Fuzzy search of pacman repository and/or AUR repository at terminal

xmkx · 2021-08-31 18:43:18

I often have a hard time to find package name just because I don't remember all words in package. Is it possible to find it by fuzzy search?
I thought about to list all packages and filter it using | fzf
How to do that?

Don't use the last one, it does a partial upgrade whenever you "reload" (press Ctrl+R).

Wow. Thanks guys.
fuzzy-pkg-finder works great.

@Alad

You'd think an Arch "Wiki Admin" would know how to use pacman.

-Syy

doesn't upgrade.

-Su

upgrades.

RTFM

$ man pacman
...
         -y, --refresh
             Download a fresh copy of the master package database from the
             server(s) defined in pacman.conf(5). This should typically be used
             each time you use --sysupgrade or -u. Passing two --refresh or -y
             flags will force a refresh of all package databases, even if they
             appear to be up-to-date.

Yes he does and "-Syy" is not only retarded because of the second "y" which allows downgrade syncs and must never be used unconditionally and w/o explicit cause because it can invalidate your database, but it also syncs the database and thus any subsequent "pacman -S foo" will cause a partial upgrade.

It's the single biggest cause for partial upgrades to occur and, if implictly and silently caused by a script, borderline malign.

joehillen · 2021-09-02 16:18:28

I assure you there is no malice. I knew that `-Syy` was not recommended because it overloads the repo servers. I didn't know about the downgrade issue. I'll change it to `-Sy`.

joehillen · 2021-09-02 16:19:38

@seth

retarded

Is name-calling really necessary?

seth · 2021-09-02 16:34:30

I didn't call anybody ("you") names but qualified a parameter ("-Syy", rest assured, you're not the first or only source of that - the internet is full w/ this BS advice)
Also you could have gotten a less blunt comment but for your own post.

More importantly however, moving from -Syy to -Sy doesn't heal the fact that every subsequent package installation will be tainted. You want to use a secondary database.

You'd think an Arch "Wiki Admin" would know how to use pacman.

The irony of calling someone out for not knowing pacman, when you're unaware of the danger of partial upgrades after 6 years (edit: 8!) of using Arch, must be lost on you. There's been plenty of cases where people doing this ended up with a hosed system, e.g. on openssl/pacman upgrades.

Look at what checkupdates does instead.

How does one use a secondary database? Is that a common practice? I regularly do `-Sys`, so why not here?

I feel like your fear of `-Syy` is disproportionate to the risk. 8 years of Arch and I've never hit this problem even though I used `-Syy` for every upgrade for the first 4 (because everyone said to do that).

At any rate, I feel like these issues should be pointed out in the manpage rather than documented in forum posts.

Ok, I now see the confusion. paruz doesn't run `paru -Syy pkgname` it just runs `paru -Syy` (which is not a partial upgrade) and then reruns `paru -Ss pkgname`. This is exactly what is recommended (expect for the -Syy part, obviously)

And why isn't this in the manpage as well? Should `man pacman` just be a link the wiki?

Alad · 2021-09-02 17:19:02

The problem with pacman -Sy(y) is exactly the same, because the user could run pacman -S pkgname afterwards. In this case, likely without knowing something in the background ran pacman -Sy.

And why isn't this in the manpage as well? Should `man pacman` just be a link the wiki?

Pacman supports versioned dependencies, but Arch doesn't include them for most of its packages. Therefore no partial upgrades is an Arch policy, not a pacman one.

Raynman · 2021-09-02 17:20:05

Running Arch without consulting the wiki is unsupported?

I think pacman supports partial upgrades, but Arch doesn't. Arch doesn't have a man page (anymore?) and the policy is to ship vanilla packages, so the pacman man page doesn't get patched for Arch packaging policy. Systemd man pages also don't discuss the way Arch uses systemd, just the various possible ways to use it.

What confusion? Saying "it's exactly what's recommended, except it's not" seems confusing to me.

joehillen · 2021-09-02 17:35:35

@Alad Ok, so `-Sy` should only ever be run with `-u`, correct?

@Alad What I really want is to refresh the package list without leaving paruz, if for example there is a package missing that you think should be there. Is there no way to do that?

Therefore no partial upgrades is an Arch policy, not a pacman one.

It doesn't hurt to inform users of best practices. It's not like there is some other distro that uses pacman yet recommends partial upgrades.

I meant `-Syy` is not recommended, and `-Sy` is.

Wow, I completely misread this. https://wiki.archlinux.org/title/System … nsupported Sorry, everybody. This is what I get for having this conversation while in a meeting.

Alright, it's a pointless feature anyway. I'll just remove it.

@Alad I'd like to change the formatting to make it a little more clear. Is there a way to propose changes to the wiki page without actually making the change?

Yes, you can use the discussion page:

joehillen · 2021-09-02 19:06:39

Thanks. Kynikos's draft looks a lot like what I was going to suggest. I'm just going to submit and someone can reject it if they don't like it.

joehillen · 2021-09-02 21:55:38

I've removed `Ctrl-r`. https://github.com/joehillen/paruz/comm … 19409050de

Thank you everyone for you help. I learned a lot today.

Because pacman isn't only used on Arch or Arch-based systems. There are distros that use pacman where the partial upgrade issue doesn't exist because of the different configuration that they use for their repositories.

Arch Linux
