From acc181f2272ecfe55ab2ac66d9e5ecb7639aeb17 Mon Sep 17 00:00:00 2001 From: Paul Dingemans Date: Sat, 4 Sep 2021 17:00:56 +0200 Subject: [PATCH 1/9] Extract VisitorProvider from Ktlint class The visitor is created once for each file that has to be linted/formatted. It is now divided into two distinct phases. The setup phase is executed whenever the VisitorProvider is created. This provider is created only once per invocation of the KtLint command. In the setup phase, the rules are analysed and the order in which they have to be executed is determined. This order is identical for all nodes. As the phase is executed only once, it can now containing logging about the order in which the rules are executed. Also it opens up possibilities for more complex ordering rules using annotations and reflection (for example executing a rule after a specific rule). The visitor creation phase actually creates the visitor. In this phase all enabled rules will be executed. Note that disabling of rules depends on the '.editorconfig' which is active for a given rootNode. --- .../com/pinterest/ktlint/core/KtLint.kt | 211 ++++++++---------- .../pinterest/ktlint/core/VisitorProvider.kt | 154 +++++++++++++ .../ruleset/standard/IndentationRule.kt | 1 + .../main/kotlin/com/pinterest/ktlint/Main.kt | 59 +++-- .../pinterest/ktlint/internal/FileUtils.kt | 40 ++-- .../GenerateEditorConfigSubCommand.kt | 2 +- .../ktlint/internal/PrintASTSubCommand.kt | 18 +- 7 files changed, 328 insertions(+), 157 deletions(-) create mode 100644 ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/VisitorProvider.kt diff --git a/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/KtLint.kt b/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/KtLint.kt index 0a47bfc8a9..a8b905770c 100644 --- a/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/KtLint.kt +++ b/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/KtLint.kt @@ -3,7 +3,6 @@ package com.pinterest.ktlint.core import com.pinterest.ktlint.core.api.EditorConfigProperties import com.pinterest.ktlint.core.api.FeatureInAlphaState import com.pinterest.ktlint.core.api.UsesEditorConfigProperties -import com.pinterest.ktlint.core.ast.visit import com.pinterest.ktlint.core.internal.EditorConfigGenerator import com.pinterest.ktlint.core.internal.EditorConfigLoader import com.pinterest.ktlint.core.internal.EditorConfigLoader.Companion.convertToRawValues @@ -133,9 +132,18 @@ public object KtLint { * @throws ParseException if text is not a valid Kotlin code * @throws RuleExecutionException in case of internal failure caused by a bug in rule implementation */ + // TODO: Shouldn't this method be moved to module ktlint-test as it is called from unit tests only?

Ordering rules by rule set however is important within the scope of the VisitorProvider though. Also add order that experimental rules takes precedence over custom rules. Finally add secondary sorting on ruleId so that the order of the rules as defined by the RuleSetProviders is not relevant anymore. --- .../pinterest/ktlint/core/VisitorProvider.kt | 59 +++++++++++-------- .../ktlint/internal/RuleSetsLoader.kt | 8 +-- 2 files changed, 38 insertions(+), 29 deletions(-) diff --git a/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/VisitorProvider.kt b/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/VisitorProvider.kt index f657dbadd0..3abb0d1152 100644 --- a/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/VisitorProvider.kt +++ b/ktlint-core/src/main/kotlin/com/pinterest/ktlint/core/VisitorProvider.kt @@ -14,36 +14,49 @@ public class VisitorProvider( ) { private