# dnf-repo

A wrapper of the dnf package manager for fine control of
enabled/disabled yum repos (eg Copr repos).

dnf is the package manager used by Fedora Linux, Centos Stream, and RHEL.

DNF can get slower with many repos enabled because it attempts
to refresh its cached repodata frequently. So it can be advantageous
to disable some small repos by default and only enable them periodically
as needed.

This tool can temporarily enable/disable repo(s) selected by substring(s).
Changes to repos' enabled states can be saved too.
It is also possible to expire repo caches individually.

There are also smart options to enable/disable testing repos
(and even source/debuginfo repos),
and also to add Copr repo or Koji repo file.

```

## Usage examples
List repos:
```shellsession
$ dnf-repo [--list]
```

Update with testing repos enabled:
```shellsession
$ dnf-repo -t update
```

Note that sudo is used implicitly when needed:
there is no need to run dnf-repo with sudo.

### Copr
List disabled copr repos (ie lists copr repos that would be enabled):
```shellsession
$ dnf-repo -e copr
```

Disable active copr repos for update:
```shellsession
$ dnf-repo -d copr update
```

Install a package directly from a new copr:
```shellsession
$ dnf-repo -c varlad/helix install helix
```
(note the copr repo is not permanently enabled).

Later update with the copr:
```shellsession
$ dnf-repo -e helix update
```

### Changing system repo config
Disable fedora modular and cisco openh264 repos permanently:
```shellsession
$ dnf-repo --M -d h264 --save
```
(All modular repos were dropped in Fedora 39.)

### Use only source repos
```shellsession
$ dnf-repo -d \* --enable-source
with enabled 'fedora-source'
with enabled 'updates-source'
with disabled 'fedora'
with disabled 'updates'
```

### Switch system from rawhide
Switch a system from Rawhide to F40:
```shellsession
$ dnf-repo -d rawhide -e fedora distrosync --releasever 40 fedora-\*
with disabled 'rawhide'
with enabled 'fedora'

:
```

### Repo patterns
By default repo patterns are matched as infix substrings
(unless you use `--exact`).

But you can also prepend `^`/append `$` (or both) to match a repo name
from its beginning/end (or exactly).

You can also use glob patterns to match one or more repo names:
see the [supported Glob syntax](https://hackage.haskell.org/package/Glob/docs/System-FilePath-Glob.html#v:compile).

Without a glob (eg '*') a shortest common repo match will be sought,
otherwise all matching repos will be considered.

An initial `^` (final `$`) in a glob pattern prevents
the automatic prepending (appending) of `*` before (after) the pattern.

Repo actions expand to a sequence of `--enablerepo=`, `--disablerepo=`,
`--repo=`, etc, so as usual later settings will overrule conflicting
earlier settings.
