Should I just add it back to the next developer's meeting issue once it is created? ---------------------------------------- Feature #16029: Expose fstring related APIs to C-extensions https://bugs.ruby-lang.org/issues/16029#change-81375 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- As discussed with @tenderlove here: https://github.com/ruby/ruby/pull/2287#issuecomment-513865160 We'd like to update various data format parsers (JSON, MessagePack, etc) to add the possibility to deduplicate strings while parsing. But unfortunately the `rb_fstring_*` family of functions isn't available to C-extensions, so the only available fallback is `rb_funcall(str, rb_intern("-@"))` which most parsers will likely consider too slow. So the various `rb_fstring_*` functions would need to be public. Proposed patch: https://github.com/ruby/ruby/pull/2299 -- https://bugs.ruby-lang.org/ Unsubscribe:
