## Directory and file conventions
## Directory and File Conventions
- Avoid generic utility packages. Instead of naming a package "util", choose a name that clearly describes its purpose. For instance, functions related to waiting operations are contained within the `wait` package, which includes methods like `Poll`, fully named as `wait.Poll`.
- All filenames, script files, configuration files, and directories should be in lowercase and use dashes (`-`) as separators.
- For Go language files, filenames should be in lowercase and use underscores (`_`).
- Package names should match their directory names to ensure consistency. For example, within the `openim-api` directory, the Go file should be named `openim-api.go`, following the convention of using dashes for directory names and aligning package names with directory names.
- Avoid general utility packages. Packages called "util" are suspect. Instead, derive a name that describes your desired function. For example, the utility functions dealing with waiting for operations are in the `wait` package and include functionality like `Poll`. The full name is `wait.Poll`.
- All filenames should be lowercase.
- All source files and directories should use underscores, not dashes.
- Package directories should generally avoid using separators as much as possible. When package names are multiple words, they usually should be in nested subdirectories.

golangci lint can select the types of tools, refer to the official documentation: [https://golangci-lint.run/usage/linters/](https://golangci-lint.run/usage/linters/)
The types of comments we currently use include: [https://github.com/openimsdk/open-im-server/blob/main/.golangci.yml](https://github.com/openimsdk/open-im-server/blob/main/.golangci.yml) the `linters.enable` field in the file.
e.g:
```yaml
linters:
# please, do not use `enable-all`: it's deprecated and will be removed soon.
# inverted configuration with `enable-all` and `disable` is not scalable during updates of golangci-lint
# enable-all: true
disable-all: true
enable:
- typecheck # Basic type checking
- gofmt # Format check
- govet # Go's standard linting tool
- gosimple # Suggestions for simplifying code
- misspell # Spelling mistakes
- staticcheck # Static analysis
- unused # Checks for unused code
- goimports # Checks if imports are correctly sorted and formatted
- godot # Checks for comment punctuation
- bodyclose # Ensures HTTP response body is closed
- errcheck # Checks for missed error returns

Add that Chinese comments are not allowed in go code, please write a complete golangci lint specification on the basis of the above.
### 10.1 Configuration Document
This configuration document is designed to configure the operational parameters of OpenIM (a hypothetical or specific code analysis tool), customize output formats, and provide detailed settings for specific code checkers (linters). Below is a summary of the document drafted based on the provided configuration information.
#### 10.1 Runtime Options
- **Concurrency** (`concurrency`): Default to use the available CPU count, can be manually set to 4 for parallel analysis.
- **Timeout** (`timeout`): Timeout duration for analysis operations, default is 1 minute, set here to 5 minutes.
- **Issue Exit Code** (`issues-exit-code`): Exit code defaults to 1 if at least one issue is found.
- **Test Files** (`tests`): Whether to include test files, defaults to true.
- **Build Tags** (`build-tags`): Specify build tags used by all linters, defaults to an empty list. Example adds `mytag`.
- **Skip Directories** (`skip-dirs`): Configure which directories' issues are not reported, defaults to empty, but some default directories are independently skipped.
- **Skip Files** (`skip-files`): Specify files where issues should not be reported, supports regular expressions.
#### 10.2 Output Configuration
- **Format** (`format`): Set output format, default is "colored-line-number".
- **Print Issued Lines** (`print-issued-lines`): Whether to print the lines where issues occur, defaults to true.
- **Print Linter Name** (`print-linter-name`): Whether to print the linter name at the end of issue text, defaults to true.
- **Uniqueness Filter** (`uniq-by-line`): Whether to make issue outputs unique per line, defaults to true.
- **Path Prefix** (`path-prefix`): Prefix to add to output file references, defaults to no prefix.
- **Sort Results** (`sort-results`): Sort results by file path, line number, and column number.
#### 10.3 Linters Settings
In the configuration file, the `linters-settings` section allows detailed configuration of individual linters. Below are examples of specific linters settings and their purposes:
- **bidichk**: Used to check bidirectional text characters, ensuring correct display direction of text, especially when dealing with mixed left-to-right (LTR) and right-to-left (RTL) text.
