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`.

## 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.
### Bazel
If you want to use revive with Bazel, take a look at the [rules](https://github.com/atlassian/bazel-tools/tree/master/gorevive) that Atlassian maintains.

(free for open-source projects)
### Installation
```bash
go get -u github.com/mgechev/revive
```
### Command Line Flags
`revive` accepts three 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](https://checkstyle.org/).
### Sample Invocations
```shell
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:
```go
//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:
```go
//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
```go
//revive:disable Until the code is stable
```
```go
//revive:disable:cyclomatic High complexity score but easy to understand
```
You can also configure `revive` to enforce documenting linter disabling directives by adding
```toml
[directive.specify-disable-reason]
```
in the configuration. You can set the severity (defaults to _warning_) of the violation of this directive
```toml
[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:
```toml
# 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"
```
### 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`).
```shell
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
```shell
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:
```toml
ignoreGeneratedHeader = false
severity = "warning"
confidence = 0.8
errorCode = 0
warningCode = 0

## Configurable rules
Here you can find how you can configure some of the 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](https://github.com/golang/lint/issues/89))
```toml
[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
![Friendly formatter](/assets/formatter-friendly.png)
### Stylish
![Stylish formatter](/assets/formatter-stylish.png)
### Default
The default formatter produces the same output as `golint`.
![Default formatter](/assets/formatter-default.png)
### Plain
The plain formatter produces the same output as the default formatter and appends URL to the rule description.
![Plain formatter](/assets/formatter-plain.png)
### Unix
The unix formatter produces the same output as the default formatter but surrounds the rules in `[]`.
![Unix formatter](/assets/formatter-unix.png)
## 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 or a 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)](https://golang.org/pkg/plugin/).
### Custom Rule
Each rule needs to implement the `lint.Rule` interface:
```go
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:
```toml
[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](/rule/argument-limit.go).
### Custom Formatter
Each formatter needs to implement the following interface:
```go
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](/formatter/json.go).
## 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
```shell
time golint kubernetes/... > /dev/null
real 0m54.837s
user 0m57.844s
sys 0m9.146s
```
### revive
```shell
# 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`:
```shell
# 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:
```shell
REVIVE_FORCE_COLOR=1 revive -formatter friendly ./... | tee revive.log
```
