# sqlfmt CHANGELOG
All notable changes to this project will be documented in this file.
## [Unreleased]
### Formatting Changes + Bug Fixes
- sqlfmt now removes extra blank lines ([#249](https://github.com/tconbeer/sqlfmt/issues/313) - thank you, [@nfcampos](https://github.com/nfcampos)!). Basically, no more than 1 blank line inside queries or blocks; no more than 2 between queries or blocks.
- sqlfmt now supports `create ... clone` statements ([#313](https://github.com/tconbeer/sqlfmt/issues/313)).
- sqlfmt will now format all files that end with `*.sql` and `*.sql.jinja`, even those with other dots in their filenames ([#354](https://github.com/tconbeer/sqlfmt/issues/354) - thank you [@ysmilda](https://github.com/ysmilda)!).
- fixed a bug where `{% call %}` blocks with arguments like `{% call(foo) bar(baz) %}` would cause a parsing error ([#353](https://github.com/tconbeer/sqlfmt/issues/353) - thank you [@IgnorantWalking](https://github.com/IgnorantWalking)!).
- sqlfmt now supports [bun placeholders](https://bun.uptrace.dev/guide/placeholders.html) ([#356](https://github.com/tconbeer/sqlfmt/issues/356) - thank you [@ysmilda](https://github.com/ysmilda)!)
### Features
- by default, sqlfmt now runs an additional safety check that parses the formatted output to ensure it contains all of the same content as the raw input. This incurs a slight (~20%) performance penalty. To bypass this safety check, you can use the command line option `--fast`, the corresponding TOML or environment variable config, or pass `Mode(fast=True)` to any API method. The safety check is automatically bypassed if sqlfmt is run with the `--check` or `--diff` options. If the safety check fails, the CLI will include an error in the report, and the `format_string` API will raise a `SqlfmtEquivalenceError`, which is a subclass of `SqlfmtError`.
## [0.14.3] - 2023-01-05
### Formatting Changes + Bug Fixes
- fixed a bug where very long lines could raise `RecursionError` ([#343](https://github.com/tconbeer/sqlfmt/issues/343) - thank you [@kcem-flyr](https://github.com/kcem-flyr)!).
## [0.14.2] - 2022-12-12
### Formatting Changes + Bug Fixes
- fixed a bug where nested `{% set %}` and `{% call %}` blocks would cause a parsing error ([#338](https://github.com/tconbeer/sqlfmt/issues/338) - thank you [@AndrewLane](https://github.com/AndrewLane)!).
## [0.14.1] - 2022-12-06
### Formatting Changes + Bug Fixes
- sqlfmt now supports `is [not] distinct from` as a word operator ([#327](https://github.com/tconbeer/sqlfmt/issues/327) - thank you [@IgnorantWalking](https://github.com/IgnorantWalking), [@kadekillary](https://github.com/kadekillary)!).
- fixed a bug where jinja `{% call %}` blocks that called a macro that wasn't `statement` caused a parsing error ([#335](https://github.com/tconbeer/sqlfmt/issues/335) - thank you [@AndrewLane](https://github.com/AndrewLane)!).
### Performance
- sqlfmt runs finish in 20% less time due to algorithmic improvements
## [0.14.0] - 2022-11-30
### Formatting Changes + Bug Fixes
- sqlfmt now supports `{% materialization ... %}` and `{% call statement(...) %}` blocks ([#309](https://github.com/tconbeer/sqlfmt/issues/309)).
- sqlfmt now resets the SQL depth of a query after encountering an `{% endmacro %}`, `{% endtest %}`, `{% endcall %}`, or `{% endmaterialization %}` tag.
- sqlfmt now supports `create warehouse` and `alter warehouse` statements ([#312](https://github.com/tconbeer/sqlfmt/issues/312), [#299](https://github.com/tconbeer/sqlfmt/issues/312)).
- sqlfmt now supports `alter function` and `drop function` statements ([#310](https://github.com/tconbeer/sqlfmt/issues/310), [#311](https://github.com/tconbeer/sqlfmt/issues/311)), and Snowflake's `create external function` statements ([#322](https://github.com/tconbeer/sqlfmt/issues/322)).
