* var: add GIT_SEQUENCE_EDITOR variableSean Allred2022-12-181-0/+8
| | | | | | | | | | | | | | The editor program used by Git when editing the sequencer "todo" file is determined by examining a few environment variables and also affected by configuration variables. Introduce "git var GIT_SEQUENCE_EDITOR" to give users access to the final result of the logic without having to know the exact details. This is very similar in spirit to 44fcb497 (Teach git var about GIT_EDITOR, 2009-11-11) that introduced "git var GIT_EDITOR".

* var: do not print usage() with a correct invocationSean Allred2022-11-271-1/+2
| | | | | | | | | | | | | | | | | | Before, git-var could print usage() even if the command was invoked correctly with a variable defined in git_vars -- provided that its read() function returned NULL. Now, we only print usage() only if it was called with a logical variable that wasn't defined -- regardless of read(). Since we now know the variable is valid when we call read_var(), we can avoid printing usage() here (and exiting with code 129) and instead exit quietly with code 1. While exiting with a different code can be a breaking change, it's far better than changing the exit status more generally from 'failure' to 'success'.

* doc txt & -h consistency: correct padding around "[]()"Ævar Arnfjörð Bjarmason2022-10-131-1/+1
| | | | | | | | | | The whitespace padding of alternatives should be of the form "[-f | --force]" not "[-f|--force]". Likewise we should not have padding before the first option, so "(--all | <pack-filename>...)" is correct, not "( --all | <pack-filename>... )".

* var: add GIT_DEFAULT_BRANCH variableThomas Weißschuh2021-11-031-0/+3
| | | | | | | | | | | | | | | | | | | | Introduce the logical variable GIT_DEFAULT_BRANCH which represents the the default branch name that will be used by "git init". Currently this variable is equivalent to git config init.defaultbranch || 'master' This however will break if at one point the default branch is changed as indicated by `default_branch_name_advice` in `refs.c`. By providing this command ahead of time users of git can make their code forward-compatible.

* doc: keep first level section header in upper caseNguyễn Thái Ngọc Duy2018-05-021-2/+2
| | | | | | | | | | | | | | | | | | | When formatted as a man page, 1st section header is always in upper case even if we write it otherwise. Make all 1st section headers uppercase to keep it close to the final output. This does affect html since case is kept there, but I still think it's a good idea to maintain a consistent style for 1st section headers. Some sections perhaps should become second sections instead, where case is kept, and for better organization. I will update if anyone has suggestions about this. While at there I also make some header more consistent (e.g. examples vs example) and fix a couple minor things here and there.

* ident: report passwd errors with a more friendly messageJeff King2012-05-221-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When getpwuid fails, we give a cute but cryptic message. While it makes sense if you know that getpwuid or identity functions are being called, this code is triggered behind the scenes by quite a few git commands these days (e.g., receive-pack on a remote server might use it for a reflog; the current message is hard to distinguish from an authentication error). Let's switch to something that gives a little more context. While we're at it, we can factor out all of the cut-and-pastes of the "you don't exist" message into a wrapper function. Rather than provide xgetpwuid, let's make it even more specific to just getting the passwd entry for the current uid. That's the only way we use getpwuid anyway, and it lets us make an even more specific error message. The current message also fails to mention errno. While the usual cause for getpwuid failing is that the user does not exist, mentioning errno makes it easier to diagnose these problems. Note that POSIX specifies that errno remain untouched if the passwd entry does not exist (but will be set on actual errors), whereas some systems will return ENOENT or similar for a missing entry. We handle both cases in our wrapper. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* drop length limitations on gecos-derived names and emailsJeff King2012-05-221-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we pull the user's name from the GECOS field of the passwd file (or generate an email address based on their username and hostname), we put the result into a static buffer. While it's extremely unlikely that anybody ever hit these limits (after all, in such a case their parents must have hated them), we still had to deal with the error cases in our code. Converting these static buffers to strbufs lets us simplify the code and drop some error messages from the documentation that have confused some users. The conversion is mostly mechanical: replace string copies with strbuf equivalents, and access the strbuf.buf directly. There are a few exceptions: - copy_gecos and copy_email are the big winners in code reduction (since they no longer have to manage the string length manually) - git_ident_config wants to replace old versions of the default name (e.g., if we read the config multiple times), so it must reset+add to the strbuf instead of just adding Note that there is still one length limitation: the gethostname interface requires us to provide a static buffer, so we arbitrarily choose 1024 bytes for the hostname.

