Oh My Fish is a framework and plugin manager for the Fish shell.

Packages are cloned under $OMF_PATH and recorded in the user’s bundle file. Oh My Fish manages two kinds of package, plugins and themes, and reports both from one listing: mpm yields them together, since a name is unique across the two and every mutating command takes either.

What `mpm` adds to `oh-my-fish`¶

mpm reaches across every manager at once, not oh-my-fish alone: mpm installed and mpm outdated cover oh-my-fish alongside every other manager you run in one table, mpm upgrade --all updates them together, and mpm sbom exports the whole machine as one bill of materials.

Every mpm command also gains --dry-run and --plan previews, cross-scheme version comparison and purl identifiers. See manager augmentations for how each one is built.

Your `oh-my-fish` commands, in `mpm`¶

You already know oh-my-fish: each operation maps one-to-one onto mpm, in an interface shared by every manager.

To…	With `oh-my-fish`	With `mpm`
Install a package	`omf install z`	`mpm install pkg:oh-my-fish/z`
Upgrade one package	`omf update z`	`mpm --oh-my-fish upgrade z`
Upgrade everything	`omf update`	`mpm --oh-my-fish upgrade --all`
Remove a package	`omf remove z`	`mpm remove pkg:oh-my-fish/z`

Prefix any command above with --dry-run to simulate the underlying manager calls without touching the system: the safe way to watch what mpm would do before trusting it.

Operations¶

Operation	Supported	Notes
`installed`	✅
`outdated`	❌	Oh My Fish compares nothing against its remotes short of performing the update; `upgrade --all` still works.
`orphans`
`search`	❌	The `omf search` output comes from a private helper no upstream sample pins down, so a parser would be a guess.
`install`	✅
`upgrade`	✅
`upgrade_all`	✅
`remove`	✅
`sync`
`cleanup`
`doctor`

Configuration¶

Ignore oh-my-fish on the mpm CLI by passing the --no-oh-my-fish option.
Ignore it for every run in your configuration:
```
[mpm]
oh-my-fish = false
```

Raise the timeout of all oh-my-fish calls:

[mpm.overrides.oh-my-fish]
timeout = 900

Run mpm config-template oh-my-fish to print all overridable settings for your configuration file:

[mpm.overrides.oh-my-fish]
cli_names = [
    "fish",
]
cli_search_path = []
dry_run = false
ignore_auto_updates = true
plan = false
post_args = []
pre_args = []
pre_cmds = []
requirement = ">=6.0.0"
stop_on_error = false
unmaintained = false
version_cli_options = [
    "--version",
]
version_regexes = [
    "Oh My Fish version (?P<version>\\S+)",
]

[mpm.overrides.oh-my-fish.extra_env]
NO_COLOR = "1"

The arguments and environment variables listed in the box atop this page are forced on every oh-my-fish call, so runs stay quiet, non-interactive and reproducible: the defaults you would set in CI anyway.

Recipes¶

A few jobs you would otherwise script around oh-my-fish, one mpm command each:

Snapshot and clone a machine: mpm --oh-my-fish dump oh-my-fish.toml, then mpm restore oh-my-fish.toml on the next one.
Export a compliance SBOM: mpm --oh-my-fish sbom (CycloneDX by default, --spdx for SPDX).

Privilege escalation¶

mpm runs this manager as the current user and never prepends sudo by default. Flip the policy for its privileged operations with --sudo or the per-manager sudo override.

None of its operations is privileged.

See privilege escalation for the full policy.

Cooldown¶

State of Fish Oh My Fish’s release-age gating, from the cooldown support table:

Status: ❌ None (clones a Git branch or tag, no release feed)

A cooldown only pays off where a compromised release can be withdrawn while the clock runs, and can only be emulated where the registry dates its releases. From the retraction table:

Registry: Upstream Git clones
Retraction: None: a plugin is cloned straight from its upstream repository, so withdrawing a bad revision is its author force-pushing, retagging or deleting it themselves. No index sits in between
Publish date: ❌ a commit or tag date is set by the author and freely rewritable

With --cooldown set, mpm skips this manager’s install and upgrade operations rather than run them unguarded (fail-closed); --cooldown best-effort opts back in.

Version check¶

The version is probed by running:

$ fish --version
Oh My Fish version 7

and extracted with:

r"Oh My Fish version (?P<version>\S+)"
