String

String typed values are a string i.e. an array of unicode characters

Strings...

• are immutable, i.e. assigning to an string results in a copy of the original string
• can be passed in/out of ops via string parameters
• can be initialized via string initialization
• are coerced according to string coercion

Initialization

String typed values can be constructed from a literal or templated string.

A templated string is a string which includes one or more variable-reference [string]. At runtime, each reference gets evaluated and replaced with it's corresponding value.

Initialization Example (literal)

i'm a string

Initialization Example (templated)

# JSON representation of in scope object "someObject", replaces $(someObject) in the string
# contents of in scope file "someDir/file.txt" replaces $(someDir/file.txt) in the string
pre $(someObject) $(someDir/file.txt)

Coercion

String typed values are coercible to:

• boolean (strings which are empty, all "0", or (case insensitive) "f" or "false" coerce to false; all else coerce to true)
• file
• number (if value of string is numeric)
• object (if value of string is an object in JSON format)
