The original meant to quote the whole thing inside a single quote, but AsciiDoc of course will strip that and instead makes the whole thing typeset in monospace. What you did is not wrong per-se, but I think quoting the whole thing, instead of quoting just what is inside the braces, i.e. '"HEAD^{/fix nasty bug}"' (or if you can manage it, using single quote instead of double quote) would read better. > A suffix '{caret}' to a revision parameter, followed by a brace > pair that contains a text led by a slash, > is the same as the ':/fix nasty bug' syntax below except that > it returns the youngest matching commit which is reachable from > the '' before '{caret}'. > > -':/', e.g. ':/fix nasty bug':: > +':/', e.g. ':/"fix nasty bug"':: Likewise. > @@ -185,7 +185,8 @@ existing tag object. > e.g. ':/^foo'.

Please sign-off your work (cf. Documentation/SubmittingPatches). Thanks. ``` ## Andreas Heiduk, 2017-08-16 21:15 Subject: Re: [PATCH] fix revisions doc about quoting for ':/' notation Message-ID: <956ccc83-c291-4217-795c-fcef33fac35b@gmail.com> URL: https://gitlist.dev/e/956ccc83-c291-4217-795c-fcef33fac35b%40gmail.com In-Reply-To: ``` Am 16.08.2017 um 05:21 schrieb ryenus: > To make sure the `` in `:/` is seen as one search string, > one should quote/escape `` properly. > > Especially, the example given in the manual `:/fix nasty bug` does not > work because of missing quotes.

This is agnostic of the shell or other UI with their different quoting rules. For example users of fish must quote `rev@{2}`. A GUI might require no quoting at all. In that case `:/"fix nasty bugs"` would be given to git verbatim and hence not find the revision. Also: Other examples like `HEAD@{5 minutes ago}` need the same quoting. So my suggestion is to not use quoting in the examples and provide only a hint in the text. Example: {caret}{/}', e.g. 'HEAD^{/fix nasty bug}':: A suffix '{caret}' to a revision parameter, followed by a brace pair that contains a text led by a slash, is the same as the ':/fix nasty bug' syntax below except that it returns the youngest matching commit which is reachable from the '' before '{caret}'. + Depending on the given text the shell's word splitting rules + might require additional quoting. ``` ## Junio C Hamano, 2017-08-16 21:57 Subject: Re: [PATCH] fix revisions doc about quoting for ':/' notation Message-ID: URL: https://gitlist.dev/e/xmqqo9rfi3b2.fsf%40gitster.mtv.corp.google.com In-Reply-To: <956ccc83-c291-4217-795c-fcef33fac35b@gmail.com> ``` Andreas Heiduk writes: > Am 16.08.2017 um 05:21 schrieb ryenus: >> To make sure the `` in `:/` is seen as one search string, >> one should quote/escape `` properly. >> >> Especially, the example given in the manual `:/fix nasty bug` does not >> work because of missing quotes.

That sounds like a very safe change to adopt, regardless of what we decide to do to the other part of the proposed change. Thanks. ``` ## ryenus, 2017-08-17 07:01 Subject: Re: [PATCH] fix revisions doc about quoting for ':/' notation Message-ID: URL: https://gitlist.dev/e/CAKkAvay1gJTLJrGLb3aFMJmnyQjPhSD9cx0DRAAN3Mh5NAhfiQ%40mail.gmail.com In-Reply-To: ``` On 17 August 2017 at 05:57, Junio C Hamano wrote: > Andreas Heiduk writes: > >> Am 16.08.2017 um 05:21 schrieb ryenus: >>> To make sure the `` in `:/` is seen as one search string, >>> one should quote/escape `` properly. >>> >>> Especially, the example given in the manual `:/fix nasty bug` does not >>> work because of missing quotes.

I've just sent a v2 patch, which leaves the original example as-is, meanwhile added a example inside the explanation. Thanks! ```
