branch: externals/taxy
commit 247d473607fec8f42c9d2ad3326865f22c51324b
Author: Adam Porter <adam@alphapapa.net>
Commit: Adam Porter <adam@alphapapa.net>
Add/Change: taxy-take-keyed* -> taxy-take-keyed, key-fn chains
taxy.el should now have met feature parity with bufler-group-tree.el,
and also exceed it with the more flexible :take functions and other
features. It should now be a good foundation for these packages to
build functionality on.

+--------------------------------------------------------
+
+_Naming things is hard._
+
+ Going a step further, each element in the ‘taxy-take-keyed’
+function’s ‘KEY-FNS’ argument may be a list of functions (or a list of
+lists of functions, etc.), which creates a "chain" of "independent"
+dynamic taxys. Each such chain may be said to "short-circuit" the
+filling process in that, when an object is "taken" by the first key
+function in a chain, the object is not "offered" to other functions
+outside that chain. This allows each dynamic sub-taxy to have its own
+set of sub-taxys, rather than sharing the same "global" set. In effect,
+this creates multiple, unique taxonomies that share a single root taxy.
+
+ Building on the ‘sporty’ example, let’s define a taxy in which
+outdoor sports are classified only by whether they involve a disc, but
+indoor sports are additionally classified by whatever equipment they may
+use:
+
+ (defvar sporty-dynamic
+ (cl-macrolet ((in (needle haystack)
+ `(lambda (object)
+ (when (member ,needle (funcall ,haystack object))
+ ,needle))))
+ (cl-labels ((outdoor-p
+ (sport) (when (eq 'outdoor (sport-venue sport))
+ "Outdoor"))
+ (indoor-p
+ (sport) (when (eq 'indoor (sport-venue sport))
+ "Indoor"))
+ (disc-p
+ (sport) (if (funcall (in 'disc 'sport-uses) sport)
+ 'disc
+ 'non-disc)))
+ (make-taxy
+ :name "Sporty (dynamic)"
+ :take (lambda (object taxy)

+ (in 'ball 'sport-uses)
+ (in 'disc 'sport-uses)
+ (in 'glove 'sport-uses)
+ (in 'racket 'sport-uses)))
+ object taxy))))))
+
+ Now let’s fill the taxy with the sports and format it:
+
+ (thread-last sporty-dynamic
+ taxy-emptied
+ (taxy-fill sports)
+ (taxy-mapcar #'sport-name)
+ taxy-plain)
+
+ ("Sporty (dynamic)"

• Struct ‘taxy’ now has a ‘:make’ slot, a function called to make new
- sub-taxys by ‘take-take-keyed*’ (defaulting to ‘make-taxy’). This
+ sub-taxys by ‘take-take-keyed’ (defaulting to ‘make-taxy’). This
is useful when defining structs specialized on ‘taxy’.
• Struct ‘taxy-magit-section’ now has an ‘:indent’ slot, a number of
characters by which to indent each level of sub-taxy, applied
automatically by function ‘taxy-magit-section-insert’.
+ • Each element of the new ‘taxy-take-keyed’’s ‘KEY-FNS’ argument may
+ now be a function or a list of functions (or a list of a list of
+ functions, etc.). Lists of functions create "chains" of
+ independent, dynamic taxys descending from a single root taxy. See
+ *note example: "Chains" of independent multi-level dynamic taxys.
