-; APL Parser — right-to-left expression parser
-;
-; Takes a token list (output of apl-tokenize) and produces an AST.
-; APL evaluates right-to-left with no precedence among functions.
-; Operators bind to the function immediately to their left in the source.

-; AST node types:

-;   (:str s)                     string literal

-;   (:name "x")                  name reference / alpha / omega
-;   (:assign "x" expr)           assignment  x←expr
-;   (:monad fn arg)              monadic function call
-;   (:dyad fn left right)        dyadic function call
-;   (:derived-fn op fn)          derived function: f/ f¨ f⍨

+Files in this directory are pristine copies of upstream — do not edit them.

+- `tester.fr` — John Hayes' test harness (`T{ ... -> ... }T`). (C) 1995
+  Johns Hopkins APL, distributable under its notice.
+- `core.fr` — Core word set tests (Hayes, ~1000 lines).
+- `coreexttest.fth` — Core Extension tests (Gerry Jackson).
+
+Only `core.fr` is expected to run green end-to-end for Phase 3; the others
+stay parked until later phases.

+
+\ ------------------------------------------------------------------------------
+\ Version 0.15 1 August 2025 Added two tests to VALUE
+\         0.14 21 July 2022 Updated first line of BUFFER: test as recommended
+\              in issue 32
+\         0.13 28 October 2015
+\              Replace <FALSE> and <TRUE> with FALSE and TRUE to avoid
+\              dependence on Core tests
+\              Moved SAVE-INPUT and RESTORE-INPUT tests in a file to filetest.fth
+\              Use of 2VARIABLE (from optional wordset) replaced with CREATE.
+\              Minor lower to upper case conversions.
+\              Calls to COMPARE replaced by S= (in utilities.fth) to avoid use
+\              of a word from an optional word set.
+\              UNUSED tests revised as UNUSED UNUSED = may return FALSE when an
+\              implementation has the data stack sharing unused dataspace.
+\              Double number input dependency removed from the HOLDS tests.
+\              Minor case sensitivities removed in definition names.
+\         0.11 25 April 2015
+\              Added tests for PARSE-NAME HOLDS BUFFER:
+\              S\" tests added
+\              DEFER IS ACTION-OF DEFER! DEFER@ tests added
+\              Empty CASE statement test added
+\              [COMPILE] tests removed because it is obsolescent in Forth 2012
+\         0.10 1 August 2014
+\             Added tests contributed by James Bowman for:
+\                <> U> 0<> 0> NIP TUCK ROLL PICK 2>R 2R@ 2R>
+\                HEX WITHIN UNUSED AGAIN MARKER
+\             Added tests for:
+\                .R U.R ERASE PAD REFILL SOURCE-ID 
+\             Removed ABORT from NeverExecuted to enable Win32
+\             to continue after failure of RESTORE-INPUT.
+\             Removed max-intx which is no longer used.
+\         0.7 6 June 2012 Extra CASE test added
+\         0.6 1 April 2012 Tests placed in the public domain.
+\             SAVE-INPUT & RESTORE-INPUT tests, position
+\             of T{ moved so that tests work with ttester.fs
+\             CONVERT test deleted - obsolete word removed from Forth 200X
+\             IMMEDIATE VALUEs tested
+\             RECURSE with :NONAME tested
+\             PARSE and .( tested
+\             Parsing behaviour of C" added
+\         0.5 14 September 2011 Removed the double [ELSE] from the
+\             initial SAVE-INPUT & RESTORE-INPUT test
+\         0.4 30 November 2009  max-int replaced with max-intx to
+\             avoid redefinition warnings.
+\         0.3  6 March 2009 { and } replaced with T{ and }T
+\                           CONVERT test now independent of cell size
+\         0.2  20 April 2007 ANS Forth words changed to upper case
+\                            Tests qd3 to qd6 by Reinhold Straub
+\         0.1  Oct 2006 First version released
+\ -----------------------------------------------------------------------------
+\ The tests are based on John Hayes test program for the core word set
+
+\ Words tested in this file are:
+\     .( .R 0<> 0> 2>R 2R> 2R@ :NONAME <> ?DO AGAIN C" CASE COMPILE, ENDCASE
+\     ENDOF ERASE FALSE HEX MARKER NIP OF PAD PARSE PICK REFILL
+\     RESTORE-INPUT ROLL SAVE-INPUT SOURCE-ID TO TRUE TUCK U.R U> UNUSED
+\     VALUE WITHIN [COMPILE]
+
+\ Words not tested or partially tested:
+\     \ because it has been extensively used already and is, hence, unnecessary
+\     REFILL and SOURCE-ID from the user input device which are not possible
+\     when testing from a file such as this one
+\     UNUSED (partially tested) as the value returned is system dependent
+\     Obsolescent words #TIB CONVERT EXPECT QUERY SPAN TIB as they have been
+\     removed from the Forth 2012 standard
+
+\ Results from words that output to the user output device have to visually
+\ checked for correctness. These are .R U.R .(
+
+\ -----------------------------------------------------------------------------
+\ Assumptions & dependencies:
+\     - tester.fr (or ttester.fs), errorreport.fth and utilities.fth have been
+\       included prior to this file
+\     - the Core word set available

-;;    Requires lib/hyperscript/runtime.sx (provides hs-set-prolog-hook!)

-;;    No parser/compiler changes needed: Hyperscript compiles
-;;    `allowed(user, action)` to `(allowed user action)` — a plain SX call.
