save and load a micro

[Sand Glass]

I will often do the following things next days.
So I want to record the commands as a macro. But I don't know how to save the macro to a file and load the macro next time, so that I open a file just hit a key, can do the repeat things.

I have done the thing use following commands.
GkVjdggww^QjjjjjjjjjjjjjjjjjI,0x^[5l.ww.5l.ww.5l.ww.5l.ww.5lwhhhhl.ww.5l.ww.5l.ww.5.u5l.el.l^QjjjjjjjjjjjjjjjjDjjjjjjjjjjjjjjjx0gg^Qjjjjjjjjjjjjjjjjjjjjelllx
And record a macro in register a. But the macro not completely right like ^Q(it's into block coloumn mode). I want to fix my macro and save it to a file, next time I open a file can load the macro to a reg.
The question is I don't how to fix my macro and load it to a reg next time.

By default, it should be saved already, in your .viminfo file. Check your 'viminfo' setting to make sure if you are worried.

You can also paste the contents of your register into a file with this normal-mode command:

"ap

Then you can save that file if you like. To get your macro back, just yank the content back into a register:

0"ay$

This may not work in all cases for special characters in the register, etc. The .viminfo method is probably more robust.

[Nikolay Aleksandrovich Pavlov]

For robust keeping register in a file one should use
`writefile([getregtype('a')] + getreg('a', 1, 1), 'rega', 'b')`. For
restoring then: `let rega = readfile('rega', 'b') | setreg('a',
rega[1:], rega[0])`.

Thanks for ZyX.
The finial command is following:
qa "start recording to reg a
"do your command
q "end recording
:call writefile([getregtype('a')] + [getreg('a', 1)], 'rega.txt', 'b')
:let rega = readfile('rega.txt', 'b')
:call setreg('a', rega[1], rega[0])
@a "play the macro
