Converts asm to pseudo-C code.

Software Requirements

Requires rizin.

Install in home folder (or in other paths)

If you want to install in the HOME folder or in other non standard paths, just set the prefix to a different value

Run meson setup build --prefix=~/.local
Run ninja -C build install

Install system wide

Follow the following steps to install jsdec

clone this repository
Run meson setup build --prefix=/usr to create the build folder
Run ninja -C build install to build the shared library and to install it

Usage

Open your file with rizin
Analyze the function you want to disassemble (af)
Run the plugin via pdd

Arguments

[0x00000000]> pdd?
Usage: pdd[?]   # Core plugin for jsdec
| pdd  # decompile current function
| pddt # lists the supported architectures
| pdda # decompile current function with side assembly
| pddA # decompile current function with annotation output
| pddb # decompile current function but show only scopes
| pddc # decompiled code is returned to rizin as 'file:line code' (via CL)
| pddf # decompile all functions
| pddi # generate issue data
| pddj # decompile current function as json
| pddo # decompile current function side by side with offsets

Evaluable vars

You can use these in your .rizinrc file.

jsdec.asm           | if true, shows pseudo next to the assembly.
jsdec.blocks        | if true, shows only scopes blocks.
jsdec.casts         | if false, hides all casts in the pseudo code.
jsdec.debug         | do not catch exceptions in jsdec.
jsdec.paddr         | if true, all xrefs uses physical addresses compare.
jsdec.slow          | if true load all the data before to avoid multirequests to rizin.
jsdec.xrefs         | if true, shows all xrefs in the pseudo code.
e scr.html          | outputs html data instead of text.
e scr.color         | enables syntax colors.

Report an Issue

Open your file with rizin
Analyze the function you want to disassemble (af)
Give the data to the plugin via pddi or pdd --issue
Insert the JSON returned by the previous command into the issue (you can also upload the output)