- sqlfmt better supports numeric constants (number literals), including those using scientific notation (e.g., `1.5e-9`) and the unary `+` or `-` operators (e.g., `+3`), and is now smarter about when the `-` symbol is the unary negative or binary subtraction operator. ([#321](https://github.com/tconbeer/sqlfmt/issues/321) - thank you [@liaopeiyuan](https://github.com/liaopeiyuan)!).
- fixed a bug where we added extra whitespace to the end of empty comment lines ([#319](https://github.com/tconbeer/sqlfmt/issues/319) - thank you [@eherde](https://github.com/eherde)!).
- fixed an bug where wrapping unsupported DDL in jinja would cause a parsing error ([#326](https://github.com/tconbeer/sqlfmt/issues/326) - thank you [@ETG-msimons](https://github.com/ETG-msimons)!). Also improved parsing of unsupported DDL and made false positives less likely.
- fixed a bug where we could have unsafely run _black_ against jinja that contained Python keywords and their safe alternatives (e.g., `return(return_())`).
- fixed a bug where we deleted some extra whitespace lines (and in very rare cases, nonblank lines)
- fixed a bug where Python recursion limits could cause incorrect formatting in rare cases
## [0.13.0] - 2022-11-01
### Formatting Changes + Bug Fixes
- sqlfmt now supports `delete` statements and the associated keywords `using` and `returning` ([#281](https://github.com/tconbeer/sqlfmt/issues/281)).
- sqlfmt now supports `grant` and `revoke` statements and all associated keywords ([#283](https://github.com/tconbeer/sqlfmt/issues/283)).
- sqlfmt now supports `create function` statements and all associated keywords ([#282](https://github.com/tconbeer/sqlfmt/issues/282)).
- sqlfmt now supports the `explain` keyword ([#280](https://github.com/tconbeer/sqlfmt/issues/280)).
- sqlfmt now supports BigQuery typed table and struct definitions and literals, like `table`.
- sqlfmt now supports variables like `$foo` as ordinary identifiers.
### Features
- sqlfmt is now tested against Python 3.11 ([#242](https://github.com/tconbeer/sqlfmt/issues/242)). Previous versions of sqlfmt are also compatible.
with Python 3.11. When installed in 3.11, sqlfmt no longer requires the `tomli` dependency.
## [0.12.0] - 2022-10-14
### Formatting Changes + Bug Fixes
- DDL and DML statements (`create`, `insert`, `grant`, etc.) will no longer be formatted ([#243](https://github.com/tconbeer/sqlfmt/issues/243)).
These statements were never supported by sqlfmt, and the existing algorithm produced bad formatting. Support for DDL and DML statements will be gradually added back in in future versions.
For more information, see the [tracking issue for DDL support](https://github.com/tconbeer/sqlfmt/issues/262).
- BigQuery typed array literals like `array[1, 2]` are now supported, and spaces will no longer be inserted around `<` and `>` ([#212](https://github.com/tconbeer/sqlfmt/issues/212)).
- SparkSQL-specific keywords `tablesample`, `cluster by`, `distribute by`, `sort by`, and `lateral view` are now supported by the polyglot dialect ([#264](https://github.com/tconbeer/sqlfmt/issues/264)).
- `pivot` and `unpivot` are now supported as word operators, and will have a space between the keyword and the following parentheses.
- `values` is now supported as an unterminated keyword; tuples of values will be indented from the `values` keyword if they span more than one line ([#263](https://github.com/tconbeer/sqlfmt/issues/263)).
## [0.11.1] - 2022-09-17
### Features
- Any CLI option can now be configured using environment variables. Variable names are prefixed by `SQLFMT` and are the `SHOUTING_CASE` spelling of the options. For example, `sqlfmt . --line-length 100` is equivalent to `SQLFMT_LINE_LENGTH=100 sqlfmt .` ([#251](https://github.com/tconbeer/sqlfmt/issues/251)).
### Documentation
- The README has been shortened and now links to [docs.sqlfmt.com](https://docs.sqlfmt.com).
## [0.11.0] - 2022-08-21
### Breaking API Changes
- The `files` argument of `api.run` is now a `Collection[pathlib.Path]` that represents an exact collection of files to be formatted, instead of a list of paths to search for files. Use `api.get_matching_paths(paths, mode)` to return the set of exact paths expected by `api.run`.
