Describe the bug

Generally bat and yazi have similar results when highlighting a file. I noticed there are some special cases this isn't true: bat provides syntax highlighting but yazi does not highlight the syntax.

Expected Behavior

yazi shows syntax highlighting like bat

To Reproduce

For example, bat is able to highlight its own config file

But yazi shows this file as unhighlighted

Configuration

https://github.com/mikavilpas/dotfiles/blob/98e2c1122657a096425e7967a9a24c340f8f60b6/.config/yazi/yazi.toml?plain=1#L1

Anything else?

This seems to be a feature of bat, using the following heuristics that are based on file paths and names: https://github.com/sharkdp/bat/blob/c264ecd26b16ebb4f309db03d5a16b1f6e38ca67/src/syntax_mapping/builtins/README.md?plain=1#L1

I'm not sure what files are highlighted or not. As far as I can see, yazi just calls syntect to figure out what syntax should be used.

Do you think this should be fixed?

[sxyazi]

Nice to have, but I think it should use mine-type as the fallback rather than path as this will allow users to choose desired mime fetcher to meets their different needs

[sxyazi]

Or maybe only use mine-type (instead of the extension of current implementation) since it's more accurate and flexible

Hey, great project :)
I have a similar problem with $ file returning
test.xopp: gzip compressed data, from Unix, original size modulo 2^32 8510711
which technically is correct. (yazi unzips it succesfully and data makes sense)
However I want these files (having a mimetype of application/x-xopp) to be opened by xournalpp
As expected xdg-open works just fine
