Command to generate GUID ?

[Timothy Madden]

Hello

I want to create my install packages with WiX in .wxs source files
edited with Vim.
For WiX I need to generate a new GUID for every new package I
distribute and every
major version of my program.

Could someone create a :command that would check the current selection or
the next 36 chararcters after the cursor to be hexadecimal digits
including minus
sign (anywhere in between) and then replace this text with the output
from a command
line executable (bin/GUIDGEN.exe) ?

Is there a script for this already ?

I do not know vim language, I am still learning the commands

Thank you,
Timothy Madden

Easy

:s/\%#[-[:xdigit:]]\{36}/\=`GUIDGEN`

Explanation:

:s substitute on current line
/ replace what?
\%# zero-width, current cursor position
[ start collection
- dash
[:xdigit:] (inside collection) hex digit
] end collection
\{36} repeat 36 times (i.e., multiply previous atom by 36)
/ replace by what?
\= expression
`GUIDGEN` the stdout of program GUIDGEN which is the PATH
(no flags) do it just once

See
:help :s
:help pattern.txt

Best regards,
Tony.

My vim says Invalid expression `wine GUIDGEN.exe` after I
type :Guidgen,
which I defined like this in ~/.vimrc:

command Guidgen :s$\%#[-[:xdigit:]]\{36}$\=`wine GUIDGEN.exe`

I have vim7.2 on Slackware.

I used $ instead of / in the search command because the path to
GUIDGEN
might someday contain a literal /.

I would also like to skip the first line of output
(reading Z:\home\adrian\GUIDGEN.exe) and then ignore the braces
around
the generated GUID, if possible

Thank you,
Timothy Madden

you might try

command Guidgen :s$\%#[-[:xdigit:]]\{36}$\=system('GUIDGEN.exe')

instead.
