About LispPad Go
LispPad Go is a simple, lightweight, integrated development environment for developing and running Scheme code on iOS. The language supported by LispPad Go is based on the R7RS standard of the Scheme programming language. LispPad Go provides the following components:
• A fully integrated Scheme interpreter
• A console with a read-eval-print loop to interact with the interpreter
• A text editor for writing Scheme code, supporting syntax highlighting, smart indentation, parenthesis matching, etc.
• A large range of libraries, including iOS-specific libraries e.g. for graphics, audio, databases, archival, text processing, etc.
The Scheme dialect supported by LispPad Go provides the following features:
• R7RS-compliant libraries
• Hygienic macros based on syntax-rules
• First-class environments
• call/cc, dynamic-wind and exceptions
• Dynamically-scoped parameters
• Multiple return values
• Delayed execution via promises and streams
• Support for the full numerical tower consisting of arbitrary size integers, rationals, real numbers, and inexact complex numbers.
• Unicode strings and characters
• Vectors and bytevectors
• Text and binary ports
• R7RS-compliant records
• R6RS-compliant hashtables and enumerations
• Threads
