I’m writing a tokenizer in Python and found out a great GUI debugger for Regular Expression. For all of you that have been looking for a good Python Regular Expression GUI, you can depend on this - named Kodos:

Kodos is a Python GUI utility for creating, testing and debugging regular
expressions for the Python programming language. Kodos should aid any
developer to efficiently and effortlessly develop regular expressions in
Python. Since Python’s implementation of regular expressions is based on
the PCRE standard, Kodos should
benefit developers in other programming languages that also adhere to the
PCRE standard (Perl, PHP, etc…).

You can download and try it here

Here are the steps that I managed to install Mapnik 0.5.1 on Slackware 12.1, it’s for personal documentation but might be helpful for some of you out there.

Depends on your current installed packages, you may be required to install some other packages, for details of the dependencies, please refer to it’s wiki

Mapnik requires the Boost libraries, International Components for Unicode, Freetype, Proj4, and a variety of image libraries.

Installing Boost is often new to mapnik users, but the majority of remaining dependencies are more familiar.

If you have previously built or installed other open source graphics or mapping applications it is likely that most of the remaining dependencies are already installed.

Currently detailed notes on mapnik dependencies are included in each platform specific installation instructions.

See MapnikInstallation for more information.

Before installation, check your boost lib compatibility here
The boost lib I got from LinuxPackages.Net for Slackware 12.1 is at version 1.36, which is not compatible with mapnik 0.5.1 (I got error while compiling), so I took boost version 1.35 from here

- Install boost lib package
- Install scons package (from slacky.eu), requiredbuilder (from stabellini.net )
- Download SlackBuild of Mapnik for Slackware 12.1 from slacky.eu , put everything in the same folder (e.x /home/download/mapnik-slackbuild/)
- running #./mapnik.SlackBuild
- If everything is ok, you will get mapnik package at the same folder with the slackbuild scripts, install it like other Slackware packages.

Test your Mapnik:

Once the installation is completed, you can test your installation by running a Python Hello World with Mapnik (You can see detailed instruction from here). Here is my summarization

1. Download the data, put it in /home/work/mapnik/data/ & unzip it
2. Copy the python code below, put in it a file name world.py at /home/work/mapnik/

#!/usr/bin/env python

from mapnik import *
m = Map(600,300,“+proj=latlong +datum=WGS84″)
m.background = Color(’steelblue’)
s = Style()
r=Rule()
r.symbols.append(PolygonSymbolizer(Color(‘#f2eff9′)))
r.symbols.append(LineSymbolizer(Color(‘rgb(50%,50%,50%)’),0.1))
s.rules.append(r)
m.append_style(‘My Style’,s)
lyr = Layer(‘world’)
lyr.datasource = Shapefile(file=‘/home/work/mapnik/data/world_borders’)
lyr.styles.append(‘My Style’)
m.layers.append(lyr)
m.zoom_to_box(lyr.envelope())
render_to_file(m,‘world.png’, ‘png’)

3. Go to /home/work/mapnik/ and run the script #python world.py, if you get the world.png file in the same folder then everything is fine, mean the installation was successful
