Heraclitus Fire

Description

This project retrieves histories of schemata that have been processed on how the schema and the individual tables evolve and automatically produces visualizations and statistical tests for patterns of schema evolution

Installation

1. Install Java (jdk-13 is used) The folder /lib comes with all the jar needed for the software to work. A point of possible pain is the handling of JavaFX: all javaFx libs are included. Although not thoroughly tested, Java 8 should probably work, too.

Usage

Must configure correctly the paths for

• java executable
• javafx lib
• location of the target HeraclitusFireRunable jar Then, you can massively work with multiple data sets, nested under the same 'mother' folder as follows.

For shell, cd to the 'mother' folder, edit the aforementioned variables in the following script and run it

#!/bin/sh
usage()  
{  
	echo "Usage: $0 projectFolder \n\t assuming you are at the mother folder of projectFolder "  
 	exit 1  
} 

libpath="/home/pvassil/bin/javafx-sdk-13/lib"
runnableJar="./HeraclitusFireRunable_v0-4-3.jar"
echo libpath is: $libpath
echo runnableJar is: $runnableJar
echo

Xvfb :92 -screen 0 1024x768x16 &> xvfb.log &
export DISPLAY=:92.0

for D in *; do
    if [ -d "${D}" ]; then
	echo "${D}/"   
        java --module-path "$libpath" --add-modules "javafx.controls"   --add-exports javafx.controls/com.sun.javafx.charts=ALL-UNNAMED  -jar "$runnableJar" $D
     fi
done

For DOS, cd to the mother folder, edit the aforementioned variables and paste into the cmd prompt line.

for /d %i in (.\*) 
do (
"C:\Program Files\Java\jdk-13\bin\java" --module-path "C:\\Program Files\\Java\\JavaFX\\javafx-sdk-12.0.1\\lib" --add-modules "javafx.controls"  --add-exports javafx.controls/com.sun.javafx.charts=ALL-UNNAMED -jar ./HeraclitusFireRunable_v0-4-3.jar %i
)
