Non-Upwards Compatible Changes

<import:com.hp.donutLab.sliverServerPair>(..., timer :Timer, ..., ...)

IOU changes

Removed disposableKit#addCreationReactor/1, disposableKit#removeCreationReactor/1

TermL is now a superset of JSON

  • Y Dropping single-colon from the tag syntax.
  • Y Allowing an initial double colon.
  • N Allowing a quoted string as a segment. If it's the initial segment, we will also require that it be prefixed with a double colon.
  • N Changing the abstract syntax of a tag to use a list of arbitrary strings where it currently just accepts a single string by the above rules.
  • Y Dropping '=' from the current term-tree sugar syntax, and instead substituting ':', in order to be JSON-compatible.
  • Y from foo(.attr.(bar)) to .attr.(foo(bar))
  • Y pretty printing attributes
  • Y accept '//' comments,
  • Y accept '/*...*/' comments

The two ways in which the grammar defined here is not a subset of term.y is that grammar.y uses juxtaposition where term.y uses ',', and juxtaposition in grammar.y bind much more tightly than ',' in term.y. This allows the use of a more conventional bnf-like notation.

Parsed all examples on the JSON examples page. Detected that the third example is missing a close-curly.

LiteralChars

^LiteralString

DefineExpr and visitDefineExpr have a new optional field -- optEjectorExpr

? pragma.enable("trinary-define")

? escape foo { def `` := ("x", foo)}
# value: problem: Excess unmatched: x

New features

Draft new VatTP

Vat#isQuiescent()

Process#resultsVow()

makeCommand(...).exec(args, optEnv, oldDir, optStdinStr); fix __respondsTo/help

Brand#getNickName() :String

ControlLoop#waitAtTop(x :any) :any

"class" vs "interface" in eBrowser

unevaler#makePrintFunc() -> unevaler#getPrintFunc()

interp.setPrintFunc(timeMachine.getPrintFunc())

swtWatch(&x :EverReporter, varName :String)

UnQuote is now DeepPassByCopy

makeLamportSlot#fromSlot(slot, timer, delayMillis)

EverReporter, EverReactor vs rcvr[...]

Slot#isFinal() confusion; Slot#readOnly()

menuAction#makeMenu(parent :MenuItem, menuMap)

|"abc" vs ^"abc"

Bug: bnf "a b | c d" should parse as "(a b) | (c d)" but instead parses as "a (b | c) d".

Not done yet: From foo=bar expands to foo(.attr.(bar)) to foo : bar expands to .attr.(foo(bar))

Accepts foo::bar, but not yet ::foo nor foo::"bar"

termE__quasiParser

? def termE__quasiParser := <elang:syntax.termE__quasiParser>