* var doc: advertise current DEFAULT_PAGER and DEFAULT_EDITOR settingsJonathan Nieder2012-04-101-0/+6
| | | | | | | | | | | | | | | | | | Document the default pager and editor chosen at compile time in the git-var(1) manpage so users curious about what command _this_ copy of git will fall back to when EDITOR, VISUAL, and PAGER are unset can find the answer quickly. In builds leaving those settings uncustomized, this patch makes the manpage continue to say "usually vi" and "usually less" so the formatted documentation is usable for a wide audience including users of custom builds that change those settings. If you would like your copy of the docs to be less noncommittal, you will need to set DEFAULT_PAGER=less and DEFAULT_EDITOR=vi explicitly.

* var doc: default editor and pager are configurable at build timeJonathan Nieder2012-03-311-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | Some distributors customize the fallback pager and editor used by git commands when the user has not indicated a preference via the core.editor/core.pager configuration or GIT_EDITOR, GIT_PAGER, VISUAL, EDITOR, and PAGER environment variables, and git's build system provides DEFAULT_PAGER and DEFAULT_EDITOR makefile settings to help them with that (see v1.6.6-rc0~24, 2009-11-20). Unfortunately those compile-time settings do not affect the documentation, so the uninitiated user who tries to understand git by reading the git-var(1) manpage can easily be confused when git falls back to 'nano' and 'more' instead of 'vi' and 'less'. Even if the distributor patches the distributed docs to reflect the new default, the user may read the official documentation from the git-htmldocs repository online and be confused in the same way. Add a few words stating that the defaults are customizable at compile time to make the behavior crystal clear.

* Documentation: use [verse] for SYNOPSIS sectionsMartin von Zweigbergk2011-07-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | The SYNOPSIS sections of most commands that span several lines already use [verse] to retain line breaks. Most commands that don't span several lines seem not to use [verse]. In the HTML output, [verse] does not only preserve line breaks, but also makes the section indented, which causes a slight inconsistency between commands that use [verse] and those that don't. Use [verse] in all SYNOPSIS sections for consistency. Also remove the blank lines from git-fetch.txt and git-rebase.txt to align with the other man pages. In the case of git-rebase.txt, which already uses [verse], the blank line makes the [verse] not apply to the last line, so removing the blank line also makes the formatting within the document more consistent. While at it, add single quotes to 'git cvsimport' for consistency with other commands.

* doc: drop author/documentation sections from most pagesJeff King2011-03-111-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The point of these sections is generally to: 1. Give credit where it is due. 2. Give the reader an idea of where to ask questions or file bug reports. But they don't do a good job of either case. For (1), they are out of date and incomplete. A much more accurate answer can be gotten through shortlog or blame. For (2), the correct contact point is generally git@vger, and even if you wanted to cc the contact point, the out-of-date and incomplete fields mean you're likely sending to somebody useless. So let's drop the fields entirely from all manpages except git(1) itself. We already point people to the mailing list for bug reports there, and we can update the Authors section to give credit to the major contributors and point to shortlog and blame for more information. Each page has a "This is part of git" footer, so people can follow that to the main git manpage.

| | | | | | | | | | | | | | | | | | | | | | | | Expose the command used by launch_editor() for scripts to use. This should allow one to avoid searching for a proper editor separately in each command. git_editor(void) uses the logic to decide which editor to use that used to live in launch_editor(). The function returns NULL if there is no suitable editor; the caller is expected to issue an error message when appropriate. launch_editor() uses git_editor() and gives the error message the same way as before when EDITOR is not set. "git var GIT_EDITOR" gives the editor name, or an error message when there is no appropriate one. "git var -l" gives GIT_EDITOR=name only if there is an appropriate editor.

* Documentation: be consistent about "git-" versus "git "Jonathan Nieder2008-07-011-2/+2
| | | | | | | | | | | | | | | | | | | | Since the git-* commands are not installed in $(bindir), using "git-command <parameters>" in examples in the documentation is not a good idea. On the other hand, it is nice to be able to refer to each command using one hyphenated word. (There is no escaping it, anyway: man page names cannot have spaces in them.) This patch retains the dash in naming an operation, command, program, process, or action. Complete command lines that can be entered at a shell (i.e., without options omitted) are made to use the dashless form. The changes consist only of replacing some spaces with hyphens and vice versa.

(2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean.
