Check if ktlint_code_style is set in .editorconfig before overriding it by OlivierGenez · Pull Request #2143 · diffplug/spotless

OlivierGenez · 2024-05-28T00:56:47Z

ktlint_code_style gets unconditionally overridden to its default value (intellij_idea) when the editorConfigOverride map is non-empty but does not define it. As a result, it gets overridden even if it's actually defined in the .editorconfig file.

This change checks if ktlint_code_style is already defined in .editorconfig before overriding it to its default value.

Fixes #2142.

Thanks for the quick reply!

The PR already has this test: https://github.com/diffplug/spotless/pull/2143/files#diff-7bbe43d03149d8aad5b95564d57dc5bf59cba4ce539a44e01bbe51215dcdae71R131-R147. Is it sufficient, or is there a specific/additional scenario I am missing that you're after?

Ooooops, will take a look later.

The key point is here, I missed checking EditorConfig file properties in #1808.

Nice, can you add a test case like 87537c0 for maven as well?

Done!

While adding the test I realised that plugin-maven never defaulted EditorConfig's path to .editorconfig, so I fixed that too.

The default path was never set, which means that .editorconfig was never picked up if not explicitly set.

This verifies that the previous fix which checks if ktlint_code_style is already defined in .editorconfig before overriding it works as expected in plugin-maven.

Will load EMPTY_EDITOR_CONFIG_DEFAULTS before

spotless/lib/src/compatKtLint1Dot0Dot0/java/com/diffplug/spotless/glue/ktlint/compat/KtLintCompat1Dot0Dot0Adapter.java

Lines 96 to 101 in cf6c76f

EditorConfigDefaults editorConfig;

if (editorConfigPath == null || !Files.exists(editorConfigPath)) {

editorConfig = EditorConfigDefaults.Companion.getEMPTY_EDITOR_CONFIG_DEFAULTS();

} else {

editorConfig = EditorConfigDefaults.Companion.load(editorConfigPath, RuleProviderKt.propertyTypes(allRuleProviders));

}

But this should parse the root .editorconfig, I forget the exact position, let me check.

You are right! KtLintRuleEngine will load the .editorconfig.

However I believe we still need to load it ourselves as well in order to check if it sets ktlint_code_style in KtLintCompat1Dot0Dot0Adapter. Otherwise we will run into the original issue: ktlint_code_style will be overridden to its default value (intellij_idea) when the editorConfigOverride map is non-empty but does not define it. This is also what plugin-gradle does:

spotless/plugin-gradle/src/main/java/com/diffplug/gradle/spotless/BaseKotlinExtension.java

Lines 159 to 160 in add4c1e

File defaultEditorConfig = getProject().getRootProject().file(".editorconfig");

FileSignature editorConfigPath = defaultEditorConfig.exists() ? FileSignature.signAsList(defaultEditorConfig) : null;

Suggested change

if (editorConfigPath == null) {

File defaultEditorConfig = new File(".editorconfig");

if (defaultEditorConfig.exists()) {

editorConfigPath = defaultEditorConfig.getPath();

}

}

if (editorConfigPath == null && defaultEditorConfig.exists()) {

editorConfigPath = defaultEditorConfig.getPath();

}

And add

private static final File defaultEditorConfig = new File(".editorconfig");

Quick shot!
