ports: port peachpy go projects to avo

mmcloughlin opened this issue 7 years ago · 10 comments

Consider porting existing PeachPy Go projects to avo. At a minimum this would be really valuable feedback and system-level testing for avo. These could be committed to the avo examples directory or potentially committed back to the original repos if their maintainers are interested.

Porting my projects definitely on my TODO list. Start small then work big. Small are SPECK, marvin32, sip13. Maybe bloomindex. Medium are metro, chaskey, groupvarint. Large highway.

groupvarint not worth converting. Only a single tiny asm routine. Removed peachpy but left the generated 10-line function.

Answer 6 · 2019-03-18T18:21:04.000Z

Will probably not convert stadtx, as you've already done that.

Answer 7 · 2019-03-18T20:15:33.000Z

Will probably not convert stadtx, as you've already done that.

Please feel free to copy that code into your repo.

Notable in this one is the loop helper type.

type loop string

var loops int

func newLoop(name string) loop {
	loops++
         if name == "" { name = "loop" }
	return loop(name + strconv.Itoa(loops-1))
}

func (l loop) begin() string { return string(l) + "_begin" }
func (l loop) end() string   { return string(l) + "_end" }
