In that case, you're still clueless about how it works and why it's in bash. It's in bash because a bash *function* (as opposed to script) is the only way that a bash command can change the environment of the shell that calls it. Hint: It's not a bash script, because that would run in a subshell, where the only environment it can change it the subshell's environment. If a similar feature exists in Fish then it'd be a snip to translate. If not, then a solution using symlinks might be the only way. I've written such bash functions (upwards of 100 lines) for managing the history of the "cd" command in the past. It's not rocket science.
