Is config.toml supported?

[eternal-devs-yk]

Hi, just curious lldb will support config.toml? (https://doc.rust-lang.org/cargo/reference/config.html)

I set [env] to retrieve additional environment variable but lldb does not seem to pick up.

Any update on this?

When I add this line to my lldb launch.json Configuration, which is Rust standard for handling configuration files, and I need to pass this into my executable as those variables are read into the runtime for the application to work properly:
"envFile": "${workspaceFolder}/.cargo/config/config.toml",

And then when I execute the debugger it returns with an error in a dialog box saying:

Internal debugger error: Error parsing line: '[env]', error at line index: 0

It seems like lldb can't handle the TOML table syntax of [env] which is what Rust config files must include to declare the section for environment variables. And without the [env] table header in that config.toml file then those variables won't be loaded into the application.

Here's the complete syntax...

launch.json

`{
            "type": "lldb",
            "request": "launch",
            "name": "Debug executable 'cargo run'",
            "cargo": {
                "args": [
                    "build",
                    "--bin=rust_react_app_hello_world",
                    "--package=rust_react_app_hello_world"
                ],
                "filter": {
                    "name": "rust_react_app_hello_world",
                    "kind": "bin"
                }
            },
            "envFile": "${workspaceFolder}/.cargo/config.toml",
            "args": [],
            "cwd": "${workspaceFolder}"
        }`

And here's the beginning snippet of the config.toml file:

[env]

# app server
app_server_url= "127.0.0.1:3000"
app_server_graceful_shutdown_max_duration="10" # In seconds
