Configuration

The decompiler has a configuration file. It is installed into the 'cfg' subdirectory of the IDA installation. The configuration file is named 'hexrays.cfg'. It is a simple text file, which can be edited to your taste. Currently the following keywords are defined:

  • LOCTYPE_BGCOLOR
    Background color of local type declarations. Currently this color is not used.
    Default: default background of the disassembly view
  • VARDECL_BGCOLOR
    Background color of local variable declarations. It is specified as a hexadecimal number 0xBBGGRR where BB is the blue component, GG is the green component, and RR is the red component. Color -1 means the default background color (usually white).
    Default: default background of the disassembly view
  • FUNCBODY_BGCOLOR
    Background color of the function body. It is specified the same way as VARDECL_BGCOLOR.
    Default: default background of the disassembly view
  • BLOCK_INDENT
    Number of spaces to use for block indentations.
    Default: 2
  • COMMENT_INDENT
    The position to start indented comments.
    Default: 48
  • RIGHT_MARGIN
    As soon as the line length approaches this value, the decompiler will try to split it. However, it some cases the line may be longer.
    Default: 120
  • HEXOPTIONS
    Combination of various analysis and display options:

    • HO_JUMPOUT_HELPERS
      If enabled, the decompiler will handle out-of-function jumps by generating a call to the JUMPOUT() function. If disables, such functions will not be decompiled.
      Default: enabled
    • HO_DISPLAY_CASTS
      If enabled, the decompiler will display cast operators in the output listing.
      Default: enabled
    • HO_HIDE_UNORDERED
      If enabled, the decompiler will hide unordered floating point comparisons. If this option is turned off, unordered comparisons will be displayed as calls to a helper function: __UNORDERED__(a, b)
      Default: enabled
    • HO_SSE_INTRINSICS
      If enabled, the decompiler will generate intrinsic functions for SSE instructions that use XMM/MMX registers. If this option is turned off, these instructions will be displayed using inline assembly.
      Default: enabled

  • WARNS1
    Specifies the warning messages that should be displayed after decompilation. Please refer to hexrays.cfg file for the details.
    Default: all warnings are on
