I am having issues on windows using the git bash terminal. Meep runs fine but the commands F3 F4 and ESC don't work.
Because of this I can't step through the stack, it's possible that this is an issue for al windows users.
If there is any quickk fix I'd love to hear it!
installation error "installing executables with 'go get' in module mode is depreciated", apparently since the release of Go 1.17
I've got the "Fail :( script exceeds maximum signature density" error message trying to debug the following tx e481e7179c7fb233bfa316482760987e40a643860d0f46abf0a0197819a6dfc8 in Bitcoin Cash mainnet
It would be a nice feature to have to display some text, possibly upon pressing some F button for help, that describes the function of the next opcode to be executed and the stack transformation to be expected.
The following command fails in meep on the final OP_CHECKSIG:
meep debug --idx=0 --amt=10200 --pkscript=a9148baa7f7c897382d277f6eb8a61e2666358364b2387 --tx=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
However, this is indeed a valid transaction and is on the blockchain at https://explorer.bitcoin.com/bch/tx/dbe0a2baa0857606375775fde2a89a6abaac204246ef0ccc13b9a776d0e0b3d7
When encountering OP_0 the program just display an empty line instead of the expected '0'
A valid script using bitcoin-abc regtest only succeeds sometimes with meep debug mode.
If it doesn't succeed then this is the error: Fail :( script exceeds maximum signature density
which is then followed by Fail :( past input scripts 3:0 3:xxxx
when hit F4 again.
It seems the script execution will only result with Success!!!
1/10 attempts.
Using the latest meep release, here's the debug command I'm using:
meep debug -t \
