Running a Vim macro on a set of lines with norm

提供了我們全文選擇，然後再在選中的行運行宏的辦法, normal 是個很有用的東西，其意義就是在command中運行一些norm model下的操作， 提供了我們很多組合操作的可能，拓展了使用vim的維度， 比如

:g/\/\// norm dd可以刪除所有的注釋程式碼。

It’s occasionally handy to be able to run a macro that you’ve got ready on aspecific subset of lines of the file, or perhaps just for every line.Fortunately, there’s a way to do this, too.

Using the :normal command, you’re able to run macros from the ex command line:

:normal @a

All it takes is prefixing this with any sort of
range definition to allowyou to run a macro on any set of lines that you’re able to define.

Run the macro on each line of the whole buffer:

:% normal @a

Between lines 10 and 20:

:10,20 normal @a

On the lines in the current visual selection:

:'<,'> normal @a

On the lines containing the pattern vim:

:g/vim/ normal @a

When you get confident using this, :norm is a nice abbreviation to use.
