## Unreleased
* Don't error when the `JavaScriptFFI` language pragma is present. [Issue
1087](https://github.com/tweag/ormolu/issues/1087).
* Improve comment placement in if-then-else blocks. [Issue
998](https://github.com/tweag/ormolu/issues/998).
* Now command line options for fixity overrides and module re-exports
overwrite information from `.ormolu` files. [Issue
1030](https://github.com/tweag/ormolu/issues/1030).
2023-10-24 21:52:07 +03:00
## Ormolu 0.7.3.0
2023-07-30 17:05:07 +03:00
* Switched to `ghc-lib-parser-9.8`, with the following new syntactic features:
* `ExtendedLiterals`: `123#Int8` is a literal of type `Int8#`. (disabled by
default)
* `TypeAbstractions`: `@k`-binders in data type declarations (enabled by
default)
* GHC proposal [#134](https://github.com/ghc-proposals/ghc-proposals/blob/0b652bd70258e354dfe4a05940182007596f8bf7/proposals/0134-deprecating-exports-proposal.rst): deprecating/warning about exports
* GHC proposal [#541](https://github.com/ghc-proposals/ghc-proposals/blob/0b652bd70258e354dfe4a05940182007596f8bf7/proposals/0541-warning-pragmas-with-categories.rst): warning categories
2023-09-06 18:31:21 +03:00
## Ormolu 0.7.2.0
* Preserve necessary braces for final function arguments. [Issue
1044](https://github.com/tweag/ormolu/issues/1044).
* Put `"this"` `PackageImports` at the end. [Issue
1048](https://github.com/tweag/ormolu/issues/1048).
* Format parenthesized operators starting with a `#` correctly in the presence
of `UnboxedSums`. [Issue 1062](https://github.com/tweag/ormolu/issues/1062).
* Fix false positives in AST diffing related to empty Haddock comments in data
declarations. [Issue 1065](https://github.com/tweag/ormolu/issues/1065).
## Ormolu 0.7.1.0
* Include `base` fixity information when formatting a Haskell file that's
not mentioned in an existing cabal file. [Issue
1032](https://github.com/tweag/ormolu/issues/1032)
* Update `displayException` for `OrmoluException` to pretty print the
exception. [PR 1031](https://github.com/tweag/ormolu/pull/1031).
* Ormolu is now aware of more common module re-exports by default.
* Support explicit mention of target package name in module re-exports. Even
if the exported package is not specified as a direct dependency of the
component being formatted it will still be taken into account correctly.
[Issue 1037](https://github.com/tweag/ormolu/issues/1037).
* Ormolu no longer fails when CPP directly follows the import section (a
regression introduced in 0.7.0.0). [Issue
1040](https://github.com/tweag/ormolu/issues/1040).
2023-05-17 22:59:53 +03:00
## Ormolu 0.7.0.0
* Inference of operator fixity information is now more precise and takes
into account the import section of the module being formatted. [Issue
892](https://github.com/tweag/ormolu/issues/892) and [issue
929](https://github.com/tweag/ormolu/issues/929).
* Ormolu can now be made aware of module re-exports through either special
declarations in `.ormolu` files (see the readme for a description of the
syntax), or on the command line with the `--reexport`/`-r` option. [Issue
1017](https://github.com/tweag/ormolu/issues/1017).
* Ormolu now looks for `.ormolu` files independently of `.cabal` files. This
means that it is now possible to have one `.ormolu` file for multiple
Cabal packages. [Issue 1019](https://github.com/tweag/ormolu/issues/1019).
* Consistently format `do` blocks/`case`s/`MultiWayIf`s with 4 spaces if and
only if they occur as the applicand. [Issue
1002](https://github.com/tweag/ormolu/issues/1002) and [issue
730](https://github.com/tweag/ormolu/issues/730).
2023-04-23 23:12:33 +03:00
* Support the (deprecated) `DatatypeContexts` extension to avoid surprises.
[Issue 1012](https://github.com/tweag/ormolu/issues/1012).
* Don't let comments escape from empty export lists. [Issue
906](https://github.com/tweag/ormolu/issues/906).
