HowTo Browsing the documentation while offline
1 The idea
For those users who run OpenFOAM on their laptop that is not always connected (or pc's without internet connection or with a slow internet connection and similarly), here are some instructions for setting it up. The idea is to install a webserver on your pc (apache webserver) together with php. The following instructions worked out for OpenFOAM-1.4.1-dev and Suse 10.3:
2 Instructions for browsing the Doxygen documentation offline
1) Figure out how to install apache with php on your preferred OS (I personally used Suse YAST-tool and cannot completely remember what I chose, but if in doubt try to pick something with apache / webserver / php5 and install it).
2) Test that the webserver works: Try entering "localhost" and/or 127.0.0.1 in your favourite web-browser. You should see a webpage saying something about "This works" and/or an "advertisement for the apache server" or similar. You can be sure that something is wrong if a 404 error (webpage not found) appears. If that is the case, try running "/etc/init.d/apache2 --restart" (works for me in Suse) to shutdown httpd, re-read configuration files and start the server (daemon) up again.
3) Assuming apache/the webserver works: Go to $WM_PROJECT_DIR/doc. Then issue: "./Allwmake" unless you're sure the documentation is already there. In my case I have "Guides-a4"- and "Doxygen"- subdirectories residing here. Inside the "Doxygen"-subdirectory, there should be an "html"-subdir with a lot of files. These files are the ones we need...
4) Now you need to modify the "documentroot"/"directory" settings in your apache configuration file(s). In my case I modified a "default-server.conf" file residing in /etc/apache2 (suggestions and improvements are welcome - I don't know much about apache). You need to tell where the webserver files are locally:
DocumentRoot "/home/martin/OpenFOAM/OpenFOAM-1.4.1-dev/doc/Doxygen/html"
If in doubt, steal my configuration file below... "Options FollowSymLinks" must be enabled but you'll figure this out if everything works and you click somewhere and see an error message about some path or file that couldn't be found (or access denied or similar).
5) In order to solve the problem with Doxygen linking to C source files which it couldn't find, do this: Add a symbolic link in ~/OpenFOAM/OpenFOAM-1.4.1-dev/doc/Doxygen/html to
/home/martin/OpenFOAM/OpenFOAM-1.4.1-dev/src. In linux just copy/paste this line (because apache seem to work with relative paths):
ln -s /home/martin/OpenFOAM/OpenFOAM-1.4.1-dev/src ~/OpenFOAM/OpenFOAM-1.4.1-dev/doc/Doxygen/html/src
6) The content type (MIME-type) of the C-source files were in my case recognized as "text/C source file" so whenever I clicked on a source file, my browser asked me what to do with the file (download / save as etc.). I find that very annoying, so this is the fix I came up with: Add "AddType text/plain C c CPP cpp" to your apache configuration file (or steal or get inspired by my conf-file below).
7) If I didn't forgot anything and you modified your Documentroot/Directory settings properly, you should now be able to restart your apache-webserver - on my system: "/etc/init.d/apache2 --restart". Verify that you'll see some OF documentation when you enter "localhost" and/or 127.0.0.1 (not sure about if caching is a problem here - perhaps on some systems but not on mine?).
Also verify that when you enter something in the "search" field an type enter, then you should *NOT* see a popup asking whether you want to open the ".php" file or save it. I hope I didn't forget to mention anything - I don't know much about apache and/or php so please correct these instructions if something can be improved. And good luck with the off-line browsing of the documentation (doesn't some people say: "happy browsing"?).
