Is there a way to provide input to interactive programs?

Currently not, however this should be quite easy to implement. I just need to create an additional mode which uses Comint instead of Compile. The downside is that comint-mode isn't as rich as compile-mode, This will be an optional global variable which can be enabled.

Sorry for getting back at this so late, I've been pretty busy and (sadly) haven't done any Rust dev for a long while. IIRC I looked into this in January but there were some complications that made this harder than I initially thought. I don't know when I'll have time to look into this but pull requests are always welcome. Again sorry for this.

This is a real pain that should be easy to resolve. At line 303 in cargo-process.el inside the function cargo-process--start (https://github.com/kwrooijen/cargo.el/blob/master/cargo-process.el#L303), compilation-start is executed without comint mode. From the docs:

(compilation-start COMMAND &optional MODE NAME-FUNCTION HIGHLIGHT-REGEXP) ... MODE is the major mode to set in the compilation buffer. Mode may also be t meaning use ‘compilation-shell-minor-mode’ under ‘comint-mode’.

Okay, I solved it this way: https://emacs.stackexchange.com/a/51194/23748. Perhaps this can be used to solve the problem?

I slightly modified the solution provided by @SimonCockx to move your point to the end of the compilation buffer. This makes it so that you can type your input in directly after running the function.

(with-eval-after-load 'rust-mode
  (define-key rust-mode-map (kbd "C-q") 'my-cargo-run))
(defun my-cargo-run ()
  "Build and run Rust code."
  (interactive)
  (cargo-process-run)
  (let (
      (orig-win (selected-window))
      (run-win (display-buffer (get-buffer "*Cargo Run*") nil 'visible))
    )
    (select-window run-win)
    (comint-mode)
    (read-only-mode 0)
    (end-of-buffer)
  )
)

(defun my-cargo-run ()
  "Build and run Rust code."
  (interactive)
  (cargo-process-run)
  (let (
      (orig-win (selected-window))
      (run-win (display-buffer (get-buffer "*Cargo Run*") nil 'visible))
    )
    (select-window run-win)
    (comint-mode)
    (read-only-mode 0)
    (end-of-buffer)
  )
)

This enables the input but nothing else, if even fails when the program tries to println a string after the read line.

None of these solutions work for me. Was this finally fixed in some other way?
