brun '(a (i (q . 0) (q (x (q 1337) )) (q . 1)))'
gives:
FAIL: apply requires exactly 2 parameters (q)

I am trying to build an RPM from this but see no tar.gz file on pypi. Can you please upload the source tarball to pypi ?

warning: Downloading https://pypi.io/packages/source/c/clvm/clvm-0.9.6.tar.gz
curl: (22) The requested URL returned error: 404
error: Couldn't download https://pypi.io/packages/source/c/clvm/clvm-0.9.6.tar.gz

https://pypi.org/project/clvm/#files only shows a .whl file.

$python3 setup.py --help-commands | grep sdist
sdist create a source distribution (tarball, zip file, etc.)

so if you can first generate this sdist tar ball then upload it

In our workflow, we are using pep517.build (which is deprecated) to build the wheel:

Please add a version number in the setup() block in the setup.py file. This fixed issues when installed showing site-packages with -0.0.0- instead of -0.9.6- for the version.

setup(
name="clvm",
+ version="0.9.6",
packages=["clvm",],
author="Chia Network, Inc.",

from clvm import SExp

print(SExp.true) # This prints '01'

s1 = SExp.to((1, SExp.true))
s1.pair[1].atom = b'\2'

print(SExp.true) # This prints '02'

Probably should protect property by getter/setter.

Currently in clvm/more_ops.py,

def op_not(args: SExp):
    (i0,) = args_as_bool_list("not", args, 1)
    if i0.as_atom() == b"":
        r = args.true
    else:
        r = args.false
    cost = BOOL_BASE_COST
    return cost, args.to(r)

It seems if args is not an atom, not_op returns false and never raises EvalError.
Is this correct behaviour?

Given the following file: passwordprotect.clsp:

(mod (
        password_hash
        password
        receive_puzzlehash
        transaction_amount
    )
    (defconstant CREATE_COIN 51)
    (if (= (sha256 password) password_hash)
        ; true - password was correct
        (list
            (list CREATE_COIN receive_puzzlehash transaction_amount)
        )
        ; false - password was incorrect
        (x "Bad password")
    )
)

brun throws an error on my machine (windows 10, powershell:

brun '(a (q 2 (i (= (sha256 11) 5) (q 4 (c 2 (c 23 (c 47 ()))) ()) (q 8 (q . "Bad password"))) 1) (c (q . 51) 1))' "(0x9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 test 0xa11ce 1000)"

same brun command works on another machine (in the video tutorial and for another community member) :

File "/usr/local/lib/python3.8/unittest/loader.py", line 205, in loadTestsFromName
test = obj()
TypeError: run_program() missing 3 required positional arguments: 'program', 'args', and 'operator_lookup'

Are tests not wired/written for setup.py yet?

I noticed that if you have a parenthesis inside a quote in causes undefined behavior and the parenthesis is treated as if it is not inside a quote.

Example:
(if (> 10 5) ")" "(")

Causes output 41 when it should be ")"

Is there a way to generate safe random number securely in Chialisp?
Can this functionality be implemented based on VDF?

int_to_bytes at casts.py seems adding extra byte.

def int_to_bytes(v):
    byte_count = (v.bit_length() + 8) >> 3 # Should be (v.bit_length() + 7) >> 3
    if v == 0:
        return b""
    r = v.to_bytes(byte_count, "big", signed=True)
    # make sure the string returned is minimal
    # ie. no leading 00 or ff bytes that are unnecessary
    while len(r) > 1 and r[0] == (0xFF if r[1] & 0x80 else 0):
        r = r[1:]
    return r

Because of the above implementation, str(SExp.to(131)) returns 820083 as a serialized value, where 8183 is more byte-efficient.
(integer 131 is represented 83 as a hex string. Cleary this is 1-byte value.)
More directly, int_to_bytes(131) == b'\x00\x83' where b'\x83' is more byte-efficient
