Created May 24, 2018 15:58
Python implementation of matlab's `bwmorph` function for the operations:`thin`, `spur`, `bracnhes`, and `endpoints`
"""
Functions that implement some of the same functionality found in Matlab's bwmorph.
`thin` - was taken and adapted from https://gist.github.com/joefutrelle/562f25bbcf20691217b8
`spur` - Not perfect but pretty close to what matlab does via LUTs
`endpoints` - lines up perfectly with matlab's output (in my limited testing)
`branches` - this results in more clustered pixels than matlab's version but it pretty close

instaparse parser for prometheus text format exporter (text version 0.0.4)
(* see https://github.com/prometheus/docs/blob/master/content/docs/instrumenting/exposition_formats.md#text-format-details *)
statements = (type-def | help | metric)*
type-def = <"# TYPE "> metric-name <space> type <newline>?
type = #"counter|gauge|histogram|summary|untyped"
help = <"# HELP "> metric-name <space> docstring <newline>?
metric = metric-name labels? <space> value (<space> timestamp)? <newline>?
labels = <'{'> label-name label-value {<','> label-name label-value} <','>? <'}'>
(* the below doesn't take into account escaping but probably not an issue for our use case *)

sublist generator for clojure test.check... which has better shrinking properites?
;; my first version taking advantage of the new shuffle generator introduced in 0.6...
(defn sublist1
[coll]
(-> (gen/tuple (gen/shuffle coll) (gen/choose 0 (count coll)))
(gen/bind (fn [[coll* how-many]]
(gen/return (take how-many coll*))))))
;; version inspired by http://roberto-aloi.com/erlang/notes-on-erlang-quickcheck/
;; sublist(L0) ->
;; ?LET(L, [{E, eqc_gen:bool()} || E <- L0], [X || {X, true} <- L]).
