NEO-GO Compiler

The neo-go compiler compiles Go programs to bytecode that the NEO virtual machine can understand.

The neo-go compiler is under very active development and will be updated on a weekly basis.

Currently supported

  • type checker
  • multiple assigns
  • types int, string and bool
  • struct types + method receives
  • functions
  • composite literals []int, []string
  • basic if statements
  • binary expressions.
  • return statements

Not yet implemented

  • for loops
  • ranges
  • builtins (append, len, ..)
  • blockchain helpers (sha256, storage, ..)
  • import packages

Not supported

Due to the limitations of the NEO virtual machine, features listed below will not be supported.

  • channels
  • goroutines
  • multiple returns

How to report bugs

  1. Make a proper testcase (example testcases can be found in the tests folder)
  2. Create an issue on Github
  3. Make a PR with a reference to the created issue, containing the testcase that proves the bug
  4. Either you fix the bug yourself or wait for patch that solves the problem
