/* vi:set ts=8 sts=4 sw=4 noet: * * VIM - Vi IMproved by Bram Moolenaar * * Do ":help uganda" in Vim to read copying and usage conditions. * Do ":help credits" in Vim to see a list of people who contributed. * See README.txt for an overview of the Vim source code. */ /* * Code to handle user-settable options. This is all pretty much table- * driven. Checklist for adding a new option: * - Put it in the options array below (copy an existing entry). * - For a global option: Add a variable for it in option.h. * - For a buffer or window local option: * - Add a PV_XX entry to the enum below. * - Add a variable to the window or buffer struct in structs.h. * - For a window option, add some code to copy_winopt(). * - For a buffer option, add some code to buf_copy_options(). * - For a buffer string option, add code to check_buf_options(). * - If it's a numeric option, add any necessary bounds checks to do_set(). * - If it's a list of flags, add some code in do_set(), search for WW_ALL. * - When adding an option with expansion (P_EXPAND), but with a different * default for Vi and Vim (no P_VI_DEF), add some code at VIMEXP. * - Add documentation! One line in doc/quickref.txt, full description in * options.txt, and any other related places. * - Add an entry in runtime/optwin.vim. * When making changes: * - Adjust the help for the option in doc/option.txt. * - When an entry has the P_VIM flag, or is lacking the P_VI_DEF flag, add a * comment at the help for the 'compatible' option. */ #define IN_OPTION_C #include "vim.h" #include "optiondefs.h" static void set_options_default(int opt_flags);
