Requirements

ruby >=1.9
git >=1.6.5
ruby-gettext (for localization)
gettext, potool, make (optional, if you want to generate localization files)

Installation

Place this application into a directory where cgi-scripts are evaluated.
If you want to change some configuration, state it in the file config.rb (see config_sample.rb for help) to start with a default configuration.
The webserver needs the permission to write into the directory
You need .mo files in order to use localisation. You have 2 possibilities:
1. 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
```
2. 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 [email protected]
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.html which 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
```

image

There is a docker image available

https://github.com/jpkorva/dudle-docker

Pimp your Installation

If you want to create your own Stylesheet, you just have to put it in the folder $DUDLE_HOME_FOLDER/css/. Afterwards you may config this one to be the default Stylesheet. You can fetch the whole repo from https://github.com/kellerben/dudle-css
If you want to extend the functionality you might want to place a file main.rb in $DUDLE_HOME_FOLDER/extension/$YOUR_EXTENSION/main.rb You can clone the whole sourcecode here:
- https://github.com/kellerben/dudle-extensions-participate
- https://github.com/kellerben/dudle-extensions-symcrypt
- https://github.com/kellerben/dudle-extensions-asymcrypt
- https://github.com/kellerben/dudle-extensions-gpgauth
- 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.

Translators

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
