taoensso.encore

Extended core library for Clojure/Script that emphasizes:

  • Cross platform API compatibility
  • Flexibility
  • Performance
  • Backwards compatibility

This lib's mostly for my own use and for advanced users that feel comfortable reading this source. Not providing much beginner-oriented documentation for this, sorry.

Quick Taoensso naming conventions: foo - Dynamic var foo! - Fn with side effects, or that should otherwise be used cautiously foo? - Truthy val or fn that returns truthy val foo!? - Fn that has side effects (or requires caution) and that return a truthy val. Note: !?, not ?! foo$ - Fn that's notably expensive to compute (e.g. hits db) foo_ - Dereffable val (e.g. atom, volatile, delay, etc.) foo__ - Dereffable in a dereffable (e.g. delay in an atom), etc. _ - Unnamed val _foo - Named but unused val ?foo - Optional val (emphasize that val may be nil) foo* - A variation of foo (e.g. foo* macro vs foo fn) foo' - '' -foo - Public implementation detail or intermediate (e.g. uncoerced) val

foo - Val "to foo" (e.g. >sender, >host), or fn to put/coerce/transform <foo - Val "from foo" (e.g. <sender, <host), or fn to take/coerce/transform ->foo - Fn to put/coerce/transform

Commit message tags (in priority order): ~ - Work-in-progress (still under development) [mod] - Modify behaviour (=> breaking), [mod!], [mod!!], etc. for attention [fix] - Fix broken behaviour (=> usu. non-breaking) [new] - Add new behaviour (=> non-breaking) [nop] - Unmodified behaviour (=> non-breaking implementation or non-code changes, etc.) [x][y] - Single commit with multiple tags (in priority order), try avoid

Provides a small, simple, flexible feature subset to alternative tools like clojure.spec, core.typed, prismatic/schema, etc.

;; Will throw a detailed error message on invariant violation: (fn my-fn [x] (str/trim (have string? x)))

Given a Unicode string, returns the normalized de/composed form.
It's often a good idea to normalize strings before exchange or storage,
especially if you're going to be querying against those string.

`form` is e/o #{:nfc :nfkc :nfd :nfkd <java.text.NormalizerForm>}.
Defaults to :nfc as per W3C recommendation.
