255 | |
256 | When called from lisp, this function takes two arguments TOP and | |
257 | BOTTOM, describing the current region. TOP must be before BOTTOM. | |
258 | The optional third argument MACRO specifies a keyboard macro to | |
259 | execute. | |
260 | ||
261 | This is useful for quoting or unquoting included text, adding and | |
262 | removing comments, or producing tables where the entries are regular. | |
263 | ||
264 | For example, in Usenet articles, sections of text quoted from another | |
265 | author are indented, or have each line start with `>'. To quote a | |
266 | section of text, define a keyboard macro which inserts `>', put point | |
267 | and mark at opposite ends of the quoted section, and use | |
268 | `\\[apply-macro-to-region-lines]' to mark the entire section. | |
269 | ||
270 | Suppose you wanted to build a keyword table in C where each entry | |
271 | looked like this: | |
272 | ||
f1180544 | 273 | { \"foo\", foo_data, foo_function }, |
63c86e17 JB |
274 | { \"bar\", bar_data, bar_function }, |
275 | { \"baz\", baz_data, baz_function }, | |
276 | ||
277 | You could enter the names in this format: | |
278 | ||
279 | foo | |
280 | bar | |
281 | baz | |
282 | ||
283 | and write a macro to massage a word into a table entry: | |
284 | ||
285 | \\C-x ( | |
286 | \\M-d { \"\\C-y\", \\C-y_data, \\C-y_function }, | |
287 | \\C-x ) | |
288 | ||
289 | and then select the region of un-tablified names and use | |
2b1c8da0 | 290 | `\\[apply-macro-to-region-lines]' to build the table from the names." |
