New Features in the Fish Shell

Re:New Features in the Fish Shell by nikisweeting on Tuesday September 29, 2020 @07:09PM (#24634120)

In particular I think Fish struggles with backgrounding of functions (backgrounding of non-fish commands seems to work fine).

  # these behave the same in bash but differently in fish
  some_command &  # this works
  some_function & # this does not

The relevant issues are listed here if you're curious about why it's difficult to implement this in Fish: https://github.com/pirate/fish-functions#issues-with-fish

Thanks for the link. Makes sense that if Fish doesn't fork itself and isn't multi-threaded then that would be a difficult feature to implement. I had the same consideration right at the conception of my project: fork or multi-thread? I went with the latter. But my shell diverges quite a bit from the typical design a shell would take so there's a lot of reasons it's sub-optimal compared to the excellent work the Fish guys have done with their shell.
