Setting the cursor to a vertical thin line in vim

Question

I am trying to set the cursor in insert mode to be a thin vertical line and I am unable to. I have tried this in my .vimrc file:

set guicursor+=i:ver100-iCursor

It does not set the cursor to a vertical bar on insert mode.

What am I missing and how do I do this?

Answer 1

This code in my /home/el/.vimrc worked for my console:

if $TERM_PROGRAM =~ "iTerm"
    let &t_SI = "\<Esc>]50;CursorShape=1\x7" " Vertical bar in insert mode
    let &t_EI = "\<Esc>]50;CursorShape=0\x7" " Block in normal mode
endif

Which does this for me:

Answer 2

This did the trick:

set guicursor=i:ver25-iCursor

I had to reduce the 100 to 25
