# ABOUT
This document is a step-by-step guide showing how to create and compile a simple gallery and get familiar with _ldgallery_.
It mainly describes how to structure the source gallery directory accepted by the _ldgallery_ compiler.
```
[source gallery directory with items and their tags]
|
| ldgallery compiler
v
[generated web gallery with embedded web viewer]
|
| copy
v
[web server]
```
# QUICKSTART GUIDE
## Step 1: initialising the gallery source directory
A new gallery can be initialised by creating a directory containing a gallery configuration file named __gallery.yaml__.
```
./monument-gallery-source
└── gallery.yaml ------ gallery settings file
```
__gallery.yaml__ holds the settings of the gallery.
Its content can be as follows:
```yaml
# gallery.yaml: ldgallery example gallery configuration file.
# See ldgallery(1) for a list of available configuration keys.
galleryTile: Monuments of the World
tagCategories:
- city
```
## Step 2: adding items
A new item, say a picture file named "DSC0001.jpg", can now be added to the directory created at the previous step.
Optionally, some metadata such as a title and some tags can be associated by creating a file named "DSC0001.jpg.yaml" at the same location.
```
./monument-gallery-source
├── gallery.yaml ------ gallery settings file
├── DSC0001.jpg ------- a picture
└── DSC0001.jpg.yaml -- its associated optional sidecar metadata file
```
The sidecar metadata file "DSC0001.jpg.yaml" can have the following content:
```yaml
# DSC0001.jpg.yaml: ldgallery metadata sidecar file for DSC0001.jpg.
# See ldgallery(1) for a list of available keys.
title: The Eiffel Tower
tags:
- city:Paris
- tower
```
## Step 3: compiling the gallery
The gallery can now be compiled by running the following command in a terminal with the right path to the gallery directory created during the previous steps:
```sh
ldgallery \
--with-viewer \
--input-dir ./monument-gallery-source \
--output-dir ./monument-gallery-output
```
If the compiler was installed manually through the extraction of a pre-built archive,
it might be necessary to specify the full path of the installation:
```sh
<installation path>/ldgallery \
--with-viewer=<installation path>/viewer \
--input-dir ./monument-gallery-source \
--output-dir ./monument-gallery-output
```
Running the command above produces a directory named "monument-gallery-output" in the current directory,
which contains the compiled gallery and a web viewer ready to be copied to some web server.
The target web host doesn't need to run any additional software besides a web server correctly configured to serve flat static files.
# TIPS
## Version control
Some standard version-control software such as Git or Mercurial can easily be used to keep track of the evolutions of the gallery directory,
thanks to the text-based format used for the sidecar metadata files.
## Automated compilation and deployment
The gallery can quickly be deployed by using a command such as `rsync`.
The compilation and upload commands can be combined in a Makefile or made part of a script for faster and more convenient deployments.
Such scripted procedure can then further be automated through Continuous Integration hooks.
