Stuff (etl_core v0.1.55)
Useful functions
Summary
Functions
Converts a time in seconds to the understandable format hh:mm:ss
Takes the first elements of the list
Converts a number to a string, with the particularity that if the number is one digit, it adds the zero before it
Subtract between lists. It generalizes, and uses, the one implemented by Kernel.--/2. The difference is for when a term to "subtract" is a map; in this case its values are obtained and it is transformed into lists of tuples, applying the subtraction to them.
Generates a random string with the symbols '0123456789abcdefghijklmnopqrstuvwxyz'
Functions
convert_seconds_to_humans(time)
Converts a time in seconds to the understandable format hh:mm:ss
###Parameter:
- time: Integer. Time in second.Return:
- Stringget_firsts(list, n)
Takes the first elements of the list
Parameters:
- list: List. List.
- n: Integer. Number of elements to be taken consecutively, starting with the first.Return:
- {A, B} (A + B = list) where
A List the first `n` elements of `list`
B List of the remaining elements of `list`integer_to_string_with_2_digits(n)
Converts a number to a string, with the particularity that if the number is one digit, it adds the zero before it
Parameter:
- n: Integer. Number to convert.Return:
- String.list_subtraction(l1, l2)
Subtract between lists. It generalizes, and uses, the one implemented by Kernel.--/2. The difference is for when a term to "subtract" is a map; in this case its values are obtained and it is transformed into lists of tuples, applying the subtraction to them.
Parameters:
- l1: List of tuples of size 2. List of items.
- l2: List of tuples of size 2. List of elements used to compare in `l1`. Those tuples that are the same are removed from `l1`.Return:
- List of tuples of size 2random_string_generate(len)
Generates a random string with the symbols '0123456789abcdefghijklmnopqrstuvwxyz'
Parameter:
- len: Integer. Chain length.Return:
- String.
