YAML (YAML Ain't Markup Language) is a lightweight data-interchange format.

The YAML package is a collection of commands for parsing YAML data into Maple expressions, and for encoding Maple expressions into YAML format.

Each command in the YAML package can be accessed by using either the long form or the short form of the command name in the command calling sequence.

The long form, YAML:-command, is always available. The short form can be used after loading the package.

The following is a list of commands available in the YAML package.

To display the help page for a particular YAML command, see Getting Help with a Command in a Package .

with(YAML):

ParseString("{ name: G Raymond, date: 2016年02月03日, payment: 50.71 }");

$table\left(\left[''name''=''G\; Raymond''\,''date''=''2016年02月03日''\,''payment''=50.71\right]\right)$

ToString( table([ "a"=[2,3,4,5], "b"=3 ]) );

$''---\; a:\; -\; 2\; -\; 3\; -\; 4\; -\; 5\; b:\; 3''$

The YAML package was introduced in Maple 2017.
