python bindings for c++ printjson library (xo-printjson)

Getting Started

build + install dependencies

• github/Rconybea/xo-pyutil
• github/Rconybea/xo-printjson

build + install

$ cd xo-pyprintjson
$ 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

PYTHONPATH=~/local2/lib:$PYTHONPATH python
>>> import xo_pyprintjson
>>> dir(xo_pyprintjson)
['PrintJson', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__']
>>> dir(xo_pyprintjson.PrintJson)
['__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'instance', 'print']

Development

build for unit test coverage

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

display cmake variables

• -L list variables
• -A include 'advanced' variables
• -H include help text

$ cd xo-pyprintjson/build
$ cmake -LAH
