Fix False Positive with Require Schema Rule & Github Actions Output Clobbering

Added

• fmt: support comments in group by (#1194)

Fixed

• linter: fix github actions output clobbering json/gcc (#1192)

Fix Precommit Install & IDE Improvements

Fixed

• ci: fix precommit install by declaring optional dependencies (#1180)

• ide: fix select * w/ create view & more (#1184)

  The following now works correctly:

  create table t(a int);
  --             ^ dest
  create view v as table t;
  select a$0 from v;
  --     ^ src

• ide: treat select into like create table as (#1183)

  create table t(a bigint);
  --             ^ dest
  select * into u from t;
  select a from u;
  --     ^ src

• ide: fix column resolution with cte & shadowing (#1182)

  with outer_cte as (select 1 c)
  --                          ^ dest
  select * from (
    with inner_cte as (select 2 d)
    select c from outer_cte
  --       ^ src
  ) s;

• ide: fix aliases not hiding original name (#1181)

• ide: fix cte & alias resolution (#1179)

    with
      a as (select * from b),
  --                      ^ src doesn't resolve
      b as (select 1 x)
    select * from a;

• ide: don't resolve trailing FromItems in a lateral subquery (#1177)

  with
    d as (select 1 id, 2 amount),
    c as (select 2 id)
  select r.amount
  from
    d,
    lateral (
      select d.amount
      from d
      where d.id = c.id
      --           ^ src doesn't resolve
      limit 1
    ) r,
    c;

Parser Improvements & Fixes + Error Docs Hyperlinks

Added

• parser: validation for default usages (#1175)

  -- ok
  insert into t values (default);

  -- err
  select default;

• linter: setup hyperlinks for rule names in terminal (#1174)

  If your terminal supports it, then clicking on the rule name will navigate
  you to the docs.

Fixed

• fmt: upgrade tiny_pretty to latest (#1173)

  We no longer wrap statements unless necessary.

• parser: fix parsing period column (#1172)

  previously we'd error on:

  create table t (
    symbol text,
    period text,
    year int,
    quarter int,
    primary key (symbol, period, year, quarter)
  );

• ide: add hover for string literals (#1155)

  Now we decode the escape sequences for string literals on hover and show the
  value up to the first new line.

• ide: improve numeric literal type inference (#1156)

  select 2147483647; -- type: integer
  select 2147483648; -- type: bigint

  select
    x'AF';

• fmt: unquote column aliases when possible (#1168)

Improved Parser Validation for Strings + Updated Install Method

Added

• parser: validation for bit, byte, and escape string types (#1132)

  select b'01' '10';
  select x'0F' '10';
  select e'foo' 'bar';

  now gives:

  error[syntax-error]: Expected new line or comma between string literals
    ╭▸ stdin:1:13

    ╰╴                   ━━━

Changed

• ci: update npm based install method (#1133)

  Instead of fetching the binary via an install script we use an optional
  peer dependency, mirroring ESBuild and Sentry.

Fixed

• cli: fix missing binary exit code (#1130)

  Before if the install script didn't run the NPM JS shim would exit without
  erroring. Thanks @nwalters512!

• parser: parsing unicode escape idents in cast position (#1127)

  select 2::U&"!0069!006E!0074!0038" UESCAPE '!' from t;

  now parses without error

v2.51.0 - 2026-05-06

Added

• linter: add file-level override to disable assume_in_transaction (#996). Thanks @reteps!

  When using assume-in-transaction, you can disable it on a per file basis using a comment:

  -- squawk-disable-assume-in-transaction

• syntax: add validation for select into (#1116)

  Warn about invalid usages, such as:

  • select 4 a union select 5 a into t;
  • with t as (select 1 a into t) select * from t;
  • select * from t where a in (select 1 a into t);

  and more!

• parser: add empty statement to ast (#1111)

  ;
  ;
  ;

  now gives:

  SOURCE_FILE@0..5
    EMPTY_STMT@0..1
      SEMICOLON@0..1 ";"
    WHITESPACE@1..2 "\n"
    EMPTY_STMT@2..3
      SEMICOLON@2..3 ";"
    WHITESPACE@3..4 "\n"
    EMPTY_STMT@4..5
      SEMICOLON@4..5 ";"
  

• ide: code actions create table as <-> select into + parser fix (#1113)

  Create table and select into are roughly interchangable, so this code action
  supports switching between.

• ide: hover infer more types for columns (#1109, #1108)

Changed
