"Apply last keyboard macro to all lines in the region.
|
|
For each line that begins in the region, move to the beginning of
|
|
the line, and run the last keyboard macro.
|
|
|
|
When called from lisp, this function takes two arguments TOP and
|
|
BOTTOM, describing the current region. TOP must be before BOTTOM.
|
|
The optional third argument MACRO specifies a keyboard macro to
|
|
execute.
|
|
|
|
This is useful for quoting or unquoting included text, adding and
|
|
removing comments, or producing tables where the entries are regular.
|
|
|
|
For example, in Usenet articles, sections of text quoted from another
|
|
author are indented, or have each line start with `>'. To quote a
|
|
section of text, define a keyboard macro which inserts `>', put point
|
|
and mark at opposite ends of the quoted section, and use
|
|
`\\[apply-macro-to-region-lines]' to mark the entire section.
|
|
|
|
Suppose you wanted to build a keyword table in C where each entry
|
|
looked like this:
|
|
|
|
{ \"foo\", foo_data, foo_function },
|
|
{ \"bar\", bar_data, bar_function },
|
|
{ \"baz\", baz_data, baz_function },
|
|
|
|
You could enter the names in this format:
|
|
|
|
foo
|
|
bar
|
|
baz
|
|
|
|
and write a macro to massage a word into a table entry:
|
|
|
|
\\C-x (
|
|
\\M-d { \"\\C-y\", \\C-y_data, \\C-y_function },
|
|
\\C-x )
|
|
|
|
and then select the region of un-tablified names and use
|
|
`\\[apply-macro-to-region-lines]' to build the table from the names."
