Add doc about usage with vim-plug

[edi9999]

When I try the following :

call plug#begin('~/.config/nvim/plugged')
Plug 'kevinhwang91/nvim-hlslens'
call plug#end()
lua require('hlslens').setup()

I get following error :

line  260:
E5108: Error executing lua [string ":lua"]:1: module 'hlslens' not found:

        no file './hlslens.lua'

It worked well a few months ago (can't tell when exactly it stopped working).

It would be great to add installation instruction for vim-plug.

Also, I'm not much used to using lua in my .vimrc, it would be great to tell more about where you are putting the following :

require('hlslens').setup()
local kopts = {noremap = true, silent = true}
....
...

I haven't used vim-plug for a long time. It will hack rtp. I think we should make hlslens work fine with built-in package, h 'packpath'. packer.nvim is a wrapper for built-in package. If you want hlslens work with vim-plug, PR is welcome.

Hi @kevinhwang91,

I'm currently working on this issue. May I know why we have to use vim.schedule in this case to call the setup function?

I can see the function called in setup file but in the guideline, we have to call it again (with different parameters though).

Thanks in advance!

May I know why we have to use vim.schedule in this case to call the setup function?

Because the initial sequence of plugins may make nvim abnormal. User should initialize hlslens explicitly.

I can see the function called in setup file but in the guideline, we have to call it again (with different parameters though).

Just to warn user invoke setup
