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
- A http web server (we use Apache)
- An already installed RReportGenerator
- with the files rrg.tcl and rrg_web.tcl or their binary version
- the logos RRG_logoTransparent.gif, RRG_generateReport.gif
- access to R, latex and pdflatex
Where have the files to be located
- we need a directory accessible by the web server. We call it rreportgenerator
- rrg.tcl rrg_web.tcl and the logos have to be in that directory (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)
We can now use the url http://http_server/rreportgenerator/rrg.tcl
- To allow the execution of the .tcl as cgi-bin you need following line in the apache configuration file
ScriptAliasMatch ^/rreportgenerator/rrg.tcl /real/path/to/the/directory/rreportgenerator/rrg.tcl
- if you want to allow the url http://http_server/rreportgenerator
- create a file index.php in rreportgenerator with a redirection to rrg.tcl
