-Subject: [PATCH] Replace regex-onig by regex-fancy in minimal-application
-
-The default "application" feature enables "minimal-application", which
-in turn pulls in the "regex-onig" feature of syntect. This brings in the
-onig crate (version 6.4.0) and its dependency onig_sys, which fail to
-build with GCC 15 due to C23 keyword conflicts.
-
-It is not possible to simply update the onig crate from bat itself,
-since its version is pinned indirectly by syntect. To avoid this
-dependency and fix the build, replace "regex-onig" with "regex-fancy" in
-"minimal-application". This makes bat use the pure-Rust fancy-regex
-engine instead of Oniguruma, removing the need for onig_sys and allowing
-the package to build with GCC 15.
-
-There is an an ongoing discussion about removing Oniguruma from bat
-since Oniguruma has been declared archived:
-
-see https://github.com/sharkdp/bat/issues/3285
-
-The Upstream project for now is refusing to use fancy-regex as default.
-
-Upstream: not submitted
