Overview

Rule groups allow for easier configuration of rules that perform similar functions. Using rule groups can make upgrading VSG versions easier as new rules are added.

The following is a list of the rule groups:

Group	Description
alignment	Horizontal alignment rules.
blank_line	Vertical alignment rules.
case	All rules involving lower and upper casing.
case::keyword	Casing rules for VHDL keywords.
case::label	Casing rules for labels.
case::name	Casing rules for identifiers, etc…
length	Rules restricting length.
indent	Rules involving line indents.
naming	Rules for constraining how identifiers etc.. are named.
structure	Rules dictating the structure of the code.
structure::optional	Rules for optional VHDL language items.
whitespace	Rules for managing whitespace.

Subgroups

Groups with double colons (::) are considered subgroups. This allows for finer control of group rules.

For example, the case of keywords, labels and names can be set independently.

Configuring Groups

Refer to the section Configuring a Rule Group for information on how to configure rule groups.
