GPX Concatenator is a Python project that provides a set of scripts for concatenating and colorizing GPX (GPS Exchange Format) files.

The project consists of the following files:

1. gpx_concatenator.py: This file contains the GPXConcatenator class, responsible for concatenating multiple GPX files. It takes a list of input file paths, an output file path, and optional flags to enable metadata and colorization. The concatenate_files method extracts tracks from the input files using the GPXFile class and appends them to the output GPX file's XML structure. If colorization is enabled, the GPXColorizer class assigns distinct colors to the tracks and adds color metadata to the GPX file.

2. gpx_colorizer.py: This file contains the GPXColorizer class, which colorizes tracks in a GPX file. It assigns distinct colors to each track based on its name and adds color information to the GPX file's XML structure.

3. gpx_file.py: This file contains the GPXFile class, providing methods for working with individual GPX files. It initializes with a file path, parses the GPX file's XML structure, and extracts metadata and track elements.

4. main.py: This file serves as the entry point of the project. It demonstrates how to use the GPXConcatenator class to concatenate and colorize GPX files. The script initializes the GPXConcatenator class with input file paths, an output file path, and flags for metadata and colorization. The concatenate_files method performs the concatenation and colorization process.

To install gpx-concatenator, you can use pip, the Python package manager. Open a terminal and run the following command:

pip install gpx-concatenator

Once installed, you can use the gpx-concatenator command to concatenate and colorize GPX files. Here's an example usage:

gpx-concatenator -i <input-directory> -o <output-file-name> -m -c

Replace <input-directory> with the directory containing the input GPX files, and <output-file-name> with the desired name of the output GPX file. The -m flag enables metadata in the output file, and the -c flag enables coloring of the tracks.

The following command-line arguments are available:

• -i, --input-dir: Specifies the directory containing the input GPX files. The default value is input.

• -o, --output-file: Specifies the name of the output GPX file. The default value is output.gpx.

• -m, --enable-metadata: Enables metadata in the output GPX file. This is an optional flag.

• -c, --enable-coloring: Enables coloring of the tracks in the output GPX file. This is an optional flag.

For more information on available command-line arguments, use the -h, --help flag:

gpx-concatenator --help

Place the GPX files that you want to concatenate in the specified input directory. The files will be concatenated in alphabetical order based on their names.

The concatenated GPX file will be created with the specified name in the current working directory. If the file already exists, it will be overwritten.
