##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 exe:eidolon
|
|
```
|
|
|
|
##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
|
|
* build the Migration script with `cabal build Migration1`
|
|
* Migration script is located in `dist/build/Migration1/` in your build directory
|
|
* run migration script from your run location (where your `static` folder with all the images are located)
|
|
* start or restart your eidolon service
|
|
