Interacting with Proskomma using a Node script
There are simple scripts for using Proskomma from the command line in the Proskomma repo. eg
cd scripts
node ./do_graph.js ../test/test_data/usfm/hello.usfm example_query.txt
The script imports a USFM or USX file into Proskomma and then runs the query contained in a text file against it, outputting the result to stdout. on un*x systems you can redirect that result to a file:
node ./do_graph.js ../test/test_data/usfm/hello.usfm example_query.txt > ~/my_result.json
If you want to write your own script to do something different, the code for do_graph.js would be a good starting point.
