**NOTE:** Golint is [deprecated and frozen](https://github.com/golang/go/issues/38968).
|
|
There's no drop-in replacement for it, but tools such as [Staticcheck](https://staticcheck.io/)
|
|
and `go vet` should be used instead.
|
|
|
|
Golint is a linter for Go source code.
|
|
|
|
[](https://pkg.go.dev/golang.org/x/lint)
|
|
[](https://travis-ci.org/golang/lint)
|
|
|
|
## Installation
|
|
|
|
Golint requires a
|
|
[supported release of Go](https://golang.org/doc/devel/release.html#policy).
|
|
|
|
go get -u golang.org/x/lint/golint
|
|
|
|
To find out where `golint` was installed you can run `go list -f {{.Target}} golang.org/x/lint/golint`. For `golint` to be used globally add that directory to the `$PATH` environment setting.
|
|
|
|
## Usage
|
|
|
|
Invoke `golint` with one or more filenames, directories, or packages named
|
|
by its import path. Golint uses the same
|
|
[import path syntax](https://golang.org/cmd/go/#hdr-Import_path_syntax) as
|
|
the `go` command and therefore
|
|
also supports relative import paths like `./...`. Additionally the `...`
|
|
wildcard can be used as suffix on relative and absolute file paths to recurse
|
|
into them.
|
|
|
|
The output of this tool is a list of suggestions in Vim quickfix format,
|
|
which is accepted by lots of different editors.
|
|
|
|
## Purpose
|
|
|
|
Golint differs from gofmt. Gofmt reformats Go source code, whereas
|
|
golint prints out style mistakes.
|
|
|
|
Golint differs from govet. Govet is concerned with correctness, whereas
|
|
golint is concerned with coding style. Golint is in use at Google, and it
|
|
seeks to match the accepted style of the open source Go project.
|
|
|
|
The suggestions made by golint are exactly that: suggestions.
|
|
Golint is not perfect, and has both false positives and false negatives.
|
|
Do not treat its output as a gold standard. We will not be adding pragmas
|
|
or other knobs to suppress specific warnings, so do not expect or require
|
|
code to be completely "lint-free".
|
|
In short, this tool is not, and will never be, trustworthy enough for its
|
|
suggestions to be enforced automatically, for example as part of a build process.
|
|
Golint makes suggestions for many of the mechanically checkable items listed in
|
|
[Effective Go](https://golang.org/doc/effective_go.html) and the
|
|
[CodeReviewComments wiki page](https://golang.org/wiki/CodeReviewComments).
|
|
|
|
## Scope
|
|
|
|
Golint is meant to carry out the stylistic conventions put forth in
|
|
[Effective Go](https://golang.org/doc/effective_go.html) and
|
|
[CodeReviewComments](https://golang.org/wiki/CodeReviewComments).
|
|
Changes that are not aligned with those documents will not be considered.

## Contributions
|
|
|
|
Contributions to this project are welcome provided they are [in scope](#scope),
|
|
though please send mail before starting work on anything major.
|
|
Contributors retain their copyright, so we need you to fill out
|
|
[a short form](https://developers.google.com/open-source/cla/individual)
|
|
before we can accept your contribution.
|
|
|
|
## Vim
|
|
|
|
Add this to your ~/.vimrc:
|
|
|
|
set rtp+=$GOPATH/src/golang.org/x/lint/misc/vim
|
|
|
|
If you have multiple entries in your GOPATH, replace `$GOPATH` with the right value.
|
|
|
|
Running `:Lint` will run golint on the current file and populate the quickfix list.
|
|
|
|
Optionally, add this to your `~/.vimrc` to automatically run `golint` on `:w`
|
|
|
|
autocmd BufWritePost,FileWritePost *.go execute 'Lint' | cwindow
|
|
|
|
|
|
## Emacs
|
|
|
|
Add this to your `.emacs` file:
|
|
|
|
(add-to-list 'load-path (concat (getenv "GOPATH") "/src/golang.org/x/lint/misc/emacs/"))
|
|
(require 'golint)
|
|
|
|
If you have multiple entries in your GOPATH, replace `$GOPATH` with the right value.
|
|
|
|
Running M-x golint will run golint on the current file.
|
