Modifying local variables and dape-read-memory

[seb-hyland]

Hi! I'm using code-lldb for Rust debugging. I can see the address of some variable n with p &n and I can edit it with p n = 50 or something, but is there a way to do this visually via dape? As well, If I take the output of p &n and try dape-read-memory on it (or run dape-read-memory on a stack frame) I get "Unknown EOL format in coding system: utf-8." Am I misinterpreting the purpose of dape-read-memory? I'm trying to understand what the line "Memory editor with hexl" in the README is referring to.

Hello!

Yes if you press the value of the variable in either Scope, Watch or Repl buffer or if point is at a line where the variable is shown it can be changed with =. This binding works in Repl if it's printed it richly (with colors), if you want print the var n richly the trick is to add whitespace before or after to get around the naming collision with the shorthand of the next command.

As for reading memory you are using it as intended (although the name of the function has been renamed to dape-memory). My version of code-lldb does not support memory read "Adapter not capable of reading memory", what version are you using?

If you (toggle-debug-on-error) does running dape-read-memory pop open a Backtrace buffer? If so would you mind sharing the contents.

I still have dape-read-memory on 0.23.0. The error given is:

Debugger entered--Lisp error: (error "Unknown EOL format in coding system: utf-8")
  error("Unknown EOL format in coding system: %s" utf-8)

  funcall-interactively(execute-extended-command nil "dape-read-memory" "dape-read")
  command-execute(execute-extended-command)

With regards to your comment on setting the variable via repl with rich printing, how do you determine if the repl prints richly? And what is the exact command for printing some var n? I know I can do p n or p n = 50 (or similar with expr, but is there some other specific thing dape likes?
