/*
* builtin API
* ===========
*
* Adding a new built-in
* ---------------------
*
* There are 4 things to do to add a built-in command implementation to
* Git:
*
* . Define the implementation of the built-in command `foo` with
* signature:
*
* int cmd_foo(int argc, const char **argv,
* const char *prefix, struct repository *repo);
*
* . Add the external declaration for the function to `builtin.h`.
*
* . Add the command to the `commands[]` table defined in `git.c`.
* The entry should look like:
*
* { "foo", cmd_foo, <options> },
*
* where options is the bitwise-or of:
*
* `RUN_SETUP`:
*
* If there is not a Git directory to work on, abort. If there
* is a work tree, chdir to the top of it if the command was
* invoked in a subdirectory. If there is no work tree, no
* chdir() is done.
*
* `RUN_SETUP_GENTLY`:
*
* If there is a Git directory, chdir as per RUN_SETUP, otherwise,
* don't chdir anywhere.
*
* `USE_PAGER`:
*
* If the standard output is connected to a tty, spawn a pager and
* feed our output to it.
*
* `NEED_WORK_TREE`:
*
* Make sure there is a work tree, i.e. the command cannot act
* on bare repositories.
* This only makes sense when `RUN_SETUP` is also set.
*
* `DELAY_PAGER_CONFIG`:
*
* If RUN_SETUP or RUN_SETUP_GENTLY is set, git.c normally handles
* the `pager.<cmd>`-configuration. If this flag is used, git.c
* will skip that step, instead allowing the built-in to make a
* more informed decision, e.g., by ignoring `pager.<cmd>` for
* certain subcommands.
*
* `NO_PARSEOPT`:
*
* Most Git builtins use the parseopt library for parsing options.
* This flag indicates that a custom parser is used and thus the
* builtin would not appear in 'git --list-cmds=parseopt'.
*
* . Add `builtin/foo.o` to `BUILTIN_OBJS` in `Makefile`.
*
* Additionally, if `foo` is a new command, there are 4 more things to do:
*
* . Add tests to `t/` directory.
*
* . Write documentation in `Documentation/git-foo.adoc`.
*
* . Add an entry for `git-foo` to `command-list.txt`.
*
* . Add an entry for `/git-foo` to `.gitignore`.
*
* As you work on implementing your builtin, be mindful that the
* following tests will check different aspects of the builtin's
* readiness and adherence to matching the documentation:
*
* * t0012-help.sh checks that the builtin can handle -h, which comes
* automatically with the parseopt API.
*
* * t0450-txt-doc-vs-help.sh checks that the -h help output matches the
* SYNOPSIS in the documentation for the builtin.
*
* * t1517-outside-repo.sh checks that the builtin can handle -h when
* run outside of the context of a repository. Note that this test
* requires that the usage has a space after the builtin name, so some
* minimum description of options is required.
*
*
* How a built-in is called
* ------------------------
*
* The implementation `cmd_foo()` takes three parameters, `argc`, `argv,
* and `prefix`. The first two are similar to what `main()` of a
* standalone command would be called with.
*
* When `RUN_SETUP` is specified in the `commands[]` table, and when you
* were started from a subdirectory of the work tree, `cmd_foo()` is called
* after chdir(2) to the top of the work tree, and `prefix` gets the path
* to the subdirectory the command started from. This allows you to
* convert a user-supplied pathname (typically relative to that directory)
* to a pathname relative to the top of the work tree.
*
* The return value from `cmd_foo()` becomes the exit status of the
* command.

/**
* If a built-in has DELAY_PAGER_CONFIG set, the built-in should call this early
* when it wishes to respect the `pager.foo`-config. The `cmd` is the name of
* the built-in, e.g., "foo". If a paging-choice has already been setup, this
* does nothing. The default in `def` should be 0 for "pager off", 1 for "pager
* on" or -1 for "punt".
*
* You should most likely use a default of 0 or 1. "Punt" (-1) could be useful
* to be able to fall back to some historical compatibility name.
