Then add reference to the language in the navbar by adding a new language entry to the dropdown
https://github.com/Frooodle/Stirling-PDF/blob/main/src/main/resources/templates/fragments/navbar.html#L80
https://github.com/Frooodle/Stirling-PDF/blob/main/src/main/resources/templates/fragments/navbar.html#L306
and add a flag svg file to
https://github.com/Frooodle/Stirling-PDF/tree/main/src/main/resources/static/images/flags
Any SVG flags are fine, i got most of mine from [here](https://flagicons.lipis.dev/)
If your language isnt represented by a flag just find whichever closely matches it, such as for Arabic i chose Saudi Arabia
For example to add Polish you would add
```
<a class="dropdown-item lang_dropdown-item" href="" data-language-code="pl_PL">Polish</a>
<a class="dropdown-item lang_dropdown-item" href="" data-language-code="pl_PL">
<img src="images/flags/pl.svg" alt="icon" width="20" height="15"> Polski
</a>
```
The data-language-code is the code used to reference the file in the next step.

To run the application without Docker, you will need to manually install all dependencies and build the necessary components.
Note that some dependencies might not be available in the standard repositories of all Linux distributions, and may require additional steps to install.
The following guide assumes you have a basic understanding of using a command line interface in your operating system.
It should work on most Linux distributions and MacOS. For Windows, you might need to use Windows Subsystem for Linux (WSL) for certain steps.
The amount of dependencies is to actually reduce overall size, ie installing LibreOffice sub components rather than full LibreOffice package.
### Step 1: Prerequisites
Install the following software, if not already installed:
- Java 17 or later
- Gradle 7.0 or later (included within repo so not needed on server)
- Git
- Python 3 (with pip)
- Make
- GCC/G++
- Automake
- Autoconf
- libtool
- pkg-config
- zlib1g-dev
- libleptonica-dev
For Debian-based systems, you can use the following command:
```bash
sudo apt-get update
sudo apt-get install -y git automake autoconf libtool libleptonica-dev pkg-config zlib1g-dev make g++ java-17-openjdk python3 python3-pip
```
### Step 2: Clone and Build jbig2enc (Only required for certain OCR functionality)
```bash
git clone https:github.com/agl/jbig2enc
cd jbig2enc
./autogen.sh
./configure
make
sudo make install
```
### Step 3: Install Additional Software
Next we need to install LibreOffice for conversions, ocrmypdf for OCR, and opencv for patern recognition functionality.
Install the following software:
- libreoffice-core
- libreoffice-common
- libreoffice-writer
- libreoffice-calc
- libreoffice-impress
- python3-uno
- unoconv
- pngquant
- unpaper
- ocrmypdf
- opencv-python-headless
For Debian-based systems, you can use the following command:
```bash
sudo apt-get install -y libreoffice-core libreoffice-common libreoffice-writer libreoffice-calc libreoffice-impress python3-uno unoconv pngquant unpaper ocrmypdf
pip3 install opencv-python-headless
```
### Step 4: Clone and Build Stirling-PDF
```bash
git clone https://github.com/Frooodle/Stirling-PDF.git
cd Stirling-PDF
./gradlew build
```
### Step 5: Move jar to desired location
After the build process, a `.jar` file will be generated in the `build/libs` directory.
You can move this file to a desired location, for example, `/opt/Stirling-PDF/`.
You must also move the Script folder within the Stirling-PDF repo that you have downloaded to this directory.
This folder is required for the python scripts using OpenCV
### Step 6: Other files
#### OCR
If you plan to use the OCR (Optical Character Recognition) functionality, you might need to install language packs for Tesseract if running none english scanning.
##### Installing Language Packs
1. Download the desired language pack(s) by selecting the `.traineddata` file(s) for the language(s) you need.
2. Place the `.traineddata` files in the Tesseract tessdata directory: `/usr/share/tesseract-ocr/4.00/tessdata`
Please view [OCRmyPDF install guide](https:ocrmypdf.readthedocs.io/en/latest/installation.html) for more info.
**IMPORTANT:** DO NOT REMOVE EXISTING `eng.traineddata`, IT'S REQUIRED.
### Step 7: Run Stirling-PDF
```bash
./gradlew bootRun
or
java -jar build/libs/app.jar
```
Remember to set the necessary environment variables before running the project if you want to customize the application the list can be seen in the main readme.
You can do this in the terminal by using the `export` command or -D arguements to java -jar command:
```bash
export APP_HOME_NAME="Stirling PDF"
or
-DAPP_HOME_NAME="Stirling PDF"
```

Simply use environment variables APP_HOME_NAME, APP_HOME_DESCRIPTION and APP_NAVBAR_NAME with Docker or Java.
If running Java directly, you can also pass these as properties using -D arguments.
Using the same method you can also change the default language by providing APP_LOCALE with values like de-DE fr-FR or ar-AR to select your default language (Will always default to English on invalid locale)
