In Progress OpenEdge (formerly Progress 4GL), .r files are runnable bytecode produced by compiling .p (procedure) or .w (window) source files. They contain p-codes interpreted by the OpenEdge runtime engine.

对于任何R函数（包括从包中加载的函数）， body() 函数可以返回函数体的代码， args() 可以返回参数列表。结合 deparse() 可以将表达式转换为字符串。

Progress developers have a hidden weapon: the startup parameter. This is not a decompiler, but a disassembler.

Decompiling a Progress .r file is a necessary skill for maintaining or modernizing legacy OpenEdge systems. While tools like ProDecompiler can provide a starting point, successful recovery requires a thorough understanding of 4GL programming to interpret, fix, and rebuild the resulting code.

library(progressr) handlers(global = TRUE) handlers("txtprogressbar") decompile_archive <- function(file_list) p <- progressor(steps = length(file_list)) for (file in file_list) p(sprintf("Processing %s...", basename(file))) # [Decompilation logic goes here] Use code with caution. 4. Reverse Engineering Compiled Binaries (.so / .dll)

然而，对于已被字节码编译的函数， body() 返回的仍然是原始的R代码——。这意味着在绝大多数情况下，从加载的包中提取函数源代码是可行的。 # Load the tools library library(tools) # Define

Before attempting recovery, you must identify how your R code was saved or packaged. R code typically exists in three states.

Your (debugging, porting, or recovering lost work)

Open the resulting text file in a code editor like VS Code to modify the asset paths. 6. Best Practices for Rebuilding Code

If you have an R package ( .rda , .RData , or similar), you might consider:

Another historical player was (UK), which offered a service to decrypt source code encrypted with the Progress xcode utility, but they appear to no longer be in business. Other solutions have come and gone, like tools from Joanju Software and a "partially functioning decompiler" reportedly written by a developer in Brisbane. Even a quick search reveals claims of a tool named "PROGRESS R-Code Decompiler 2022.9" being released by a private entity with improved WHERE clause processing, though still cited as "a little unstable".

When processing large packages, batch-decompiling hundreds of .rds files, or analyzing massive codebases, tracking your progress prevents data loss and helps estimate completion times. Using Progress Bars in Recovery Scripts
