revive

Fast, configurable, extensible, flexible, and beautiful linter for Go. Drop-in replacement of golint. Revive provides a framework for development of custom rules, and lets you define a strict preset for enhancing your development & code review processes.

Logo by Georgi Serev

Here's how revive is different from golint:

Allows to enable or disable rules using a configuration file.
Allows to configure the linting rules with a TOML file.
2x faster running the same rules as golint.
Provides functionality for disabling a specific rule or the entire linter for a file or a range of lines.
- golint allows this only for generated files.
Optional type checking. Most rules in golint do not require type checking. If you disable them in the config file, revive will run over 6x faster than golint.
Provides multiple formatters which let us customize the output.
Allows to customize the return code for the entire linter or based on the failure of only some rules.
Everyone can extend it easily with custom rules or formatters.
Revive provides more rules compared to golint.

revive

Installation

go install github.com/mgechev/revive@latest

or get a released executable from the Releases page.

You can install the main branch (including the last commit) with:

go install github.com/mgechev/revive@master

Usage

Since the default behavior of revive is compatible with golint, without providing any additional flags, the only difference you'd notice is faster execution.

revive supports a -config flag whose value should correspond to a TOML file describing which rules to use for revive's linting. If not provided, revive will try to use a global config file (assumed to be located at $HOME/revive.toml). Otherwise, if no configuration TOML file is found then revive uses a built-in set of default linting rules.

Docker

A volume needs to be mounted to share the current repository with the container.
Please refer to the bind mounts Docker documentation

docker run -v "$(pwd)":/var/<repository> ghcr.io/mgechev/revive:v1.1.2-next -config /var/<repository>/revive.toml -formatter stylish ./var/kidle/...

-v is for the volume
ghcr.io/mgechev/revive:v1.1.2-next is the image name and its version corresponding to revive command
The provided flags are the same as the binary usage.

Linter aggregators

golangci-lint

To enable revive in golangci-lint you need to add revive to the list of enabled linters:

# golangci-lint configuration file
linters:
   enable:
     - revive

Then revive can be configured by adding an entry to the linters-settings section of the configuration, for example:

# golangci-lint configuration file
linters-settings:
  revive:
    ignore-generated-header: true
    severity: warning
    rules:
      - name: atomic
      - name: line-length-limit
        severity: error
        arguments: [80]
      - name: unhandled-error
        arguments : ["fmt.Printf", "myFunction"]

The above configuration enables three rules of revive: atomic, line-length-limit and unhandled-error and pass some arguments to the last two. The Configuration section of this document provides details on how to configure revive. Note that while revive configuration is in TOML, that of golangci-lint is in YAML.

Please notice that if no particular configuration is provided, revive will behave as go-lint does, i.e. all go-lint rules are enabled (the Available Rules table details what are the go-lint rules). When a configuration is provided, only rules in the configuration are enabled.

Command Line Flags

revive accepts the following command line parameters:

-config [PATH] - path to config file in TOML format, defaults to $HOME/revive.toml if present.
-exclude [PATTERN] - pattern for files/directories/packages to be excluded for linting. You can specify the files you want to exclude for linting either as package name (i.e. github.com/mgechev/revive), list them as individual files (i.e. file.go), directories (i.e. ./foo/...), or any combination of the three.
-formatter [NAME] - formatter to be used for the output. The currently available formatters are:
- default - will output the failures the same way that golint does.
- json - outputs the failures in JSON format.
- ndjson - outputs the failures as stream in newline delimited JSON (NDJSON) format.
- friendly - outputs the failures when found. Shows summary of all the failures.
- stylish - formats the failures in a table. Keep in mind that it doesn't stream the output so it might be perceived as slower compared to others.
- checkstyle - outputs the failures in XML format compatible with that of Java's Checkstyle.
-max_open_files - maximum number of open files at the same time. Defaults to unlimited.
-set_exit_status - set exit status to 1 if any issues are found, overwrites errorCode and warningCode in config.
-version - get revive version.

Sample Invocations

revive -config revive.toml -exclude file1.go -exclude file2.go -formatter friendly github.com/mgechev/revive package/...

The command above will use the configuration from revive.toml
revive will ignore file1.go and file2.go
The output will be formatted with the friendly formatter
The linter will analyze github.com/mgechev/revive and the files in package

Comment Directives

Using comments, you can disable the linter for the entire file or only range of lines:

//revive:disable

func Public() {}
//revive:enable

The snippet above, will disable revive between the revive:disable and revive:enable comments. If you skip revive:enable, the linter will be disabled for the rest of the file.

With revive:disable-next-line and revive:disable-line you can disable revive on a particular code line.