* Format `\cases` with multiple patterns across multiple lines correctly. [Issue
1025](https://github.com/tweag/ormolu/issues/1025).
2023-04-04 19:24:44 +03:00
## Ormolu 0.6.0.1
* Fix false positives in AST diffing related to `UnicodeSyntax`. [PR
1009](https://github.com/tweag/ormolu/pull/1009).
2023-04-03 16:51:26 +03:00
## Ormolu 0.6.0.0
* Haddocks attached to arguments of a data constructor are now formatted in
the pipe style (rather than the caret style), consistent with everything
else. As a consequence, now Ormolu's output will be deemed invalid by the
Haddock shipped with GHC <9.0. [Issue
844](https://github.com/tweag/ormolu/issues/844) and [issue
828](https://github.com/tweag/ormolu/issues/828).
* Insert space before char literals in ticked promoted constructs when
necessary. [Issue 1000](https://github.com/tweag/ormolu/issues/1000).
2023-01-28 17:22:07 +03:00
* Switched to `ghc-lib-parser-9.6`:
* Extended `OverloadedLabels`: `#Foo`, `#3`, `#"Hello there"`.
Also, it is now disabled by default, as it causes e.g. `a#b` to be parsed
differently.
* New extension: `TypeData`, enabled by default.
* Parse errors now include error codes, cf. https://errors.haskell.org.
* Updated to `Cabal-syntax-3.10`.
* Now whenever Ormolu fails to parse a `.cabal` file it also explains why.
[PR 999](https://github.com/tweag/ormolu/pull/999).
2023-01-26 16:30:23 +03:00
## Ormolu 0.5.3.0
2023-01-06 16:40:38 +03:00
* Stop making empty `let`s move comments. [Issue
917](https://github.com/tweag/ormolu/issues/917).
* Now `.ormolu` fixity override files can use both LF and CRLF line endings.
[PR 969](https://github.com/tweag/ormolu/pull/969).
2023-01-19 16:35:42 +03:00
* Normalize parentheses around constraints. [Issue
264](https://github.com/tweag/ormolu/issues/264).
2023-01-06 16:42:22 +03:00
* The `ormolu` function now consumes `Text` instead of `String` due to an
internal refactoring.
* Exposed a more complete public API in the `Ormolu` module. The API is
supposed to be stable and change according to
[PVP](https://pvp.haskell.org/).
* Now warnings regarding Ormolu not being able to find `.cabal` files or
finding such files but them not mentioning the source file in question are
only displayed when `--debug` is used. Printing the warnings by default
seems to have been confusing, see e.g. [Issue
971](https://github.com/tweag/ormolu/issues/971) and [issue
924](https://github.com/tweag/ormolu/issues/924).
## Ormolu 0.5.2.0
* Eliminated the `fixity-th` Cabal flag because it caused issues on GHC 9.4 as
well as on aarch64. See [issue
941](https://github.com/tweag/ormolu/issues/941) and [issue
927](https://github.com/tweag/ormolu/issues/927).
2023-01-04 11:52:16 +03:00
* Now operators without explicitly specified fixity default to left
associativity and highest precedence. [Issue
907](https://github.com/tweag/ormolu/issues/907).
2022-11-14 19:30:07 +03:00
## Ormolu 0.5.1.0
* Imports are now sorted by package qualifier, if one is present.
[Issue 905](https://github.com/tweag/ormolu/issues/905).
* Extension packs like `GHC2021` and `Haskell2010` are now bumped to the top of
the list of language pragmas. [Issue
922](https://github.com/tweag/ormolu/issues/922).
* Fix formatting of `SCC` pragmas in `do` blocks. [Issue
925](https://github.com/tweag/ormolu/issues/925).
2022-11-02 17:21:08 +03:00
* Support type applications in patterns. [Issue
930](https://github.com/tweag/ormolu/issues/930).
* Handle `UnicodeSyntax` variants more consistently. [Issue
934](https://github.com/tweag/ormolu/issues/934).
* Fix an inconsistency in formatting of types in GADT declarations in
certain cases. [PR 932](https://github.com/tweag/ormolu/pull/932).
