File contents

JetBrains Theme Investigation

Investigate theme properties in the IntelliJ Platform source code to determine what is themeable via JSON vs hardcoded in source.

Prerequisites

IntelliJ Platform source code must be available at:

../../JetBrains/intellij-community

(Relative to current project directory)

If not cloned yet:

cd ~/Projects/github.com/JetBrains
git clone https://github.com/JetBrains/intellij-community

Quick Investigation Workflow

Search theme metadata first (what properties exist):

grep -i "PropertyName" ../../JetBrains/intellij-community/platform/platform-resources/src/themes/metadata/*.json

Check reference themes (how properties are used):

grep -r "PropertyName" ../../JetBrains/intellij-community/platform/platform-resources/src/themes/ --include="*.json"

Search JBUI.java for programmatic color access:

grep -A3 "namedColor.*PropertyName" ../../JetBrains/intellij-community/platform/util/ui/src/com/intellij/util/ui/JBUI.java

Search source for hardcoded values if not found above:

grep -rn "propertyName\|PROPERTY_NAME" ../../JetBrains/intellij-community/platform/platform-*/src --include="*.kt" --include="*.java"

Key Directories

Path	Content
`platform/platform-resources/src/themes/metadata/`	Available theme properties (IntelliJPlatform.themeMetadata.json, JDK.themeMetadata.json)
`platform/platform-resources/src/themes/`	Reference themes (expUI, islands, darcula, HighContrast)
`platform/util/ui/src/com/intellij/util/ui/JBUI.java`	CurrentTheme methods mapping to JSON keys
`platform/icons/src/`	SVG icons (check colors used)

Detailed References

For specific subsystems, see:

Icon colors: icon-colors.md - ColorPalette, stroke colors, named keys
Tab system: tab-system.md - Tab gaps, insets, layouts
Islands theme: islands-theme.md - Islands-specific properties
Known limitations: limitations.md - What is NOT themeable
Theme testing panel: theme-testing-panel.md - Dev-mode UI testing panel

Determining if Themeable

Found In	Result
Theme metadata JSON	Themeable via JSON
JBUI.java with `namedColor`/`getInt`	Themeable via JSON
Source code with hardcoded values	NOT themeable (requires code change)