- **dogsled**: Monitors excessive use of blank identifiers (`_`) in assignment operations, which may obscure data processing errors or unclear logic.
- **dupl**: Identifies duplicate code blocks, helping developers avoid code redundancy. The `threshold` parameter in settings allows adjustment of code similarity threshold triggering warnings.
- **errcheck**: Checks for unhandled errors. In Go, error handling is achieved by checking function return values. This linter helps ensure all errors are properly handled.
- **exhaustive**: Checks if `switch` statements include all possible values of an enum type, ensuring exhaustiveness of code. This helps avoid forgetting to handle certain cases.
#### 10.4 Example: `errcheck`
**Incorrect Code Example**:
```go
package main
import (
"fmt"
"os"
)
func main() {
f, _ := os.Open("filename.ext")
defer f.Close()
}
```
**Issue**: In the above code, the error return value of `os.Open` function is explicitly ignored. This is a common mistake as it may lead to unhandled errors and hard-to-trace bugs.
**Correct Form**:
```go
package main
import (
"fmt"
"os"
)
func main() {
f, err := os.Open("filename.ext")
if err != nil {
fmt.Printf("error opening file: %v\n", err)
return
}
defer f.Close()
}
```
In the correct form, by checking the error (`err`) returned by `os.Open`, we gracefully handle error cases rather than simply ignoring them.
#### 10.5 Example: `gofmt`
**Incorrect Code Example**:
```go
package main
import "fmt"
func main() {
fmt.Println("Hello, world!")
}
```
**Issue**: This code snippet doesn't follow Go's standard formatting rules, for example, incorrect indentation of `fmt.Println`.
**Correct Form**:
```go
package main
import "fmt"
func main() {
fmt.Println("Hello, world!")
}
```
Using `gofmt` tool can automatically fix such formatting issues, ensuring the code adheres to the coding standards of the Go community.
#### 10.6 Example: `unused`
**Incorrect Code Example**:
```go
package main
func helper() {}
func main() {}
```
**Issue**: The `helper` function is defined but not called anywhere, indicating potential redundant code or missing functionality implementation.
**Correct Form**:
```go
package main
// If the helper function is indeed needed, ensure it's used properly.
func helper() {
// Implement the function's functionality or ensure it's called elsewhere
}
func main() {
helper()
}
```
To improve the section on Linters settings in the document, we'll expand with more detailed explanations and reinforce understanding through examples.
#### 10.7 Example: `dogsled`
**Incorrect Code Example**:
```go
func getValues() (int, int, int) {
return 1, 2, 3
}
func main() {
_, _, val := getValues()
fmt.Println(val) // Only interested in the third return value
}
```
**Explanation**: In the above code, we use two blank identifiers to ignore the first two return values. Excessive use of blank identifiers can make code reading difficult.
**Improved Code**:
Consider refactoring the function or the usage of return values to reduce the need for blank identifiers or explicitly comment why ignoring certain values is safe.
#### 10.8: `exhaustive`
**Incorrect Code Example**:
```go
type Fruit int
const (
Apple Fruit = iota
Banana
Orange
)
func getFruitName(f Fruit) string {
switch f {
case Apple:
return "Apple"
case Banana:
return "Banana"
// Missing handling for Orange
}
return "Unknown"
}
```
**Explanation**: In this code, the `switch` statement doesn't cover all possible values of the `Fruit` type; the case for `Orange` is missing.
**Improved Code**:
```go
func getFruitName(f Fruit) string {
switch f {
case Apple:
return "Apple"
case Banana:
return "Banana"
case Orange:
return "Orange"
}
return "Unknown"
}
```
By adding the missing `case`, we ensure the `switch` statement is exhaustive, handling every possible enum value.
#### 10.9 Optimization of Configuration Files and Application of Code Analysis Tools
Through these examples, we demonstrate how to improve code quality by identifying and fixing common coding issues. OpenIM's configuration files allow developers to customize linters' behavior according to project requirements, ensuring code compliance with predefined quality standards and style guidelines.
By employing these tools and configuration strategies, teams can reduce the number of bugs, enhance code maintainability, and facilitate efficient collaboration during code review processes.
