Standard library
This section is still a work in progress
The Aya standard library consists of type definitions, mathematical functions, string and list operations, plotting tools and even a small turtle graphics library. It also defines functions and objects for working with colors, dates, files, GUI elements, and basic data structures such as queues, stacks, and sets. The standard library also contains a file which defines extended ASCII operators for use when code golfing.
asciiart
Provides an asciiart datatype and several operator overloads for drawing complex ascii art pictures with only a few characters.
Run length encoding:
aya> " #` # #`5#"_
asciiart:

Operator overloads
aya> " #` # #`5#"_ T

color
The color library defines basic color constructors and conversions.
aya> 14 57 100 color!
(14 57 100) color!
aya> color.colors.violet :violet
(238 130 238) color!
aya> violet.hsv
[ 300 .45378151 .93333333 ]
aya> violet.hex

csv
Provides functions for reading and writing CSV files
aya> "examples/data/simple.csv" csv.read
{,
[
[ 1 2 3 ]
[ 4 5 6 ]
[ 7 8 9 ]
]:data;
nil:rownames;
[ "A" "B" "C" ]:colnames;
}
dataframe
The dataframe type is an interface for working with tables. CSV
files can be directly imported and modified or the data can be generated
by the program itself.
aya> {, [[1 2 3][4 5 6]]:data ["x" "y" "z"]:colnames} dataframe!
x y z
0 | 1 2 3
1 | 4 5 6
aya> {, [[1 2 3][4 5 6]]:data ["x" "y" "z"]:colnames} dataframe! :df
x y z
0 | 1 2 3
1 | 4 5 6
aya> df.["x"]
[ 1 4 ]
aya> "examples/data/simple.csv" dataframe.read_csv
A B C
0 | 1 2 3
1 | 4 5 6
2 | 7 8 9
date
The date script provides a basic interface for the date parsing
operators Mh and MH. It also provides basic date unit addition
and subtraction.
aya> date.now
May 01, 2017 12:53:25 PM
aya> date.now.year
2017
aya> date.now 2 dates.month +
Jul 01, 2017 8:53:42 AM
aya> date.now 2 dates.month + .mmddyy
"07/01/17"
enum
The enum library defines the enum keyword which uses
dictionaries and metatables to create enums.
aya> enum shape {circle triangle square}
aya> shape
shape
aya> shape :T
::enum
aya> shape.circle
shape.circle
aya> shape.circle :T
::shape
aya> shape.circle shape.circle =

golf
golf defines many short variables that are useful when golfing. It
also uses the Mk operator to add additional single character
operators. In the following code, all variables ì, ¶, ¦,
¥ and r are defined in the golf script.
aya> .# Generate and print an addition table
aya> 6r_춦¥
0 1 2 3 4 5
1 2 3 4 5 6
2 3 4 5 6 7
3 4 5 6 7 8
4 5 6 7 8 9
5 6 7 8 9 10
Sets default values for many variables
aya> [ a b c d k l p w z ì í]
[ 2 3 10 1000 [ ] 3.14159265 -1 0 {+} {-} ]
image
