Git checkout has 2 major modes of operating: 1. Checking out branches (and then update your working tree to match that commit. 2. Checking out 1 or more files from a commit. The first four lines of the synopsis match mode nr. 1. The next two belong to mode nr. 2. The pathspec in the synopsis line you are quoting is required, because that's how you tell git you want mode nr 2. That's why it's not mentioned between []. The last section under description explains that mode. Do you feel this distinction needs to be made more clear? Kevin. ^ permalink raw reply [flat|nested] 11+ messages in thread

Day" <rpjday@crashcourse.ca> writes: > it's simply a matter of the forms not matching between the SYNOPSIS > and the DESCRIPTION sections. am i making sense? I think the whole thing is wrong and the root cause is because the (relatively newer) description of the "--patch" mode lazily tried to piggy-back the description of existing "check out from the index or tree-ish" mode, ending up in a confusing description. "git checkout [<tree-ish>] -- <pathspec>..." is a way to overwrite the working tree files with what is in the object store. When you give <tree-ish>, the paths that match the <pathspec> are grabbed from the tree-ish, added to the index, and overwrites the working tree files. In this mode, you need to have at least one pathspec element on the command line, so <pathspec> is mandatory. With no pathspec, if <tree-ish> happens to be a commit-ish, then the operation is "check out the commit, so that we can prepare to make a new commit as its child". "git checkout -p/--patch [<tree-ish>]" is quite different. It can be used without any <pathspec> to pick and choose from all changes treewide, but you can use <pathspec> to limit the changes you need to choose from. Something like the following may be a good starting point. As I didn't spend many brain-cycles to come up with a description for the "--patch" mode, that paragraph needs a total rewrite on top, but I think the structure to separate the normal "per-path" checkout mode and "patch" mode and describe it separately should make it a lot clearer to see what is being described. Short of such a fundamental correction, git checkout [-p|--patch] [<tree-ish>] -- [<pathspec>...] would allow you to give none of -p/--patch/<pathspec>, which is totally a different operation from what is being described in the text.

J. Day There are "git checkout [-p][<tree-ish>][--][<paths>...]" in the SYNOPSIS section, and "git checkout [-p][<tree-ish>][--]<paths>..." as the header for the section that explains the "check out paths from index/tree-ish" mode. It is unclear if we require at least one path, or it is entirely optional. Actually, both are wrong. Without the "-p(atch)" option, you must have <pathspec> (otherwise, with a commit that is a <tree-ish>, you would be checking out that commit to build a new history on top of it). With it, it is already clear that you are checking out paths, it is optional. In other words, you cannot omit both. The source of the confusion is that -p(atch) is described as if it is just another "optional" part and its description is lumped together with the non patch mode, even though the actual end user experience is vastly different. Let's split the entry into two, and describe the regular mode and the patch mode separately. This allows us to make it clear that the regular mode MUST be given at least one pathspec, that the patch mode can be invoked with either '-p' or '--patch' but one of these must be given, and that the pathspec is entirely optional in the patch mode. Also, revamp the explanation of "checkout paths" by removing extraneous description at the beginning, that says "checking out paths is not checking out a branch". Explaining what it is for and when the user wants to use it upfront is the most direct way to help the readers.

Git commands consistently accept a tag pointing to a commit where a commit is expected, so emphasizing that feature by calling it a commit-ish only adds distraction. That's not what this patch is about, though. Even for this particular form, the current file is inconsistent about whether to call the arguments '<paths>...' or '<pathspec>...'. "<paths>..." is even more strange when I think about it for a moment, since it is the plural of the plural of path --- i.e., it implies that each argument names multiple paths.

I was tempted to read this as "The original contents of", but that was a misreading. - Similarly, "the contents from" perhaps should be "the content of". Stepping back, what problem is this solving in the original text? It said When <paths> or --patch are given, git checkout does *not* switch branches. It updates the named paths in the working tree from the index file or from a named <tree-ish> (most often a commit). In this case, the -b and --track options are meaningless and giving either of them results in an error. The <tree-ish> argument can be used to specify a specific tree-ish (i.e. commit, tag or tree) to update the index for the given paths before updating the working tree. The "or --patch" would have to go, of course. Is the problem that the description focuses too much on what this form does not do? To fix that, it could say Replace matching paths in the working tree with content from the index or the named tree (most often a commit). The <tree-ish> argument can be used to specify a specific tree, commit, or tag that will be used to update the entries for matching paths in the index before updating the working tree. One thing that doesn't tell is what happens to files that are present in the worktree but deleted in the index or the named tree. Does "git checkout" delete them?

The "restore" was taken from the sentence that was buried in the paragraph removed by this patch. I think the original used the word, fully intending to evoke "an art conservation project" connotation---after all, the user made a mess in the working tree and a known-to-be-good copy stored in the index or tree is used to restore the working tree copy. > To fix that, it could say > > Replace matching paths in the working tree with content > from the index or the named tree (most often a commit).

It could (and it was what my earlier draft said), but I found it less clear than necessary. It does not matter the data goes from tree-ish to index and then to the working tree, and a more important thing is to say both are updated from the tree-ish, for example. > ... aha, now I see the next paragraph where this text came from.

That might sound technically more accurate, but when we consider that this application is done in reverse, it is probably not such a good idea to say "apply" here. The user chooses which one to use, and the way it is "used" is by applying the hunk in reverse. "choose the preimage of which hunks to use in the result" may be more technically accurate, but it is a mouthful. I dunno. The interactive UI explains it by saying Discard this hunk from worktree? which is probably the easiest explanation. > The options section explains --patch again.
