This means a complete re-install.

This means I'm going to be offline for some time.

This is more an entry for future reference

In Karmic the version of nanoblogger will be 3.4. So I figured, why wait? I currently have some time, lets try to upgrade nanoblogger.

Also another nanoblogger user mailed me, saying 3.4 was three times faster... but with all my custom tweaks for 3.3 I'm hoping for the best.

With some packaging foo (had to install quilt and debhelper from Karmic), I now have a nanoblogger package for Jaunty (dpkg-source, dpkg-buildpackage and dpkg are your friends).

 sudo dpkg -i nanoblogger_3.4-1_all.deb

OKay, no errors, only one config question....

nb -l

still works.

nb -l cat

still works (looks to be sorted differently).

Just to be sure, lets make a small backup:

cp -rap miek.nl /tmp/backup-miek-nl

And now

nb -u

I'm seeing sed: -e expression #1, char 207: unterminated s command, but I have no idea where to look to fix this. Also I'm not getting the feeling that this is not so much faster than version 3.3: My zsh tells me it took this long:

313.27s user 517.06s system 687.68s elapsed 120%CPU (nb -u)

A quick reload on my homepage... it's looking good except the 'recent articles' is kaput, some css issues.

Finally the complete upgrade

nb -u all

also works.

Bug fixing

It looks like $NB_ArticleLinks is now done differently, so I need to update the templates a bit. The $NB_ArticleLinks now needs to be properly wrapped in a sidetitle div.

Different stuff

Adding a new entry now must be done as follows:

nb -a entry -c 7

Which is slightly different in 3.3

Now the default html of visitors is nice, but I wanted to integrate it with my default website theme. Unfortunately visitors does not have the option to generate bare html. So Perl and shell to the rescue!

Stripping the style sheet

The html as generated by visitors include the following style sheet:

<style>
td {
    font-size: 10px;
    padding: 0;
}
.barfill {
    background-color: #96ef94;
    border-left: 1px;
    border-right: 1px;
... /* and more */
</style>

No I wanted to strip this using Perl and its marvelous flipflop (..) operator. 

1 int main(int c) {
2     printf("This is nice");
3     exit(1);
4 }

Line 5. shows the flip-flop operator in action. The ..-operator becomes true when <style> is seen (and stays true!) and becomes false when </style> is seen. Sort of like a state machine in one line of code. So if I find that I'm between the two style-tags in the file I don't print anything except for the first time (line 6). Then I insert my own modified style sheet.

header and footer

I also need to insert my own header and footer, this can be easily done with some here documents in the shell. And some annoying tags need to be stripped: sed to the rescue:

visitors -T -A -P http://www.miek.nl \
/var/log/apache2/miek.nl-access.log | \
sed -e 's/^<html>//' -e 's/^<hea d>//' \
-e 's/^<body>//' -e 's|^</head>||' \
-e 's|</body>||' -e 's|</html>||' -e 's/\[//'

Note that to keep everything consistent I use m4 to generate templates, these templates get converted to html and those are then used by nanoblogger.

Complete script

So the complete script for use in my site becomes:

#!/bin/zsh
# make a nice visitors page for use on miek.nl

( cat <<HEADER
...insert my header here...
HEADER

# create the content
visitors -T -A -P http://www.miek.nl \
/var/log/apache2/miek.nl-access.log | \
sed -e 's/^<html>//' -e 's/^<hea d>//' \
-e 's/^<body>//' -e 's|^</head>||' \
-e 's|</body>||' -e 's|</html>||' -e 's/\[//'

cat <<FOOTER
...insert my footer here...
FOOTER
) | perl -we '
# now fix the css style in the m5 file
# remove it completely and replace it with my own
my $printed = 0;
while (<>) {
if (m|<style>| .. m|</style>|) {
    system("cat /home/miekg/bin/visit.style") if !
    $printed;
    $printed = 1;
    } else {
    print
    }
}' > /home/miekg/miek.nl/server/visit.m5
# build the html, finally!
( cd /home/miekg/miek.nl; make -f m5.Makefile server/visit.html )

I must say, it really helps (for now). I've also made the rdup mailing list subscriber only, because I was fed up with deleting email from the mailman's non-subscriber queue. I.e. non-subscriber email is now discarded.

When giving a comment you can click 'Notify me of followup comments by email'. Each approved comment will then be mailed to the email address given. This will of course only happen until the commenting is closed on this entry.

Doing so will get you these kind of email messages:

Subject: Comment notify miek.nl `Windows 7?'
To: miek@miek.nl
Date: Tue, 21 Apr 2009 11:05:27 +0200 (CEST)

Hello,

This is an email to inform you of a new comment
at http://miek.nl.
It is posted under the blog entry titled `Windows 7?'

<a href="http://miek.nl">Miek Gieben</a>
Hallo

--
Comment notify sent by http://miek.nl - Tue Apr 21 11:05:27 CEST 2009
Notifies will be sent until commenting is closed

The only thing not implemented is a direct link to the blog entry with the new comment. It is doable to recreate the original URL, but for now this is sufficient.

Stuff on the todo: check if the email address is valid (syntax wise) and make it easy to remove someone from the notification list.