2022-08-22 20:41:08 +03:00
* Switched to `ghc-lib-parser-9.4`, which brings support for the following new
syntactic features:
* `\cases` via `LambdaCase`
* `OPAQUE` pragmas
* Unboxed sum type constructors like `(# | #)`.
* Updated to `Cabal-syntax-3.8`, supporting `cabal-version: 3.8`.
2022-08-05 17:26:26 +03:00
## Ormolu 0.5.0.1
* Fixed a bug in the diff printing functionality. [Issue
886](https://github.com/tweag/ormolu/issues/886).
* Indent closing bracket for list comprehensions in `do` blocks.
[Issue 893](https://github.com/tweag/ormolu/issues/893).
* Fix `hs-source-dirs: .` resulting in failing to find a `.cabal` file for a
Haskell source file. [Issue 909](https://github.com/tweag/ormolu/issues/909).
* Comments in closed type family declarations are now indented correctly.
[Issue 913](https://github.com/tweag/ormolu/issues/913).
* Cache `.cabal` file parsing and processing when given multiple input files in
the same project. This results in dramatic speedups on projects which have
both huge `.cabal` files and a large number of individual modules. [Issue
897](https://github.com/tweag/ormolu/issues/897).
2022-05-12 14:54:07 +03:00
## Ormolu 0.5.0.0
2021-11-29 18:42:00 +03:00
* Changed the way operator fixities and precedences are inferred.
* Ormolu now tries to locate `.cabal` files of source files by default and
in addition to default extensions it also infers the list of
dependencies.
* Ormolu comes equipped with extensive knowledge of all packages on
Hackage and operators that those packages define. Knowing the names of
the dependencies it can select the right fixity and precedence info from
its knowledge base.
* You can ask Ormolu not to look for `.cabal` files by using the
`--no-cabal` switch.
* Dependencies can be selected manually by using the `-p / --package`
option (can be repeated many times).
* The default heuristic algorithm will still try to guess the right
fixities and precedence.
* Fixity overrides can be provided by the user in the familiar Haskell
notation (e.g. `infixr 9 .`, one declaration per line). They are loaded
by default from the `.ormolu` file that is expected to be in the same
directory as the `.cabal` file of a given source file. However, if
`--no-cabal` is supplied, the `.ormolu` file will not be looked for either.
Fixity declarations can be also provided by using the `-f / --fixity`
command line option, which see.
* This resolves the following issues: [Issue
826](https://github.com/tweag/ormolu/issues/826), [Issue
785](https://github.com/tweag/ormolu/issues/785), [Issue
690](https://github.com/tweag/ormolu/issues/690), [Issue
825](https://github.com/tweag/ormolu/issues/825).
* Invalid haddock comments are formatted in a more consistent way. Leading
haddock triggers (`|`, `^`) in an invalid haddock comment block are now
escaped with a backslash `\`. [Issue
816](https://github.com/tweag/ormolu/issues/816).
* Type synonyms and families are now formatted correctly when the equals sign
is preceded by a comment. [Issue 829](
https://github.com/tweag/ormolu/issues/829).
* Bidirectional pattern synonyms are formatted nicer in certain cases.
[Issue 843](https://github.com/tweag/ormolu/issues/843).
* Magic comments (like `{- ORMOLU_DISABLED -}`) now allow arbitrary
succeeding text. This fixes use cases like [Issue
856](https://github.com/tweag/ormolu/issues/856).
* Remove discrepancies between unboxed types and terms. [Issue 856
](https://github.com/tweag/ormolu/issues/856).
* Unboxed sum types are now formatted with a space before each `|`.
* Unboxed unit tuples on type and value levels are formatted as `(# #)`.
* Errors caused by AST differences now print before/after diffs.
[Issue 877](https://github.com/tweag/ormolu/issues/877).
* Improved formatting of data declarations in the case of single-constructor
record with a Haddock. [Issue
881](https://github.com/tweag/ormolu/issues/881).
2021-11-29 14:15:54 +03:00
## Ormolu 0.4.0.0
* When a guard is located on its own line, the body associated with this
guard is indented by one extra level, so that it can easily be
distinguished from the guard predicate or pattern. [Issue
806](https://github.com/tweag/ormolu/issues/806).
