cl-repl Customer Insights

1. All works well now, Great work! Five stars for opening a door for me to new options and possibilities for programming on the small portable computer I now hold in my hands.The power of lisp in your pocket ! The ability to load programs and then optionally run them using the Lambda button makes this especially versatile.

2. Needs a way to hide interpreter - it is useless spacetaker while writing program (and space is valuable).Awesome, I love being able to run and write code anywhere, and the full power of Common Lisp at that.

3. Saving your code the first time is a bit unintuitive to my windows brain.As a beginner for learning common lisp, this has been such a great asset.

4. I would pay a dollar for dark theme!It is noteworthy that, having lisp been a resource-intensive system only available at advanced computer labs at MIT now fits in my handheld device using up but scant storage memory and cycles.

5. Thanks! Dunno why I didn't think of that since something like this occurs in another Lisp that I use on occasion and it's the same fix....Great to have a simple and easy to use download-and-go Common lisp REPL + editor available from the play store.

6. Having now used this app for quite some time I can easily say that is easily the preferred medium for pocket computingI copied and pasted a Mandelbrot Zoomer code I made on my desktop and it worked beautifully! The only thing I can suggest is making the actual act of text editing a little bit easier (having a select all button would be nice).

7. I have been passing time writing common lisp code wherever I want.

8. Common Lisp is a key to that as it's so succinct and effective.Needs description so that people can find it not only via subreddit.

9. If you can see beyond the well known use of parenthesis to the elegance and sheer power of lisp, you'll understand why many prefer lisp over traditional functional languages.

10. I was initially unable to save files to external memory, but the developer worked with me to identify the issue, and had a bug fix sent out in a matter of days.

11. (I have figured out the reverse: I can get files from the sd card to the app.)Really happy to have a CL repl on my phone.
