Ethereum: Prettier not detecting solidity

Here is a draft of an article based on your description:

Ethereum: Prettier Doesn’t Reveal Solidity

As developers, we rely heavily on tools to improve the quality of our code. 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, causes formatting issues in Ethereum development.

Problem

In my experience, I have tried installing and reinstalling both the Solidity extension and Prettier itself multiple times. However, the problem persists. The solidity command from my project always produces a different format than what the code would look like if formatted with Prettier.

Problem

I noticed that when I run the solidity --format command in the terminal of my project, I get the following output:

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

contract My contract {

uint256 public counter;

}

However, running it with Prettier installed and properly configured gives a different result:

pragma solidity ^0.8.11;

contract My contract {

uint256 public counter;

}

Decision

After trying various solutions, I came up with the following solutions to solve this problem:

  • 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 is not reliable.

  • Reinstall Prettier with custom configurations: I tried reinstalling Prettier with custom configurations for JavaScript and Solidity files. However, even this does not seem to provide a permanent solution.

  • Configure Prettier as an option

    : One solution is to configure Prettier as an option when running thesoliditycommand. This can be done by adding the following code to your.bashrcor.zshrcfile:


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 nicer

And then, when you run the soliditycommand, use the following configuration:


solidity --format=.js solidity.js

Conclusion

In conclusion, while Prettier seems to work well for TypeScript projects, its Solidity formatting does not cooperate. After trying various solutions, I found that reinstalling the Solidity extension and configuring Prettier as an option can provide a temporary fix.

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

Tips and Variations

  • If you are using a different IDE or text editor, such as WebStorm or VS Code, the configuration options may differ. Be 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 Prettier does not support.

Hope this helps! If you have any additional questions or need further assistance, feel free to ask.
