v0.48.0

Compare Source

Indent rule

The indent rule has been rewritten from scratch. Solving problems in the old algorithm was very difficult. With the new algorithm this becomes a lot easier. Although the new implementation of the rule has been compared against several open source projects containing over 400,000 lines of code, it is still likely that new issues will be discovered. Please report your indentation issues so that these can be fixed as well.

.editorconfig property to disable rules

In the previous release (0.47.x), the .editorconfig property disabled_rules was deprecated and replaced with ktlint_disabled_rules. This latter property has now been deprecated as well in favour of a more flexible and better maintainable solution. Rule and rule sets can now be enabled/disabled with a separate property per rule (set). Please read deprecation of (ktlint_)disable_rules property for more information.

The KtLint CLI has not been changed. Although you can still use parameter --experimental to enable KtLint's Experimental rule set, you might want to set .editorconfig property ktlint_experimental = enabled instead.

API Changes & RuleSet providers

If you are not an API consumer or Rule Set provider then you can skip this section.

Class relocations

Classes below have been relocated:

• Class com.pinterest.ktlint.core.api.UsesEditorConfigProperties.EditorConfigProperty has been replaced with com.pinterest.ktlint.core.api.editorconfig.EditorConfigProperty.
• Class com.pinterest.ktlint.core.KtLintParseException has been replaced with com.pinterest.ktlint.core.api.KtLintParseException.
• Class com.pinterest.ktlint.core.RuleExecutionException has been replaced with com.pinterest.ktlint.core.api.KtLintRuleException.
• Class com.pinterest.ktlint.reporter.format.internal.Color has been moved to com.pinterest.ktlint.reporter.format.Color.
• Class com.pinterest.ktlint.reporter.plain.internal.Color has been moved to com.pinterest.ktlint.reporter.plain.Color.

Invoking lint and format

This is the last release that supports the ExperimentalParams to invoke the lint and format functions of KtLint. The ExperimentalParams contains a mix of configuration settings which are not dependent on the file/code which is to be processed. Other parameters in that class describe the code/file to be processed but can be configured inconsistently (for example a file with name "foo.kt" could be marked as a Kotlin Script file).

The static object KtLint is deprecated and replaced by class KtLintRuleEngine which is configured with KtLintRuleEngineConfiguration. The instance of the KtLintRuleEngine is intended to be reused for scanning all files in a project and should not be recreated per file.

Both lint and format are simplified and can now be called for a code block or for an entire file.

import java.io.File

// Define a reusable instance of the KtLint Rule Engine
val ktLintRuleEngine = KtLintRuleEngine(
  // Define configuration
)

// Process a collection of files
val files: Set<File> // Collect files in a convenient way
files.forEach(file in files) {
    ktLintRuleEngine.lint(file) {
        // Handle lint violations
    }
}

// or process a code sample for a given filepath
ktLintRuleEngine.lint(
  code = "code to be linted",
  filePath = Path("/path/to/source/file")
) {
  // Handle lint violations
}

Retrieve .editorconfigs

The list of .editorconfig files which will be accessed by KtLint when linting or formatting a given path can now be retrieved with the new API KtLint.editorConfigFilePaths(path: Path): List<Path>.

This API can be called with either a file or a directory. It's intended usage is that it is called once with the root directory of a project before actually linting or formatting files of that project. When called with a directory path, all .editorconfig files in the directory or any of its subdirectories (except hidden directories) are returned. In case the given directory does not contain an .editorconfig file or if it does not contain the root=true setting, the parent directories are scanned as well until a root .editorconfig file is found.

Calling this API with a file path results in the .editorconfig files that will be accessed when processing that specific file. In case the directory in which the file resides does not contain an .editorconfig file or if it does not contain the root=true setting, the parent directories are scanned until a root .editorconfig file is found.

Psi filename replaces FILE_PATH_USER_DATA_KEY

Constant KtLint.FILE_PATH_USER_DATA_KEY is deprecated and will be removed in KtLint version 0.49.0. The file name will be passed correctly to the node with element type FILE and can be retrieved as follows:

if (node.isRoot()) {
    val fileName = (node.psi as? KtFile)?.name
    ...
}

Added

• Wrap blocks in case the max line length is exceeded or in case the block contains a new line wrapping (#​1643)
• patterns can be read in from stdin with the --patterns-from-stdin command line options/flags (#​1606)
• Add basic formatting for context receiver in indent rule and new experimental rule context-receiver-wrapping (#​1672)
• Add naming rules for classes and objects (class-naming), functions (function-naming) and properties (property-naming) (#​44)
• Add new built-in reporter plain-summary which prints a summary the number of violation which have been autocorrected or could not be autocorrected, both split by rule.

Fixed

• Let a rule process all nodes even in case the rule is suppressed for a node so that the rule can update the internal state (#​1644)
• Read .editorconfig when running CLI with options --stdin and --editorconfig (#​1651)
• Do not add a trailing comma in case a multiline function call argument is found but no newline between the arguments trailing-comma-on-call-site (#​1642)
• Add missing ktlint_disabled_rules to exposed editorConfigProperties (#​1671)
• Do not add a second trailing comma, if the original trailing comma is followed by a KDOC trailing-comma-on-declaration-site and trailing-comma-on-call-site (#​1676)
• A function signature preceded by an annotation array should be handled similar as function preceded by a singular annotation function-signature (#​1690)
• Fix offset of annotation violations
• Fix line offset when blank line found between class and primary constructor
• Remove needless blank line between class followed by EOL, and primary constructor
• Fix offset of unexpected linebreak before assignment
• Remove whitespace before redundant semicolon if the semicolon is followed by whitespace

Changed

• Update Kotlin development version to 1.8.0-RC and Kotlin version to 1.7.21.
• The default value for trailing comma's on call site is changed to true unless the android codestyle is enabled. Note that KtLint from a consistency viewpoint enforces the trailing comma on call site while default IntelliJ IDEA formatting only allows the trailing comma but leaves it up to the developer's discretion. (#​1670)
• The default value for trailing comma's on declaration site is changed to true unless the android codestyle is enabled. Note that KtLint from a consistency viewpoint enforces the trailing comma on declaration site while default IntelliJ IDEA formatting only allows the trailing comma but leaves it up to the developer's discretion. (#​1669)
• CLI options --debug, --trace, --verbose and -v are replaced with --log-level=<level> or the short version `-l=, see CLI log-level. (#​1632)
• In CLI, disable logging entirely by setting --log-level=none or -l=none (#​1652)
• Rewrite indent rule. Solving problems in the old algorithm was very difficult. With the new algorithm this becomes a lot easier. Although the new implementation of the rule has been compared against several open source projects containing over 400,000 lines of code, it is still likely that new issues will be discovered. Please report your indentation issues so that these can be fixed as well. (#​1682, #​1321, #​1200, #​1562, #​1563, #​1639)
• Add methods "ASTNode.upsertWhitespaceBeforeMe" and "ASTNode.upsertWhitespaceAfterMe" as replacements for "LeafElement.upsertWhitespaceBeforeMe" and "LeafElement.upsertWhitespaceAfterMe". The new methods are more versatile and allow code to be written more readable in most places. (#​1687)

• Add support for running tests on java 19, remove support for running tests on java 18.
• Update io.github.detekt.sarif4k:sarif4k version to 0.2.0 (#​1701).
