To filter based on file contexts, you can use `-trace_file_context=...` flag along with `--trace_file=...` flag. These are the following options you can pass to the `-trace_file_context=...` flag (you can also pass them as list by separating them with comma). 1. `main`: Include trace output for file containing the main function. 2. `prelude`: Include trace output for prelude. 3. `import`: Include trace output for imports. 4. `include`: Include trace output for all. If the flag isn't used or non of the options are passed, by default only main file context is traced. File contexts are distinguished based upon the source location by passing the source location to `TraceStream::is_enabled(..)` as arguments. If no arguments are passed, file context is `FileContext::Unknown` and for now it will add the trace from unknown file context. Note: `import` option currently doesn't work as imports aren't supported yet. --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
