## Global options for rlang

### Description

rlang has several options which may be set globally to control behavior. A brief description of each is given here. If any functions are referenced, refer to their documentation for additional details.

- `rlang_interactive`: A logical value used by `is_interactive()`. This can be set to `TRUE` to test interactive behavior in unit tests, for example.

- `rlang_backtrace_on_error`: A character string which controls whether backtraces are displayed with error messages, and the level of detail they print. See rlang_backtrace_on_error for the possible option values.

- `rlang_trace_format_srcrefs`: A logical value used to control whether srcrefs are printed as part of the backtrace.

- `rlang_trace_top_env`: An environment which will be treated as the top-level environment when printing traces. See `trace_back()` for examples.
