password-generator is command line interface app to generate random password. This app can be used to generate any random text from provided rules.

requirement

Should have go installed. Go can be downloaded from here.

or

make build

• check if successfully build

./pwd-gen version

• generate random text
  • without rules(copies text to clipboard)

./pwd-gen g

- with rules

./pwd-gen g --numbers=7 --symbols=2 --down=2 --up=3 --copy=false

or

./pwd-gen g -n=7 -s=2 -d=2 -u=3 -c=false

• help?

./pwd-gen help

Available Flags

Flag	Short	type	Default value	Meaning
symbol	s	number	0	number of symbols to generate in return text
up	u	number	4	number of upper case letters to generate in return text
down	d	number	3	number of down case letters to generate in return text
number	n	number	0	number of numerical digits to generate in return text
copy	c	boolean	true	copy generated text to clipboard.If set false then prints text in console itself

Package usage

This package can also be used as common library to generate random text from provided text rule. text.TextBuilder implements text.Builder interface which include following two function to help build text rule

• AddRule(TextRule) Builder
• Build() (Generator, error) Also text.text implements text.Generator interface which allows us to generate text
• Generate() string

Sample code usage:

  import(
    "github.com/shankar524/password-generator/src/text"
  )
  // create textBuilder
  textBuilder := text.TextBuilder{}
  textBuilder.AddRule(text.TextRule{For: text.LOWERCASE, Length: 6})
  textBuilder.AddRule(text.TextRule{For: text.NUMBER, Length: 2})
  textBuilder.AddRule(text.TextRule{For: text.UPPERCASE, Length: 2})
  textBuilder.AddRule(text.TextRule{For: text.SYMBOL, Length: 2})

  generator, err:= textBuilder.Build()
  if err!= nil {
    fmt.printf("error creating text generator. Error: %s", err.Error())
    return
  }

  fmt.Print(generator.Generate())

  // generate default generator
  defaultBuilder := text.TextBuilder{}
  defaultGenerator, _ := defaultBuilder.Build()
  fmt.Print(defaultGenerator.Generate())
