# Style Guide
|
|
|
|
The majority of our style recommendations are automatically enforced via our
|
|
automated linters. This document has guidelines that are less easy to lint for.
|
|
|
|
## Shell scripts
|
|
|
|
Shell scripts are OK for small tasks or wrappers, but prefer to use Python for
|
|
anything with a hint of complexity or in general.
|
|
|
|
Shell scripts should be written against bash, starting with this shebang:
|
|
```
|
|
#!/usr/bin/env bash
|
|
```
|
|
|
|
Note that the version of bash available on OS X by default is quite old, so be
|
|
careful when using new features.
|
|
|
|
Scripts should enable a few options at the top for robustness:
|
|
```
|
|
set -o errexit
|
|
set -o nounset
|
|
set -o pipefail
|
|
```
|
|
|
|
Quote all variables, using the full form: `"${SOME_VARIABLE}"`.
|
|
|
|
Use `"$(some-command)"` instead of backticks for command substitution. Note
|
|
that these should be quoted as well.
