - npm run nightwatch_local_fileExplorer

        - npm run nightwatch_local_debugger

        - npm run nightwatch_local_editor

        - npm run nightwatch_local_compiler

        - npm run nightwatch_local_txListener

        - npm run nightwatch_local_fileManager

        - npm run nightwatch_local_runAndDeploy
		
        
**NOTE:**

- **the `ballot` tests suite** requires to run `ganache-cli` locally.

- **the `remixd` tests suite** requires to run `remixd` locally.

- **the `gist` tests suite** requires specifying a github access token in **.env file**. 
```
    gist_token = <token>
```
**note that this token should have permission to create a gist.**


## Usage as a Chrome Extension

If you would like to use this as a Chrome extension, you must either build it first or pull from the `gh-pages` branch, both described above.
After that, follow these steps:

- Browse to `chrome://extensions/`
- Make sure 'Developer mode' has been checked
- Click 'Load unpacked extension...' to pop up a file-selection dialog
- Select your `remix-ide` folder
