Debugging Zig (with a debugger)

I have been successful in running LLDB debugger from vscode on Linux, Mac and Windows with the following settings:

  • llvm-vs-code-extensions.lldb-dap visual code extension
  • lldp-dap executable must be in your path. Check that exists using lldb-dap --version. To install it on Windows run winget install LLVM.LLVM, on Mac brew install llvm, on Linux use your distribution package manager to install llvm/lldb.
  • Create an entry for the “LLDB DAP Debugger” in launch.json like:
    {
  "version": "0.2.0",
  "configurations": [
      {
          "type": "lldb-dap",
          "request": "launch",
          "name": "Debug",
          "program": "${workspaceFolder}/zig-out/bin/<your program>",
          "args": [],
          "env": [],
          "cwd": "${workspaceFolder}"
      }
  ]
}
  • In the vscode settings for the zig extension set "zig.debugAdapter": "lldb-dap". This allows to debug main and tests using the arrows in your code.

When i have the courage i will maybe try sometime again :slight_smile:
That’s the only thing I really miss since my delphi and C# days: just working out of the box.

Delphi especially. Came in an actual box too. :smiley:

If I had to write a Windows GUI program right now, odds are high that’s still how I’d do it.

Off topic :slight_smile:
Yes. I looked at C# for GUI’s but the amount of possiblities to choose from is dazzling and paralyzes me.

Hi. On Manjaro I install lldb-zig instead of lldb and in VSCodium the plugins CodeLLDB and Zig Language. I have a default lldb launch JSON and my user settings have:

"zig.zls.enabled": "on",
"lldb.library": "/usr/lib/lldb-zig/lib/liblldb.so",

If I use the regular lldb, extra work required to precisely indicate which line to break on, so the VSCodium does not work well. But that’s fixed in lldb-zig. This btw is independent from VSCodium.
