## POSIX shell
|
||
|
|
|
||
|
|
- [Style guide](https://google.github.io/styleguide/shell.xml)

|
## Go

|
- Know and avoid [Go landmines](https://gist.github.com/lavalamp/4bd23295a9f32706a48f)
|
||
|
|
- Comment your code.
|
||
|
|
- [Go's commenting conventions](http://blog.golang.org/godoc-documenting-go-code)
|
||
|
|
- If reviewers ask questions about why the code is the way it is, that's a sign that comments might be helpful.
|
||
|
|
- Command-line flags should use dashes, not underscores
|
||
|
|
- Naming
|
||
|
|
- Please consider package name when selecting an interface name, and avoid redundancy. For example, `storage.Interface` is better than `storage.StorageInterface`.
|
||
|
|
- Do not use uppercase characters, underscores, or dashes in package names.
|
||
|
|
- Please consider parent directory name when choosing a package name. For example, `pkg/controllers/autoscaler/foo.go` should say `package autoscaler` not `package autoscalercontroller`.
|
||
|
|
- Unless there's a good reason, the `package foo` line should match the name of the directory in which the `.go` file exists.
|
||
|
|
- Importers can use a different name if they need to disambiguate.
|
||
|
|
|
||
|
|
## Directory and file conventions
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
## Testing conventions
|
||
|
|
|
||
|
|
Please refer to [TESTING.md](../../tests/TESTING.md) document.
