0.19.0

  • Fix: Zero passed to Date:year family functions ignored
  • Fix location informations in syntax errors and others
  • arr.reduce now throws a distinct error when called with an empty array and no second argument
  • Add str.pad_start,str.pad_end
  • Add arr.insert,arr.remove
  • asynchronization of arr.sort for better processing speed
  • Add arr.flat, arr.flat_map
  • Add Uri:encode_full, Uri:encode_component, Uri:decode_full, Uri:decode_component
  • Add str.starts_with,str.ends_with
  • Add arr.splice
  • Add arr.at
  • For Hosts: With an error handler, Interpreter now do the abortion of all processes only when abortOnError option is set to true

0.18.0

  • New function Core:abort for immediate abortion of the program
  • Add array version of index_of
  • str.index_of and arr.index_of now accept a second argument
  • Remove type restriction on the argument for arr.incl
  • Add Date:millisecond
  • Add arr.fill, arr.repeat, Arr:create
  • Destructuring assignment available, like JavaScript(but limited functionality now)
  • Amend the error message on duplicated declaration of variable
  • Variables under nested namespaces are now accessible
  • Add arr.every, arr.some
  • Add Date:to_iso_str

0.17.0

  • Fix package.json
  • New function Error:create to create a error-type value
  • New function Obj:merge to get a merge of two objects
  • Fix: Chainings([] for index access, . for property access, () for function call) used in conjunction with parentheses may cause unexpected behaviour
  • New functions: Str#charcode_at Str#to_arr Str#to_char_arr Str#to_charcode_arr Str#to_utf8_byte_arr Str#to_unicode_codepoint_arr Str:from_unicode_codepoints Str:from_utf8_bytes
  • Fix: Str#codepoint_at not supporting surrogate pairs
  • IndexOutOfRangeError now also occurs when assigning non-integer index or outside boundaries of arrays

Note

CHANGELOG had a missing record in V0.16.0.

  • Add new functions Str:from_codepoint Str#codepoint_at

0.16.0

  • Namespaces can no longer include var (while let is available as it has been)
  • Core:to_str and template syntax can now convert any type of values into string
  • Add Core:sleep: waits specified milliseconds
  • New syntax: exists <variable-name> can judge specified name of variable actually exists in runtime
  • Object values can be now referenced via index (ex. object['index'])
  • New value type: Error Type (type name: error)
  • Json:parse now returns error-type value when parsing failed
  • Fix: Variables defined with let is yet mutable
  • Add new functions Str:from_codepoint Str#codepoint_at

For Hosts

  • Breaking Change Subclasses of AiScriptError now have AiScript- prefix (ex. SyntaxError→AiScriptSyntaxError)
  • Interpreter's second constructor argument now accepts err option: pass a callback function to be called when Interpreter.exec fails or Async:interval/Async:timeout fails. Noted that using this feature disables AiScript process from throwing JavaScript errors.
  • Native functions can use opts.topCall instead of opts.call to call error callback when failing like two functions above. Use only when necessary. If opts.call calls error callback correctly, use that.

0.15.0

  • Enrichment of Math:
  • Fix: Terms of operator &&, || may not be converted correctly

0.14.1

  • Fix: Short-circuit evaluation of &&, || is not working correctly
  • Fix: operator +=, -= may overwrite unrelated variable

0.14.0

  • Add Obj:vals that returns an array of values of given object
  • Add Json:parsable that judges whether given string is parsable with Json:parse
  • When first argument of or/and determines the result, now second argument is no longer evaluated
  • Fix immediate value check in Async:interval

0.13.3

  • Random number generation now includes specified maximum value in returning range

0.13.2

  • Date:year,Date:month,Date:day,Date:hour,Date:minute,Date:second are now accepting a number argument to specify the time
  • Add array.sort and comparison functions Str:lt, Str:gt
  • Random number generation now includes specified maximum value in returning range

0.13.1

  • Fix: Json:stringify returns corrupted value when given functions as argument

0.13.0

  • Index arguments for callbacks of some array properties are now zero-start: map,filter,reduce,find
  • Add @Math:ceil(x: num): num
  • Exponentiation function Core:pow and syntax sugar ^
  • Minor fixes of parsing

0.12.4

  • block comment /* ... */
  • Math:Infinity

0.12.3

  • Fix: break/return does not work in each statement
  • IndexOutOfRangeError now occurs when accessing outside boundaries of arrays

0.12.2

  • Logical Not operator !
  • Adjustment of interpreter processing speed

0.12.1

  • Single quotes are now available for string literal
  • Fix: return does not work in for/loop statement
  • Runtime now constantly pauses a few milliseconds to prevent infinite loops from causing runtime freezes

0.12.0

Breaking changes

  • # for variable definition → let
  • $ for variable definition → var
  • <- for assignment → =
  • = for comparison → ==
  • & → &&
  • | → ||
  • ? ~ .? ~ . → if ~ elif ~ else
  • ? x { 42 => yes } → match x { 42 => yes }
  • _ → null
  • << → return
  • ~ → for
  • ~~ → each
  • + attributeName attributeValue → #[attributeName attributeValue]
  • Removed +/- notation for truth values.
  • for and each no longer return an array
  • Block statement { } → eval { }
  • Arrays are now indexed from zero
  • Some std methods are now written in property-like style:
    • Str:to_num("123") -> "123".to_num()
    • Arr:len([1 2 3]) -> [1 2 3].len
    • etc
