Good lesson for me today: keep it simple ;-)

repeat replace many time on each line

2007-04-02 Thread Arnaud Bourree 
Hello,

I've Xml document with attribute likes:
foo=00 12 AF
I want to replace with:
foo=0x00 0x12 0xAF

I try:
%s/\%(\%(foo=\\)\@=\%(0x[0-9A-F]\{2\}\s\)*\)\@=\([0-9A-F]\{2\}\)/0x\1/g

It works fine for each first occurrence of each line but not on others
whatever I've put g option.
I have to use repeat manually until change is finish.

How can I do repeat?

Thanks,

Arnaud.

Somewhat more generally, the pattern above could be:

%s/\%(\%(foo=\\)\@=\%(\%(0x\)\?[0-9A-F]\{2\}\s\)*\)\@=\([0-9A-F]\{2\}\)/0x\1/g

which works both with and (repeatedly) without the /g flag.

I prefer when dealing with that many special characters to use the
very-magic form:

%s/\v%(%(foo\=)@=%(%(0x)?[0-9A-F]{2}\s)*)@=([0-9A-F]{2})/0x\1/g

... but that's obviously a matter of personal preference.

Thank you,

bob
