#!/bin/sh

# Checks syntax-highlight.lua, the shipped source-filter. The real Scintillua
# collection is not assumed anywhere, because the fake lexer module under
# extensions/fake-lexers drives every path through the filter
# deterministically. The unit checks run twice per interpreter, once with the
# fake lexers found and once with an empty directory so the escaped fallback
# is what everything renders through. The run through cgit itself places the
# fake lexers beside the config file, which is the probe the filter documents
# for a scintillua directory next to cgitrc.
