Some notes scribbled over the last few months:
--11/07/20: ORAC enhancements (to investigate the FAST, aka Flat Abstract Syntax Tree):
-- Allow // as a line comment (as well as --)
-- Allow routine-level constant and static declarations (top only, some needed moving)
-- Added a hash() builtin offering partially compatibility with Euphoria
-- Added || and && bitwise operators along with ||= and &&= compound assignments
-- At the same time I added >> and << bit shift operators -- NB in Orac those were rotate.
-- Note that assert cond must be coded as assert(cond) [95 instances (6 already had the ())]
-- Likewise bitwise constant ==> enum by *2 [5 instances], and obj -> object [31 instances],
-- and a ''= b ==> xor_bits(or_bits(a,b),b) [5 instances, in orac that is, could do better?]
-- [note that enum by *2 does not allow general expressions, only compile-time literals.]
-- Also note that Phix has block scope whereas ORAC does not, so quite a few variables
-- had to be hoisted to routine-level rather than go out of scope at the (eg) "end if".
-- There were also a couple of places where I had to replace constant a,b with enum a,b.
-- While ORAC now runs on Phix, it is probably quite unstable, crashing with sq_op etc.
-- Note that "and" is a logical operator whereas && is bitwise, hence "1 and 2"=>1 (true) but "1 && 2"=>0, (=false).
-- Note that "or" is a logical operator whereas || is bitwise, hence "1 or 2"=>1 (true) but "1 || 2"=>3 (true-ish).
-- Short-circuiting is //not// performed by the && and || operators.
-- Migrate constants to block scope.
-- IupMglPlot, IupFlatFrame, IupDropButton, IupGLText, IupDatePick, IupFlatLabel, IupFlatList,
-- IupFlatSeparator, IupGauge, IupFlatToggle, IupFlatTree, IupFlatValuator, IupMatrixList,
-- IupSpace, IupMessageAlarm, IupMessageError, IupGlobalsDialog, IupClassInfoDialog
-- IupProgressDlg, IupMultiBox, IupFlatTabs, IupPostMessage, IupExecute, IupLog.
-- [also IupFlowBox, but IupMultiBox is probably better anyway]
-- added an optional limit argument to substitute()
-- new progress() routine - replace on rc when 0.8.2 is shipped
-- local constants and static variables in routines
-- static is now a reserved keyword
-- added bankers_rounding() routine
-- Icallbacki
-- dict_pop() and dict_peek() added
-- IupDestroy is now a function to encourage nullification of destroyed handles.
-- (nb this will break existing code, but the fixes should be obvious [or tmp/just {}= ])
-- builtins/unit_test.e (an autoinclude)
-- Work has begun in earnest on p2js. Do not get too excited just yet about the references to it
-- that have sprung up all over the docs - they are actually there to help me, not you, for now.
-- At this stage, feedback would probably impede, not help, thanks for the offer anyway.
-- db_current_table() added
-- peep_dict() and pop_dict() added
-- get_interpreter() is now an autoinclude
-- new requires() builtin
-- get_routine_info() now also returns the actual name
-- new hll_stubs.e
-- added mpz_xor(), mpfr_init_set_q(), mpfr_init_set_z(), mpfr_get_d(), mpq_cmp()
-- apply() enhanced to accept true/false as first argument, papply() addded.
-- factors(0) and prime_factors(0) now return {}, and is_prime(0) now returns false.
-- new sq_cmp() routine
-- shorten() what(aka 2nd arg) can now be ""
-- new is_integer()
-- added %q and %Q to printf(), along with prefer_backtick option
-- Edita/Edix:
-- Ctrl [] now copes with try statements
-- some nested comments were incorrectly handled (eg "--/* /**/ --*/")
-- Edix not found msg no longer spanners focus
Update: "static" removed in 1.0.1 (it only ever worked for integers and bools assigned to a literal or pre-existing file-level constant, and proved incompatible with p2js)
