sqlfmt CHANGELOG

All notable changes to this project will be documented in this file.

Unreleased

0.13.0 - 2022-11-01

Formatting Changes + Bug Fixes

• sqlfmt now supports delete statements and the associated keywords using and returning (#281)
• sqlfmt now supports grant and revoke statements and all associated keywords (#283)
• sqlfmt now supports create function statements and all associated keywords (#282)
• sqlfmt now supports the explain keyword (#280)
• sqlfmt now supports BigQuery typed table and struct definitions and literals, like table<a int64, b bytes(5), c string>
• sqlfmt now supports variables like $foo as ordinary identifiers

Features

• sqlfmt is now tested against Python 3.11 (#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).
  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.
• BigQuery typed array literals like array<float64>[1, 2] are now supported, and spaces will no longer be inserted around < and > (#212)
• SparkSQL-specific keywords tablesample, cluster by, distribute by, sort by, and lateral view are now supported by the polyglot dialect (#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)

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).

Documentation

• The README has been shortened and now links to 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). 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)
• improves the formatting of between ... and ..., especially in situations where the source includes a line break (#207)
• improves the consistency of formatting long chains of operators that include parentheses (#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 - thank you @nfcampos!)
• fixes a bug that formatted array literals like they were indexing operations (#235 - thank you @nfcampos!)

0.10.1 - 2022-08-05

Features

• sqlfmt now supports the psycopg placeholders %s and %(name)s (#198 - thank you @snorkysnark!)

Formatting Changes + Bug Fixes

• sqlfmt now standardizes whitespace inside word tokens (#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 - thank you @nfcampos!)
• within group and filter are now treated like over, and the formatting of those aggregate clauses is improved (#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 - thank you @Shlomixg!)

Formatting Changes + Bug Fixes

• formatting for chained boolean operators with complex expressions is now significantly improved (#189 - thank you @Rainymood!)
• formatting for array indexing is now significantly improved (#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 - thank you @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)

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, #155), and ~, the jinja string concatenation operator (#182)
• adds a new command-line option to reset the sqlfmt cache (#184)

Fixes

• fixes issue where jinjafmt would insert a trailing comma into multiline macro definitions, causing dbt compiling errors (#156)
• fixes issue causing unstable formatting of multiline jinja tags when black is unable to parse the tag (#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, #165 - thank you @rcaddell and @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)
• sqlfmt now accepts an --exclude option to specify a glob of files to exclude from formatting (#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)
• fixes issue causing unstable formatting of multiline jinja tags when black is not installed (#138)
• fixes formatting of semicolons and semicolon-delimited queries (#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 - thank you @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 - thank you @noel!)

Fixes

• adds "cross join" to list of supported join types. No longer merges the "cross" keyword with the previous statement (#110 - thank you @rdeese!)
• adds support for every valid operator in postgresql, even the weird ones, like @>, ||/, ?-| (#105)

0.4.3 - 2022-01-31

Fixes

• removes an unnecessary dependency on black that broke installation (#98 - thank you @ljhopkins2!)

0.4.2 - 2022-01-26

Features

• adds an option, --single-process, to force single-processing, even when formatting many files

Under the Hood

• when formatting multiple files, uses multiprocessing for ~3x faster throughput

0.4.1 - 2022-01-20

Formatting changes

• preserves leading and trailing blank lines when merging lines with content
• no longer prints whitespace on blank lines

0.4.0 - 2022-01-20

Formatting changes

• adds special support for jinja, with new formatting rules for jinja statements, expressions, and blocks
• safely standardizes whitespace around jinja statements and expressions
• merges lines within and across jinja blocks while balancing start/end statements
• jinja block tags can no longr be indented farther than any of their contents

Features

• developers can now easily profile sqlfmt performance (after installing the sqlfmt_primer extra) with make profiling

Fixes

• no longer fails with a parsing error if "end" is used as a name in the query

Under the Hood

• refactors lexing using typical callable architecture for more flexibility
• adds new token types for jinja statements and blocks
• refactors calculation of node and line depth to include jinja blocks
• adds some caching to line properties for performance enhancements

0.3.0 - 2021-12-16

Formatting changes

• standardizes comments and splits long comments onto multiple lines if necessary
• improves splitting and merging of lines with operators (like "+", "as", "on", etc.)
• improves formatting of queries that use leading commas
• improves merging of statements with chained brackets ("( something ) + ( something_else )" )

Features

• adds a simple cache and skips formatting files that have not changed since last successful run
• improves the welcome message displayed when running sqlfmt with no arguments

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

Performance

• supports back-ticks for quoting relation names
• supports MySQL-style comments (# comment)
• adds a new cli tool, sqlfmt_primer, to run sqlfmt against known OSS projects to gauge changes

Fixes
