Hurray! I finally got around to hacking a little script for vim that will automatically track posting dates for pyblosxom entries. It does the following:

1. For new entries, add '#mdate {currentdate}' on the 2nd line.
2. For existing entries without '#mdate' metadata, it will look up the mdate of the current entry and append it in the form, '#mdate {mdate of file}'
3. After you write (:w, :wq, etc), vim will look for #mdate metadata and turn the date into something touch(1) can use, then set the modification date of the file.

This seems to work pretty well, and is quite transparent to pyblosxom, since it sees lines beginning with #foo as "metadata" - so far so good. However, it does jump to the 2nd line of the file when you save, which is annoying (but fixable). I'll fix that later.

My "vim scripting"-fu is not strong, so there's probably a cleaner/fancier way to do this. Anyhoo, you'll need the following in your .vimrc:

" PyBlosxom stuff
augroup pyblosxom
	autocmd BufReadPost /home/jls/public_html/entries/*/*.txt call Pyblosxom_checkdate()
	autocmd BufNewFile /home/jls/public_html/entries/*/*.txt call Pyblosxom_putdate()
	autocmd BufWritePost /home/jls/public_html/entries/*/*.txt call Pyblosxom_fudgedate()
augroup end

function Pyblosxom_checkdate() 
	" Look in the file for '#mdate foo' metadata
	normal 1G
	let dateline = search("^#mdate")

	" If not found, append the mdate of the file to line 2
	if dateline < 1
		let dateline = 1
		let date = system("stat -f '#mdate %Sm' " . expand("%"))

		" Add the date to the file on line 1
		1put=date
	endif
endfunction

function Pyblosxom_putdate()
	let date=strftime("#mdate %b %e %H:%M:%S %Y")
	1put=date
	goto 1
endfunction

function Pyblosxom_fudgedate() 
	let l=search("^#mdate")
	let l=strpart(getline(l), 7)
	let cmd="date -j -f '%b %e %H:%M:%S %Y' '" . l . "' +%y%m%d%H%M"
	let touchtime=system(cmd)
	let touchcmd="touch -t '" . strpart(touchtime,0,strlen(touchtime)-1) . "' '" . expand("%") . "'"
	call system(touchcmd)
	e
endfunction

nfsstat | sed -ne '/Version 3/,/^$/p'

sed++

When I was bored (at 4 am, no-less), I kept trying to parse this information out using some crazy tricks with 'x' (swap pattern/hold) and other stuff, but I forgot the fact that regexps are valid addresses. So, we can print anything between 'Version 3' and blank lines, anywhere in our output.

The next thing I want to try with this is to automagically parse nfsstat output into a format that is more machine readable, this will probably be using awk or perl, seeing as how doing it with sed may hurt my brain a bit. Furthermore, trying to read the sed that did said operations would be somewhat intense ;)

The output looks something like this, on Solaris 9:

Version 3: (535958 calls)
null        getattr     setattr     lookup      access      readlink    
0 0%        242223 45%  20606 3%    52504 9%    20025 3%    41 0%       
read        write       create      mkdir       symlink     mknod       
14138 2%    146618 27%  5525 1%     145 0%      337 0%      0 0%        
remove      rmdir       rename      link        readdir     readdirplus 
6279 1%     7 0%        1539 0%     1518 0%     1606 0%     6587 1%     

Parsing this would mean generating a tree-like dictionary. In perl, it may look like:

%foo = (
	'Version 3' => {
		null => 0,
		getattr => 242223,
		setattr => 20606,
		lookup => 52504,
		# .... etc ...
		}
	)

Should be simple enough, we'll see what happens next time I get bored.
