Write Scheme code on the go
Description (
Characters: 1263 of 4000

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. 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}

This is excellent software! For now it's the best way I found to program in Lisp on my iPad... It's free, open source, documented, based on standards, the UI is simple but user friendly...

This is, genuinely, my favorite app in the App Store. I'm moving to GrapheneOS soon and will be sad to be without it. (I realize it won't happen, but I would pay hundreds of dollars for an Android version. Seriously.) Thank you for all of your hard work in putting this together! It's so good.

Amazing app for practicing scheme on your phone! I appreciate it and recommend it! The only one thing that I would ask developer: please, if it’s possible and not too hard, add arrow keys to virtual keyboard, at least left and right ones.

are needed. And probably bug-reporter needs to be added. Except of that cool app, interesting one. And it works offline.

The user experience is perfect, the libraries more than enough and it looks good too!

Free and has version for the computer with sync. Ships with multiple libraries from scheme implementation used in the app. All documentation is available in the app in searchable menus or in PDF reference. The features that could be useful but are currently missing: - autocomplete; - search for variables and functions from libraries not yet imported into environment; - ability to export PDF language and library reference that are already stored within the app into files to use in reader of choice.

I mean, really, this is a fantastic thing: a Scheme with a competent editor, plenty of libraries. On an iPad. Oh, and the same environment also on a Mac, and you can share programs trivially. The future is, in fact, here.
