The user writes blog entries by connecting to their remote image with sly/slime and
creates new entries by writing HTML using spinneret.

Definitions are sorted by export status, category, package, and then by lexicographic order.
ACCEPTOR - The acceptor you want to add this entry to, ie your instance of ’bloggy-acceptor.
ENTRY-CLASS - The class you want your blog entry to be, normally this would be your
own subclass of ’entry, this is used to determine the HTML and CSS that is generated and
allows you to maximize customizability.
CATEGORIES - This is a list of categories like (’general’ ’programming’), a category object
is searched for and if one cannot be found then one is generated for later.
Categories are found via that list, so a category is the product of its parents, and
their parents parents etc, this means that (’general’ ’programming’ ’lisp’ ’common lisp’)
and (’general’ ’programming’ ’common lisp’) do not resolve to the same category, however
they would both be children of the category ’programming’.
TITLE - The title for the entry.
SYM - A keyword used to reference this blog within CL.
DATE - Is a list that is passed to the function ’new-date-timestamp’ this accepts
keyword arguments that would be used with local-time:encode-timestamp in order to
generate a timestamp for that blog entry. This determines the order they are displayed in
both the index and the main page.
SUBTITLE - This is an optional subtitle.
DESCRIPTION - This is an option description. In the case this is provided then the RSS
feed will display this instead of the result of evaluating the function in content.
The description is also displayed on the index page.
LET-BINDINGS-TO-OVERRIDE-GLOBAL-VARS - This gives you an opportunity to per entry
lexically bind any of the global variables. Although I have not tested this so idk if
it works.
Given an ACCEPTOR (where your blog is stored), a path to an image (string)
and a KEY (keyword), creates a new instance of ’image-content and stores it within
the content object within your blog.
Returns all of the entries that are associated with CATEGORY within BLOG.
Attempts to find the category that is in list.
List contains the names of the categories, say (’general’ ’programming’ ’common lisp’
’generics’) the correct category would be the very final one, that is a child of
each of those categories successively, if you swapped ’common lisp’ for ’clojure’ then
the final category would have to be new. So categories are found by their parents.
Initializes the main blog within ACCEPTOR. This must be called before both new-index and new-content. BLOG-CLASS should ideally be a subclass of blog. Uses (url (make-instance BLOG-CLASS)) to determine the url to put the main page. Defaults to /blog/main.
Initialize the main content repo within (blog acceptor) using the class CONTENT-CLASS. Ideally CONTENT-CLASS will be a subclass of content.
Initializes the main index page within (blog acceptor) using the class INDEX-CLASS.
Ideally INDEX-CLASS will be your subclass of ’index. Uses (url (make-instance INDEX-CLASS))
to determine where to put the route for the index page.
Defaults to /blog/index

attempts to determine which subclass it should change-class that instance into.
Can possibly signal ’rss%bad-categories, ’missing-categories, ’missing-content
special-request)) ¶Displays the condition to the user.
WAY is a keyword argument, right now there are two :internal and :html,
:internal displays the condition as normal, while :html is used for rendering HTML for
the condition. If you look in src/generate-html.lisp you can see how the
request-conditions are formatted for HTML output

Converts object into RSS using xml-emitter.
entry)) ¶Generates the rss for an ENTRY object, fills in the default values and in the case that description is non nil then evaluates that function, if it is nil then evaluates the content function instead.
Attempts to handle a request to an unknown URI.
Tries to determine the type of request, which are subclasses of ’special-request.
Decodes the uri, checks it is valid and then creates the correct subclass.
All conditions that are a subclass of ’request-condition
are caught by :around and the conditions
are passed to display-condition with the :html key.
If a condition is a subclass of ’error a new condition is created and that is passed
to display-condition with the :html key.
If all goes well process-special-request is evaluated with the generated request.
Displays PAGE the correct way. If you wanted to change the layout
of a certain page, you would create a new version of html-body for your subclass of
that page. In that case it would be best to simply copy and paste the code for the
superclass and then play with it that way, you dont want to end up breaking functionality.

Generates CSS for page. Uses append method so that each subclass of
page has its CSS appended after. Works with most-specific-last meaning that the
methods are applied like so page -> entry -> my-entry, assuming you have subclassed
something and then created your own version of page-css for it. This is ideal for
CSS as CSS cascades. If you wanted to override the default colours you could create a
new :root and override the values of :–colourone etc.

content) (key (eql :upload)) &rest args) ¶Giving IM which is an instance of content, generates a url at ../generic/..
string) (key (eql :decode)) &rest args) ¶Decodes the URI string. Used when requests are made to tbnl. Makes use of *max-category-depth* in an attempt to stop DoS attacks which use very large URIs full of fake categories.
entry) (key (eql :for-route)) &rest args) ¶Default URI encoding for entries, this is so that entries once created can be
found at the correct uri. This is a workaround with Nginx, nginx seems to be rewriting URLs
so best just decode the URI on request and check that way.

The entry function used to create HTML pages. This method calls ’html-headers’ html-body’ and ’html-footer’ in that order in order to render a page. You can create your own version of this method to modify the functionality for your own subclasses the same goes for the three methods it calls.
