alda play --code misinterprets snippets with custom instrument names #408
Comments
This works for me in my Bash shell:
Based on this, it looks like you can use single quotes in PowerShell too. Can you try the snippet above? I'm not sure why the version with the backticks wouldn't work as well, based on what I read in the article that I linked. 🤷♂️ |
I tried the snippet above. Same problem |
I'm stumped. No idea why that wouldn't work, unless quoting works completely unexpectedly in PowerShell. 🤨 |
Ok, where it gets even weirder is that Windows CMD (arguably a much "dumber" shell) has no problem with it, so long as you escape the quotes properly: |
That error message makes "sense" to me in that that's the error message I would expect if you ran this:
It seems like because of some Windows-specific shell quoting issues that I don't understand, it isn't actually escaping the first double quote after |
And I have heard that single quotes don't work in CMD, for what it's worth. |
It seems clear to me that this is an issue with the way that quoting works in CMD and PowerShell, and not a bug in Alda, so closing this issue. Happy to reopen it if there are other perspectives! |
🐞 Bug report 🐞
Description
I found that trying to play a code snippet with custom instruments behaves in an unexpected way.
An easy test case is the following code snippet:
piano "pi-1": c d e f g piano "pi-2":c < b a g f
Playing this on PowerShell using the command
alda play --code "piano `"pi-1`": c d e f g piano `"pi-2`": c < b a g f"
(I believe on Bash it would bealda play --code "piano \"pi-1\": c d e f g piano \"pi-2\": c < b a g f"
) prodces the error message<no file>:1:1 undefined variable: piano
. Saving the snippet to a file and playing withalda play --file
runs normally.It seems to cause problems even if the instruments are on separate lines, as in