### Features
- sqlfmt will now display a progress bar for long runs ([#231](https://github.com/tconbeer/sqlfmt/pull/231)). You can disable this with the `--no-progressbar` option.
- `api.run` now accepts an optional `callback` argument, which must be a `Callable[[Awaitable[SqlFormatResult]], None]`. Unless the `--single-process` option is used, the callback is executed after each file is formatted.
- sqlfmt can now be called as a python module, with `python -m sqlfmt`.
### Formatting Changes + Bug Fixes
- adds more granularity to operator precedence and will merge lines more aggressively that start with high-precedence operators ([#200](https://github.com/tconbeer/sqlfmt/issues/200)).
- improves the formatting of `between ... and ...`, especially in situations where the source includes a line break ([#207](https://github.com/tconbeer/sqlfmt/issues/207)).
- improves the consistency of formatting long chains of operators that include parentheses ([#214](https://github.com/tconbeer/sqlfmt/issues/214)).
- fixes a bug that caused unnecessary copying of the cache when using multiprocessing. Large projects should see dramatically faster (near-instant) runs once the cache is warm.
- fixes a bug that could cause lines with long jinja tags to be one character over the line length limit, and could result in unstable formatting ([#237](https://github.com/tconbeer/sqlfmt/issues/237) - thank you [@nfcampos](https://github.com/nfcampos)!).
- fixes a bug that formatted array literals like they were indexing operations ([#235](https://github.com/tconbeer/sqlfmt/issues/235) - thank you [@nfcampos](https://github.com/nfcampos)!).
## [0.10.1] - 2022-08-05
### Features
- sqlfmt now supports the psycopg placeholders `%s` and `%(name)s` ([#198](https://github.com/tconbeer/sqlfmt/issues/198) - thank you [@snorkysnark](https://github.com/snorkysnark)!).
### Formatting Changes + Bug Fixes
- sqlfmt now standardizes whitespace inside word tokens ([#201](https://github.com/tconbeer/sqlfmt/issues/201)).
- `using` is now treated as a word operator. It gets a space before its brackets and merging with surrounding lines is now much improved ([#218](https://github.com/tconbeer/sqlfmt/issues/218) - thank you [@nfcampos](https://github.com/nfcampos)!).
- `within group` and `filter` are now treated like `over`, and the formatting of those aggregate clauses is improved ([#205](https://github.com/tconbeer/sqlfmt/issues/205)).
## [0.10.0] - 2022-08-02
### Features
- sqlfmt now supports ClickHouse. When run with the `--dialect clickhouse` option, sqlfmt will not lowercase names that could be case-sensitive in ClickHouse, like function names, aliases, etc. ([#193](https://github.com/tconbeer/sqlfmt/issues/193) - thank you [@Shlomixg](https://github.com/Shlomixg)!).
### Formatting Changes + Bug Fixes
- formatting for chained boolean operators with complex expressions is now significantly improved ([#189](https://github.com/tconbeer/sqlfmt/issues/189) - thank you [@Rainymood](https://github.com/Rainymood)!).
- formatting for array indexing is now significantly improved ([#209](https://github.com/tconbeer/sqlfmt/issues/209)) and sqlfmt no longer inserts spaces between the `offset()` function and its brackets.
- set operators (like `union`) are now formatted differently. They must be on their own line, and will not cause subsequent blocks to be indented ([#188](https://github.com/tconbeer/sqlfmt/issues/188) - thank you [@Rainymood](https://github.com/Rainymood)!).
- `select * except (...)` syntax is now explicitly supported, and formatting is improved. Support added for BigQuery and DuckDB star options: `except`, `exclude`, `replace`.
- sqlfmt no longer inserts spaces between nested or repeated brackets, like `(())` or `()[]`.
- a bug causing unstable formatting with long/multiline jinja tags has been fixed ([#175](https://github.com/tconbeer/sqlfmt/issues/175)).
