LLDB is invoking Xcode to display source code all of a sudden. How to switch back?

I'm debugging a C project on Mac using LLDB, and the relevant source codes no longer displays inside LLDB commandline, but instead in Xcode.

How do I disable this?

(lldb) version
lldb-1700.0.9.502
Apple Swift version 6.1.2 (swiftlang-6.1.2.1.2 clang-1700.0.13.5)

About Xcode: Version 16.4 (16F6)

Solution

  • From LLDB help:

    --editor
              Tells the debugger to open source files using the host's "external editor"
              mechanism.

       -e     Alias for --editor

    Turns out, the particular program I debugged received the -e option (which I use to pass an expression on command line), and LLDB mistaken it for its own. Adding -- between lldb and the command to debug solved the problem.

    Is this a problem with file associations?

    Alternatively, if you prefer another GUI editor, you can keep the -e option, and associate the source code language with an editor of your preference, in my case, Emacs for C, and Kate for configs.
