Utilities`Package`


The FindPackages function.

The functions in this package are for searching and maintaining Mathematica packages. FindPackages will give a list of the packages available, in their context form (e.g., "Utilities`Package`") or in a full path name form (e.g., "/usr/local/Mathematica/Packages/Standard/Utilities/Package.m".) You can specify a list of directories to search. You can also specify a string pattern, or a list of patterns, to be matched. Note that a pattern should not try to match the ".m"; the function handles this.

  • This loads the package.
  • In[1]:= <<Utilities`Package`

  • This gives all packages whose names end in "ca" for each directory in $Path. Directories containing no packages fitting the pattern give empty lists.
  • In[2]:= FindPackages[$Path, "*ca"]

    Out[2]= {{}, {}, {}, {DiscreteMath`Combinatorica`}, {}}


    Option for FindPackages.

  • Here the same search is performed, but full path names are returned.
  • In[3]:= FindPackages[$Path, "*ca",
    FullPath -> True]

    Out[3]= {{}, {}, {},
    {/usr/local/mathematica/AddOns/StandardPackages/
    DiscreteMath/Combinatorica.m},
    {}}


    The Annotation function.

    Mathematica packages contain various annotative comments tagged with keywords. The Annotation function allows you to discover what keywords are present in a package (or list of packages), then retrieve the actual annotation comments containing the keywords. This function recognizes a package name in either context form or as an explicit file name.

  • This finds the annotative keywords in the Utilities`Package` package.
  • In[4]:= Annotation["Utilities`Package`"]

    Out[4]=

  • The string "MathematicaVersion" is a useful keyword; it generally indicates the minimum release of Mathematica required for a particular package.
  • In[5]:= Annotation["Utilities`Package`",
    "Mathematica Version"]

    Out[5]=
