geoff(@GeoffreyHuntley):🆕 I got tired of nix build pasting a novel into the terminal and burning up my ChatGPT subscriptions. Introducing the fix: https://t.co/FazwRheImR A 10,000 line build output containing an error reduces allocations from 359,114 bytes to 609 bytes whilst retaining the full log HATEOS style. Not a wrapper. Not `nix build 2>/tmp/log`: - It source-patches Nix. - Same `nix build`. - Same exit status. - An app printing "error" does not fail the build. What you get on the console: - progress every 15s - a few bounded excerpts - SUCCESS in 19s | 1 diagnostic What you get on disk: - every builder line
