Don't use abbreviated long options "function --argument" is not a thing, it's "--argument-names". This only accidentally works because our getopt is awful and allows abbreviated long options. Similarly, one argparse test used "--d" instead of "-d" or "--def". 2020-09-19 17:39:51 +08:00			`function __history_completions --argument-names limit`

Add history-based completions for autojump's j command j does not have any "logical" source of completions, but it almost often called with arguments that have been seen before (since it is used to jump to favorite/recent directories). We can search the history for possible completions and use those. This is an example of the behavior mentioned in #4344 as a possible enhancement for fish 3.0, where completions can be provided from history if none are otherwise found. 2017-09-21 09:50:10 +08:00			`end`

Erase default autojump completions in j.fish completions The default completions that autojump ships with for fish are broken (emitting output like "1\___\#...") as they use hackes to work around the previous lack of `complete -k`. The history-based autojump completions fully replace it. 2018-04-15 12:23:33 +08:00			`# erase the stock autojump completions, which are no longer needed with this`
