Description
When trying to debug in VSCode on Ubuntu with GNU gdb (Ubuntu 16.2-8ubuntu1) 16.2 I wasn't able to see nice printouts in the variables pane or debug panel.
For example a String just shows the raw underlying Vec
Thanks to this thread:
https://users.rust-lang.org/t/vscode-gdb-rust-analyzer-pretty-printing/73705
I was able to get things working by following OP's tip on including the VSCode settings
{
"rust-analyzer.debug.engine": "ms-vscode.cpptools",
"rust-analyzer.debug.engineSettings": {
"cppdbg": {
"miDebuggerPath": "${env:HOME}/.cargo/bin/rust-gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": false
}
]
}
}
}
Could these be enabled by default so everyone can easily see your great GDB integration?

Research direction
Start by tracing the rust-analyzer.debug.engine and rust-analyzer.debug.engineSettings configuration for the ms-vscode.cpptools debugger. Compare the supplied cppdbg setupCommands with the existing defaults, then check the relevant debugger integration tests if available. Done means Rust debugging enables GDB pretty-printing by default without requiring those user settings.
