So I have 2 files, file1.sml & file2.sml both of which have correct code & I'm using a Windows operating system.
When I run Emacs and execute: use "file1.sml", it runs fine but then when I simply go to tab File->Close to close the file and then I drag file2.sml into Emacs and try to run it the same way, it gives the following error:
[use failed: Io: openIn failed on "file2.sml", Win32TextPrimIO:openRd: failed]
I tried restarting SML by doing c-c c-d but it's the same. So what I do is I quit Emacs and then start again and run file2.sml and it runs fine.
Why do I have to quit just to run another file?
there are few things you can right now do. 1. save the file you created before trying to open it. i mean yes it sounds lame, but people new to programming ( as you tried to save it as "file.sml" , First save it. 2. try to change \ to // Win32TextPrimIO:openRd: failed
because it cant find it.
