-## Redirect asset_url
-
-For some extensions (such as codelldb), there is only a downloader in vscode markplace, and the real location of the extension is on github. At this time, asset_url is allowed to be redirected:
-
-```toml
-vscode_version = "1.81.1"
-
-[[extensions]]
-publisher_name = "vadimcn"
-extension_name = "vscode-lldb"
-asset_url = '''
-https://github.com/vadimcn/codelldb/releases/download/v{{ extension.version }}/codelldb-{{ system.arch }}-{{ system.ostype }}.vsix
-'''

-asset_url is a jinja template string.
