Decompile all the things!

IDA Batch Decompile is a plugin for Hex-Ray's IDA Pro that adds the ability to batch decompile multiple files and their imports with additional annotations (xref, stack var size) to the pseudocode .c file

idabatchdecompile

🐤 pssst! - ida-batch_decompile is also part of project: unbox - a nobrainer commandline tool to unpack and decompile all sorts of things.

Usage

idascript (gui mode)

  1. open target, wait for analysis to finish
  2. IDA Pro -> File/Script file... -> <this_python_script>
  3. IDA Pro -> File/Produce file-> IdaDecompileBatch ...
  4. tick Annotate StackVarSize, Annotate Func XRefs
  5. click OK to decompile.

Note: File will be saved in target folder as <target_image_name.c>

idascript (cmdline batch mode)

<path_to_ida>/ida(w|w64)(.exe) -B -M -S"<path_to_this_script> \"--option1\" \"--option2\"" "<target>"

Note that options need to be quoted with \"

Available options, see --help
