Some experiences for montezuma cl-markdown and cl-html-diff

I used these three libraries recently and want to write something down, :).

Montezuma

Montezuma is a full text index/search engine, What interested me is it has a port circle: Common Lisp -> Ruby -> Java -> Common Lisp, Why I can not use original version?

Montezuma offers a search-each method to search, but search-each only call a callback function to deal with search result, I have to mutate variables which violate function programming style. Another inconvenience is there is not a clean all index method, only a delete-document method. Besides it does not export get count of index method. I must use ::.

(montezuma::num-docs (montezuma::reader *wiki-index*))

cl-markdown

I use emacs-muse as mashup language of this post, however elisp is not popular, perl is, Markdown is a similar markup language written in Perl. I found cl-markdown as a Common Lisp port.

cl-html-diff

It is great Common Lisp always has library which I want to find. cl-html-diff generates a human-readable diff for html document, human-readable is provide two element del and ins, I do not know whether there are default style for them, I add two style to my css file.

ins{
    color: blue
    text-decoration: underline
}
del{
    color:red
    text-decoration: overline
}
