neovim map command strangeness

Question

Using neovim. Since hlsearch is on, after the search and replace operation the strings are highlighted. Pressing <C-l> clears the highlight.

I have this keymap to convert a line to title caps:

map('n', 'tc', ':s/\\v<(.)(\\w*)/\\u\\1\\L\\2/g<cr><C-l>', default_opts)

The above works except for clearing the highlighting.

If I use from within neovim:

:nmap tc :s/\v<(.)(\w*)/\u\1\L\2/g<cr><C-l>

things work properly.

What is wrong with the earlier sequence?

Answer 1

I would do:

:nmap tc :s/\v<(.)(\w*)/\u\1\L\2/g<cr>:noh<cr>

If you have a mapping that link <C-l> to :noh your solution rely on the recursivity of the mapping.

map('n', '<C-l>', ':noh<cr>', { noremap = false })
map('n', 'tc', ':s/\\v<(.)(\\w*)/\\u\\1\\L\\2/g<cr><C-l>', { noremap = false })
