# bashify
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do not quote the array argument ( first agument )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
```
