Intro

Laph is a program designed for use in physics labs/experiments, born out of the authors abhorrence of Excel. Instead of tables and cells, Laph uses nodes to build a DAG (Directed Acyclic Graph) of computations.

Laph includes an embedded Julia runtime, which is used to compute the graph. Each node (except for input nodes) is backed by a Julia file containing functions that map to each output socket; and this provides an enormous amount of flexibility when it comes to processing the data.

Requirements

• A C++14 compliant compiler
• Qt 5.11 or higher
• Julia 1.0 or higher
• CMake 3.8.0 or higher

Roadmap

• Create a draggable canvas and nodes/sockets/wires
• Embed Julia
• Initial version of a lazily-evaluated graph engine
• Undo/redo [in progress]
• Unit tests
• Support for saving the node graphs (including node settings and vector data)
• Plotting support (most likely using QCustomPlot)
• Optimize the graph engine

Quickstart

Assuming we are in the cloned repo directory:

mkdir build && cd build
cmake ..
make

Note that the path to the Julia libraries/headers are expected to be in JULIA_LIB_PATH and JULIA_INCLUDE_PATH, respectively.
