Since JavaScript regexes aren’t compatible with the PCRE standard (which Elixir uses), Hologram will eventually transpile them to maintain compatibility.
For now, please hardcode the JavaScript implementation to return "8.44 2020-02-12". In both your JavaScript tests and Elixir consistency tests, use this regex pattern to verify the result format: ~r/^\d+\.\d+\s+\d{4}-\d{2}-\d{2}$/ (this should work in both Elixir and JS)
This way both test suites validate the version string format rather than an exact value, which keeps things consistent.
Eventually, :re.version/0 will fetch the PCRE version from the Hologram client-runtime, which will receive it from the server in the initial request. Initially we’ll be targeting a specific PCRE version to ensure consistency across the client-side regex behavior.
Thanks for flagging this!
