Crate sql_dialect_fmt_lint 

Lint rules for SQL, independent of any editor protocol.

lint (and its options/dialect-aware variants) checks source text against the SDF rule set and returns LintDiagnostics located at byte ranges, so the CLI can render path:line:col findings and the language server can convert them to LSP diagnostics without this crate ever depending on LSP types.

Rules

code	rule
SDF001	SELECT * in a select list
SDF002	large literal IN (...) list
SDF003	unsupported embedded LANGUAGE ... AS $$...$$
SDF004	DELETE without WHERE
SDF005	UPDATE without WHERE
SDF006	comma join in FROM (implicit cross join)
SDF007	ORDER BY ordinal (e.g. ORDER BY 1)

Suppression

A finding is suppressed by a line comment on the previous line:

-- sql-dialect-fmt: disable-next-line SDF001
SELECT * FROM t;

Omitting the code (or writing all/lint) suppresses every rule for the next line.

Structs

LintDiagnostic

One lint finding, located at a byte range into the linted source text.

LintOptions

Lint knobs. Every rule is on by default; each can be disabled independently.

Enums

Dialect

The SQL dialect a lex/parse/format request targets.

LintCode

The stable identity of a lint rule; rendered as SDFxxx via LintCode::as_str.

LintSeverity

How severe a finding is. Every current rule emits LintSeverity::Warning.

Functions

lint

Lint text as Snowflake SQL with default LintOptions.

lint_with_dialect

Lint text as dialect, honoring options and suppression comments. Findings are sorted by source position.

lint_with_options

Lint text as Snowflake SQL with explicit options.
