A library that supports two functions: push and pop. It is supposed to display the stack onto the page.

Added snippets to script-snippets, but given Ace's extremely sensitive tab completion...

Snippets currently consist of:
commands with OP_ removed (upper and lower case)
first three letters of substring after OP_ (if they are unique)
Symbols for arithmetic (+, /, etc)

E.g.:

OP_1 OP_NOTIF OP_3 OP_ENDIF

is marked as invalid, but I think it is allowed, e.g. with btcdeb:

./btcdeb '[OP_1 OP_NOTIF OP_3 OP_ENDIF]'

seems valid.

WIth OP_IF it is valid in both this project and btcdeb:

OP_1 OP_IF OP_2 OP_NOTIF OP_3 OP_ENDIF

Example script: aa OP_SIZE 1 OP_EQUAL seems to reset after executing OP_SIZE instead of pushing 1 to the stack. Similarly aaaa OP_SIZE 1 OP_EQUAL does not report script failure, it just resets.

Added keywords to script_highlighting_rules.js, but need to find where ctrl+space completion is resulting in lower case keywords

Consider the script 74686973697361736563726574 op_hash160.
Answer expected: 0x835ca4a6a1c2baaaf63bf33c777aff2fc681b017
Answer returned: 0xa69008fd5d7297bed5b71fea578a770e150b2f92

Expected behaviour confirmed at https://www.indicrypto.com/bitcointools/tool/pubkey-to-hash, https://bitcoinprices.org/public-key-to-hash/ and by running through the current master at https://github.com/kallewoof/btcdeb.

The error derives from mishandling the preimages as ascii instead of binary.
In PHP the hash() function returns ascii formed as hexadecimal. Thus:

php > echo hash('ripemd160', hash('sha256', '74686973697361736563726574'));
a69008fd5d7297bed5b71fea578a770e150b2f92

A correct implementation converts the preimages to binary first:

function hexStringToByteString($hexString){
  $len=strlen($hexString);
  $byteString="";
  for ($i=0;$i<$len;$i=$i+2){
    $charnum=hexdec(substr($hexString,$i,2));
    $byteString.=chr($charnum);
  }
  return $byteString;
}

function op_hashop160($preimage) {
  $preimage1 = hexStringToByteString($preimage);    
  $hash1 = hash('sha256', $preimage1);    
  $preimage2 = hexStringToByteString($hash1);    
  $hash2 = hash('ripemd160', $preimage2);
  return $hash2;
}

php > echo op_hashop160('74686973697361736563726574');

OP_SHA1

= not working

Had a few bugs reported; see:

https://twitter.com/grgiupaul/status/1002578263988981760

and https://twitter.com/grgiupaul/status/1002581114014306305

When I paste the SigScript + Locking Script for some transactions, it fails to correctly do the hash160 operation, for some reason.

Examples I found:

• P2PKH btc testnet: https://live.blockcypher.com/btc-testnet/tx/1eadc4a09c6abc8f024f04031334941ee455cd4fb112850788214da5f631a3d5/ (first output)

Complete assembly:

Generated hash160 is 089C63588D48F0BC16E13BD616D9F2F104E77AEC and it should be 7AB6EE8C168F32077C1CC83FACB49A91D7EE5DAE instead.

I don't have a clue why this is not working properly, maybe I am missing something? I don't think I am because the ASM code looks just fine.

OP_CHECKSIG always returns 01 (TRUE).

Hi

When I try to run a script with OP_Invert, the IDE fails.

How to reproduce: run script "f op_invert"

Output in console:

F
