Can fish shell interpolate functions when expanding to their full form?

问题

Given the following abbreviation, where git_branch_name returns the current git branch name:

abbr -a ggl 'git pull origin (git_branch_name)'

Is there a way to have the the function interpolate when the abbreviation is expanded?

# This is what the abbreviation expands to
$ git pull origin (git_branch_name)

# This is the expansion I am looking for
$ git pull origin master

回答1:

No, it is not yet possible for an abbreviation to run code when it expands. I expect we'll add this capability before long.

回答2:

You can use a function instead:

function ggl
    commandline 'git pull origin '(git_branch_name)
end

or even a keybinding (Alt + g)

bind \eg 'commandline -i "git pull origin"(git_branch_name)'
