Attach to process

RubyMine provides a way to attach the debugger to both local and remote processes.

First off, if you want to debug a program that can be started from RubyMine, the best way to do it is to start a local debugging session.

Prerequisites

Attach to process requires the following components to be installed on the development machine:

  • If you use Linux, install GDB.

  • If you use macOS, make sure that LLDB is installed. Note that LLDB requires the six Python module, which may be missing in your macOS installation.

Attach to a local process

  1. Press Ctrl+Alt+F5 or choose Run | Attach to Process from the main menu.

  2. The list of running local processes is shown. Select the process to attach to.

    Search for a process to attach

    If necessary, narrow down the list of processes by typing the first letters of its name or PID.

    Search for a process to attach
  3. Proceed with debugging the same way as you usually do it in RubyMine (set breakpoints, step through, pause and resume the process, evaluate expressions, and so on)

    Note that in case the process you have attached to does not provide debug information, breakpoints will be unavailable and stepping will be performed in the disassembly view.

Detach from a process

The procedure to detach from a remote process is the same as for stopping a local debug session, however, the effect is different. When you detach, the debugging session closes but the process continues to run.

  • Click the Stop the Stop button button on the main toolbar on in the Debug tool window.

  • Alternatively, click Stop the Stop button on the main toolbar or press Ctrl+F2, then select the session to be closed.
