only useful if you want to dig deeper into Jinja2 or develop extensions. class jinja2.Environment([options]) The core component of Jinja is the Environment. It contains important shared variables like configuration need to modify internals of how template variables are handled. For details, see Context. overlay([options]) Create a new overlay environment that shares all the data with the cur- rent environment except zipfile. By default template compilation errors are ignored. In case a log function is provided, errors are logged. If you want template syntax errors to abort the compilation you can set ignore_errors to