* Now a space is forced after `--` in line comments. [Issue
808](https://github.com/tweag/ormolu/issues/808).
2021-10-18 17:00:46 +03:00
* Allow formatting Backpack signature files (`.hsig`). The switch between
regular module mode and signature mode is based on the file extension by
default, but can be overridden with the `-t / --source-type` command line
option. [Issue 600](https://github.com/tweag/ormolu/issues/600).
2021-10-28 00:04:13 +03:00
* Blank Haddock comments are now eliminated. This also fixes issues with
differing ASTs in some special cases. [Issue
726](https://github.com/tweag/ormolu/issues/726).
* Rewrite rules that are never active are now formatted correctly.
[Issue 823](https://github.com/tweag/ormolu/issues/823).
2021-09-20 12:04:01 +03:00
* Promoted infix data constructors are now formatted correctly. [Issue 768](
https://github.com/tweag/ormolu/issues/768).
* Switched to `ghc-lib-parser-9.2`.
[Issue 794](https://github.com/tweag/ormolu/issues/794).
* Support for the new syntax-related language extensions:
`OverloadedRecordDot` and `OverloadedRecordUpdate`
(disabled by default).
[Issue 709](https://github.com/tweag/ormolu/issues/709).
* Removed support for `record-dot-preprocessor`. For the getter syntax,
consider using `OverloadedRecordDot` instead. [Issue
659](https://github.com/tweag/ormolu/issues/659). [Issue
705](https://github.com/tweag/ormolu/issues/705).
2021-09-20 12:04:01 +03:00
* Support for the `GHC2021` language.
2021-10-14 21:22:32 +03:00
## Ormolu 0.3.1.0
* Allow check mode when working with stdin input. [Issue 634](
https://github.com/tweag/ormolu/issues/634).
* Now guards are printed on a new line if at least one guard is multiline or
if all guards together occupy more than one line. The body of each guard
is also indented one level deeper in that case. [Issue
712](https://github.com/tweag/ormolu/issues/712).
* Invalid Haddock comments are no longer silently deleted, but rather converted
into regular comments. [Issue 474](https://github.com/tweag/ormolu/issues/474).
2021-09-24 17:00:11 +03:00
## Ormolu 0.3.0.1
* Improvements to `.cabal` file handling:
* When looking for a `.cabal` file, directories were previously
erroneously also considered. [Issue 781](
https://github.com/tweag/ormolu/issues/781).
* We now print a note if Ormolu was told to consider
`.cabal` files, but no suitable one could be found.
* Handle an empty `hs-source-dirs` correctly.
* Also consider modules which are only conditionally listed
in the `.cabal` file.
* The special handling of CPP is now only applied if CPP is
actually enabled. [Issue 782](https://github.com/tweag/ormolu/issues/782).
* The left hand side of the `:` operator now uses braces if
necessary. [Issue 780](https://github.com/tweag/ormolu/issues/780).
2021-09-14 12:10:02 +03:00
## Ormolu 0.3.0.0
* Data declarations with multiline kind signatures are now formatted
correctly. [Issue 749](https://github.com/tweag/ormolu/issues/749).
* Infix arrow command formations are formatted like usual operators.
This fixes [Issue 748](https://github.com/tweag/ormolu/issues/748).
* `do` arrow commands are formatted more flexibly. Fixes [Issue
753](https://github.com/tweag/ormolu/issues/753).
2021-09-14 12:10:02 +03:00
* Source code is always read and written using UTF8 and ignoring the native
line ending conventions. [Issue
717](https://github.com/tweag/ormolu/issues/717).
* Opt-in support to respect default-extensions and default-language
from .cabal files. [Issue 517](https://github.com/tweag/ormolu/issues/517).
* Empty case expressions are now rendered with braces. [Issue
765](https://github.com/tweag/ormolu/issues/765).
* Omit braces on repeated application of `do` blocks. [Issue
735](https://github.com/tweag/ormolu/issues/735).
* Improved handling of disabled regions. [PR 773](
https://github.com/tweag/ormolu/pull/773).
