xo-umbrella2/xo-pyprocess

python bindings for c++ stochastic process library (xo-process)

Getting Started

build + install dependencies

• github/Rconybea/xo-process
• github/Rconybea/xo-reactor
• github/Rconybea/xo-pyutil
• github/Rconybea/xo-pyreflect
• github/Rconybea/xo-pyprintjson
• github/Rconybea/xo-pyreactor

build + install

$ cd xo-pyprocess
$ mkdir build
$ cd build
$ INSTALL_PREFIX=/usr/local  # or wherever you prefer, e.g. ~/local
$ cmake \
    -DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
    -DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
    -DCMAKE_INSTALL_PREFIX=${INSTALL_PREFIX} ..
$ make
$ make install

(also see .github/workflows/main.yml)

Examples

Assumes xo-pyprocess installed to ~/local2/lib/python

PYTHONPATH=~/local2/lib/python:$PYTHONPATH python
>>> import xo.process
>>> dir(xo.process)
['BrownianMotion', 'ExpProcess', 'RealizationSource', 'RealizationTracer', 'StochasticProcess', 'UpxAdapterSink', 'UpxEvent', 'UpxEventStore', 'UpxToConsole', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'make_brownian_motion', 'make_exponential_brownian_motion', 'make_realization_printer', 'make_realization_source', 'make_tracer']
>>>

Development

build for unit test coverage

$ cd xo-pyprocess
$ mkdir build-ccov
$ cd build-ccov
$ cmake \
    -DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
    -DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
    -DCODE_COVERAGE=ON \
    -DCMAKE_BUILD_TYPE=Debug ..

LSP (language server) support

LSP looks for compile commands in the root of the source tree; while Cmake creates them in the root of its build directory.

$ cd xo-pyprocess
$ ln -s build/compile_commands.json  # supply compile commands to LSP

Examples

Assumes xo-pyprocess installed to ~/local2/lib/python

PYTHONPATH=~/local2/lib/python python
>>> import pyprocess
>>> dir(pyprocess)
