WIP

This is a new functional language with the first-class array support and planned object-oriented features. ficus compiler generates a portable C/C++ code out of .fx files.

The code is distributed under Apache 2 license, see the LICENSE

The compiler is written in Ficus itself and needs C/C++ compiler and make utility.

cd <ficus_root>
make
FICUS_PATH=./lib FICUS_CFLAGS=-I./runtime ./ficus -run -O3 examples/fst.fx
# or
# ./ficus -I ./lib -cflags "-I./runtime" -run -O3 examples/fst.fx

FICUS_PATH and FICUS_CFLAGS are the two variables to setup to make ficus usable from any directory.

• The first one, FICUS_PATH, should point to the standard library (<ficus_root>/lib), but can also contain other directories separated by : on Unix and ; on Windows. Note that if a compiled module imports other modules from the directory where it resides, that directory does not need to be included.

• The second one, FICUS_CFLAGS, is used by C/C++ compiler to build the produced .c/.cpp files. The generated files include ficus runtime headers, and the path to the runtime directory needs to be specified via command line option -cflags or the environment variable.

run ./ficus --help to get more complete up-to-date information about command line parameters

here is brief summary:

./ficus [-app|-run|...] [-O0|-O1|-O3] [-I<extra_module_path>]* <scriptname.fx> [-- <script arg1> <script arg2> ...]

• -app (the flag is set by default) generates C code for the specified script as well as for the imported modules (one .c file per one .fx file), then run the compiler for each of the generated .c files and then link the produced object files into the final app. Use FICUS_CFLAGS and FICUS_LINK_LIBRARIES environment variables to pass extra options to C compiler, e.g. -ffast-math -mavx2 -lmimalloc etc. The compiled app, as well as the intermediate .c and .o files, is stored in __build__/<scriptname>/<scriptname>. Override the output name with -o option.
• -run builds the app (see flags -app) and then runs it.

(see #4 for the decryption and the status)

The compiler was inspired by min-caml (http://esumii.github.io/min-caml/index-e.html) by Eijiro Sumii et al.
