I found from the vim's manual that we can echo colored text by the following command:

:echohl WarningMsg | echo "Warnging" | echohl None | echo ":Some warning"

which will highlight the string Warning and keep :Some warning in default color. My problem is that this will display the results in two lines, is there any way to display them in one line?

This should work:

function! EchoWarning(msg)
  echohl WarningMsg
  echo "Warning"
  echohl None
  echon ': ' a:msg

call EchoWarning('test')

This defined a simple function that you can call with the warning message as the argument.

As you see, the key is the echon command, which is similar to an echo except it does not add a newline at the end.

  • how can i specify other colors? such as green.

  • You can define a new highlight group (see :help :highlight) and use it instead of WarningMsg. Jun 8, 2021 at 16:16
