2009-11-13Teach git var about GIT_PAGERJonathan Nieder
Expose the command found by setup_pager() for scripts to use. Scripts can use this to avoid repeating the logic to look for a proper pager in each command. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-11-13Teach git var about GIT_EDITORJonathan Nieder
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.

2009-11-13Suppress warnings from "git var -l"Jonathan Nieder
For scripts using "git var -l" to read all logical variables at once, not all per-variable warnings will be relevant. So suppress them. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-01Style fixes, add a space after if/for/while.Brian Gianforcaro
The majority of code in core git appears to use a single space after if/for/while. This is an attempt to bring more code to this standard. These are entirely cosmetic changes. Signed-off-by: Brian Gianforcaro <b.gianfo@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-26Add calls to git_extract_argv0_path() in programs that call git_config_*Steffen Prohaska
Programs that use git_config need to find the global configuration. When runtime prefix computation is enabled, this requires that git_extract_argv0_path() is called early in the program's main(). This commit adds the necessary calls. Signed-off-by: Steffen Prohaska <prohaska@zib.de> Acked-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-05-14Provide git_config with a callback-data parameterJohannes Schindelin
git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

2008-03-15var: Don't require to be in a git repository.Frank Lichtenheld
git var works fine even when not called in a git repository. So don't require it. This will make it possible to remove this pre-condition for some other git commands as well. Signed-off-by: Frank Lichtenheld <frank@lichtenheld.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-12-09Re-fix "builtin-commit: fix --signoff"Junio C Hamano
An earlier fix to the said commit was incomplete; it mixed up the meaning of the flag parameter passed to the internal fmt_ident() function, so this corrects it. git_author_info() and git_committer_info() can be told to issue a warning when no usable user information is found, and optionally can be told to error out. Operations that actually use the information to record a new commit or a tag will still error out, but the caller to leave reflog record will just silently use bogus user information. Not warning on misconfigured user information while writing a reflog entry is somewhat debatable, but it is probably nicer to the users to silently let it pass, because the only information you are losing is who checked out the branch. * git_author_info() and git_committer_info() used to take 1 (positive int) to error out with a warning on misconfiguration; this is now signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME. * These functions used to take -1 (negative int) to warn but continue; this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME. * fmt_ident() function implements the above error reporting behaviour common to git_author_info() and git_committer_info(). A symbolic constant IDENT_NO_DATE can be or'ed in to the flag parameter to make it return only the "Name <email@address.xz>". * fmt_name() is a thin wrapper around fmt_ident() that always passes IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

2007-06-07War on whitespaceJunio C Hamano
This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

2007-01-28Don't force everybody to call setup_ident().Junio C Hamano
Back when only handful commands that created commit and tag were the only users of committer identity information, it made sense to explicitly call setup_ident() to pre-fill the default value from the gecos information. But it is much simpler for programs to make the call automatic when get_ident() is called these days, since many more programs want to use the information when updating the reflog.

2006-12-20simplify inclusion of system header files.Junio C Hamano
This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-19Delay "empty ident" errors until they really matter.Junio C Hamano
Previous one warned people upfront to encourage fixing their environment early, but some people just use repositories and git tools read-only without making any changes, and in such a case there is not much point insisting on them having a usable ident. This round attempts to move the error until either "git-var" asks for the ident explicitly or "commit-tree" wants to use it. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-11-25git-var: make it work in subdirectory.Junio C Hamano
Use setup_git_directory() so that it can find its .git directory. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-11-22git-var: constness and globalness cleanup.Junio C Hamano
var.c::git_var read function did not have to return writable strings; make it and the functions it points at return const char * instead. ident.c::get_ident() did not need to be global, so make it static. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-12Use git config file for committer name and email infoLinus Torvalds
This starts using the "user.name" and "user.email" config variables if they exist as the default name and email when committing. This means that you don't have to use the GIT_COMMITTER_EMAIL environment variable to override your email - you can just edit the config file instead. The patch looks bigger than it is because it makes the default name and email information non-static and renames it appropriately. And it moves the common git environment variables into a new library file, so that you can link against libgit.a and get the git environment without having to link in zlib and libcrypt. In short, most of it is renaming and moving, the real change core is just a few new lines in "git_default_config()" that copies the user config values to the new base. It also changes "git-var -l" to list the config variables. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-07-30[PATCH] Unify usage strings declarationPetr Baudis

2005-07-15[PATCH] Add git-var a tool for reading interesting git variables.Eric W. Biederman
Sharing code between shell scripts and C is a challenge. The program git-var allows us to have a set of named values that a shell script can interrogate and a normal C program can simply call the functions that compute them. Allowing sharing when computing plain test values. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
