Describe the question

I am trying to get yazi to assoicate with a gentoo .ebuild script, to open with nano.

I have tried the usual methods of mimetype assoications for files, but I can't get it to work, .desktop file, and mimeapps.list

Nothing I've done seems to be working.

I want to be able to hit enter and have these ebuilds open with nano.

I use fish and I've also set in the config.fish; set -gx EDITOR nano

I'm clueless here LOL, this is what I wrote up in yazi.toml, but it's not working.

[manager]
show_hidden = true

[opener]
edit = [
{ run = "$EDITOR %s", block = true, for = "unix" },
]

[open]
rules = [
{ url = "*.ebuild", use = "edit" },
]

When I hightlight over a .ebuild script all it says in the Pane;

File Type Classification

Gentoo ebuild, EAPI 8, ASCII text

I hightlighted a .ebuild script, pressed : and typed this in;

shell --block "/bin/sh -c '/usr/bin/nano %0'"

Then I got exited with Status 127. Does this mean yazi is essentially "blind" to the filesystem's binaries? hmm

I also tried around 15 different settings/options in the yazi.toml, then later added a keymap.toml;

[[manager.prepend_keymap]]
on = [ "" ]
exec = "open --interactive"
desc = "Open with selection"

I can come up with nothing to make this work....

THANKS

Anything else?

Well after chasing around with the AI for 5 days and several hours, finally came up with a working solutiion. It appears the URL was the change needed.

Where's the humans when ya need them... LOL 🤪

[opener]
edit = [
    { run = 'nano "$@"', block = true, desc = "Edit with nano" }
]

[open]
prepend_rules = [
    # Match by file extension (Updated 'url' syntax)
    { url = "*.ebuild", use = "edit" },

    # Match by common text mime-types just in case
    { mime = "text/*", use = "edit" },
    { mime = "application/x-sh", use = "edit" },

    # Specific Gentoo mime-type
    { mime = "application/vnd.gentoo.ebuild", use = "edit" }
]

P.S. I love yazi, thanks for this amazing file manager! 👍

But now I don't know if I'm running into a bug, because when I have highlighted the .ebuild, in the right side pane it says;

 File Type Classification
Gentoo ebuild, EAPI 8, ASCII text 

Here is the content of one of the ebuilds I am testing this on;

# Copyright 1999-2026 Gentoo Authors
# Distributed under the terms of the GNU General Public License v2

EAPI=8

inherit go-module

DESCRIPTION="A pass extension for command-line interfaces"

DEPEND="${RDEPEND}"

src_compile() {
        ego build
}

src_install() {
        dobin pass-cli
}

Now f I commented #EAPI=8 out then I can see the preview....

This is my yazi.toml

[manager]
show_hidden = true

[opener]
edit = [
    { run = 'nano "$@"', block = true, desc = "Edit with nano" }
]

[open]
prepend_rules = [
    # Match by file extension (Updated 'url' syntax)
    { url = "*.ebuild", use = "edit" },

    # Match by common text mime-types just in case
    { mime = "text/*", use = "edit" },
    { mime = "application/x-sh", use = "edit" },

    # Specific Gentoo mime-type
    { mime = "application/vnd.gentoo.ebuild", use = "edit" }
]

[plugin]
prepend_previewers = [
  { name = "*.ebuild", run = "code", sync = true },
  { mime = "application/vnd.gentoo.ebuild", run = "code", sync = true }
]

[previewer]
prepend_rules = [
  { mime = "application/*", run = "code" },
  { name = "*.ebuild", run = "code" },
  { mime = "application/vnd.gentoo.ebuild", run = "code" }
]

[preview]
max_width = 2000
max_height = 2000
# Set this to 10MB just to be absolutely sure
advisory_max_size = 10485760

I really need some help here please... THANKS 👍

I came up with the help of AI a working solution for gentoo ebuild and manifest files.

[mgr]
show_hidden = false

# Adjust the ratio for [parent, current, preview]
ratio = [3, 7, 7]

[opener]
edit = [
    { run = 'nano "$@"', block = true, desc = "Edit with nano" }
]

[open]
prepend_rules = [
    # 1. Match Gentoo Manifests
    { url = "**/Manifest", use = "edit" },

    # 2. Match ebuilds AND their variants (ebuild.orig, ebuild.new, etc.)
    # This uses filename matching because, as you noted, these aren't 
    # standard XDG mimetypes that the system identifies automatically.
    { url = "*.ebuild*", use = "edit" },

    # 3. Handle standard text/scripts (for your .py.orig, .sh.new, etc.)
    # This relies on the internal magic-byte logic you mentioned.
    { mime = "text/*", use = "edit" },
    { mime = "application/x-sh", use = "edit" }
]

[plugin]
prepend_previewers = [
    # Ensure the previewer also catches the renamed ebuild files
    { url = "*.ebuild*", run = "code" },
    { url = "**/Manifest", run = "code" },
    # Catch-all for other text-based code previews
    { mime = "*{gentoo,text}*", run = "code" }
]
