Emacs in particluar does some indenting where it will try to align
continued lines up with the first argument, e.g.
a_long_command arg1 \
arg2 arg3
Our current check will just barf on this when the offset isn't a
multiple of 4. By passing "logical_line" to the offset checker, we
can find the first argument on the first line, and allow the whole
thing through if everything lines up.

bashate
A pep8 equivalent for bash scripts
This program attempts to be an automated style checker for bash scripts to fill the same part of code review that pep8 does in most OpenStack projects. It started from humble beginnings in the DevStack project, and will continue to evolve over time.

Currently Supported Checks
Errors
Basic white space errors, for consistent indenting
- E001: check that lines do not end with trailing whitespace
- E002: ensure that indents are only spaces, and not hard tabs
- E003: ensure all indents are a multiple of 4 spaces
- E004: file did not end with a newline
- E006: check for lines longer than 79 columns
Structure Errors
A set of rules that help keep things consistent in control blocks. These are ignored on long lines that have a continuation, because unrolling that is kind of "interesting"
- E010: do not on the same line as for
- E011: then not on the same line as if or elif
- E012: heredoc didn't end before EOF
- E020: Function declaration not in format
^function name {$
Obsolete, deprecated or unsafe syntax
Rules to identify obsolete, deprecated or unsafe syntax that should not be used
- E040: Syntax errors reported by bash -n
- E041: Usage of $[ for arithmetic is deprecated for $((
- E042: local declaration hides errors
