The :YcmDiags command

Calling this command will fill Vim's locationlist with errors or warnings if any were detected in your file and then open it. If a given error or warning can be fixed by a call to :YcmCompleter FixIt, then (FixIt available) is appended to the error or warning text. See the FixIt completer subcommand for more information.

The :YcmShowDetailedDiagnostic command

This command shows the full diagnostic text when the user's cursor is on the line with the diagnostic.

The :YcmDebugInfo command
