iTerm2 opens command response in vi like window - macos

Question

I have iTerm Build 3.3.9 installed. I have configured oh-my-zsh with following plugins & themes
ZSH_THEME="powerlevel10k/powerlevel10k"
ZSH_DISABLE_COMPFIX="true"
plugins=(aws git colored-man-pages colorize github virtualenv pip python osx zsh-syntax-highlighting zsh-completions zsh-autosuggestions django npm zsh-interactive-cd zsh-navigation-tools)
Now there are 2 issues that i am trying to solve
See the , I have written the command uptil aws cognito-i and remaining is appearing as autosuggestion. the problem is that with my setup (probably theme but i have tried multiple themes) i am unable to distinguish between the command that i have typed and the command is being suggested. normally suggested command should appear a little dimmer but its the same color/opacity as the one that i have written. how to fix this
The second issue is that whenever i run a command with aws cli (also with aws-nuke, the response is opened with a new vi type window, i.e., the commands get removed and i see blank window with each line starting with ~ and at the end of the window it says END. Why is it happening and how to fix this as well

Answer 1

To fix the first issue try moving zsh-syntax-highlighting to the very end of plugins. From zsh-syntax-highlighting FAQ:
Why must zsh-syntax-highlighting.zsh be sourced at the end of the .zshrc file?
zsh-syntax-highlighting.zsh wraps ZLE widgets. It must be sourced
after all custom widgets have been created (i.e., after all zle -N
calls and after running compinit). Widgets created later will work,
but will not update the syntax highlighting.
To fix the second issue add the following at the end of ~/.zshrc:
# Use `less` as pager in Zsh.
READNULLCMD=less
# Use `less` as pager in external commands.
export PAGER=less
# This affects every invocation of `less`.
#
# -i case-insensitive search unless search string contains uppercase letters
# -R color
# -F exit if there is less than one page of content
# -X keep content on screen after exit
# -M show more info at the bottom prompt line
# -x4 tabs are 4 instead of 8
export LESS=-iRFXMx4
