Replace the bare SemanticallyEqual call in every frontend (CLI fmt, LSP
formatting + rangeFormatting) with format.VerifySafe, which runs four
checks before any formatted output is emitted:
- semantic equivalence - the code token stream is unchanged
- comment preservation - no -- or /* */ comment is dropped, merged,
split, reordered, or reworded (line endings / indentation normalised
away; recurses into dollar-quoted bodies)
- structural balance - the () [] and BEGIN/CASE/IF/LOOP...END nesting
profile matches, ignoring anything inside a comment or a string
- idempotence - a second format pass would not change it
On failure the CLI now prints the specific reason and keeps the original.
The comment check surfaced two real formatter bugs, both fixed in
formatBodyStatements:
- multi-line /* */ comments inside a PL/pgSQL body had their interior
lines re-split and reindented as if they were statements; they are
now tracked and carried verbatim with the opening line
- a column-0 -- line was glued onto the preceding line by the
split-line-join, which merged consecutive comment lines into one
Regenerate testdata/corpus/test_mm_proc.pgsql (was carrying the mangled
output). TestCorpusIdempotentAndSafe now runs the full VerifySafe bundle;
add safety_test.go with targeted cases.
* update error handling in various commands to use blank identifier
* enhance output formatting for better readability
* add golangci-lint to Makefile for linting checks
* Implement migration safety rules:
- MIG001: Warn on CREATE INDEX without CONCURRENT.
- MIG002: Warn on ALTER TABLE ADD COLUMN NOT NULL without DEFAULT.
- MIG003: Warn on ALTER TABLE ADD CONSTRAINT without NOT VALID.
* Implement naming conventions rules:
- NAM001: Warn on non-snake_case table names.
- NAM002: Warn on non-snake_case column names in CREATE TABLE.
- NAM003: Warn on non-snake_case function names.
* Add test fixtures for all new rules.
* Implemented `-d`/`--diff` flag to print unified diffs.
* Added `unifiedDiff` function for generating diffs.
* Config discovery now merges fields from `.pgtidy.yaml`.
