Question 1

Is golangci-lint faster than running linters like go vet individually?

Accepted Answer

Yes, golangci-lint runs linters in parallel and uses caching, making it significantly faster for comprehensive checks. However, for very simple projects, individual linters might have less overhead.

Question 2

How to disable specific linters in golangci-lint?

Accepted Answer

You can disable linters by editing the .golangci.yml configuration file and setting the 'linters' section to exclude unwanted ones. This allows customization without removing the tool entirely.

Question 3

What's the best way to integrate golangci-lint with VS Code?

Accepted Answer

Install the golangci-lint extension from the VS Code marketplace and configure it to use your project's .golangci.yml file. It will run linting automatically as you code, providing real-time feedback.

Question 4

Can golangci-lint handle custom linters?

Accepted Answer

Yes, it supports custom linters through a plugin system, but this requires writing Go code and configuring it in YAML, which adds complexity and may not be well-documented for beginners.

Question 5

How does caching work to speed up linting?

Accepted Answer

golangci-lint caches results based on file hashes and configurations; if files haven't changed, it skips re-linting. This is especially useful in CI/CD pipelines where only modified code needs checking.

Question 6

golangci-lint vs staticcheck: which is better?

Accepted Answer

golangci-lint aggregates staticcheck and many other linters, offering broader coverage and parallelism. Use staticcheck alone if you need only its specific checks with simpler setup.