* Disabled regions are now exactly preserved, in particular
empty lines and trailing spaces. [Issue
673](https://github.com/tweag/ormolu/issues/673).
* Strings like `-}` can now be present in disabled regions.
[Issue 708](https://github.com/tweag/ormolu/issues/708).
This means that using CPP or magic comments in certain ways which
were only supported as a side effect previously (like in
[Issue 601](https://github.com/tweag/ormolu/issues/601))
will now result in formatting failures. Also see [Issue 774](
https://github.com/tweag/ormolu/issues/774).
2021-08-07 19:11:08 +03:00
## Ormolu 0.2.0.0
* Now standalone kind signatures are grouped with type synonyms. [Issue
683](https://github.com/tweag/ormolu/issues/683).
2021-04-17 19:40:40 +03:00
* `TemplateHaskell` is not enabled by default anymore. [Issue
699](https://github.com/tweag/ormolu/issues/699).
* Made record dot pre-processor rendering idempotent in certain specific
cases. [Issue 701](https://github.com/tweag/ormolu/issues/701).
2021-07-03 15:13:24 +03:00
* Added support for arrow command application. [Issue
716](https://github.com/tweag/ormolu/issues/716).
* Switched to `ghc-lib-parser-9.0.1`. [PR
722](https://github.com/tweag/ormolu/pull/722).
* Support for the new language extensions:
* `LexicalNegation`, `LinearTypes`: disabled by default
* `QualifiedDo`: enabled by default
* Due to [upstream changes in whitespace sensitity](
https://gitlab.haskell.org/ghc/ghc/-/wikis/migration/9.0#whitespace-sensitive-and-),
`TypeApplications` is now *enabled* by default. [Issue
452](https://github.com/tweag/ormolu/issues/452).
* Haddocks on declarations in files without a `module` header are no longer
deleted. [Issue 480](https://github.com/tweag/ormolu/issues/480).
* Due to a change in Haddock parsing, empty Haddock comments on function
arguments now get deleted.
* CTYPE pragmas are now preserved. [Issue 689](
https://github.com/tweag/ormolu/issues/689).
* `TypeApplications` in data/type family instances are now supported. [Issue
698](https://github.com/tweag/ormolu/issues/698).
* Formatting infix arrow command formations now preserves the AST. [Issue
718](https://github.com/tweag/ormolu/issues/718).
* Surround code in brackets with spaces if it contains a `StarIsType` `*` to
prevent unparseable output. [Issue 704](https://github.com/tweag/ormolu/issues/704).
* Formatting applied multiline constructs in do blocks now preserves the AST.
[Issue 707](https://github.com/tweag/ormolu/issues/707).
This will sometimes result in odd indentations, e.g. this snippet is a
fixed point:
```haskell
foo = do
do
(+1)
1
```
* GHC options passed in via the CLI can now be overridden in local files.
Previously, if an extension was disabled via the CLI, it could not be
re-enabled per file.
2021-08-08 13:53:28 +03:00
* `NegativeLiterals` is no longer enabled by default. Also, spaces after
negation via `-` are removed where possible. [Issue
694](https://github.com/tweag/ormolu/issues/694).
* Minus signs in literal patterns are now preserved in all cases. [Issue
733](https://github.com/tweag/ormolu/issues/733).
* Added support for left-to-right arrow application. [Issue
737](https://github.com/tweag/ormolu/issues/737).
2021-08-08 13:53:28 +03:00
* Now `--mode check` fails on missing trailing blank lines. [Issue
743](https://github.com/tweag/ormolu/issues/743).
* Fixed indentation of arrow forms in do blocks. [Issue
739](https://github.com/tweag/ormolu/issues/739).
## Ormolu 0.1.4.1
* Added command line option `--color` to control how diffs are printed.
Standardized the way errors are printed.
2020-11-14 19:07:49 +03:00
## Ormolu 0.1.4.0
2020-11-10 22:51:55 +03:00
* Added support for monad comprehensions. [Issue
2020-11-15 12:40:18 +03:00
665](https://github.com/tweag/ormolu/issues/665).
2020-11-10 22:51:55 +03:00
* Fixed a bug when a space was inserted in front of promoted types even when
it wasn't strictly necessary. [Issue
2020-11-15 12:40:18 +03:00
668](https://github.com/tweag/ormolu/issues/668).
