Using `bat` would result in the command being a nested list.
eg. using `:Telescope plaents` with `bat` installed
```
{
"bat",
{ "--pager", "less -RS" },
"--style=plain",
"--color=always",
"--paging=always",
"--",
"/home/jt/projects/telescope.nvim/data/memes/planets/earth",
}
```
This would cause `vim.fn.termopen` to throw an error as the command is
expected to be a flat list or string.
* fix(previewer): improve binary mime type check
Problem: mime type for a ts/js file can either return `text/plain` or
`application/javascript` based on the contents of the file.
Previously, this meant `application/javascript` would be considered
"possibly binary". This, in conjunction with how `vim.filetype.match`
does not give a result for a filename that ends in `.ts`, would lead to
a typescript file taking the path of `check_mime_type` and eventually
`mime_hook`.
Solution: Include `application/javascript` as a non-binary file type
during mime type check.

This commit fixes the following error:
E5108: Error executing lua: Vim:Can't send data to closed stream
stack traceback:
[C]: in function 'chansend'

/lua/telescope/actions/init.lua:222: in function 'run_replace_or_original'
This happens when previewers.new_termopen_previewer()'s get_command()
ends without pagination.
Telescope creates most floating windows with `noautocmd = true`, so
these windows do not trigger autocommands, but preview buffer is set in
window using `nvim_win_set_buf()`, which triggers buffer autocommands.
This may be unwanted, so block them using 'eventignore'.
- new git previewers
- jump to line in bcommit previewer
- vimdiff for bcommits
- dynamic preview window titles
- more previewers documentation
Cycle previewers are not mapped yet. So you need to setup yourself:
```lua
require('telescope').setup {
defaults = {
mappings = {
i = {
["<C-s>"] = actions.cycle_previewers_next,
["<C-a>"] = actions.cycle_previewers_prev,
},
},
}
}
```

Configure preview window with:
autocmd User TelescopePreviewerLoaded setlocal wrap
autocmd User TelescopePreviewerLoaded setlocal number
file_maker example: Use regex highlighting for certain filetype like `*min.js` because they slow
down things with treesitter highlighter. Just a snippet for tests. We will do an extension :)
local previewers = require('telescope.previewers')
local putils = require('telescope.previewers.utils')
local pfiletype = require('plenary.filetype')
local _bad = { '.*%.min%.js' }
local bad_files = function(filepath)
for _, v in ipairs(_bad) do
if filepath:match(v) then
return true
end
end
return false
end
local new_maker = function(filepath, bufnr, bufname, use_ft_detect, callback)
if use_ft_detect == nil then use_ft_detect = true end
if bad_files(filepath) then
previewers.buffer_previewer_maker(filepath, bufnr, bufname, false, callback)
local ft = pfiletype.detect(filepath)
putils.regex_highlighter(bufnr, ft)
else
previewers.buffer_previewer_maker(filepath, bufnr, bufname, use_ft_detect, callback)
end
end
require('telescope').setup {
defaults = {
buffer_previewer_maker = new_maker,
}
}
