I have configured PS1 and made the entire prompt bold
.zshrc contains as follows
PS1="%{$fg_bold[yellow]%}%n@%m %{$fg[blue]%}%~ \$ %{$reset_color%}%{$fg_bold[white]%}"
preexec() { printf "\e[1m"; }
Whatever I type in after the prompt is appearing bold only when I load from the buffer.
For example, as shown here me typing echo "this is text" does not appear in bold.
I am on Ubuntu 18.04 and am trying to move to zsh.
The Zshell Line Editor (zle) lets you format the command buffer.
PS1='%F{yellow}B%n@%m %F{blue}%~ \$ %f%b' # simplified prompt
zle_highlight=(default:bold,fg=white)
More information about how to use zle_highlight can be found in man zshzle.
Based on the linked screenshot, it looks like something is already formatting your the command input; you may want to run print $zle_highlight first to see its current value and modify it accordingly, or research your existing configuration for the source of the current colorization.
