Local compilation

How can I compile Sophia code the easiest to test Sophia scripts for correctness?

Is there an online compiler?

forgae compile contracts/ExampleContract.aes failed me with

===== Compiling contracts =====

I am guessing I need to be running a node then for compiling? What would be the most convenient way to get one running in that case & why would it be needed?


forgae node can get you a local node up and running. Then you can use forgae compile to try compiling your contract locally.

Thanks a lot. That’s a bit of overhead, VirtualBox, Docker, a node running, just to compile. There is no way to compile without all that?

It fails for me now with:

$ forgae compile contracts/ExampleContract.aes 
===== Compiling contracts =====

Here is version information, in case that helps:

 $ forgae --version


$ aecli --version


The fastest way for compiling and testing a simple smart contracts is via the contracts aepp or the playground

Here is a link to both of them : https://testnet.contracts.aepps.com, https://testing.playground.aepps.com.

About the forgae issue, are you sure that the node and compiler are up and running?


i tried installing forgae but got an error