* Now the checking mode displays diffs per file when unformatted files are
found. The rendering of the diffs is also improved. [Issue
656](https://github.com/tweag/ormolu/issues/656).
## Ormolu 0.1.3.1
* Fixed a problem with multiline record updates using the record dot
preprocessor. [Issue 658](https://github.com/tweag/ormolu/issues/658).
2020-09-22 00:00:00 +03:00
## Ormolu 0.1.3.0
* Ormolu no longer overwrites already formatted files. [PR
649](https://github.com/tweag/ormolu/pull/649).
* Now a space is guaranteed before ticked promoted types. [Issue
631](https://github.com/tweag/ormolu/issues/631).
2020-09-22 00:04:25 +03:00
* Made formatting of single-line explicitly bidirectional pattern synonyms
idempotent. [Issue 630](https://github.com/tweag/ormolu/issues/630).
## Ormolu 0.1.2.0
* Fixed the bug when comments in different styles got glued together after
formatting. [Issue 589](https://github.com/tweag/ormolu/issues/589).
* Added `-i` as a shortcut for `--mode inplace`. [Issue
467](https://github.com/tweag/ormolu/issues/467).
* Improved grouping of top-level declarations. [Issue
466](https://github.com/tweag/ormolu/issues/466).
2020-06-23 12:42:57 +03:00
## Ormolu 0.1.1.0
* Imports in a import lists are now normalized: duplicate imports are
combined/eliminated intelligently.
2020-06-22 13:25:59 +03:00

566](https://github.com/tweag/ormolu/issues/566).
* Fixed an idempotence issue with inline comments in tuples and parentheses.
[Issue 450](https://github.com/tweag/ormolu/issues/450).
2020-05-25 22:03:53 +03:00

“continuation” of a series of comments [Issue
449](https://github.com/tweag/ormolu/issues/449).
* Fixed an idempotence issue related to different indentation levels in a

multiple blank lines in a row. [Issue
518](https://github.com/tweag/ormolu/issues/518).
2020-05-25 22:03:53 +03:00
* Fixed rendering of comments around if expressions. [Issue
458](https://github.com/tweag/ormolu/issues/458).
* Unnamed fields of data constructors are now documented using the `-- ^`
syntax. [Issue 445](https://github.com/tweag/ormolu/issues/445) and [Issue

## Ormolu 0.0.5.0
2020-04-16 14:40:13 +03:00
* Grouping of statements in `do`-blocks is now preserved. [Issue
2020-04-16 14:40:13 +03:00
74](https://github.com/tweag/ormolu/issues/74).
* Grouping of TH splices is now preserved. [Issue
507](https://github.com/tweag/ormolu/issues/507).
2020-04-17 13:20:00 +03:00
* Comments on pragmas are now preserved. [Issue
216](https://github.com/tweag/ormolu/issues/216).
* Ormolu can now be enabled and disabled via special comments. [Issue
435](https://github.com/tweag/ormolu/issues/435).
2020-04-21 15:36:56 +03:00
* Added experimental support for simple CPP. [Issue
415](https://github.com/tweag/ormolu/issues/415).
2020-04-23 19:41:32 +03:00
* Added two new options `--start-line` and `--end-line` that allow us to
select a region to format. [Issue
516](https://github.com/tweag/ormolu/issues/516).
2020-04-24 20:43:45 +03:00
* Fixed rendering of module headers in the presence of preceding comments or
Haddocks. [Issue 561](https://github.com/tweag/ormolu/issues/561).
2020-04-15 16:52:50 +03:00
## Ormolu 0.0.4.0
* When given several files to format, Ormolu does not stop on the first
failure, but tries to format all the files. [Issue
502](https://github.com/tweag/ormolu/issues/502).
* Made rendering of pattern matches involving operators consistent with
other cases of rendering of operators. [Issue
500](https://github.com/tweag/ormolu/issues/500).
* More compact rendering of type family injectivity constraints. [Issue
482](https://github.com/tweag/ormolu/issues/482).
