The Slow Glass scripting language includes support for associative arrays. This is an advanced topic that is really aimed at programmers, who will find much of the syntax and usage here familiar.

Creating Arrays

Managing Individual Array Entries

Array variables are created just like normal variables but also include a key value:

(let | make) {variable-name}[{key-value}] be {value}

You can then access the array element in the usual fashion:

log ${my_var[key_string]}

Key values can be anything, including numbers if you wish, and they do not have to be contiguous.

You can also delete a single array value in a similar way:

delete ${my_var[key_string]}

Multiple Array Values

You can use a variation of the let / make command to make the lines following the command into array values. The first word on each of the next lines will be used as the key, the remaining words on the line will become the value. For example:

make phonetic from a able b baker c charlie ... z zulu endata

Will create an array variable that can be used like this:

text create message ${phonetic[a]}

And *message* will have the value “able”.

Array information

You can access information about an array by accessing its propertites:

${variable-name}.length

returns the number of items in the array (1 based).

${variable-name}.keys

returns the keys of the array as a single text, each key separated by spaces. There is no guaranteed ordering for the keys. If you want to step through an array you can use something like:

for key in $my_array.keys ` log ${my_array[$key]} endfor`

Similarly you can get a list of array elements with:
