powerlevel10k is a popular zsh theme and my favorite one. However, branch names are truncated if these are pretty long.
Although, you can remove this limitation by updating its config file:
vim ~/.p10k.zsh
Search for the branch
name and comment the line that’s doing the truncation:
# Tip: To always show local branch name in full without truncation, delete the next line.
# (( $#branch > 32 )) && branch[13,-13]="…" # <-- this line
You might need to restart zsh
exec zsh
