11 * Code to handle user-settable options. This is all pretty much table-
12 * driven. Checklist for adding a new option:
13 * - Put it in the options array below (copy an existing entry).
14 * - For a global option: Add a variable for it in option.h.
15 * - For a buffer or window local option:
16 * - Add a PV_XX entry to the enum below.
17 * - Add a variable to the window or buffer struct in structs.h.
18 * - For a window option, add some code to copy_winopt().
19 * - For a buffer option, add some code to buf_copy_options().
20 * - For a buffer string option, add code to check_buf_options().
21 * - If it's a numeric option, add any necessary bounds checks to do_set().
22 * - If it's a list of flags, add some code in do_set(), search for WW_ALL.
23 * - When adding an option with expansion (P_EXPAND), but with a different
24 * default for Vi and Vim (no P_VI_DEF), add some code at VIMEXP.
25 * - Add documentation! One line in doc/help.txt, full description in
26 * options.txt, and any other related places.
27 * - Add an entry in runtime/optwin.vim.
28 * When making changes:
29 * - Adjust the help for the option in doc/option.txt.
30 * - When an entry has the P_VIM flag, or is lacking the P_VI_DEF flag, add a
31 * comment at the help for the 'compatible' option.
