The Phix Programming Language

phix's Issues

phix 1.0.2 download doesn't seem to be available

The download instructions for Linux indicate that phix can be downloaded using wget instructions like this:

wget http://phix.x10.mx/phix.1.0.2.zip
...

However, when I do this, I get a 404 error.

Strange Error when attempting to use 8.2

I downloaded 8.1 and installed it per the instructions on the website.

I then downloaded a zip of the git repo, unzipped it, named it Phix (8.1 Phix to Phix_old) and copied pw.exe from the old to the new (8.2) file, and used the installation instructions to recompile the compiler using the 8.2 source.

p -test ran fine.

when i go to do pw edita.exw in the proper folder, it fails with the following:

I am also including the text from ex.err as per the screenshot.
ex.txt

This also occurred when I tried to run manip.exw from the pgui launched with pw. Except it was with regards to int and not bool.

If i messed up in some way with my attempt to "update" to 8.2 I apologize for making this mess of a post.

Where I can ask Phix questions?

Hello there,
I have a couple of questions about Phix.
First: Can I run it on Mac M1 architecture?
Second: How small it can be? Memory footprint.
Third: Is there any Phix IRC channel or something?

weird memory violation

Hi,

I'm porting some old software and stumbled over a weird crash:

global function func1(atom man, atom ecc)
constant P2 = 2*PI;

atom m=man/360.0

m = P2*(m-trunc(m));

return m
end function

?func1(50.0, 0.9672725)

message is

...\test_bug.ex:12
(warning: lineno of -1 for era of #00685CEC)
fatal exception [MEMORY VIOLATION] at #00685CEC

it seems to crash on the m=P2* ... line ...

Version is 1.0.0 32 Bit on Windows

Greetings

Cross compilation?

I was wondering if there is any cross compilation support. For example, from Ubuntu Linux to Windows?

t42 failed

Hi,

t42 failed on Ubuntu 20.04, 64 Bit with Phix 0.8.3 - see below.

Show program output in edita pane

Is it possible to redirect the output of Phix programs to the lower edita pane?
The constant resizing and closing of terminal windows is annoying.
Thanks for your work!

A little mistake on "Readme" section

<<...For example if s="food" then s[2..3]="e" makes s "fed", and then s[2..1]="east" makes s "feasted".>> is wrong.

<<...For example if s="food" then s[2..3]="e" makes s "fed", and then s[2..2]="east" makes s "feasted".>> is correct.

problem with trace and function parameters

Hi again,

another interesting one:
I crashed with a traced source if I want to check a function parameter.

function with trace call:

1: with trace
2:
3: global function ellip(atom m, atom a, atom ecc)
4: atom k,e,c,s,fac,rho
5: atom x, y, vx, vy
6:
7: trace(1)
8==> k := KGAUSS / sqrt(a);
9: e := eccanom(m,ecc); c:=cs(e); s:=sn(e);
10: fac:= sqrt((1.0-ecc)(1+ecc)); rho:=1.0-eccc;
11: x := a*(c-ecc); y :=afacs; vx:=-ks/rho; vy:=kfac*c/rho;
12:
13: return {x, y, vx, vy}
14: end function

then I want to see 'm' with '?' ... this gives a crash ...

variable name? m

Tried to simplify the case with this code:

with trace

function p1(atom a, atom b)
atom c

c = a + b
trace(1)

return c
end function

?p1(2,3)

doesn't crash but the output for the variables is c = 3 b = 8589934592 a = 2

64 bit crash on Ubuntu with uninitialized vars

Hi again,

seems there are still several 64/32 issues. On Win32 the "variable not assigned" message comes nicely for the return statement, on Ubuntu64 we get a segmentation fault ...

Cheers
Otto

function p1()
atom a, b

a = 1
if false then
b = 2
end if

return {a,b}
end function

?p1()

seg fault with printing uninitialized string

Hi,

on Linux 64 Bit, Phix 1.0.1 if you have

string x
?x

you'll get a seg fault instead of a nice message ...

autoinclude ubits.e

Hi,

it seems that ubits.e is not autoincluded according to the manual (0.8.1).

Ubuntu upgrade: p executable doesn't work anymore

Hi,

the p executable 64bit V1.0.1 worked fine on Ubuntu 20.04.x. Yesterday I upgraded to Ubuntu 22.04 - the p executable crashes with a segmentation violation ...
