/* 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 in optiondefs.h (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 macro definition to the optiondefs.h file.
* - Add a variable to the window or buffer struct in structs.h.
* - For a window option, add some code to copy_winopt().
* - For a window string option, add code to check_win_options() and
* clear_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
* set_num_option().
* - If it's a list of flags, add some code in did_set_string_option(), 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.
