Usual place http://phix.x10.mx/download.php (0.8.1 notes: https://openeuphoria.org/forum/m/134804.wc )

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)

UPDATE: (rather belated) It was, I believe, in this release that myfunc (without a following '(') became equivalent to routine_id("myfunc"),
and <int>(x,y,z) became equivalent (depending on context) to call_func/proc(<int>,{x,y,z}).

Hi Pete.

Thanks for the update - so far all win32 progs seem to be working.

As a discussion point, what is the best way to update your Phix installation? this time I just copied all the zip contents and overwrote the existing files, but doing this is it possible to leave some unused and possibly conflicting stragglers?

Cheers

Chris

With Linux 64-bit:

Testing[59]: /home/irv/phix/test/t64struct.exw 
 
/home/irv/phix/test/t64struct.exw:598 
attempt to divide by 0 

Testing[59]: /home/irv/phix/test/t64struct.exw 
[1;5,2] + 1/2   ->  [1;1,2,7,36600682685931650] 
 
/home/irv/phix/test/t64struct.exw:598 
attempt to divide by 0 

If I skip this test, all other tests pass.

Thanks, mea culpa, inadequately tested on 64-bit, I've simply changed it:

--for i=1 to length(dd) do 
for i=iff(machine_bits()=32?1:4) to length(dd) do

Ok, took me a bit longer than I expected, but I was in the middle of an IUP update, so finished that before installing phix 0.8.2.

All done now and tests all run, using my pre-installed IUP. Marvellous.

For info, I'm on IUP 3.30, CD 5.14, IM 3.15.

Hi Pete,

Thanks for the info. I downloaded 3.30 about a week ago.

I haven't checked the dates but a quick test in C and Phix seems to behave correctly.
I'll do a bit more digging tomorrow - dinner and wine imminent.

I can't get Phix to load .so files for pGUI.

How do you install Phix on Linux? Where does /Phix directory go? How do you get Linux to read p64 from any terminal?

be well

I don't know. I used sudo to mv /home/irv/phix/p /usr/local/bin (note: not p64, just p)

Now, from my home directory, I can type p hello, and run hello.ex.

However, if I add anything that needs to autoload a built-in (like open_dll), I get:

$ p hello 
"/home/irv" 
Cannot open autoinclude VM/pfileioN.e 
in /home/irv/, 
   /usr/local/bin/, 
   /usr/local/bin/builtins/VM/, 
or /usr/local/bin/builtins/. 

So p is looking in /usr/local/bin for the builtins folder. That is not where such things should be stored.

Euphoria libraries are in /usr/local/include which seems more reasonable.

I don't know how to change where p looks for the builtins.

Ok, strangeness...

... called from C:\Program Files (x86)\Phix\demo\pGUI\pdemo\installation.e:187 in procedure install() 

puts(1,"\n---  "&filename&"  ---\n")             
                download(filename) 

Is Phix cacheing code somewhere, and running from there if it wasn't deleted by a previous completed run?

I just added a with trace and a trace(1) and this was also ineffective.

So i went looking for a help file, or manpages, or a readme, or anything. Win7 won't open the .chm. On a whim, i tried and recieved....

C:\Program Files (x86)\Phix\pmsgs.e:564 in procedure Fatal()

I cannot get all the checks to be bold-grey. about half are lite-skinny-grey.

Same 404 in the same ole same ole. Waaaiiiitttt... RE-edited the installation.e, program is downloading.........

till it froze with

File C:\Users\user\phix.0.8.2.3.zip saved 
 
Delete downloaded zip files?(Y/N):N

What? Waasn't this self-hosted, self-compiling, and no need for any compiler knowledge?

I don't have any Visual Studio, and didn't consider wanting it, but must i get that now to get the libraries for it?

Good deal, that 200GB is already allocated for something else, and if program terminates normally, it will be full by mid Feb next year.

Woaaahhh... this addresses something i asked for in OE many many years ago, didn't get, and now use a preprocessor to make up for the absence of! Or what Donald Rumsfeld once said (paraphrasing) "we don't know what it is we don't know". People made fun of him, as if he had spouted nonsense (to be fair, he was long-winded), but he had finally told a logical truth.

The preprocessor can also make up for the lack of a come_from() (which is unrelated to the goto()).

But while it was originally only to control the access to an app's shared variables, it can now also know if it has a variable or function. Since it has access to it's var list, a subprogram (or the main control program) can save it's list, write out a different version of itself, abort() and restart, reload the vars, and resume with the function which was asked for. And know it.

But yes, speed is an issue. It's a big hit with the abort/run, but may be faster in the long run than a pure interpreter. I had hopes OE would eventually have a code block that could un/load OE source code and run it, as an interpreter, rather transparently to the programmer and outside world, like Greg's mention of re/loadable .il code. I suspect this was the promise of .dll code blocks, but oh well.

Equally wonderful hack, Pete!
