Boyer moore impl in go re: https://leetcode.com/problems/implement-strstr

	func strStr(haystack string, needle string) int {
	foundpos := -1
	if len(needle) < 1 {
	return 0

go reverse

	package main

	import (
	"fmt"
	"reflect"
	)

	func reverse(slice interface{}) interface{} {
	/* Completely inefficient but syntactically "convenient" */
	s := reflect.ValueOf(slice)

polynomialspace / optional.go2

Created June 25, 2020 03:31

Attempting to do optional type stuff in Go2 and doing a terrible job at it

	package main

	import (
	"fmt"
	)

	type Optional(type T) struct {
	p *T
	}

polynomialspace / TokenActor_test.go

Last active December 29, 2020 19:31

WIP-y POC emulating the actor model in go. This snippet is intended to be implemented later in a larger project with a specific usecase after further modification.

	package main

	import (
	"testing"
	"time"
	)

	type TokenRequest struct {
	Key string
	Value string

polynomialspace / gobmarshal.go

Created February 26, 2021 11:14

similar marshal/unmarshal functions as other encoders for gob

	func gobMarshal(v interface{}) ([]byte, error) {
	var buf bytes.Buffer
	enc := gob.NewEncoder(&buf)
	err := enc.Encode(v)
	return buf.Bytes(), err
	}

	func gobUnmarshal(data []byte, v interface{}) error {
	dec := gob.NewDecoder(bytes.NewReader(data))
	return dec.Decode(v)

polynomialspace / NDjsonTojsonArr.go

Last active March 24, 2021 05:40

ndjson -> json array (technically golang will take '\n' as a json sep where ndjson is '\r\n' but /shrug)

	// NDjsonTojsonArr converts newline-delimited json (indented or minified)
	// to a json array. Caller should handle cleanup on error.
	func NDjsonTojsonArr(r io.Reader, w io.WriteCloser) error {
	w.Write([]byte("["))

	var m json.RawMessage
	dec := json.NewDecoder(r)
	err := dec.Decode(&m)
	for {
	if _, err = w.Write(m); err != nil {

polynomialspace / asconv.go

something about asdot idk

	package main

	import (
	"fmt"
	"strconv"
