I guess I'm puzzled with the different evmVersions and networks
understanding the differences between homestead, byzantium, constantinople, etc
byzantium
got it from the remix compilation details popup you told me, thanks :D
but now I think it's only backwards compatibility
been mistaken by an old article stating the mainnet ran homestead I guess
Hello . Folks I can't understand how to listen for the events in the solidity compiler 0.5.12 . the same is working if I change the version of solidity compiler to 0.4.X. I understand that there have been recent update in the ABI spec as well, but I can't understand what to change in the code to make the listening of the event work ?
it gives me errors.
I'm talking about listening for the events on the Java script side.
HI. You cannot read event from a smart contract. It is a write only channel. You can emit them, but you cannot read them in the EVM context. They are readable by the outer world only, I.e. by JavaScript based env realized on the front end. Anyway this is not the right panel where asking general questions: try to use stack exchange
@ynaciri I toggle the environment from JavaScript VM to Injected Web3, and get an error telling me I must have MetaMask active and running. This is not a browser, so I do not know where within this app to get MetaMask connected. I have a browser open, and it is connected, but somehow this Windows program also needs to see MetaMask. Perhaps the desktop version is solely for running JavaScript an via a localhost?
@Jshanks21 use ctr+ / ctr- or ctr mouse scroll
The compiler returned with the following internal error:
Uncaught JavaScript exception: RangeError: Maximum call stack size exceeded.
The compiler might be in a non-sane state, please be careful and do not use further compilation data to deploy to mainnet. It is heavily recommended to use another browser not affected by this issue (Firefox is known to not be affected).

Help me pls
truffle still makes strange bytecode compared to all the other tools but at least I found out my issue was the evmVersion
thanks for your time :)
@efalken my bad, did you get the popup for authorizing remix to communicate with metamask ?
I'm having problems using the provable oracle plugin on remix, it doesn't seem to be working. The provable developers submitted this issue ethereum/remix-plugin#145 since it seems the problem is on the remix side. Can anyone take a look please? Thanks.
I'm having a bit of trouble in the "Run" tab which I could do with some advice on
I'm logged into MetaMask on the Rinkeby test network, yet in the Run tab in Remix I cannot change the environment to Injected Web3 Rinkeby(4)... It is stuck on Injected Web3 Main(1)
Also, it does not recognise my accounts or let me add one
Any ideas?
@yann300 ugh, several. I thought it would be better than Chrome, and was for a while, but they are really pushing their new wallet and BAT token, which creates problems and generates many push notifications for services, etc. They clearly don't care about interfering with MetaMask, and presume everyone prefers their BAT token and stupid wallet.
Signature results have R and s, but without v, how can I get v?
function add(uint256 _a, uint256 _b)
pure
public
returns (uint256)
{
uint256 c = _a + _b;
assert(c >= _a);
return c;
}

}
I assume the browser can't handle large numbers...
