Decompile all the things! (Work in progress)

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

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
