A module to generate a random string based on a given string pattern

The package can be installed by addingrandom_string_generator to your list of dependencies inmix.exs:

defdepsdo[{:random_string_generator,"~> 1.0.0"}]end

Usel for lower case letter from a to z

UseL for upper case letter from A to Z

Used for digit from 0 to 9

Usep for punctuation

Usec for custom character

!,",#,$,%,&,',(,),*,+,,,-,.,/,:,;,<,=,>,?,@,[,\,],^,_,{,|,},~ and`

iex>RandomStringGenerator.generate("lldd")"ol68"

iex>RandomStringGenerator.generate("LL")"VR"

iex>RandomStringGenerator.generate("pp")"?!"

Delimiters

Everything that is notl,L,d,p andc is treated as a delimiter sothe pattern-dl? is interpreted as a hyphen followed by a digit followed bya lower case letter followed by a question mark.

iex>RandomStringGenerator.generate("ll-")"yz-"

Scape

In order to generate a string containing the charactersl,L,d andpas a delimiter, you need to use the backslash twice in order to scape it.

iex>RandomStringGenerator.generate("dd\\l\\L\\d\\p")"39lLdp"

Custom Chars

I order to generate a string based on a given custom patternccc a listof possible values need to be passed as an argument.

iex>RandomStringGenerator.generate("ccc",["+","-","/","*"])"+/*"

If no custom char list is passed the with characterc it will be treatedas adelimiter as in the example below where it generates a string containingone digit followed by the letter c followed by another digit

iex>RandomStringGenerator.generate("dcd")"2c1"

Shuffling

In order to generate a string based on a given patterLldd where thosecharacters are placed in a random order, theshuffle/1 function shouldbe used.

iex>RandomStringGenerator.generate("Lldd")|>RandomStringGenerator.shuffle()"s22E"
