The readme file for bash-lsp lists among its features code completion and diagnostics. The mode line for, as well as highlighting within, debug.sh, seems consistent the shown excerpt of config.el. I was expecting a drop down menu with syntax suggestions while typing and that M-x flymake-show-buffer-diagnostics would list the error in the while statement. However, neither is occuring? What eventual minimal additions to the setup should I make, or what commands should I invoke, to obtain the desired behavior?