You can do the same on a rule level. In case you want to disable only a particular rule, you can use:

//revive:disable:unexported-return
func Public() private {
  return private
}
//revive:enable:unexported-return

This way, revive will not warn you for that you're returning an object of an unexported type, from an exported function.

You can document why you disable the linter by adding a trailing text in the directive, for example

//revive:disable Until the code is stable

//revive:disable:cyclomatic High complexity score but easy to understand

You can also configure revive to enforce documenting linter disabling directives by adding

[directive.specify-disable-reason]

in the configuration. You can set the severity (defaults to warning) of the violation of this directive

[directive.specify-disable-reason]
    severity = "error"

Configuration

revive can be configured with a TOML file. Here's a sample configuration with explanation for the individual properties:

# When set to false, ignores files with "GENERATED" header, similar to golint
ignoreGeneratedHeader = true

# Sets the default severity to "warning"
severity = "warning"

# Sets the default failure confidence. This means that linting errors
# with less than 0.8 confidence will be ignored.
confidence = 0.8

# Sets the error code for failures with severity "error"
errorCode = 0

# Sets the error code for failures with severity "warning"
warningCode = 0

# Configuration of the `cyclomatic` rule. Here we specify that
# the rule should fail if it detects code with higher complexity than 10.
[rule.cyclomatic]
  arguments = [10]

# Sets the severity of the `package-comments` rule to "error".
[rule.package-comments]
  severity = "error"

By default revive will enable only the linting rules that are named in the configuration file. For example, the previous configuration file makes revive to enable only cyclomatic and package-comments linting rules.

To enable all available rules you need to add:

enableAllRules = true

This will enable all available rules no matter of what rules are named in the configuration file.

To disable a rule, you simply mark it as disabled in the configuration. For example:

[rule.line-length-limit]
    Disabled = true

When enabling all rules you still need/can provide specific configurations for rules. The following files is an example configuration were all rules are enabled, with exception to those that are explicitly disabled, and some rules are configured with particular arguments:

severity = "warning"
confidence = 0.8
errorCode = 0
warningCode = 0

# Enable all available rules
enableAllRules = true

# Disabled rules
[rule.blank-imports]
    Disabled = true
[rule.file-header]
    Disabled = true
[rule.max-public-structs]
    Disabled = true
[rule.line-length-limit]
    Disabled = true
[rule.function-length]
    Disabled = true
[rule.banned-characters]
    Disabled = true

# Rule tuning
[rule.argument-limit]
    Arguments = [5]
[rule.cyclomatic]
    Arguments = [10]
[rule.cognitive-complexity]
    Arguments = [7]
[rule.function-result-limit]
    Arguments = [3]
[rule.error-strings]
    Arguments = ["mypackage.Error"]

Default Configuration

The default configuration of revive can be found at defaults.toml. This will enable all rules available in golint and use their default configuration (i.e. the way they are hardcoded in golint).

revive -config defaults.toml github.com/mgechev/revive

This will use the configuration file defaults.toml, the default formatter, and will run linting over the github.com/mgechev/revive package.

Custom Configuration

revive -config config.toml -formatter friendly github.com/mgechev/revive

This will use config.toml, the friendly formatter, and will run linting over the github.com/mgechev/revive package.

Recommended Configuration

The following snippet contains the recommended revive configuration that you can use in your project:

ignoreGeneratedHeader = false
severity = "warning"
confidence = 0.8
errorCode = 0
warningCode = 0

Configurable rules

Here you can find how you can configure some existing rules:

`var-naming`

This rule accepts two slices of strings, a whitelist and a blacklist of initialisms. By default, the rule behaves exactly as the alternative in golint but optionally, you can relax it (see golint/lint/issues/89)

[rule.var-naming]
  arguments = [["ID"], ["VM"]]

This way, revive will not warn for identifier called customId but will warn that customVm should be called customVM.

Available Formatters

This section lists all the available formatters and provides a screenshot for each one.

Friendly

Stylish

Default

The default formatter produces the same output as golint.

Plain

The plain formatter produces the same output as the default formatter and appends URL to the rule description.

Unix

The unix formatter produces the same output as the default formatter but surrounds the rules in [].

SARIF

The sarif formatter produces outputs in SARIF, for Static Analysis Results Interchange Format, a standard JSON-based format for the output of static analysis tools defined and promoted by OASIS.

Current supported version of the standard is SARIF-v2.1.0.

Extensibility

The tool can be extended with custom rules or formatters. This section contains additional information on how to implement such.

To extend the linter with a custom rule you can push it to this repository or use revive as a library (see below)

To add a custom formatter you'll have to push it to this repository or fork it. This is due to the limited -buildmode=plugin support which works only on Linux (with known issues).

