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

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

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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
