Rumble parameters

The parameters that can be used on the command line as well as on the planned HTTP server are shown below.

Shell parameter	HTTP parameter	example values	Semantics
--shell	N/A	yes, no	yes runs the interactive shell. No executes a query specified with --query-path
--query-path	query-path	file:///folder/file.jq	A JSONiq query file to read from (from any file system, even the Web!).
--output-path	output-path	file:///folder/output	Where to output to (if the output is large, it will create a sharded directory, otherwise it will create a file)
--log-path	log-path	file:///folder/log.txt	Where to output log information
--result-size	result-size	2000	A cap on the maximum number of items to materialize for large sequences within a query or for outputting on screen.
--overwrite	overwrite	yes, no	Whether to overwrite to --output-path. No throws an error if the output file/folder exists.
--print-iterator-tree	N/A	yes, no	For debugging purposes, prints out the expression tree and runtime interator tree.
--show-error-info	show-error-info	yes, no	For debugging purposes. If you want to report a bug, you can use this to get the full exception stack. If no, then only a short message is shown in case of error.
--server	N/A	yes, no	yes runs Rumble as a server on port 8001. Run queries with http://localhost:8001/jsoniq?query-path=/folder/foo.json
--port	N/A	8001 (default)	Changes the default port of the Rumble HTTP server to any of your liking
--variable:foo	variable:foo	bar	--variable:foo bar initialize the global variable $foo to "bar". The query must contain the corresponding global variable declaration, e.g., "declare variable $foo external;"
