rjsonnet-py
Python bindings to Rust jrsonnet crates (Rust implementation of Jsonnet language).
Installation
pip install rjsonnet
Usage
This module provides two functions:
def evaluate_file(filename: str) -> str: ...def evaluate_snippet(filename: str, src: str) -> str: ...
In the latter case, the parameter filename is used in stack traces,
because all errors are given with the "filename" containing the code.
Keyword arguments to these functions are used to control the virtual machine. They are:
max_stack(number)gc_min_objects(number, ignored)gc_growth_trigger(number, ignored)ext_vars(dict, string to string)ext_codes(dict, string to string)tla_vars(dict, string to string)tla_codes(dict, string to string)max_trace(number)import_callback(see example in tests/)native_callbacks(see example in tests/)preserve_order(bool, preserve object field order during manifestification)gc(bool, default:True, run garbage collection automatically)
The argument import_callback can be used to pass a callable, to trap the Jsonnet import and importstr constructs.
This allows, e.g., reading files out of archives or implementing library search paths.
The argument native_callbacks is used to allow execution of arbitrary Python code via std.native(...).
This is useful so Jsonnet code can access pure functions in the Python ecosystem, such as compression, encryption, encoding, etc.
If an error is raised during the evaluation of the Jsonnet code, it is formed into a stack trace and thrown as a python RuntimeError.
import rjsonnet
# evaluate a jsonnet file
rjsonnet.evaluate_file("filename.jsonnet")
# evalute a jsonnet code snippet
rjsonnet.evaluate_snippet('filename', 'jsonnet code snippet')
# Collect cyclic garbage in current thread created by jrsonnet
# to avoid memory leak, it's not necessary to call this function
# unless you have passed `gc=False` to `evaluate_file` or `evaluate_snippet`
rjsonnet.gc()
