Quick Start

Linting

To run golangci-lint:

Copy
golangci-lint run

It's an equivalent of:

Copy
golangci-lint run ./...

You can choose which directories or files to analyze:

Copy
golangci-lint run dir1 dir2/...
golangci-lint run file1.go

Directories are NOT analyzed recursively. To analyze them recursively append /... to their path. It's not possible to mix files and packages/directories, and files must come from the same package.

Golangci-lint can be used with zero configuration. By default, the following linters are enabled:

Copy
$ golangci-lint help linters
Enabled by default linters:
errcheck: Errcheck is a program for checking for unchecked errors in Go code. These unchecked errors can be critical bugs in some cases.
govet: Vet examines Go source code and reports suspicious constructs. It is roughly the same as 'go vet' and uses its passes. [auto-fix]
ineffassign: Detects when assignments to existing variables are not used. [fast]
staticcheck: It's the set of rules from staticcheck. [auto-fix]
unused: Checks Go code for unused constants, variables, functions and types.

Pass -E/--enable to enable linter and -D/--disable to disable:

Copy
golangci-lint run --default=none -E errcheck

More information about available linters can be found in the linters page.

Formatting

To format your code:

Copy
golangci-lint fmt

You can choose which directories or files to analyze:

Copy
golangci-lint fmt dir1 dir2/...
golangci-lint fmt file1.go
