RReportGenerator on the Web

RReportGenerator is also available through a web interface.

How it works

The main tcl program rrg.tcl, written by Luc Moulinier, remains nearly unchanged. We replaced the call to 'main' with following lines :

global env
if {! [info exists env(QUERY_STRING)] && $argv=={}} {
    package require Tk
    main
} else {
    source "[file dirname [info script]]/rrg_web.tcl"
    MainWeb
}

• (We should find a better way to test if it concerns http ...)
• If launched as local program, rrg.tcl requires the package Tk and runs normally
• If launched by the web server, rrg.tcl sources the additional file rrg_web.tcl and sends a html page to the web browser.
• Any action from the user through his web browser will rerun rrg.tcl, the arguments are always transfered within the web page and users queries, avoiding use of session variables.
• The user can switch between existing projects (if he knows the password) or create a new project.
• Within a project he can select, delete or create scenarios and input files.
• After selection of a scenario and input file the user can run RReportGenarator. This lauches the normal rrg.tcl from Luc and stores the result in the OutputDir of the project.
• These output files can be shown, downloaded and deleted by any user knowing the password of the project.

Installation

To run RreportGenerator on the Web you need

1. A http web server (we use Apache)
2. An already installed RReportGenerator
   1. with the files rrg.tcl and rrg_web.tcl or their binary version
   2. the logos RRG_logoTransparent.gif, RRG_generateReport.gif
   3. access to R, latex and pdflatex

Where have the files to be located

• rrg.tcl rrg_web.tcl and the logos have to be in the same directory accessible by the web server (if not in the same directory you can use unix links to simulate it)
• in the same directory must exist a sub directory called Web which will contain the scenarios, input and ouput files for all projects. (use links if they are elsewhere)
