| 112 SYM is the symbol being operated on (read, set, etc.); | |
| 113 | |
| 114 VAL is either the value to set or the value to be returned. | |
| 115 | |
| 116 IN_OBJECT is the buffer or console that the value is read in | |
| 117 or set in. A value of Qnil means that the current buffer | |
| 118 and possibly other buffers are being set. (This value will | |
| 119 never be passed for built-in buffer-local or console-local | |
| 120 variables such as `truncate-lines'.) (Currently, a value of | |
| 121 Qnil is always passed for DEFVAR_INT, DEFVAR_LISP, and | |
| 122 DEFVAR_BOOL variables; the code isn't smart enough to figure | |
| 123 out what buffers besides the current buffer are being | |
| 124 affected. Because the magic function is called | |
| 125 before the value is changed, it's not that easy | |
| 126 to determine which buffers are getting changed. | |

| 155 /* Used in a symbol value cell when the symbol's value is per-buffer. | |
| 156 | |
| 157 The type of the symbol-value-magic will be either | |
| 158 SYMVAL_BUFFER_LOCAL (i.e. `make-variable-buffer-local' was called) | |
| 159 or SYMVAL_SOME_BUFFER_LOCAL (i.e. `make-local-variable' was called). | |
| 160 The only difference between the two is that when setting the | |
| 161 former kind of variable, an implicit `make-local-variable' is | |
| 162 called. | |
| 163 | |
| 164 A buffer-local variable logically has | |
| 165 | |
| 166 -- a default value | |
| 167 -- local values in some buffers | |
| 168 | |
| 169 The primary place where the local values are stored is in each | |
| 170 buffer's local_var_alist slot. | |
| 171 | |
| 172 In the simplest implementation, all that this structure needs to | |
| 173 keep track of is the default value; to retrieve the value in | |
| 174 a buffer, look in that buffer's local_var_alist, and use the | |
| 175 default value if there is no local value. To implement | |
| 176 `make-local-variable' in a buffer, look in the buffer's | |
| 177 local_var_alist, and if no element exists for this symbol, | |
| 178 add one, copying the value from the default value. When setting | |
| 179 the value in a buffer, look in the buffer's local_var_alist, and set | |
| 180 the value in that list if an element exists for this symbol; | |
| 181 otherwise, set the default. (Remember that SYMVAL_BUFFER_LOCAL | |
| 182 variables implicitly call `make-local-variable' first, so when | |
| 183 setting a value, there will always be an entry in the buffer's | |
| 184 local_var_alist to set.) | |
| 185 | |
| 186 However, this operation is potentially slow. To speed it up, | |
| 187 we cache the value in one buffer in this structure. | |
| 188 | |
| 189 NOTE: This is *not* a write-through cache. I.e. when setting | |
| 190 the value in the buffer that is cached, we *only* change the | |
| 191 cache and don't write the value through to either the buffer's | |
| 192 local_var_alist or the default value. Therefore, when retrieving | |
| 193 a value in a buffer, you must *always* look in the cache to see if | |
| 194 it refers to that buffer. | |
| 195 | |
| 196 The cache consists of | |
| 197 | |
| 198 -- a buffer, or nil if the cache has not been set up | |
| 199 -- the value in that buffer | |
| 200 -- the element (a cons) from the buffer's local_var_alist, or | |
| 201 nil if there is no local value in the buffer | |
| 202 | |
| 203 These slots are called CURRENT-BUFFER, CURRENT-VALUE, and | |
| 204 CURRENT-ALIST-ELEMENT, respectively. | |
| 205 | |
| 206 If we want to examine or set the value in BUFFER and CURRENT-BUFFER | |
| 207 equals BUFFER, we just examine or set CURRENT-VALUE. Otherwise, | |
| 208 we store CURRENT-VALUE value into CURRENT-ALIST-ELEMENT (or maybe | |
| 209 into DEFAULT-VALUE), then find the appropriate alist element for | |
| 210 BUFFER and set up CURRENT-ALIST-ELEMENT. Then we set CURRENT-VALUE | |
| 211 out of that element (or maybe out of DEFAULT-VALUE), and store | |
| 212 BUFFER into CURRENT-BUFFER. | |
| 213 | |
| 214 If we are setting the variable and the current buffer does not have | |
| 215 an alist entry for this variable, an alist entry is created. | |
| 216 | |
| 217 Note that CURRENT-BUFFER's local_var_alist value for this variable | |
| 218 might be out-of-date (the correct value is stored in CURRENT-VALUE). | |
| 219 Similarly, if CURRENT-BUFFER sees the default value, then | |
| 220 DEFAULT-VALUE might be out-of-date. | |
| 221 | |
| 222 Note that CURRENT-VALUE (but not DEFAULT-VALUE) can be a | |
| 223 forwarding pointer. Each time it is examined or set, | |
| 224 forwarding must be done. | |

| 563 | 340 /* Defining symbols: |
| 341 | |
| 342 (1) A standard symbol is defined with DEFSYMBOL. That means that | |
| 343 the symbol's print name can be derived from the symbol's variable | |
| 344 name by removing the initial Q and replacing underscores with hyphens. | |
| 345 (2) A keyword symbol is defined with DEFKEYWORD. That means that | |
| 346 the symbol's print name can be derived from the symbol's variable | |
| 347 name by removing the initial Q and replacing underscores with hyphens, | |
| 348 except that the initial underscore, which comes directly after the Q, | |
| 349 is replaced by a colon. | |
| 350 (3) DEFSYMBOL_MULTIWORD_PREDICATE is used for the predicates that are | |
| 351 associated with a particular type of Lisp Object. Because of the | |
| 352 limitations of C macros, they're always given a predicate symbol | |
| 353 whose C name simply appends `p' to the type name, modulo hyphen/ | |
| 354 underscore conversion. Properly, however, the Lisp name should have | |
| 355 `-p' if there is more than one word in the type name. | |
| 356 DEFSYMBOL_MULTIWORD_PREDICATE is for these weird symbols -- the | |
| 357 C name as supplied to the macro should end with a `p' with no | |
| 358 underscore before it, and the macro will insert a hyphen there in | |
| 359 the Lisp name. | |
| 360 (4) In case you have some weird symbol where the equivalence between | |
| 361 the C and Lisp names is more complicated (e.g. the Lisp symbol has | |
| 362 non-alphabetic, non-numeric characters in it), you can just call | |
| 363 defsymbol() (the lowercase version) directly. | |
