# archiepixa
|
||||
|
||||
|
||||
`archiepixa` is a minimalist Bash script designed to visualize archives with a webserver. It scans a specified folder and its subfolders, compresses previews using `ffmpeg` and `imagemagick`, and compiles them into HTML files, one for each subfolder.
|
||||
|
||||
The code has been developed for the workshop *[Building collective digital archives]("https://dsignweek.servus.at/program/fri-24/building-collective-digital-archives/")* during the [D*sign Week 2024, Linz]("https://dsignweek.servus.at/"). Powered by [Servus]("https://servus.at")
|
||||
|
||||
|
||||
## Workflow
|
||||
|
||||
- Scans specified folder and subfolders for files
|
||||
- Compresses previews for images, videos, and audio files
|
||||
- Generates static HTML files with customizable CSS styling
|
||||
- Customization of main color, secondary color, background color, and footer text
|
||||
|
||||
|
||||
## System Requirements
|
||||
|
||||
- Bash shell
|
||||
- `ffmpeg` and `imagemagick` packages for media file compression
|
||||
|
||||
## Installation Instructions
|
||||
|
||||
### Installing ffmpeg and imagemagick
|
||||
|
||||
To install `ffmpeg` and `imagemagick`, use the package manager specific to your operating system.
|
||||
|
||||
#### For Ubuntu/Debian:
|
||||
|
||||
```bash
|
||||
sudo apt-get install ffmpeg imagemagick
|
||||
```
|
||||
|
||||
#### For macOS (using Homebrew):
|
||||
|
||||
```bash
|
||||
brew install ffmpeg imagemagick
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
To use `archiepixa`, follow these steps:
|
||||
|
||||
1. Place `archiepixa.sh` in the parent folder of the directory you want to scan.
|
||||
2. Run the script using the following command:
|
||||
|
||||
```bash
|
||||
bash archiepixa.sh -f <folder_name>
|
||||
```
|
||||
|
||||
Replace `<folder_name>` with the name of the folder you want to scan.
|
||||
|
||||
## Getting started
|
||||
|
||||
A practical example:
|
||||
|
||||
```bash
|
||||
cd /var/www/html/
|
||||
git clone http://git.servus.at/servus/archiepixa
|
||||
mv archiepixa/archipiexa.sh ./
|
||||
bash archiepixa.sh -f ""
|
||||
```
|
||||
|
||||
## Customization
|
||||
|
||||
You can customize the appearance of the generated HTML files by modifying the **CSS** within the Bash script.
|
||||
|
||||
You can use flags to modify the background, the main, the second, the third color and you can choose how many colors the dither uses.
|
||||
|
||||
```bash
|
||||
bash archiepixa.sh -f "folder" -b "black" -1 "purple" -2 "rgb('22','45','223')" -3 "#342298" -d "5"
|
||||
```
|
||||
|
||||
Defaults are:
|
||||
|
||||
* -1 "red"
|
||||
* -2 "orange"
|
||||
* -3 "black"
|
||||
* -b "white"
|
||||
* -d "3"
|
||||
|
||||
|
||||
## Cleanup
|
||||
|
||||
To remove the generated HTML files, use the `-r` flag along with the folder name:
|
||||
|
||||
```bash
|
||||
bash archiepixa.sh -f <folder_name> -r
|
||||
```
|
||||
|
||||
To delete both the HTML files and compressed folders, use the `-ra` flag:
|
||||
|
||||
```bash
|
||||
bash archiepixa.sh -f <folder_name> -ra
|
||||
```
|
||||
|
||||
## IMPORTANT!
|
||||
|
||||
**Note:** Avoid placing files named "index.html" within the scanned folders to prevent conflicts.
