Ha! Very interesting. I can reproduce this behaviour. It is obviously wrong. This should take down the completion time to a still completely unacceptable 5 seconds on your system. > > > How long does '__fish_describe_command em' take? > > That takes about 5 seconds. The only way to work around this in a good way is to abort the description lookup if it takes too much time. Probably something like 0.5 seconds. That is a bit complex to implement, so it'll take some work. But I think it's the right thing to do in the long run. For now, you can work around this bug using the following commands: function __fish_describe_command end save_function __fish_describe_command > > > Right. 25 seconds to get completions makes them useless.
