LispPad Go vs CodingKeys

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 networking, graphics, audio, databases, archival, text processing, etc. • Support for the Shortcuts app, allowing the execution of LispPad programs as standalone applications 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 extensible records • R6RS-compliant hashtables and enumerations • Threads

CodingKeys is a productivity keyboard to speed up typing code in iOS. Quickly type your code snippets in Notes, iMessage, or any iOS app by installing the custom keyboard extension in your Settings. Currently supported languages are Swift and Markdown, with more to be added in the near future! Hold down keys to select additional keywords and symbols. CodingKeys automatically switches back to your Alphanumeric keyboard when the context is expecting a normally-typed word. CodingKeys also moves the cursor smartly to the next place you should be typing when inside of closures, parens or conditionals.
