LLVM-TEST-MUSTACHE-SPEC(1)

NAME
llvm-test-mustache-spec - LLVM tool to test Mustache library compliance

SYNOPSIS

llvm-test-mustache-spec [inputs…]

DESCRIPTION

llvm-test-mustache-spec tests the mustache spec conformance of the LLVM mustache library. The spec can be found here: <https://github.com/mustache/spec>

To test against the spec, simply download the spec and pass the test JSON files to the driver. Each spec file should have a list of tests for compliance with the spec. These are loaded as test cases, and rendered with our Mustache implementation, which is then compared against the expected output from the spec.

The current implementation only supports non-optional parts of the spec, so we do not expect any of the dynamic-names, inheritance, or lambda tests to pass. Additionally, Triple Mustache is not supported. Unsupported tests are marked as XFail and are removed from the XFail list as they are fixed.

The tool prints the number of test failures and successes in each of the test files to standard output.

EXAMPLE

            $ llvm-test-mustache-spec path/to/specs/\*.json
