关于改进IntelliJ及Android Studio中Annotate（Git Blame）功能的技术咨询

Great question! Let’s walk through your three questions with practical, actionable details tailored to your goal of hiding "Reformat" and similar low-value commits from the Annotate view:

1. Can this improvement be implemented? #

Absolutely—you have two solid, feasible paths to achieve this:

• Git-native approach (no coding required): Use Git’s built-in --ignore-revs-file feature to tell Git (and by extension, your IDE) to skip specific commits during blame operations. This works directly with the IDE’s existing Annotate tool without needing plugins or core file modifications.
• Custom IntelliJ Plugin: If you want dynamic, rule-based filtering (like auto-hiding any commit with "Reformat" in the message without manually listing hashes), you can build a plugin using the IntelliJ Platform SDK. This lets you extend the Annotate functionality to automatically exclude commits matching your criteria.

2. Will this work with Android Studio? #

Yes, full compatibility is guaranteed! Android Studio is built on the IntelliJ Platform, so:

• The Git-native approach works exactly the same as in IntelliJ IDEA—just configure the ignore file in Android Studio’s Git settings.
• For plugins, you only need to target the specific IntelliJ Platform version that your Android Studio release is based on (e.g., Android Studio Hedgehog uses IntelliJ 2023.1). You can find this version in Android Studio’s Help > About dialog.

3. Getting started with implementation #

Option 1: Git-native ignore (quickest setup) #

• Create a file named .git-blame-ignore-revs in your repository root.
• Add the full commit hash of each "Reformat" or non-critical commit you want to hide, one per line.
• In Android Studio/IntelliJ, go to Settings > Version Control > Git, check the box for Ignore revisions file, and select your .git-blame-ignore-revs file.
• Restart the Annotate view—those commits will now be skipped, showing the last meaningful commit instead.

Option 2: Build a custom plugin (for dynamic filtering) #

• Learn the basics first: Familiarize yourself with the IntelliJ Platform Plugin SDK, focusing on VCS-related APIs. Key classes to explore include BlameManager, AnnotateLineProvider, and Commit.
• Set up your project: Use the IntelliJ Plugin DevKit to create a new plugin project, and select the IntelliJ Platform version matching your Android Studio release.
• Implement the filter logic: Write code that intercepts the Annotate data, checks each commit’s message for keywords like "Reformat", and excludes those commits from the displayed blame results.
• Test and iterate: Use the plugin run configuration to launch a test instance of Android Studio, install your plugin, and verify that the Annotate view filters out the targeted commits.
• Package and deploy: Once tested, package the plugin as a .jar or .zip file and install it directly in your Android Studio via Settings > Plugins > Install Plugin from Disk.
