Re: [Maxima-discuss] qm-maxima package

[Daniel V. <dan...@ya...>]

 Hi Eric,
Thank you for your help. I changed the comment-out as you indicated. Now I am able to run the package.I am using qm-examples-1.wxm and I compare it with the original qm-examples-1.wxmx for reference.
I get the following output:
k: ket([a]); => ket([a])
b: bra([b]); => bra([b])b . k; => braket(bra([b]),ket([a]))
Not at all like the original:
k: ket([a]); => |[a]>
b: bra([b]); => <[b]|
b . k; => kron_delta(a,b)

What am I missing? Is it possible this depends on the commented-out packages?

This might be related to recent changes in Maxima regarding loading of
multiple index files. We developed a package template for third-party
packages (https://github.com/QMeqGR/PKG-maxima). Some changes were made
to core Maxima to be able to deal with multiple index doc files. These
changes are in the current development branch, but not in the last
release 5.47. (The 5.48 release is currently being assembled but I
don't know when that will be completed.) Until then you could clone the
Maxima repo from SourceForge and build Maxima to get the functionality,
or just use the PDF and text-based docs available through the "?" and
"??" functions.

The easiest thing to do is just comment out the loading of the index
files like you have below, but the way it is done is not quite correct.

To comment out code in a .mac file use the C-style /* ... */
delimiters. The Lispy ";;" comments won't work in a .mac file because
";" means 'end of input' to the Maxima parser.

Let me know how it goes.
