<< R"help(cquery is a low-latency C/C++/Objective-C language server.
Command line options:
Mode:
--language-server
Run as a language server. This implements the language server
spec over STDIN and STDOUT.
--init <initializationOptions>
Override user provided initialization options.
--test-unit Run unit tests.
--test-index <opt_filter_path>
Run index tests. opt_filter_path can be used to specify which
test to run (ie, "foo" will run all tests which contain "foo"
in the path). If not provided all tests are run.
Other command line options:
--debug Disable libclang crash recovery so that in case of libclang or
indexer callback issue, the process will crash and we can
get a stack trace.
--init <initializationOptions>
Override user provided initialization options.
--log-stdin-stdout-to-stderr
Print stdin and stdout messages to stderr. This is a aid for
developing new language clients, as it makes it easier to figure
