As part of my passion for ASCII art, I've found another interesting tool useful to ASCII art maniacs like me, the tool is called ditta and is able to convert manually drawn ASCII art diagrams to graphics, below is tool description from my debian apt-cache as well as a screenshot:

 apt-cache show ditaa|grep -i ditaa -A 4

Package: ditaa
Priority: optional
Section: graphics

 DiTAA is a small command-line utility that can convert diagrams drawn using
 ASCII art ("drawings" that contain characters that resemble lines, like | /
 and -), into proper bitmap graphics.
 DiTAA also uses special markup syntax to increase the possibilities of shapes
 and symbols that can be rendered.


To install ditaa on Debian and Ubuntu Linux:

debian:~# apt-get install --yes ditaa

Ditaa text diagram to Graphics converter is also available in Fedora Linux and in Source RPMs to be used on Redhat Based RPM distributions.
To install in most of RPM based Linuxes:

[root@fedora:~]# yum install -y ditaa

For most people probably Ditta will not be of any value except as a PoC and of a Hack value just like Ditaa's home page suggests. Nomatter that Ditta is cool but has just 2 drawback it doesn't understand non-latin characters i.e. Cyrillic and requires Java Virtual Machine .. but if you're a real geek you will do  the sacrifice to install a whole bunch of the heavy java for the sake of some oldschool fun 🙂 Being written in Java makes Ditta multi-platform, but you will need a Java VM version of at least 1.6 (it doesn't work with Java 1.5).

The format Ditta understands is close to HTML

<ditaa [optional parameters]>
... (some ditaa-code) ...

There are also special tags understood by Ditta which are automatically turned into shaped graphical buttons and forms.

Possible tags

Not all shape selector tags are documented on the ditaa site. A quick source scan revealed:

tag Description
{c} decision(Choice)
{d} document
{io} input/output, parallelogram
{mo} manual operation
{o} ellipse, circle
{s} storage
{tr} trapezoid (looks like an inverted {mo} )

Here is an example Ditta code

<ditaa round noedgesep right>
    +--------+   +-------+    +-------+
    |        | --+ ditaa +--> |       |
    |  Text  |   +-------+    |diagram|
    |Document|   |!magic!|    |       |
    |     {d}|   |  c478 |    |       |
    +---+----+   +-------+    +-------+
        :                         ^
        |       Lots of work      :

This Ditta code will generate following picture:

Today I have Marketing exam. Ofcourse as usual when I have exams I haven’t studied enough, and again I’m in the situation realizing I don’t know anything. I depend 100% on God’s grace to take that exam. Why I’m so dumb never study when

I have what I have. I can’t change my self I can’t study something I’m not interested into. Marketing is a subject which is simple but for Jerks IMHO :]. The logic of marketing is too abstract.

And yes what’s happening with me the last days. Well I’m feeling good now Praise the Lord. I’ve no idea what I should do with my life. I have 2 re-exams for now or maybe 3 ( I don’t know the results from the Research & Statistics Exam ).

The last few days I ran FreeDOS and Windows 2000 Pro SP4under FreeBSD 6.2 with qemu. FreeDOS’s performance is very nice despite the fact it is emulated. The Windows is running a little laggish although I ran it with kqemu ( Experimental Module for qemu which enhances the typical qemu speed ). Yesterday we drink a dark beer with Nomen into the “Happy Person” Pub. My passion for computers is starting to come back again.