## [0.9.0] - 2022-06-02
### Features
- jinjafmt is now able to format jinja that contains functions and variables that are reserved python words (e.g., return, except, from) ([#177](https://github.com/tconbeer/sqlfmt/issues/177), [#155](https://github.com/tconbeer/sqlfmt/issues/155)), and `~`, the jinja string concatenation operator ([#182](https://github.com/tconbeer/sqlfmt/issues/182))
- adds a new command-line option to reset the sqlfmt cache ([#184](https://github.com/tconbeer/sqlfmt/issues/184))
### Fixes
- fixes issue where jinjafmt would insert a trailing comma into multiline macro definitions, causing dbt compiling errors ([#156](https://github.com/tconbeer/sqlfmt/issues/156))
- fixes issue causing unstable formatting of multiline jinja tags when black is unable to parse the tag ([#176](https://github.com/tconbeer/sqlfmt/issues/176))
- fixes issue for developers where pre-commit hooks would not install
### Primer
- sqlfmt_primer now runs against forked (formatted) repos to make changes easier to detect
## [0.8.0] - 2022-05-04
### Formatting Changes
- sqlfmt is now more conservative about preserving whitespace around jinja expressions when we remove newlines ([#162](https://github.com/tconbeer/sqlfmt/issues/162), [#165](https://github.com/tconbeer/sqlfmt/issues/165) - thank you [@rcaddell](https://github.com/rcaddell) and [@rjay98](https://github.com/rjay98)!)
- jinja blocks are now dedented before line merging, instead of after. This results in small changes to formatted output in some cases where jinja blocks are used
- fixes an issue where jinja else and elif statements could cause unstable formatting. May impact whitespace for the tokens following `{% else %}` and `{% elif %}` statements
## [0.7.0] - 2022-04-24
### Breaking Changes
- api.run now accepts `files` as a `List[pathlib.Path]` instead of a `List[str]`
### Features
- any command line option can now be set in a `pyproject.toml` file. See `README` for more information ([#90](https://github.com/tconbeer/sqlfmt/issues/90))
- sqlfmt now accepts an `--exclude` option to specify a glob of files to exclude from formatting ([#131](https://github.com/tconbeer/sqlfmt/issues/131))
## [0.6.0] - 2022-03-21
### Formatting Fixes
- adds support for snapshot blocks, so the contents of those blocks are now properly formatted ([#137](https://github.com/tconbeer/sqlfmt/issues/137))
- fixes issue causing unstable formatting of multiline jinja tags when black is not installed ([#138](https://github.com/tconbeer/sqlfmt/issues/138))
- fixes formatting of semicolons and semicolon-delimited queries ([#132](https://github.com/tconbeer/sqlfmt/issues/132))
## [0.5.1] - 2022-02-08
### Fixes
- adds support for numbered field references (e.g., `$1`) and snowflake stages (`@my_stage`) as identifiers
- do not split lines before the `between` operator's `and` keyword ([#124](https://github.com/tconbeer/sqlfmt/issues/124) - thank you [@WestComputing](https://github.com/WestComputing)!)
## [0.5.0] - 2022-02-02
### Formatting changes
- formats the contents of jinja tags (the code between the curlies) using _black_, the Python formatter. If _black_ is not already installed, you can use this feature by re-installing sqlfmt with the jinjafmt extra (`pipx install sqlfmt[jinjafmt]`). If _black_ is installed, but you do not want to use this feature, you can disable it with the command-line option `--no-jinjafmt`
- no longer inserts spaces around colons ([#103](https://github.com/tconbeer/sqlfmt/issues/103) - thank you [@noel](https://github.com/noel)!)
### Fixes
- adds "cross join" to list of supported join types. No longer merges the "cross" keyword with the previous statement ([#110](https://github.com/tconbeer/sqlfmt/issues/110) - thank you [@rdeese](https://github.com/rdeese)!)
- adds support for every valid operator in postgresql, even the weird ones, like `@>`, `||/`, `?-|` ([#105](https://github.com/tconbeer/sqlfmt/issues/105))
## [0.4.3] - 2022-01-31
### Fixes
- removes an unnecessary dependency on black that broke installation ([#98](https://github.com/tconbeer/sqlfmt/issues/98) - thank you [@ljhopkins2](https://github.com/ljhopkins2)!)

### Fixes
- supports all postgres and bigquery string literals and quoted identifiers, including triple quotes, escaped quotes, dollar-delimited, etc.
- no longer fails with a parsing error when encountering a semicolon
- properly delineates between "\*" as "all fields" and as the multiplication operator
## [0.2.1] - 2021-12-04
