I don't think I've ever tried writing an empty block for git before. It's braces containing a semicolon and comment?

Ah, yes, I do intend to add code there subsequently, and this is just a placeholder so that it returns a correctly-constructed struct which doesn't support any operations until those operations are added. -Daniel *This .sig left intentionally blank* ``` ## Junio C Hamano, 2009-03-25 18:58 Subject: Re: [PATCH 3/5] Add option for using a foreign VCS Message-ID: <7vprg51lay.fsf@gitster.siamese.dyndns.org> URL: https://gitlist.dev/e/7vprg51lay.fsf%40gitster.siamese.dyndns.org In-Reply-To: ``` Daniel Barkalow writes: > On Wed, 25 Mar 2009, Junio C Hamano wrote: > >> Daniel Barkalow writes: >> >> >> > - if (!prefixcmp(url, "rsync:")) { >> >> > + if (remote && remote->foreign_vcs) { >> >> > + } else if (!prefixcmp(url, "rsync:")) { >> >> >> >> if (...) { >> >> ; /* empty */ >> >> } else ... >> > >> > I don't think I've ever tried writing an empty block for git before.

Ah, OK, thanks. In that case, I would say: if (...) { ; /* empty for now */ } else ... { or even more explicit: if (...) { /* * NEEDSWORK: later when we activate nitfol, * add code to let gostak distim the doshes here. */ ; } else ... { to allow people to grep for NEEDSWORK would be more appropriate. ```
