how do I remove the blank line before title

[duan-1]

There has a blank line before title when I open Konsole. even I run 'clear' command, this line still here.

This behavior comes from the Pure prompt, not Zim. Pure is a third-party prompt.

You can find a suggestion to achieve what you want at sindresorhus/pure#509 (comment). However, this is hacky and unsupported, so I'd recommend forking the prompt and making it your own instead.

Remove the line below, then perform the following change to your config:

diff --git a/pure.zsh b/pure.zsh
index dab82aa..9521240 100644
--- a/pure.zsh
+++ b/pure.zsh
@@ -188,7 +188,7 @@ prompt_pure_preprompt_render() {
 
 	if [[ $1 == precmd ]]; then
 		# Initial newline, for spaciousness.
-		print
 	elif [[ $prompt_pure_last_prompt != $expanded_prompt ]]; then
 		# Redraw the prompt.
 		prompt_pure_reset_prompt

-zmodule sindresorhus/pure --source async.zsh --source pure.zsh
+zmodule duan-1/pure --source async.zsh --source pure.zsh

Apply with zimfw uninstall && zimfw install.

But the default theme also has a blank line, this is the reason why I use pure. Then I found pure also has a blank line, it made me think is the zim's promble.

That's a good point. asciiship draws some inspirations from pure and spaceship, and just like them its prompt starts with an empty line: asciiship.zsh-theme#L50-L52.

Same procedure if you want to get rid of it: fork, remove the leading newline character at line 50, and use the forked version in your config.

thx a lot. I used powerlevel10k finally, it can also achieve the same effect as pure. No more blank line now! :D
