April issues on Windows 10 with LispWorks 8.1 Pro 32-bit and SBCL 2.5.9
Hello, I'm giving April a try on Windows 10 where I usually use Emacs + SLIME and LispWorks 8.1 Pro 32-bit.
When I first ran (ql:quickload "april") in LispWorks I got an error about System "cape" not found so I cloned the repo as a local project. I have the most recent "quicklisp" version (2025-06-22).
Unfortunately the SLIME output Gray stream has an underlying type of BASE-CHAR which is 8-bit, so whenever it tries to print the final Specified idiom ｢APRIL｣ with 96 lexical functions, 17 lexical operators, 2 aliased functions, 18 utility functions and 1140 unit tests. message from within SLIME I get an error #\｢ (of type CHARACTER) is not of type BASE-CHAR.. If I run this from a PowerShell window it's fine.
When I run (april::load-libs) and (april::run-lib-tests) (still using LW8.1, from a PowerShell window) it reports one failure, on line 41:
× #(#(#\┌ #\→ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ #\─ ... is expected to be #("┌→──────────────────┐" "│ ┌→──┐ ┌→────┐ │" "│ 1 a │abc│ ↓1 2 3│ │" "│ - └───┘ │4 5 6│ │" "│ └~────┘ │" "└∊──────────────────┘")
Here is the entire output: april-run-lib-tests.txt
SBCL 2.5.9 works fine in Emacs, and when I run(april::run-lib-tests) it reports "Ran 607 tests, 0 failed."
Thanks for April and all the great documentation and links, I'm looking forward to giving APL a try and hopefully integrating it into my new machine learning project. I'm enjoying listening to your podcast interview as well.
Here's the display of the LispWorks SLIME error:

Thanks for doing these tests on the LW+Windows setup. It looks like the ｢ character isn't working correctly for that setup, I can check out some other characters it could be changed to. Kind of surprised the test output with all the APL chars doesn't cause a problem.
If you'd like me to run any more tests, sample code etc. just let me know.
Sure, could you try running the demo in april/demos/ncurses? There's a readme in that folder explaining how to do so. It's a Conway visualization meant to be displayed in a terminal, I'm curious to see how it'll work in Windows.
OK, the short answer is: running the demo immediately and silently terminates the process.
The long answer: I downloaded and compiled a 32-bit version of PDCurses and ran the demo "manually":

Thanks, very strange. In your first PDCurses attempt were you able to see and use the ncurses program? There are clearly a lot of hurdles to make this work under Windows.
No, I haven't seen any ncurses output other than the clearing of the window. No indication that keypresses were being processed either.
I played around with the "hello world" code in https://github.com/armlesshobo/croatoan/blob/master/doc/slime.md with both PDCurses and the MSYS2 libncursesw6.dll in both a PowerShell window and an MSYS2 shell window and couldn't get any text on the screen, so there are definitely deeper issues there.
