# GravTools
GravTools is an open source software toolbox for processing relative gravity surveys developed at the Austrian
Federal Office of Metrology and Surveying (BEV).
- The source code is hosted on github.com: https://github.com/ahellers/GravTools
- The python package is hosted at: https://pypi.org/project/grav-toolbox/
# Installation
## Install python package with pip:
`pip install grav-toolbox`
### Optional dependency for GIS data export
GravTools allows to export station- und observation-results to shapefiles for import and analysis in GIS programs.
To enable these features the optional package "geopandas" needs to be installed by executing:
`pip install grav-toolbox[gis]`
## Installation issues on Centos 8:
* **1. Carry out installation steps describes above**
* **2. Install QT5, if required**
* `sudo yum install qt5-qtbase-devel.x86_64`
## Installation issues on Ubuntu 20.04:
After just installing PyQt5 with pip3 the following error occurred when trying to actually run a PyQt GUI: qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This issue was resolved by installing the QT dev tools (Designer, etc.):
`sudo apt-get install qttools5-dev-tools`
## Test installation
In a virtual environment.
* Editable installation with pip: `pip install -e .`
* Or: `make test_pack`
* Uninstall: `pip uninstall grav-toolbox`
* Or: `test_pack_uninstall`
# Packaging
With setuptools and the build package.
## Create a source and binary distribution (sdist and wheel)
* Set up setup.cfg and pyproject.toml in the project root directory
* With make and the predefined makefile: `make build`
* Without make: `python3 -m build`
The created package (wheel and source distribution) is located in the "dist" directory.
## Push package to pypi.org
Define user credentials in /home/.pypirc
* `twine upload --verbose dist/*` or
* `make pypi_push`
# Create a stand-alone Windows executable
For creating a Windows executable (stand-alone application, without python installation) the
package "auto-py-to-exe" can be used (see: https://pypi.org/project/auto-py-to-exe/). This is a
simple graphical user interface (based on the chrome browser) that allows to define all settings
for the package "PyInstaller" (see: https://www.pyinstaller.org/).
Creating a Windows executable with auto-py-to-exe was tested on Windows 10.
Follow these steps to create an executable on a Windows machine:
* **1. Install Python3**
* With installer from https://www.python.org/downloads/windows/
* Add python3.x to the Windows search path and install pip!
* **2. Install virtualenv and create a virtual environment** in CMD
* a. `pip install virtualenv`
* b. Change to project directory (`cd ..`)
* c. Create virtual environment: `virtualenv env`
* d. Activate it: `env\Scripts\activate.bat`
* Deactivate with `deactivate`
* **3. Install gravtools**: `pip install gravtools[gis]`
* **4. Install auto-py-to-exe**: `pip install auto-py-to-exe`
* **5. Try to run the GravTools**
* Type `gt` in the command line interface (virtual environment must be active)
* **6. Create exe with auto-py-to-exe**
* Run the CMD Window as administrator!
* a. Start auto-py-to-exe in CMD: `auto-py-to-exe`
* b. Select the script location (select: gravtools/scripts/run_gui.py)
* c. Select "One File" and "Console based" (in addition to teh GUI a console will appear)
* d. Start conversion py pressing the big blue button on the GUI bottom
* e. The exe file will be save at a new "output" directory. Move the file to: "Windows_executables"
# Create HTML documentation with sphinx:
Sphinx is used to create an API documentation based on docstrings. Run make in the gravtools/doc directory:
* `>>>make html_doc`
# Guidelines and conventions
## Code style:
* Respect the PEP conventions on python coding!
* PEP 8 -- Style Guide for Python Code: https://www.python.org/dev/peps/pep-0008/
* The maximum line length is 120 characters
* Use **type hints**: https://www.python.org/dev/peps/pep-0484/
* Use docstrings according to the numpy standard: https://numpydoc.readthedocs.io/en/latest/format.html#docstring-standard
* They are useful to generate the documentation automatically
* Example: https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_numpy.html
* Comment code, if necessary!
* Use English language for the code, docstrings and comments
## Documentation and docstring style
* The API reference is created with sphinx (https://www.sphinx-doc.org/).
* Docstrings have to follow the numpy standard, see: https://numpydoc.readthedocs.io/en/latest/format.html#docstring-standard
* Examples: https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_numpy.html
* Contrary to the numpy standard license and copyright information is provided at least in the package and module docstrings.
* Package documentation via docstring in __ini__.py files
* Module documentation via docstring at first lines of py-file
* Documentation of classes, class methods and functions via docstrings
## Command line interface and executable scripts
* The command line interface is realized via entry points (console_scripts) in setuptools (python packaging tool)
* Input arguments are handled with argparse
* Executable scripts are located in gravtools/scripts
