In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

<repository>::
|
|
The "remote" repository that is the source of a fetch
|
|
or pull operation. This parameter can be either a URL
|
|
(see the section <<URLS,GIT URLS>> below) or the name
|
|
of a remote (see the section <<REMOTES,REMOTES>> below).
|
|
|
|
ifndef::git-pull[]
|
|
<group>::
|
|
A name referring to a list of repositories as the value
|
|
of remotes.<group> in the configuration file.
|
|
(See linkgit:git-config[1]).
|
|
endif::git-pull[]
|
|
|
|
<refspec>::
|
|
The format of a <refspec> parameter is an optional plus
|
|
`+`, followed by the source ref <src>, followed
|
|
by a colon `:`, followed by the destination ref <dst>.
|
|
+
|
|
The remote ref that matches <src>
|
|
is fetched, and if <dst> is not empty string, the local
|
|
ref that matches it is fast-forwarded using <src>.
|
|
If the optional plus `+` is used, the local ref
|
|
is updated even if it does not result in a fast-forward
|
|
update.
|
|
+
|
|
[NOTE]
|
|
If the remote branch from which you want to pull is
|
|
modified in non-linear ways such as being rewound and
|
|
rebased frequently, then a pull will attempt a merge with
|
|
an older version of itself, likely conflict, and fail.
|
|
It is under these conditions that you would want to use
|
|
the `+` sign to indicate non-fast-forward updates will
|
|
be needed. There is currently no easy way to determine
|
|
or declare that a branch will be made available in a
|
|
repository with this behavior; the pulling user simply
|
|
must know this is the expected usage pattern for a branch.
|
|
+
|
|
[NOTE]
|
|
You never do your own development on branches that appear
|
|
on the right hand side of a <refspec> colon on `Pull:` lines;
|
|
they are to be updated by 'git fetch'. If you intend to do
|
|
development derived from a remote branch `B`, have a `Pull:`
|
|
line to track it (i.e. `Pull: B:remote-B`), and have a separate
|
|
branch `my-B` to do your development on top of it. The latter
|
|
is created by `git branch my-B remote-B` (or its equivalent `git
|
|
checkout -b my-B remote-B`). Run `git fetch` to keep track of
|
|
the progress of the remote side, and when you see something new
|
|
on the remote branch, merge it into your development branch with
|
|
`git pull . remote-B`, while you are on `my-B` branch.
|
|
+
|
|
[NOTE]
|
|
There is a difference between listing multiple <refspec>
|
|
directly on 'git pull' command line and having multiple
|
|
`Pull:` <refspec> lines for a <repository> and running
|
|
'git pull' command without any explicit <refspec> parameters.
|
|
<refspec> listed explicitly on the command line are always
|
|
merged into the current branch after fetching. In other words,
|
|
if you list more than one remote refs, you would be making
|
|
an Octopus. While 'git pull' run without any explicit <refspec>
|
|
parameter takes default <refspec>s from `Pull:` lines, it
|
|
merges only the first <refspec> found into the current branch,
|
|
after fetching all the remote refs. This is because making an
|
|
Octopus from remote refs is rarely done, while keeping track
|
|
of multiple remote heads in one-go by fetching more than one
|
|
is often useful.
|
|
+
|
|
Some short-cut notations are also supported.
|
|
+
|
|
* `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`;
|
|
it requests fetching everything up to the given tag.
|
|
* A parameter <ref> without a colon is equivalent to
|
|
<ref>: when pulling/fetching, so it merges <ref> into the current
|
|
branch without storing the remote branch anywhere locally
