Quick Start

To run golangci-lint execute:

Copy
golangci-lint run

It's an equivalent of executing:

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.
gosimple: Linter for Go source code that specializes in simplifying code. [auto-fix]
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 a set of rules from staticcheck. It's not the same thing as the staticcheck binary. The author of staticcheck doesn't support or approve the use of staticcheck as a library inside golangci-lint. [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 --disable-all -E errcheck

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