Geoflow

Flowchart tool for geo-spatial data processing. Highly experimental with many rough edges!

Installation

As part of geoflow-bundle

This the recommended way since it will also include the commonly used plugins and flowcharts to get you started quickly. Also binary pacakges are available.

Building from source

Requires compiler with c++17 support (see https://en.cppreference.com/w/cpp/compiler_support).

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DGF_BUILD_GUI=OFF
cmake --build . --parallel 4 --config Release

dependencies

nlohmann JSON at least version 3.10.5

Usage

Command line interface (`geof`)

Usage: 
   geof [-v | -p | -n | -h]
   geof <flowchart_file> [-V] [-g] [-w] [-c <file>] [--GLOBAL1=A --GLOBAL2=B ...]

Options:
   -v, --version                Print version information
   -p, --list-plugins           List available plugins
   -n, --list-nodes             List available nodes for plugins that are loaded
   -h, --help                   Print this help message

   <flowchart_file>             JSON flowchart file
   -V, --verbose                Print verbose messages during flowchart execution
   -g, --list-globals           List available flowchart globals. Cancels flowchart execution
   -w, --workdir                Set working directory to folder containing flowchart file
   -c <file>, --config <file>   Read globals from TOML config file
   --GLOBAL1=A --GLOBAL2=B ...  Specify globals for flowchart (list availale globals with -g)

examples

Print version information: geof --version

Print help: geof --help

Running a flowchart with default globals: geof <flowchart file>

List available globals: geof <flowchart file> --list-globals

Running a flowchart with user-specified global values: geof <flowchart file> [--config <TOML config file with globals>] [--GLOBAL1=value1 --GLOBAL2=value2 ...]

Command line specified globals have the highest priority and will override default values and/or config file provided values.