Writing a Custom Rule

Each rule needs to implement the lint.Rule interface:

type Rule interface {
	Name() string
	Apply(*File, Arguments) []Failure
}

The Arguments type is an alias of the type []interface{}. The arguments of the rule are passed from the configuration file.

Example

Let's suppose we have developed a rule called BanStructNameRule which disallow us to name a structure with given identifier. We can set the banned identifier by using the TOML configuration file:

[rule.ban-struct-name]
  arguments = ["Foo"]

With the snippet above we:

Enable the rule with name ban-struct-name. The Name() method of our rule should return a string which matches ban-struct-name.
Configure the rule with the argument Foo. The list of arguments will be passed to Apply(*File, Arguments) together with the target file we're linting currently.

A sample rule implementation can be found here.

Using `revive` as a library

If a rule is specific to your use case (i.e. it is not a good candidate to be added to revive's rule set) you can add it to your own linter using revive as linting engine.

The following code shows how to use revive in your own application. In the example only one rule is added (myRule), of course, you can add as many as you need to. Your rules can be configured programmatically or with the standard revive configuration file. The full rule set of revive is also actionable by your application.

package main

import (
	"github.com/mgechev/revive/cli"
	"github.com/mgechev/revive/lint"
	"github.com/mgechev/revive/revivelib"
)

func main() {
	cli.RunRevive(revivelib.NewExtraRule(&myRule{}, lint.RuleConfig{}))
}

type myRule struct{}

func (f myRule) Name() string {
	return "myRule"
}

func (f myRule) Apply(*lint.File, lint.Arguments) []lint.Failure { ... }

You can still go further and use revive without its cli, as part of your library, or your own cli:

package mylib

import (
	"github.com/mgechev/revive/cli"
	"github.com/mgechev/revive/revivelib"
	"github.com/mgechev/revive/lint"
)

// Error checking removed for clarity
func LintMyFile(file string) {
	conf, _:= config.GetConfig("../defaults.toml")

	revive, _ := revivelib.New(
		conf,  // Configuration file
		true,  // Set exit status
		2048,  // Max open files

		// Then add as many extra rules as you need
		revivelib.NewExtraRule(&myRule{}, lint.RuleConfig{}),
	)

	failuresChan, err := revive.Lint(
 		revivelib.Include(file),
 		revivelib.Exclude("./fixtures"),
 		// You can use as many revivelib.Include or revivelib.Exclude as required
 	)
  	if err != nil {
  	 	panic("Shouldn't have failed: " + err.Error)
  	}

  	// Now let's return the formatted errors
	failures, exitCode, _ := revive.Format("stylish", failuresChan)

  	// failures is the string with all formatted lint error messages
  	// exit code is 0 if no errors, 1 if errors (unless config options change it)
  	// ... do something with them
}

type myRule struct{}

func (f myRule) Name() string {
	return "myRule"
}

func (f myRule) Apply(*lint.File, lint.Arguments) []lint.Failure { ... }

Custom Formatter

Each formatter needs to implement the following interface:

type Formatter interface {
	Format(<-chan Failure, Config) (string, error)
	Name() string
}

The Format method accepts a channel of Failure instances and the configuration of the enabled rules. The Name() method should return a string different from the names of the already existing rules. This string is used when specifying the formatter when invoking the revive CLI tool.

For a sample formatter, take a look at this file.

Speed Comparison

Compared to golint, revive performs better because it lints the files for each individual rule into a separate goroutine. Here's a basic performance benchmark on MacBook Pro Early 2013 run on kubernetes:

golint

time golint kubernetes/... > /dev/null

real    0m54.837s
user    0m57.844s
sys     0m9.146s

revive

# no type checking
time revive -config untyped.toml kubernetes/... > /dev/null

real    0m8.471s
user    0m40.721s
sys     0m3.262s

Keep in mind that if you use rules which require type checking, the performance may drop to 2x faster than golint:

# type checking enabled
time revive kubernetes/... > /dev/null

real    0m26.211s
user    2m6.708s
sys     0m17.192s

Currently, type checking is enabled by default. If you want to run the linter without type checking, remove all typed rules from the configuration file.

Overriding colorization detection

By default, revive determines whether or not to colorize its output based on whether it's connected to a TTY or not. This works for most use cases, but may not behave as expected if you use revive in a pipeline of commands, where STDOUT is being piped to another command.

To force colorization, add REVIVE_FORCE_COLOR=1 to the environment you're running in. For example:

REVIVE_FORCE_COLOR=1 revive -formatter friendly ./... | tee revive.log
