VS Code is probably one of the most convenient code editors, it would be cool to make an extension for debugging applications on FASM or use an existing extension and somehow tweak it to generate and use a .fas debug file.

Some links I have already found:

These are my settings for CodeLLDB.

Steps:
- add settings below
- open your asm file
- add int3 instruction at the beginning
- press F5 twice for x86, once for x64

Sample file:
Code:
format PE64 GUI
; format PE GUI 4.0
; include 'win32a.inc'
entry @start

@start:
        int3
        mov eax, 3
        ret
    


.vscode/launch.json
Code:
{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "lldb",
      "request": "launch",
      "name": "Debug",
      "cwd": "${fileDirname}",
      "program": "${fileBasenameNoExtension}.exe",
      "preLaunchTask": "Сompile",
      "args": [],
    }
  ]
}
    


.vscode/tasks.json
Code:
{
  "version": "2.0.0",
  "tasks": [{
      "type": "process",
      "label": "Сompile",
      "command": "C:/FASM/FASM.EXE",
      "options": {
        "cwd": "${fileDirname}"
      },
      "args": ["${file}", "${fileBasenameNoExtension}.exe"]
  }]
}
    


settings.json
Code:
"terminal.integrated.env.windows": {
  "INCLUDE": "C:/FASM/INCLUDE",
}
