Defines a configuration. The body CONFIGS contains multiple items,
with each following this pattern:
(name initial-value &optional docstring)
While calling this macro, all the given names, initial-values and
docstrings are evaluated during macro expansion.
Beneath the surface, DEFCONFIG actually generates the following stuff:
1. A variable *PROFILE*. It stores the current profile which is
desired to be a keyword.
2. A variable *CONFIG*. It stores the current configuration instance.
3. A class named CONFIG. Each item maps to a slot definition:
- name maps to slot name.
- initial-value maps to :initform argument.
- docstring maps to :documentation property of the slot.
4. A zero-arity inline function (and its setf version) for each
name. The function returns configuration value of current
profile. When the value itself is a function, it is called every
time and the value is returned. Otherwise, the value is directly
returned.
5. Some other helper functions and macros:
- with-profile
A typical example is:
(defconfig
(server-port 5001 "The server port.")
(app-dir "/tmp"))
Defines a profile with given NAME. CONFIGS is one or more lists,
with each following this pattern: (name value).
The evaluation rule of value follows DEFCONFIG.
It generates a variable *CONFIG-<NAME>* and a method SWITCH-PROFILE.
You may provide :before, :around or :after methods to SWITCH-PROFILE to insert some code.
Defines a closure to evaluate BODY for only once.
Convert given ITEM to CLOS slot. ITEM should be the a 2 or 3 length pair in config definition.
Make a keyword out of given string THING. The keyword is guaranteed to be upper case.
