#16713 — HeaderInformation[] function is gone

Hi,

As far as I remember, until version 6, the function

HeaderInformation[=93Contextname`packagename`=94]

Returned the package-header information as, :Context: , :Title:, :Author:,
:Package Version:, :Mathematica Version:, :Copyright: , :History: ,
:Summary: , :Keywords:, :Contents:, :Discussion: , :Sources:, :Warning.

I think that in newer versions, after V6,  it has been removed. The
Mathematica Version advisory in version 6, still accepts
*HeaderInformation[]* as compatible code coming from earlier versions, but
now in V8, neither it appears in the Help nor is executed at all.

Am I wrong?

E. Martin-Serrano

This function was probably part of the package mentioned here:

http://mathematica.stackexchange.com/a/699/12

The package is not part of Mathematica any more but it can still be 
downloaded from the Wolfram Library Archive.

#16720 — Re: function is gone

Thanks Szabolcs,

In fact, today the whole thing seems to work the following way

In[1]:= Needs["Utilities`Package`"]

(* functions - names- in "Utilities`Package`" *)

In[2]:= Names["Utilities`Package`*"]

Out[2]:= {"FindPackages", "FullPath", "PackageInformation"}

(* Looks up the HeaderInformation in the package "myContext`myPackage`"*)

In[3]:= PackageInformation["myContext`myPackage`", PackageInformation["myContext`myPackage`"]]

Out[3]:=  (* All info in the header of "myContext`myPackage`". Including  "Context", "Title", "Author", "Package Version", "Mathematica 
Version", "Copyright", "History", "Summary", "Keywords", "Contents",
"Discussion", "Sources", "Warning", "Last modification", and so on*)

Off topic comment

The actual package belongs to a large application that I wrote in 2002, which makes heavy use of Combinatorica. I am having a hard time in recovering (and revamping) it after 10 years, to make it work in the newer versions. Among other difficulties: the whole old fashioned documentation and Help is nearly unusable.

Thanks again.

E. Martin-Serrano
