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 thesolidity
command. 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.
