FFF

Fast file search. Used by the search_codebase tool and the TUI to generate filepath / code autocompletions.

Source: https://github.com/dmtrKovalenko/fff

Building

Nova vendors the generated C header at vendor/fff/fff.h, but does not commit the platform-specific dynamic library. Build it from a gitignored checkout of fff.

git clone --depth 1 https://github.com/dmtrKovalenko/fff third_party/fff
cd third_party/fff
make build-c-lib

The Nova runtime looks for the library in this order:

  • macOS: vendor/fff/libfff_c.dylib, third_party/fff/target/release/libfff_c.dylib, then libfff_c.dylib on the loader path.
  • Linux: vendor/fff/libfff_c.so, third_party/fff/target/release/libfff_c.so, then libfff_c.so on the loader path.
  • Windows: vendor\\fff\\fff_c.dll, third_party\\fff\\target\\release\\fff_c.dll, then fff_c.dll on the loader path.

Updating the header

Regenerate fff.h from the FFF repository when the C ABI changes:

cd third_party/fff
make header
cp crates/fff-c/include/fff.h ../../vendor/fff/fff.h
