Define the implementation of the built-in command `foo` with + * signature: + * + * int cmd_foo(int argc, const char **argv, const char *prefix); + * + * . Add the external declaration for the function to `builtin.h`. + * + * .

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. + * + * `SUPPORT_SUPER_PREFIX`: + * + * The built-in supports `--super-prefix`. + * + * `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. + * + * . 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. + * + * .
