Answer 1

Here are the steps to debug a revel framework (golang) app in vscode.

1. Import revel project folder into vscode
2. Edit ~/.vscode/launch.json so that it looks like the following: (replace values in <> with values for your own local env.

{ "version": "0.2.0", "configurations": [ { "name": "Launch", "type": "go", "request": "launch", "remotePath": "", "port": 2345, "host": "127.0.0.1", "mode": "debug", "program": "${workspaceRoot}/app/tmp/", "env": {}, "args": ["-importPath", "<project folder name>", "-srcPath", "C:\\Users\\<username>\\go\\src", "-runMode", "dev"] } ] }

Note that -importPath should be the directory (relative to $GOPATH\src where your project lives)

Note that the value for -srcPath should match your $GOPATH\src directory (I'm running on Windows)

Once your launch.json is set up as so, you can start the app in deb mode and put breakpoints wherever you wish.
