#eidolon ##Introduction A image gallery service written in Haskell as a yesod webapp. Visit the test instance at [eidolon.nek0.eu][eidolon] ##Installation ###Dependencies A working Haskell capable environment. For that you will need `ghc` and `cabal-install`. update your package list with `cabal update` and upgrade `cabal-install`, if necessary. Additionally to Haskell and its dependencies you will need the following software and libraries: * alex * happy * libmagick++-dev ###Building get the source with ```bash git clone https://github.com/nek0/eidolon.git ``` It's generally a good idea to create a sandbox for compiling. To do so `cd` into the project directory and invoke ```bash cabal sandbox init ``` Then install all dependencies with the following command. This may lead you into dependency hell, as I am working with very new libraries. ```bash cabal install --only-dependencies ``` After installing all dependencies you can configure and build the software with ```bash cabal configure cabal build ``` ##Deploying After compiling you will find an executable called `eidolon` in `dist/build/eidolon/`. Copy or link it anywhere you want. The executable needs to be accompanied by the folders `config` and `static` and their contents. It's best to copy them to your desired destination. Also check `config/settings.yml` and set the values there accrding to your configuration. It may also be necessery to create a reverse proxy to your gallery. I would recommend using [nginx](http://nginx.org/). ##Customizing Unfortunately the gallery is not highly customizable, but you can change most of its appearance by changing the files `static/css/static-*.css`. Especially the default background image can be changed by replacing `static/css/img/bg.jpg`. ##Starting You can start the gallery now by running the executable. You need to provide a settings file, normally found in `config/settings.yml` Since eidolon will block your console, I recommend wrapping a init-script around it. how you can do that is written in my [blog](http://nek0.eu/posts/2014-10-23-Daemonize-a-yesod-app.html). ##Migrations ###0.0.3-0.0.4 * do not start or restart your eidolon service before migration * run migration script from your run location (where your `static` folder with all the images is located) * if you are building in a sandbox run `runghc -package-db/full/path/to/sandbox/XXX-ghc-version-packages.conf.d /path/to/eidolon/Migrations/0.0.3-0.0.4/Migration.hs` * Note: No space between the option `-package-db` and its argument * without sandbox: `runghc /path/to/eidolon/Migrations/0.0.3-0.0.4/Migration.hs` * start or restart your eidolon service ##Acknowledgements: * This software uses the web Framework "Yesod" by Michael Snoyman.
