Printing ANSI escape codes

I would like to be able to print colored output to the terminal using ANSI escape codes

"\033[31mHello Potion\033[0m" print

This currently outputs 033[31mHello Potion033[0m, not the desired 'Hello Potion' in red.

clang: error: argument unused during compilation: '-I core'

Trying to compile latest potion with clang and ccache produces this message:

CC core/potion.opic
clang: error: argument unused during compilation: '-I core'

It's because ccache is not yet fully clang-compatible, and it produces this warning, and you've requested by specifying -Werror in config.mak that all warnings be turned into errors.

In MacPorts we run into this kind of problem a lot, and recommend that you don't ship build systems that use -Werror, because you never know what kinds of new warnings will appear in compilers in the future.

potion_bytes_obj_string and other functions modifying unrelated data

Imagine if you added the following code between lines 43 and 44 of [http://github.com/orangea/potion/blob/1660fdf88bf9ee4cc8340187b28814aafb116681/core/file.c](This file):

printf("%lx\n", ((struct PNFile *)self)->path);
PN x = potion_byte_str(P, "");
printf("%lx\n", ((struct PNFile *)self)->path);
potion_bytes_obj_string(P, x, self);
printf("%lx\n", ((struct PNFile *)self)->path);

The printfs should always print the same thing, but they don't. I added those lines and then ran

File('a_valid_filename_here', 'r')

Here is the output on my computer:

100073870
2e4a226e0025000c
2e4a226e0025000c

Sometimes potion_bytes_obj_string will modify the data too. I think that this might have something to do with either a bug in file.c or the GC not handling the File class correctly.

test/closures/upvals.pn: expected <(function(), 17, 45, 67, 23, true, 16, (nil, nil), (b=2))>, but got <(function(), 17, 45, 67, 23, true, 16, (nil, nil), nil)>

The last argument gets lost

Getting 'block argument for to is not a closure' when using variables in a 'to' statement

b = 5
1 to b (x): x string print.
# ** block argument for to is not a closure

Fatal line in number.c

The code above should output 12345

Negative numbers

Potion does not handle negative numbers very well. Seriously, type -1 string or -1.0 string. _why was of the new wave school of childhood education... every child gets a trophy!

backport compiler and debugger support

add GC timings to -Dv

we want to know how many minor and major collections were done,
and how long they ran (in ms). overall and per run. maybe also print the stack size.

-DG is too verbose to check timings.

segfault in repl for non-period-ended phrases

Hey, built & all tests pass, but first run gives:

~/src/potion〉./potion
>> 5 times "hi" print
zsh: segmentation fault  ./potion

The correct code is 5 times: "hi" print, but this code should probably give a syntax or runtime error.

check if all docs are backported from p2

Am I missing something?

On both OpenBSD amd64 and Snow Leopard I get the following.

[james@thinkpad potion]$ ./potion                                                                                                                                                                                  
>> add = (x, y): x + y.
=> function(x, y)
>> add(2, 4) string print
nil=> nil

Is this expect behavior? I would think I would get 6 returned. All tests pass when I run make test yet calling a simple function doesn't?

The purpose of make's -w option is to print lines "Entering directory" and "Leaving directory" at appropriate times, which is sometimes nice to see when one is trying to understand a build system, but for some reason these are ending up in potion's config.h file, which is obviously invalid syntax in that context. Using make without the -w option seems to be fine.

darwin libuv rpath fixup needed

If there's no libuv.dylib found, darwin creates a libuv.dylib pointing to a -rpath /usr/local/lib/libuv.11.dylib, which is not installed.

Temp. workaround: sudo cp lib/libuv.11.dylib /usr/local/lib/

Integer range is probably lacking, but how do I cast/force a long/double in potion? I tried using the scientific notation, but to no avail.

Does not build on Snow Leopard

When building on Snow Leopard the following error is displayed:

'eval' has problems, parse is not GC safe

In potion, eval has some problems that make it behave strangely sometimes, such as that loop: 'x = Object()' eval. segfaults while 'loop: x = Object().' eval doesn't.

I think this is due to the fact that potion_eval calls potion_parse which overwrites data in the P variable. One way to overcome this problem would be to create a new Potion object in potion_eval, but that would require using potion_create/potion_init, which overwrites global variables like PN_string that are vital to the operation of the original Potion object. The only way I can think of overcoming this is to use fork in potion_eval.

fix PN_ALIGN_STACK

3d85fe1

Feature idea: a way to group expressions

Currently, there is no easy way to group expressions in Potion. To calculate 2 * (3 + 4), you have to type something like 2 * :3 + 4.() or 2 * (3 + 4)(0). There should probably be an easier way to do this, like surrounding the expression to evaluate first with a character (ex. /3 + 4/ or |3 + 4| or {3 + 4}). I think that they should be grouped with a : at the start and a ; at the end, like 2 * :3 + 4;. This syntax would be similar to the closure syntax.

allow verbose build output

Building potion produces output like this:

CC core/potion.opic

I want to see the full command that was used to compile the file. This is the usual way that make operates, but your Makefile goes to some lengths to suppress this, and provides no option to turn this suppression off.

