Hex Ray has introduced a decompiler API as part of IDA v6.6. Is there any plugin which displays the detail Abstract Syntax Tree (AST) produced by the decompiler graphically?

I want something like this as mentioned in this post. Unfortunately, I can't find the Display graph option in IDA v6.95

  • My browser doesn't like Flash :) Can you make a screenshot and include it in your post?

See the vds5 plugin in the Hex-Rays SDK.

 *      Hex-Rays Decompiler project
 *      Copyright (c) 2007-2008 by Hex-Rays, [email protected]
 *      Sample plugin for the Hex-Rays Decompiler.
 *      It adds a new command to show graph of the ctree.
 *      The current item will be highlighted in the graph.
 *      The command hotkey is G. It is also added into the right-click menu.
 *      To display the graph, we traverse the ctree and build
 *      a gdl_graph_t object. Then we use gen_gdl() function from IDA
 *      to create a GDL file from this object. Finally, we call
 *      wingraph32 to display the graph on the screen.
  • Python version of vds5 is not available for IDA v6.95 github.com/idapython/src/tree/master/examples

  • Since I am using IDA v6.95, I can't use vds5 unfortunately. BTW, to use CPP version of the same, I need IDA SDK to compile it. Right?

  • I'm pretty sure the Hex-Rays SDK in 6.95 includes vds5 (native version). If not, you should contact support.

  • I just checked IDA SDK 6.95, couldn't find vds5. Where should it be located? I'll check one final time before reaching out support.
