Listing the functions defined in a package

Question

Assume that I know a package's (Context?) name that is loaded. Now I want to list the functions defined in this package. How can I do it?

I remember that I found a way once, but I cannot re-find it. I tried some combinations with ? but for vain.

Answer 1

Possibly this way:

<< PrimalityProving`

?PrimalityProving`*

or alternatively (see the copy&paste issue in the comments)

?"PrimalityProving`*"

See also the help under ref/Information, subsection "Generalizations & Extensions". In some cases you have to provide a string argument:

Information["*Values"]

Answer 2

Another possibility:

<< PrimalityProving`

Names["PrimalityProving`*"]

   {CertificateDiscriminant, CertificateK, CertificateM,
    CertificateNextPrime, CertificatePoint, CertificatePrime, fact,
    HilbertPolynomial, ModularInvariantj, PointEC, PointECQ,
    PrimeQCertificate, PrimeQCertificateCheck, ProvablePrimeQ}

Answer 3

I made a little interactive thing ('reportPackages') that often proves helpful. It lives in my own utilities package:

?? reportPackages

reportPackages::usage = "reportPackages produces a window with a SetterBar and a button. The SetterBar lists all currently linked Packages (from $Packages). The button produces a clickable list of exported Symbols of a selected Package. Clicking a symbolname gives its usage note if present ";

    reportPackages := 
  DynamicModule[{pakket, functies}, 
   Column[{SetterBar[Dynamic[pakket], $Packages, 
       Appearance -> "Row"], 
      Column[{Dynamic[functies = pakket <> "*"], 
        Button["info", 
         Information[Evaluate[functies], LongForm -> False]] }] }] // 
    Framed];