Other projects offer the variable V which can be set to 1 to produce the usual verbose output, while setting V to 0 would produce the abbreviated output you're currently producing.

repl does not track locals: User-defined functions are always nil

I'm on OSX, and cloned down a fresh copy of Potion. Whenever I try to evaluate a function in the repl
like so:

>> add = (x, y):
    x + y string print.

>> add (1, 2)

It will always return nil. It's very strange, because if I monkeypatch (e.g. String length(): 10.), or load the built-in readline lib, it will work perfectly.

It seems native extensions will work, but not potion functions themselves.

By the way, I've running OSX Mountain Lion if that somehow makes any difference.

The way method calls are parsed is a little too complex and is prone to errors (ex. a = 5, b (a) :.)
Sometimes potion treats numbers as int when they should be treated as long.

Features:

Dynamic loader to load objective-c libraries and use the classes as potion classes.
Optional arguments
Errors
potion_get_caller() function to get a method's caller.

Big number division (overflow check in JIT?)

# true:
((10 / 2) == 5, "\n") join print

# Returns false, should be true
((60000000000 / 2) == 30000000000, "\n") join print
((60e+9 / 2) == 30000000000, "\n") join print
((60e+9 / 2) == 30e+9, "\n") join print
((60e+9 / 2) == 30e+9, "\n") join print
((60e+9 / 2e+0) == 30e+9, "\n") join print

Integer range is probably lacking, but how do I cast/force a long/double in potion? I tried using the scientific notation, but to no avail.

`to` segfaults when using a variable as the upper bound

Things work fine when using a variable as the lower bound, but Potion seems to segfault when using one as the upper bound. Example:

>> n = 3, n to 5 (i): i string print.
345=> 3
>> n = 5, 3 to n (i): i string print.
[1]    79643 segmentation fault  ./potion

Am I missing something?

Code points after \uFFFF

It seems that potion assumes that Unicode code points are 4 hex max:

    sromanov@killdozer ~/mydev/potion $ cat example/unicode.pn
    "I'm snowman - \u 2603\n" print
    "I'm bactrian - \u 1f42b\n" print

bactrian is printed wrong (not displayable here)

\u is sometimes defined to use exactly 4 chars, so I propose to use \U not as in python requiring exact 8 chars, but
in a relaxed way allowing 4 or 5 hex chars.
Theoretically one could also use 6 chars, but this range U+100000 - U+10FFFF (Plane 16 Private Use only)
is not used yet. So I got for 4-5 and take the 6th as char for the next symbol.

\U xxxx or \U xxxxx and if the 5th char is accidently a hex char but should not belong to the unicode char
it will be a incompatible change.

syntax.y:
escU = esc 'U' < hexl hexl hexl hexl hexl? >

The second possibility is to use \u with 4 or 5 chars.

perl gets this right (since 5.8.9, at least), since it has {} delimiters

    sromanov@killdozer ~/mydev/potion $ cat example/unicode.pl
    binmode STDOUT, ":encoding(UTF-8)";
    print "I'm snowman - \x{2603}\n";
    print "I'm bactrian - \x {1f42b}\n";

CFLAGS, CPPFLAGS, LDFLAGS ignored

I have supplied environment variables CFLAGS, CPPFLAGS and LDFLAGS when running the configure script, but when subsequently running make (without those variables set) they are ignored. The configure script should record their values somewhere so that the Makefile can use them at build time.

jit-x86: fix num of register limitation

On amd64 we could only address 15 local or upval vars via -n(%rpb),
on i386 max. 30 local or upval vars.

This limitation is now lifted by adding ASM_MOV_EBP() which checks
for the %ebp offset at compile-time and uses the word size insn if needed,
instead of the byte size insn before, which overflowed at 128.

#define ASM_MOV_EBP(op, reg)
  if (reg > 15) { ASM(op+0x40); ASMI(RBPN(reg)); }
  else { ASM(op); ASM(RBP(reg)); }

But it still doesn't work.

>> Object()
=> <Object a50f0>
>> Object()
=> <Object a5a78>
>> Object
=> Object
>> Object()
=> <Object a8640>
>> Object()
=> <Object a8fc8>

However,

while (Object != Object()):.

runs forever.
