Describe the bug When the file text is too long, there is a problem

E339:Pattern too long
vim-illuminate: An internal error has occured: false".../start/vim-illuminate/lua/illuminate/providers/regex.lua:26: regex: internal error"

Screenshots Screenshots

If I disable the text file type, although it will not report an error, the cursor movement in the file will become stuck.

require('illuminate').configure({
    filetypes_denylist = {
        'text',
        'NvimTree',
        'dirvish',
        'fugitive',
    },
    -- filetypes_allowlist = {
    --     'cpp',
    --     'py',
    -- },
})

The issue is likely an internal Neovim error with lines that are too long, in the screenshot I don't see how long the line is, can you share that info? Something :echo col('$').

This is the file, 1 line, 999999 columns

test_input.txt

If I disable this plugin, nvim doesn't have any problem.

Yup that might do it.

If I disable this plugin, nvim doesn't have any problem.

To be clear, when I say internal I mean internal to vim.regex which is used by vim-illuminate.

I'll push a check for large lines later.

[tengtengh]

Well, even with the plugin disabled, nvim still slows down when encountering large lines. It's really not a plugin problem

Reopening, I do have changes I want to add relating to this even if it won't fully fix the issue.
