v0.19.0

Fixes re-evaluation logic for functions that close over values

v0.18.0

Changes:

• DictValue.keySet() is guaranteed to return a Set
• improved helpers creating Values from Objects

v0.17.0

The following features are added:

• decimals.from_double_exact allows to access the exact value of a double as decimal
• bin.of_'type' functions allow to construct blocks of binary data
• support for the decimal type in spec assertion functions
• math.finite? function checks for double NaN and -+Infinity

v0.16.0

This release introduces the exact decimal type decimal backed internally by a java BigDecimal

• decimal literals are written just like longs or doubles, with a d or D suffix setting them apart: 1.0d, 1e-3D, 1_000_000_D are all valid decimal numbers
• standard library functions such as math.min, math.abs, etc. are updated to correctly handle decimals
• dedicated decimals library for decimal-specific operations such as arbitrary precision division and scaling

v0.15.2

Changes in this release:

• added data.index_by function to std
• added data.omit function to std
• improve spec-runner to report tests skipped due to before hook or subject hook failure as failed

v0.15.1

Bugfix Release:

• fixes spec errors not propagating correctly up describe nodes
• fixes spec errors not displaying error location correctly

v0.15.0

New Features:

• compiler parses multiple files concurrently
• spec runner framework similar to mocha or rspec
  • standard library tested using test framework
  • support for host-application-provided side-effects in spec framework

v0.14.0

New features:

• Support for binary data type

• standard library includes functions working on binary data

  • converting to/from hex string representation
  • interpreting bytes as byte/word/dword/long/float/double
  • encoding/decoding base64

• Ability to specify resource load path for command line tools

  • this supports jars on class path that contain tweakflow code

• relaxed symbol key syntax: -,+, and / are now allowed characters

  • :content-type, :here/or/there, and :+foo+ are now valid keys

• allow _ to visually format long, double and binary literals

  • 10_000_000 is a valid long literal
  • 3.1415_9265_3589_7932 is a valid double literal
  • 0b_ABCD_0192__FDAB_0293 is a valid binary literal

v0.13.0

Unescaped keys need no longer be valid identifiers, and can start with digits.

:123 is now valid syntax

v0.12.0

New feature:

• Fast binary serialization designed for situations when values cannot be held in memory and need to spill over to disk
