python bindings for c++ reflection library (xo-pyreflect)

Getting Started

build + install dependencies

• github/Rconybea/xo-pyutil
• github/Rconybea/xo-reflect

build + install

$ cd xo-pyreflect
$ 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-pyreflect installed to ~/local2/lib

PYTHONPATH=~/local2/lib python
>>> import xo_pyreflect
>>> dir(xo_pyreflect)
['SelfTagging', 'TaggedRcptr', 'TypeDescr', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__']
>>> xo_pyreflect.TypeDescr.print_reflected_types()
<type_table_v[0]:>

(Not immediately interesting: no reflected types in pyreflect itself)

Development

build for unit test coverage

$ cd xo-pyreflect
$ 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-pyreflect
$ 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
