few helper functions in bash

#repeatString

repeats a string 

``` bash

repeatString string ?depth

#depth >> how many times to repeat the string

repeatString "bash" 5 # bashbashbashbashbash

```

#charAt

get the position of a character in a string

```bash

charAt string positionToSearch

charAt "bash" 2 # a

```

#includes

check if a word is in a string

```bash

includes string stringToSearch ?depth

#depth  where to start search from

includes "bash" sh 2

#returns 1 for false or 0 for true

```

#endsWith

check if a word is at the end of a string

```bash

endsWith string endToCheck ?depth

# depth >> where to start the search from

endsWith "bash" a 2

#returns 1 for false or 0 for true

```

#isInteger

check if a value is an integer

```bash

isInteger number

#return 1 for non integers or 0 for integers

```

#int

get all the integers before the decimal point

non integers values will throw an error

```bash

int number

int 25.8 ; # 25

```

#destructure

set the content of an array into different variables

gotchas

do not quote the array argument ( first agument )

it is important you quote the second argument to this function

          

associative arrays work in alphabetical order

          

use "," to separate the variables to assign each array element to

          

          

```bash          

destructure array values

array=( bash ksh zsh )

destructure ${array[@]} "shell1,,shell2"

echo $shell1  # bash

echo $shell2  # zsh

destructure ${array[@]} "shell1,shell2,shell3"

echo $shell1 # bash

echo $shell2 # ksh

echo $shell3 # zsh

```

#...

Spread a bunch of string inside an array

```bash

... string

str=bash

array=( $(... $str) )

echo ${str[@]} # b a s h

```

#foreach

foreach element of an array execute a function 

gotchas: 

don't quote the array arugment ( i.e the first argument )

If you pass in a function as a callback using the function command you should wrap it in single quote

```bash

s() { echo $(( $1 * $1 )) ;}

array=( 1 2 3 4 5 6 )

foreach ${array[@]} s # 2 4 6 8 10 12

foreach ${array[@]} 'function s() { echo $(( $1 + $1 )) ;}' # always end the function with a ;} 

# 2 4 6 8 10 12

```

#copyWithin

copy an array index into another index

quote the first argument use ${array[\*]} instead of ${array[@]}

```bash

copyWithin arrayArgument indexToCopyfrom indexToCopyTo

array=( "bash" "ksh" "zsh" "csh" )

copyWithin "${array[*]}" 1 3 # bash ksh zsh ksh

```
