th2-tool

Small Python CLI to modify Therion .th2 files generated from TopoDroid to work better with Therion cartography style.

Quick Start

Run the script directly:

python3 th2_edit.py <file.th2> [command] [options]

From this folder:

python3 -m unittest discover -s tests

If no command is provided, the script applies all default conversions:

• line pit -> line floor-step
• line chimney -> line ceiling-step -reverse on
• line rock-border -> add or force -close on

Project Layout

• th2_edit.py: main CLI script.
• tests/: unit tests for conversion and CLI behavior.
• data/: sample and working .th2 files (for example data/AS-1p.th2).

Run commands from the repository root so paths like ./data/AS-1p.th2 work as shown.

Examples

Default conversion (no command):

python3 th2_edit.py ./data/AS-1p.th2 --in-place

Notes

• --in-place and --output are mutually exclusive.
• By default, --in-place creates <name>.th2.bak.
• Use --no-backup to disable backup creation.
