Place this application into a directory where cgi-scripts are evaluated.
If you want to change some configuration, state it in the file
config_sample.rbfor help) to start with a default configuration.
The webserver needs the permission to write into the directory
.mofiles in order to use localisation. You have 2 possibilities:
Run this small script to fetch the files from the main server:
cd $DUDLE_INSTALLATION_PATH for i in locale/??; do wget -O $i/dudle.mo https://dudle.inf.tu-dresden.de/locale/`basename $i`/dudle.mo done
Build them on your own. This requires gettext, ruby-gettext, potool, and make to be installed.
sudo aptitude install ruby-gettext potool make make
In order to let access control work correctly, the webserver needs auth_digest support. It therefore may help to type:
sudo a2enmod auth_digest
In order to get atom-feed support you need ruby-ratom to be installed. E.g.:
sudo aptitude install ruby-dev libxml2-dev zlib1g-dev sudo gem install ratom
To make titles with umlauts working you need to check the encoding in .htaccess, e.g.
SetEnv LC_ALL "en_US.UTF-8"
It might be the case, that you have to set some additional Variables in your .htaccess:
SetEnv GIT_AUTHOR_NAME="http user" SetEnv GIT_AUTHOR_EMAILemail@example.com SetEnv GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME" SetEnv GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"
If you installed dudle to a subdirectory (i.e. http://$YOUR_SERVER/$SOMEDIR/...), than you want to adopt the ErrorDocument directives in your .htaccess. (You need an absolute path here!)
Try to open http://$YOUR_SERVER/check.cgi to check if your config seems to work.
You may want to install a cronjob to cleanup dudle polls. See dudle_cleanup.sh for an example.
You can enable a maintenance mode if you need to change something with your installation. Using this mode, all users will see a static message and are not able to change anything. In order to enable this mode, create a file named
/maintenance.htmlwhich may include a custom message. E.g.:
echo "<div>We are updating the servers and expect to be online on 0 am, January 1st, 1970 (UTC).</div>" > $DUDLE_INSTALLATION_PATH/maintenance.html
There is a docker image available
Pimp your Installation
- If you want to create your own Stylesheet, you just have to put it in
$DUDLE_HOME_FOLDER/css/. Afterwards you may config this one to be the default Stylesheet. Examples can be found here:
- If you want to extend the functionality you might want to place a file
$DUDLE_HOME_FOLDER/extension/$YOUR_EXTENSION/main.rbExamples can be found here: https://dudle.inf.tu-dresden.de/extensions/ You can clone the whole sourcecode here:
- https://github.com/kellerben/dudle-extensions-anonymous Note, that extensions are loaded in alphabetic order! The symcrypt extension e.g. needs the participate extension and therefore you need to name it “10-participate” in order to get executed first.
If you set
$DUDLE_POEDIT_AUTO to your lang, poedit will launch
automatically when building the application. E.g.:
export DUDLE_POEDIT_AUTO=fr git pull make # will launch poedit if new french strings are to be translated
- To add a new translation
- first add a new folder for your language under $DUDLE_HOME_FOLDER/locale,
- copy the dudle.pot file into your folder and name it dudle.po
- translate sentences and phrases in your dudle.po file
- add an entry for your language in dudle/dudle.rb at line 245
