Configuration variables
I'm used to setting config variables before I include the extension PHP file. Please consider changing the code to not define the variables in the extension and requiring them to be set in LocalSettings.php in advance. I also think there should be another config variable that can be used to set the GDFONTPATH environment variable. Maybe use $wgGnuplotGDFontPath and do the export in the extension before executing the gnuplot shell command. --Dmulter 18:35, 12 March 2009 (UTC)

Gérard 09:18, 15 March 2009 (UTC) Thanks for your comment. The way this extension works with its settings is inherited from the two extensions it is based upon. If you know of an other extension that handles config variables the way you suggest I'll look in to it. Are you interested in using this extension?

Take a look at BugzillaReports and BugMilestone. The latter being a simpler one. I'm using the extension now and it works great. I'm still working on getting it to find my TTF fonts via GDFONTPATH. Should figure it out soon. --Dmulter 16:49, 25 March 2009 (UTC)

I finally figured out the font path problem. There are probably other ways to solve it, but here's my approach. I set the GD environment variables in my Apache httpd.conf file. Unfortunately the extension does a shell_exec that creates a subprocess that does not inherit any environment variables, so they are not passed to the Gnuplot command. I added 4 lines to the extension code to force the process to use my variables. Here's the existing code with the 4 new lines. Please consider adding this to the extension. // execute the gnuplot command $cmdlinePlot = $wgGnuplotCommand. ' ' . $fname; $gdpath = getenv("GDFONTPATH"); putenv("GDFONTPATH=$gdpath"); $gdpath = getenv("GNUPLOT_FONTPATH"); putenv("GNUPLOT_FONTPATH=$gdpath"); shell_exec($cmdlinePlot); --Dmulter 18:26, 25 March 2009 (UTC) Thanks for your work. I added the environment variable setting to the new version 0.9.4 Although I am not sure why getting- and setting them just before the shell_exec helps the created subprocess to find them. I am running under Windows and do not set the environment variables at all. Gérard 12:16, 27 March 2009 (UTC)