val ruleReferences: List = ruleSets - .flatMap { ruleSet -> - ruleSet - .rules - .map { rule -> - RuleReference( - ruleId = rule.id, - ruleSetId = ruleSet.id, - ruleReferenceGroup = rule.toRuleReferenceGroup() - ) + .flatMap { it.toRuleReferences() } + .sortedWith( + // The order of the rule sets loaded and the order of the rules inside the rule sets is replaced with + // a custom order which so that each invocation of KtLint uses the exact same rule ordering. + compareBy { + when (it.ruleSetId) { + "standard" -> 0 + "experimental" -> 1 + else -> 2 } - }.also { + }.thenBy { it.ruleId } + ) + .also { if (debug) { - println("[DEBUG]Rules will be executed in order below:") - println(" - Rules with Rule.Modifier.RestrictToRoot: ${it.print(RESTRICT_TO_ROOT)}") - println(" - Rules without Rule.Modifier: ${it.print(NORMAL)}") - println(" - Rules with Rule.Modifier.RestrictToRootLast: ${it.print(RESTRICT_TO_ROOT_LAST)}") - println(" - Rules with Rule.Modifier.Last: ${it.print(LAST)}") + println("[DEBUG] Rules will be executed in order below:") + println(" - Rules with Rule.Modifier.RestrictToRoot: ${it.print(RESTRICT_TO_ROOT)}") + println(" - Rules without Rule.Modifier: ${it.print(NORMAL)}") + println(" - Rules with Rule.Modifier.RestrictToRootLast: ${it.print(RESTRICT_TO_ROOT_LAST)}") + println(" - Rules with Rule.Modifier.Last: ${it.print(LAST)}") } } + private fun RuleSet.toRuleReferences() = + rules.map { it.toRuleReference(id) } + + private fun Rule.toRuleReference(ruleSetId: String) = + RuleReference( + ruleId = id, + ruleSetId = ruleSetId, + ruleReferenceGroup = toRuleReferenceGroup() + ) + + private fun Rule.toRuleReferenceGroup(): RuleReferenceGroup = + when (this) { + is Rule.Modifier.Last -> LAST + is Rule.Modifier.RestrictToRootLast -> RESTRICT_TO_ROOT_LAST + is Rule.Modifier.RestrictToRoot -> RESTRICT_TO_ROOT + else -> NORMAL + } + private fun List.print(ruleReferenceGroup: RuleReferenceGroup): String = filter { it.ruleReferenceGroup == ruleReferenceGroup } - .joinToString { "\n - ${it.ruleSetId}:${it.ruleId}" } - - private fun Rule.toRuleReferenceGroup() = when (this) { - is Rule.Modifier.Last -> LAST - is Rule.Modifier.RestrictToRootLast -> RESTRICT_TO_ROOT_LAST - is Rule.Modifier.RestrictToRoot -> RESTRICT_TO_ROOT - else -> NORMAL - } + .joinToString { "\n - ${it.ruleSetId}:${it.ruleId}" } internal fun visitor( ruleSets: Iterable, diff --git a/ktlint/src/main/kotlin/com/pinterest/ktlint/internal/RuleSetsLoader.kt b/ktlint/src/main/kotlin/com/pinterest/ktlint/internal/RuleSetsLoader.kt index 7768d2d39c..d24d442173 100644 --- a/ktlint/src/main/kotlin/com/pinterest/ktlint/internal/RuleSetsLoader.kt +++ b/ktlint/src/main/kotlin/com/pinterest/ktlint/internal/RuleSetsLoader.kt @@ -18,13 +18,9 @@ internal fun JarFiles.loadRulesets( RuleSetProvider::class.java, URLClassLoader(toFilesURIList().toTypedArray()) ) - .associateBy { - val key = it.get().id - // standard should go first - if (key == "standard") "\u0000$key" else key - } + .associateBy { it.get().id } .filterKeys { loadExperimental || it != "experimental" } - .filterKeys { !(disabledRules.isStandardRuleSetDisabled() && it == "\u0000standard") } + .filterKeys { !(disabledRules.isStandardRuleSetDisabled() && it == "standard") } .toSortedMap() .also { if (debug) { From 910aede1db1b3d149b482ab345e30354472a95ae Mon Sep 17 00:00:00 2001 From: Paul Dingemans Date: Tue, 7 Sep 2021 09:56:19 +0200 Subject: [PATCH 4/9] Restrict usage of Rule.Modifier to initialisation phase in which the order of the rules is determined Rule.Modifier is no longer used during actual creation of the visitor.
