### System details

Beelink Ser9 Pro, Omarchy 2.1.1

### What's wrong?

Apologies in advance if this should actually be filed against something upstream. I'm still trying to get the lay of the land. I've actually managed to resolve this issue for myself, but thought I'd file this in the hope of helping others.

## Problem description:

I would like text files matching the glob `*.sgf` to be recognized as [smart game format](https://en.wikipedia.org/wiki/Smart_Game_Format) Go boardgame records. There is a mime filetype association already correctly defined for these files in `/usr/share/mime/packages/freedesktop.org.xml` (that ships with Omarchy). 

The correct mime filetype for `.sgf` files is `application/x-go-sgf` which is a sub-class of `text/plain`, but, unfortunately, the command `xdg-mime query filetype <file>.sgf` does **NOT** use the mime filetype database correctly by default.

## Background:

I specifically wanted Obsidian (and other apps) to open such files in my preferred application (Sabaki). It's easy to tell the Gnome File browser to use that app by default, but as near as I can tell, that _only_ affects the file browser application. Sadly, Obsidian or simply `open <file>` in a terminal would only launch `nvim` for sgf files.

In a terminal, `open <file>.sgf` (a shell function that calls `xdg-open`) only opens those files in nvim by default, because it's recognized as `text/plain`, and not as `application/x-go-sgf`. Same thing with pretty much any other application that can launch other programs on a file (maybe other Gnome apps follow the file browser associations?).

## Solution:

`xdg-mime` is actually just a shell script that by default uses `file -i` and the "magic" database to heuristically determine filetypes by looking at the file's initial contents. Despite the `xdg-mime` name and intended use, by default it apparently ignores the mime filetype definitions altogether (for reasons I fail to understand).

Interestingly, however, the script looks for a program with the name `mimetype` if it exists and uses that instead of `file` to determine a file's mime filetype.

The package repository includes `perl-file-mimeinfo` which includes the perl scripts `mimetype` and `mimeopen` which (hallelujah!) use the mime database definitions correctly.

Unfortunately, it installs these scripts in `/usr/bin/vendor_perl/bin`, so `xdg-mime` is unlikely to find them unless that directory happens to be in a user's PATH. I simply created symlinks in `/usr/bin` to these scripts which completely solved my issue.

## Request:

The above doesn't describe the several days of frustration (and ethanol consumption) involved in unraveling all of this. For the most part, everything in Omarchy JUST WORKED for me. Some of hardware stuff took some finagling, but this was my only real software issue.

I'd like to suggest that Omarchy distribute `perl-file-mimeinfo` by default, and that symlinks for `mimeinfo` and `mimeopen` get created by default.

No good deed ever goes unpunished, so I wouldn't be at all surprised if something currently depends on the currently incorrect mime detection algorithm. I've not uncovered any issues with the above solution yet, but I wouldn't call what I've done thus far a terribly robust QA.

Thanks for your consideration (and an awesome distribution!)
