* fix(help_tags): show help tags on windows (#3126)
On Windows, `builtin.help_tags` picker does not show any help tags.
To fix this, the following changes are needed:
1. `util.path_tail` checks unix separator `/` on Windows and leave the
original implementation intact on unix systems.
2. Line endings should be taken carefully on Windows. `vim.split` with
only newline `\n` character as separator may result in unexpected
crash when parsing large files. When splits on lines are needed, call
it with `\r?\n`, or even set up a wrapper function in utils is more
prefered.
Fixes#3126
* fix: handle cross platform line splits
* 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.

* fix(set_preview_message): check line height of previewer before setting message.
* style: run changed file through stylua and remove unused variable.
* refactor: change lines table instead. check max between line_pos and 0
* style: run changed file through stylua.
this follows nvim-treesitter more closely but enable can also be a table
of enabled languages
The config now looks like this:
```lua
defaults = {
preview = {
treesitter = {
enable = false,
-- or
enable = { "c" },
-- disable can be set if enable isn't set
disable = { "perl", "javascript" },
},
},
},
```
- introducing putils writer and use it rather than using PAGER env var
- introducing env for lua/telescope/_.lua job interface
- to respect MANPATH (and PATH just in case)
- fix for apropos output parsing might return e.g. `alacritty, Alacritty`
We need to split on first `,`
* For full configuration, see `:h telescope.defaults.preview`
* Unblocks previewer on binaries, too large files, and files that take too long to read
* Allows toggling treesitter highlighting for buffer_previewer
* Allows to globally opt out of previewer
* fix: stop leaking last preview buffer
* fix: formatting for docs
* fix: async check if file is dir or not and
- fix for in_fast_event when overriding file_maker
* fix: filtering for space in keymaps and fzy
* fix: show correct result numbers when using file_ignore_patterns
* Handle early close. Caused because we actually cleaning up buffers now
* cleanup
* [docgen] Update doc/telescope.txt
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 :)
