gudusoft.gsqlparser.pp2.layout.rules.SpacingRules

All Implemented Interfaces:

LayoutRule

public final class SpacingRules
extends Object
implements LayoutRule

The base spacing rule: requests the number of blank columns before each token so adjacent tokens are separated by a single space, with the usual tight exceptions around parentheses, commas, periods, and semicolons.

Spacing model (per adjacent token pair)

• 0 after an open paren ( and before a close paren );
• 0 before a comma or semicolon;
• 0 around a period (qualified names a.b);
• 0 before an open paren ( (function calls and groups stay tight — keyword-introduced groups are re-spaced by the higher-priority S26 rule);
• 1 otherwise (operators, keywords, identifiers, *).

This is the lowest-priority layout rule (LayoutPriorities.SPACING), so later rules (clause linebreaks, indent, alignment) override its decisions where they apply. It only sets blanksBefore; linebreaks/indent are other rules' concern. Spacing around comment tokens is left to the original whitespace (untouched) to avoid disturbing comment placement.

Iterative single pass; read-only over tokens. Plan reference: §7.3/S24, §7.4/S24.
