zsh alias -> function?
Suppose I have:
alias gg="git grep"
then stuff like:
gg "int x"
works, but
gg int x
gets complaints. Is there a way to rewrite gg as a function in zsh so that it takes all the arguments after gg, and开发者_开发技巧 stuffs them into a string?
Thanks!
gg() { git grep "$*"; }
For your particular use case, this is a bad idea. git-grep
is expecting a single-arg pattern. You're trying to get the shell to treat your space (between int and x) as part of the pattern. This will break quickly when you try something like: gg foo.*bar
or various other things that the shell might interpret. So anything after gg
really should be quoted. This is why git grep int x
also doesn't work: fatal: ambiguous argument 'x': unknown revision or path not in the working tree...
If you think gg
is a worthwhile keystroke saver, you should keep your arg to it consistent with what git-grep
expects. Your original alias is fine for this. And continue to single- or double-quote your pattern, just like you do with any other regex-accepting command.
