const LONG_ABOUT: &str = r#"
The Rerun command-line interface:
* Spawn viewers to visualize Rerun recordings and other supported formats.
* Start a gRPC server to share recordings over the network, on native or web.
* Inspect, edit and filter Rerun recordings.
"#;
// Place the important help _last_, to make it most visible in the terminal.
const ENVIRONMENT_VARIABLES_AND_EXAMPLES: &str = r#"
Environment variables:
RERUN_CHUNK_MAX_BYTES Maximum chunk size threshold for the compactor.
RERUN_CHUNK_MAX_ROWS Maximum chunk row count threshold for the compactor (sorted chunks).
RERUN_CHUNK_MAX_ROWS_IF_UNSORTED
Maximum chunk row count threshold for the compactor (unsorted chunks).
RERUN_SHADER_PATH The search path for shader/shader-imports. Only available in developer builds.
RERUN_TRACK_ALLOCATIONS Track memory allocations to diagnose memory leaks in the viewer.
WARNING: slows down the viewer by a lot!
RERUN_MAPBOX_ACCESS_TOKEN The Mapbox access token to use the Mapbox-provided backgrounds in the map view.
RUST_LOG Change the log level of the viewer, e.g. `RUST_LOG=debug`.
WGPU_BACKEND Overwrites the graphics backend used, must be one of `vulkan`, `metal` or `gl`.
Default is `vulkan` everywhere except on Mac where we use `metal`. What is
supported depends on your OS.
WGPU_POWER_PREF Overwrites the power setting used for choosing a graphics adapter, must be `high`
or `low`. (Default is `high`)
Examples:
Open a Rerun Viewer that listens for incoming SDK connections:
rerun
Load some files and show them in the Rerun Viewer:
rerun recording.rrd mesh.obj image.png https://example.com/recording.rrd
Open an .rrd file and stream it to a Web Viewer:
rerun recording.rrd --web-viewer
Host a Rerun gRPC server which listens for incoming connections from the logging SDK, buffer the log messages, and serve the results:
rerun --serve-web
Host a Rerun Server which serves a recording from a file over gRPC to any connecting Rerun Viewers:
rerun --serve-web recording.rrd
Host a Rerun gRPC server without spawning a Viewer:
rerun --serve-grpc
Spawn a Viewer without also hosting a gRPC server:
rerun --connect
Connect to a Rerun Server:
rerun rerun+http://localhost:9877/proxy
Listen for incoming gRPC connections from the logging SDK and stream the results to disk:
rerun --save new_recording.rrd
