Python Checktestdata
Checktestdata is a tool to verify the syntactical integrity of test cases in programming contests like the ACM ICPC. It allows you to specify a simple grammar for your testdata input files, according to which the testdata is checked.
This is a Python 3.10 compatible reimplementation of the checktestdata program.
[!NOTE] As of now, the python implementation only supports strict file validation. The arguments
whitespace-okandgenerateare not supported.
Documentation
- Introduction to the Checktestdata Language.
- The CTD language specification at the DOMjudge Checktestdata repository.
- The Regex Syntax.
Installation
Requirements:
- PyPy >= v7.3.15 (preferred)
- CPython >= 3.10 (alternative)
The package can be installed directly from pypi:
pypy3 -m ensurepip
pypy3 -m pip install checktestdata
pip install checktestdata
Use
You can use this program to run .ctd validators in the same way as the checktestdata binary:
pyctd validator.ctd [-d | --debug] < testcase
You can also use the programm to convert .ctd files into standalone python applications:
pyctd validator.ctd --convert [name] [-d | --debug]
[!TIP] The generated validator might not be easy to read, cosider adding
-dto include the original code as comments.
Extensions
This checktesdata implementation supports the --constraints_file argument and can be used with BAPCtools to check the constraints of a problem.
