Everything is at http://apemost.sourceforge.net/. Papers pending ;-)

It basically has a “slot” for each file, you may think a queue of the blocks in this file, and tries to work its way through to the end of all queues. So it takes from the slot with the smallest block, writes it to the output file, and refills the slot with the next queue element from that file.
It is a little more sophisticated, because instead of looking through all slots for the next smallest block, it actually juggles the slots (files) in a sorted manner.
I will definitely reuse this.

14712KB pdfjoin.tar.bz2 (with Ghostscript sources)

I programmed it in Python+Glade+GTK. It uses ghostscript as backend.
Unpack and run “python pdfjoin.py”.

I’ll make a Windows package sometime.

It originally moves pages according to a month/day/year scheme.

I just wanted to move all the pages to a subnamespace. Here is my script:

#!/usr/bin/perl
use strict;
use WWW::Mechanize;
use WWW::Mechanize::FormFiller;
use URI::URL;
# list with page names
my @urls = `cat liste.txt`;
my $agent = WWW::Mechanize->new( autocheck => 1 );
my $formfiller = WWW::Mechanize::FormFiller->new();
$agent->env_proxy();
print "Logging in ... \n";
$agent->get('http://myurl/wiki/doku.php?do=login');
$agent->form_number(7) if $agent->forms and scalar @{ $agent->forms };
$formfiller->add_filler( 'u' => Fixed => 'myadmin' );
$formfiller->add_filler( 'p' => Fixed => 'mypassword' );
$formfiller->fill_form( $agent->current_form );
$agent->submit();
print "Logging in done.\n";
my $n, my $o, my $p;
foreach (@urls) {
print $_;
( $n, $o ) = m/(.*):([^:]*)/;
$p = 'myprefix:';
if (length($n) == 0) {
$p = 'myprefix';
( $o ) = m/(.*)/;
}
print '=> ' . $p . '|' . $n . '|' . $o . "\n";
$agent->get( "http://myurl/wiki/doku.php?id=" . $_ . "&do=admin&page=pagemove" );
$agent->form_number(6) if $agent->forms and scalar @{ $agent->forms };
$formfiller->fill_form( $agent->current_form );
$formfiller->fill_form( $agent->current_form );
if (length($n) == 0) {
$formfiller->add_filler( 'nsr' => Fixed => '' );
$formfiller->add_filler( 'newns' => Fixed => $p );
$formfiller->add_filler( 'ns' => Fixed => $p );
} else {
$formfiller->add_filler( 'nsr' => Fixed => '<new>' );
$formfiller->add_filler( 'newns' => Fixed => $p . $n );
$formfiller->add_filler( 'ns' => Fixed => ':' );
}
$formfiller->add_filler( 'pagename' => Fixed => $o );
$formfiller->fill_form( $agent->current_form );
$agent->save_content("/tmp/mydump.txt");
$agent->submit();
$agent->save_content("/tmp/mydump-response.txt");
}

There existed a Converter and a Calculator extension, I made them work together.

Download: converterplus-1.9.tar (bz2, 9 KB) converterplus-1.8.tar (bz2, 6 KB)
Howto install:
You have to copy both files from the archive to ~/.gnome2/deskbar-applet/modules-2.20-compatible/, then activate them in the deskbar-applet Preferences.

Old versions of Converter and Calculator will not work together!
You can easily check if you got the right versions: They have my name as author in them and contain the line “This version of calculator can be used with converter” and vice versa.

You need to have the program units installed to benefit from Calculator. It is in your distribution’s repository under the name ‘units’.

Bugs: Please send bug reports by email or leave a comment here.

Technical details:
(users don’t need to read this)

The question was to either copy over the code from Calculator to Converter or to reuse the Module. Code duplication (DRY) was a definite argument against that. If Calculators code gets updated, Converter benefits too. Also, you can enable each functionality seperately.

Problem was to access the other module when loaded in deskbar, I made a hack for loading a file in the same directory, no matter of the context (see source).

This Python script converts it into a LaTeX-table (without \begin and \end):

table2latex.py:

#!/usr/bin/env python

import sys

f = sys.stdin

if(len(sys.argv) < 2):

        print "First Argument is number of columns"

        sys.exit(1)

numcolumns = int(sys.argv[1])

borders = False

if len(sys.argv) > 2 and sys.argv[2] == "--with-borders":

        borders = True

i = 0

while True:

        for j in range(numcolumns):

                l = f.readline()

                if l == "":

                        sys.exit(0)

                if i == 0:

                        print "\\tablehdr{%s}" % l.strip(),

                else:

                        print "%s" % l.strip(),

                if j == numcolumns - 1:

                        print '\\\\'

                        if borders:

                                print '\hline'

                else:

                        print '&',

        i = i + 1

Use it like this (pipe in from stdin, first arg is column count):

[user@thiscomputer ~]$ seq 30 | python table2latex.py 3

\tablehdr{1} & \tablehdr{2} & \tablehdr{3} \\

4 & 5 & 6 \\

7 & 8 & 9 \\

10 & 11 & 12 \\

13 & 14 & 15 \\

16 & 17 & 18 \\

19 & 20 & 21 \\

22 & 23 & 24 \\

25 & 26 & 27 \\

28 & 29 & 30 \\

[user@thiscomputer ~]$ 

The second argument can be if borders should be used, i.e. \hline after each row.

Feed into stdin, await from stdout.
For example: python dbdesc.py < DATASCHEME > dbdesc.html

It isn’t perfect nor meant to be, but gives a good starting point for a documentation.

#!/usr/bin/python
import sys
import re
a = ''

continue
type = l[1]
if len(l)<3:
l.append('')
op = ""
if 'not null' in l[2]:       op = op + '!'
if 'primary key' in l[2]:    op = op + '1+P'
elif 'unique' in l[2]:       op = op + '1'
print """ <tr>

print """</html> """

CSS file dbdesc.css

table.dbdesc{	width: 40em;	border: 1px solid #080;	border-width: 1px 0;}
table.dbdesc th{	border-bottom: 1px solid #080;}
table.dbdesc td{	border: none;}
table.dbdesc td, table.dbdesc th{	width: 15em;}
table.dbdesc th{	font-style: italic;	font-weight: normal; }
table.dbdesc td.option{	text-align: center;}
table.dbdesc td.type{	text-transform: uppercase;}

I made a script able to export the history to html, as well as Python classes able to random-access the logs.

As far as I can see, I’m the first one on the net that did this, everyone else is sane and uses the API.
