| `dlvFlags` | Extra flags for `dlv`. See `dlv help` for the full list of supported. Flags such as `--log-output`, `--log`, `--log-dest`, `--api-version`, `--output`, `--backend` already have corresponding properties in the debug configuration, and flags such as `--listen` and `--headless` are used internally. If they are specified in `dlvFlags`, they may be ignored or cause an error.<br/> | <center>_same as Launch_</center>|
| `env` | Environment variables passed to the launched debuggee program. Format as string key:value pairs. Merged with `envFile` and `go.toolsEnvVars` with precedence `env` > `envFile` > `go.toolsEnvVars`.<br/> | <center>_n/a_</center> |
| `envFile` | Absolute path to a file containing environment variable definitions, formatted as string key=value pairs. Multiple files can be specified by provided an array of absolute paths. Merged with `env` and `go.toolsEnvVars` with precedence `env` > `envFile` > `go.toolsEnvVars`. <br/> | <center>_n/a_</center> |
| `followExec` | (Experimental) Enables or disables follow exec mode.<br/>(Default: `false`)<br/> | <center>_n/a_</center> |
| `followExecRegex` | (Experimental) Regular expression. Only child processes with a command line that matches this regular expression will be followed during 'target follow-exec'.<br/>(Default: `""`)<br/> | <center>_n/a_</center> |
| `goroutineFilters` | Configures which system goroutines should be shown in the call stack. See https://github.com/go-delve/delve/blob/master/Documentation/cli/README.md#goroutines<br/>(Default: `""`)<br/> | <center>_same as Launch_</center>|
| `hideSystemGoroutines` | Boolean value to indicate whether system goroutines should be hidden from call stack view.<br/>(Default: `false`)<br/> | <center>_same as Launch_</center>|
| `host` | When applied to remote-attach configurations, will look for "dlv ... --headless --listen=<host>:<port>" server started externally. In dlv-dap mode this will apply to all other configurations as well. The extension will try to connect to an external server started with "dlv dap --listen=<host>:<port>" to ask it to launch/attach to the target process.<br/>(Default: `"127.0.0.1"`)<br/> | When applied to remote-attach configurations, will look for "dlv ... --headless --listen=<host>:<port>" server started externally.
