  • Give frozen js objects value-based hashes, other objects get identity (incrementing) hashes

  • Mak type also lookup the constructor on functions (for Keyword etc)
  • DOM API: rename query to query-one (vs query-all)

0.0.23 (2023-07-14 / 6bf6d0)

Changed

  • bin/piglet tweaks

0.0.21 (2023-07-14 / 9bda98)

Changed

This is a pretty big release, some highlights:

  • dev-server for much easier onramp when doing webdev
  • source maps support (in the browser, if the source-map library is present)
  • add syntax-quote (backtick)
  • compile directly to JS operators (unary and binary, e.g. +, and, not) if possible, while falling back to the function version, e.g. when used in higher order functions
  • added reduced for short-circuiting reductions
  • significant performance improvements
  • add sets (#{})
  • makes sets and dicts callable
  • much improved sequential destructuring
  • support unicode codepoints in string ("\u{1234}"), including higher-plain ones
  • add --eval / -e flag to piglet script
  • Nodejs 17 support (before we required at least 18)
  • Add completion support to pdp-client.el (see also the counterpart of this in pdp.el)
  • Make TypedArray (e.g. Uint8Buffer) and ArrayBuffer seqable, and make them print nicely
  • toJSON support in collections, so you can call JSON.stringify on them
  • DOM wrapper API
  • Allow a bare symbol as an import
  • Specifying a package id is optional (will use URI derived from package location)
  • Interop improvements: keyword lookup for plain JS objects, ->pig/->js lazy nested conversions (still lots of thinking and improving to do around interop)
  • Lots of additional core API: ->js ->pig apropos apropos boolean? constantly defmethod defmulti defonce doto drop empty? ffirst fnil fqn frequencies get-in hash-code hash-combine identifier? juxt keep max merge min not= object? oget okeys oset ovals rand-int rand-nth reference repeatedly reset! run! sort take type-name undefined? vector vector?

Added

  • load-package as shorthand for (.load_package *compiler* ...)

  • QName: retain suffix/prefix info when expanding from PrefixName
    • useful for XML namespace handling
  • Default context: add SVG xml namespace
  • Async versions of reduce and for: (for ^:async [...] ...) -> can use (await) in the body, and returns a promise of a sequence

Fixed

  • Import of js packages with an '@' in their name
  • Allow destructuring in doseq/for
  • Multi-arg boolean operators (e.g. (< 1 2 3))
