Hex-Rays Block Highlighter - Highlight blocks in IDA Pseudocode windows

Overview

Hex-Rays Block Highlighter is an IDA Pro plugin to highlight code blocks in the Hex-Rays decompiler output.

In some cases the decompilation output can be quite hairy with lots of nested blocks and it can be hard to follow where one ends and the other begins. This plugin will highlight blocks in a sticky way, allowing one to navigate within the window while keeping the block highlight around.

Installation

Hex-Rays Block Highlighter is an IDAPython plugin with no external dependencies. As such, it should work on all platforms supported by IDA.

Method 1: copying files

Copy the contents of the plugins directory into your IDA plugins directory and restart IDA.

Method 2: the IDAUSR variable

You could add an entry to your IDAUSR environment variables pointing to the root directory of this project.

Example:

1. cd /Users/bob/tmp
2. git clone https://github.com/vmallet/ida-hex-highlighter.git
3. ADD /Users/bob/tmp/ida-hex-highlighter to your IDAUSR environment variable, and restart IDA

Usage

In a Pseudocode window:

• Double-click on a do, for, if, switch, or while keyword to highlight the corresponding block (or blocks in the if and switch cases).
• Double-click the same keyword to turn the highlighting off
• With the keyboard, navigate to a keyword and press Shift-H to toggle the highlighting on/off
• You can also Right-Click and choose "Highlight Block (toggle)
