Keep selection highlighted

[Imlimp]

Is it possible to keep selected lines highlighted after commenting?

Yes, by using post_hook.

local U = require('Comment.utils')

require('Comment').setup({
    post_hook = function(ctx)
        -- Check whether we were in VISUAL mode
        if ctx.cmotion == U.cmotion.v or ctx.cmotion == U.cmotion.V then
            vim.cmd('norm! gv')
        end
    end,
})
