INSTALLATION INSTRUCTIONS To make the software work you will need a postgresql server version 9.1 or higher, and the data.txt file. Please do the following steps IN ORDER 1 - Unzip the release in the folder of your choice, not too deep in the filesystem, at least on windows. 2 - Check in the application.conf file that the values to connect to your instance of postgresql are correct. Adjust if needed. 3 - Start the Postgresql server. I used the default port 5432. 4 - In the bin folder, create a folder named "data" and put the unzipped data.txt file on it. The Path of the file should look like this: c:\<yourfolder>\hep-1.0-SNAPSHOT\bin\data\data.txt 5 - In the bin folder, launch hep or hep.bat depending on the OS. Go to the url "http://localhost:9000/tests". If all the tests have the value true, then you are ready to go and can start browsing at the address http://localhost:9000. If one line ends with "false", then one dependency has not been found and the website is not functional. In the event that the databse server is not running, the screen may be filled with a play stacktrace indicating that a connection could not be made. KNOWN BUGS/PROBLEMS - The datepicker displays some things in the browser language. - F5 during import will show the play button instead of the pause button - The count(*) request is horrendously slow using postgresql. - Javascript and css files are not minifed/obfuscated - Graphs do not fetch the data from the DB if you only change granularity. This is by design, but can be misleading during import. - The years you can choose from is populated either on page load, or, if empty, on first click and does not get refreshed after. Same misleading beahavior as above. TECHNICAL CHOICES Play has: - a known hierarchy of files, to makes reading code easier - a built-in packaging system - a built-in http server - a websocket handler - an ORM (not really used but still) Also, I wanted to learn how to use it. NOTES Tested on Firefox, Chrome and IE 11. Not tested on safari. I tried to chose the best balance between number of features, quality of code, and fun; I hope you agree with my choices.