* Improved rendering of the keyword `where` in class, data, and type family
declarations. When headers of these declarations are multi-line `where` is
now put on its own line. [Issue
509](https://github.com/tweag/ormolu/issues/509).
* Fixed the bug pertaining to rendering of arrow notation with multiline
expressions. [Issue 513](https://github.com/tweag/ormolu/issues/513).
* Made rendering of data type definitions, value-level applications, and
application of types use the same style. Moreover, existential now doesn't
cause the data constructor be unconditionally rendered in multiline
layout. [Issue 427](https://github.com/tweag/ormolu/issues/427).
* Records with a single data constructor are now formatted more compactly.
[Issue 425](https://github.com/tweag/ormolu/issues/425).
* Switched to `ghc-lib-parser-8.10.1`.
* Implemented support for the new language extensions `ImportQualifiedPost`
and `StandaloneKindSignatures`.
2020-01-22 21:17:34 +03:00
## Ormolu 0.0.3.1
* Fixed rendering of record updates with the record dot preprocessor syntax
[Issue 498](https://github.com/tweag/ormolu/issues/498).
2020-01-11 15:06:12 +03:00
## Ormolu 0.0.3.0
* Fixed an issue related to unnecessary use of curly braces. [Issue
473](https://github.com/tweag/ormolu/issues/473).
* Fixed the issue with formatting multi-way if when it happens to be a
function applied to arguments [Issue
488](https://github.com/tweag/ormolu/issues/488). This changed the way
multi-line if is formatted in general.
* Added support for record dot pre-processor when used via the plugin.
[Issue 486](https://github.com/tweag/ormolu/issues/486).
* Stopped hanging record constructors and improved placing
potentially-hanging consturctions in the presence of comments. [Issue
447](https://github.com/tweag/ormolu/issues/447).
* Fixed indentation in presence of type applications. [Issue
493](https://github.com/tweag/ormolu/issues/493).
* Class and instance declarations now do not have a blank line after
`where`. Grouping of methods from the original input is also preserved
with some normalizations. [Issue
431](https://github.com/tweag/ormolu/issues/431).
2019-11-29 19:40:05 +03:00
## Ormolu 0.0.2.0
* Switched to `ghc-lib-parser` instead of depending on the `ghc` package
directly. This should allow us to use newest features of GHC while not
necessarily depending on the newest version of the compiler. In addition
to that Ormolu is now GHCJS-compatible.
* Now unrecognized GHC options passed with `--ghc-opt` cause Ormolu to fail
(exit code 7).
* Fixed formatting of result type in closed type families. See [issue
420](https://github.com/tweag/ormolu/issues/420).
* Fixed a minor inconsistency between formatting of normal and foreign type
signatures. See [issue 408](https://github.com/tweag/ormolu/issues/408).
* Fixed a bug when comment before module header with Haddock was moved
inside the export list. See [issue
430](https://github.com/tweag/ormolu/issues/430).
2019-11-02 16:57:56 +03:00
* Empty `forall`s are now correctly preserved. See [issue
429](https://github.com/tweag/ormolu/issues/429).
2019-11-17 14:21:52 +03:00
* Fixed [issue 446](https://github.com/tweag/ormolu/issues/446), which
involved braces and operators.
* When there are comments between preceding Haddock (pipe-style) and its
corresponding declaration they are preserved like this in the output
instead of being shifted. To be clear, this is not a very good idea to
have comments in that position because the Haddock will end up not being
associated with the declarations. Issues
[440](https://github.com/tweag/ormolu/issues/440) and
[448](https://github.com/tweag/ormolu/issues/448).
* Implemented correct handling of shebangs. [Issue
377](https://github.com/tweag/ormolu/issues/377).
* Implemented correct handling of stack headers. [Issue
393](https://github.com/tweag/ormolu/issues/393).
* Sorting language pragmas cannot not change meaning of the input program
anymore. [Issue 404](https://github.com/tweag/ormolu/issues/404).
* Fixed formatting of applications where function is a complex expression.
[Issue 444](https://github.com/tweag/ormolu/issues/444).
2018-11-25 16:34:28 +03:00
## Ormolu 0.0.1.0
* Initial release.
