A modern, delicious implementation of the Nix package manager, focused on correctness, usability, and growth — and committed to doing right by its community

Find a file

Matthew Bauer fa8515d7ec Set regex_constants::match_continuous for quicker search match_continuous limits the search to the current start position, instead of searching the entire file. On libc++, this improves performance dramatically: $ time /nix/store/70ai68dfm6xbzwn26j5n4li9di52ylia-nix-3.0pre20200728_c159f48/bin/nix print-dev-env >/dev/null /nix/store/70ai68dfm6xbzwn26j5n4li9di52ylia-nix-3.0pre20200728_c159f48/bin/ni 2.39s user 0.19s system 64% cpu 4.032 total $ time /nix/store/cwjfxxlp83zln4mfyy1d2dbsx7f6s962-nix-3.0pre20200728_dirty/bin/nix print-dev-env >/dev/null /nix/store/cwjfxxlp83zln4mfyy1d2dbsx7f6s962-nix-3.0pre20200728_dirty/bin/nix 0.09s user 0.05s system 65% cpu 0.204 total Fixes #3874		2020-07-29 00:57:20 -05:00
