We want to be able to run those tests (or most of them) on +every engine. Prior to `regex 1.9`, we used to do this with a hodge podge soup +of macros and a different test executable for each engine. It overall took a +longer time to compile, was harder to maintain and it made the test definitions +themselves less clear. + +In `regex 1.9`, when we moved over to `regex-automata`, the situation got a lot +worse because of an increase in the number of engines. So I devised an engine +independent format for testing regex patterns and their semantics. + +Note: the naming scheme used in these tests isn't terribly consistent. It would +be great to fix that. + +[regex-test]: https://docs.rs/regex-test diff --git a/vendor/regex/testdata/anchored.toml b/vendor/regex/testdata/anchored.toml new file mode 100644 index 000000000..0f2248d09 --- /dev/null +++ b/vendor/regex/testdata/anchored.toml @@ -0,0 +1,127 @@ +# These tests are specifically geared toward searches with 'anchored = true'. +# While they are interesting in their own right, they are particularly +# important for testing the one-pass DFA since the one-pass DFA can't work in +# unanchored contexts. +# +# Note that "anchored" in this context does not mean "^".
