# dnf-repo

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

DNF is not terribly fast at handling repos partly because it likes
to refresh the cached repodata frequently. So it can be advantageous
to disable smaller repos by default and only enable them as needed
(eg periodically).

This tool can temporarily enable/disable repos selected by substring.
Repo states can also be saved or their cache individually expired.

There are options to enable/disable testing/modular repos,
and also to create a repo file for a Copr or Koji repo.

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

Update with testing repos:
```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 (actually shows "copr" repos that would be enabled):
```shellsession
$ dnf-repo -e copr
```

Disable all 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 by default).

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

### Changing system repo config
Disable modular and cisco h264 repos permanently:
```shellsession
$ dnf-repo --disable-defaults --save
```

To only disable modular you can use: `dnf-repo -M -s`.

### Switch system from rawhide
Switch a system from Rawhide to F37:
```shellsession
$ dnf-repo --exact -d rawhide -e fedora distrosync --releasever 37 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).

## Installation
A copr repo is available:
<https://copr.fedorainfracloud.org/coprs/petersen/dnf-repo/>

## Building
Use {cabal,stack,cabal-rpm} install.
