UsefulGo

Get Started

import (
    uf "github.com/ac5tin/usefulgo"
)

Array

ArrContains

// ArrContains check is array contains a string
containstring := uf.ArrContains(arrstring,str)

ArrRMS

// ArrRMS removes string element from array (ordered)
uf.ArrRMS(&arr,str)

ArrRMiF and ArrRmiS (remove array elemet by index (fast and slow))

• ArrRmiF (Fast array index remover but doesnt maintain order)
• ArrRmiS (Slow array index remover but maintains order)

NewArrRmiF().String(&stringarr,3)
NewArrRmiS().Int(&intarr,3)

Binary

GetBytes

// GetBytes returns binary byte slices
byteslices,err := uf.GetBytes(x)

CSV

CSVParser

// CSVParser parses csv and runs callback function
reader := bytes.NewReader(byteslice)
r := csv.NewReader(reader)
err := uf.CSVParser(r,func(res []string,chunk int){

})

CSVParserH

// // CSVParserH parses csv with headers and runs callback function
reader := bytes.NewReader(byteslice)
r := csv.NewReader(reader)
err := uf.CSVParserH(r,func(res []map[string]string,chunk int){

})

Hash

HashPassword

// HashPassword returns hashed version of password
hashed,err := uf.HashPassword(pw,cost)

CheckPasswordHash

// CheckPasswordHash compares hashes between password string
cmp := uf.CheckPasswordHash(pw,hashed)

Mapfields

// Mapfields - returns subset map

mf := uf.Mapfields(d, fields) //d is of type map[string]interface{}

Hashmap

// Hashmap hashes a map using sha256 and returns the hash as string
mfhash, err := uf.Hashmap(mf)

Random

RandString

// RandString generates random string
rnd := uf.RandString(5)

String

RmDash

// RmDash removes dashes from strings
newstr := uf.RmDash(oldstr)

UUID

GenUUIDV4

uuid := uf.GenUUIDV4()

Math

IntAbs

x := -5
absx := uf.IntAbs(x) // returns 5

Compression

Compress, Decompress

NewCmpr().Compress(data,"xz") // gz for gzip, xz for LZMA2 xz
NewCmpr().Decompress(data,"xz")

Parsing

NumParse, FloatParse

NumParse[int64]("123") // parse string to int64
FloatParse[float32]("1.12") // parse string to float32
