Aura can't find libc++ even though it's an AUR package

[feroldi]

Running the following gives an error:

$ sudo aura -A libc++ libc++abi
aura >>= The following are not AUR packages:
libc++
libc++abi
aura >>= No valid packages specified.

Aura says libc++ and libc++abi aren't AUR packages. They actually are:

• https://aur.archlinux.org/packages/libc%2B%2B/
• https://aur.archlinux.org/packages/libc%2B%2Babi/

However, when I use the %2B encoded character instead of +, aura then is able to find those packages.

I had thought this bug already fixed, but sure enough it looks like the fix only applied to official packages and not for AUR lookups:

-- | If given a virtual package, try to find a real package to install.
resolveName :: MVar () -> Settings -> PkgName -> IO (Either PkgName (PkgName, Provides))
resolveName mv ss pn = do
  provs <- map PkgName <$> pacmanLines (envOf ss) ["-Ssq", "^" <> escape (pnName pn) <> "$"]
  case provs of
    [] -> pure $ Left pn
    _  -> Right . (, Provides pn) <$> chooseProvider mv ss pn provs
  where
    escape :: Text -> Text
    escape = T.foldl' f ""

    f :: Text -> Char -> Text
    f acc '+' = acc <> "\\+"
    f acc c   = T.snoc acc c

I'm going to call this a bug in the underlying aur lib and fix it there.

One should be able to just call info "libc++" naively and have it "just work".

Progress!

I'm able to build libc++ now.

This fix for this will be included in the upcoming release.
