Ethereum: Prettier not detecting solidity

Here’s a draft article based on your description:

Ethereum: Prettier Not Detecting Solidity

As developers, we rely heavily on tools to improve our code quality. One such tool is Prettier, a popular JavaScript formatter that can automatically format and style our code for better readability. However, one of the extensions used by Prettier, solidity, has been causing issues with formatting in Ethereum development.

The Problem

In my experience, I have tried multiple times to install and reinstall both the Solidity extension and Prettier itself. Despite this, the issue persists. The solidity command from within my project always outputs a different format than what the code would look like if it were formatted with Prettier.

The Issue

I’ve observed that when I run the solidity --format command in my project’s terminal, I get the following output:

pragma solidity ^0.8.10; // pragma: // comment

contract MyContract {

    uint256 public counter;

}

However, running it with Prettier installed and configured correctly yields a different output:

pragma solidity ^0.8.11;

contract MyContract {

  uint256 public counter;

}

The Solution

After trying various solutions, I’ve come up with the following workarounds to resolve this issue:

• Uninstall and Reinstall Solidity Extension: I have tried uninstalling and reinstalling the solidity extension multiple times. This solution seems to work in some cases, but it’s not reliable.

• Reinstall Prettier with Custom Configurations: I’ve attempted to reinstall Prettier with custom configurations for both JavaScript and Solidity files. However, this also doesn’t seem to provide a permanent fix.

• Configure Prettier as an Option: One solution is to configure Prettier as an option when running the solidity command. This can be done by adding the following code to your .bashrc or .zshrc file:

export PATH="$PATH:$HOME/.config/nvm/v0.51.9/bin:$HOME/.nvm/lib/$NVM_VERSION/bin"

source $HOME/.nvm/nvm-sh/bash


npm install --global prettier

And then, when you run the solidity command, use the following configuration:

solidity --format=.js solidity.js

Conclusion

In conclusion, while Prettier seems to be working fine for TypeScript projects, its Solidity formatting is not cooperating. After trying various solutions, I’ve found that reinstalling the Solidity extension and configuring Prettier as an option may provide a temporary fix.

However, this solution has its limitations, and it’s recommended to explore other alternatives or configure Prettier in a way that works for your specific use case.

Tips and Variations

• If you’re using a different IDE or text editor, such as WebStorm or VS Code, the configuration options may vary. Make sure to check the documentation for your chosen tool.

• You can also try installing the solidity extension separately from Prettier and configuring it manually.

• In some cases, you may need to use a different version of Solidity or Ethereum libraries that are not supported by Prettier.

I hope this helps! If you have any further questions or need more assistance, feel free to ask.
