xray is a plugin for the Hexrays decompiler that uses regular expressions in order to highlight points-of-interest of decompiled functions.

xray installs itself as a plugin by loading it as a script using the "File->Script file..." (Alt-F7) menu item within IDA.

Running the plugin for the first time creates a default configuration file (%APPDATA%Hex-Rays/IDA Pro/plugins/xray.cfg) which can and should be customized by the user.

IDA 7.2+ required.

The plugin attempts to match regular expressions taken from its configuration file with each of the decompiler's text lines. Successful matches will cause the background color of a matching text line to be changed, whereas any non-matching lines will have their colors removed entirely, thereby causing an "xray" effect.

This will help isolate relevant spots when browsing through large decompiled functions.

Regular expressions as well as the background color should be customized according to personal requirements.

• F3: Toggle xray
• Ctrl-R: Reload configuration (edit the configuration file on-the-fly and add new regular expressions or change the default background color)
