# 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-ide/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 the Remix IDE (aka. Browser-Solidity).

## 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 do:
Remix-ide has been published as an npm module:
```bash
npm install remix-ide -g
remix-ide
```
Or if you want to clone the github repository (`wget` need to be installed first) :
```bash
git clone https://github.com/ethereum/remix-ide.git
git clone https://github.com/ethereum/remix.git # only if you plan to link remix and remix-ide repositories and develop on it.
cd remix # only if you plan to link remix and remix-ide repositories and develop on it.
npm install # only if you plan to link remix and remix-ide repositories and develop on it.
npm run bootstrap # only if you plan to link remix and remix-ide repositories and develop on it.
cd remix-ide
npm install
npm run setupremix # only if you plan to link remix and remix-ide repositories and develop on it.
npm start
```
## 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 `npm start` 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.
Most of the the time working with other modules (like debugger etc.) hosted in the [Remix repository](https://github.com/ethereum/remix) is not needed.
### 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`. 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
Register new unit test files in `test/index.js`.
The tests are written using [tape](https://www.npmjs.com/package/tape).
Run the unit tests via: `npm test`
For local headless browser tests run `npm run test-browser`
(requires Selenium to be installed - can be done with `npm run selenium-install`)
Running unit tests via `npm test` requires at least node v7.0.0
## Browser Testing
To run the Selenium tests via Nightwatch:
- Build Remix IDE and serve it: `npm run build && npm run 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_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_console
- npm run nightwatch_local_remixd # remixd needs to be run
**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
