Return the arguments that were passed to program itself. Strips off the initial program from the unprocessed command line. i.e. If a program started as:

> node myprogram.js --flag bla

The arguments list will be ["--flag","bla"].

The unprocessed command line that was used to start this program. On ‘'Node’' the first arguments will often be of the form ["node","interactive.js",...].

The backend compiler name, like gcc, clang, cl, clang-cl, mingw, or icc (and js for JavaScript).

The current compiler version.

Return the processor maximum address size in bits (8(*)std/core/int/(*): (int, int) -> intsizeof(vaddr_t)). This is usually equal to the get-cpu-pointer-bitsstd/os/env/get-cpu-pointer-bits: () -> ndet int but may be smaller on capability architectures like ARM CHERI.

Return the main processor architecture: x64, x86, arm64, arm32, riscv32, riscv64, alpha64, ppc64, etc.

Return the size of boxed values in the heap (8(*)std/core/int/(*): (int, int) -> intsizeof(kk_box_t)). This is usually equal to 8(*)std/core/int/(*): (int, int) -> intsizeof(void*) but can be less if compressed pointers are used (when compiled with --target=c64c for example).

Return the available CPU's. This is the logical core count including hyper-threaded cores.

Return the processor natural integer register size in bits.

Note: Usually this equals the get-cpu-size-bitsstd/os/env/get-cpu-size-bits: () -> ndet int and get-cpu-pointer-bitsstd/os/env/get-cpu-pointer-bits: () -> ndet int on modern cpu's but they can differ on segmented architectures. For example, on the old x86 FAR-NEAR model, the addresses are 32-bit but the integer register size is 16-bit. Or on the more recent-x32 ABI the addresses and object sizes are 32-bits but the architecture has 64-bit integer registers.

Is the byte-order little-endian? If not, it is big-endian; other byte orders are not supported.

Return the processor maximum pointer size in bits (8(*)std/core/int/(*): (int, int) -> intsizeof(void*)). This is usually equal to the get-cpu-address-bitsstd/os/env/get-cpu-address-bits: () -> ndet int but may be larger on capability architectures like ARM CHERI.

Return the processor maximum object size in bits (8(*)std/core/int/(*): (int, int) -> intsizeof(size_t)). This is usually equal to the get-cpu-int-bitsstd/os/env/get-cpu-int-bits: () -> ndet int but may be different on segmented architectures.

Get the environment variables for this program.

Returns the value of an environment variable name (or Nothingstd/core/types/Nothing: forall<a> maybe<a> if not present).

Return the main OS name: windows, linux, macos, unix, posix, ios, tvos, watchos, unknown. Sometimes has a dash subsystem, like: unix-<freebsd,openbsd,dragonfly,bsd>, and windows-mingw.
