Parser for Python syntax built using Scallion
Run the lexer
sbt:spp> run tokenize examples/django_request.py
Run the parser with raw display
sbt:spp> run parse examples/django_request.py
Run the parser with pretty printing
sbt:spp> run pprint examples/pprint_test.py
Run the parser on an entire folder and display execution time
sbt:spp> run parsedir <folder_path>
Run CPython on an entire folder and display execution time
$ python python/performance_measurement.py <folder_path>
First, we have to export the tree to JSON with Python
$ python python/tree_serializer.py json examples/django_request.py examples/django_request.json
After that, we can run the comparison from SBT. The tree produced
by the Scala implementation is displayed, along with the result of the comparison.
Both JSON files are stored in debug/ref.json and debug/output.json and
can be compared manually as well.
If the script displays JNothing, JSON4S did not find any difference with the tree from
CPython. It means that the comparison was sucessful.
run compare examples/django_request.py examples/django_request.json
Some examples of files from well-known open source projects such as Djanog, Tensorflow, Pytorch
and Flask are available in the examples/ folder.
