Customize Remix with URL Parameters¶

There are many ways to customize Remix IDE by using url parameters. Here are some options:

Activate or deactivate a list of plugins to be activated - and specify which plugin gains the “focus”. SEE MORE
Send commands to a plugin - once the plugin loads. SEE MORE
Load a GIST, a file via a url or a base64 encoded string into Remix’s Editor.
Specify the theme (Dark or Light). SEE MORE
Specify which panels should be minimized - useful when embedding Remix in your site. SEE MORE
Select the version of the Solidity compiler, enable/disable the optimizer, turn on auto compile or choose the language for the Solidity compiler. SEE MORE
Load verified contracts from Etherscan using contract address SEE MORE

Activating a list of plugins¶

The following example contains the url parameter activate followed by a comma separated list of plugins.

The last plugin in the list will gain the focus.

When you use the activate list, all other plugins that a user had loaded will be deactivated. This does not apply to the file explorer, the plugin manager, and the settings modules because these are never deactivated.

https://remix.ethereum.org/?#activate=solidity,solidityUnitTesting,defiexplorer

Note: a plugin is called by its name as specified in its profile. There are 3 types of plugins:

Native Mandatory Plugins that are always loaded (so you don’t need to activate them using the url parameter activate). These include: fileManager, settings, manager (the plugin manager), and udapp (deploy & run).
Native Optional Plugins that are loaded on demand: debugger, hardhat-provider, solidity, solidityStaticAnalysis, solidityUnitTesting, and vyper
External Plugins to get these plugins’ names, please go to https://github.com/ethereum/remix-plugins-directory/tree/master/plugins.

Deactiving a list of plugins¶

https://remix.ethereum.org/?#deactivate=debugger

Minimizing Remix panels¶

The following URL will close everything except the main panel & the icon panel (the side and terminal are minimized).

https://remix.ethereum.org/?#embed=true

To minimize just the side panel, use this URL:

https://remix.ethereum.org/?#minimizesidepanel=true

To minimize just the terminal, use this URL:

https://remix.ethereum.org/?#minimizeterminal=true

Specifying a theme¶

To link to Remix with a theme specified use this url:

 **https://remix.ethereum.org/?#theme=Dark**

A URL example combining multiple parameters¶

To link to Remix with the a list of plugins activated and with:

the Learneth gaining the side panel’s focus (because it is the last in the list)
the Light theme loaded
the terminal minimized
optimize off

use this url:

 https://remix.ethereum.org/?#activate=solidity,solidityUnitTesting,LearnEth&theme=Light&minimizeterminal=true&optimize=false&evmVersion=null&version=soljson-v0.6.6+commit.6c089d02.js

Pass commands to a plugin’s API via a url param¶

The URL parameter to issue a command is call. Following the call is a // (double slash) separated list of arguments.

call=plugin_name//function//parameter1//paremeter2

An example using call¶

The URL below uses activate & call. It activates a number of plugins and calls the File Explorers to tell it to load one of the default Remix files:

https://remix.ethereum.org/?#activate=defiexplorer,solidity&call=fileManager//open//contracts/3_Ballot.sol

Load a specific tutorial in the LearnEth plugin:¶

https://remix.ethereum.org/?#activate=solidityUnitTesting,solidity,LearnEth&call=LearnEth//startTutorial//ethereum/remix-workshops//master//proxycontract

Make calls to a number of different plugins’ APIs¶

Use the calls parameter to call a series of plugins. Use /// to separate the calls.

For example, this command, after activating a list of plugins, calls the LearnEth plugin’s API and then calls the File Explorer’s API.

https://remix.ethereum.org/?#activate=solidityUnitTesting,solidity,LearnEth&calls=LearnEth//startTutorial//ethereum/remix-workshops//master//proxycontract///fileManager//open//contracts/3_Ballot.sol

Load a file via a URL into the Editor¶

The url parameter takes a URL, loads it into the Editor and saves it into the code-sample workspace of the File Explorer:

https://remix.ethereum.org/#url=https://github.com/ethereum/remix-project/blob/master/apps/remix-ide/contracts/app/solidity/mode.sol

Load an encoded base64 string into a .sol file in the Editor¶

The code parameter takes an encoded base64 string and loads it into the Editor as a .sol file and saves to the code-sample workspace of the File Explorer:

https://remix.ethereum.org/?#code=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

Load contracts from Etherscan via address¶

The address parameter takes an address, loads all the verified contracts found for the address on different Ethereum networks and saves them into the etherscan-code-sample workspace of the File Explorer:

https://remix.ethereum.org/#address=0xdac17f958d2ee523a2206206994597c13d831ec7

Load a Solidity contract from Github¶

With a github url of a Solidity contract like this one:

https://github.com/ethereum/remix-project/blob/master/apps/remix-ide/contracts/app/solidity/mode.sol

Then delete the github part and type in remix.ethereum.org in its place, like this:

https://remix.ethereum.org/ethereum/remix-project/blob/master/apps/remix-ide/contracts/app/solidity/mode.sol

Remix will fetch the Solidity file and open it up in the File Explorer in a Workspace named
code-sample.

Load a GIST¶

The URL parameter here is gist.

https://remix.ethereum.org/?gist=0fe90e825327ef313c88aedfe66ec142

Load a GIST and have it be visible in the Editor:¶

Using both gist & call

https://remix.ethereum.org/?#activate=solidity,debugger&gist=0fe90e825327ef313c88aedfe66ec142&call=fileManager//open//browser/gists/0fe90e825327ef313c88aedfe66ec142/gridMix4.sol

Load a GIST, have it be visible in the Editor & load a list of plugins:¶

https://remix.ethereum.org/?#activate=solidity,LearnEth&gist=0fe90e825327ef313c88aedfe66ec142&call=fileManager//open//browser/gists/0fe90e825327ef313c88aedfe66ec142/gridMix4.sol 

Load a specific version of the Solidity compiler:¶

https://remix.ethereum.org/?#version=soljson-v0.6.6+commit.6c089d02

Note: you need to specify both the Solidity version and the commit.

Load a custom Solidity compiler:¶

https://remix.ethereum.org/#version=https://solidity-blog.s3.eu-central-1.amazonaws.com/data/08preview/soljson.js

Turn on autoCompile:¶

https://remix.ethereum.org/#autoCompile=true

Select the language for the Solidity Compiler¶

Choose YUL or Solidity with the language parameter.

https://remix.ethereum.org/#language=Yul
