/* 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. */ #define IN_OPTION_C #include "vim.h" #include "optiondefs.h" static void set_options_default(int opt_flags); static void set_string_default_esc(char *name, char_u *val, int escape); static char_u *find_dup_item(char_u *origval, char_u *newval, size_t newvallen, long_u flags); static char_u *option_expand(int opt_idx, char_u *val); static void didset_options(void); static void didset_options2(void); #if defined(FEAT_EVAL) || defined(PROTO) static long_u *insecure_flag(int opt_idx, int opt_flags); #else # define insecure_flag(opt_idx, opt_flags) (&options[opt_idx].flags) #endif static char *set_bool_option(int opt_idx, char_u *varp, int value, int opt_flags); static char *set_num_option(int opt_idx, char_u *varp, long value, char *errbuf, size_t errbuflen, int opt_flags); static int find_key_option(char_u *arg_arg, int has_lt); static void showoptions(int all, int opt_flags); static int optval_default(struct vimoption *, char_u *varp, int compatible); static void showoneopt(struct vimoption *, int opt_flags); static int put_setstring(FILE *fd, char *cmd, char *name, char_u **valuep, long_u flags); static int put_setnum(FILE *fd, char *cmd, char *name, long *valuep); static int put_setbool(FILE *fd, char *cmd, char *name, int value); static int istermoption(struct vimoption *p); static char_u *get_varp_scope(struct vimoption *p, int scope); static char_u *get_varp(struct vimoption *); static void check_win_options(win_T *win); static void option_value2string(struct vimoption *, int scope); static void check_winopt(winopt_T *wop); static int wc_use_keyname(char_u *varp, long *wcp); static void compatible_set(void); #if defined(FEAT_EVAL) || defined(PROTO) static char *(p_bin_dep_opts[]) = {"textwidth", "wrapmargin", "modeline", "expandtab", NULL}; static char *(p_paste_dep_opts[]) = {"autoindent", "expandtab", "ruler", "showmatch", "smarttab", "softtabstop", "textwidth", "wrapmargin", #ifdef FEAT_RIGHTLEFT "hkmap", "revins", #endif #ifdef FEAT_VARTABS "varsofttabstop", #endif NULL}; static void didset_options_sctx(int opt_flags, char **buf); #endif /* * Initialize the 'shell' option to a default value. */ static void set_init_default_shell(void) { char_u *p; // Find default value for 'shell' option. // Don't use it if it is empty. if (((p = mch_getenv((char_u *)"SHELL")) != NULL && *p != NUL) #if defined(MSWIN) || ((p = mch_getenv((char_u *)"COMSPEC")) != NULL && *p != NUL) || ((p = (char_u *)default_shell()) != NULL && *p != NUL) #endif ) #if defined(MSWIN) { // For MS-Windows put the path in quotes instead of escaping spaces. char_u *cmd; size_t len; if (vim_strchr(p, ' ') != NULL) { len = STRLEN(p) + 3; // two quotes and a trailing NUL cmd = alloc(len); if (cmd != NULL) { vim_snprintf((char *)cmd, len, "\"%s\"", p); set_string_default("sh", cmd); vim_free(cmd); } } else set_string_default("sh", p); } #else set_string_default_esc("sh", p, TRUE); #endif } /* * Set the default for 'backupskip' to include environment variables for * temp files. */ static void set_init_default_backupskip(void) { int opt_idx; int i; char_u *p; int plen; #ifdef UNIX static char *(names[4]) = {"", "TMPDIR", "TEMP", "TMP"}; #else static char *(names[3]) = {"TMPDIR", "TEMP", "TMP"}; #endif garray_T ga; opt_idx = findoption((char_u *)"backupskip"); ga_init2(&ga, 1, 100); for (i = 0; i < (int)ARRAY_LENGTH(names); ++i) { int mustfree = FALSE; #ifdef UNIX if (*names[i] == NUL) { # ifdef MACOS_X p = (char_u *)"/private/tmp"; plen = (int)STRLEN_LITERAL("/private/tmp"); # else p = (char_u *)"/tmp"; plen = (int)STRLEN_LITERAL("/tmp"); # endif } else #endif { p = vim_getenv((char_u *)names[i], &mustfree); plen = 0; // will be calculated below } if (p != NULL && *p != NUL) { char_u *item; size_t itemsize; int has_trailing_path_sep = FALSE; if (plen == 0) { // the value was retrieved from the environment plen = (int)STRLEN(p); // does the value include a trailing path separator? if (after_pathsep(p, p + plen)) has_trailing_path_sep = TRUE; } // item size needs to be large enough to include "/*" and a trailing NUL // note: the value (and therefore plen) may already include a path separator itemsize = plen + (has_trailing_path_sep ? 0 : 1) + 2; item = alloc(itemsize); if (item != NULL) { // add a preceding comma as a separator after the first item size_t itemseplen = (ga.ga_len == 0) ? 0 : 1; size_t itemlen; itemlen = vim_snprintf((char *)item, itemsize, "%s%s*", p, (has_trailing_path_sep) ?
