Built in Emacs is decent, but I can’t figure out the how or where the Meta key is. Any help appreciated on that problem, otherwise, a very good solution for Lispers and Schemers without access to a full computer. ### 3/5 — Needs to be fixed using BlueTooth keyboard *2019-02-07* Please fix the bug in the BlueTooth keyboard where it sees a double quote as some UTC code other than the double quote. It is not convenient to use the onscreen key to quote strings when using a keyboard. I have the Logitech Logi keyboard. ### 3/5 — Helpful keyboard but otherwise disappointing interface *2018-01-21* The custom keyboard that comes with this build of gambit-c is very useful, making most needed keys readily available. However, the file editor is rather awkward and basic, and the REPL is far more primitive than what comes with PC builds. If you want to try the Scheme language on your desktop or laptop, definitely try out Gambit; it is one of the most well known and mature implementations and has a great interactive REPL. This mobile version was disappointing. ### 4/5 — Good utility for schemers *2017-04-13, version 7.1* I use and like gambitc on the desktop and find the REPL useful to address ad hoc problems on an iPad when away from desktop. It also serves as a fantastic high precision calculator. ### 5/5 — Fixed: iOS 6 *2015-03-10, version 7.1* Thanks for the iOS 6 fix ... it seems fine now ... much appreciated. MichaelG. _________ Previous review; for reference only: Totally dysfunctional "update" App no longer opens on my iPodTouch. ### 5/5 — Fixed *2015-02-17* This new release has fixed crashes on 64bit devices. It now works great on my iPad. Thank you. ### 1/5 — Non functioning app *2015-02-11, version 7.0* Latest update 5th Feb 2015 does not load using iOS 7.1.1! ### 5/5 — Broken on iOS 8 *2015-02-06* Unfortunately the 7.0 update no longer runs in iOS 8. The app crashes immediately upon opening on both an iPhone 6 and iPad Air 2. Looking forward to seeing the new features-- hope an update is quickly forthcoming! ### 3/5 — Some annoying oddities *2014-12-01, version 6.2* It basically works, but... why are you allowed to use the Greek letter lambda for lambda functions in the REPL, but in code you enter in the editor you have to write out the word "lambda"? Why can you, in the REPL, accidentally delete the > prompt? Why is there endless documentation referring to Gambit on desktop, but not about the app itself? It's just more confusing and awkward than it needs to be. (The custom keys at the top of the keyboard are brilliant, though, once you get the hang of them: I wish they were available across iOS, I'd never have to flip through different pages of the keyboard again.) ### 2/5 — Me *2014-11-15* Would be way better if there were ways to (1) get sensor data and (2) networking connections out ## Frequently asked questions about Gambit REPL ### What is Gambit REPL?
