Moving to the Beginning of the Line
May 26, 2015
When I started using Vim, one of the first custom mappings I added to my
.vimrc was moving to the beginning of the line with
H and moving to the end of the line with
" Jump to beginning of line noremap H 0 " Jump to end of line noremap L $
I talked about this with fellow Vimmer [@benjamin]benjamin, and he said the mapping was slightly awkward because it’s rare he wants to move to the beginning of the current line, and in most cases he’d actually rather move the cursor to the first non-whitespace character of the line.
I like Benjamin’s idea of moving to the first non-whitespace character, but I don’t want to lose the ability to move to the first column of the line. To remedy this, I wrote a short function that moves the cursor to the first non-whitespace character of the current line, or moves the cursor to the first column if it was already on the first non-whitespace character.
" Jump to first character or column noremap <silent> H :call FirstCharOrFirstCol()<cr> function! FirstCharOrFirstCol() let current_col = virtcol('.') normal ^ let first_char = virtcol('.') if current_col <= first_char normal 0 endif endfunction
The function above works by first checking the column that the cursor is currently on and storing it in
current_col. We then move the cursor to the first non-whitespace character and check the column again. If they are the same — meaning the cursor was already on the first non-whitespace character — we move the cursor to the first column.
