Minim

Minim is a Scheme implementation.

Requires CMake 3.21+ and a C17 compiler.

cmake --preset release
cmake --build --preset release
./build/release/minim             # a REPL
./build/release/minim file.scm    # runs a file

Running a file prints only what it displays or writes. An error stops it with exit status 1.

The dev preset is a debug build with sanitizers and tests. Tests are off otherwise (-DMINIM_BUILD_TESTS=ON enables them).

cmake --preset dev
cmake --build --preset dev
ctest --preset dev       # the tests
ctest --preset stress    # each test again, collecting garbage at every allocation
./build/dev/minim

The stress tests expose missing GC roots under the sanitizers (see docs/design/testing.md). Environment variables do the same for any program (see docs/design/environment.md):

MINIM_GC_NURSERY_BYTES=1 MINIM_GC_RADIX=1 ./build/dev/minim file.scm

The documentation is indexed in docs/README.md: design notes, roadmaps, and plans in progress.
