Resolve relative paths

[atrskv]

Problem

The current implementation works fine with absolute paths, as described in the README.md, but does not support relative paths such as .venv/bin/python

For example, running:

which python

returns:

/Users/yourname/projects/my-project/.venv/bin/python

While this absolute path works, it includes the project-specific folder name, meaning you need to update settings.json every time you switch projects

You can use a relative path like:

{
  "pythonFuncRunner.pythonPath": ".venv/bin/python"
}

And it works: when we tap the Run button, it executes the command:

".venv/bin/python" -m pytest -rpP tests/...

However, debugging fails because the debugger does not resolve relative paths against the workspace folder

Proposed solution

Introduced a new utility function resolvePythonPath which checks if the provided path is absolute. If the path is relative, resolves it against the workspace folder to produce an absolute path:

function resolvePythonPath(configPath: string, uri: vscode.Uri): string {
  if (path.isAbsolute(configPath)) return configPath;

  const workspaceFolder = vscode.workspace.getWorkspaceFolder(uri);
  if (!workspaceFolder) return configPath;

  return path.join(workspaceFolder.uri.fsPath, configPath);
}
